Developing GIS-based water poverty and rainwater harvesting suitability maps for domestic use in the Dead Sea region (West Bank, Palestine)

Sameer M. Shadeed, Tariq G. Judeh, and Mohammad N. Almasri

In the arid region of the Dead Sea, water shortage and the inability to satisfy the increasing domestic water demand threatens sustainable development. In such situations, domestic rainwater harvesting is considered an efficient way to combat water poverty. This paper aims to develop domestic water poverty (DWP) and domestic rainwater harvesting suitability (DRWHS) maps for the West Bank, Palestine. The analytical hierarchy process (AHP) and the GIS-based weighted overlay summation process (WOSP) were utilized in the development of these maps. Results of the DWP map indicate that 57 % of the West Bank is under high to very high poverty of domestic water. The DRWHS map shows that 60 % of the West Bank is highly suitable for domestic rainwater harvesting. Spatial intersection (combined mapping) between DWP and DRWHS maps indicates that around 31 % of the total West Bank areas could be classified as high potential locations (hotspot areas) for adopting rainwater harvesting techniques for domestic purposes. The developed maps are valuable to the stakeholders to better identify the best areas of rainwater harvesting in the West Bank.

1 Introduction

Water is a key factor for sustainable development. In the 21st century, the main challenge for millions of people worldwide is the lack of access to safe and clean water for domestic purposes (Worm and Hattum, 2006). In the West Bank (Palestine), water shortage is a problem that jeopardizes the sustainability of water availability for different uses (PWA, 2011). This situation deteriorated further due to the population growth and climate change that imposed a tremendous stress on the conventional water supplies (PWA, 2011). The existing political situation limits the Palestinians' accessibility to their water resources, and this further deepens the water problems (Judeh et al., 2017). In 2015, the estimated annual water supply–demand gap for domestic purposes for the entire West Bank was 32 million m3 (MCM) (PCBS, 2015).

DWP (domestic water poverty) is a term that describes the competency of water service providers to constantly provide customers with clean, sustainable and affordable domestic water (Feitelson and Chenoweth, 2002). It is measured by using an index called the domestic water poverty index (DWPI) (Sullivan et al., 2003). The DWPI can be attributed to several factors associated with water availability, socio-economic conditions, environmental implications and the political situation (Coppin and Richards, 1990; Sullivan et al., 2003). DWP mapping is a simple and efficient approach to identify the spatial extent of water-poor/rich areas at different levels of jurisdiction areas (Thakur et al., 2017). This approach has been applied in the analysis of water stresses in many countries all over the world such as the US (James et al., 2007), Nepal (Thakur et al., 2017) and Palestine (West Bank) (Isaac et al., 2008).

A DWP map has several pros as it demonstrates the relationship between the physical availability of water, its quality and suitability for domestic use, and its accessibility. It is also a tool for monitoring programs in the water sector, and it helps in improving the situation of communities that suffer from water poverty (van der Vyver and Jordaan, 2011).

Generally, water-poor areas should look for new, safe, sustainable and unconventional sources of water. For instance, rainwater harvesting (RWH) is considered a viable alternative to secure water (Abdulrazzak, 2003). In arid and semi-arid regions, adopting RWH will potentially enhance the economic, environmental and social development under uncertainty of water supply (UNEP, 2009). In Palestine, and given the uncertain groundwater supply, RWH is considered a sustainable option to bridge the increasing domestic water supply–demand gap (Shadeed, 2011).

RWH is the process of collecting and storing rainwater in order to be used afterwards for different uses among which is the domestic one (Gould and Nissen-Petersen, 1999). It is considered an ancient technology dating back to biblical times and was practiced in Palestine and Greece 4000 years ago (Critchley et al., 1991).

The use of RWH for domestic purposes entails that water quality is sufficiently good and within the permissible limits of drinking water quality standards. Mostly, the quality of harvested water can be controlled by proper practices (e.g., cleaning of the collecting surface such as roofs and removing the discharge of the first storm) and simple disinfections techniques when needed (African Development Bank, 2010; Meera and Ahammed, 2018).

