This book was released on 2013-11-11 with total page 235 pages. Available in PDF, EPUB and Kindle. Book excerpt: Research was carried out in Udorn Thani beginning in September, 1975, in order to elucidate the effects of seasonal changes on the aquatic community of a rice field. Physical and chemical changes that occur during the course of a year were recorded and related to the structure and activity of the aquatic biological com munity. A rice field was selected that is typical of the countless habitats of this kind that are found in Northeastern Thailand (Fig. 1). For a variety of reasons these habitats and their location are of special interest (Fig. 2). Figure 1. The rice field investigated, north of the province capital, Udorn Thani, Thailand. Northeastern Thailand and a small part of Laos comprise the middle Mekong Valley. Its geographic situation and climatic conditions set this area apart as a dis tinct sub-region of Southeast Asia. It is unfortunate that sufficient biological research has not yet been carried out to delimit the SUb-regions according to their fauna and flora and to fully describe the various ecosystems that occur in them. The middle Mekong Valley is one of the most neglected areas of the region, and there is no comprehensive literature on its biota. Very little ecological information is available on many of the species that abound there.
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 In order to reduce such bias, attempts were made to review unpublished "grey" literature as well, although this was by no means comprehensive.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 Rural Aquaculture written by Peter Edwards and published by CABI. This book was released on 2002 with total page 382 pages. Available in PDF, EPUB and Kindle. Book excerpt: Aquaculture for both finfish and shellfish is expanding rapidly throughout the world. It is regarded as having the potential to provide a valuable source of protein in less developed countries and to be integrated into the farming systems and livelihoods of the rural poor. This book addresses key issues in aquaculture and rural development, with case studies drawn from several countries in South and South-East Asia. Papers included cover topics ranging from production and technical issues (such as pond culture and rice field fisheries) to social aspects and research and development methodology. The book has been developed from a meeting of the Asian Fisheries Society. It is aimed at all concerned with aquaculture and rural development.

Available in PDF, EPUB and Kindle. Book excerpt: Ecology is an attempt to understand the reciprocal relationship between living and nonliving elements of the earth. For years, however, the discipline either neglected the human element entirely or presumed its effect on natural ecosystems to be invariably negative. Among social scientists, notably in geography and anthropology, efforts to address this human-environment interaction have been criticized as deterministic and mechanistic. Bridging the divide between social and natural sciences, the contributors to this book use a more holistic perspective to explore the relationships between humans and their environment. Exploring short- and long-term local and global change, eighteen specialists in anthropology, geography, history, ethnobiology, and related disciplines present new perspectives on historical ecology. A broad theoretical background on the material factors central to the field is presented, such as anthropogenic fire, soils, and pathogens. A series of regional applications of this knowledge base investigates landscape transformations over time in South America, the Mississippi Delta, the Great Basin, Thailand, and India. The contributors focus on traditional societies where lands are most at risk from the incursions of complex, state-level societies. This book lays the groundwork for a more meaningful understanding of humankind's interaction with its biosphere. Scholars and environmental policymakers alike will appreciate this new critical vocabulary for grasping biocultural phenomena.

Download or read book White Gold The Commercialisation of Rice Farming in the Lower Mekong Basin written by Rob Cramb and published by Springer Nature. This book was released on 2020-01-03 with total page 462 pages. Available in PDF, EPUB and Kindle. Book excerpt: This open access book is about understanding the processes involved in the transformation of smallholder rice farming in the Lower Mekong Basin from a low-yielding subsistence activity to one producing the surpluses needed for national self-sufficiency and a high-value export industry. For centuries, farmers in the Basin have regarded rice as “white gold”, reflecting its centrality to their food security and well-being. In the past four decades, rice has also become a commercial crop of great importance to Mekong farmers, augmenting but not replacing its role in securing their subsistence. This book is based on collaborative research to (a) compare the current situation and trajectories of rice farmers within and between different regions of the Lower Mekong, (b) explore the value chains linking rice farmers with new technologies and input and output markets within and across national borders, and (c) understand the changing role of government policies in facilitating the on-going evolution of commercial rice farming. An introductory section places the research in geographical and historical context. Four major sections deal in turn with studies of rice farming, value chains, and policies in Northeast Thailand, Central Laos, Southeastern Cambodia, and the Mekong Delta. The final section examines the implications for rice policy in the region as a whole.

Download or read book Drought phenotyping in crops From theory to practice written by Philippe Monneveux and published by Frontiers E-books. This book was released on 2014-02-12 with total page 238 pages. Available in PDF, EPUB and Kindle. Book excerpt: This topic is a unique attempt to simultaneously tackle theoretical and practical aspects in drought phenotyping, through both crop-specific and cross-cutting approaches. It is designed for – and will be of use to – practitioners and postgraduate students in plant science, who are grappling with the challenging task of evaluating germplasm performance under different water regimes. In Part I, different methodologies are presented for accurately characterising environmental conditions, implementing trials, and capturing and analysing the information this generates, regardless of the crop. Part II presents the state-of-art in research on adaptation to drought, and recommends specific protocols to measure different traits in major food crops (focusing on particular cereals, legumes and clonal crops). The topic is part of the CGIAR Generation Challenge Programme’s efforts to disseminate crop research information, tools and protocols, for improving characterisation of environments and phenotyping conditions. The goal is to enhance expertise in testing locations, and to stimulate the development and use of traits related to drought tolerance, as well as innovative protocols for crop characterisation and breeding.

Available in PDF, EPUB and Kindle. Book excerpt: Water protection, food production and ecosystem health are worldwide issues. Changes in the global water cycle are affecting human well-being in many places, while widespread land and ecosystem degradation, driven by poor agricultural practices, is seriously limiting food production. Understanding the links between ecosystems, water, and food production is important to the health of all three, and sustainably managing these connections is becoming increasingly necessary. This book shows how sustainable ecosystems, especially agroecosystems, are essential for water management and food production.
