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."

Book Description
Africa is one continent severely affected by the ravaging effects of global environment change yet it is least responsible for this. The continent's rural and urban poor are particularly vulnerable to reduced agricultural production, worsening food security, increased incidence of both flooding and drought, spreading of disease and heightening risk of conflict over scarce land and water resources. As such this timely book consisting of chapters authored by scholars from multidisciplinary backgrounds provides the reader a variety of contexts from which to understand the impacts of global environmental change and how affected African communities are adapting an mitigating the scourge. In addition it discusses different models for mitigation and adaptation applicable to local contexts.

Book Description
Green technology is focused on devising environmentally-friendly (eco-friendly) agricultural practices. It plays a crucial role in dealing with food security issues and reducing the carbon footprint. Green technologies and environmental sustainability are focused on the goals of green technologies, which are becoming increasingly important for ensuring sustainability. The Handbook of Research on Green Technologies for Sustainable Management of Agricultural Resources covers the applications of green technology as well as different eco-friendly technologies for the sustainable management of natural resources. It also explores the timely topic of enhancing crop productivity. It is ideal for agriculturists, farmers, botanists, technologists, policymakers, scientists, academicians, researchers, and students as it covers a variety of concepts such as organic farming and the role of green technologies.

Book Description
There is an urgent need to increase agricultural productivity in sub-Saharan Africa in a sustainable and economically-viable manner. Transforming risk-averse smallholders into business-oriented producers that invest in producing surplus food for sale provides a formidable challenge, both from a technological and socio-political perspective. This book addresses the issue of agricultural intensification in the humid highland areas of Africa – regions with relatively good agricultural potential, but where the scarce land resources are increasingly under pressure from the growing population and from climate change. In addition to introductory and synthesis chapters, the book focuses on four themes: system components required for agricultural intensification; the integration of components at the system level; drivers for adoption of technologies towards intensification; and the dissemination of complex knowledge. It provides case studies of improved crop and soil management for staple crops such as cassava and bananas, as well as examples of how the livelihoods of rural people can be improved. The book provides a valuable resource for researchers, development actors, students and policy makers in agricultural systems and economics and in international development. It highlights and addresses key challenges and opportunities that exist for sustainable agricultural intensification in the humid highlands of sub-Saharan Africa.
