The northern half of the parish of st. catherine .in Jamaica was selected as a test area to study 1 by rreans of rerrote sensing, the problerrs of soil erosion in a tropical environment. An initial study was carried out to determine whether eroded land within this environment could be successfully interpreted and mapped from the available 1: 25, a::xJ scale aerial photographs. When satisfied that a sufficiently high percentage of the eroded land could be interpreted on the aerial photographs the main study was initiated. This involved interpreting the air photo cover of the study area for identifying and classifying land use and eroded land, and plotting t..lJ.e results on overlays on tOfX)graphic base maps. These overlays were then canposited with data on the soils and slopes of the study area. The areas of different soil t"tpe/slope/land use canbinations were then rreasured, as was the area of eroded land for each of these combinations. This data was then analysed in two ways. The first way involved deter:mining which of the combinations of soil type, slope and land use were most a.'1d least eroded and, on the basis of this, to draw up recomrendations concerning future land use. The second analysis was aimed at deter:mining which of the three factors, soil type, slope and land use, was rrost responsible for dete:rmining the rate of erosion. Although it was possible to show that slope was not very significant in detennining the rate of erosion, it was nruch rrore difficult to separate the effects of land use and soil type. The results do, however, suggest that land use is rrore significant soil type in detennirling the rate of erosion within the study area.
