“…In this context, Stefano & Gunn (2012) pointed out that groundwater is likely to play a pivotal role in facing water scarcity in many areas of the world, particularly in arid regions or in areas experiencing population growth. This is likely to increase in the future due to continued population growth, urban expansion and the expected challenge in the form of climate change impact on water resource availability.…”

Spatial variation in irrigation demand and supply across canal commands in Punjab: a real integrated water resources management challenge

2013

The Indus Basin Irrigation System (IBIS) is more than a century old. Water allowances and canal water distributions responded to increasing crop water requirements in a southward direction, e.g. higher water allowance in Sindh as compared to Punjab. But within a province, the canal water supplies do not address the issue of difference in irrigation demand. The consequence is unprecedented groundwater depletion in Bari Doab and waterlogging in certain other canal commands. After the Indus Waters Treaty of 1960, gradually reduced flows and ultimate desiccation of eastern rivers have also contributed towards falling groundwater levels of adjoining aquifers. In this study, water allocations in the Water Apportionment Accord of 1991, annual average canal water diversions, and irrigation demand were compared for canal commands in Punjab. Rainfall was taken as an ultimate source of water that has a beneficial impact in integration with canal and groundwater. It is concluded that the efficiency of existing irrigation systems can be improved by adopting the concept of integrated water resources management (IWRM). Thus, to avoid waterlogging and groundwater depletion, reallocation of canal water supplies amongst the irrigation units in Punjab, in proportion to the relative irrigation water demand and cropping intensities, is recommended.

“…In order to cope with the current groundwater development anarchy, it is increasingly important to analyze the 30-year experience of groundwater govemance in depth, something which is now the focus of a new Global Environmental Facility project (GEF, 2011). Although there are commonahties between surface and groundwater irrigation govemance, there remain significant differences (De Stefano & López-Gunn, 2012). In this context, a deeper understanding of groundwater govemance and incentive stmctures is needed, as well as an appreciation of where the complementary use of other tools, like information technology and transparency principles, can help to guarantee that the potential benefits of groundwater for water and food security are realized in an equitable manner for both people anci nature.…”

IIn the past two decades, the world has experienced deep changes in terms of globalization of goods and people, the emergence of new economic powers, political turmoil, and a sustained growth of an increasingly urban global population. These and other factors have deep implications for global water and food security, and make discussion of ethical values -often implicit in global debates -more pertinent. An understanding of the ethical issues underlying water and food security is key to formulating solutions that truly contribute to their achievement. This is particularly true when considering that water and food security is strongly intertwined with human security and environmental security, and these cannot be addressed separately. This paper argues that solving water and food problems is not only a technical challenge but also a problem of fundamental ethical values and political will. It showcases three technological advances (desalination, informatioti technology, and modem groundwater abstraction technology) and one concept (virtual water) that could contribute to secure water and food for a growing population, thus shedding light on the lack of concerted political will to face global and water food securities. In this context, trade ha.s the potential to help countries manage water security in a globalized world, provided that global trade is revisited and undergoes a process of deep reform in the light of ethical con.siderations. Water and food are not isolated from general socio-economic and political U-ends, Therefore the drivers resulting in the present economic crisis also affect water and food, and add further complexity to the search for solutions.

“…However, unplanned groundwater use disrupts the natural feeding balance of aquifers. Excessive use of aquifers could have adverse consequences on the environment, ecology, and economy of the region [4,5]. For this reason, groundwater-discharge zones need to be determined with a focus on appropriate water management.…”

The Tigris River Batman-Hasankeyf region sub-basin drainage area is in the Upper Tigris basin and lies between the area where the Batman stream joins the river and the Yanarsu stream flows into the river. Intensive agricultural activities are carried out in this region, and irrigation is generally obtained from groundwater just as it moves away from the riverfront. The study area is a valuable basin for both Turkey and the Middle East. In this study, the effectiveness of the Geographic Information System (GIS)-based multicriteria decision-making (MCDM) analytic hierarchy process (AHP) as a spatial prediction tool was utilized in exploring the groundwater potential of the drainage area. In the analysis, eight hydrological and hydrogeological criteria were considered as influencing factors, namely, geomorphology, geology, rainfall, drainage density, slope, lineament density, land use, and soil properties. The weights of these criteria were determined through the AHP method; the Arc GIS 10.2.2 program and its submodules were used. The major findings of the study were that groundwater-potential index values of the basin were derived. Groundwater-potential-zone evaluation of the basin was obtained as follows: very poor (19%), poor (17%), moderate (34%), good (17%), very good (13%); and groundwater potential zone (GWPZ) maps of the sub-basin were created. 2 of 16 model [8]. Most of these methods are based on multivariate statistical techniques [9]. In contrast, the analytical hierarchy process (AHP) is considered to be a simple, effective, transparent, and reliable technique [10]. The AHP method is easy to identify in a useful way by integrating geographic information system (GIS) and remote sensing (RS) data. Groundwater parameters such as precipitation, aquifers, land use, and soil type can easily be defined as spatial data in a GIS environment. Thus, the method is very useful for identifying potential groundwater areas and is well-suited for the useful identification of groundwater-potential regions [11][12][13]. AHP is an approach that was developed by Thomas L. Saaty in the early 1980s [14]. It was developed with planned criteria according to a certain stage, evaluating the weights of these criteria, and comparing the criteria with other similar studies [15,16]. It is possible and preferable to determine hydrological and hydrogeological parameters that influence groundwater formation and their effects on groundwater formation and generate potential groundwater maps with GIS-based Multicriteria Decision-Making (MCDM) techniques. GIS-based multicriteria decision analysis (MCDA) has been extensively used in the field of hydrological and water resources [16,17]. It has gained popularity in the last decade as it provides GIS-based mapping [18].Most current studies [19][20][21][22] widely applied RS-and GIS-based AHP-MCDM techniques for the assessment of Groundwater Potential Zones (GWPZs) with effective results. When these studies were examined, it was found that land use (LU), geomorphology (GM), geology (G), recharge...
