Download or read book 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 written by Hilmy Sally and published by IWMI. This book was released on 2011-10-21 with total page 384 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: "In order to face the challenge of disappointing returns on public investment in irrigation and drainage new solutions have emerged. These solutions are based on widely available technology and new management and governance options. The main message of Re-engaging in Agricultural Water Management is that the irrigation and drainage sector should not continue to be dealt with as a standalone sector, but should be integrated into a broader perspective, one that embraces the objectives of productivity growth, poverty reduction, natural resources management and environmental protection."

Download or read book Improved Agricultural Water Management for Africa s Drylands written by Christopher Ward and published by World Bank Publications. This book was released on 2016-08-23 with total page 177 pages. Available in PDF, EPUB and Kindle. Book excerpt: D ryland regions in Sub-Saharan Africa are home to one-half of the region’s population and three-quarters of its poor. Poor both in natural resources and in assets and income, the inhabitants of drylands are highly vulnerable to droughts and other shocks. Despite a long history of interventions by governments, development agencies, and civil society organizations, there have been no sustained large-scale successes toward improving the resilience of drylands dwellers. Improved Agricultural Water Management for Africa’s Drylands describes the extent to which agricultural water management interventions in dryland regions of Sub-Saharan Africa can enhance the resilience and improve the well-being of the people living in those regions, proposes what can realistically be done to promote improved agricultural water management, and sets out how stakeholders can make those improvements. After reviewing the current status of irrigation and agricultural water management in the drylands, the authors discuss technical, economic, and institutional challenges to expanding irrigation. A model developed at the International Food Policy Research Institute is used to project the potential for irrigation development in the Sahel Region and the Horn of Africa. The modeling results show that irrigation development in the drylands can reduce vulnerability and improve the resilience of hundreds of thousands of farming households, but rainfed agriculture will continue to dominate for the foreseeable future. Fortunately, many soil and water conservation practices that can improve the productivity and ensure the sustainability of rainfed cropping systems are available. The purpose of this book is to demonstrate the potentially highly benefi cial role of water and water management in drylands agriculture in association with agronomic improvements, market growth, and infrastructure development, and to assess the technological and socioeconomic conditions and institutional policy frameworks that can remove barriers to adoption and allow wide-scale take-up of improved agricultural water management in the dryland regions of Sub-Saharan Africa.

This book was released on 2009 with total page 300 pages. Available in PDF, EPUB and Kindle. Book excerpt: "The food problems now facing the world-scarcity and starvation, contamination and illness, overabundance and obesity-are both diverse and complex. What are their causes? How severe are they? Why do they persist? What are the solutions? The authors of the more than sixty international case studies contained in these books approach the food system with a multidisciplinary perspective. In three volumes that serve as valuable teaching tools, they call upon the wisdom of disciplines including economics, nutrition, sociology, anthropology, environmental science, medicine, and geography to create a holistic picture of the state of the world's food systems today. The authors focus in on specific cases from all corners of the globe to cover topics including drought and soil conservation; land allocation and cooperative marketing efforts; and food safety measures and advertising policies. In documenting past successes and failures, these case studies provide a valuable foundation for future research and efforts to create truly successful and sustainable food policy."--Pub. desc.

Download or read book Introduction to the Numerical Modeling of Groundwater and Geothermal Systems written by Jochen Bundschuh and published by CRC Press. This book was released on 2010-07-05 with total page 1373 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides an introduction to the scientific fundamentals of groundwater and geothermal systems. In a simple and didactic manner the different water and energy problems existing in deformable porous rocks are explained as well as the corresponding theories and the mathematical and numerical tools that lead to modeling and solving them. This approach provides the reader with a thorough understanding of the basic physical laws of thermoporoelastic rocks, the partial differential equations representing these laws and the principal numerical methods, which allow finding approximate solutions of the corresponding mathematical models. The book also presents the form in which specific useful models can be generated and solved. The text is introductory in the sense that it explains basic themes of the systems mentioned in three areas: engineering, physics and mathematics. All the laws and equations introduced in this book are formulated carefully based on fundamental physical principles. This way, the reader will understand the key importance of mathematics applied to all the subjects. Simple models are emphasized and solved with numerous examples. For more sophisticated and advanced models the numerical techniques are described and developed carefully. This book will serve as a synoptic compendium of the fundamentals of fluid, solute and heat transport, applicable to all types of subsurface systems, ranging from shallow aquifers down to deep geothermal reservoirs. The book will prove to be a useful textbook to senior undergraduate and graduate students, postgraduates, professional geologists and geophysicists, engineers, mathematicians and others working in the vital areas of groundwater and geothermal resources.

