Water Use in Semi-arid Northeastern Brazil – Modeling and Scenario Analysis
Abstract
If water is a scarce resource like in the semi-arid Northeast of Brazil, the water use as well as
water quality must be managed in a proactive manner. In order to achieve a sustainable
development of the region, water management decisions should be based on an assessment of
future water use which includes the long-term effects of current activities and policies. In order to
support water management decisions, we performed a scenario analysis of future water use in
Piauí and Ceará in 2025 by
1. compiling, analyzing and integrating information about water use and water management in
Piauí and Ceará,
2. developing the large-scale water use model NoWUM which covers the whole of Piauí and
Ceará and provides sectoral water use estimates for each municipality, and, using NoWUM,
3. computing current (1996/98) water use,
4. deriving water use scenarios for the year 2025, which reflect different possible societal
development paths and water demand management options, and
5. computing water scarcity indicators which show which municipalities will suffer most from
water scarcity.
For all sectors, the increase of water use between today and 2025 is higher in case of the Coastal
Boom and Cash Crops scenario than in case of the Decentralization scenario. Due to increased
water use (in 99% of the municipalities), water scarcity will become more severe in the future,
even though runoff will increase in more than 50% of the municipalities due to climate change
(average climate 2011-2040). The development of water use will predominantly be influenced by
the development of the irrigation sector, above all the extension of irrigated areas. As a first
indicator of water, scenarios of municipal nitrogen loads were computed. Future municipal
nitrogen loads could be smaller than today's if 70% of the waste water in the capitals of the
municipalities is subject to secondary treatment, as steep increase from today's coverage. The
presented scenario analysis can form the basis for further investigating the effect of water
management measures on water use, water scarcity and water quality.

Water Use in Semi-arid Northeastern Brazil – Modeling and Scenario Analysis
1 Introduction
Scarcity of water is a major constraint for development in semi-arid Northeastern Brazil, a region
characterized by recurrent droughts which are related to the El Niño phenomenon. In particular
the rural population, mainly subsistence farmers, suffers from these droughts due to the loss of
crops and livestock. During the last decades, irrigated agriculture has been regarded as the
privileged development option for rural areas, with plans for a multitude of irrigation projects
which have rarely been realized. Nevertheless, the irrigation sector has become the largest water
user in Northeastern Brazil. Today, hopes are high that an extended production of irrigated fruits
for export will strongly improve rural incomes.
For the rural population, access to safe drinking water is difficult and becomes even more
difficult during droughts, as only the urban population (or rather a part of it) is connected to the
public water supply. The public water supply system has, in most cases, problems with serving
the ever increasing number of urban dwellers who, given the convenience of tap water, consume
relatively high amounts of water. In some areas today, and probably more in the future, industry
and tourism are important water user that compete for water with the irrigation sector.
Under the described conditions in Northeastern Brazil, it is necessary to manage both water
supply and water demand. While the construction and proper management of water infrastructure
is the necessary basis for a secure water supply, a concurrent water demand management is
essential for a sustainable economic and social development of the region. Only by a proactive
demand management can the scarce resource water be used efficiently.
Water demand management requires an assessment of present and future water use in which
water use is related to development paths and policy options. Such an assessment is preferably
supported by a water use model which computes sectoral water uses at the appropriate spatial and
temporal resolution. On the one hand, the water use model provides estimates of water use under
current conditions, e.g. how much water is required for irrigated areas in both climatically
average and drought years. On the other hand, it helps to derive scenarios of future water use
which are a decision support for water managers and policy makers.
In this report, we present a water use model for two states in Northeastern Brazil, Piauí and
Ceará. The model computes sectoral water uses in all municipalities. We show the current water
use situation and analyze water use scenarios for the year 2025 which reflect different possible
development paths and water demand management options. A detailed description of the model,
the data and the scenario assumptions is given in Appendix A. Taking into account the runoff

Water Use in Semi-arid Northeastern Brazil – Modeling and Scenario Analysis
modeled by the hydrological modeling group of the WAVES project (Axel Bronstert and Andreas
Güntner, Potsdam Institute for Climate Impact Research), we computed a water scarcity index in
water use is compared to water availability. Water use generally leads to a degradation of water
quality; as a first rough indicator for the pollution of surface waters by domestic waste water, we
present scenarios of domestic nitrogen emission.
Our research was conducted in the framework of the Brazilian-German cooperation program
WAVES, financed by the Brazilian research ministry CNPq and the German research ministry
BMBF. The goal of WAVES is to identify possible sustainable development paths for the two
Brazilian states of Piauí and Ceará. Typical for Northeastern Brazil, these states are characterized
by recurrent droughts that strongly affect subsistence farmers, leading to migration to the
metropolitan areas of the country. Within WAVES, a dynamic systems analysis of the
relationship between water availability and migration is done. A singular feature of WAVES is
the development of an integrated model to simulate scenarios of the future of Piauí and Ceará.
The model is created by an interdisciplinary team, in which each specific group is responsible for
one submodule like, for example, our water use model or a hydrological model. The objective is
to provide a tool for regional water management planning and thus to support decision makers in
both states.

2 Methodology
2.1 Large Scale Water Use Model NoWUM
The water use model NoWUM (Nordeste Water Use Model) simulates monthly values of
withdrawal and consumptive water use in all 332 municipalities of Piauí and Ceará (Fig. 1).
Withdrawal water use is the quantity taken from its natural location, while consumptive water use
is the quantity of water lost to evapotranspiration. NoWUM is a stand-alone model as well as a
module of the integrated model SIM of the WAVES project. The model distinguishes five water
use sectors: irrigation, livestock, households, industry and tourism (Fig. 2). Irrigation water use is
8

Water Use in Semi-arid Northeastern Brazil – Modeling and Scenario Analysis
calculated according to the methodology of FAO as a function of climate, irrigated area and type
of irrigated crop (nine different crop classes). Livestock water use is calculated from the number
of animals per species and a species specific water use for Northeast Brazil. We distinguish 11
different livestock species. For calculating the domestic water use, we differentiate households
connected to public water supply and self-supplied households. The water use per capita in a
connected household is calculated from municipality-specific data provided by the water supply
agencies AGESPISA, FNS, CAGECE, SISAR in Piauí and Ceará. Future per capita domestic
water use of connected households is assumed to be a function of income and water price. The
economic concept of elasticities is used to compute the decreasing per capita water use in case of
increasing water price (price elasticity) and the increasing per capita water use in case of
increasing incomes (income elasticity). As no information on water use in unconnected
households is available, a per capita withdrawal water use of 50 l/d is assumed. Industrial water
use is a function of the industrial output and the industrial mix; we consider 19 industry branches
and their branch-specific industrial output per municipality. Future industrial water use is also
influenced by the water price. Like in the case of domestic water use, the application of watersaving technology is assumed to be driven by the water price. Tourism water use is a function of
the touristic overnight stays. A detailed model description, which includes the parameterization
and the data sources, can be found in Appendix A.

2.2 Estimation of nitrogen loads
The return flow is the part of the withdrawn and used water that does not evapotranspirate but is
returned to the environment. If the return water is of appropriate quality it can be reused. Thus, a
water use model would ideally include the quality of the returned water in order to indicate the
water consumption, i.e. the amount of water that cannot be used by a downstream user due to
both evapotranspiration and pollution. Here, as a first indicator for pollution of surface water the
nitrogen load from domestic waste is estimated for every municipality as a function of population
and the existence and efficiency of waste water treatment:

Nitrogen loads from manure (livestock) and mineral fertilizers are not yet taken into account.

