“…Forests were located primarily away from roads, in protected areas, or in locations not favored for agriculture. Other researchers also have found a strong relationship between the location of roads and forest clearings at both local and national scales (e.g., Sader and Joyce 1988, Veldkamp et al 1992, Sader et al 1994, Sader 1995.…”

land uselcover change, Costa Rica, tim-series, landscape metrics.A time-series of aerial photography and Landsat TM data were compiled for an area of the Caribbean lowlands of northeastern Costa Rica from 1960-1996. Oeo-referenced, ground-based information was collected in 1996 and 1997. Changes in land cover were mapped and landscape fragmentation was examined using landscape pattern metrics. By 1996 the area was characterized by a complex mosaic of forests, pastures, and crop lands of different ages and disturbance histories. The most important forces driving land use changes were colonization, infrastructure development, and changes in export markets, but the spatial patterns of land use change were determined by the physical landscape. In terms of long-term forest health and conservation, there are three considerations: (1) whilst forests remain an important component of the unprotected landscape in the region, and deforestation rates have declined, the forests are highly fragmented and the area exposed to edge effects is high; (2) the secondary forests in the area are young and transient in nature; and (3) never cleared forests are in good condition, but they are susceptible to disturbance in the future.

“…This trend is corroborated by the greater deforestation observed near roads (Sader et al, 1994;Chomitz & Gray, 1996;Pfaff, 1999). In several cases, this dual process appears to be driven at the farm level by relatively wealthy households who are the most able to afford intensification in the form of inputs, machinery, and hired labor, and who are also the most able to expand farm holdings (Pichón, 1997a,b).…”

Forest conversion for agriculture expansion is the most salient signature of human occupation of the earth's land surface. Although population growth and deforestation are significantly associated at the global and regional scales, evidence for population links to deforestation at micro-scales-where people are actually clearing0020forests-is scant. Much of the planet's forest elimination is proceeding along tropical agricultural frontiers. This article examines the evolution of thought on population-environment theories relevant to deforestation in tropical agricultural frontiers. Four primary ways by which population dynamics interact with frontier forest conversion are examined: population density, fertility, and household demographic composition, and in-migration.

“…They found that more than 90 % of the deforestation is located within a 3 km distance of streets and rivers. Sader et al (1994) (1986)(1987)(1988)(1989)(1990) and a growth of 0.03 %. That means a disparity of 12:1 regarding the relationship between deforestation and growth.…”
