The Volta Basin covers 400 000 km of the West-African Savanna. Agriculture is the dominant ecnomic activity. Given the extremely unreliable rainfall, irrigation development is seen as an obvious strategy to increase agricultural production. Irrigation development is mainly linked to the construction of small and medium sized reservoirs. The potential use of groundwater for irrigation is a very important issue. In this study, we present an evaluation of the conjunctive use of surface and groundwater in a representative small reservoir-irrigation system. The physical processes are modelled with WaSiM-ETH. The physical boundary conditions needed for the optimization model are then passed on to the optimization model written in GAMS, which then simulates the capture and utilization of runoff in small reservoirs. Water can be withdrawn for irrigation, or stored. Irrigation water can also be pumped from the underlying aquifer, and pumping costs are modelled as proportional to the distance to the water table.

This paper examines water management policies and institutions in the Ghanaian and Burkinabe portions of the Volta basin of West Africa. The paper begins with a brief historical overview of political, cultural and environmental developments in the basin since the late 19th century. Customary approaches to water management in the Volta are described next, followed by colonial and post-colonial water management developments in Ghana and Burkina Faso. The interplay between customary and national water management institutions in the watershed is then analysed so as to understand how conditions changed as a result of national-level developments. The paper also examines transboundary developments in the Volta basin, and concludes with a discussion of some of the strengths and weaknesses of the different management approaches.

We describe the development, calibration and preliminary application of a dynamically coupled economic–hydrologic simulation–optimization model ensemble for evaluating the conjunctive use of surface and groundwater in small reservoir-based irrigation systems characteristic of the Volta Basin, Africa. We focus on a representative small reservoir irrigation system located in the Antakwidi catchment in Ghana. The model ensemble consists of the physical hydrology model WaSiM-ETH and an economic optimization model written in GAMS. Results include optimal water storage and allocation regimes for irrigated production, given conjunctive surface water and groundwater systems. The goal of our research, conducted within the GLOWA Volta project, is to develop a decision support system for improving the management of land and water resources in the face of potential environmental change in the Volta Basin.

Methods for estimating runoff that have been developed for temperate climates may not be suitable for use in the monsoonal climates of Africa, where there is a distinct dry season during which soils dry out to a considerable depth. This has a distinct effect on runoff generation that is not captured by “the temperate climate” models. The scope of this tool is to develop a simple water balance method for predicting river discharge. Water balance models have been shown to better predict river discharge in regions with monsoonal climates than alternative methods based on the United States Department of Agriculture-Soil Conservation Service (USDA-SCS) curve number. The latter is an empirical-based model developed in the USA that does not apply to monsoonal climates with distinct dry and wet periods.

The limit of rain fed agriculture is one of the major causes for poor agricultural performance in Sub-Saharan Africa, due to the prevailing climatic conditions. If these challenges are further juxtaposed with the climate change projections, irrigation then becomes a key solution to such agricultural challenges of changing rainfall amounts and seasonal rainfall variability in the Upper East region of Ghana. The extreme variability in rainfall, long dry seasons and recurrent droughts, floods and dry spells pose key challenges to food production and has resulted in hunger and poverty in the Upper East Region of Ghana. The practice of irrigated agriculture remains a key solution to hunger and poverty reduction in this area. As a result the area has seen a significant upscaling of irrigation using shallow groundwater and surface water with appropriate technologies within the past 15 years. This study used a gendered approach to assess how poverty alleviation through the use of shallow wells and riverine dugouts have differential access for men and women. Whilst it is often argued that water based interventions to reduce poverty need to be gender sensitive this research looked at whether the underground water irrigation technologies are accessible to both men and women. This paper is part of a hydraulic rights creation project in the broader Volta Basin. This study looked at how both men and women appropriate water resources for their benefit. This study concludes that shallow ground water technologies have to be grounded within the gendered production systems and tenurial arrangements which largely determine whether one benefits from water extraction technologies or not. In rural Africa where the majority of the poor households are de facto or de jure female headed, this paper proposes mechanisms for empowering women to benefit from ground water based irrigation.

This study combines climate change (CC), hydrological and water resource evaluation models to assess the impact of one downscaled mid-range CC scenario (A1B) on the performance of existing and planned irrigation and hydropower schemes in the Volta basin. The models were run (1983-2100) to simulate the CC scenario in combination with three development scenarios, each reflecting different levels of water resource development in the basin. Results indicate a general trend of declining rainfall and increasing potential evapotranspiration in the basin. This trend was found to have caused: i) a significant reduction in flows at key stream gauge locations; ii) an increase in average basin-wide per hectare irrigation requirement and iii) a significant reduction in the percentage of the potential hydropower that could be generated in the basin. This has the tendency to undermine the economic development of the riparian countries unless due consideration is given to these impacts and suitable adaptation measures introduced.