2.3 Water use scenarios for 2025
Within the WAVES Program, two reference scenarios for the year 2025 were developed. An
interdisciplinary working group on scenarios developed the narrative storylines and quantified the
driving forces. For a detailed description of the storylines and a complete quantification of the
driving forces please consult Döll et al. (2000). Based on the general storylines and the driving
forces, we derived additional driving forces that are specific to water use modeling. Then, using
the driving forces as input to NoWUM, we developed scenarios of water use in the year 2025
which are consistent with the WAVES reference scenarios. We generated two reference
scenarios, and an intervention scenario which simulates a higher number of households connected
to the public water supply.
2.3.1
Storylines of the two reference scenarios
Both reference scenarios are rooted in current societal developments. Scenario A, the Coastal
Boom and Cash Crops scenario, can be regarded as the business as usual scenario; it represents a
continuation of current trends and reflects general expectations of the future that exist in Piauí
and Ceará. Scenario B, the Decentralization scenario, reflects the beginning development and
increasing attractiveness of the medium-size towns in Piauí and Ceará, the regional centers which
is caused by an improved infrastructure (e.g. universities) in these towns and a decreasing quality
of live in the large metropolitan areas of the country.
Scenario A: Coastal Boom and Cash Crops
In Scenario A, the globalization trend is dominant. The economic, social and cultural differences
between and within countries become smaller and smaller. Economic and technological growth is
rapid, and the global trade strong. Environmental protection and resource conservation is done
only reluctantly.
In such a globalized world, there is a strong economic development in the coastal regions of Ceará
and Piauí (which has a very short coastline only). The main development focus is the metropolitan
area of Fortaleza, with booming commerce and industry. Fortaleza, however, is also subject to the
typical problems of fast growing cities. The infrastructure is always lacking behind the needs of the
population, and the favelas at the outskirts of the city grow. In addition, tourism is becoming an
important economic sector along the coast. The capital of Piauí, Teresina, is only developing slowly
due to its unfavorable location. In those areas of the Hinterland where water is available, the
production of cash crops by large companies dominates over subsistence farming. In the remote
South of Piauí, large scale commercial husbandry is performed.
11
Hauschild and Döll
Water Use in Semi-arid Northeastern Brazil – Modeling and Scenario Analysis
Scenario B: Decentralization: Integrated Rural Development
In Scenario B, the world is more heterogeneous than in Scenario A. The emphasis is on local
solutions to economic, social and environmental problems. Globally, the economic development
is not as strong as in scenario A, whereas environmental protection and social equity more
important.
In such a world, the Northeast of Brazil becomes more or less decoupled from the dominating
centers of Brazil in the South. In Piauí and Ceará, the development is characterized by regional
centers, attractive medium-sized towns with improved infrastructure which become the markets
for local and regional agricultural products. Besides, the agricultural products are processed and
refined by small-scale industry in the regional centers. Economic growth is somewhat weaker
than in Scenario A, and strongest in the water-rich Hinterland where local farmers, due to credits
and education, have increased their productivity. The farmers are supported by the World Bank
and other international institutions who wish to improve the living conditions in crisis-prone
semi-arid regions. Tourism at the coast is increasing due to an increasing number of tourists from
within the two states, but not as strong as in Scenario A.
2.3.2
Spatial resolution of the scenario driving forces
Scenario regions are those spatial subunits of Piauí and Ceará that are assumed to develop in a
homogeneous fashion. The two states were divided into eight scenario regions (Fig. 3):
1. Teresina, the capital of Piauí
2. Metropolitan area of Fortaleza, the capital of Ceará + Port of Pecém
3. Coastal region
4. Southern part of Piauí
5. Region with relatively large potential water resources in Ceará
6. Region with relatively large potential water resources in Piauí
7. Region with small potential water resources in Ceará
8. Region with small potential water resources in Piauí
The scenario regions were derived by taking into account
•
similar (agro)economic conditions
•
administrative boundaries
•
natural conditions (sedimentary vs. crystalline subsurface, location within the river basin,
precipitation)
In case of conflict, the assignment of a municipality to a scenario region was based on the
characteristics that appears to dominate its future development.
12

Water Use in Semi-arid Northeastern Brazil – Modeling and Scenario Analysis
For each scenario region, the driving forces of the scenarios were quantified. For most driving
forces, all the municipalities within a scenario region are assumed to be subject to the same
percentage changes of the driving forces.

2.3.3
Quantifying the driving forces
The driving forces of water use are shown in Fig. 2. For each scenario region, the driving forces
were quantified for both scenarios by taking into account their development in the past (data from
1991 and 1996, in most cases). All the municipalities within a scenario region are assumed to be
subject to the same changes of the driving forces (an exception is the change in irrigated area
where irrigation projects that are planned for certain municipalities are implemented in the
model). If, for example, the annual growth of gross domestic product (GDP) is, in Scenario A, is
2.7% per year in the Coastal region, the GDP in each municipality in the coastal region increases
with this rate, no matter what the current GDP of the municipality is today.
Climate in 2025 is the average of the climate from 2010-2040. The climate scenario was
generated by the WAVES climate group (Gerstengarbe, Potsdam Institute for Climate Impact
Research) by downscaling the results of the global circulation model ECHAM4-OPYC (Röckner
et al., 1996), which are based on the IS92a greenhouse gas emission scenario (Leggett et al.,
1992). Downscaling was done by a cluster analysis of the different climate variables. For detailed
13

listings of all driving forces of water use per scenario region compare Appendix A and Döll et al.
(2000).
Table 1 shows the assumed changes of important driving forces of the water use scenarios
between today and 2025, for both Scenario A (RSA) and Scenario B (RSB). Only the aggregate
values over all eight scenario regions are shown here. The change of most driving forces is
stronger in Scenario A than in Scenario B. Only the total population increase is equal but the
distribution between scenario regions (in brackets) differs. The intervention scenarios assume an
even larger expansion of the public water supply as already assumed in the reference scenarios.
ISA represents the intervention scenario to RSA and ISB to RSB, respectively (Table 8 in
Appendix A).

3 Results
Appendix B contains tables with modeled consumptive and withdrawal water uses in each of the
332 municipalities, distinguishing the five water use sectors. Model results are for 1996/98 and
2025 (reference scenario A Coastal Boom and Cash Crops, reference scenario B
Decentralization: Integrated Rural Development scenario and intervention scenario with
extended public water supply).

3.1.1
States
Table 2 shows the withdrawal and consumptive water use per sector under current conditions
(1996/98), aggregated for the whole of Ceará and the whole of Piauí. In both states, the two most
important water use sectors are irrigation and households. With respect to consumptive use, the
irrigation sector is clearly dominating, which is due to the higher fraction of the withdrawn water
that evapotranspirates during use. In Piauí, livestock water use is a larger fraction of total water
14
Hauschild and Döll
Water Use in Semi-arid Northeastern Brazil – Modeling and Scenario Analysis
use than in Ceará. In Ceará, the industry and the tourism sector use nearly 10% of the water, their
use is negligible in Piauí. The total withdrawal water use in Ceará is twice the water use in Piauí.
This can be explained by the fact that the main driving forces of water use are higher in Ceará
than in Piauí (Table 3). During a year, water use varies by a factor of 3 to 4 between the month
with the lowest and the month with the highest water use; the seasonal variation is caused by the
irrigation sector.

