Book Description
The pump design offered in this manual has evolved from the Bangladesh original into a fully portable pump with both lift and pressure capacity; and is especially appropriate to situations where soils are permeable, and water cannot easily be distributed through channels.

Book Description
An “exciting” new approach to lifting people out of poverty that rejects the ineffective top-down mindset (Steve Wozniak, confounder of Apple Computer). Based on his twenty-five years of experience, Paul Polak explodes what he calls the “Three Great Poverty Eradication Myths”: that we can donate people out of poverty; that national economic growth will end poverty; and that big business, operating as it does now, will end poverty. Polak shows that programs based on these ideas have utterly failed—in fact, in sub-Saharan Africa, poverty rates have actually gone up. These failed top-down efforts contrast sharply with the grassroots approach Polak and his organization International Development Enterprises have championed: helping the dollar-a-day poor earn more money through their own efforts. Amazingly enough, unexploited market opportunities do exist for the desperately poor. Polak describes how he and others have identified these opportunities—and have developed innovative, low-cost tools that have helped in lifting seventeen million people out of poverty.

Book Description
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.

Book Description
The report begins with an overview of the challenges on agricultural systems to make more food available and accessible and lays out the potential of irrigation to make agriculture more productive, efficient and profitable for smallholder farmers. A discussion on the potential to expand irrigation across Africa and barriers to uptake including an analysis of the inherent risks and desired outcomes of irrigation forms the next section. The report reviews the traditional and new, innovative smallscale and large-scale irrigation approaches and technologies that have been implemented in Africa, followed by an analysis of the experiences of six African countries that have been particularly innovative and successful in terms of their institutional and policy design for irrigation. The report closes by drawing some key lessons and offering nine recommendations for actions by African governments and the private sector.
