The small volcanic and limestone islands of the Lesser Antilles, in the eastern Caribbean, have a continuous history of commercial agricultural production which goes back 370 years. During this period, conditions of the environment, both natural (volcanoes, earthquakes, hurricanes, droughts) and human‐induced (deforestation, erosion, land degradation and reduction in the water‐table), have interfered with development in a variety of ways. The paper reviews past and present situations, and considers how growing sectoral imbalances may accentuate the resulting problems.  相似文献

The object of this work was to relate the corrosion of tin-bronzes to the chemical condition of the soil in which they have been buried, most of them since the Bronze Age. Naturally, it was not easy to obtain recent hoards with their related soils, and considerable reliance had to be placed on recorded finds by taking recent soil samples from sites on which hoards were found over a hundred years earlier. Even so, with the exception of peat, a reasonable relationship appears to exist between the pH of the soil and the state of the metal. Acid soils are aggressive to metals and alkaline soils are benign. In no cases were sulphate reducing bacteria active in promoting corrosion. In the main, peat and peaty soils were benign in spite of their acidity, probably due to the protective action of polyphenols.  相似文献