Municipalities
For water management both at the state and the drainage basin level, it is important to have
spatially resolved water use information. NoWUM provides information on water use for each of
the 332 municipalities in Piauí and Ceará. Fig. 4 shows the annual withdrawal water use 1996/98
in each municipality, for all water use sectors. Water use is expressed in mm/yr, i.e. it is
normalized with the area of the municipality and is thus directly comparable to water availability
expressed as runoff in mm/yr. The spatial pattern of irrigation water use (Fig. 4a) is explained by
15
Hauschild and Döll

1) the fraction of the area of the municipality that is irrigated, b) the percentage of crops that are
grown all year round (banana, fruit trees, grass, sugar cane) and c) the interpolated climate data,
which, however, have high uncertainty in the south of Piauí, in the Serra de Ibiapaba and in the
Cariri. Large irrigated areas with fruit trees and vegetable cultivation occur in and around
Teresina, in the Serra de Ibiapaba, in the Curu valley, along the Jaguaribe and in the Cariri region
(Fig. 4a). The Sertão region of Ceará, with its high cattle density, emerges in the livestock water
use map (Fig. 4b). Although the south of Piauí is economically dominated by animal husbandry,
the per area livestock water use is low. The highest domestic water uses occur in the urban
centers of Teresina, Parnaiba and Picos (Piauí) and in the metropolitan area of Fortaleza, Sobral,
the Serra de Ibiapaba and the Cariri (Ceará) (Fig. 4c). Industrial water use also has maximum
values in the urban centers. Industrial water use calculated with option 2 (industry type specific
water intensities from Germany and industrial output from 19 industry types) is in most
municipalities higher than option 1 simulations (direct information on industrial water use from
water works) (Fig. 4d and 4e). The reality might be somewhere in between these two estimates. In
23 municipalities, option 2 provides information on industrial water use whereas it is zero under
option 1. The most attractive coastal municipalities, the metropolitan area of Fortaleza and the
pilgrims hot spot Juazeiro do Norte (Cariri) become evident in the tourism water use map (Fig.
4f). For all water use sectors, water use in Ceará is more intensive than in Piauí. Fig. 4g and 4h
show the total withdrawal water use and the total consumptive water use of all water use sectors
per municipality, respectively.

3.2 Water use in 2025
3.2.1
States
Fig. 5 shows the total withdrawal water use in Ceará and Piauí modeled with NoWUM, in
1996/98 and, for the two reference scenarios, in 2025. In the future we see an increase of water
use in both scenarios in all sectors compared to the present state. The strongest percentage
increase is found in the irrigation, the tourism and the industrial sector. For the state aggregates,
there is a stronger increase in water use in A than in B. It seems in terms of water use the
decentralization scenario is more favorable.
The very small percentage increase of domestic water use is remarkable. Even though an
additional two million people will live in the area, more households are connected to public water
supply systems and people have a higher income than today, domestic water use will barely
increase. This is due to the modeled effect of the pricing of water, assuming a relatively high
price elasticities between -0.55 and 0.3 (decreasing with time) and a yearly increase in the water
price of 6%. In the past ten years, the average annual water price increase in Ceará was 11%.
Without price control the domestic water use in Ceará in the coastal boom scenario would
increase from 226 ⋅ 106 m³ (1997) to 550 ⋅ 106 m³ instead of 297 ⋅ 106 m³ computed with price
control. Thus, the pricing of water can contribute to water saving.

and intervention scenarios A and B [106 m³].
Increasing the number of households connected to the public water supply beyond the increases in
RSA and RSB (intervention scenarios ISA and ISB) increases domestic water use. This is due to
the fact that approx. two million people more are connected and each connected person consumes
18
Hauschild and Döll
Water Use in Semi-arid Northeastern Brazil – Modeling and Scenario Analysis
more water per capita than a self-supplied person. In Ceará, the intervention raises domestic water
use by 14% in A with regard to the reference scenario, and 17% in case of B. In Piauí, the
respective numbers are 7% and 10%. The intervention scenario shows that safe drinking water for
over 80% of the total population in Piauí and Ceará, realized in the intervention scenarios, only
results in a small increase of domestic water use if public water supply is subject to an efficient
water price policy. The increase of total water use by the intervention is insignificant, because it is
dominated by the change of irrigation water use.
3.2.2
Municipalities
For the two reference scenarios RSA and RSB, Figs. 6 to 11 present the difference between
annual water use in 2025 and in 1996/98. Green colors mark a decrease of water use in the future,
yellow and red an increase.
Irrigation: Consumptive irrigation water use in 2025 is higher than today for both reference
scenarios (Fig. 6c and 6d). Consumptive water use is affected by climate change, by the increase
in irrigated areas, and by the crop mix. RSA and RSB only differ with respect to the irrigated
area. Fig. 6b shows the impact of climate change only, which overall leads to a (rather small)
decrease of water use. For the simulations we used the 30-year climate normal 1951-80 to
represent present day climate conditions and the climate normal 2011-2040 for 2025 climate. In
each case, 30 years of irrigation requirements were computed and then averaged. Average
precipitation 2011-2040 is larger than the 1951-1980 average in the north and in large parts of
Ceará (Fig. 6a). However, the effect of the extension of irrigation by far outweighs the effect of
climate change. The spatial pattern of consumptive irrigation water use in both scenarios (Figs. 6c
and 6d) correlates well with the maps of extended irrigated areas (Figs. 6e and 6f). The increase
in irrigated area in case of Scenario B is smaller than in case of Scenario A as not all the irrigation
projects planned in 1998 are assumed to be implemented and also the extension of private
irrigation is smaller than in scenario B. The strongest increases in irrigation water use occur in
those municipalities where new public irrigation project are implemented.
Livestock: Fig. 7 shows the difference of withdrawal livestock use in future compared to the
present state. The spatial pattern in both scenarios reflect the change in the distribution of
(human) population, because in both scenarios the change in livestock populations is assumed to
be proportional to the change in human population.
Domestic: Changes of domestic water use in future compared to the present state (Fig. 8) result
from 1) the change of total population per municipality, 2) an increased number of persons
19
Hauschild and Döll
Water Use in Semi-arid Northeastern Brazil – Modeling and Scenario Analysis
connected to public water supply and 3) a decrease of per capita domestic water use of supplied
persons subject to water price and income increase. Domestic water use decreases in 45% and
increases in 55% of all municipalities in the Coastal Boom and Cash Crops scenario RSA
(Fig. 8a). In the Decentralization scenario RSB we found a decrease in only 25% of the
municipalities and increase in 75% (Fig. 6b), which is due to a less intensive concentration of
population in the coastal region than in RSA. As result of the smaller GDP increase in RSB, the
total increase of domestic water use on state level is less in RSB than in RSA (Fig. 5).
An enforced extension of public water supply to the whole urban and 15% of the rural population
in the intervention scenarios (IS), leads to an increase of domestic water use in 99% of all
municipalities compared to their respective reference scenarios (Fig. 6c and 6d). However, the
increase is in most municipalities very small (<= 1 mm). The strongest increase is found in
Fortaleza, where the intervention increases domestic water use from 386 mm to 432 mm (RSA)
and from 305 mm to 339 mm (RSB).
Industry: Industrial withdrawal water use increases in future due to an increase in industrial
output (expressed as IGDP) (Fig. 9). The industrial mix is assumed to remain the same. In both
RSA and RSB, the strongest absolute increases occur in Teresina, municipalities in the
metropolitan area of Fortaleza as well as Camocim, Itapagé, Crato and Barbalha, as these
municipalities have a relatively high industrial water use today. The increase in RSA is stronger
than in RSB due to the stronger increase of the industrial gross domestic product (IGDP). In both
scenarios, increase of IGDP is assumed to be equal to the increase of GDP. In municipalities
without industry 1996/98, no industry is assumed to be established until 2025.
Tourism: Tourism water use increases in future above all in the coastal municipalities in the
coastal boom scenario (Fig. 10a) and less strong in the decentralization scenario (Fig. 10b). The
water use scenarios do not include establishment of tourism in non-touristic municipalities and
municipalities without tourism potential (classified by EMBRATUR), because tourism water use
would be negligible compared to the domestic water use there.
Total withdrawal water use: In RSA, total withdrawal water use decreases in the water scarce
regions of Piauí and Ceará (Fig. 11a), where population decreases. In both scenarios, the strongest
water use increase occurs in the coastal region, the metropolitan area of Fortaleza and the regions
of Piauí and Ceará with relatively large potential water resources (Figs. 11a and 11b). Besides, the
municipalities for which irrigation projects are planned require much more water than today
(comp. Fig. 6).

