Book Description
This paper examines closely the constraints in productivity improvements and evaluates available rice technologies looking at the heterogeneity of irrigated and rainfed ecologies in 10 regions in Ghana. Employing yield response models, profitability analysis, and adoption models, results show various practices contribute to yield improvements in irrigated and rainfed systems including chemical fertilizer use, use of certified seed of improved varieties, transplanting, bunding, leveling, use of a sawah system, seed priming, and row planting. Evidence also shows that extension services on rice production are limited and that intensifying extension services can contribute to increases in rice yield.

Book Description
Scenes of starvation have drawn the world's attention to Africa's agricultural and environmental crisis. Some observers question whether this continent can ever hope to feed its growing population. Yet there is an overlooked food resource in sub-Saharan Africa that has vast potential: native food plants. When experts were asked to nominate African food plants for inclusion in a new book, a list of 30 species grew quickly to hundreds. All in all, Africa has more than 2,000 native grains and fruitsâ€""lost" species due for rediscovery and exploitation. This volume focuses on native cereals, including: African rice, reserved until recently as a luxury food for religious rituals. Finger millet, neglected internationally although it is a staple for millions. Fonio (acha), probably the oldest African cereal and sometimes called "hungry rice." Pearl millet, a widely used grain that still holds great untapped potential. Sorghum, with prospects for making the twenty-first century the "century of sorghum." Tef, in many ways ideal but only now enjoying budding commercial production. Other cultivated and wild grains. This readable and engaging book dispels myths, often based on Western bias, about the nutritional value, flavor, and yield of these African grains. Designed as a tool for economic development, the volume is organized with increasing levels of detail to meet the needs of both lay and professional readers. The authors present the available information on where and how each grain is grown, harvested, and processed, and they list its benefits and limitations as a food source. The authors describe "next steps" for increasing the use of each grain, outline research needs, and address issues in building commercial production. Sidebars cover such interesting points as the potential use of gene mapping and other "high-tech" agricultural techniques on these grains. This fact-filled volume will be of great interest to agricultural experts, entrepreneurs, researchers, and individuals concerned about restoring food production, environmental health, and economic opportunity in sub-Saharan Africa.

Book Description
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.

Book Description
Improved food security, led by increased productivity among Africa's many small-scale farmers, has been the aim of significant national and international effort in recent decades. It has proved to be one of the most critical challenges facing humankind. This book grew out of a two-year exploration conducted by the food security theme of The Rockefeller Foundation focusing on the potential for crop genetic improvement to contribute to food security among rural populations in Africa. It provides a critical assessment of the ways in which recent breakthroughs in biotechnology, participatory plant breeding, and seed systems can be broadly employed in developing and delivering more productive crop varieties in Africa's diverse agricultural environments. It also presents an analysis of current plant breeding and biotechnology strategies for the key crops in Africa including: maize, sorghum, cowpea, rice, and cassava. The book will appeal to plant breeders, biotechnologists, and seed distributors as well as policy-makers in the area of agricultural development.

Book Description
The recent escalation of world food prices – particularly for cereals - prompted mass public indignation and demonstrations in many countries, from the price of tortilla flour in Mexico to that of rice in the Philippines and pasta in Italy. The crisis has important implications for future government trade and food security policies, as countries re-evaluate their reliance on potentially more volatile world markets to augment domestic supplies of staple foods. This book examines how government policies caused and responded to soaring world prices in the particular case of rice, which is the world's most important source of calories for the poor. Comparable case studies of policy reactions in different countries, principally across Asia, but also including the USA, provide the understanding necessary to evaluate the impact of trade policy on the food security of poor farmers and consumers. They also provide important insights into the concerns of developing countries that are relevant for future international trade negotiations in key agricultural commodities. As a result, more appropriate policies can be put in place to ensure more stable food supplies in the future. Published with the Food and Agriculture (FAO) Organization of the United Nations

Book Description
The rice belt of Laguna Province, Philippines (popularly known as the heartland of the Green Revolution for its early adoption of modern rice varieties), has experienced dramatic economic and social changes in the last quarter of the twentieth century. Besides the major advances in new rice technology, four major forces have prompted change: increasing population pressure on limited land; implementation of land reform programs; developments in infrastructure such as irrigation and roads; and penetration of urban economic activities. A unique data set generated from many surveys during the period 1966-97 in a typical village in Laguna, as put together in this book, illustrates a pattern of socio-economic change shared by many irrigated rice areas in the Philippines as well as in other Asian economies.

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 critical text is a timely ethnography of how global powers, local resistance, and capital flows are shaping contemporary African foodways. Ghana was one of the first countries targeted by a group of US donors and agribusiness corporations that funded an ambitious plan to develop genetically modified (GM) crops for African farmers. The collective believed that GM crops would help farmers increase their yields and help spark a “new” Green Revolution on the continent. Soon after the project began in Ghana, a nationwide food sovereignty movement emerged in opposition to GM crops. Today, in spite of impressive efforts and investments by proponents, only two GM crops remain in the pipeline. Why, after years of preparation, millions of dollars of funding, and multiple policy reforms, did these megaprojects effectively come to a halt? One of the first ethnographies to take on the question of GM crops in the African context, We Are Not Starving: The Struggle for Food Sovereignty in Ghana blends archival analysis, interviews, and participant observation with Ghanaian scientists, farmers, activists, and officials. Ultimately the text aims to illuminate why GM crops have animated the country and to highlight how their introduction has opened an opportunity to air grievances about the systematic de-valuing and exploitation of African land, labor, and knowledge that have been centuries in the making.
