Genetic research in some fundamental crops, together with the use of chemicals as pesticides and fertilizers, opened the way in the 1950s and 1960s to great changes in methodology in agriculture - with astonishing results in the tropics. This change became known as the Green Revolution - a truly great revolution in methods and materials which, when applied with intelligence, made possible in a few years the achievement of complete sufficiency in cereals production in South and South East Asia, Mexico and South America. After 20 years of continuous success, aspects of the Green Revolution need to be rediscussed in the light of new findings and possibilities offered by scientific and technological progress - and negative side effects on environment and health. These papers examine the present state of agriculture, and indicate the way forward for its development, especially in the tropics and, in particular, Africa and South America. The need for more research is stressed; priorities in the application of this research are discussed, such as the economic aspects of any new system to be adopted, and the need to respect the ecological equilibria of different environments and the balance of energy input/output in a given agrosystem.

China’s dismantling of the Mao-era rural commune system and return to individual household farming under Deng Xiaoping has been seen as a successful turn away from a misguided social experiment and a rejection of the disastrous policies that produced widespread famine. In this revisionist study, Joshua Eisenman marshals previously inaccessible data to overturn this narrative, showing that the commune modernized agriculture, increased productivity, and spurred an agricultural green revolution that laid the foundation for China’s future rapid growth. Red China’s Green Revolution tells the story of the commune’s origins, evolution, and downfall, demonstrating its role in China’s economic ascendance. After 1970, the commune emerged as a hybrid institution, including both collective and private elements, with a high degree of local control over economic decision but almost no say over political ones. It had an integrated agricultural research and extension system that promoted agricultural modernization and collectively owned local enterprises and small factories that spread rural industrialization. The commune transmitted Mao’s collectivist ideology and enforced collective isolation so it could overwork and underpay its households. Eisenman argues that the commune was eliminated not because it was unproductive, but because it was politically undesirable: it was the post-Mao leadership led by Deng Xiaoping—not rural residents—who chose to abandon the commune in order to consolidate their control over China. Based on detailed and systematic national, provincial, and county-level data, as well as interviews with agricultural experts and former commune members, Red China’s Green Revolution is a comprehensive historical and social scientific analysis that fundamentally challenges our understanding of recent Chinese economic history.

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.

A Planet for Life 2012 focuses on agriculture and its relation to development, food and the environment. At the end of the 2000s, a consensus has emerged and points to the urgent need for massive investment in the agricultural sector, which is (once again) viewed as one of the prime engines for development and food security, as well as for poverty reduction. But what exactly does this consensus cover?While the idea of investing in agriculture is gaining ground and although several countries or regions appear to be offering opportunities for investment in agricultural land, debates are going on as to which agricultural models to choose and how agricultural policies should be implemented.A Planet for Life called on many highly specialized authors from different countries and perspectives, and invites the reader to discover the sector in all its complexity, upstream and downstream of agricultural production.At the crossroads of the challenges posed by development, food security and the environment, the transformation of the agricultural sector is at the heart of the global stakes of sustainable development. To help steer these changes towards greater sustainability, this book makes us aware of how crucial it is to also change our representations of agriculture, change the visions that guide projects for change and the policies regulating this sector.

In what ways can key ural and cultural functions of water, primarily elements of the water balance and the hydrological through direct interference by agriculture and cycle be altered by climate change? To answer this through pollutant loads emanating from point and question, the Council presents an analysis in which non-point sources in settlements, the small business characteristics of the hydrological cycle under pre sector, agriculture and industry.

The latter include use.