Water Use in Semi-arid Northeastern Brazil – Modeling and Scenario Analysis
3.3 Water scarcity
Indicators describe quantitatively the state of a system and are therefore helpful to identify and
describe changes of the system. As simple index for water scarcity, we chose the ratio of
withdrawal water use and the water availability in the municipality of interest. Water availability
in a municipality is defined as the total runoff in all upstream municipalities minus the
consumptive water use in all municipalities upstream of the municipality of interest:
Index _ water _ scarcitym =
total withdrawal water usem
n
runoff m − ∑ consumptive water usen
1
m: municipality for which the index is calculated
n: municipality upstream of m
Consumptive and withdrawal water use are model results from the water use model NoWUM,
while runoff per municipality is simulated by the large-scale hydrological model HYMO-WA
(Bronstert and Güntner) using the 1951-80 climate time series. The higher the index, the more
stress is placed on available water resources by water use. If a large part of the available water is
withdrawn, the usage of water by downstream users can be impaired due to 1) the decreased
streamflow and 2) the low water quality of the return flow. At this time, there is no objective
basis for defining threshold values of the water scarcity index which, for example enables us to
distinguish areas with high water stress from areas of low water stress. If the index is based on
long-term average annual values of runoff and water use (Fig. 12a), a ratio of 0.4 and higher
might indicate severe water stress (Alcamo et al., 2000). However, areas suffering from water
scarcity are better identified by looking at the ratio in a typical dry year (Fig. 12b); this takes into
account that in the case of two areas with the same average ratio but different interannual climate
variability, the area with the higher variability suffers more from water scarcity than the area with
a relatively equable climate. In a typical dry year, water scarcity occurs mainly in those areas in
Ceará and Piauí with small potential water resources. Beyond this, some municipalities, for
example in the Picos and the Cariri region, belong to the areas with large potential water
resources and have critical water scarcity indices. These municipalities have large groundwater
resources, that are not considered to calculate this index, because groundwater resources are not
quantifiable, finally.

Hauschild and Döll
Water Use in Semi-arid Northeastern Brazil – Modeling and Scenario Analysis
If long-term annual average of water availability and water use are taken into account, water
scarcity (critical value > 0.4) is identified only in 5% of the municipalities (Fig. 12 a). Obviously,
a water scarcity indicator based on long-term annual average cannot represent the nature of water
scarcity in Northeastern Brazil. There are two reasons. First, water scarcity is a seasonal problem,
and second, the high interannual climate variability leads to recurrent drought years.
During the rainy season, in March (Fig. 12 b), only few municipalities have a critical water
scarcity index. In the dry season, in September (Fig. 12 c), there is no rainfall and therefore no
runoff in nearly all 332 municipalities. Fig. 13 shows the increasing percentage of municipalities
with critical water scarcity index (> 0.4) from 4% in the rainy season to 100% in the dry season.
Since the natural runoff without considering the large reservoirs is used to calculate the scarcity
index, the seasonal climate variability shapes the curve. In reality, in the dry season, water is
withdrawn from groundwater, large reservoirs and rivers made perennial by reservoir
management. Therefore the water supply situation is less negative than shown here. Nevertheless,
every dry season the governments of Ceará and Piauí need to deploy water trucks to supply
persons in rural areas with drinking water.
The more facilities exist to store the runoff of the wet season for the dry season, the more
appropriate it is to take into account a water scarcity index based on annual averages. Such an
annual index should be derived for the conditions of a typical dry year (year with an annual
rainfall which is exceeded in 90% of all years) and not for long-term average climate, as water
cannot be stored over many years. In the year 1970, 28% of the municipalities suffer much more
from water scarcity (Fig. 12 d) than the 5% under long-term average climatic conditions.
In the future, annual and monthly water scarcity increases in both scenarios compared to the
present state 1996/1998 (Figs. 12 and 13). With respect to annual values, the percentage of
municipalities with a critical water scarcity index increases 2025 in the case of RSA by 6% and
by 1% in RSB compared to the present state (Fig. 13). With respect to the monthly water scarcity
index, differences are highest in the months between the rainy and dry season. In most
municipalities, the increase of runoff due to climate change cannot balance the increase of water
use; water use increases in 90% of the municipalities, and runoff in only 53%. Water scarcity
increases more strongly in the Coastal Boom and Cash Crops scenario than in the
Decentralization scenario, which is mainly due to the different increases of irrigated areas.

3.4 Water quality
Scenarios of future nitrogen emissions to surfaces water show the effect of an extended and
improved treatment of municipal waste water. Here, we only present the results for reference
scenario B. In 1997 only 11 out of 332 municipalities had waste water treatment plants, and
approximately 2-44% of the waste water of this municipalities was treated. For RSB it is assumed
that in 2025 all capitals of municipalities have a wastewater plant, and that 30% of their
wastewater is cleaned. For the intervention scenario (ISB), the fraction is 70%. Figure 14 shows
the changes of nitrogen emissions to surface water in 2025 compared to the present state. Due to
the increased number of treatment plants, municipal nitrogen emissions to surface waters increase
less than the number of inhabitants (Fig. 14). The emission reduction is stronger if the treatment
efficiency is higher (difference between primary and secondary treatment). The effect of
secondary treatment of 30% of the waste water of the capitals of the municipalities (RSB,
secondary treatment) is similar to the effect of a primary treatment of 70% of the waste water
(ISB, primary treatment). If 70% of the waste water undergoes secondary treatment (ISB,
secondary treatment) nitrogen loads in five out of the eight regions would be smaller than today.

