Urban-System Evolution on the Frontier of the Ecuadorian Amazon
Like the North American frontier, Ecuador's Amazonian margin has advanced in periodic waves. But the impetus has been extremely varied, interlacing periods of socioeconomic crisis with times of prosperity. Recent events in eastern Ecuador confirm that urbanization is a fundamental component of frontier development in South America. The urbanization process is not a sign, however, of regional economic strength. Capital gains at the periphery are t…
Farmer Perception of Soils in the Mountains of the Dominican Republic
Scientists concerned with resource management in developing nations have been surprisingly reluctant to seek opinions of traditional farmers despite growing recognition of their skills (Barlett, 1980; Altieri, 1983; Conant et al., 1983). Farmer classifications of climate, soil and vegetation can be very informative (Wilken, 1989). The purpose of this paper is to examine farmer perception of soils in Las Cuevas, a mountainous region in the Central…
Land Evaluation for Steepland Agriculture in the Dominican Republic
Inhabitants of rural areas represent an invaluable but neglected source of information for scientists concerned with land evaluation in the tropics. In this study, site suitability ratings were scientifically developed for six uses: coffee; beans; grazing; pigeon peas; garlic and rice. These ratings were compared to farmers' opinions of site suitability. The study area was Las Cuevas watershed, a tropical steepland region in the Dominican Republi…
