Book excerpt: A test program was conducted in Thailand in 1964 and 1965 to determine the effectiveness of aerial applications of Purple, Orange, and other candidate chemical agents in defoliation of upland jungle vegetation representative of Southeast Asia on duplicate 10-acre plots. Aerial spray treatments were applied at rates of 0.5 to 3.0 gallons per acre on two test sites representing tropical dry evergreen forest and secondary forest and shrub vegetation. Applications were repeated in alternate 2- to 3-month periods to determine minimal effective rates and proper season of application. Defoliation effectiveness was evaluated by (1) visual estimates of overall vegetation and individual species defoliation, (2) measurements of changes in canopy obscuration by a vertical photography technique, and (3) measurements of changes in horizontal visibility of a human-sized target at various ranges. Data provided by these techniques were used in comparative evaluation of defoliant chemicals in relation to rate, volume, season of application, canopy penetration, and vegetation response.

Download or read book Farmers in the Forest written by Peter R. Kunstadter and published by University of Hawaii Press. This book was released on 2019-03-31 with total page 599 pages. Available in PDF, EPUB and Kindle. Book excerpt: Farmers in the Forest, while using examples chiefly from northern Thailand, is concerned with complex problems found in all tropical countries. In these areas rapid population growth, increasing demands for food, and burgeoning international markets for forest products and other raw materials are associated with active competition for land and natural resources in upland areas. This book brings together studies by administrators, agronomists, anthropologists, forest ecologists, geographers and jurists, who describe a variety of swidden systems and their effect on soil, forest, society, and economy. They point to conflicts between traditional farming systems and modern legal and administrative constraints now being imposed, and they describe special and technological conditions that contribute to a marginal, stagnant upland economy, increasing socio-economic disparities with the lowlands, and the serious ecological consequences of these conditions. Several possible solutions are suggested to solve these problems.

Available in PDF, EPUB and Kindle. Book excerpt: This handbook of locally based agricultural practices brings together the best of science and farmer experimentation, vividly illustrating the enormous diversity of shifting cultivation systems as well as the power of human ingenuity. Environmentalists have tended to disparage shifting cultivation (sometimes called 'swidden cultivation' or 'slash-and-burn agriculture') as unsustainable due to its supposed role in deforestation and land degradation. However, a growing body of evidence indicates that such indigenous practices, as they have evolved over time, can be highly adaptive to land and ecology. In contrast, 'scientific' agricultural solutions imposed from outside can be far more damaging to the environment. Moreover, these external solutions often fail to recognize the extent to which an agricultural system supports a way of life along with a society's food needs. They do not recognize the degree to which the sustainability of a culture is intimately associated with the sustainability and continuity of its agricultural system. Unprecedented in ambition and scope, Voices from the Forest focuses on successful agricultural strategies of upland farmers. More than 100 scholars from 19 countries--including agricultural economists, ecologists, and anthropologists--collaborated in the analysis of different fallow management typologies, working in conjunction with hundreds of indigenous farmers of different cultures and a broad range of climates, crops, and soil conditions. By sharing this knowledge--and combining it with new scientific and technical advances--the authors hope to make indigenous practices and experience more widely accessible and better understood, not only by researchers and development practitioners, but by other communities of farmers around the world.