4 Summary and conclusions
A scenario analysis of future water use and water scarcity in the semi-arid states Piauí and Ceará
in the semi-arid Northeastern Brazil was performed. The analysis was done with the help of the
newly developed water use model NoWUM which computes withdrawal and consumptive water
use in each of the 332 municipalities, distinguishing five water use sectors. The scenario analysis
shows how water use might develop between today and the year 2025, taking into account
changes of climate, population, income, industrial output and water prices as well as changes in
irrigation (areas, crops, water use efficiency) and public water supply (connected households). For
the first time, municipality-specific estimates of current water use are provided. For all sectors,
the increase of water use between today and 2025 is higher in case of the Coastal Boom and Cash
Crops scenario than in case of the Decentralization scenario. Due to increased water use (in 99%
of the municipalities), water scarcity will become more severe in the future, even though runoff
will increase in more than 50% of the municipalities due to climate change (average climate
2011-2040).
28
Hauschild and Döll
Water Use in Semi-arid Northeastern Brazil – Modeling and Scenario Analysis
The development of water use will predominantly be influenced by the development of the
irrigation sector, above all the extension of irrigated areas. If all the now irrigation projects
planned in 1998 will be implemented by the year 2025 and private irrigation increases in a similar
fashion than in the last decade (Coastal Boom and Cash Crops scenario), irrigated area will
increase by a factor of 4.5 and irrigation water use by a factor of 3.8 (withdrawal water use) and
4.1 (consumptive water use). Then, irrigation would account for 68% of the total water
withdrawal of 2513 km3/yr in Piauí and Ceará compared to 44% of 1016 km3/yr today. In the
alternative Decentralization scenario, irrigated area increases by a factor of 2, and irrigation water
use (withdrawal) by a factor of 1.7. In this scenario, the irrigation sector uses 51% of the total
withdrawn water (1466 km3/yr) in 2025. The impact of climate on irrigation water use is small.
Domestic water use increases where population increases but due to the high price elasticity and
the increase of water price, increases are low. In an exemplary fashion, the impact of a water
management measure on water use, here the extension of public water supply to a larger number
of household, is shown. This measure increases domestic water use in urban centers, but does not
significantly effect total water use (Fig. 5).
Although industrial water use becomes more important in the future, above all in Ceará, irrigation
and households remain the dominant water users. In Ceará, industrial water use will become the
third most important sector, switching its rank with the livestock sector.
There is a strong interdependence between water use and water quality. When water is
withdrawn, used and then returned to the river, its quality usually decreases, sometimes to a
degree that precludes a further use downstream. An indicator for the impact of domestic water use
on water quality is the nitrogen load which can be decreased by waste water treatment. Scenarios
of future nitrogen emissions to surfaces water show the effect of an extended and improved
treatment of municipal waste water. If in 2025 (Decentralization scenario), 70% of the waste
water produced in the capitals of the municipalities will be subject to secondary waste water
treatment, nitrogen loads in five out of the eight scenario regions would even be smaller than
today (even though population increases).
The presented scenario analysis can form the basis for further investigating the effect of water
management measures on water use, water scarcity and water quality. New intervention scenarios
could explore the consequences of, for example, implementing or not certain irrigation projects,
with certain areas, crop types and irrigation water use efficiencies. In order to assess the impact of
to technical measures to increase water availability, e.g. new reservoirs, on water scarcity, the
scenarios of future water use (or demand) must be taken into account. With respect to water
29

quality, it will necessary to assess not only the domestic nitrogen loads, but also the agricultural
loads. Then, the interplay between land use and water quality could be analyzed.

Large-scale water use model NoWUM
for modeling water management in Ceará and Piauí
Model description, data and scenario assumptions
Version 1.0
January 2000
1 Overview
The water use model NoWUM (Nordeste Water Use Model) calculates both withdrawal water
use (quantity of water withdrawn from its natural location) and consumptive water use (quantity
of water lost to evapotranspiration). The use quantity best suited for the assessment of water
scarcity, water depletion (quantity of water used that cannot be reused), is a quantity in-between
withdrawal use and consumption use, which due to the lack of information on water quality is not
yet computed in the present model version 1.0. Within NoWUM, five water use sectors are
distinguished: irrigation use, livestock use, domestic use, industrial use and tourism use.
The irrigation water use is calculated with the methodology of FAO (FAO, 1992). Livestock
water use is computed as a function of livestock-specific water use and numbers of the different
livestock types. With respect to domestic water use, the specific water use of people connected to
the public water supply and those not connected are differentiated. Two methods are used to
calculate the industrial water use: one based on the assessment of different water sources (public
supply, self-supply, raw water supply); the second multiplies the industrial gross domestic
product with a water use intensity per industrial branch. Multiplying the touristic overnight stays
with a touristic water use per overnight stay gives the water use in the tourism sector.
Computations are performed on the municipal scale for all municipalities of Ceará and Piauí in
the reference year 1996. Here, Ceará consists of 184 and Piauí of 148 municipalities. The
municipalities in Ceará are numbered sequentially from 1 up to 184, those of Piauí from 185 to
332. The output of NoWUM are monthly sectoral withdrawal and consumptive water use values
in each municipality. However, in the case of livestock water use and industrial water use, the
monthly values are derived from annual averages, while in the case of irrigation they are the sum
of 10-day-values.

2 Irrigation water use
2.1 Method
The consumptive irrigation water use (net irrigation requirement) is computed following the
method of CROPWAT (FAO, 1992). The crop-specific net irrigation requirement within one
growing period Ic is calculated as

I c = ∑ Kc ,i E p,i − Peff ,i

crop coefficient (crop-specific) [-]
potential evapotranspiration [mm/d]
effective precipitation [mm/d]
Using effective precipitation instead of total precipitation P takes into account that not all the rain
is available to the crops. According to the USDA Soil Conservation Service Method (as given in
FAO, 1992),
Peff = P(4.17 - 0.2 P) / 4.17 for P < 8.3 mm/d
Peff= 4.17 + 0.1 P
for P ≥ 8.3 mm/d
2.2 Climate data input
NoWUM requires daily values of precipitation and potential evapotranspiration, which are
provided by the WAVES-subproject Large-scale Hydrologic Model.
As the FAO approach uses 10-day time steps, NoWUM aggregates daily values of precipitation
and evapotranspiration into 36 time steps per year. The Integrated Model SIM of WAVES
handles with 365 or 366 days per year, respectively. Hence, NoWUM sums up three times 10
days (April, June, September, November); 10, 10 and 11 days (January, March, May, July,
August, October, December); in February 10, 10 and 8 or 9 days to get three time steps per
month.
2.3 Input of crop data
The crop data required are:
1. irrigated areas per crop in each municipality
2. crop-specific data like planting date, growing periods and crop coefficients per growing
period.
First, we determined nine main irrigated crops classes (Table 1). The crop-specific planting date
was derived from annual schedules of DNOCS irrigation perimeters in Ceará and Piauí (DNOCS
1994a, 1995a, 1996a) and the recent Agricultural Census (IBGE 1998a, 1998b), while data on
crops coefficients and length of growing period are taken from CROPWAT (FAO, 1992).

