"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."

This book focuses on the soil and environmental resources and how to utilize them under Egyptian conditions to achieve tolerance to environmental abiotic stresses, i.e., drought, heat, salt, pollutants, and biotic stresses such as disease resistance. Further, it explores ways to increase productivity, improve the quality of field crops, and reduce the food gap. The application of modern technologies is an essential mechanism for improving crops' productivity through laser, seed technology, mycorrhiza, and biotechnology to enhance the yield of genotypes in sustainable farming systems. Therefore, this book discusses fundamental ways to increase productivity under various environmental circumstances. The book reflects the enormous potential held by horizontal expansion in the newly reclaimed lands in Egypt. Tapping that potential depends on developing crops that are highly tolerant to environmental stresses and mitigating the impacts of climate changes around the world to help Egypt and countries with similar weather and water deficits achieve the 2030 sustainability agenda for agriculture. Given its profundity and scope, the book offers a valuable asset for stakeholders, policy planners, decision-makers, researchers, and scientists in Egypt and worldwide.