In arid and semi-arid regions, domestic water productivity was enhanced by adopting RWH for many years (Boers et al., 1986; Bruins et al., 1986; Critchley et al., 1991; Abu-Awwad and Shatanawi, 1997; van Wesemael et al., 1998; Oweis et al., 1999; Li et al., 2000; Li and Gong, 2002; Rosegrant et al., 2002; Ngigi et al., 2005; Ngigi, 2006; Oweis and Hachum, 2006; Rockström and Barron, 2007; Mwenge Kahinda et al., 2007; Campisano et al., 2017; Singh and Turkiya, 2017; Tamaddun et al., 2018). In the West Bank, RWH is widely used at the household level in rural areas (Shadeed, 2011). About 50 % of the entire West Bank area is classified as suitable to highly suitable for RWH for different uses (e.g., domestic and agricultural) (Shadeed, 2011). RWH is being practiced in the Faria catchment located in the northeastern part of the West Bank, and this helps in bridging the domestic water supply–demand gap (Shadeed and Lange, 2010).

This research aims at mapping the DWP and DRWHS (domestic rainwater harvesting suitability) maps for the entire West Bank. An integrated approach using GIS-based multi-criteria decision analysis (MCDA) was adopted. The MCDA approach is widely used in DWP (van der Vyver and Jordaan, 2011; Thakur et al., 2017; Sullivan et al., 2003; Isaac et al., 2008) and RWH suitability studies (Shadeed, 2011; Galarza-Molina et al., 2015; Hussein and Shariff, 2015; Singh et al., 2016; Singhai et al., 2017; Jha et al., 2014).

The MCDA approach entails that the choice is built on a predetermined and limited number of decision variables (criteria) described by their attributes. Hence, the most influential criteria (layers) that affect both DWP and DRWHS mapping were identified, weighted and scored using AHP (analytical hierarchy process). The AHP approach was adopted by constructing a pairwise comparison matrix to assign relative importance (weight) for each criterion based on a preference scoring scale (Saaty, 1980). The GIS-based weighted overlay summation process (WOSP) was then used to develop both the DWP and DRWHS maps.

A key output in this research is the creation of spatial intersection between DWP and DRWHS maps for the entire West Bank. The developed map identifies the spatial distribution of water needs (water-poor areas) and spatial distribution of the potential of RWH techniques for domestic water use. This in turn can provide the key decision makers with a tool to identify potential locations where the implementation of RWH techniques could be most successful for domestic uses in Palestine.

2 Materials and methods

2.1 Study area

West Bank (Palestine) is located to the west of the Dead Sea. It has an area of about 5860 km2. Administratively, it is divided into 11 governorates with a total population of approximately 2.9 million (PCBS, 2017) (see Fig. 1).

Figure 1Regional setting of the West Bank.


Figure 2Methodological framework for developing DWP and DRWHS maps.


The ground surface elevations range between 1022 m above mean sea level (a.m.s.l.) in the south (in Hebron) and 410 m below mean sea level (b.m.s.l.) in the proximity of the Dead Sea (in Jericho) (UNEP, 2003). The West Bank climate can be generally described as a Mediterranean one, which experiences extreme seasonal variations. The climate varies between hot dry in summer and wet cold in winter with short transitional seasons (Shadeed, 2008). Rainfall shows high spatial and temporal variation, with a long-term annual average of 450 mm, which is equivalent to a rainfall volume of about 2500 MCM (PWA, 2013). Most of the annual rainfall (about 80 %) occurs in winter (Shadeed, 2012).

Water supply for different uses in the West Bank is very limited and does not suffice to satisfy the increasing water demand. The existing political situation adds another constraint on the availability and accessibility of water resources for Palestinians. Water supply is available either from local groundwater wells and springs or purchased from the Israeli water company Mekorot. In 2015, the domestic water supply–demand gap in the West Bank was 65 MCM (PCBS, 2015). Existing DRWH techniques (e.g., rooftops) contributed to about 4 MCM for the domestic use in the West Bank (PWA, 2016).

Under average conditions, the West Bank has high runoff curve numbers with an average value of about 70 (Shadeed and Almasri, 2010). Needless to mention that a high curve number value implies a high runoff generation and this suits the implementation of the RWH techniques.

The land use map of the West Bank is classified into four main classes: rough grazing (62 %), agricultural practices (32 %), built-up areas (5 %) and Israeli settlements (1 %) (MoLG, 2017). The West Bank is characterized by different soil textures such as clay, clay loam, loamy, sandy loam and bare rock covering 47 %, 31 %, 9 %, 8 % and 5 % of the study area respectively (MoLG, 2017). The elevations in the study area ranges from 375 m b.m.s.l. in the vicinity of the Dead Sea in Jericho to 1000 m a.m.s.l. in the mountains of Hebron (MoLG, 2017).