Irrigated areas in 1996/98
Information about the size of irrigated areas at state level in Ceará and Piauí diverges widely. The
Agricultural Census of Ceará and Piauí (IBGE 1998a, 1998b) provides information for all
municipalities in both states, but Brazilian experts say that the total irrigated areas published by
IBGE are strongly overestimated.
For Ceará, we used the most reliable information from COGERH (1995, 1998a) and SRH (1998),
instead of data of the Agricultural Census. COGERH keeps a register of total irrigated farm land
in some municipalities of the Curu and the Jaguaribe valley. SRH registers all irrigation licenses
given to farmers in Ceará. These licenses include also the irrigated area per crop. The total
irrigated area per municipality is taken from the COGERH and the SRH-register. The lacking
data in 23 municipalities are filled with downscaled IBGE data considering expert knowledge.
Because in the municipalities Ico and Morada Nova the registered data seem to be much to high,
they are replaced with data from the Agricultural census. Here licenses are already given for
public irrigation projects which will be implemented in the future.
In Piauí, data of irrigated areas are taken from the Agricultural Census, because more reliable data
are lacking. There is no reasonable correlation between the total irrigated area per municipality
and the sum of the harvested areas of significant irrigated temporary crops per municipality, both
given in the Agricultural Census of Ceará and Piauí (IBGE 1998a, 1998b). In many municipalities
the total irrigated area is considerably less than the sum of the areas of the temporary crops.
Additionally the permanent crops should be integrated. That calls the given total irrigated area in
question. Hence, the harvested areas of irrigated temporary crops per municipality are considered
35
Hauschild and Döll
Water Use in Semi-arid Northeastern Brazil – Modeling and Scenario Analysis
as their irrigated areas in the year 1996. Furthermore, the harvested area of banana and all fruit
trees are set as their irrigated areas assuming that these crops are always irrigated. The total
irrigated area per municipality is calculated as the sum of the harvested area of the irrigated
temporary crops, the harvested area of banana and the harvested area of fruit trees. The total
irrigated area is scaled down to 13170 ha, because Brazilian experts do not regard 18148 ha of
irrigated land in Piauí in 1996 to be realistic. For this purpose, the size of irrigated areas in the
municipalities close to markets (Floriano, Miguel Alves, Oeiras, Parnaiba, Picos, Piripiri, São
Raimundo Nonato, Teresina and União, all together 8625 ha) are retained. In all other
municipalities the irrigated area is reduced by factor 3.
2.3.2
Irrigated areas in 2025
The increase of irrigated areas up to the year 2025 is designed for the two reference scenarios of
WAVES, the Coastal Boom and Cash crops scenario (RSA) and the Decentralization: Integrated
Rural Development scenario (RSB) (Döll et al., 2000). The total irrigated area is the sum of large
public irrigation projects and private irrigation. The increase of both parts is considered
differently in both reference scenarios. While the Coastal Boom and Cash Crops scenario
continues the business as usual, the Decentralization scenario shows an alternative development.
The present governments of Ceará and Piauí favor a strong increase of large public irrigation
projects. These projects are already planned for years at locations best suited for irrigation and
provide opportunities for the agro-industry, and middle-sized and small farmers. RSA reflects this
policy. On the other hand, an increase of irrigated land of private farmers distributed upon the
whole territory matches best the story line of RSB. In RSA, the total irrigated area of 1996/98 is
increased until 2025 by a factor of 4.5, and in RSB by a factor of 2.
Coastal Boom and Cash Crops scenario (RSA)
For the year 2025 it is assumed that all large public irrigation projects planned in 1998 will be
implemented in the specified municipalities given in Lopes Neto (1998). Additionally, an
increase of the private irrigated area is assumed per scenario region such that by 2025 irrigated
areas increased as listed in table 2. The additional total private irrigated area per scenario region is
equally distributed to all municipalities of the region.
Decentralization scenario (RSB)
For the year 2025 is assumed that only a quarter of the large public irrigation projects planned in
1998 will be implemented in the specified municipalities. The reasoning is that these projects
were begun in the end of the 90s, but not concluded under the political conditions of
decentralization. The increase in private irrigation is also assumed to be smaller in RSB than in
RSA.
The additional private irrigation area is distributed in each scenario region in the following way:
a) 50% of this area is distributed in proportion to the present irrigated area (assuming that existing
irrigation occurs in best suited places), and
b) 50% of this area is equally distributed in all municipalities of the scenario region (assuming the
promotion of a decentralized economic activity).

Not only the total irrigated area, but also the crop mix is changed in the scenarios. 50% of the
new irrigated area per municipality gets the same crop distribution as in 1996/98. The other part
is planted according to the standard crop mix of 2025. "Standard crop mix" means the average
crop mix of a state (Piauí or Ceará). Brazilian experts expect that the percentage of banana, fruit
trees, vegetables and cotton will rise, the percentage of beans, maize and grass will remain at the
same size, and the percentage of rice and sugar cane will decrease (Table 3).

2.4 Calculation of irrigation water use
In NoWUM, the net irrigation requirement irr_req of a planted area is calculated as

The irrigation requirement is calculated for each municipality i, for every ten-day time step of the
year l and for all crops k, which are planted in the municipality. The crop coefficient Kc varies
within the growing season. It is 0 before the crop's planting and after its harvest. Altogether four
development steps are distinguished with fixed crop coefficients during the first and the third
step. The coefficient during the second and the fourth step augments or decreases linearly. During
the second step it starts with the value of the first step and finishes with the value of the third
step. During the fourth step it starts with the value of the third step and finishes with the given
final value of the fourth step.

If the irrigation requirement for a crop of each municipality [mm = l/m²] is multiplied with the

NoWUM works with a constant water use efficiency of 0.6 for all municipalities in 1996/98
according to Brazilian expert knowledge. In the future Brazilian experts expect that the irrigation
water use efficiency will increase to 0.7. The higher efficiency considers the technological
change; since NoWUM does not include a price control of irrigation. Moreover, this version does
not consider multiple cropping (planting crops with short growing periods two or three times a
year) yet, consequently the irrigation water use is underestimated.
3 Livestock water use
Based on the Agricultural Census (IBGE 1998a, 1998b), eleven types of livestock are
distinguished. For 1996 the number of animals per species are taken from the Agricultural
Census. In the scenarios of the future animal populations grow with the same annual population
growth rates as used for the human population per municipality. The withdrawal water use for
livestock is computed by summing up the products of the livestock-specific water use (Table 5)
and the number of that livestock in each municipality. The consumptive water use is computed by
multiplying the withdrawal water use with a typical livestock water use efficiency of 1.0 (USGS,
1998). Only yearly values are computed, which are - in order to obtain monthly values - just
divided by twelve.

4 Domestic water use
4.1 Method
Domestic water use is the product of population and the water use per person. People connected
to the public water supply (piped water supply) are differentiated from those that are not
connected. While the water use of people connected to the public water supply is determined
from municipality-specific monthly data on connected households and supplied volume, the water
use of people not connected to the public water supply is assumed to be a constant in the present
version of NoWUM. For the scenarios of the future the water use per capita of a person connected
to the public water supply is modeled as a function of the water price and the average income of
the person.
4.2 Input data of population and public water supply volumes
4.2.1
Present state
NoWUM requires data of the total population and the population connected to public water
supply. The latest population data (total, urban and rural) are published in the Demographic
Census of IBGE (1997), reference day 01-08-1996. With monthly growing rates of population per
municipality, which we took from internal reports of the public water supply companies
AGESPISA (1997) and CAGECE (1997), we computed monthly total and urban population for
the year 1997. The supplied population is calculated as follows for every municipality:
hhconn * hhsizeurban
popsupp = 

if hhconn * hhsizeurban < popurban
if hhconn * hhsizeurban ≥ popurban
(F 4.1)
supplied population of municipality
urban population of municipality
amount of households connected to public supply
urban household size per municipality
The data of amount of households connected to public supply were derived from internal reports
of AGESPISA (1997), CAGECE (1997), FNS (1997), SISAR (1998), FUNASA (1998) and
SOHIDRA (1999) as well as the data of urban household size from the Demographic Census on
IBGE (1997). In the present model version, the supplied population is calculated outside of
NoWUM.
For computing the specific water use of people connected to the public water supply, the
produced water volume of the supply companies for each municipality are necessary. In the
accessible internal reports of 1997 from AGESPISA, CAGECE and FNS, these data are only
given by CAGECE for all months and by AGESPISA from January up to March 1997. Instead of
this, we take the billed water volumes, provided by all companies for all months, as input data,
although the billed water volume in general is smaller than the produced (and supplied) volume,
in some municipalities up to factor 2. If households have no water meter, they pay for a fixed
volume of 10 m³, although they probably consume more water. This could explain the large
40
Hauschild and Döll
Water Use in Semi-arid Northeastern Brazil – Modeling and Scenario Analysis
difference between the two water volumes. Finally the water use efficiencies per municipality are
read from a separate input file, although we have no local data yet.
4.2.2
Scenarios
The WAVES working group Scenarios designed two reference and one intervention scenario up
to the year 2025 for the eight scenario regions (Döll et al., 2000). The two reference scenarios are
(A) the "Coastal Boom and Cash Crops scenario and (B) the Decentralization: Integrated Rural
Development scenario. The report of working group Scenarios presents the story lines of the
scenarios and detailed information on how the working group came up with the quantification of
the driving forces in detail. The growth of the total population is the same in both scenarios
(Table 6) but it is different in the scenario regions in scenario A and B (Table 7). In the field of
water management scenarios, assumptions of the percentage of persons connected to public water
supply were made for the reference and intervention scenarios (Table 8). The intervention
scenario assumes an even larger expansion of the public water supply as already assumed in the
reference scenarios. The explicit increase of the connections to public water supply expresses the
structural change in the future.

