Agricultural droughts affect whole societies, leading to higher food costs, threatened economies, and even famine. In order to mitigate such effects, researchers must first be able to monitor them, and then predict them; however no book currently focuses on accurate monitoring or prediction of these devastating kinds of droughts. To fill this void, the editors of Monitoring and Predicting Agricultural Drought have assembled a team of expert contributors from all continents to make a global study, describing biometeorological models and monitoring methods for agricultural droughts. These models and methods note the relationships between precipitation, soil moisture, and crop yields, using data gathered from conventional and remote sensing techniques. The coverage of the book includes probabilistic models and techniques used in America, Europe and the former USSR, Africa, Asia, and Australia, and it concludes with coverage of climate change and resultant shifts in agricultural productivity, drought early warning systems, and famine mitigation. This will be an essential collection for those who must advise governments or international organizations on the current scope, likelihood, and impact of agricultural droughts.

Managing climate variability and change remains a key development and food security issue in Bangladesh. Despite significant investments, floods, droughts, and cyclones during the last two decades continue to cause extensive economic damage and impair livelihoods. Climate change will pose additional risks to ongoing efforts to reduce poverty. This book examines the implications of climate change on food security in Bangladesh and identifies adaptation measures in the agriculture sector using a comprehensive integrated framework. First, the most recent science available is used to characterize current climate and hydrology and its potential changes. Second, country-specific survey and biophysical data is used to derive more realistic and accurate agricultural impact functions and simulations. A range of climate risks (i.e. warmer temperatures, higher carbon dioxide concentrations, changing characteristics of floods, droughts and potential sea level rise) is considered to gain a more complete picture of potential agriculture impacts. Third, while estimating changes in production is important, economic responses may to some degree buffer against the physical losses predicted, and an assessment is made of these. Food security is dependent not only on production, but also future food requirements, income levels and commodity prices. Finally, adaptation possibilities are identified for the sector. This book is the first to combine these multiple disciplines and analytical procedures to comprehensively address these impacts. The framework will serve as a useful guide to design policy intervention strategies and investments in adaptation measures.

This information proves valuable to researchers if further work is needed for improvement on these plant-derived products.

The Mango is one of the oldest cultivated fruit crops, having been grown in India for at least 4000 years. Mango is the most important fruit crop of Asia and its annual production is exceeded worldwide only by Musa, citrus, grapes and apples. The last decade has seen a rapid growth of mango production, mainly due to expansion into new growing regions but also to the adoption of modern field practices and cultivars. A wide range of fresh, mango cultivars are now consumed worldwide and are available year round. "The Mango: Botany, Production and Uses," published in 1997, represented the first comprehensive examination of all aspects of modern mango production and research. Developing upon the successful first edition, this book incorporates a discussion of significant advances in mango research that have contributed to improved production and will be highly relevant for researchers and growers alike.

In large parts of the developed and developing worlds soil tillage by plough or hoe is the main cause of land degradation leading to stagnating or even declining production levels and increasing production cost. It causes the soil to become more dense and compacted, the organic matter content to be reduced and water runoff and soil erosion to increase. It also leads to droughts becoming more severe and the soil becoming less fertile and less responsive to fertiliser.

This book brings together the key notes lectures and other outstanding contributions of the I World Congress on Conservation Agriculture and provides an updated view of the environment and economic advantages of CA and of its implementation in diferent areas of the World.

Dioscorea species, commonly known as yams, are tuberous plants that constitute a major staple food in many parts of Africa, South East Asia, Latin America and the South Pacific. Yams are cultivated in about 50 mainly tropical countries, and the world annual production of edible tubers is around 73 million tonnes. This book evaluates the current state of knowledge about yams, and how this knowledge affects practices in production, cultivation and postharvest technology. Dioscorea is a diverse genus in terms of its geographical origin, domestication, morphology, chemistry and breeding. Therefore, besides concentrating on the dozen or so species that are used as major food crops, the book examines species that have limited commercial or domestic value at present, but have the potential in future to contribute to the production and utilization of this crop. This book: * Covers botany, taxonomy, composition, uses, cultivation, handling, storage, diseases, pests and production. * Describes the yam industry in the main producer countries, and around 100 of the most commonly grown species. * Reviews many Dioscorea species that may be developed in the future. It is an essential resource for researchers in horticulture, yam growers, breeders and postharvest technologists.

