Book Synopsis Smallholder irrigation technology diffusion in Ghana: Insights from stakeholder mapping by : Atuobi-Yeboah, Afua

This book was released on 2020-11-12 with total page 40 pages. Available in PDF, EPUB and Kindle. Book excerpt: Irrigated agriculture can support food and nutrition security, increase rural employment and incomes and can act as a buffer against growing climate variability and change. However, irrigation development has been slow in Africa south of the Sahara and Ghana is no exception. Out of a total potential irrigated area of close to 2 million ha, less than 20,000 ha large-scale irrigation and less than 200,000 ha of small-scale irrigation have been developed; but the latter is only an estimate. To identify entry points for accelerating small-scale irrigation development in Ghana, a national and a regional stakeholder Net-Map workshop were held in Accra and Tamale, respectively. The workshops suggest that a wide variety of actors from government, the private sector, international organizations and funders, research organizations and NGOs are involved in the diffusion of small-scale irrigation technologies. However, there are important differences between actors perceived to be key at the national and at the regional levels in northern Ghana. At the national level, diffusion of small-scale irrigation technologies is considered to be largely influenced by the Ghana Irrigation Development Authority together with a series of private sector actors focused on importation, distribution and financing of technologies. Farmers are considered to have no influence over the diffusion of small-scale irrigation, suggesting that small-scale irrigation is largely considered a supply-driven process. In northern Ghana, on the other hand, farmers are considered to be key influencers, although participants noted that much of this was potential influence, together with a larger and more diversified set of government stakeholders that are seen as regulators and possibly gatekeepers. For irrigation diffusion to successfully move from importation to distribution to benefiting smallholder farmers, all of these actors have to come together to better understand farmers’ needs and challenges. A multi-stakeholder platform could help to increase communication between farmers as the ultimate beneficiaries of small-scale irrigation technologies and the many other actors interested in supporting this process.
Book Synopsis Fundamentals of Smallholder Irrigation by : B. Albinson
Download or read book Fundamentals of Smallholder Irrigation written by B. Albinson and published by IWMI. This book was released on 2002 with total page 30 pages. Available in PDF, EPUB and Kindle. Book excerpt: Smallholder irrigation systems–where farm sizes generally range from a fraction of a hectare to 10 hectares–pose special management problems, especially where the water available for irrigation is frequently less than the demand. The intensity of system adjustments required to meet individual farmer demands, and the administrative complexity of measuring and accounting water deliveries have generally proven excessive when attempting to meet “on demand†schedules, resulting in chaos (often characterized by illegal tampering with infrastructure, and vast differences of water use intensity at different locations in the system). The alternative–provision of a simple service, based on proportional sharing of available supplies on the basis of landholdings–has been resilient for many years over vast areas. The approach is based on a clear delineation between the part of the irrigation system that is actively managed (at various flow rates and water levels) and the part of the system that operates either at full supply level (with proportional division of water down to the level at which farmers rotate among their individual farms), or is completely shut. This operational design is known as a “structured†system, and has well-defined hydraulic characteristics, simplifying operation and management, in turn allowing a clearer definition of water entitlements and the responsibilities of agency staff and farmers. The approach is particularly suited to areas where water is scarce and discipline is needed to ration water among users. An additional benefit, which has been demonstrated in modeling studies using a well–proven model relating to water and yield, is that the productivity of water (which is more important than the more traditional productivity of land when water is scarce) is substantially increased when deficit irrigation is practiced–a widely observed and predictable response to rationed water supplies. Structured systems are most suited where water is scarce, clear definition of water entitlements is needed, management capacity is limited, and investment resources are limited. The approach to determining critical aspects of a structured system design is described in this report.
Book Synopsis Smallholder irrigation technology diffusion in Mali: Insights from stakeholder mapping by : Houeto, Dede Aduayom

This book was released on 2022-06-16 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Small-scale irrigation has significant potential to increase crop productivity in Mali, in particular given growing climate change impacts on the country and region. While large-scale development is substantial, small, private irrigation remains limited, affecting food and particularly nutrition security as small-scale technologies are more likely to be used for high-value vegetable crops. To better understand the challenges and opportunities in the diffusion of small-scale irrigation technologies, two workshops were organized in 2021 at the national and regional levels, respectively, to consider national and local factors supporting the diffusion of small-scale irrigation technologies. Key constraints identified were a lack of linkages between intermediary organizations in the small-scale irrigation diffusion process, such as commodity associations, financial institutions and technology vendors with government agencies in charge of irrigation, limiting the sharing of consistent and effective information across entities; the lack of a clear policy framework and long-term guidance for private individual irrigation; an associated lack of targeted technology development including limited adaptation to different local contexts, missing financial products linked to irrigation technology, and inadequate capacity building of farmers through extension services and demonstration sites. Workshop participants suggested a dedicated platform for more effective information exchange across the key actors identified in the events, improved capacity building on private irrigation, and a supportive policy and financial environment to ensure growth and sustainability of small-scale irrigation development in the country.

