Urban growth in arid environments: Developing water sustainability
indicators for Abu Dhabi (UAE).
Abstract
The United Arab Emirates (UAE) face a serious water problem. It has a very dry climate, high
evaporation rate, combined with large water consumption from fast growing population,
economic activities and uncontrolled uses of water for irrigation. Currently, UAE has one of the
largest water footprints in the world. Groundwater is overexploited. Waste water is increasingly
being treated to supply non-drinking water, but it still cover a small proportion of the demand.
Desalination of sea water is the main source of potable water in UAE, but the high economic cost
of desalination, its intensive energy demand and the adverse effects of its effluents on the marine
life are a major concern. Other factors contributing to the problem are the focus of water
management policies on keep supplying the growing demand for water, the increase of the per
capita water consumption, and the free water charge for most of population.
This research goal is to develop a water sustainability set of indicators for the challenging
context of UAE. This paper presents the first stage of the research. Based on a review of the
literature, the proposed framework involves 19 indicators, divided into four categories: water
availability; water quality; water use efficiency; and policy and governance. Using an integrated
cause-effect approach (DSR – Driving force, State, Response), the indicators were related in
terms of their interdependencies, with a holistic view of the city water cycle.
A preliminary test of the indicators to Abu Dhabi as a case study allowed an evaluation of the
main ‘Driving force’ on the system, such as the scarcity of water due to natural constraints of the
region, and increasing water consumption patterns of modern society; an assessment of the
current ‘state’, which is under serious water stress. Also it indicated some potential ‘responses’,
such as implementing policies for increasing efficient use.

Introduction
According to United Nations World Water Assessment Programme (WWAP), Water represents a
global challenge for the 21st century, in the management of available water resources and the
provision of access to drinking water and sanitation (UN 2010). In January 1992, a group of
environmental expert met in Dublin, on Water and the Environment conference and called for
new approaches to the assessment and management of water resources (UN 1992). The outcome
of this conference was the Dublin statement on water and sustainability development with four
guiding principles, which are principle “Fresh water is a finite and vulnerable resource, essential to
sustain life, development and the environment” , “Water development and management should be based
on a participatory approach, involving users, planners and policy-makers at all levels ” Women play a
central part in the provision, management and safeguarding of water” and the fourth principle is
“Water has an economic value in all its competing uses and should be recognized as an economic good” . The
UN Conference on Environment and Development (UNCED) in Rio in June 1992, recommend
countries to apply Dublin principle and transfer it to action plan to manage their water resources.
Agenda 21 chapter 18 stated that “integrated water resource management is based on the
perception of water as an integral part of the ecosystem, a natural resource and a social and
economic good, whose quantity and quality determine the nature of its utilisation” (UN 1992).
The purpose of this paper is to develop water sustainability index for Abu Dhabi Emirate.
The developed indicators can provide reliable guidance to decision making. The paper consist
reviews the city practice in water aspect, methodology, development of Abu Dhabi water index
result and discussion.
Water crises in Abu Dhabi (UAE)
Abu Dhabi Emirate is the capital of the United Arab Emirates. It has a population of 2,120,800 in
2011and occupies an area of 67,340 km², comprised of three regions: Abu Dhabi, Al Ain and Al
Gharbia (Figure 1).

Figure 1: Abu Dhabi Emirate.
The Abu Dhabi Emirate faces serious problem related to the water resources, both in
terms of supply and demand. The emirate has a very dry climate with low rainfall and high
evaporation rate, which results in scarcity of water availability. At the same time, Abu Dhabi has
one of the highest per capita water consumptions in the world.
Mekonnen in 2011 studied the world water footprint, estimating the annual per capita
water consumption for different countries. Figure 2 shows the average water footprint in the
world between1996 and 2005. The world’s average water footprint is 1,385 m³/yr. Countries
shown in green in Figure 2 have a water footprint that is lower than the global average, and
counties in yellow-to-red have a water footprint larger than the global average (Mekonnen 2011).
UAE water footprint is one of the highest in the world: 3,136 m³/year/capita. In comparison, the
water footprint of USA is 2,842 m³/year/capita, and the water footprint of Australia is 2,315
m³/year/capita (Mekonnen 2011).

