Book Description
Conservation Agriculture is based on soil conservation techniques and the sustainable use of natural resources to increase productivity levels. This case study describes the introduction and promotion of the 'zero tillage' system in a tropical area of Brazil. The publication has been developed as teaching material for agricultural students and practitioners, and it will also be of interest to all those involved in the promotion of conservation agriculture.

Book Description
Sustainability rests on the principle that we must meet the needs of the present without compromising the ability of future generations to meet their own needs. Starving people in poor nations, obesity in rich nations, increasing food prices, on-going climate changes, increasing fuel and transportation costs, flaws of the global market, worldwide pesticide pollution, pest adaptation and resistance, loss of soil fertility and organic carbon, soil erosion, decreasing biodiversity, desertification, and so on. Despite unprecedented advances in sciences allowing to visit planets and disclose subatomic particles, serious terrestrial issues about food show clearly that conventional agriculture is not suited any longer to feed humans and to preserve ecosystems. Sustainable agriculture is an alternative for solving fundamental and applied issues related to food production in an ecological way. While conventional agriculture is driven almost solely by productivity and profit, sustainable agriculture integrates biological, chemical, physical, ecological, economic and social sciences in a comprehensive way to develop new farming practices that are safe and do not degrade our environment. In that respect, sustainable agriculture is not a classical and narrow science. Instead of solving problems using the classical painkiller approach that treats only negative impacts, sustainable agriculture treats problem sources. As most actual society issues are now intertwined, global, and fast-developing, sustainable agriculture will bring solutions to build a safer world. This book gathers review articles that analyze current agricultural issues and knowledge, then propose alternative solutions. It will therefore help all scientists, decision-makers, professors, farmers and politicians who wish to build a safe agriculture, energy and food system for future generations.

Book Description
In large parts of the developed and developing worlds soil tillage by plough or hoe is the main cause of land degradation leading to stagnating or even declining production levels and increasing production cost. It causes the soil to become more dense and compacted, the organic matter content to be reduced and water runoff and soil erosion to increase. It also leads to droughts becoming more severe and the soil becoming less fertile and less responsive to fertiliser. This book brings together the key notes lectures and other outstanding contributions of the I World Congress on Conservation Agriculture and provides an updated view of the environment and economic advantages of CA and of its implementation in diferent areas of the World.

Book Description
The purpose of this publication is to show how conservation agriculture can increase crop production while reducing erosion and reversing soil fertility decline, improving rural livelihoods and restoring the environment in developing countries. Soil organic matter and biological activity in the rooting zone, stimulated by continual additions of fresh organic material (crop residues and cover crops) are the basis of conservation agriculture, as described in the first chapter.

Book Description
Low external-input technology (or LEIT) is an increasingly prominent subject in discussions of sustainable agriculture. There are growing calls for self-sufficient agriculture in an era experiencing diminishing returns from reliance upon expensive synthetic pesticides and fertilizers. There are many reasons to support strategies for low external input farming, including a concern for environmental sustainability, increased attention to resource-poor farmers and marginal environments, and the conviction that a better use of local resources in small-scale agriculture can improve farm productivity and innovation. But despite the increased attention to self-sufficient agriculture, there is little evidence available on the performance and impact of LEIT. This book examines the contributions and limitations of low external input technology for addressing the needs of resource-poor farmers. For the first time a balanced analysis of LEIT is provided, offering in-depth case studies, an analysis of the debates, an extensive review of the literature and practical suggestions about the management and integration of low external input agriculture in rural development programmes.
