Conserving Land, Protecting Water by Deborah Bossio,Kim Geheb Pdf
The degradation of land and water resources resulting primarily from agricultural activities has had enormous impact on human society. In order to alleviate this problem an advanced understanding of the state of our resources and the process of degradation is needed. Conserving Land, Protecting Water includes an overview of existing literature focusing on global patterns of land and water degradation and discussions of new insights drawn from successful case studies on reversing soil and water degradation and their impact on food and environmental security.
Soil and Water Conservation by Frederick R. Troeh,James Arthur Hobbs,Roy Luther Donahue Pdf
Written from an agronomic rather than an engineering perspective, this introduction to soil and water conservation explores a full range of topics and environmental issues, including some ignored or overlooked in other books on the subject. Comprehensive, up-to-date, and accessible, it considers the hazards posed by erosion, sedimentation, and pollution, and describes the techniques needed to conserve soil and maintain environmental quality. Situations and examples are drawn from many places to represent a cross-section of the soils, climates and cultures of the world, as well as the full scope of agricultural, engineering, mining, and other uses of the land. The volume covers conserving soil and water, soil erosion and civilization, geologic erosion and sedimentation, water erosion and sedimentation, wind erosion and deposition, predicting soil loss, soil surveys as a basis for land use planning, cropping systems, tillage practices for conservation, conservation structures, vegetating drastically disturbed areas, pastureland, rangeland, and forestland management, water conservation, soil drainage, irrigation and reclamation, soil pollution, water quality and pollution, economics of soil and water conservation, soil and water conservation agencies in the United States, and soil and water conservation around the world. For professionals that deal with soil and water conservation.

Sustaining the Soil by Chris Reij,Ian Scoones,Calmilla Toulmin Pdf
Indigenous soil and water conservation practices are rarely acknowledged in the design of conventional development projects. Instead, the history of soil and water conservation in Africa has been one of imposing external solutions without regard for local practice. There is a remarkably diverse range of locally developed and adapted technologies for the conservation of water and soil, well suited to their particular site and socio-economic conditions. But such measures have been ignored, and sometimes even overturned, by external solutions. Sustaining the Soil documents farmers' practices, exploring the origins and adaptations carried out by farmers over generations, in response to changing circumstances. Through a comparative analysis of conservation measures - from the humid zones of West Africa to the arid lands of the Sudan, from rock terraces in Morocco to the grass strips of Swaziland - the book explores the various factors that influence adoption and adaptation; farmers' perceptions of conservation needs; and the institutional and policy settings most favorable to more effective land husbandry. For the first time on an Africa-wide scale, this book shows that indigenous techniques work, and are being used successfully to conserve and harvest soil and water. These insights combine to suggest new ways forward for governments and agencies attempting to support sustainable land management in Africa, involving a fusion of traditional and modern approaches, which makes the most of both the new and the old.