Figure 3 shows a map of water availability in the world according to the study developed
by Falkenmark et al. (2009). Countries shown in green have no stress in water availability, while
countries in yellow have water scarcity, and the countries in red, like UAE, have an extreme
water scarcity.
Figure 3: Fresh water availability by county. Source (Falkenmark, Rockström et al. 2009)
Abu Dhabi Emirate use water from three main resources: ground water (64%), treated
sewage effluent (7%), and desalination (29%). The situation of each of these sources is described
below.
5

Groundwater
According to the Environmental Agency in Abu Dhabi, groundwater levels have been
extensively lowered due to overexploitation of ground water, mainly for agricultural purposes,
and to decreased rainfall. Abu Dhabi Emirate groundwater’s resources are almost non-
renewable, due to the very low recharge and high consumption rates. Moreover, The Ground
Water Assessment Project (GWAP) estimated that 7% of the ground water in the Emirates is
fresh and 93% is brackish water. Natural groundwater renew accounts only for 300 million
m³/year (Dawoud 2008). On the other hand, groundwater withdrawals total over 3,400 million
m³/year (Dawoud 2008). This is a serious problem, since ground water sources supply
approximately 64% of the water consumption on the UAE (Dawoud 2012).
Agriculture is the main consumption sector of groundwater. Domestic groundwater
consumption is very small, because of declining water quality and increased pumping cost of
groundwater (Pitman, Donnell et al. 2009).
Treated sewage effluent (TSE)
The emirate owns 28 sewage treatment plants, within a treatment capacity of 430,000 m³ of
sewage each day per plant (EA 2006). The sources of wastewater are mainly from domestic,
industries, and rainfall. The total wastewater generated is 219.6 m³/year, and it has a high
standard of quality (Absal 2009). Treated sewage effluent contributes to 7% of the total water
demand in the Emirate (Dawoud 2012). The government use 60 % of treated wastewater for
urban landscaping irrigation and plantation purposes only, while 40% discharge to Environment.
Desalination
In Abu Dhabi emirate there are eight seawater desalination plants, with a capacity around 742
Million m³/year. Water from desalination plants accounts for 29% of the water demand.
Seawater desalination, however, presents some problems. First, the cost of sea water desalination
is extremely high. Second, it is an intensive energy consuming process to run (Dawoud and
Mulla 2012). In addition to that, effluents from the desalination process adversely affect marine
life, especially in vicinity of the treatment plants (Areiqat and Mohamed 2005).
These are of concern, since desalination presents trends to increase in the future as a
source of water in Abu Dhabi. The growth in desalination water demand in different region in
Abu Dhabi emirate from 2009 to 2011 is elaborated in Figure 4. Abu Dhabi city demand 62% of
6

total desalination followed by Al Ain region by 27 % than Al Gharbia with 11 % (Dawoud
2008).

Methodology
This section presents the process for developing Abu Dhabi city indicators related to water
sustainability. There are several approaches and frameworks for developing indicators. The
present study has adopted the PSR (Pressure, State, and Response) framework. It considers that
pressures (human activities, population growth, climate change, etc) effect on the environment,
changing its state (quality and quantity of natural resources, for example), and that society
responds to these changes (through policies or new behaviour, for example) (PlanBleu 2010).
This framework was chosen because the study aims not only to use indicators to assess
condition, but also to monitor change, and to provide indication of potential responses to mitigate
or solve identified issues.

Figure 5: Methodology for building city water index
Figure 5 illustrates the methodology for building Abu Dhabi water index .The first step,
presented briefly in the previous section of this paper, involved an evaluation of the current state
of the Abu Dhabi city. Following this, an initial list of selected indicators was created based on
literature review. The following criteria has been considered in the selection of good
sustainability indicators: an indicator should be relevant to the problem addresses; it should
reflect changes in management and activities over time and space; it needs to provide reliable
information; it have to be based on accessible data; and it must be integrative, allowing
connection between environmental, social and economic aspects of sustainability (Brandon and
Lombardi 2005; UN-HABITAT 2006; Chaves and Alipaz 2007; Juwana, Muttil et al. 2012; Van
Leeuwen, Frijns et al. 2012).
The list of pre-selected indicators from the literature review was then filtered based on its
relevance and viability to the specific context of Abu Dhabi. Indicators that are not related to
UAE environment were excluded from the list. Also if there were no satisfactory information
available to measure an indicator, it was excluded from the list. A complex step in this process
was to define the scale for the proposed indicators to evaluate the city performance. The scale

was defined by benchmarking each indicator in relation to performance in different countries
reported in the literature.
Table 1 presents the result from this process. It lists the selected indicators related to
water sustainability for the Abu Dhabi City, divided into four dimensions: water availability,
water quality, water use efficiency, and policy and governance. Each indicator is described in
terms of its scope, unit of measurement, position in the PSR framework, scale based on
benchmarking, available data for Abu Dhabi, and a preliminary qualitative score indication, and
references in which the data or concept is based. These indicators are discussed in the following
section.

