A comprehensive overview of the current state of this highly relevant topic. An interdisciplinary team of researchers reports on the opportunities and challenges of nanotechnology in the agriculture and food sector, highlighting the scientific, technical, regulatory, safety, and societal impacts. They also discuss the perspectives for the future, and provide insights into ways of assuring safety so as to obtain confidence for the consumer, as well as an overview of the innovations and applications.
There has been growing attention to urban agriculture (UA) worldwide because of its role in making cities more sustainable from an environmental perspective while also contributing to the role farming and gardening in the city contribute to social justice. This edited volume brings together current research and case material about urban agriculture from both the Global North (GN) and the Global South (GS). Its objective is to help bridge the long-standing divide between discussion of UA in the GS and GN and to demonstrate that today there are greater areas of overlap than difference both theoretically and substantively and that research in one area can help inform the other. Themes to be included in the book are urban agriculture and how this supports livelihoods, provides ecosystem services and community development; UA and social capital, networks, and agro-biodiversity conservation. The book explains what have we learned regarding UA in one part of the world that may be applicable elsewhere. It also examines, quite fundamentally, why do people farm in the city and how can UA contribute to more sustainable cities in both the GN and GS?
This book critically examines the idea that the sustainability of agriculture could be improved by mimicking the structure and processes occurring in natural ecosystems. Researchers from around the world present comparative studies of multi-species farming systems, natural ecosystems and conventional agriculture. Case studies from Europe, Africa, Asia, Australia, and North and South America examine the implications of increasing the complexity of farming systems on water and nutrient cycling, productivity and resilience. Theoretical issues discussed include the role of biodiversity in agriculture, the trade-off between perenniality and productivity, the choice to integrate or segregate production and conservation in an agricultural landscape, and the social and economic challenges to adopting complex farming systems. One section is devoted to the application of this concept in southern Australia, where 15 million hectares of land are expected to be affected by salinity by the middle of the next century unless there is a significant change in agricultural practice.