Enormous changes are affecting African production agriculture, urbanization, and food consumption patterns, requiring new approaches to training and knowledge generation and dissemination to achieve food security. Many agricultural universities and other tertiary agricultural education (TAE) organizations have been slow to respond, hindered by inadequate staffing and facilities and growing competition for funds. However, some African agricultural universities are transforming themselves and are achieving remarkable success. This book documents successful approaches to remaking TAE in Africa to inspire leaders, both formal and informal, of other TAE organizations. It emphasises adaptive strategies and processes creating an internal culture driven by stakeholder needs and where organizational transformation improves the quality and relevance of teaching, research, and outreach. The chapters cover the role of TAE in agricultural transformation, trends in TAE in Africa, solutions to the rigour-versus-relevance dilemma, curriculum design informed by actual and emerging labour market conditions, innovation and entrepreneurship, TAE quality assurance, and networking among TAE institutions. This book: Emphasizes best practices within Africa rather than theories or models from outside Promotes adaptive organizational learning strategies rather than blueprints Promotes collaboration and networking for cross-learning and leveraging of resources Features practical examples and case studies This book is aimed at academics in Africa and abroad, students of agricultural development, educational and agricultural policy makers in Africa, international development partners, and education sector investors.

In many tropical areas, the main constraint to increased output of livestock products is the inability of producers to feed animals adequately throughout the year. Yet opportunities exist to enhance ruminant livestock feed supplies by using crop residues, such as cereal straw and legume haulms. Greater emphasis is therefore now being placed on vegetative production in plant breeding research. Crop residues also play an important role in conserving soil moisture, preventing erosion and providing products such as fuel or thatch for smallholders. This book provides a multi-disciplinary perspective on crop residues, bringing together crop, animal and social scientists from six continents. It has been developed from papers presented at a workshop held in April 1996, at ICRISAT Asia Center, as part of the Systemwide Livestock Program of the Consultative Group on International Agricultural Research (CGIAR) convened by the International Livestock Research Institute (ILRI), based in Africa. It will appeal to a wide readership in disciplines as diverse as agronomy, soil science, plant breeding, animal nutrition and socio-economics.

Papaya (Carica papaya) is an important and widely-cultivated tropical fruit, grown in more than 60 countries of the world. Global papaya production has grown significantly over the last few years, mainly as a result of increased production in India. Papaya has become an important agricultural export for developing countries where export revenues of the fruit provide a livelihood for thousands of people, especially in Asia and Latin America. This book includes coverage of recent research developments with the potential to improve crop yields and quality. New research has contributed to our understanding of the crop environment, plant growth and physiology of tree and fruit development with implications for both breeding and cultivation. It looks at how analysis of the papaya genome promises new, faster breeding techniques to improved cultivars and how these and other advances are helping to tackle disease like papaya ring spot viruses and major pests which cause significant losses. Key features include: updated information for sustainable papaya cultivation research developments in tackling the major production and post-harvest problems interdisciplinary and collaborative research With contributions from international experts, the book presents the current state of knowledge concerning the history, physiology, culture and marketing of papaya throughout the world. It is an essential resource for researchers, growers and all those involved in the papaya industry.

The contributions to this collection focus on the intersecting dynamics of gender, generation and class in Southeast Asian rural communities engaging with expanding capitalist relations, whether in the form of large-scale corporate land acquisition or other forms of penetration of commodity economy. Gender, and especially generation, are relatively neglected dimensions in the literature on agrarian and environmental transformations in Southeast Asia. Drawing on key concepts in gender studies, youth studies and agrarian studies, the chapters mark a significant step towards a gendered and 'generationed' analysis of capitalist expansion in rural Southeast Asia, in particular from a political ecology perspective. The collection highlights the importance of bringing gender and generation, in their interaction with class dynamics, more squarely into agrarian and environmental transformation studies. This is key to understanding the implications of capitalist expansion for social relations of power and justice, and the potential of these relations to shape the outcomes for different women and men, younger and older, in rural society. The chapters in this book were originally published in a special issue of The Journal of Peasant Studies.

Oil palm is widely cultivated in tropical countries for use in food processing, personal care products and other applications such as biodiesel. Cultivation faces a range of challenges such as its environmental impact (e.g. in deforestation and biodiversity loss) as well threats from pests and diseases. There is an urgent need to make oil palm cultivation more efficient and environmentally sustainable. This collection reviews the key research addressing this challenge. Volume 1 begins by reviewing trends in production and key challenges facing the sector. Part 2 focusses on developments in understanding oil palm physiology, genetics and genetic diversity and their application to improved breeding techniques. The final part of the book discusses developments in cultivation practices. With its distinguished editor and international team of expert authors, this collection will be a standard reference for researchers, oil palm growers, palm oil processors as well as government and non-governmental agencies responsible for more sustainable oil palm cultivation. Volume 1 is accompanied by Volume 2 which covers pests and diseases, quality and sustainability issues

As populations continue to grow in tropical countries, there is an ever increasing pressure to produce more food from less land, while at the same time maintaining the quality of the environment. This textbook integrates research in agronomy, physiology, environmental physics and soil science to provide a framework for analyzing practical problems associated with crop production in tropical environments. The impact of essential resources, such as solar radiation and water, are discussed and research findings are used to illustrate solutions to real challenges. The book will serve as a core textbook for advanced undergraduate courses in agronomy.

