An estimated 540,000 hectares of good arable soil existed in Haiti in 1938. By 1954 the figure had shrunk to 370,000. By 1970 it was 225,750 hectares, and the figure reported for 1985 was 205,000, with no sign afterwards that the trend had reversed. In the mid 1980s between six thousand and ten thousand hectares of arable land were being lost each year, and in the early 1990s the range ran from six thousand to fifteen thousand. The mechanism is a substitution. As the rural population grows, labour intensive food crops replace land intensive export crops, above all replacing coffee, whose roots and canopy hold the soil, on steep hillsides. Food crops are cleared and replanted in the rainy season, when the ground is soft, and the downpours then wash the soil into the valleys and streams. Once running, the process feeds itself without further population growth.
