Download or read book Rainwater harvesting technologies in the Sahelian zone of West Africa and the potential for outscaling written by Barry, Boubacar and published by IWMI. This book was released on 2009-05-11 with total page 44 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Water Harvesting in Sub Saharan Africa written by William Critchley and published by Routledge. This book was released on 2013-01-04 with total page 219 pages. Available in PDF, EPUB and Kindle. Book excerpt: Agriculture in Sub-Saharan Africa is constrained by highly variable rainfall, frequent drought and low water productivity. There is an urgent need, heightened by climate change, for appropriate technologies to address this problem through managing and increasing the quantity of water on farmers’ fields – water harvesting. This book defines water harvesting as a set of approaches which occupy an intermediate position along the water-management spectrum extending from in situ moisture conservation to irrigated agriculture. They generally comprise small-scale systems that induce, collect, store and make use of local surface runoff for agriculture. The authors review development experience and set out the state of the art of water harvesting for crop production and other benefits in Sub-Saharan Africa. This includes an assessment of water harvesting schemes that were initiated two or three decades ago when interest was stimulated by the droughts of the 1970s and 1980s. These provide lessons to promote sustainable development of dryland agriculture in the face of changing environmental conditions. Case studies from eight countries across Sub-Saharan Africa provide the evidence base. Each follows a similar format and is based on assessments conducted in collaboration with in-country partners, with a focus on attempts to promote adoption of water harvesting, both horizontally (spread) and vertically (institutionalization). Introductory cross-cutting chapters as well as an analytical conclusion are also included.

Available in PDF, EPUB and Kindle. Book excerpt: This book introduces state-of-the-art approaches, methods and research, focusing on smart management of rainwater. In addition, it provides an overview of projects from across the world, illustrating how rainwater-smart management has been implemented in drylands. Focusing on the scientific perspective it demonstrates how rural dryland agriculture can be improved. It also documents the wealth of rainwater-smart know-how available today, and replicates and transfers results to other countries and regions, to encourage cross-sector interactions among various stakeholders, such as practitioners from governmental and public organisations, policy- and decision-makers, and teaching staff from academic scientific institutions. The contributors showcase vital lessons learned from research, field projects and best-practice examples. They address the integrated use of rainwater harvesting management with landscape restoration practices and water-, and climate-smart agriculture for food security and poverty alleviation in arid and semi-arid areas. Original research, combined with the contributors’ synthetic approach, lays a foundation for new concepts and ideas. Through case studies and research reports, the book discusses all the relevant issues necessary for the comprehensive analysis and successful implementation of the technologies in rainwater management. Highlighting the working principles and technical recommendations with regard to cost-efficient rainwater-smart solutions, it is of interest to practitioners. It is also a valuable resource for academic specialists, professionals and students, since many development agencies are funding rainwater harvesting for irrigation purposes.

This book was released on 2015-04-23 with total page 184 pages. Available in PDF, EPUB and Kindle. Book excerpt: Africa is endowed with rich land and water resources, which significantly contribute to the development of many economies on the continent. However, land degradation and water pollution remain major challenges facing many African countries. Harnessing Land and Water Resources for Improved Food Security and Ecosystem Services in Africa examines challenges facing land and water resources management in Africa and explores possible measures to improve food security and reduce poverty on the continent. The book is a compilation of research papers, written by eminent researchers and scientists from renowned Universities and reputable organisations in Ghana, Ethiopia, USA, South Africa, Nigeria, the Netherlands and Indonesia. Its main objective is to draw attention to the impact of human activities on land and water resources and the need for the sustainable management of Africa's ecosystem services to improve livelihoods. The individual chapters present relevant case studies on the effects of water and land management practices including urban waste water uses, land grabbing and climate change issues, so as to draw lessons from best practices that can be adopted to mitigate their efforts on food security and the well-being of the African population. The monograph concludes with recommendations on the appropriate strategies for managing wastelands to meet Africa's green energy needs.

This book was released on 2023-03-29 with total page 300 pages. Available in PDF, EPUB and Kindle. Book excerpt: Agriculture is vitally important to humanity. Climate change, environmental pollution, global warming, and the COVID-19 pandemic have highlighted the importance of food safety and food security. This book discusses sustainable agriculture and its importance in combatting the adverse effects of climate change and meeting the world’s food demand. And essentially the technologies to be used for CE to prevent climate change should be “common property of humanity”. This may be a new paradigm, but the real issue is the future of the earth and ensuring the continuity of sustainable life. It is a fact that the creation of such a culture of sharing will serve all the SDGs put forward by the UN.