Abu Dhabi Water Sustainability Index (ADWSI)
There is no clear set of sustainability indicators to evaluate urban water (Van Leeuwen, Frijns et
al. 2012). The developed indicators in Table 1 covered the main water challenges and concerns
in Abu Dhabi emirate, which are the following:
Water availability
According to Falkenmark (2004) ideally a person needs as much as 1,700 m³ of water/year to
support life, while below 1,000 m³/person/year water availability becomes scarce. The minimum
requirement is 500 m³ of water/person/year, and below this level the water will be extremely
scarce (Falkenmark and Rockstrom 2004).
Water quality
Water quality is a state indicator that usually refers to the physical, chemical, biological and
organoleptic properties of the water (UN 2010). Water quality is calculated by concentration of
chemicals and microbiological criteria and based on Abu Dhabi Water Quality Regulations 2009
and international standards such as World Health Organization standards WHO. In this study we
assessed the quality of ground water, drinking water and sea water as below:
Drinking water quality: Desalinated sea water is the main source of potable water in the
area. It is very important to evaluate the quality of water for safe human drinking if it meets
international standards. Abu Dhabi standard is aligned with international standards as illustrates
in Table 2 compares the Abu Dhabi Water Quality Regulations with the WHO drinking water
guidelines for the European Union (EU) and the United States standards (USEPA).

Ground water quality: pollution of groundwater mainly from large use of inorganic
fertilizers. To manage the Nitrogen concentration this indicator has selected as the quality
parameter for ground water. Water Quality Index in Environmental Performance Index 2010
calculated the target for total Nitrogen (N) is 1 μg/l (YCELP and CIESIN 2010). Secondly,
Salinity is described in terms of the concentration and state of the material present in the water,
together with certain physical characteristics of the water (Bartram and Ballance 1996). Salt
enter ground water naturally through dissolution of soil and through human such as irrigation,
fertilizers, manures and wastewater treatment (GAMA 2010). The Salinity level increase sharply
in western region in Abu Dhabi Emirate (Dawoud 2008). Increase in salinity of ground water
leads to increase the amount of dissolved material in water such as Nitrate and Boron (Dawoud
2008), so this indicator is critical for the area since it was selected. According to California
Water Resources Control Board the natural value of TDS in ground water is 100 to 50,000 mg/l
(GAMA 2010).
Sea water quality: Sea water quality is critical for marine life and the environment, as
mentioned previously; desalination effluents affect seriously the quality of sea water, particularly
by increasing the temperature of the water in the surroundings of desalination plants.
The proposed indicators for the quality of sea water are related to Salinity, and concentration of
Copper and Chlorine. These indicators increased in the study area as a result discharge high
concentration of salt in sea daily. The USA Environmental Protection Agency (EPA)
recommends that the salinity variation from natural levels should not exceed 4 units (Cipollina,
Micale et al. 2009). Moreover, U.S EPA recommendation for Copper concentration in the sea
water is 4.8 μg Cu/l for brief exposure and 3.1 for long exposure, and Chlorine at long-term
criterion 7.5 μg/L and a short-term criterion of 13 μg/L (Cipollina, Micale et al. 2009; EPA
2012). In addition, sea water temperature is another key indicator. Changes in the temperature of
sea water may affect many parameters such as the amount of dissolved oxygen in the water. The
average temperature of the Gulf Sea is 35 degrees Celsius (°C) in summer. Desalination plants
raise the temperature level of the water in its vicinity by about 7 to 8 °C above the ambient
condition (Dawoud and Mulla 2012) .
13

