Book Description
This is the first of two volumes that together provide a global overview of the impact of agriculture on soil degradation, tracing the most critical drivers like the use and abuse of agrochemicals, mechanization, overgrazing, irrigation, slash and burn agriculture, and the use of plastics. This book covers the main effects of agriculture practices on soil degradation in several countries from Africa, America, Asia, and Oceania, and it elucidates the impact of chemical agents on soil quality, namely, the use of fertilizers, herbicides, pesticides, soil acidification and microplastics pollution. In these continents, a large number of the population depend on agriculture, which sets an enormous pressure on the ecosystems. Divided into 13 chapters, the book offers authoritative contributions about the fundamental soil degradation problems in countries such as Argentina, Australia, Peru and Bolivia, Brazil, Chile, China, Colombia, India, Israel, Kenya, Mexico, South Africa, the United States of America. As soil degradation issues are often linked with biodiversity loss and poverty, readers will also find in this book an important discussion of the different social, economic, political, and environmental aspects contributing to soil quality and sustainable management. Given the breadth and depth of its coverage, the book offers an invaluable source of information for researchers, students, environmental managers and policymakers alike.

Book Description
For developing nations, soil erosion is among the most chronic environmental and economic burdens. Vast amounts of topsoil are washed or blown away from arable land only to accumulate in rivers, reservoirs, harbors, and estuaries, thereby creating a double disaster: a vital resource disappears from where it is desperately needed and is deposited where it is equally unwanted. Despite much rhetoric and effort, little has been done to overcome this problem. Vetiver, a little-known tropical grass, offers one practical and inexpensive way to control erosion on a huge scale in both humid and semi-arid regions. Hedges of this deeply rooted species catch and hold back sediments while the stiff foliage acts as a filter that also slows runoff and keeps moisture on site. This book assesses vetiver's promise and limitations and identifies places where this grass can be deployed without undue environmental risk.

Book Description
ÿDecades of scientific research related to agriculture and natural resource management have brought limited benefits to smallholder farmers, including crop farmers, fishers, livestock keepers and other resource users. Therefore, donors, policymakers and civil society organizations (CSOs), such as farmer organizations and nongovernmental organizations (NGOs), are urging the formal research sector to make its work more useful to smallholder farmers. Many institutions of agricultural research and development are now seeking ways to engage more closely with smallholders in order to conduct research that is more relevant for and accessible to them, and are seeking examples and good practices as sources of learning. Some examples of research that is focused on smallholders and in which the process is co-managed and driven by smallholders can be found in ?informal? research initiatives --specifically, those which are facilitated by CSOs. The purpose of this study was to identify such examples of informal agricultural research and development that could be documented and thus made accessible to formal researchers. This report also describes farmer-led research findings and their dissemination, and analyzes available evidence on the impact of farmer-led approaches to agricultural research and development on rural livelihoods, local capacity to innovate and adapt, and influence on governmental institutions of agricultural research and development.

Faced with the growing problems of climate change, ecosystem degradation, declining agricultural productivity, and uncertain food security, modern agricultural scientists look for potential relief in an ancient practice. Agroforestry, if properly designed, can mitigate greenhouse effects, maintain ecosystem health and biodiversity, provide food sec

Book Description
This book is based on the findings of a long-term (2000-2014) interdisciplinary research project of the University of Hohenheim in collaboration with several universities in Thailand and Vietnam. Titled Sustainable Land Use and Rural Development in Mountainous Areas in Southeast Asia, or the Uplands Program, the project aims to contribute through agricultural research to the conservation of natural resources and the improvement of living conditions of the rural population in the mountainous regions of Southeast Asia. Having three objectives the book first aims to give an interdisciplinary account of the drivers, consequences and challenges of ongoing changes in mountainous areas of Southeast Asia. Second, the book describes how innovation processes can contribute to addressing these challenges and third, how knowledge creation to support change in policies and institutions can assist in sustainably develop mountain areas and people’s livelihoods.

Book Description
This handbook of locally based agricultural practices brings together the best of science and farmer experimentation, vividly illustrating the enormous diversity of shifting cultivation systems as well as the power of human ingenuity. Environmentalists have tended to disparage shifting cultivation (sometimes called 'swidden cultivation' or 'slash-and-burn agriculture') as unsustainable due to its supposed role in deforestation and land degradation. However, a growing body of evidence indicates that such indigenous practices, as they have evolved over time, can be highly adaptive to land and ecology. In contrast, 'scientific' agricultural solutions imposed from outside can be far more damaging to the environment. Moreover, these external solutions often fail to recognize the extent to which an agricultural system supports a way of life along with a society's food needs. They do not recognize the degree to which the sustainability of a culture is intimately associated with the sustainability and continuity of its agricultural system. Unprecedented in ambition and scope, Voices from the Forest focuses on successful agricultural strategies of upland farmers. More than 100 scholars from 19 countries--including agricultural economists, ecologists, and anthropologists--collaborated in the analysis of different fallow management typologies, working in conjunction with hundreds of indigenous farmers of different cultures and a broad range of climates, crops, and soil conditions. By sharing this knowledge--and combining it with new scientific and technical advances--the authors hope to make indigenous practices and experience more widely accessible and better understood, not only by researchers and development practitioners, but by other communities of farmers around the world.
