"Green Revolution: Cultivating the Future without Soil" is an essential and innovative guide aimed at introducing the reader to the fascinating world of hydroponics and aquaponics, two revolutionary cultivation methods that could redefine the future of agriculture. Hydroponics, which involves growing plants in nutrient-rich water solutions rather than soil, and aquaponics, which integrates plant cultivation with fish farming in a circular system, are explored in detail. The author guides the reader through the fundamental principles of these methods, illustrating how they work, what their advantages are, and how they can contribute to a more sustainable and efficient agriculture. The book also delves into the latest innovations in the field, showcasing how technology is evolving and how new tools and techniques are making these methods even more effective and accessible. From home systems to large-scale commercial setups, "Green Revolution" covers a wide range of applications, providing practical advice and tailored solutions for every need. In addition to technical details, the work emphasizes the importance of sustainable agriculture in a world where resources are becoming scarcer and the population is growing. The author explores how hydroponics and aquaponics can help address some of the greatest challenges of our time, such as food security, water conservation, and reducing the environmental impact of agriculture. Concluding with an overview of strategies to make hydroponic and aquaponic farming not only sustainable but also profitable, "Green Revolution" is an indispensable text for anyone interested in the future of agriculture and who wishes to contribute to a greener and more sustainable world.

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.

This book, which is the result of an intellectual odyssey, began as an attempt to explore and map the environmental and cross-cultural dimensions of the continuing spread of the green revolution-that package of high-yielding varieties of grain, fertilizers, irrigation, and pesticides that constitutes the core of modern industrial agriculture. In the process of traversing the terrain of several intellectual traditions and cutting through various disciplinary forests and thickets, a number of striking observations were made-all leading to two sober ing conclusions. First, most intellectual maps dealing with agriculture fail to recognize it as the basic interface between human societies and their environment. Because of this, they are little better than the "flat earth" maps of earlier centuries in helping to understand global realities. Second, when agriculture is analyzed from a global perspec tive that takes evolution seriously, one sees that the ecological risks as well as the energy and social costs of modern industrial agriculture make it largely inappropriate for developing countries. Beyond that, one can see a great need within industrialized countries to develop less costly, less risky, and more sustainable agricultural alternatives. Early in the journey it became clear that conventional disciplinary approaches were inadequate to comprehend the scope and diversity of global agriculture and that a new multilevel approach was needed. It also became clear that any new approach would have to try to correct certain Western biases and blind spots.

The green revolution in India about 50 years ago transformed India's image then as begging bowl to bread basket. This transformation during the 1960s took just about 4 years. The yield increases achieved in wheat and then in rice which occurred in just about half decade is far in excess of the yield increases during the preceding 4000 years. This remarkable feat was achieved with the leadership of the author using the dwarf wheat types which had been produced by Norman Borlaug in Mexico. The research and development of green revolution of wheat and rice at the Indian Agricultural Research Institute, New Delhi was led by the author along with his team of students and co-workers. He has published over 100 papers on green revolution and the ever-green revolution which is a refinement of the former. This book is a compilation of just about 40 of his numerous research papers, monographs and books published by him on this subject. The papers in this book bring out the scientific basis of the modification of the plant type so as to be responsive to exogenous addition of chemical fertilizers and irrigation. The ideal plant type enables capture of adequate sunlight and using the chemical fertilizers added to the soil, produce substantial photosynthetic starch. And because the plants have short and thick culm, they are able to withstand enormous amounts of grains in their ears. This indeed was the basis of breaking the yield barriers associated with native varieties. The book also brings out that green revolution had established the food security at the national level but not at the individual household levels of millions of resource-poor rural small and marginal farming, fishing and landless families. Further green revolution was commodity-centric and the manner of its practice led to environmental degradation and social inequities. This author realized as early as 1972 that system of agriculture in India should be designed to fight both the famines of food and rural livelihoods. In pursuit of it, this author further designed an evergreen revolution with systems approach. What this means is providing concurrent attention to ecological foundations of agriculture and the livelihoods of the rural people. The book also brings out that green revolution was a team effort involving scientists, policy makers, administrators, farmers and students. This book is an outstanding example of green revolution providing a breathing space by putting the cereal grain production rate ahead of the population growth rate and then when food security has been adequately established, the system is changed to achieve productivity in perpetuity without causing environmental and social harm.

