Groundwater development across much of sub-Saharan Africa is constrained by a lack of knowledge on the suitability of aquifers for borehole construction. The main objective of this study was to map groundwater potential at the country-scale for Ghana to identify locations for developing new supplies that could be used for a range of purposes. Groundwater potential zones were delineated using remote sensing and geographical information system (GIS) techniques drawing from a database that includes climate, geology, and satellite data. Subjective scores and weights were assigned to each of seven key spatial data layers and integrated to identify groundwater potential according to five categories ranging from very good to very poor derived from the total percentage score. From this analysis, areas of very good groundwater potential are estimated to cover 689,680 ha (2.9 % of the country), good potential 5,158,955 ha (21.6 %), moderate potential 10,898,140 ha (45.6 %), and poor/very poor potential 7,167,713 ha (30 %). The results were independently tested against borehole yield data (2,650 measurements) which conformed to the anticipated trend between groundwater potential and borehole yield. The satisfactory delineation of groundwater potential zones through spatial modeling suggests that groundwater development should first focus on areas of the highest potential. This study demonstrates the importance of remote sensing and GIS techniques in mapping groundwater potential at the country-scale and suggests that similar methods could be applied across other African countries and regions.

Surface and groundwater resources are often conjunctively used to cope with water scarcity in irrigated agriculture. Farmers in the dryland ecosystems of central Asia also utilize shallow groundwater in addition to surface water withdrawn from rivers. This study modelled groundwater dynamics in an irrigation and drainage network in Khorezm region, Uzbekistan. The system, characterized by a vast, unlined channel network used to convey water mainly for flood irrigation and an open drainage system, is typical of Central Asian irrigated areas. Groundwater levels in the region are shallow—this contributes to crop water requirements but threatens crop production through secondary salinization. High losses during irrigation in fields and through the irrigation network are the main causes of these shallow groundwater levels. The main objective of this study was thus to simulate groundwater levels under improved irrigation efficiency scenarios. The FEFLOW-3D model, applied in a case study to the water users’ association (WUA) of Shomakhulum in south-west Khorezm, was used to quantify the impact of improved irrigation efficiency scenarios on groundwater dynamics. The modelled scenarios were: current irrigation efficiency (S-A, our baseline), improved conveyance efficiency (S-B), increased field application efficiency (S-C), and improved conveyance and application efficiency (S-D). Recharge rates were separately determined for six hydrological response units (differing in groundwater level and soil type) and introduced into the FEFLOW-3D model. After successful model calibration (R2 = 0.94) and validation (R2 = 0.93), the simulations showed that improving irrigation efficiency under existing agro-hydroclimatic conditions would lower groundwater levels from the baseline scenario (S-A) in August (the peak irrigation period) on average by 12 cm in S-B, 38 cm in S-C and 44 cm in S-D. Any interventions which would improve irrigation efficiency will lower the groundwater levels and hence policy makers should consider them and formulate the policy accordingly.

We develop conceptual and numerical models of water table dynamics under a subsurface irrigation and drainage system. The numerical model is implemented with distinct drainable and fillable porosity parameters that are estimated by accounting for the unsaturated zone fluxes to and from the shallow water table. The model was applied to two field sites under subsurface irrigation and drainage system in northeast Florida to simulate water table dynamics during potato growing seasons in 2010 and 2011. Simulated water table elevations showed a close agreement with the observed water table dynamics in the fields during both growing seasons. Furrows that act as shallow drains in the field facilitated rapid drawdown of the water table after rainfall events, while the outer, deeper ditches provided little drainage of water from the root-zone. Intermittent irrigation regimes, although could substantially reduce surface runoff from the fields, resulted in relatively deeper water tables during the growing season, suggesting a potential trade-off between water deliveries and root-zone soil moisture availability.

