Ecological Aquaculture


Book Description

As the world's demand for food from aquatic environments continues to increase, the importance of performing aquaculture in an environmentally responsible manner also increases. The aim of this important and thought-provoking book is to stimulate discussion among aquaculture's modern scientific, education and extension communities concerning the principles, practices and policies needed to develop ecologically and socially sustainable aquaculture systems worldwide. Ecological Aquaculture provides fascinating and valuable insights into primitive (and often sustainable) culture systems, and ties these to modern large-scale aquaculture systems. The book is edited, and authored to a considerable degree, by Barry Costa-Pierce who has assembled a team of some of the leading thinkers in the field, providing information spanning a spectrum of activities from artisanal to high technology approaches to producing aquatic organisms in a balanced and environmentally-friendly way. Ecological Aquaculture is an essential purchase for all aquaculture personnel involved in commercial, practical and research capacities. Libraries in research establishments and universities where aquaculture, biological, environmental and aquatic sciences are studied and taught should have copies of this book available on their shelves.




A History of Farming Systems Research


Book Description

This book provides a detailed history of farming systems research (FSR). While it includes the application of FSR to developed country agriculture, its main focus is on FSR in its original role, with small scale, resource-poor farmers in less developed countries. There are some 40 contributions from nearly 50 contributors from 20 countries, illustrating both the diversity and yet the coherence of FSR. The five parts of the book cover: (1) FSR - understanding farmers and their farming (FSR origins and perspectives; understanding farming systems); (2) the applications of farming systems research (FSR in technology choice and development; FSR in extension and policy formulation); (3) institutional commitment to FSR (FSR: some institutional experiences in national agricultural research; dimensions of the organization of FSR; training for FSR); (4) FSR: the professional dimension (regional and international associations; FSR and the professional disciplines); and (5) cutting edge methods, abiding issues and the future for FSR.

Feeding a Hungry Planet


Book Description

Rice is the food crop the world depends on most. In Feeding a Hungry Planet, James Lang demonstrates how research has benefited rice growers and increased production. He describes the life cycle of a rice crop and explains how research is conducted and how the results end up growing in a farmer's field. Focusing on Asia and Latin America, Lang explores lowland and upland rice systems, genetics, sustainable agriculture, and efforts to narrow the gap between yields at research stations and those on working farms. Ultimately, says Lang, the ability to feed growing populations and protect fragile ecologies depends as much on the sustainable on-site farm technologies as on high-yielding crop varieties. Lang views agriculture as a chain of events linking the farmer's field with the scientist's laboratory, and he argues that rice cultivation is shaped by different social systems, cultures, and environments. Describing research conducted by the International Rice Research Institute in the Philippines and by the International Center for Tropical Agriculture in Colombia, he shows how national programs tailor research to their own production problems. According to Lang, the interaction of research programs, practical problem solving, and local extension efforts suggests a new model for international development.
