Continued population growth, rapidly changing consumption patterns and the impacts of climate change and environmental degradation are driving limited resources of food, energy, water and materials towards critical thresholds worldwide. These pressures are likely to be substantial across Africa, where countries will have to find innovative ways to boost crop and livestock production to avoid becoming more reliant on imports and food aid. Sustainable agricultural intensification - producing more output from the same area of land while reducing the negative environmental impacts - represents a solution for millions of African farmers. This volume presents the lessons learned from 40 sustainable agricultural intensification programmes in 20 countries across Africa, commissioned as part of the UK Government's Foresight project. Through detailed case studies, the authors of each chapter examine how to develop productive and sustainable agricultural systems and how to scale up these systems to reach many more millions of people in the future. Themes covered include crop improvements, agroforestry and soil conservation, conservation agriculture, integrated pest management, horticulture, livestock and fodder crops, aquaculture, and novel policies and partnerships.

The world is now on the cusp of a new agricultural revolution, the so-called Gene Revolution, in which genetically modified (GM) crops are tailored to address chronic agricultural problems in certain regions of the world. This monograph report investigates the circumstances and processes that can induce and sustain this new agricultural revolution. The authors compare the Green Revolution of the 20th century with the GM crop movement to assess the agricultural, technological, sociological, and political differences between the two movements.

The book offers a rich toolkit of relevant, adoptable ecosystem-based practices that can help the world's 500 million smallholder farm families achieve higher productivity, profitability and resource-use efficiency while enhancing natural capital.

'The Green Revolution' of the 60's and 70's produced immense gains in food cereal production in the Third World. But there are huge problems in the 'post-revolutionary' era: farmers with small or marginal holdings have benefited less than wealthier farmers; intensive mono-cropping has made production more susceptible to environmental stresses and shocks. Now there is evidence of diminishing returns from intensive and intensively chemical agricultural production. What is needed is a new approach, equally revolutionary, but different in its ideas and style. The authors set out what they mean by 'sustainable' agriculture in the new era and look at the effects of international economic restraints and of national policies on the kind of development they see as necessary. They chart a path for sustainable livelihoods for Third World farmers enmeshed by forces outside their control. They describe methods of evaluating and resolving the tough trade-offs all levels of intervention, from international trade down to the individual farm. This book cannot provide all the answers, but it does indicate what international conditions we need to be aware of, what national policies we need to advocate and what approaches at the local level we need to adopt to ensure the goal of agricultural sustainability.

Today more than three quarters of a billion people go hungry in a world where food is plentiful. A distinguished scientist here sets out an agenda for addressing this situation. Initially published in 1997 in the United Kingdom, the book is now available in the first edition produced for the Western hemisphere. In it, the author has updated information to reflect current economic indicators. This volume includes a foreword written for the previous edition by Ismail Serageldin of the World Bank. The original Green Revolution produced new technologies for farmers, creating food abundance. A second transformation of agriculture is now required—specifically, Gordon Conway argues, a "doubly green" revolution that stresses conservation as well as productivity. He calls for researchers and farmers to forge genuine partnerships in an effort to design better plants and animals. He also urges them to develop (or rediscover) alternatives to inorganic fertilizers and pesticides, improve soil and water management, and enhance earning opportunities for the poor, especially women.
