Book Description
'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.

Book Description
Seeds of Sustainability is a groundbreaking analysis of agricultural development and transitions toward more sustainable management in one region. An invaluable resource for researchers, policymakers, and students alike, it examines new approaches to make agricultural landscapes healthier for both the environment and people. The Yaqui Valley is the birthplace of the Green Revolution and one of the most intensive agricultural regions of the world, using irrigation, fertilizers, and other technologies to produce some of the highest yields of wheat anywhere. It also faces resource limitations, threats to human health, and rapidly changing economic conditions. In short, the Yaqui Valley represents the challenge of modern agriculture: how to maintain livelihoods and increase food production while protecting the environment. Renowned scientist Pamela Matson and colleagues from leading institutions in the U.S. and Mexico spent fifteen years in the Yaqui Valley in Sonora, Mexico addressing this challenge. Seeds of Sustainability represents the culmination of their research, providing unparalleled information about the causes and consequences of current agricultural methods. Even more importantly, it shows how knowledge can translate into better practices, not just in the Yaqui Valley, but throughout the world.

Book Description
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.

Book Description
'Green-Revolution' technologies have transformed the countryside of many less developed countries. This book examines the processes involved in the adoption of these new technologies and their socio-economic impact. It provides an integrated view of the effects of 'Green Revolution' technologies on economic growth and returns, distribution of income and resources, stability of agricultural production and returns and their sustainability in Bangladesh.

Book Description
This book documents frontier knowledge on the drivers of agriculture productivity to derive pragmatic policy advice for governments and development partners on reducing poverty and boosting shared prosperity. The analysis describes global trends and long-term sources of total factor productivity growth, along with broad trends in partial factor productivity for land and labor, revisiting the question of scale economies in farming. Technology is central to growth in agricultural productivity, yet across many parts of the developing world, readily available technology is never taken up. We investigate demand-side constraints of the technology equation to analyze factors that might influence producers, particularly poor producers, to adopt modern technology. Agriculture and food systems are rapidly transforming, characterized by shifting food preferences, the rise and growing sophistication of value chains, the increasing globalization of agriculture, and the expanding role of the public and private sectors in bringing about efficient and more rapid productivity growth. In light of this transformation, the analysis focuses on the supply side of the technology equation, exploring how the enabling environment and regulations related to trade and intellectual property rights stimulate Research and Development to raise productivity. The book also discusses emerging developments in modern value chains that contribute to rising productivity. This book is the fourth volume of the World Bank Productivity Project, which seeks to bring frontier thinking on the measurement and determinants of productivity to global policy makers.

Book Description
The Green Revolution – the apparently miraculous increase in cereal crop yields achieved in the 1960s – came under severe criticism in the 1970s because of its demands for optimal irrigation, intensive use of fertilisers and pesticides; its damaging impact on social structures; and its monoculture approach. The early 1980s saw a concerted approach to many of these criticisms under the auspices of Consultative Group on International Agricultural Research (CGIAR). This book, first published in 1987, analyses the recent achievements of the CGIAR and examines the Green Revolution concept in South America, Asia and Africa, from an ‘ecodevelopment’ standpoint, with particular regard to the plight of the rural poor. The work is characterised by a concern for the ecological and social dimensions of agricultural development,which puts the emphasis on culturally compatible, labour absorbing and environmentally sustainable food production which will serve the long term needs of developing countries.

Book Description
This book outlines a new paradigm, Sustainable Intensification of Crop Production (SICP), which aims to produce more from the same area of land by increasing efficiency, reducing waste, conserving resources, reducing negative impacts on the environment and enhancing the provision of ecosystem services. The use of ecologically based management strategies can increase the sustainability of agricultural production while reducing off-site consequences. The book also highlights the underlying principles and outlines some of the key management practices and technologies – such as minimum soil disturbance; permanent organic soil covers; species diversification; selection of suitable cultivars, planting time, age and spacing; balanced plant nutrition; agro-ecological pest management; efficient water management; careful management of farm machinery; and integrated crop-livestock production – required to implement SICP. The green revolution (by using high-yielding crop varieties, mono-cropping, fertilization, irrigation, and pesticides) has led to enormous gains in food production and improved world food security. In many countries, however, intensive crop production has had negative impacts on production, ecosystems and the larger environment, putting future productivity at risk. In order to meet the projected demands of a growing population expected to exceed 9 billion by 2050, farmers in the developing world must double food production, a challenge complicated by the effects of climate change and growing competition for land, water and energy. This book will be of immense value to all members of the scientific community involved in teaching, research and extension activities concerning sustainable intensification. The material can be used for teaching post-graduate courses, or as a useful reference guide for policy makers.
