Book Synopsis Green Manure/Cover Crop Systems of Smallholder Farmers by : Marjatta Eilittä
Download or read book Green Manure/Cover Crop Systems of Smallholder Farmers written by Marjatta Eilittä and published by Springer Science & Business Media. This book was released on 2007-05-08 with total page 386 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the 1980s and 1990s, green manure/cover crop (GMCC) systems became a popular agricultural technology in research and development efforts for smallholder tropical and subtropical farmers. However, few syntheses of these experiences have been conducted. This volume of case studies contributes to bridging this gap by reviewing field-level experiences with these systems. Twelve case studies are included. Eleven of them describe experiences from Latin America (4 cases), Africa (6 cases) and Asia (1 case) and the twelfth case reports on the development of a GMCC systems database. Two concluding chapters, `Learning from the Case Studies' and `Future Perspectives', build upon the cases. The systems described are diverse. Some systems have been spontaneously adopted by farmers, while others have been introduced to the farmers through diffusion efforts. Some of the cases reviewed describe small, localized efforts while others report on large-scale, well-known ones, such as the combination of GMCCs and conservation tillage in Santa Catarina, Brazil, the maize-Mucuna system in northern Honduras, and the improved fallow systems in Eastern Zambia. Most experiences include both development and research aspects and to the extent possible the cases integrate these two. Discussion of the strengths and shortcomings of the systems and efforts is frank, and the goal is to learn from these experiences to benefit future efforts. It is expected that both researchers and development practitioners and students of tropical farming systems and soil management will find this volume of case studies useful.
Book Synopsis Conservation Agriculture by : L. García-Torres
Download or read book Conservation Agriculture written by L. García-Torres and published by Springer Science & Business Media. This book was released on 2013-04-17 with total page 506 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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 Synopsis Soil Biology and Agriculture in the Tropics by : Patrice Dion
Download or read book Soil Biology and Agriculture in the Tropics written by Patrice Dion and published by Springer Science & Business Media. This book was released on 2010-02-04 with total page 322 pages. Available in PDF, EPUB and Kindle. Book excerpt: The relationships between soils, microbes and humans are of crucial relevance in the tropics, where plant stress and microbial activity are exacerbated. This volume of Soil Biology presents the living component of tropical soils, showing how it is shaped by environmental conditions and emphasizing its dramatic impact on human survival and well-being. Following an introduction to the specificities of tropical soils and of their microbial communities, the biological aspects of soil management are examined, dealing with land use change, conservation and slash-and-burn agriculture, the restoration of hot deserts, agroforestry and paddy rice cultivation. As they are of particular relevance for tropical agriculture, symbioses of plants and microbes are thoroughly covered, as are the biodegradation of pesticides and health risks associated with wastewater irrigation. Lastly, traditional soil knowledge is discussed as a key to our sustainable presence in this world.

Book Synopsis Savannas and Dry Forests by : Andrea Berardi
Download or read book Savannas and Dry Forests written by Andrea Berardi and published by Routledge. This book was released on 2017-05-15 with total page 294 pages. Available in PDF, EPUB and Kindle. Book excerpt: Parched landscapes, biodiversity loss, encroaching deserts and deforestation are some of the environmental crises taking place in tropical savannas and dry forests throughout the world. To date, much research into these regions has treated humans as 'outside' or as an 'impact' only. However, over and over again, examples show that, in fact, humans are not external factors, but integral components of these systems. Humans are key determinants of savannas and dry forests, affecting patterns and processes, as well as impacts on natural resources. Unless we understand the human-environment relationship in these regions, we will never truly identify the causes or be able to provide solutions. This book therefore focuses on the roles of the past, present and future human perceptions and actions on savannas and dry forests. It examines how the views of local farmers, NGO workers, government officials and international scientists differ on the links between the social and ecological components of savannas. It deals with these multiple perspectives by using systems diagramming and conceptual modelling to provide a clearer and more explicit understanding and to promote better communication between the various actors concerned.

Book Synopsis Mechanization for Rural Development by : Josef Kienzle
Download or read book Mechanization for Rural Development written by Josef Kienzle and published by Food & Agriculture Organization of the UN (FAO). This book was released on 2013 with total page 368 pages. Available in PDF, EPUB and Kindle. Book excerpt: This publication gives a wide-ranging perspective on the present state of mechanization in the developing world, and, as such, constitutes a solid platform on which to build strategies for a sustainable future. Farm mechanization forms an integral plank in the implementation of sustainable crop production intensification methodologies and sustainable intensification necessarily means that the protection of natural resources and the production of ecosystem services go hand-in-hand with intensified production practices. This requires specific mechanization measures to allow crops to be established with minimum soil disturbance, to allow the soil to be protected under organic cover for as long as possible, and to establish crop rotations and associations to feed the soil and to exploit crop nutrients from various soil horizons. This work is the starting point to help the reader understand the complexities and requirements of the task ahead.

Book Synopsis Research Methodology on Data Envelopment Analysis (DEA) by : Jibendu Kumar Mantri
Download or read book Research Methodology on Data Envelopment Analysis (DEA) written by Jibendu Kumar Mantri and published by Universal-Publishers. This book was released on 2008 with total page 379 pages. Available in PDF, EPUB and Kindle. Book excerpt: Data Envelopment Analysis (DEA) represents a milestone in the progression of a continuously advancing methodology for data analysis, which finds extensive use in industry, society and even in education. This book is a handy encyclopedia for researchers, students and practitioners looking for the latest and most comprehensive references in DEA. J.K. Mantri has specifically selected 22 research papers where DEA is applied in different fields so that the techniques discussed in this book can be used for various applications. In A Bibliography of Data Envelopment Analysis (1978-2001), Gabriel Tavares states that DEA is a mathematical programme for measuring performance efficiency of organizations popularly named as decision-making units (DMU). The DMU can be of any kind such as manufacturing units, a number of schools, banks, hospitals, police stations, firms, etc. DEA measures the performance efficiency of these kinds of DMUs, which share a common characteristic: they have a non-profit organization where measurement is difficult. DEA assumes the performance of the DMU using the concepts of efficiency and productivity, which are measured as the ratio of total outputs to total inputs. The efficiencies estimated are relative to the best performing DMU, which is given a score of 100%. The performance of other DMUs varies between 0% and 100%.
