Available in PDF, EPUB and Kindle. Book excerpt: Most basic information on plant-mealybug interactions during the last decade has come from research on the cassava Manihot esculenta Crantz (Euphorbiaceae) system with two mealybug species, namely Phenacoccus manihoti Matile-Ferrero and Phenacoccus herreni Cox and Williams (Sternorrhyncha: Pseudococcidae). Both these insects cause severe damage to cassava in Africa and South America, respectively. This book reviews these interactions (plant selection by the insects, nutritional requirements

Book Synopsis The Conservation Atlas of Tropical Forests by : International Union for Conservation of Nature and Natural Resources
Download or read book The Conservation Atlas of Tropical Forests written by International Union for Conservation of Nature and Natural Resources and published by Macmillan Reference USA. This book was released on 1992 with total page 300 pages. Available in PDF, EPUB and Kindle. Book excerpt: Africa's forests are being depleted at a faster rate than of any other continent. A major increase in the population growth rate began after World War II and it is now running at an annual rate of 2.9 per cent, resulting in massive demands for agricultural land, water, fuelwood and other products. There is no simple answer to environmental degradation and forest conservation must be part of a broader process of managing the landscape. Here to address this topic is the new Conservation Atlas of Tropical Forests: Africa, the first authoritative reference work on this subject. The second in a series this Conservation Atlas follows the format of the acclaimed Conservation Atlas of Tropical Forests: Asia and the Pacific (1991). Part I describes the issues, history of forests and climate, biological diversity, conservation of large mammals, and the peoples of the forests. Included are discussions of the links between population, environment and agriculture, the timber trade, protected areas system and the future for Africa's forests. Part II of the Atlas is a country by country survey of the forests of Africa. Stunning four-color maps, in a 9 x 12 format, have been compiled from satellite and radar imagery, aerial photography, and the latest information provided by forestry departments and development agencies. Both maps and text have been prepared and reviewed by a broad spectrum of specialists. The Atlas also includes four-color photographs and sketch maps. They represent the best visual portfolio available of Africa's forests today. For anyone interested in environmental issues, geography, forestry, development, economics, and the African region, this Atlas will be an essential resource.

Book Synopsis Gambling with the Land by : Rodolphe de Koninck
Download or read book Gambling with the Land written by Rodolphe de Koninck and published by NUS Press. This book was released on 2012 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Gambling with the Land surveys and analyzes systematically the production and trade of all major agricultural crops throughout Southeast Asian between 1960 and the late 2000s. After reviewing the specific economic, social and political role of agriculture in the eight major agricultural countries - Burma, Thailand, Laos, Cambodia, Vietnam, Malaysia, Indonesia and the Philippines - since the end of the colonial period, the authors show how Southeast Asian agricultures have gradually satisfied local demand for food while catering increasingly to the world market for agricultural produce, predominantly through the export of industrial crops, with rice even remaining a major regional export. In terms of food security, the region has even been able to improve its position. All this has largely been achieved through massive intensification of cultivation and equally significant territorial expansion of the agricultural realm, a dynamic combination rarely achieved anywhere else in the world at such a scale. Expansion has even reached into the maritime domain, aquaculture growing even faster than agriculture per se. Both forms of expansion, on land as well as sea, are accentuating the pressure on environmental resources, particularly forests, including mangroves. It remains to be seen whether this gambling with the land and the sea can be sustained without jeopardizing regional food security. Not only are the stakes very high, but in nearly all countries agricultural policies, particularly those concerning agricultural frontiers and hence labour migration patterns, are increasingly defined by large scale private enterprises. Providing an insightful and critical overview of Southeast Asia's agricultural dynamism, Gambling with the Land is an indispensable reference book for all those interested in agricultural and environmental issues and an essential component of any library collection dealing with Asia.

Book Synopsis Ecological Impact Assessment by : Jo Treweek
Download or read book Ecological Impact Assessment written by Jo Treweek and published by Wiley-Blackwell. This book was released on 1999-03-17 with total page 368 pages. Available in PDF, EPUB and Kindle. Book excerpt: The world's ecosystems are increasingly threatened by human development. Ecological impact assessment (EcIA) is used to predict and evaluate the impacts of development on ecosystems and their components,thereby providing the information needed to ensure that ecological issues are given full and proper consideration in development planning. Environmental impact assessment (EIA) has emerged as a key to sustainable development by integrating social, economic and environmental issues in many countries. EcIA has a major part to play as a component of EIA but also has other potential applications in environmental planning and management. Ecological Impact Assessment provides a comprehensive review of the EcIA process and summarizes the ecological theories and tools that can be used to understand, explain and evaluate the ecological consequences of development proposals. It is intended for the many individuals and companies involved in EIA and EcIA, as well as other areas of environmental management where impacts on ecosystems need to be evaluated. It will benefit planners, regulators, environmental consultants and scientists and will also provide an invaluable sourcebook and guide for the growing number of undergraduate students taking courses in applied ecology, EIA and related topics in environmental science. A practical management guide for the increasing numbers of practitioners of EcIA. A rapidly expanding subject driven by the proliferation of environmental legislation worldwide.
Book Synopsis Statistical Methods in Agriculture and Experimental Biology by : Roger Mead

Available in PDF, EPUB and Kindle. Book excerpt: The third edition of this popular introductory text maintains the character that won worldwide respect for its predecessors but features a number of enhancements that broaden its scope, increase its utility, and bring the treatment thoroughly up to date. It provides complete coverage of the statistical ideas and methods essential to students in agriculture or experimental biology. In addition to covering fundamental methodology, this treatment also includes more advanced topics that the authors believe help develop an appreciation of the breadth of statistical methodology now available. The emphasis is not on mathematical detail, but on ensuring students understand why and when various methods should be used. New in the Third Edition: A chapter on the two simplest yet most important methods of multivariate analysis Increased emphasis on modern computer applications Discussions on a wider range of data types and the graphical display of data Analysis of mixed cropping experiments and on-farm experiments
