Download or read book Biodiversity associated with the rice field agroecosystem in Asian countries A brief review written by Channa N. B. Bambaradeniya and published by IWMI. This book was released on 2004 with total page 29 pages. Available in PDF, EPUB and Kindle. Book excerpt: This review is intended to bring together the published information available on the biodiversity associated with the rice field agroecosystem, in countries extending across Asia from Sri Lanka to Japan. The intention is to provide a synthesis that would enable us to better appreciate the environmental services and opportunities for biodiversity conservation offered by rice fields, as the additional benefits and contribution of these major food-producing agroecosystems. Since this review is based mainly on published information in the English language public domain, such limitation of the exercise might result in a bias towards those countries where the published and/or accessible information exists. In order to reduce such bias, attempts were made to review unpublished "grey" literature as well, although this was by no means comprehensive.
Download or read book Agricultural Research for Sustainable Food Systems in Sri Lanka written by Ranjith Premalal De Silva and published by Springer Nature. This book was released on 2020-10-06 with total page 526 pages. Available in PDF, EPUB and Kindle. Book excerpt: Food systems involve a range of activities concerning food production, processing, distribution, marketing and trade, preparation, consumption and disposal. They encompass the path of food from the farm to the dinner table, meeting the food and nutritional needs of a nation. When such systems do so without sacrificing the needs of future generations, they are referred to as “Sustainable Food Systems.” The natural and physical environment, infrastructure, institutions, society and culture, and policies and regulations within which they operate, as well as the technologies they adopt, shape these systems’ outcomes. Making food systems more sustainable is a key priority for all nations, and Sri Lanka is no exception. Food systems deliver optimal performance when the policy and regulatory environment is conducive, institutions are supportive, and a combination of agricultural research investments and an efficient extension system generates the technologies and scientific evidence required for sound policymaking and agenda setting. Further, agricultural research can generate essential findings, technologies and policies for sustainable agricultural development – across disciplines, sectors and stakeholder groups. This book shares valuable insights into research conducted in the broad food and agriculture sectors in Sri Lanka. It also discusses the status quo in related disciplines, and outlines future research directions. Accordingly, it offers a valuable source of reference material for researchers, students, and stakeholders in the food and agriculture sectors, while also highlighting the types of support that policymakers and other decision-makers can provide.
Download or read book Sustainable Agriculture Reviews written by Eric Lichtfouse and published by Springer. This book was released on 2015-07-07 with total page 214 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sustainable agriculture is a rapidly growing field aiming at producing food and energy in a sustainable way for humans and their children. Sustainable agriculture is a discipline that addresses current issues such as climate change, increasing food and fuel prices, poor-nation starvation, rich-nation obesity, water pollution, soil erosion, fertility loss, pest control, and biodiversity depletion. Novel, environmentally-friendly solutions are proposed based on integrated knowledge from sciences as diverse as agronomy, soil science, molecular biology, chemistry, toxicology, ecology, economy, and social sciences. Indeed, sustainable agriculture decipher mechanisms of processes that occur from the molecular level to the farming system to the global level at time scales ranging from seconds to centuries. For that, scientists use the system approach that involves studying components and interactions of a whole system to address scientific, economic and social issues. In that respect, sustainable agriculture is not a classical, narrow science. Instead of solving problems using the classical painkiller approach that treats only negative impacts, sustainable agriculture treats problem sources. Because most actual society issues are now intertwined, global, and fast-developing, sustainable agriculture will bring solutions to build a safer world.
