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.

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 In order to reduce such bias, attempts were made to review unpublished "grey" literature as well, although this was by no means comprehensive.

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.

Sustainable Food and Agriculture: An Integrated Approach is the first book to look at the imminent threats to sustainable food security through a cross-sectoral lens. As the world faces food supply challenges posed by the declining growth rate of agricultural productivity, accelerated deterioration of quantity and quality of natural resources that underpin agricultural production, climate change, and hunger, poverty and malnutrition, a multi-faced understanding is key to identifying practical solutions. This book gives stakeholders a common vision, concept and methods that are based on proven and widely agreed strategies for continuous improvement in sustainability at different scales. While information on policies and technologies that would enhance productivity and sustainability of individual agricultural sectors is available to some extent, literature is practically devoid of information and experiences for countries and communities considering a comprehensive approach (cross-sectoral policies, strategies and technologies) to SFA. This book is the first effort to fill this gap, providing information on proven options for enhancing productivity, profitability, equity and environmental sustainability of individual sectors and, in addition, how to identify opportunities and actions for exploiting cross-sectoral synergies. Provides proven options of integrated technologies and policies, helping new programs identify appropriate existing programs Presents mechanisms/tools for balancing trade-offs and proposes indicators to facilitate decision-making and progress measurement Positions a comprehensive and informed review of issues in one place for effective education, comparison and evaluation

Fish have been a major component of our diet and it has been suggested that fish/seafood consumption contributed to the development of the human brain, and this together with the acquisition of bipedalism, perhaps made us what we are. In the modern context global fish consumption is increasing. However, unlike our other staples, until a few years back the greater proportion of our fish supplies were of a hunted origin. This scenario is changing and a greater proportion of fish we consume now is of farmed origin. Aquaculture, the farming of waters, is thought to have originated in China, many millennia ago. Nevertheless, it transformed into a major food sector only since the second half of the last century, and continues to forge ahead, primarily in the developing world. China leads the global aquaculture production in volume, in the number of species that are farmed, and have contributed immensely to transforming the practices from an art to a science. This book attempts to capture some of the key elements and practices that have contributed to the success of Chinese aquaculture. The book entails contributions from over 100 leading experts in China, and provides insights into some aquaculture practices that are little known to the rest of the world. This book will be essential reading for aquaculturists, practitioners, researchers and students, and planners and developers.
