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

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.

Organisms and environment have evolved through modifying each other over millions of years. Humans appeared very late in this evolutionary time scale. With their superior brain attributes, humans emerged as the most dominating influence on the earth. Over the millennia, from simple hunter-food gatherers, humans developed the art of agriculture, domestication of animals, identification of medicinal plants, devising hunting and fishing techniques, house building, and making clothes. All these have been for better adjustment, growth, and survival in otherwise harsh and hostile surroundings and climate cycles of winter and summer, and dry and wet seasons. So humankind started experimenting and acting on ecological lines much before the art of reading, writing, or arithmetic had developed. Application of ecological knowledge led to development of agriculture, animal husbandry, medicines, fisheries, and so on. Modem ecology is a relatively young science and, unfortunately, there are so few books on applied ecology. The purpose of ecology is to discover the principles that govern relationships among plants, animals, microbes, and their total living and nonliving environmental components. Ecology, however, had remained mainly rooted in botany and zoology. It did not permeate hard sciences, engineering, or industrial technologies leading to widespread environmental degradation, pollution, and frequent episodes leading to mass deaths and diseases.