Water use efficiency
These indicators measure the efficiency of the use of water for different purposes, including
water consumption and reuse. According to the World Meteorological Organization (WMO)
high degree of over subscription is indicated when the water use is more than 40% of available
resource (WMO 1997; Juwana 2010; YCELP and CIESIN 2010).
The selected indicators show the pressure in water consumption, both within sectors and across
users. In other hand they show the response which is the percentage of total wastewater treated
and reused. According to the Asian Green City Index, the average wastewater treatment is 60%
for main cities in Asian, while Tokyo treats all of its wastewater (Boselli, McGranahan et al.
2011).
To evaluate the sewage network coverage, percentage of dwellings connected to the
sewage system was proposed. The indicator is important for assessing city health that controls
the possibility of diseased approach from the wastewater. Europe Green water Index Scored
against an upper benchmark of 100% and a lower benchmark of 80%(Shields and Langer 2009).
Another important proposed indicators “Percentage of Water Leakage”, this indicator
measure the water lost during the distribution cycle. According to Asian Green City Index The
average water leakage rate in Asian cities is 22%. Asian Index benchmark scoring Zero-max;
lower benchmark of 45% inserted to prevent outliers (Boselli, McGranahan et al. 2011). On
other hand, the average water leakage rate in Europe at about 23%, and the index scoring upper
target of 5% (Shields and Langer 2009).
Policy and governance
These indicators provide a clear image of government mechanism to manage city water, to
achieve sustainability and keep an eye on environmental performance, these include enhance
water quality, improve water use efficiency, regulate different laws, participation of residents in
environmental decisions.
Result & Discussion:
Indicators based analysis is a very powerful approach, this section shows the Abu Dhabi
performance based on the developed indicators.

Applying Driving force –State–Response (DSR) approach, helped to identify the type of the
pressures from consumption of water, the state of the quantity and quality of city and the city
response to measure reaction to protect the water as shows in Table 3.

Water availability
Water resources in Abu Dhabi, needs more concern from different stakeholders. Abu Dhabi
Emirate had only 18,000 Mm³of fresh water almost not renewable (Dawoud 2008). The total
population in the emirate in 2010 is 2 million and expect to increase sharply (SCAD 2010); Per
capita fresh renewable water availability is almost nil per person, considering natural renewable
water sources, hence Abu Dhabi scored below 500 which is extremely scarce.
According to Abu Dhabi Environmental Agency (2012), Groundwater supply is decreasing and
the difference between supply and demand is being filled by increasing amounts of desalinated
seawater. The capacity of the Emirate desalination plants is increased while the capacity of
ground water is decreased and the amount of treated sewage effluent is still small compared to
other sources of water, and needs to be enhanced.
Quality of water
Drinking water in Abu Dhabi Emirate is mainly from desalination sea water. Abu Dhabi
Distribution Company ADDC tests the samples for 64 parameters categorized into 7 groups,
classified as follows: Physical, Inorganic Chemical, Inorganic Trace Elements, Organic,
Microbial, Radioactive and Disinfection & Disinfection By-Products. In 2011 the total
15

parameters tested were 65,432 and the total numbers of samples taken were 3,046, the
percentage parameters compliance in 2011 was 95% (Ghoussaini 2012).
Sea water Quality (μg/l), specific in desalination plant vicinity, needs more attention
from stockholders. The concentration level of “Salinity”, “Copper” and “Chlorine “exceeded
the natural sea water level. The salinity of the sea water in the area is about 45 ppm and the
desalinated of seawater increases this level by about 5 to 10 ppm (Dawoud and Mulla 2012), the
U.S EPA recommends this should not exceed 4 units(Cipollina, Micale et al. 2009). According
to El Din (2007) the multi stage desalination plant containing some 0.2-0.25 ppm of residual
chlorine, is continuously discharged to seawater(El_Din 2007). Furthermore, the gulf sea average
temperature is 35 °C, desalination plants increase in the temperature level in its vicinity by about
7 to 8 °C above the ambient condition(Dawoud and Mulla 2012). The high salinity and
temperature of desalination plant lead to increasing the concentration of Dissolved Oxygen in
plant vicinity which is reported in some area more than 5μg /l while the standard is <4 5μg
/l(Areiqat and Mohamed 2005; Dawoud and Mulla 2012) .
Ground water quality also needs more attention. The level of concentration of Nitrogen
include both (Nitrate+ Nitrite) ranged between 5 -80ppm (EA 2008), far away from Water
Quality Index. Salinity of ground water Concentration parts per million (ppm) or μg/l ranged
between 300 - 70,000 (EA 2008). While the natural value of TDS in ground water is 100 to
50,000 mg/l (GAMA 2010).
Water use efficiency
Abu Dhabi Emirate used about 4300 million cubic meter per year either from natural resource,
treatment or desalination water, although it had almost no fresh renewable water as discussed in
earlier. Abu Dhabi Emirate extremely under stress. According to environmental performance
report in 2010 UAE ranked number 142 in Water Stress index (2010) with score of 10.5 out of
100 (YCELP and CIESIN 2010).
Abu Dhabi has one of the highest water consumption rates in the world. According to
Abu Dhabi Statistic Centre 2012 water consumption rate in Abu Dhabi increased from 800 litters
/person/day in 2001 to 1300 litters / person/day in 2011 the figure include both domestic and
16