The water poverty index gives the water poverty considering five key components: access, capacity, environment, resource and use (Gould and Nissen-Petersen, 1999). The five key components were represented by 12 influencing criteria (see Table 1). For these criteria, data were collected from different sources which include the Palestinian Water Authority (PWA), Palestinian Central Bureau of Statistics (PCBS) and water service providers (e.g., municipalities). It is worth mentioning that the majority of the utilized data are available at a coarse resolution (e.g., governorate level). In the West Bank, rainwater is being harvested for domestic water supply using different techniques among which rooftops is the most important. Cisterns (pear shaped) and reservoirs are commonly used in the West Bank for storing the harvested rainwater (PWA, 2013). In general, the most influential criteria for DRWH suitability mapping in the West Bank were identified. These criteria are rainfall depth (RD), curve number (CN), surface slope (SS) and land use (LU). The spatial extent of the long-term average annual RD was obtained from the records of the existing rain gauges using the inverse distance weighting method (IDW). The CN map was developed for the entire West Bank (Shadeed and Almasri, 2010). A 25 m×25 m digital elevation model was processed to determine the SS layer. The LU map available at the Ministry of Local Government (MoLG) database was used.

Different weights were assigned for the different criteria used in each map by conducting the AHP pairwise comparison matrix. The matrices were filled using a scoring system (preference values) from 1 to 9 in order to reflect the preference and importance of the criteria (Saaty, 1980) (see Tables 2 and 3).

Once the pairwise comparison matrices were completed, the AHP provides researchers the opportunity to check and enhance the matrices' consistency. However, the matrices' consistency was measured by estimating the consistency ratio using the following formulas (Saaty, 1980):


where CR is the consistency ratio, CI is the consistency index, RI is a random consistency index, λ is a normalized principal eigenvector and n is the number of constraints (criteria).

Figure 3The score rasters of the 12 DWP criteria for the West Bank.


The matrix is consistent if the CR value is smaller than or equal to 0.1; otherwise, it is considered inconsistent and needs to be revised (Saaty, 2000). According to the different preference values used in the pairwise comparison matrices shown in Tables 2 and 3, the CR values for DWP and DRWHS matrices are 0.04 and 0.01 respectively. So, both of them are consistent.

Each of the criteria used in DWP and DRWHS maps were divided into five sub-criteria, and each of them were subjectively assigned a score from 1 to 10 (see Tables 4 and 5). For instance, values which are close to 10 have the highest DWP and DRWHS. Thereafter, rasterization (cell size of 100 m by 100 m) of the different criteria based on their sub-criteria scores was processed by GIS (see Figs. 3 and 4).

GIS is used to estimate DWPI and DRWHSI (DRWHS index) through the application of WOSP for the different layers (criteria) used. WOSP method applies a weighted linear formula in decision-making analysis (Store and Jokimäki, 2003). This method allows the manipulation of various spatial input layers by aggregating the weighted cell values together. Each input layer is multiplied by its assigned weight and the results are summed as (DWPI or DRWHSI)j=i=1nWiSij, where (DWPI or DRWHSI)j is the final cell index, Wi is a normalized weight (Wi=1), Sij is the score of the ith cell with respect to the jth layer and n is the number of cells in each jth layer (Malczewski, 1999).

3 Results and discussion

3.1 DWP map

Figure 5 depicts the DWP map for the West Bank. Using the natural breaks approach, the map was classified into five water poverty categories: very low, low, moderate, high and very high.

Figure 5 shows that the governorates characterized by very high DWP are in the southern (Hebron) and northern parts (Jenin) of the West Bank which have 36 % of the total West Bank population (PCBS, 2017). The Bethlehem, Nablus and Tubas governorates suffer from high DWP conditions. In contrast, the results indicate that the Qalqiliya governorate has the lowest DWP, whereas low to medium DWP conditions are prevailing in the other governorates. However, the area percentages of the different DWP classes in the West Bank are presented in Fig. 6.

Figure 6Area percentages of the different DWP classes in the West Bank.


Generally, the results presented in the previous figure show the domestic-water-poor areas in the West Bank. High to very high DWP conditions cover 57 % of the total West Bank area where 60 % of Palestinians live. Moreover, the areas characterized by moderate, low to very low DWP conditions occupy 43 % of the total West Bank area, which includes 40 % of the total West Bank population. Hence, there is a dire need to look into adaptive and sustainable domestic water alternatives among which RWH would be a successful one to alleviate domestic water shortage in the highly water-poor areas.

3.2 DRWHS map

Figure 7 shows the DRWHS map for the West Bank. As we did before, the map was classified into five suitability categories: very low, low, moderate, high and very high.

Figure 8Area percentages of the different DRWHS classes in the different West Bank governorates.


