Integrated Irrigation and Aquaculture in West Africa


Book Description

This publication contains background documents and papers presented at a workshop on integrated irrigation aquaculture (IIA), held in Mali in November 2003, as well as the findings of FAO expert missions on IIA in the West Africa region. The rationale for IIA development lies in its potential to increase productivity of scarce freshwater resources and to reduce pressure on natural resources, issues of particular important in the drought-prone countries of West Africa.




Aquaculture


Book Description

This book is divided into three sections. Following the "Introduction", the second section, "Sustainable Aquaculture", offers integrated information on rice cultivation and aquaculture that provide additional benefits to producers. In addition, the participation of aquaculture in the restoration of the Crassostrea virginica fishery is evaluated. The third section, "Homeopathy and Probiotics", is about highly diluted substances and beneficial microorganisms that have proved their effectiveness in human medicine, agronomy, veterinary and currently in the marine aquaculture field. Also, a study focused on the performance of growth and nutrient utilization of the freshwater shrimp Macrobrachium vollenhovenii fed diets supplemented with Lactobacillus acidophilus is presented. This book can be consulted by students, professors and researchers in the area of biological sciences.

Book Description




Fishponds in farming systems


Book Description

"Throughout the last century, specialisation and intensification were buzz words for farmers in the Western world. However, this approach has not resulted in sustainable development as evidenced by the fact that scientists now need to create technologies to reduce negative impacts. In this book we demonstrate that an alternative exists. Case studies from Bangladesh, Thailand, and Vietnam show that integration and diversification increase both farm productivity and farmers’ incomes. By adopting a participatory approach, farmers and scientists identified a range of technologies that strengthen the positive impacts of integrated aquaculture-agriculture systems for the environment. This book is a collection of refereed papers on a controversial subject in agricultural development. Arguing that sustainability of fish culture in ponds needs a new paradigm - feed the pond to grow fish - two chapters focus on nutrient cycling in such systems. Another chapter makes the case for breeding Nile tilapia for resource poor farmers and presents practical options to avoid the pitfalls that arise from natural tilapia mating in low-input ponds. The book contains chapters on livelihood and development aspects and ends with a general discussion completing the picture of the integrated aquaculture-agriculture systems. Overall it composes a review which addresses one of the key issues of the new century: how to sustainably produce food without compromising environmental integrity."




Values at Sea


Book Description

The human impact on vast areas of the oceans remains relatively unregulated. Sometimes, in fact, the only controls over our exploitation of marine resources lie in our environmental consciousness. While the field of environmental ethics has explored rights and duties for land use, stewardship, and policy, relatively little attention has been given to comparable issues of marine environments. Values at Sea makes an important step toward moving environmental ethics discussions into a broader framework. Gathered here are fifteen papers by an interdisciplinary group of scholars, including ethicists, marine scientists, anthropologists, economists, geographers, lawyers, and activists. From the Great Lakes to the Pacific Islands, from the open sea to coastal areas, the papers cover a broad array of ethical issues and policy matters related to such topics as the valuation of marine life, indigenous peoples’ knowledge and environmental stewardship, endemic and exotic species, aquaculture, oil spills, and species protection.