industrial, Likewise, domestic water consumption increased from 350 litters /person/day in 2003
to 550 litters / person/day in 2008, although the natural water resources in UAE are limited as a
result of tiny amount of rain, Figure 6 shown the growth in water consumption compared to
world average from 2001-2011.
Figure 6: Abu Dhabi water consumption compared to world average Source Abstract form (SCAD 2012)
Relatively the free water charge has played a critical role in increase the water demand
especially domestic. Water consumption in Vila (2 floors house) is higher three times than the
apartments, where the average rate in the apartment is 165 litters per day, these because of
consuming more water in irrigate gardens, swimming pool and washing cars. Water consumer in
Abu Dhabi Emirate benefit from the government high subsidies, local citizens consume water
free of charge. Other consumers such as foreign residents, farmer and industrial users are
charging for a small amount for water consumption which is 2.2 AED per cubic meter (≈0 .6
US$).
Percentage of dwellings connected to the sewage system in Abu Dhabi is almost 95%
which is very good compared to Europe Green water Index Score an upper benchmark of 100%
and a lower benchmark of 80%.
Local citizen account 22% from total population, the local citizen benefits from government
subsidies 100%, other hand 78% of the total population paying for water usage, pay about 29%

of actual cost(RSB 2009). The government should review the water legislations and prices,
applying reasonable water usage price (Tariffs) can be one solution to cut the water demand.
Policy and governance
To measure public participation in city water management activities keys issues has been
selected as illustrates in Table 4, the total items of positive answer = 1 out of 6, as a result the
percentage of public participation in water activities in Abu Dhabi Emirate is only 2 out of 10 ,
which needs more attention. One initiative of Abu Dhabi government associated with WWF is
Hero of the UAE as a part of large campaign to reduce water and energy use. This kind of
campaign must be complete and sustained campaign targeting all community members, not just
at period as the case above.

Abu Dhabi government is making great efforts to manage city water, despite the life
style, culture and behaviour which are fundamental issues affecting significantly the habitual
consumption of local citizen. Policy makers in Abu Dhabi Emirate must put more effort to
review the city demand pattern rather than supply; further examination of current consumption
practice can save city resource.
Seeking sustainability is a long term agenda, long term public education is a useful tool
starting from school education, public awareness, furthermore enforcement of legislation can
help city to adopt better strategies to manage their water resources.
Conclusion
This paper proposed water index to evaluate sustainability of Abu Dhabi emirate. It discussed the
water problems and challenges in the area, and compared the city’s performance to the world.
The water index seeks to understand and derive knowledge in a given local environment. The
major goal of indicators is to assess sustainable development of the city’s water. The information
provided through built indicators can be used to evaluate, monitor, manage and enhance the
19

city’s environmental sustainability by providing comprehensive and analysis of city’s
performance.
the limitation in the study is that the selected components and indicators were based on
concern issues in the area and availability of the information, with more information especially
about the infrastructures of water system and water quality (marine and groundwater), these may
lead to find more alternatives that can add from the proposed list and further development is
important issue. However indicators should be a guide to best decision making of the city’s
sustainability; measures the achievement of strategies, policies and developmental programs
related to a specific water issue. Moreover it provides decision makers with full and
comprehensive information about the current city’s performance; it can be used to evaluate water
resource in different places across different period, represent water supply and demand analytical
issues which constitutes a critical factors for Abu Dhabi city. It also increases the local people’s
understanding of the reality of the city’s performance and how it affects the future.