Download or read book The Mekong written by Ian Charles Campbell and published by Academic Press. This book was released on 2009-11-20 with total page 464 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Mekong is the most controversial river in Southeast Asia, and increasingly the focus of international attention. It flows through 6 counties, China, Myanmar, Laos, Thailand, Cambodia and Viet Nam. The 4 downstream countries have formed the Mekong River Commission to promote sustainable development of the river and many of their people depend on it for their subsistence ? it has possible the largest freshwater fishery in the world, and the Mekong waters support rice agriculture in the delta in Viet Nam (which produces about 40% of that country's food) as well as in Cambodia, Laos and Thailand. China is now building the first large mainstream dam on the river, and has proposals for several more. These dams are likely to affect the downstream countries. Several of the downstream countries also have plans for large scale hydropower and irrigation development which could also impact the river. This book will provide a solid overview of the biophysical environment of the Mekong together with a discussion of the possible impacts, biophysical, economic and social, of some possible development scenarios. It is intended to provide a technical basis which can inform the growing political and conservation debate about the future of the Mekong River, and those who depend on it. It is aimed at river ecologists, geographers, environmentalists and development specialists both in the basin and (especially) outside for whom access to this material is most difficult. This book will be the first comprehensive treatment of the Mekong system. The first comprehensive overview of all aspects of the Mekong River system Deals with a regionally critical ecosystem and one under threat The Mekong supports the world's largest freshwater fishery and provides water underpinning a major regional rice paddy system Presents the authoritative findings of the Mekong River Commission's research for a wider audience for the first time outside of limited distribution reports
Download or read book Social Ecological Restoration in Paddy Dominated Landscapes written by Nisikawa Usio and published by Springer. This book was released on 2015-01-20 with total page 311 pages. Available in PDF, EPUB and Kindle. Book excerpt: With a focus on environmentally friendly rice farming, this unique book integrates both ecosystem and human dimensions of ecological restoration to provide strategies to promote sustainable agriculture and rural development. Paddy fields have multiple functions beyond their role of producing rice: They serve as refuge habitats for a range of wildlife that once inhabited floodplain wetlands and contain a number of unique and threatened aquatic species. They also provide various ecosystem services for regional communities such as water retention, erosion control, flood control, fish culture, and educational opportunities. However, rice paddies are threatened worldwide due to the modernization of agriculture and abandonment of farmland caused by depopulation and the aging of rural communities. Therefore, multiple ecological and sociological aspects must be considered in the ecological restoration of paddy fields. This book aims to do so by incorporating various disciplines of natural and social sciences. Strategies for sustainable agriculture are reviewed, including financial incentives for farmers and the use of flagship wildlife species such as the crested ibis (toki) to promote ecological restoration. With the increasing popularity of environmentally friendly rice farming in parts of Asia and the western United States, this book offers model cases for sustainable management of paddy-dominated landscapes.
Download or read book Nature s Matrix written by Ivette Perfecto and published by Earthscan. This book was released on 2009 with total page 257 pages. Available in PDF, EPUB and Kindle. Book excerpt: Landscapes are frequently seen as fragments of natural habitat surrounded by a 'sea' of agriculture. But recent ecological theory shows that the nature of these fragments is not nearly as important for conservation as is the nature of the matrix of agriculture that surrounds them. Local extinctions from conservation fragments are inevitable and must be balanced by migrations if massive extinction is to be avoided. High migration rates only occur in what the authors refer to as 'high quality' matrices, which are created by alternative agroecological techniques, as opposed to the industrial monocultural model of agriculture. The authors argue that the only way to promote such high quality matrices is to work with rural social movements. Their ideas are at odds with the major trends of some of the large conservation organizations that emphasize targeted land purchases of protected areas. They argue that recent advances in ecological research make such a general approach anachronistic and call, rather, for solidarity with the small farmers around the world who are currently struggling to attain food sovereignty.Nature's Matrix proposes a radically new approach to the conservation of biodiversity based on recent advances in the science of ecology plus political realities, particularly in the world's tropical regions.

Download or read book Routledge Handbook of Agricultural Biodiversity written by Danny Hunter and published by Routledge. This book was released on 2017-10-03 with total page 692 pages. Available in PDF, EPUB and Kindle. Book excerpt: The world relies on very few crop and animal species for agriculture and to supply its food needs. In recent decades, there has been increased appreciation of the risk this implies for food security and quality, especially in times of environmental change. As a result, agricultural biodiversity has moved to the top of research and policy agendas. This Handbook presents a comprehensive overview of our current knowledge of agricultural biodiversity in a series of specially commissioned chapters. It draws on multiple disciplines including plant and animal genetics, ecology, crop and animal science, food studies and nutrition, as well as social science subjects which explore the socio-economic, cultural, institutional, legal and policy aspects of agricultural biodiversity. It focuses not only on the core requirements to deliver a sustainable agriculture and food supply, but also highlights the additional ecosystem services provided by a diverse and resilient agricultural landscape and farming practices. The book provides an indispensable reference textbook for a wide range of courses in agriculture, ecology, biodiversity conservation and environmental studies.

Download or read book More Crop Per Drop written by Meredith Giordano and published by IWA Publishing. This book was released on 2007-01-01 with total page 289 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume is an analytical summary and a critical synthesis of research at the International Water Management Institute over the past decade under its evolving research paradigm known popularly as 'more crop per drop'. The research synthesized here covers the full range of issues falling in the larger canvas of water-food-health-environment interface. Besides its immediate role in sharing knowledge with the research, donor, and policy communities, this volume also has a larger purpose of promoting a new way of looking at the water issues within the broader development context of food, livelihood, health and environmental challenges. More crop per drop: Revisiting a research paradigm contrasts the acquired wisdom and fresh thinking on some of the most challenging water issues of our times. It describes new tools, approaches, and methodologies and also illustrates them with practical application both from a global perspective and within the local and regional contexts of Asia and Africa. Since this volume brings together all major research works of IWMI, including an almost exhaustive list of citations, in one single set of pages, it is very valuable not only as a reference material for researchers and students but also as a policy tool for decision-makers and development agencies.