The authors define sustainable agriculture as "the umbrella term for approaches to agriculture that are environmentally friendly, profitable, and fair to farmers and ranchers." One of Horne's positive solutions to agribusiness-as-usual is to pay farmers to implement sustainable practice, rather than pay them later to clean up pollution or compensate for overproduction. Horne's eight goals of sustainability are healthy soil, increasing water conservation and quality, managing organic waste without pollution, safer pest management, adopting livestock and crops more adapted to nature, increased biodiversity, energy conservation, increased profitability, and reduced risk. Horne hopes to convert farmers to sustainable agriculture with folksy lines like: "I feel like I'm carrying on in the pioneer spirit of Oklahoma-- breaking new ground, looking for a better life. What keeps me going is the knowledge that the good earth will sustain us if we treat her right." Horne is president of the Kerr Center for Sustainable Agriculture in Oklahoma.

After 20 years, the "green revolution" is generally referred to as a milestone in the international agricultural movement. The introduction of new varieties of wheat and rice, along with fertilizers, pesticides, and mechanized farm equipment has produced a dramatic increase in world food production. This paper assesses the successes of the green revolution in light of its effect upon third world countries. It cautions that the revolutionary gains in agricultural production have not been distributed evenly. This uneven distribution of productivity is discussed in the first chapter, "Productivity Reconsidered." The second chapter, "Beyond the Green Revolution," considers the need for new crop varieties and technologies (including biotechnologies) but argues that tomorrow's innovations must be more consistent with regional agricultural traditions. This approach will help to avoid some of the environmental and social costs associated with the agricultural technologies utilized during the green revolution. The third chapter, "Rediscovering Traditional Agriculture," examines the benefits and limitations of traditional methods of agriculture, indicating that these practices should provide the basis for new practices, rather than be swept aside as archaic. "Toward Appropriate Biotechnology" discusses some of the possible contributions offered by biotechnology as tools for more efficient and sustainable agriculture. The document concludes with a call for additional research in sustainable agriculture productivity. (TW)

A single seed is more than just the promise of a plant. In rural south India, seeds represent diverging paths toward a sustainable livelihood. Development programs and global agribusiness promote genetically modified seeds and organic certification as a path toward more sustainable cotton production, but these solutions mask a complex web of economic, social, political, and ecological issues that may have consequences as dire as death. In Cultivating Knowledge anthropologist Andrew Flachs shows how rural farmers come to plant genetically modified or certified organic cotton, sometimes during moments of agrarian crisis. Interweaving ethnographic detail, discussions of ecological knowledge, and deep history, Flachs uncovers the unintended consequences of new technologies, which offer great benefits to some—but at others’ expense. Flachs shows that farmers do not make simple cost-benefit analyses when evaluating new technologies and options. Their evaluation of development is a complex and shifting calculation of social meaning, performance, economics, and personal aspiration. Only by understanding this complicated nexus can we begin to understand sustainable agriculture. By comparing the experiences of farmers engaged with these mutually exclusive visions for the future of agriculture, Cultivating Knowledge investigates the human responses to global agrarian change. It illuminates the local impact of global changes: the slow, persistent dangers of pesticides, inequalities in rural life, the aspirations of people who grow fibers sent around the world, the place of ecological knowledge in modern agriculture, and even the complex threat of suicide. It all begins with a seed.

This volume explores the usefulness of the Asian model of agricultural development for Africa, where, even before the recent world food crisis, half the population lived on less than on dollar a day, and a staggering one in three people and one third of all children were undernourished. Africa has abundant natural resources; agriculture provides most of its jobs, a third of national income and a larger portion of total export earnings. However the levels of land and labor productivity rank among the worst in the world. The book explains Africa’s productivity gap and proposes ways to close it, by examining recent experience in Africa and by drawing on lessons from Asia.

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.

This book investigates the effect of the Green Revolution (GR) on long-term changes in the fertility status of paddy soils in tropical Asia. While information on long-term changes in soil fertility status are rather limited due to difficulties in obtaining past data or samples for comparison, this investigation on temporal changes in soil fertility is possible by comparing fertility status in the 2010s, which the authors examined recently, with those from the 1960s, when GR was initiated, which was reported by Kawaguchi & Kyuma (1977). More than 220 paddy soils collected from Thailand, the Philippines, Malaysia, Bangladesh, and Indonesia were analyzed for their physicochemical properties as well as total and available fractions of plant macro- and micro- essential elements, and their temporal changes were examined in addition to their spatial variation in each country. The most significant change was a drastic increase of available phosphorus in soils, possibly due to fertilization after the GR. Changes in organic matter, pH, and other nutrients were relatively small. A considerable decrease in the content of some micronutrients was also observed. Long-term studies on soil fertility status in the past and present will be useful to establish soil/fertilizer management for sustainable rice production in the future. This book is an essential reading for soil scientists, agricultural scientists, environmental scientists, as well as policymakers and nongovernmental officers such as FAO.
