Integrated Agriculture-aquaculture
This document is an edited and slightly revised version of a previously published integrated agriculture-aquaculture (IAA) technology information kit. It contains 38 contributions in seven sections, outlining the basic issues and characteristics of IAA systems and making generous use of pictorial drawings and visual representations.
Rural Aquaculture
Aquaculture for both finfish and shellfish is expanding rapidly throughout the world. It is regarded as having the potential to provide a valuable source of protein in less developed countries and to be integrated into the farming systems and livelihoods of the rural poor. This book addresses key issues in aquaculture and rural development, with case studies drawn from several countries in South and South-East Asia. Papers included cover topics ranging from production and technical issues (such as pond culture and rice field fisheries) to social aspects and research and development methodology. The book has been developed from a meeting of the Asian Fisheries Society. It is aimed at all concerned with aquaculture and rural development.
Farming Systems and Poverty
A joint FAO and World Bank study which shows how the farming systems approach can be used to identify priorities for the reduction of hunger and poverty in the main farming systems of the six major developing regions of the world.
Assessment of Soil Nutrient Balance
Nutrient-balance assessments are valuable tools for delineating the consequences of farming on soil fertility. Various approaches and methods for different situations have been used in the past. This bulletin presents a state-of-the-art review of nutrient balance studies. It brings out the evolution of the approaches and methods, provides for comparisons among them, features the improvements made, and highlights remaining issues. This analysis will be useful in further development of the assessment methodologies as reliable tools for devising time-scale soil fertility management interventions.
Sustainable Aquaculture
Aquaculture is a rapidly growing, successful approach to improving diets by providing more high quality fish and shellfish protein. It is also an industry with major unresolved issues because of its negative impact on the environment. This book is a pioneering effort in the development of environmentally benign aquaculture methods.

Geosystems
Among the most highly regarded in physical geography, Robert Christopherson's bestselling texts are known for meticulous attention to detail, currency, accuracy, rich integration of climate change science, and strong multimedia programs. Geosystems: An Introduction to Physical Geography, Eighth Edition is organized around the natural flow of energy, materials, and information, presenting subjects in the same sequence in which they occur in nature-an organic, holistic approach that is unique in this discipline. Each chapter also includes strong pedagogical tools and a structured learning path, with Key Learning Concepts presented at the start of the chapter, Key Learning Concepts Review at the end of the chapter, and Critical Thinking questions integrated throughout.