The top priorities for urban water sustainability include the provision of safe drinking water, wastewater handling for public health, and protection against flooding. However, rapidly aging infrastructure, population growth, and increasing urbanization call into question current urban water management strategies, especially in the fast-growing urban areas in Asia and Africa. We review innovative approaches in urban water management with the potential to provide locally adapted, resource-efficient alternative solutions. Promising examples include new concepts for stormwater drainage, increased water productivity, distributed or on-site treatment of wastewater, source separation of human waste, and institutional and organizational reforms. We conclude that there is an urgent need for major transdisciplinary efforts in research, policy, and practice to develop alternatives with implications for cities and aquatic ecosystems alike.

Treated wastewater resource is underexploited in Cebala’s Irrigated scheme (Northern Tunisia) and farmers are reluctant to reuse it. The delimitation of the irrigated area will help enhance the global economic profitability of the perimeter not only by reducing the operation and maintenance costs but also by optimizing the reuse activity according to the farmers’ demands, their aspirations and aims. Thus, the aim of this paper is to consider reducing the surface of the irrigated area, keeping only the parcels where the resource is highly demanded. A spatial data analysis using a multicriteria decision technique (compromise programming—CP) and a geographical information system was carried out to choose the best scenario. To this end, five zones where breeding activity is well developed and the non-conventional resource highly demanded were identified as the closest delimitations to the ideal solution. The Compromise programming method was used to rank these solutions. Finally, a surface of 2485 ha was identified as the best delimitation scenario, corresponding to the area where breeding activity is well developed.

This review paper intends to portray current scenario of agricultural productivity through yields and gaps of five major crops; wheat, cotton, rice, maize and sugarcane. The review discusses major constraints, identifies future prospects and makes policy recommendations for enhanced agricultural productivity in Pakistan. The review revealed that in Pakistan, on average current yield of wheat, cotton, rice, maize and sugarcane is 2.26, 1.87, 2.88, 1.77 and 48.06 tons per hectare, respectively against 6.80, 4.30, 5.20, 9.20 and 300 tons per hectare potential yield of wheat, cotton, rice, maize and sugarcane, respectively, obtained through research. This reflects a yield gap of 67, 57, 45, 81 and 84 % between average and potential yield of wheat, cotton, rice, maize and sugarcane, respectively. The review also informed that current Pakistan’s average yield of wheat, cotton, rice, maize and sugarcane is 70, 53, 61, 82 and 60%, respectively lower than the average yields obtained internationally. Major constraints include agronomic, irrigation management, environmental, technological, institutional and socio-economic constraints. Future prospects include upscaling of modern technology, enhanced seed production, improved inputs availability and use, improved irrigation, improved agriculture-education-training-research- extension-nexus, reclamation of salinized lands, improved agricultural credit and support price policies. Recommendations include improving agricultural research and extension systems, accelerating diffusion and adoption of latest agriculture technologies and inputs, enhancing good quality seed production, improving irrigation water management and improving reclamation and drainage.

Presently, the water resources across the world are being continuously depleted. It is essential to find sustainable solutions for this shortage of water. Rainwater harvesting is one such promising solution to this problem. This paper presents a new GIS-based methodology to identify suitable locations for rainwater harvesting structures using only freely available imageries/remote sensing data and data from other sources. The methodology has been developed for the semi-arid environment of Khushkhera-Bhiwadi-Neemrana Investment Region (KBNIR) in Alwar district of Rajasthan. For identifying locations suitable for rainwater harvesting structures, the layers of surface elevation (ASTER-DEM), landuse/landcover, soil map, drainage map and depression map are used and further analyzed for their depression volume, and availability of surface runoff using Soil Conservation Service - Curve Number (SCS-CN) method. Based on the proposed criteria total seven locations were identified, out of which two locations are excellent; three locations are good, (if provisions of overflow structure are made for them) and two locations are not suitable for rain water harvesting. The total rainwater harvesting potential of the study area is 54.49 million cubic meters which is sufficient to meet the water requirements if harvested and conserved properly. This methodology is time-saving and cost-effective. It can minimize cost of earthwork and can be utilized for the planning of cost effective water resource management.