The developed DRWHS map indicates that the areas characterized as very high are distributed across the northwestern part of the West Bank, except for small portions that are located in the middle and southern mountains. In contrast, the eastern part of the West Bank is classified as very low to low areas. It is clear that the developed DRWHS map is highly influenced by both RD and CN criteria. This is because the trend for rainfall and runoff potential increases in the northwest and decreases in the southeast. The area percentages of the different DRWHS classes in the different West Bank governorates are illustrated in Fig. 8.

In general, about 60 % of the total West Bank area is classified as high to very high for different DRWH techniques. Additionally, it is obvious that the high to very high DRWHS areas are dominant (70 %–95 %) in 6 out of 11 governorates. This indicates the high potential of adopting different DRWH techniques (e.g., rooftop) in trying to bridge the increasing domestic water supply–demand gap in the West Bank.

3.3 DWPM–DRWHSM intersection

The developed DWP and DRWHS maps urged the need to identify zones of high to very high DWP and DRWHS (hotspot areas). Accordingly, spatial intersections (combined mapping) between both maps were accomplished under the GIS environment for four intersection zones. These are very high poverty–very high suitability, very high poverty–high suitability, high poverty–very high suitability, and high poverty–high suitability (see Fig. 9). Results indicate that hotspot areas are located mostly in the northern (Jenin, Tubas and Nablus) and southern (Bethlehem and Hebron) governorates of the West Bank. The area percentages of the four intersection zones are shown in Fig. 10. It is noticed that the four zones equal 31 % of the total West Bank area. Such results can help decision makers to develop sustainable water management options among which proper DRWH techniques is the most important to satisfy domestic water needs predominantly in the identified hotspot areas.

Figure 9DWP–DRWHS map intersection for the entire West Bank.


Figure 10Area percentages of the four intersection zones.


The obtained results were verified using the available data of DRWH activities (digging of cisterns and building of reservoirs) in the middle and northern parts of the West Bank governorates for the period from 1994 to 2017 (PHG, 2018). Results are illustrated in Fig. 11. It is clear that DRWH activities in the last 22 years were concentrated (about 74 %) in the identified hotspot areas in the Nablus, Jenin and Tubas governorates. Thus, the adoption of DRWH techniques (e.g., rooftop) in these areas is of high importance to alleviate water shortage for domestic uses. The DWP and DRWHS combined mapping has several advantages. It is easy to use under the GIS environment, it can be applied at any region in the world once the driving factors (criteria) are made available and it helps decision makers to rely on DRWH techniques as a viable water management option for the benefit of end users in water-vulnerable areas. The method has some drawbacks. For instance, the accuracy of the developed map is highly influenced by the resolution and dynamic changes (e.g., urbanization) of the data. The socio-economic constraints were not considered in this study and need to be studied first in more detail for a realistic implementation of new RWH systems.

4 Conclusions

In this paper, maps of DWP and DRWHS were developed and utilized to identify the suitable locations for the implementation of water harvesting in order to reduce water poverty. The MCDA was employed to account for the influencing criteria according to their importance in the mapping of the DWP and DRWHS. The AHP pairwise comparison matrix approach was adopted to assign the criteria weights. Results show that 57 % of the West Bank is under high to very high DWP. The DRWHS map indicates that high to very high suitable areas are concentrated in the north-western parts of the West Bank. The high to very high DWP and DRWHS areas account for more than 30 % of the total West Bank area and are mostly located in the northern and southern parts. Since the MCDA entails subjectivity in assigning the weights and the scores, it is important to conduct a sensitivity analysis. This can be done by altering the weights and scores and thereafter examining the impacts on the DWP and DRWHS maps. Despite the fact that the available data are limited, this research managed to provide a novel insight towards the identification of high domestic-water-poor areas. This facilitates the implementation of different DRWH techniques that could be successful. This implies the applicability of this research in situations where data are limited. The work furnished herein assists the decision makers to derive proper water management strategies to bridge the gap between the supply and the demand in the West Bank. The results from this study can be applied to the entire Dead Sea region, which undergoes serious water shortage challenges. It is good to consider other spatial analysis levels for the development of the maps like the watershed outlines. Finally, further research is recommended to validate the combined map over different West Bank areas.

Short summary
The paper aimed to develop DWP and DRWHS maps in the West Bank (Palestine) using an integrated GIS-based MCDA approach. The obtained maps will assist the decision makers to formulate proper strategies including the development of efficient and comprehensive water resource management strategies in trying to bridge the increasing water supply–demand gap for domestic purposes in the West Bank as a recognized area in the Dead Sea region which is facing a series water resource shortage challenges.