Download or read book Indigenous Water and Drought Management in a Changing World written by Miguel Sioui and published by Elsevier. This book was released on 2022-05-19 with total page 354 pages. Available in PDF, EPUB and Kindle. Book excerpt: Indigenous Water and Drought Management in a Changing World presents a series of global case studies that examine how different Indigenous groups are dealing with various water management challenges and finding creative and culturally specific ways of developing solutions to these challenges. With contributions from Indigenous and non-Indigenous academics, scientists, and water management experts, this volume provides an overview of key water management challenges specific to Indigenous peoples, proposes possible policy solutions both at the international and national levels, and outlines culturally relevant tools for assessing vulnerability and building capacity. In recent decades, global climate change (particularly drought) has brought about additional water management challenges, especially in drought-prone regions where increasing average temperatures and diminishing precipitation are leading to water crises. Because their livelihoods are often dependent on the land and water, Indigenous groups native to those regions have direct insights into the localized impacts of global environmental change, and are increasingly developing their own adaptation and mitigation strategies and solutions based on local Indigenous knowledge (IK). Many Indigenous groups around the globe are also faced with mounting pressure from extractive industries like mining and forestry, which further threaten their water resources. The various cases presented in Indigenous Water and Drought Management in a Changing World provide much-needed insights into the particular issues faced by Indigenous peoples in preserving their water resources, as well as actionable information that can inform future scientific research and policymaking aimed at developing more integrated, region-specific, and culturally relevant solutions to these critical challenges. - Includes diverse case studies from around the world - Provides cutting-edge perspectives about Indigenous peoples' water management issues and IK-based solutions - Presents maps for most case studies along with a summary box to conclude each chapter

Download or read book Contested Agronomy written by James Sumberg and published by Routledge. This book was released on 2012-03-15 with total page 278 pages. Available in PDF, EPUB and Kindle. Book excerpt: The dramatic increases in food prices experienced over the last four years, and their effects of hunger and food insecurity, as well as human-induced climate change and its implications for agriculture, food production and food security, are key topics within the field of agronomy and agricultural research. Contested Agronomy addresses these issues by exploring key developments since the mid-1970s, focusing in particular on the emergence of the neoliberal project and the rise of the participation and environmental agendas, taking into consideration how these have had profound impacts on the practice of agronomic research in the developing world especially over the last four decades. This book explores, through a series of case studies, the basis for a much needed ‘political agronomy’ analysis that highlights the impacts of problem framing and narratives, historical disjunctures, epistemic communities and the increasing pressure to demonstrate ‘success’ on both agricultural research and the farmers, processors and consumers it is meant to serve. Whilst being a fascinating and thought-provoking read for professionals in the Agriculture and Environmental sciences, it will also appeal to students and researchers in agricultural policy, development studies, geography, public administration, rural sociology, and science and technology studies.
Download or read book Assessing the economic impact of redistributing water within a catchment a case study of the Musi Catchment in the Krishna Basin in India written by Brian Davidson and published by IWMI. This book was released on 2010-05-13 with total page 50 pages. Available in PDF, EPUB and Kindle. Book excerpt: The aim in this paper was to present the details of an economic modeling exercise conducted on the Musi Catchment of the Krishna Basin. The model has the unique characteristic of being able to value the water used on individual crops and in different regions. Thus, the individual values of water used to produce different crops, grown over two different seasons and over five very different regions within a catchment, were determined. This is a significant improvement over previous attempts, where a single value of water in a catchment was derived regardless of what it is used for, when it was used and where it used in the catchment. In addition to the agricultural valuation process, some account was made for the other uses of water and how they should be valued. The worth of these findings cannot be underestimated as the results are useful to those who need to allocate scarce water supplies between competing uses within a catchment. The assumptions underlying the model, the data used and the results and implications drawn are fully detailed in this paper. This model was connected to a hydrological model and used to simulate various scenarios on the water situation facing users in the basin. This model is the forerunner of similar modeling attempts on similar problems in other regions of the Krishna Basin and in the Murray Darling Basin of Australia.
