DOWNLOAD EBOOKIn tropical developing countries farmers tend to grow a wide range of crops in a small area for subsistence or sale. To make full use of often limited resources, a good understanding of how environmental conditions affect the characteristics and performance of these crops is essential. This book considers the response of tropical food crops to environmental factors such as climate, soil and farming system. Three types of crop are considered: cereals, legumes and non-cereal energy crops, with individual chapters on the four most important crops in each group. This material is set in context by introductory chapters on tropical farming systems, tropical climates and tropical soils. This new, updated edition retains the successful formula of the first edition while placing additional emphasis on tropical environmental conservation. It will serve the needs of advanced students of tropical agriculture, as well as professionals engaged in research and extension work in tropical crop production.

DOWNLOAD EBOOKThe tropics are the source of many of our familiar fruits, vegetables, oils, and spice, as well as such commodities as rubber and wood. Moreover, other tropical fruits and vegetables are being introduced into our markets to offer variety to our diet. Now, as tropical forests are increasingly threatened, we face a double-fold crisis: not only the loss of the plants but also rich pools of potentially useful genes. Wild populations of crop plants harbor genes that can improve the productivity and disease resistance of cultivated crops, many of which are vital to developing economies and to global commerce. Eight chapters of this book are devoted to a variety of tropical crops—beverages, fruit, starch, oil, resins, fuelwood, fodder, spices, timber, and nuts—the history of their domestication, their uses today, and the known extent of their gene pools, both domesticated and wild. Drawing on broad research, the authors also consider conservation strategies such as parks and reserves, corporate holdings, gene banks and tissue culture collections, and debt-for-nature swaps. They stress the need for a sensitive balance between conservation and the economic well-being of local populations. If economic growth is part of the conservation effort, local populations and governments will be more strongly motivated to save their natural resources. Distinctly practical and soundly informative, this book provides insight into the overwhelming abundance of tropical forests, an unsettling sense of what we may lose if they are destroyed, and a deep appreciation for the delicate relationships between tropical forest plants and people around the world.

DOWNLOAD EBOOKThe mission of the International Fertilizer Development Center is to increase food production through the improvement of fertilizers and fertilizer practices for the developing countries with special emphasis on tropical and subtropical agriculture. The principal aim is to ensure that fertilizer technology is not a limiting factor to food production in those regions. Although the full extent to which deficiency of micronutrients hampers food production is yet un known, there is ample evidence that problem areas exist and more will be identified as crop production is intensified and marginal lands are exploited. Therefore, it seems fully appropriate at this time that IFDC, as an international organization, take a leadership role in developing micronutrient fertilizer technology appropriate for the tropics and subtropics. The gravity of micronutrient deficiency as a limiting factor to crop pro duction varies from crop to crop and from soil to soil. The effects may range from slight yield reductions to complete crop failure. While the economic impact of omitting micronutrients in seriously affected areas (e.g., Zn in Brazilian Cerrado) is convincing, it is difficult to estimate the yearly loss in crop production due to unsuspected micronutrient deficiency. Active soil and crop testing programs in regions with advanced agricultural systems are aimed at recognizing micronutrients as a limiting plant nutrient in time to allow corrective measures and prevent yield loss. Successful micronutrient monitoring systems are generally limited to developed economies or to developing economies producing export cash crops.

DOWNLOAD EBOOKTropical East Asia is home to over one billion people and faces massive human impacts from its rising population and rapid economic growth. It has already lost more than half of its forest cover to agriculture and urbanization, and has the highest rates of deforestation and logging in the tropics. Habitat loss, coupled with hunting and the relentless trade in wildlife products, threatens all its large and many of its smaller vertebrates. Despite these problems, the region still supports an estimated 15-25% of global terrestrial biodiversity and a growing environmental awareness means that it is no longer assumed that economic development justifies environmental damage, and no longer accepted that this trade-off is inevitable. Effective conservation action now depends on integrating a clear understanding of the ecological patterns and processes in the region with the varied needs of its human population. This third edition continues to provide an overview of the terrestrial ecology of Tropical East Asia: from southern China to Indonesia, and from Bhutan and Bangladesh to the Ryukyu Islands of Japan. It retains the balance between compactness and comprehensiveness of the previous editions, and the even-handed geographical treatment of the whole region, but it updates both the contents and the perspective. Approximately one third of the text is new or greatly modified, reflecting the explosion of new research in the region in the last few years and the increasing use of new tools, particularly from genomics and remote sensing. The change in perspective largely reflects the growing realization that we are in a new epoch, the Anthropocene, in which human activities have at least as large an influence as natural processes, and that stopping or reversing ecological change is no longer an option. This does not mean that biodiversity conservation is no longer possible or worthwhile, but that the biodiverse future we strive for will inevitably be very different from the past. The Ecology of Tropical East Asia is an advanced textbook suitable for senior undergraduate and graduate level students taking courses on the terrestrial ecology of the East Asian tropics, as well as an authoritative regional reference for professional ecologists, conservationists, and interested amateurs worldwide.

DOWNLOAD EBOOKTropical Radioecology is a guide to the wide range of scientific practices and principles of this multidisciplinary field. It brings together past and present studies in the tropical and subtropical areas of the planet, highlighting the unique aspects of tropical systems. Until recently, radioecological models for tropical environments have depended upon data derived from temperate environments, despite the differences of these regions in terms of biota and abiotic conditions. Since radioactivity can be used to trace environmental processes in humans and other biota, this book offers examples of studies in which radiotracers have been used to assess biokinetics in tropical biota. This book: Features chapters co-authored by world experts that explain the origins, inputs, distributions, behaviour, and consequences of radioactivity in tropical and subtropical systems. Provides comprehensive lists of relevant data and identifies current knowledge gaps to allow for targeted radioecological research in the future. Integrates radioecological information into the most recent radiological consequences modelling and best-practice probabilistic ecological risk analysis methodology, given the need to understand the implications of enhanced socio-economic development in the world's tropical regions. John Twining has published research and conducted field and laboratory studies on the nuclear industry's impact on the environment over four decades. While much of this work has been related to Australia's role as a uranium supplier, he has also evaluated this impact at the Maralinga test sites in the deserts of central Australia and the effects of French testing in the central Pacific. John also focused on the uptake of radionuclides by crops and the use of isotopes as tracers of biological processes. Much of this work was accomplished in tropical or subtropical environments, and this experience proved valuable for Tropical Radioecology. John is now associate editor for the Journal of Environmental Radioecology and a self-employed consultant radioecologist.
