Book Description
In 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.

Book Description
Tropical 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.

Book Description
The 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.

Book Description
This study shows how classical ecological principles, especially those relating to competition and population ecology, can be applied to growing two or more crops together and how the approach can improve agricultural yields.

Book Description
Feeding the world's growing human population is increasingly challenging, especially as more people adopt a western diet and lifestyle. Doing so without causing damage to nature poses an even greater challenge. This book argues that in order to create a sustainable food supply whilst conserving nature, agriculture and nature must be reconnected and approached together. The authors demonstrate that while the links between nature and food production have, to some extent, already been recognized, until now the focus has been to protect one from the impacts of the other. Instead, it is argued that nature and agriculture can, and should, work together and ultimately benefit from one another. Chapters describe efforts to protect nature through globally connected protected area systems and illustrate how farming methods are being shaped to protect nature within agricultural systems. The authors also point to many ways in which nature benefits agriculture through the ecosystem services it provides. Overall, the book shows that nature conservation and food production must be considered as equally important components of future solutions to meet the global demand for food in a manner that is sustainable for both the human population and the planet as a whole.

Book Description
This book looks at the input-output relations of low-resource agriculture in Africa and shows how the intensification process through the application of modern technologies can work successfully to raise productivity and to sustain production over the long term.
