Smallholder Irrigation Technology
Author: Melvyn Kay
Publisher: Food & Agriculture Org.
ISBN: 9789251045947
Category : Technology & Engineering
Languages : en
Pages : 52
Book Description
This report is a view of irrigation technologies for smallholders in the context of improving rural livelihoods, especially in regard to the prospects for sub-Saharan Africa. The role of traditional technologies is evaluated and modern water distribution technologies, such as sprinkler and trickle irrigation, are reviewed. A broad classification has been made based on climate and the traditional agricultural background of the local people, which links technology options to specific places--to agricultural regions and to countries.

Private irrigation in Sub-Saharan Africa: regional Seminar on Private Sector Participation and Irrigation Expansion in Sub-Saharan Africa, Accra, Ghana, 22-26 October 2001
Author: Hilmy Sally
Publisher: IWMI
ISBN: 9290904941
Category : Agricultural development projects
Languages : en
Pages : 384
Book Description
Only 4 percent of arable land in sub-Saharan Africa is irrigated, using just 2 percent of the available water resources. Furthermore, 18 percent of the area equipped for irrigation is not utilized at all and the intensity of use varies between 50 percent and 80 percent. This highlights the huge potential available for intensifying and expanding irrigated area, provided that the investments required can be successfully mobilized. However, it must be noted that if investments in irrigation are to yield satisfactory returns, investments must also be made in a series of related activities. Current global figures for the amount of private investment in irrigation confirm that good returns can indeed be achieved. Prospects for sub-Saharan Africa would be far more favorable if public development assistance, particularly foreign direct investments, did not show declining trends.

The Impact of Irrigation on Nutrition, Health, and Gender

ISBN:
Category : Social Science
Languages : en
Pages : 28
Book Description
Agriculture in Africa south of the Sahara (SSA) is still largely rainfed. SSA also exhibits the lowest crop yields for major staples in the world, largely due to low use of irrigation and fertilizer. Rainfed agriculture poses growing production risks with increased climate variability and change. At the same time, smallholder irrigation in the region developed rapidly over the past decade, albeit starting from very low levels. In addition to largely demand-driven irrigation development by smallholders, there is a significant push by donors for large-scale irrigation development, as well as some push for smallholder irrigation. There has also been a long-standing debate about whether irrigation in SSA should be large scale or small scale to achieve its potential. However, given the potentially high rewards, but also high possibility of failure, the assessment of irrigation potential must go beyond large scale versus small scale to integrate concerns regarding environmental sustainability, resource use efficiency, nutrition and health impacts, and womens empowerment. The hypothesis underlying this review paper is that how irrigation gets deployed in SSA will be decisive not only for environmental sustainability (such as deciding remaining forest cover in the region) and poverty reduction, but also for health, nutrition, and gender outcomes in the region. The focus of this paper is on the health, nutrition, and gender linkage. We find that to date, few studies have analyzed the impact of irrigation interventions on nutrition, health, and womens empowerment, despite the large potential of irrigation to affect these important variables. Irrigation interventions may have differential effects on different members in the household and in the community, such as irrigators, non-irrigators, children, and women. Measuring and understanding such differences, followed by improving design and implementation to maximize gender, health, and nutrition outcomes, could transform irrigation programs from focusing solely on increased food production toward becoming an integral component of poverty-reduction strategies.

Costs and Performance of Irrigation Projects
Author: Arlene B. Inocencio
Publisher: IWMI
ISBN: 9290906588
Category : Irrigation projects
Languages : en
Pages : 86
Book Description
High irrigation investment costs together with declining world prices for food and the failures of a number of high profile past irrigation projects are the main reasons for the reluctance of development agencies and governments in sub-Saharan Africa to invest more resources in irrigation. This study aims to systematically establish whether costs of irrigation projects in sub-Saharan Africa are truly high, determine the factors which influence costs and performance of irrigation projects, and recommend cost-reducing and performance-enhancing options to make irrigation investments in the region more attractive. It analyzes 314 irrigation projects implemented from 1967 to 2003 in 50 countries in Africa, Asia, and Latin America funded by the World Bank, African Development Bank and the International Fund for Agricultural Development.