Book Synopsis The diffusion of small-scale irrigation technologies in Ethiopia: Stakeholder analysis using Net-Map by : Bryan, Elizabeth
Download or read book The diffusion of small-scale irrigation technologies in Ethiopia: Stakeholder analysis using Net-Map written by Bryan, Elizabeth and published by Intl Food Policy Res Inst. This book was released on 2020-07-21 with total page 42 pages. Available in PDF, EPUB and Kindle. Book excerpt: Small-scale irrigation (SSI) provides great benefits to farmers in terms of increased yields and profits, better food and nutrition security and greater resilience to climate shocks. Ethiopia has high potential for expanding SSI and has invested considerably in this area in recent years. Despite these investments, several challenges to further expansion of irrigation technologies remain. Different stakeholders in the country play important roles in overcoming these barriers to further scale technologies for SSI. This paper explores institutional arrangements for the diffusion of small-scale irrigation technologies by mapping the landscape of key actors involved, their interconnections, and their influence. This paper draws on an analysis of stakeholder data collected through two participatory workshops in Ethiopia, one at the national level and one at the Oromia regional level, using the Net-Map approach. Results show the dominance of government actors in the diffusion of SSI at both the national and regional levels, while most private sector and NGO actors remain in the periphery. Participants in both workshops highlighted the need for increased financing services to support the adoption of SSI and measures aimed at increasing the supply of high-quality irrigation equipment, such as modern water lifting technologies. One notable difference between the national and regional results was that at the regional level, farmers, and to some extent traders and input suppliers, were considered to be more influential in the diffusion of irrigation technologies, while they were considered marginal actors at the national level.

Book Synopsis Women and small-scale irrigation: A review of the factors influencing gendered patterns of participation and benefits by : Bryan, Elizabeth
Download or read book Women and small-scale irrigation: A review of the factors influencing gendered patterns of participation and benefits written by Bryan, Elizabeth and published by Intl Food Policy Res Inst. This book was released on with total page 48 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Book Synopsis Drip Irrigation for Agriculture by : Jean-Philippe Venot
Download or read book Drip Irrigation for Agriculture written by Jean-Philippe Venot and published by Routledge. This book was released on 2017-07-06 with total page 362 pages. Available in PDF, EPUB and Kindle. Book excerpt: Initially associated with hi-tech irrigated agriculture, drip irrigation is now being used by a much wider range of farmers in emerging and developing countries. This book documents the enthusiasm, spread and use of drip irrigation systems by smallholders but also some disappointments and disillusion faced in the global South. It explores and explains under which conditions it works, for whom and with what effects. The book deals with drip irrigation 'behind the scenes', showcasing what largely remain 'untold stories'. Most research on drip irrigation use plot-level studies to demonstrate the technology’s ability to save water or improve efficiencies and use a narrow and rather prescriptive engineering or economic language. They tend to be grounded in a firm belief in the technology and focus on the identification of ways to improve or better realize its potential. The technology also figures prominently in poverty alleviation or agricultural modernization narratives, figuring as a tool to help smallholders become more innovative, entrepreneurial and business minded. Instead of focusing on its potential, this book looks at drip irrigation-in-use, making sense of what it does from the perspectives of the farmers who use it, and of the development workers and agencies, policymakers, private companies, local craftsmen, engineers, extension agents or researchers who engage with it for a diversity of reasons and to realize a multiplicity of objectives. While anchored in a sound engineering understanding of the design and operating principles of the technology, the book extends the analysis beyond engineering and hydraulics to understand drip irrigation as a sociotechnical phenomenon that not only changes the way water is supplied to crops but also transforms agricultural farming systems and even how society is organized. The book provides field evidence from a diversity of interdisciplinary case studies in sub-Saharan Africa, the Mediterranean, Latin America, and South Asia, thus revealing some of the untold stories of drip irrigation.

This book was released on 2022-07-02 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Irrigation is increasingly promoted in Africa south of the Sahara, but the benefit streams of small-scale irrigation in Mali remain largely unknown. This study collected detailed quantitative data of irrigators and non-irrigators in two regions of Mali: Mopti, which is in the Sahelian zone, and Sikasso, the southernmost region of the country, which receives more rainfall. Econometric results show that the irrigation suitability, female household headship, proximity to markets and market participation increase the propensity to irrigate. The results suggest that small-scale irrigation investments have the potential to benefit women farmers directly. We used Two-Stage Weighted treatment effects multivariate regression to identify the impact of irrigation on selected outcomes. The impact assessment results show that crop income and diversification, market participation, employment, and dietary quality were substantially higher in irrigated farms compared to non-irrigated farms. Likewise, irrigating households had higher food security and higher dietary diversity. The results show that irrigation is a key entry point for combatting climate variability and change. However, the low adoption levels of improved water-lifting technologies are a major challenge. Limited promotion of solar and motorized pumps has contributed to the low adoption of these improved water-lifting technologies. A less profitable option, lifting water with a rope-and-bucket system, remains the most common water-lifting technology in the study areas. We find that investing in effective advisory services that target agricultural water management could increase uptake of more profitable irrigation technologies.
Book Synopsis Gender Aspects of Small-scale Private Irrigation in Africa by : Barbara van Koppen
Download or read book Gender Aspects of Small-scale Private Irrigation in Africa written by Barbara van Koppen and published by IWMI. This book was released on 2013-03-06 with total page 28 pages. Available in PDF, EPUB and Kindle. Book excerpt: This Working Paper presents methodological and substantive findings of gender-differentiated quantitative farm household surveys about smallholder’s private irrigation technology adoption in Ghana and Zambia. Focusing on three gender variables, household headship, labor provision and plot management, the paper examines adoption rates, types of technologies and gendered labor provision in female- and male-headed households; compares adoption rates on women’s own plots with overall rates; compares women’s decision-making on irrigated plots and rainfed plots; and examines impacts of targeting strategies. Findings suggest that women are proactive irrigation adopters in spite of the many obstacles they face. Removing those obstacles serves both gender equality and irrigation policies.
