Treadle pump (TP) technology has been promoted by Enterprise Works Worldwide (EWW) as an alternative to the traditional rope and bucket irrigation that is necessary to overcome the challenge of uncertain and inadequate rainfall for agricultural production. The aim is to improve output, increase incomes and reduce poverty among farm households. This study examines the strategies used for dissemination of the TP and the dynamics of its adoption and impacts, with a special focus on poverty reduction. The results of the study reveal that time and labor savings for irrigation, increased size of irrigated areas and lack of fuel requirements are the attractive features of the TP for those who adopt it. Adoption of TP increases land and labor productivities; and also net farm incomes. The study also demonstrates that adoption of the TP reduces poverty.

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.

In West Africa, especially in the Sahelian countries of Burkina Faso, Niger, Mali and Mauritania, erratic rainfall sequences within and between years has often led to a high uncertainty in rainfed crop production. Over the past three decades, severe food shortages attributed to drought have been frequently reported in several Sahelian countries, most of which are amongst the least developed of the world. Innovative and indigenous ways to achieve improved crop yields through integrated land and water management such as rainwater harvesting and soil water conservation have been successfully tested and, in some cases, adopted in West Africa. This paper highlights the successful interventions of improved indigenous rainwater harvesting/soil water conservation technologies such as Zaï or tassa, stone rows and half-moon in the Sahelian zones of West Africa over the past 10 years, and their contributions to enhancing food security and alleviating poverty. The potential for adoption of these technologies at the farm level and their outscaling to areas with similar agroecological zones are also discussed.

Irrigation is used for year-round cropping to sustain economic livelihoods in the Upper East region of Ghana, which experiences a long dry season and erratic rainfall during the rainy season. The sources of irrigation water are a few medium-size reservoirs (e.g. Tono and Vea) and a large number of small reservoirs scattered across the region. Other approaches include the application of shallow groundwater for vegetable cultivation. In recent times, pumping from rivers has increasingly been used to irrigate areas close to rivers to cultivate high value crops. Dry season irrigation cropping helps to increase household food security and also provides off-season employment for the many youths who are idle during this time of the year. This paper examines the different irrigation approaches in relation to the economic benefits to farmers, amidst growing concern for water availability for alternative uses. Net financial returns to land were similar for irrigation from small reservoirs and medium?sized reservoirs for vegetable production. Most of these smaller systems face problems, which include partial or complete drying-up of the reservoir in the dry season, high input costs (e.g. pumps and accessories), lack of access to credit facilities, and rapid deterioration and low profitability of medium scale schemes. The choice of irrigation water source such as dams (medium or small), or river pumping must be based on location specific criteria that maximise profitability, efficiency and sustainable use of the scheme.

In many parts of the world, improving rural livelihoods and income means transforming the way in which agricultural water is managed. Mali is a case in point. The Office du Niger formed in the 1930s as a centralized public enterprise to produce irrigated cotton and rice, has been significantly revamped since the 1990s. The result has been dramatic gains in rice production and farm incomes, and reductions in rural poverty. The case shows that changing agricultural water management requires a supportive macro-policy environment, and appropriate institutional changes and infrastructural investments. Equally important, it shows that those reforms may need to precede improvements in water management. Moreover, in aid-dependent low income countries reform cannot occur unless both government and donors concur on the need for change. Finally, the case drives home that improving water management is a continuing process; gains to date in economic efficiency and (to a lesser extent) equity in the Office du Niger now need to be matched by improvements in environmental sustainability.

The major goal of this research was to delineate the shallow groundwater irrigated areas (SGI) in the Atankwidi Watershed in the Volta River Basin of West Africa. Shallow ground water irrigation is carried out using very small dug-wells all along the river banks or shallow dug-outs all along the river bed. Each of these dug-wells and dug-outs are highly fragmented small water bodies that irrigate only a fraction of an acre. However, these are contiguous dug-wells and dug-outs that are hundreds or thousands in number. Very high spatial resolution (VHSR) Quickbird imagery (0.61 to 2.44 m) was used to identify: (a) dug-wells that hold small quantities of water in otherwise dry stream; and (b) dug-outs that are just a meter or two in depth but have dug-out soils that are dumped just next to each well. The Quickbird VHSR imagery was found ideal to detect numerous: (i) dug-wells through bright soils that lay next to each dug-well, and (ii) water bodies all along the dry stream bed. We used fusion of 0.61 m Quickbird panchromatic data with 2.44 Quickbird multispectral data to highlight SGI and delineate their boundaries. Once this was achieved, classification techniques using Quickbird imagery was used within the delineated areas to map SGI and other land use/land cover (LULC) areas. Results obtained showed that SGI is practiced on a land area of 387 ha (1.4%), rainfed areas is 15638 ha (54.7%) and the remaining area in other LULC. These results were verified using field-plot data which showed an accuracy of 92% with errors of omissions and commissions less than 10%.

Mangroves areas in Casamance have been traditionally used for rice growing, fishing, fish culture, shell picking and wood. Senegal has been affected by drought since 1963 and this has had an adverse effect on the mangroves leading to a decrease in the total area. Intensification of agriculture and increasing population pressure has resulted in increased erosion and siltation. Given the shortage of rainfall due to recurrent droughts over the last three decades, one can easily observe a tendency towards increased salinity of soils and the underlying water table. Site development has become the only solution to the salt intrusion problem since early 1970s.The present paper focuses on the different types of site development such as the traditional polder and anti-small dams and their role in increasing rice production.

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.

Treadle pump (TP) technology has been promoted by Enterprise Works in West Africa as an alternative to the traditional rope and bucket irrigation. The aim is to improve output and incomes and reduce poverty among farm households. This paper reports a short term (two years) assessment of the dynamics of its adoption and impacts, with a special focus on poverty reduction. Data used were from primary surveys of adopters and non-adopters of treadle pumps in two regions of Ghana. The data were analyzed using descriptive statistics, budgetary and production function analysis. The results of the study reveal that time and labor savings for irrigation were the major attractive features of the treadle pump for those who adopted it. The difference in net income between adopters and non-adopters was about US$393 per hectare, with an increase in land and labor productivities. About 21% stopped the use of the treadle pump because it broke down, while about 10% shifted to motorized pumping. The study shows that adoption of treadle pumps reduces poverty. It is recommended that increased collaboration with local institutions, such as extension services, will improve the transfer of treadle pump technology to farmers. After-sales service and training of farmers on repairs could reduce treadle pump abandonment. This paper is original as it compares the factors that affect adoption and non-adoption of treadle pumps. It also reveals reasons for abandonment. A multivariate analysis was used to examine the productivity impact of adoption.

The Atankwidi Catchment, which lies in the White Volta Basin in West Africa, is intensively cultivated by locals for economic gains. During dry seasons, farmers irrigate their crops, chiefly tomatoes, using shallow groundwater harvested from shallow ponds they dig using simple tools like an axe, hoe, bucket and bowls. Recent expansion in cultivated areas has brought to the fore the need to estimate the volume of shallow groundwater stored in the catchment’s underlying aquifer and to what extent it can sustain the incremental growth in irrigated areas.

Irrigation in Sahelian West African countries covers a wide variety of systems and practices. In this paper, we discuss various technical and managerial options including free or controlled submersion, improved inland valleys, ood recession cropping, and full control in small and large irrigation schemes through a classi cation developed by national experts in ve Sahelian countries. Governments are currently promoting two strategies. One is based on large schemes, with foreign or national private investment. The other is based on small private irrigation approches. Water constraints are notvery strongly taken into account, as the priority is to develop new schemes in order to reach food security for fast growing cities.
