Download or read book A History of Farming Systems Research written by Michael P. Collinson and published by Food & Agriculture Org.. This book was released on 2000 with total page 452 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides a detailed history of farming systems research (FSR). While it includes the application of FSR to developed country agriculture, its main focus is on FSR in its original role, with small scale, resource-poor farmers in less developed countries. There are some 40 contributions from nearly 50 contributors from 20 countries, illustrating both the diversity and yet the coherence of FSR. The five parts of the book cover: (1) FSR - understanding farmers and their farming (FSR origins and perspectives; understanding farming systems); (2) the applications of farming systems research (FSR in technology choice and development; FSR in extension and policy formulation); (3) institutional commitment to FSR (FSR: some institutional experiences in national agricultural research; dimensions of the organization of FSR; training for FSR); (4) FSR: the professional dimension (regional and international associations; FSR and the professional disciplines); and (5) cutting edge methods, abiding issues and the future for FSR.

Download or read book The Political Economy of Soil Erosion in Developing Countries written by Piers Blaikie and published by Routledge. This book was released on 2016-05-20 with total page 201 pages. Available in PDF, EPUB and Kindle. Book excerpt: First published in 1985. This book examines wide variety of ways in which environmental deterioration, in particular soil erosion, can be viewed and the implicit political judgements that often inform them. Using the context of developing countries, where the effects tend to be more acute due to underdevelopment and climatic factors, this work aims to examine this source of uncertainty and make explicit the underlying assumptions in the debate about soil erosion. It also rejects the notion that soil erosion is a politically neutral issue and argues that conservation requires fundamental social change. This title will be of interest to students of environmental and developmental studies.

Download or read book Marine and Coastal Protected Areas written by Rodney V. Salm and published by IUCN. This book was released on 2000 with total page 406 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is a new edition of the classic textbook on marine protected area (MPA) management in the tropics, originally produced as an output of the Bali World Parks Congress in 1982. Approaches to planning and managing MPAs have evolved considerably. Major advances include innovative financing mechanisms, partnerships with the private sector and NGOs, and collaborative management between government and coastal communities. These advances have brought new approaches for MPA establishment and management that are more participatory, involving communities through interaction and collaboration rather than prescription. With new case studies and illustrations, the guide comes in a water-resistant cover for field use. It is intended for those who plan individual and/or national MPA systems and gives philosophical context for MPAs along with some basic principles and approaches.

Download or read book Farming Systems and Food Security in Africa written by John Dixon and published by Routledge. This book was released on 2019-12-09 with total page 896 pages. Available in PDF, EPUB and Kindle. Book excerpt: Knowledge of Africa’s complex farming systems, set in their socio-economic and environmental context, is an essential ingredient to developing effective strategies for improving food and nutrition security. This book systematically and comprehensively describes the characteristics, trends, drivers of change and strategic priorities for each of Africa’s fifteen farming systems and their main subsystems. It shows how a farming systems perspective can be used to identify pathways to household food security and poverty reduction, and how strategic interventions may need to differ from one farming system to another. In the analysis, emphasis is placed on understanding farming systems drivers of change, trends and strategic priorities for science and policy. Illustrated with full-colour maps and photographs throughout, the volume provides a comprehensive and insightful analysis of Africa’s farming systems and pathways for the future to improve food and nutrition security. The book is an essential follow-up to the seminal work Farming Systems and Poverty by Dixon and colleagues for the Food and Agriculture Organization (FAO) of the United Nations and the World Bank, published in 2001.

Download or read book Advances in Groundwater Governance written by Karen G. Villholth and published by CRC Press. This book was released on 2017-12-14 with total page 621 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book addresses groundwater governance, a subject internationally recognized as crucial and topical for enhancing and safeguarding the benefits of groundwater and groundwater-dependent ecosystems to humanity, while ensuring water and food security under global change. The multiple and complex dimensions of groundwater governance are captured in 28 chapters, written by a team of leading experts from different parts of the world and with a variety of relevant professional backgrounds. The book aims to describe the state-of-the-art and latest developments regarding each of the themes addressed, paying attention to the wide variation of conditions observed around the globe. The book consists of four parts. The first part sets the stage by defining groundwater governance, exploring its emergence and evolution, framing it through a socio-ecological lens and describing groundwater policy and planning approaches. The second part discusses selected key aspects of groundwater governance. The third part zooms in on the increasingly important linkages between groundwater and other resources or sectors, and between local groundwater systems and phenomena or actions at the international or even global level. The fourth part, finally, presents a number of interesting case studies that illustrate contemporary practice in groundwater governance. In one volume, this highly accessible text not only familiarizes water professionals, decision-makers and local stakeholders with groundwater governance, but also provides them with ideas and inspiration for improving groundwater governance in their own environment.

Download or read book The Ganges River Basin written by Luna Bharati and published by Routledge. This book was released on 2016-08-25 with total page 452 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Ganges is one of the most complex yet fascinating river systems in the world. The basin is characterized by a high degree of heterogeneity from climatic, hydrological, geomorphological, cultural, environmental and socio-economic perspectives. More than 500 million people are directly or indirectly dependent upon the Ganges River Basin, which spans China, Nepal, India and Bangladesh. While there are many books covering one aspect of the Ganges, ranging from hydrology to cultural significance, this book is unique in presenting a comprehensive inter-disciplinary overview of the key issues and challenges facing the region. Contributors from the three main riparian nations assess the status and trends of water resources, including the Himalayas, groundwater, pollution, floods, drought and climate change. They describe livelihood systems in the basin, and the social, economic, geopolitical and institutional constraints, including transboundary disputes, to achieving productive, sustainable and equitable water access. Management of the main water-use sectors and their inter-linkages are reviewed, as well as the sustainability and trade-offs in conservation of natural systems and resource development such as for hydropower or agriculture.

Download or read book Marine Biodiversity of Costa Rica Central America written by Ingo S. Wehrtmann and published by Springer Science & Business Media. This book was released on 2008-12-28 with total page 545 pages. Available in PDF, EPUB and Kindle. Book excerpt: Life began in the sea, and even today most of the deep diversity of the planet is marine. This is often forgotten, especially in tropical countries like Costa Rica, renowned for their rain forests and the multitude of life forms found therein. Thus this book focusing on marine diversity of Costa Rica is particularly welcome. How many marine species are there in Costa Rica? The authors report a total of 6,777 species, or 3. 5% of the world’s total. Yet the vast majority of marine species have yet to be formally described. Recent estimates of the numbers of species on coral reefs range from 1–9 million, so that the true number of marine species in Costa Rica is certainly far higher. In some groups the numbers are likely to be vastly higher because to date they have been so little studied. Only one species of nematode is reported, despite the fact that it has been said that nematodes are the most diverse of all marine groups. In better studied groups such as mollusks and crustaceans, reported numbers are in the thousands, but even in these groups many species remain to be described. Indeed the task of describing marine species is daunting – if there really are about 9 million marine species and Costa Rica has 3. 5% of them, then the total number would be over 300,000. Clearly, so much remains to be done that new approaches are needed. Genetic methods have en- mous promise in this regard.