* RS: reference scenario / IS: intervention scenario
For the future NoWUM calculates the water use per capita per person connected to public water
supply as a function of prices and income (see below). The scenarios include rates of change in
gross domestic product per capita per scenario region (Table 9) as well as an annual increase of
the water price. In order to come up with a reasonable price increase, a ten year time series (19891998) of water tariffs from CAGECE was analyzed. In this period occurred several monetary
reforms. The base tariff for the first 15 m³ increased at 11% per year from 1989 to 1998.
Nowadays, CAGECE's water price covers operation and maintenance costs (O&M costs), and it
is expected that the O&M costs will rise in future. For the scenarios a constant water price
increase of 6% per year is assumed for all scenarios in all scenario regions.

4.3 Computation of domestic water use
In NoWUM, the specific water use of people connected to the public water supply and those not
connected are differentiated. We have no information on the water use of people not connected
to the public water supply. As a first estimate, we assume a value of 50 l/d/p, a value defined by
Gleick (1996) as the basic human water requirement. This might underestimate water use
particularly when people have their own private wells. Thus, the domestic withdrawal water use
is computed as follows:
wd _ domestic[i ][m] = popsupp[i ][m]∗ con _ supp[i ][m]
+ ( poptotal[i ][m] − popsupp[i ][m])∗ con _ nsupp[i ][ m]

withdrawal use per non-supplied person [m³/month/p]
Consumptive water use is computed by multiplying the withdrawal water use with a typical
domestic water use efficiency of 0.2, which is the average value for the USA (USGS, 1998)
Economists use the concept of elasticities to consider the responsiveness of consumers' purchases
to varying price. A measure of this responsiveness, the elasticity of demand with respect to a
demand determining variable, is defined as the percentage by which the demand changes in
response to a one percent change in the variable. The most frequently used elasticity concept is
the price elasticity, which is defined as the percentage change in water use if price is changed by
one percent. The income elasticity of demand is a related concept: it measures the percentage
change in quantity demanded associated with a one percent change in consumer income. Almost
all estimates of long run price elasticity of residential water demand in the U.S. seem to fall
between -0.3 and -0.7, meaning that other factors held constant, a ten percent increase in price
would lead to a 3-7% decrease in the amount of water purchased (Young, 1998). Income
43

Water Use in Semi-arid Northeastern Brazil – Modeling and Scenario Analysis
elasticity is found to be small but positive; an increase in income brings about a less than
proportional increase in quantity consumed.
The future water use per capita per person connected to water supply is calculated as a function of
the water price and the average income (GDP per capita). It is calculated for each municipalities
as follows:
[(

V j +1 = ε p , j +1 ∗ rp, j +1 + εi , j +1 ∗ ri , j +1 + 1 ∗ V j

NoWUM uses a linear decreasing price elasticity from 1996 to 2025; it starts with -0.55 (value
for Northeast of Brazil, (BNB/PBLM, 1997)) in 1996 and ends with -0.3 (average value for
Europe and U.S.). According to Gomez (1987), NoWUM uses a constant income elasticity of 0.7.
The Brazilian value of 0.78 was reduced, because the scenarios consider explicitly new
connections.
5 Industrial use
5.1 Methods and calculation
Two methods were developed to calculate the range of the industrial withdrawal water use. With
method 1, industrial water use is computed based on municipality-specific information of the
waterworks (IWUWW) and from COGERH (IWURW) and a statewide estimate of the amount of
water that is self-supplied. With method 2, the industrial output of 19 industry branches in each
municipality is taken into account as well as industry-specific water use intensities (water use per
industrial output) typical for Germany. For most municipalities, method 1 leads to a smaller value
than method 2. The real values might be somewhere in between. The consumptive water use is
calculated from withdrawal water use using an industrial water use efficiency of 0.2 (USGS,
1998).

In the scenarios of the future the industrial water use is also a function of prices in both options as
showed in the following.

Prices stand indirectly for technological change. Due to the lacking of industrial specific data,
NoWUM uses also a price rate of 6% per year for the industrial water use scenarios as derived
from CAGECE's data for the domestic water use. The price elasticity decreases linear between
1997 and 2025 from -0.74 (value for Northeast of Brazil, BNB/PBLM (1997)) to -0.4 (average
value for Europe).
5.2 Input data
5.2.1
Input of industrial water use data
Industry gets water from different sources. Mostly the small industry is supplied by the public
waterworks (IWUWW). Often industry additionally supplies itself from own wells or reservoirs
(IWUSS). In Ceará water intensive industry like breweries and industrial districts buy raw water
(IWURW) directly from COGERH, the state company of water management who manages the
big reservoirs.
The IWUWW for municipalities of Piauí were averaged over data of AGESPISA for April 1998
and January 1999. For Ceará only data of CAGECE supplied municipalities were available; the
monthly averages of 1998 were used.
Marwell Filho (1995) published the self-supplied industrial water use for the watersheds of Piauí.
The author remarked that these data are probably too low, because making this investigation,
firms were interviewed by telephone and not all firms answered. To get an IWUSS per
municipality, the water was equally divided to all municipalities within a basin having firms in
1991. Piauí's capital Teresina has the biggest industrial concentration of Piauí. It's special
position was taken into account assigning half of the self-supplied water in the "Poti" basin to
45
Hauschild and Döll
Water Use in Semi-arid Northeastern Brazil – Modeling and Scenario Analysis
Teresina and the rest equally portioned to all other municipalities in the watershed. The IWUSS
of Piauí is 1.57 times higher than the IWUWW of Piauí (state averages). This unique scale factor
was used to compute the IWUSS for the municipalities of Ceará already having an IWUWW.
The IWURWs for the four municipalities of Ceará were taken from COGERH's bill 1998.
5.2.2
Correction factor
In some municipalities the situation is contradictory: according to the information from the
waterworks, they do not have an industrial water use (IWU) but they do have an IGDP. Their
IWU was computed by method 2 described above. Therefore, a correction factor c was necessary.
It reduces the IWU to a size corresponding with the measured data of IWU. The cCeará is 0.554
and cPiauí is 0.215. The c for one state each was calculated as

Input of industrial water use intensity
The application of method 2 needs an industrial water use intensity per industrial branch. Since
these data are not yet available for Brazil, we used data from German industry. To link the
Brazilian with German data, a common classification of industry branches was necessary. Even
Ceará and Piauí have some differences in their classifications. Therefore, the German system was
taken as basis and all data were transformed into this classification considering 19 industrial
branches.