Sustainable crop production is vital to ensure that supplies of fresh vegetables and their products are readily available. However, food security still remains a huge problem in areas of the world, including the tropics and sub-tropics, where communities rely solely on subsistence farming to meet their day-to-day food demands. It is evident that food production needs to become more sustainable to ensure economic stability and poverty reduction. With this in mind, "Tropical Vegetable Production" addresses the problems surrounding vegetable production in developing countries. Divided into two parts, this volume discusses first the principles and practice of tropical vegetable production, from site selection, security and management to seeds, crop preparation and pesticides, and second, provides details of those crops which are of particular importance in developing countries.

Rich countries are paying poor countries to fight climate change on their behalf - and one way they are doing it is through carbon sinks. These are reservoirs of organic carbon tied up in plants and in the earth, rather than being in the atmosphere as greenhouse gases. This book looks critically at this mode of climate change mitigation. Can it work? Is it just? Will poorer countries benefit? The book considers the scientific, economic and ethical basis for this type of mitigation.

Previous attention has been focused mainly on reducing emissions from deforestation and land degradation (REDD), but this book is one of the first attempts to examine the potential for carbon sinks in agriculture in crop plants and the soil. In assessing this, the author examines exactly how north-south climate mitigation trading works, or does not, and what the pitfalls are. It highlights the complex relationship between agriculture, particularly different forms of farming systems, and the mitigation of climate change. The arguments are backed up by original research with farmers in Brazil to demonstrate the challenges and prospects which these proposals offer in terms of payments for environmental services from agriculture through carbon trading.

The literature of Africa is dominated by accounts of crisis and gloom. But Thomas Bassett, a distinguished American geographer well known in the field of development, tells an unusual story of the growth of the cotton economy of West Africa. One of the few long-running success stories in African development, change was brought about by tens of thousands of small-scale peasant farmers. While the introduction of new strains of cotton in French West Africa was in part a result of agronomic research by French scientists, supported by an unusually efficient marketing structure, this is not a case of triumphant top-down 'planification'. Employing the case of Cote d'Ivoire, Professor Bassett shows agricultural intensification to result from the cumulative effect of decades of incremental changes in farming techniques and social organization. A significant contribution to the literature, the book demonstrates the need to consider the local and temporal dimensions of agricultural innovations. It brings into question many key assumptions that have influenced development policies during the twentieth century.

This introduction to tropical food science is meant for two groups of people. First, there are those living in the tropics who require a simple introductory text. Food science is perhaps the most important science affecting their lives. The second group consists of students, administrators and workers in industry and research in temperate zones, who are concerned with food problems but who have no first-hand knowledge of the tropics. The text provides a concise and accessible guide to all the major elements of the subject, including the nutritional value of tropical foodstuffs, its digestion, and the preparation and preservation of food. The author has taken care to avoid the use of jargon and the text is supplemented by many useful explanatory illustrations. The volume is suitable for first-year food science students at universities, polytechnics and colleges; graduate students taking conversion courses in food science; administrators, practitioners and students of food science in the tropics.

The manual reflects the working practices of BAI and concentrates on those aspects of development studies handled by soil scientists as members of multi-disciplinary teams.

Diseases caused by Ganoderma species cause major losses of palms and other perennial crops throughout the world, and these are particularly significant in Asia. Successive replanting of crop monocultures can be rapidly exploited by soil-borne fungi such as Ganoderma, and the problem will become more serious in the 21st century, as more areas become due for second or even third replanting. Environmental considerations will reduce exploitation of new forest areas, making further replanting of these crops inevitable. Thus, appropriate, integrated management systems for these diseases are vital. However, the development of such control measures has been hampered in the past by a limited knowledge of the nature and inter-relationships of populations of different hosts and the mechanisms of disease establishment and spread.This book aims to address these limitations through enhanced knowledge of the biology and taxonomy of Ganoderma species. The use of molecular and biochemical methods can be used to provide a greater understanding of the spread of the pathogen, and consequently, the improved management of disease.

Biological control has been central to many recent successful integrated pest management programmes. It is also the natural choice where protection of the environment is particularly important. This book reviews current knowledge of biocontrol programmes in the tropics, particularly in developing countries. It is based on papers presented at a symposium held in Malaysia in March 1999. Contributors include authorities from Europe, North America and Australia, as well as from South-East Asia.
