Typology of irrigation systems in Ghana by Namara, Regassa E.,Horowitz, L.,Kolavalli, S.,Kranjac-Berisavljevic, G.,Dawuni, B. N.,Barry, Boubacar,Giordano, Mark Pdf
Interest in African irrigation investment is growing. However, irrigation is not a monolithic concept, and the opportunities and risks can vary substantially by approach. To help provide an understanding of the variation, this paper builds on previous work to provide a detailed typology of irrigation systems as currently used in Ghana.
Generic Typology for Irrigation Systems Operation by Daniel Renault,Godaliyadde Gedara Ariyarathne Godaliyadda Pdf
This report presents a methodology for identifying the main features (constraints and opportunities) of gravity-fed irrigation systems, which influence management and operation of the system for the purpose of water delivery. It presents the development of a generic for improving irrigation system operations. A case study of 64 irrigation systems in Sri Lanka is presented illustrating the practical application of the proposed typology.

Investing in agricultural water management to benefit smallholder farmers in Ghana. AgWater Solutions Project country synthesis report by Evans, Alexandra E. V.,Giordano, Meredith,Clayton, Terry (Eds.) Pdf
The AgWater Solutions Project, carried out between 2009 and 2012, focused on resolving water issues faced by smallholder farmers. The project examined existing Agricultural Water Management (AWM) solutions, together with factors that influence their adoption and scaling up. The project aimed to identify investment opportunities in AWM that have high potential to improve the incomes and food security of poor farmers. The work was undertaken in the African countries of Burkina Faso, Ethiopia, Ghana, Tanzania and Zambia, and in the Indian States of Madhya Pradesh and West Bengal. This Working Paper series summarizes results and recommendations from the research carried out in each of these countries and states.
Irrigation-nutrition linkages: Evidence from northern Ghana by Mekonnen, Dawit Kelemework,Choufani, Jowel,Bryan, Elizabeth,Abizari, Abdul-Razak,Ringler, Claudia,Amikuzuno, Joseph Pdf
We analyze the linkages between irrigation and nutrition using data from irrigators and non-irrigators in Northern Ghana. The results show that (i) there is a modest difference in the overall household dietary diversity score between irrigators and non-irrigators, (ii) there are significant differences in the consumption of animal source foods between irrigators and non-irrigators, (iii) there are significant differences in the consumption of fruits and vegetables as well as sugar and honey between irrigators and non-irrigators, and (iv) the sources of food consumption differ between irrigators and non-irrigators. The analysis shows strong association between households’ nutritional status and their access to irrigation, with evidences suggesting that the irrigation-nutrition linkages play out both through the income and production pathways in Northern Ghana.
Agro-climatic and hydrological characterization of selected watersheds in northern Ghana by Kadyampakeni, Davie M.,Mul, Marloes L.,Obuobie, E.,Appoh, Richard,Owusu, Afua,Ghansah, Benjamin,Boakye-Acheampong, Enoch,Barron, Jennie Pdf
Sustainable Irrigation Development in the White Volta sub-Basin by Eric Antwi Ofosu Pdf
Sub-Saharan Africa has an irrigation potential of about 42 million hectares of which only 17% is developed. Despite several investments in irrigation the growth is slow. This study aims at helping to achieve sustainable irrigation in sub-Saharan Africa, through gaining a better understanding of productive irrigation water use and effective manageme
The Water Resource Implications of Changing Climate in the Volta River Basin by Matthew McCartney,Gerald Forkuor,Aditya Sood,Barnabas Amisigo,Fred Hattermann,Lal Muthuwatta Pdf
The Volta River is one of the major rivers in Africa. In this study, a dynamic regional climate model (CCLM), a hydrological model (SWAT) and a water resource model (WEAP) were used to provide an assessment of one downscaled ‘middle impact’ climate change scenario on the performance of existing and planned irrigation and hydropower schemes. The results indicate that, by the middle of the twenty-first century, altered climate is likely to undermine the technical performance of existing and planned reservoirs, which will, in turn, affect development outcomes. Future water resources development in the basin requires interventions that bolster resilience and water security. Much more systematic planning of water storage, greater cooperation between the riparian states and consideration of innovative approaches to water storage are needed.
Groundwater - New Advances and Challenges by Jamila Tarhouni Pdf
Groundwater is the largest natural resource in the world. The estimation of groundwater resources as well as their sustainable management are challenges for users, practitioners, managers, and decision-makers. These challenges can be solved based on the progress in three domains: (1) data modeling (2) data science, and (3) advanced systems of ground measurement and Earth data. This book contributes to the progress of groundwater characterization by addressing some challenges through applications and discussions of relevant case studies as well as new approaches. It contains six chapters that discuss various approaches and tools used to study and investigate the impacts of climate change and pollution risks. They also present techniques for accessing water that may contribute to sustainable exploitation and management of groundwater resources.
Flood recession agriculture for food security in Northern Ghana by Sidibe, Yoro,Williams, Timothy O.,Kolavalli, Shashidhara Pdf
This review describes a range of physical and socio-economic scientific methods and field activities that will be implemented in a proposed research project to develop a better understanding of the extent and patterns of flooding and the potential of flood-recession agriculture. These activities will allow the hydrological characteristics of the river to be matched to crop-livestock systems of flood recession agriculture that are well suited to the study communities and their organizational and institutional frameworks in order to support sustainable growth of such systems. This detailed study will provide recommendations on the technical, economic, institutional and policy measures needed to achieve sustainable intensification of flood recession agriculture in northern Ghana, while complementing efforts undertaken to promote other types of water management systems. Options for out-scaling of flood recession agriculture beyond the study area to other suitable areas will also be explored. The expectation is that the proposed project will improve food security by enhancing knowledge on effective flood recession practices, enhance rural incomes through expanded dry-season farming with new opportunities for rural employment, and improve adaptation to climate change by building more resilient farming communities. To achieve these expected outcomes, proactive policies that clearly identify flood recession agriculture as an alternative farming practice and provide institutional mandates to irrigation support services to promote it through training, demonstration, and outreach programs will be equally valuable.
Smallholder Irrigation Technology by Melvyn Kay Pdf
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.
Women and small-scale irrigation: A review of the factors influencing gendered patterns of participation and benefits by Bryan, Elizabeth,Lefore, Nicole Pdf
Small-scale irrigation is expanding rapidly in parts of the world, especially sub-Saharan Africa, offering smallholder farmers an opportunity to improve their livelihoods, diets, and resilience to climate change among other benefits. Growing research focuses on the potential for small-scale irrigation to offer a pathway for women’s empowerment, yet the factors conditioning the relationship between small-scale irrigation and women’s empowerment are not well understood. The evidence tends to be scattered across context-specific case studies that focus on targeted outcomes, without distinguishing between technology types, scales, or approaches to irrigation systems or technologies. This paper synthesizes the issues related to gender and small-scale irrigation using a conceptual framework that highlights the linkages between elements of women’s empowerment and small-scale irrigation. Because gendered dynamics with small-scale irrigation play out differently depending on the scale of irrigation and the technologies used, this paper applies the framework to examine case studies across a typology of small-scale irrigation systems. The case studies cover a range of farming and livelihood systems in which women’s roles and gender relations vary, highlighting the importance of the opportunity structure or context in which irrigation takes place. This paper then draws lessons on the various ways in which small-scale irrigation, gender relations, and women’s empowerment interact and highlights areas where research gaps remain.