Download or read book Irrigation Management Transfer written by Carlos Garces-Restrepo and published by Fao. This book was released on 2007 with total page 88 pages. Available in PDF, EPUB and Kindle. Book excerpt: The present water report is the final product emanating from efforts by FAO, IWMI and others to document and understand the implications of the irrigation sector embarking on a wide reform process. It is intended to be a knowledge synthesis document that captures the global experiences emerging from a wide-reaching process targeting the reform of the irrigation sector. This study indicates that irrigation management transfer (IMT) is an approach for irrigation sector reform with the potential to improve the sustainability of irrigation systems. The process requires inter alia strong political commitment, negotiations among stakeholders, and long-term capacity development. Irrigation management transfer should not be seen as a process that has a clear "beginning" and "end". While the former can be more easily identified, the latter is much more difficult to determine. In fact, IMT can be the initial stage of an evolving long reform process. The accompanying CD-ROM contains IMT country profiles and case studies, an international IMT e-mail conference, a bibliography and links.--Publisher's description.

Download or read book Integrated Water Resources Management in Practice written by Roberto Lenton and published by Routledge. This book was released on 2012-08-21 with total page 249 pages. Available in PDF, EPUB and Kindle. Book excerpt: Better water management will be crucial if we are to meet many of the key challenges of this century - feeding the worlds growing population and reducing poverty, meeting water and sanitation needs, protecting vital ecosystems, all while adapting to climate change. The approach known as Integrated Water Resources Management (IWRM) is widely recognized as the best way forward, but is poorly understood, even within the water sector. Since a core IWRM principle is that good water management must involve the water users, the understanding and involvement of other sectors is critical for success. There is thus an urgent need for practical guidance, for both water and development professionals, based on real world examples, rather than theoretical constructs. That is what this book provides. Using case studies, the book illustrates how better water management, guided by the IWRM approach, has helped to meet a wide range of sustainable development goals. It does this by considering practical examples, looking at how IWRM has contributed, at different scales, from very local, village-level experiences to reforms at national level and beyond to cases involving trans-boundary river basins. Using these on-the-ground experiences, from both developed and developing countries in five continents, the book provides candid and practical lessons for policy-makers, donors, and water and development practitioners worldwide, looking at how IWRM principles were applied, what worked, and, equally important, what didn‘t work, and why.

Download or read book Dams and Reservoirs Societies and Environment in the 21st Century written by Luis Berga and published by Taylor & Francis. This book was released on 2006-02-15 with total page 1373 pages. Available in PDF, EPUB and Kindle. Book excerpt: Water resources stored by dams and reservoirs play an essential role in water resource management, hydropower and flood control. Where there is an extensive network of dam infrastructures, dams have made a major contribution to economic and social development, providing considerable storage capacity per capita. However, dams and reservoirs may also have an important social and environmental impact, and should be studied within the framework of integrated water resource management and sustainable development. Dams and Reservoirs, Societies and Environment in the 21st Century presents the latest research on the role played by dams and reservoirs in 21st century societies, in developed, emergent and developing countries. It analyses the viability of dams and suggests alternative solutions from a holistic perspective, considering the technical, economic, social and environmental aspects. Other issues covered include the social acceptability of dams, public involvement and dam awareness. The book covers subjects ranging from dam engineering, through the benefits and drawbacks of dams, to their social and environmental impact, and contains numerous case studies of the constructive contributions that reservoirs have made to water development and management. The book is a valuable resource for professional and dam engineers, water managers, governmental organizations and commercial enterprises responsible for dam development and management.