A second unification was necessary to compare economic data of several times and places. For
the calculations within the industrial sector, all data were transformed into US$ of 1995.
Table 10 lists the industrial water use intensity (WUI) per industrial branch for Germany 1995.
The branch specific WUIs were computed with annual data of the industrial gross domestic
product (IGDP) per branch and the water used in firms per branch in Germany (Statistisches
Bundesamt, 1998, 1999).
5.2.4
Input of industrial gross domestic product (IGDP)
The availability of data of IGDP in Ceará and Piauí is very different. For all municipalities of
Ceará branch specific data from 1993 to 1996 exist in the internal database of IPLANCE.
Whereas for Piauí, SEPLAN (1997) published the total gross domestic product (GDP) of Piauí
1996 and SUDENE (1996a, 1996b) published preliminary data of sectoral GDPs for the three
main sectors: agriculture, industry and services for 1995. Neither data of the total GDP per
municipality nor the IGDP per municipality do not exist for Piauí.
Branch-specific IGDPs for the all municipalities of Piauí were assigned in three steps:
1) Assuming that Piauí and Ceará have the same firm-specific IGDP per industrial branch, for
each municipality of Piauí an IGDP was assigned via the number of firms per branch and an
IGDP/firm per branch:

industrial gross domestic product per firm per branch [US$1995/firm], mean value of Ceará
The IGDPs/firm per branch are average values for the state of Ceará 1995. They were calculated
from the number of firms per branch and municipality (IPLANCE, 1997) and the IGDP per
branch and municipality (internal data of IPLANCE). This procedure was used, because the
number of firms per branch and municipality were the only industrial data available for both
states (IPLANCE, 1997; FIEPI, 1991).
2) For those municipalities of Piauí which only have an industrial water use IWUWW but no
firms, the total IGDP resulted from the quotient of their IWUWW and an average industrial water
use intensity of Piauí (IWUIPiauí). The IWUIPiauí was calculated from all municipalities of Piauí
having both, IGDP and IWUWW; it's value is 5.442 m³/1000 US$1995. For comparison: the
average IWUI of Ceará is 4.475 m³/1000US$ and of Germany 15.87 m³/1000US$.
47
Hauschild and Döll
Water Use in Semi-arid Northeastern Brazil – Modeling and Scenario Analysis
3) Municipalities of Piauí which neither had firms in 1991 nor industrial water from AGESPISA
1998/99 got the IGDP zero.
Finally, for the computation of industrial water use the following IGDP data per branch per
municipality were used: for Ceará the given data by IPLANCE, for Piauí the self-produced IGDP
data as described above.
5.2.5
Scenarios
The important driving force of the industrial water use scenarios is the industrial gross domestic
product (IGDP) while all other factors like industrial mix, water use intensity and the fraction of
IGDP on total GDP are held constant for the scenarios. The annual IGDP per municipality is
calculated from the total GDP per year and municipality and it's percentage of GDP in 1997. The
annual changing population multiplied by the annual increasing GDP per capita (see Table 9)
gives the total GDP per municipality. Driving forces set for one scenario region are used for all
municipalities within this region. With NoWUM, structural change of industry could be shown if
the industrial mix will be varied. To do this in a sophisticated way, macroeconomic knowledge
has to be consulted.
6 Tourism water use

A water use efficiency of 0.2 (USGS, 1998) is used to calculate the tourism consumptive water
use out of the tourism withdrawal water use.
6.2 Input data
6.2.1
Present state
The present number of tourists per "touristic" municipality in Piauí was personally given by the
co-director of the tourism agency of Piauí PIEMTUR. Touristic municipalities here means
touristic municipalities and municipalities with tourism potential classified by EMBRATUR
(1997). For the municipalities of Ceará the number of tourists was derived from several regional
studies on tourism in Ceará (Table 11).
48
Hauschild and Döll
Water Use in Semi-arid Northeastern Brazil – Modeling and Scenario Analysis
As medium stay of tourists per municipality the given values of 9 days for the Ibiapaba region
(SETUR/CE 1998 c), 8 days for the coastal region (SETUR/CE 1997 a) and 5 days for the Cariri
region (SETUR/CE 1998 d) and the rest of Ceará (SETUR/CE 1997 c) are used in the
simulations. For Piauí the medium values of Ceará are taken over: 8 days for the coastal
municipalities and 5 days for the municipalities of the interior.
The water requirement in hotels varies between 300 and 500 l/d/p (Stephenson, 1998). In
NoWUM is used a high touristic water requirement of 500 l/d/p in the coastal municipalities
reflecting the better hotel infrastructure (swimming pools, irrigation of gardens) and relating
activities of tourists (several baths per day). In all other municipalities a water requirement of 300
l/d/tourist is used.
6.2.2
Scenarios
For the two reference scenarios we made different assumptions for the number of tourists and the
touristic water use, while the medium stay of tourists is used as for the present state. For the
"coastal boom scenario" (A) the number of tourists increases with factor 5 towards the present
state in the municipalities of the coastal region and the metropolitan area of Fortaleza. In the
municipalities of the interior it increases only with factor 3. In the "decentralization scenario" (B)
the number of tourists is assumed to increase with factor 3 towards the present state in all
municipalities. While for the scenario B the touristic water use is used as in the present state, it
differs in scenario A. In the coastal boom scenario A the touristic water use for the municipalities
of the regions Teresina, metropolitan area of Fortaleza and the coastal region is set to 500 l/p/d; in
all other municipalities to 300 l/p/d. For pilgrims NoWUM uses only 100 l/p/d.

It is obvious that in 7 not all pilgrims were
counted, because in the estimation of 720.157
tourists/a only 168.517 pilgrims are included
and 1.831.483 pilgrims lacking. Consequently,
the same number has to be added to the total
number of tourists. It rises from 3.829.000 to
5.660.483 tourists per year.
Persons arriving at Fortaleza with any kind of
transport (plane, bus, car, etc.) are assumed to
stay 5 d in Fortaleza. Following they visit
other municipalities (the percentile quota to
single municipalities in: 1). Source 2 includes
the monthly division.
The number of tourists is equally divided into
all of the seven municipalities of the Ibiapaba
region. The monthly division of tourists is
taken over from the situation in Fortaleza (2).
23,4% of the 720.157 tourists in the Cariri
region have a religious motivation for their
visit. The tourists, except pilgrims, are monthly
divided as in Fortaleza (2). Single
municipalities get the number of tourists
according to their number of beds (from: 3).

Pilgrims appear only in the month of February,
July, September and November. They are
distributed to the three municipalities Juazeiro

This amount of pilgrims appears during the 10

7 Model input
Most of the parameters are read from one input file each. The data are read into matrixes of size
number of municipalities and number of months or number of days. NoWUM needs several input
data files:
1. daily values of precipitation per municipality
2. daily values of evapotranspiration per municipality
3. planting data, growing periods and crop coefficients of irrigated crops
4. irrigated areas per crop of one year per municipality
5. numbers of livestock species per municipality
6. total population of one year per month per municipality
7. supplied population of one year per month per municipality
8. monthly water volume supplied by public water supply system per municipality
9. water use efficiency of public water supply system per municipality
10. best guess of industrial water use per municipality
11. industrial gross domestic product per industrial branch per municipality
12. water use intensity per industrial branch (constant for all municipalities)
13. number of tourists per municipality
14. medium stay of tourists per municipality
15. tourist water use per municipality
Some driving forces of the scenarios are given only per scenario region such as population
growth, price rates and growth of gross domestic product per capita. They are read from
customized input files.
Appendix 1 gives examples for the input data files. Data of input files 1 to 4 are used to calculate
the irrigation water use, data of file 5 for livestock water use, data of files 6 to 9 for domestic
water use, data of files 10 to 12 for industrial water use and data of files 13 to 15 for tourism
water use calculation. For executing NoWUM, all data file names (input and output) are either
read from the desktop or from file input.
8 Model output
NoWUM computes monthly sectoral and total withdrawal and consumption water use
[m³/month] for all municipalities of Ceará and Piauí. Examples of some of the output files are
given in Appendix 2:
1. Total withdrawal water use of all sectors per month per municipality
2. Total consumptive water use of all sectors per month per municipality
3. Withdrawal water use of irrigation per month per municipality
4. Consumptive water use of irrigation per month per municipality
5. Withdrawal water use of livestock per month per municipality
Consumptive water use of livestock per month per municipality
