Although integrated agriculture - aquaculture (IAA) farming has been practiced in Asia for centuries and offers efficient resource utilization, reduces risk by diversifying crops, and provides additional food and income, reliable quantitative production and management guidelines have yet to be produced and disseminated for use as a basis for development programs. This report on the proceedings of the Fourth International Center for Living Aquatic Resources Management Conference (ICLARM 4) addresses this need. The conference was held 6 - 9 August 1979 in Manila, Philippines and was co - sponsored by ICLARM and the Southeast Asian Regional Center for Graduate Study and Research in Agriculture. The conference's goals were to: (1) provide an overview of current IAA farming practices in selected Asian countries; (2) increase awareness of IAA's ability to raise farm income; (3) review available experience and technology; (4) discuss IAA's socioeconomic aspects in order to identify research and development priorities; and (5) encourage governments and international donors to initiate IAA research and development projects. The report consists of 24 papers, 10 of which review broad strategies, techniques, and problems associated with IAA, such as aquaculture in rice fields and irrigation systems; the role of pesticides and health as constraining factors; and the use of animal wastes in pond management. The other 13 papers were presented as case studies on current IAA practices in Hong Kong, Hungary, India, Indonesia, Japan, Malaysia, Nepal, the Philippines, Taiwan, and Thailand. A final paper highlights the needs for research on both IAA farming systems in general and on the major factors affecting IAA performance - energy, materials, space, time, and information. Many of the papers are detailed studies, supported by charts, data, pictures, diagrams, and maps; and most are referenced with bibliographies on sources of information on IAA. A list of the authors and of the conference participants is appended.
