“…However, an important thread of the literature questions whether ISFM/INRM practices that require minimal purchased external inputs are truly more accessible to poorer smallholders (Reardon and Vosti, 1997;Reardon et al, 2001;Barrett et al, 2002;Moser and Barrett, 2003). We explore this question not only by studying adoption patterns but also by looking at patterns of disadoption or abandonment of these four ISFM/INRM practices so as to establish whether household endowments affect both uptake and continuation of these practices.…”

“…Smallholder agriculture in much of the low-income tropics is nonetheless characterized by widespread failure to make sufficient soil fertility replenishment and soil conservation investments in order to sustain the quality of farmland (Sanchez et al, 2001;Reardon et al, 2001;Barrett et al, 2002;World Bank, 2003). A substantial literature based on cross-sectional analysis has explored the adoption of INRM and ISFM methods in order to understand the failure to make these critical investments (Sheikh et al, 2003;Phiri et al, 2003;Franzel et al, 2001;Pfister et al, 2005).…”

“…through infrastructure development, often increase the intensity of agricultural input use and the productivity of agriculture and reduces the risk associated with investments in agricultural production (Lee et al, 2001). In that way, better access to market can reduce the need for land expansion (Reardon et al, 2001). If roads open up formerly inaccessible areas, colonization pressures can result in environmental degradation (Lee et al, 2001).…”

This dissertation investigates the role of geophysical, agroecological, and socioeconomic determinants of land-use change during the last 25 years in two districts of Dak Lak province in the Central Highlands of Vietnam. The analysis of these determinants allows to assess the influences of various rural development policies on land-cover changes. Landsat satellite images from the same cropping period of the years 1975, 1992 and 2000 are interpreted to detect land-cover change between the two time periods. A survey in randomly selected villages provides primary recall data on socioeconomic and policy variables hypothesized to influence land-use change. Secondary data on rainfall, soil suitability, and topography were obtained from meteorological stations, from a digital soil map and a digital elevation model. All data were spatially referenced using GIS software. Survey data is merged with spatially explicit raster data using accessibility catchments, which are designed to approximate village areas based on the estimated travel costs from each cell to the village location. A reduced-form, multinomial logit model is used to estimate the influence of hypothesized determinants on land use and the probabilities that a certain pixel has one of five land-cover classes during either of the two periods under consideration.Results suggest that the first period from 1975 to 1992 was characterized by land-intensive agricultural expansion and the conversion of forest into grass and agricultural land. During the second period, since 1992, the rapid, more labor-and capital-intensive growth in the agricultural sector was enabled by the introducti-III IV ABSTRACT on of fertilizer, improved access to rural roads and markets, and the expansion of irrigated areas. These policies, combined with the introduction of protected forest areas and policies discouraging shifting cultivation during the second period reduced the pressure on forests while at the same time increasing agricultural productivity and incomes for a growing population. Forest cover during the second period mainly increased due to the regeneration of areas formerly used for shifting cultivation.Policy simulations mimic the influences from potential policy interventions on land use. Land-cover categories for the policy simulations are aggregated to three classes and a spatial sample is drawn to concentrate the analysis on changes influenced by anthropogenic interventions. In that way, the focus of the simulations is on land-use changes within already cultivated areas and at the agricultural frontier where most land-use changes relevant for policy makers take place. The simulations are limited to the second period from 1992 to 2000 as this is the relevant period for potential policy measures.The four rural policy scenarios are carried out for low and high levels of investments in irrigation facilities, for an enlarged area under forest protection and for a combination of high investments in irrigation combined with increased forest protection, an often mentioned...

“…Institutions not only govern the processes by which scientific and technical knowledge is created, but also facilitate the promotion of new agricultural technologies for improved agricultural production (Hayami and Ruttan, 1971). Infrastructure, including transportation facilities, and access to market centers also make equally important contributions to land-use change by providing opportunities for locationally suitable and economically attractive land-use systems (Allan, 1986;Turkelboom et al, 1996;Reardon et al, 2001).…”
