Book Description
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.

Book Description
Soil acidity is a major limitation to crop production in many parts of the world. Plant growth inhibition results from a combination of factors, including aluminum, manganese, and hydrogen ion toxicities and deficiencies of essential elements, particularly calcium, magnesium, phosphorus, and molybdenum. Agricultural management practices and acid precipitation have increased acid inputs into the ecosystem and heightened concern about soil acidity problems. While application of lime has proved to be effective in ameliorating surface soil acidity in many areas, significant soil acidity problems still exist. Scientists from Alberta, Canada, recognized the need to provide a forum for researchers from different disciplines to exchange information and ideas on solving problems of plant growth in acid soils. As a result of their efforts, the First International Symposium on Plant-Soil Interactions at Low pH was held at Grande Prairie, Alberta, Canada, in July 1987. In many acid soil areas, liming materials are not readily available, the cost may be prohibitive, or subsoil acidity cannot be corrected by surface application of lime. New management approaches involving both the plant and the soil are needed in these situations. Progress has been made in the selection and breeding of acid-tolerant plants. However, continued progress will be limited by our lack of understanding of the physiological and biochemical basis of differential acidity tolerance among plants.

Book Description
The history, science, and social aspects of today’s Thai agriculture is traced from hunters and gatherers through agro-cities through State-religious Empires and immigrating Tai to produce a sustainable agriculture. The wet glutinous rice culture determined administrative structures in a pragmatic society which regularly produced a saleable surplus. Continuing today, these systems consolidated the importance of rice agriculture to national security and economic well-being, as Chinese and European influence benefited agribusiness and initiated the demand which would expand agriculture through population increase until accessible land was expended. As agriculture declined in relative financial importance, it continued to provide the benefits of employment, crisis resilience, self-sufficiency, rural social support, and cultural custody. Agricultural institutions evolved from a taxation and dispute resolution base to provide research, education, and technology transfer at levels below potential as they supported commercial agriculture funded by credit. Agribusiness expanded from the 1960s and small-holders were partly viewed as a past relic which agribusiness could modernise. Unique elements of Thai agriculture include: irrigation technologies; administrative structures based on water control; global leadership in many agricultural commodities; multinational agribusiness; negotiating approaches; potential for further increases from known technologies, and an open culture which has embraced new ideas. One of the world’s few major agricultural exporters, Thailand leads the world in rice, rubber, canned pineapple, and black tiger prawn production and export, the region in chicken meat export and several other commodities, and feeds more the four times its own population from less intensive agriculture than its neighbours. Poised to benefit from expansion in livestock demand, poverty reduction, and improved education, research, and legal and social systems, evident in the recent Asian financial crisis, will be considered with popular concern for socially sensitive alternatives for small-holder farmers to co-exist with commercial agriculture. Thailand will likely remain one of the world’s major agricultural countries in social, environmental and economic terms for the foreseeable future, as it addresses the continuing rural issues of poverty and inequity.
