  • The rain forest takes an immense breath and then exhales, once every four or five years, as a major global weather pattern plays out, usually heralded by El Nin˜o–Southern Oscillation. While this powerful natural cycle has occurred for many millennia, it is during the past decade that both the climate of Earth and the people living on it have had an increasing influence on the weather pattern itself, with many biological consequences. In Southeast Asia, as also in most of the Neotropics, El Nin˜o accompanies one of the most exuberant outpourings of nature’s diversity.

  • The soils of the South American llanos and cerrado grasslands are predominantly old soils from which most of the plant nutrients have been lost. In many places there are layers of laterite (see the sidebar), which give them a red or yellow color. African savanna soils are much younger and more fertile. These shade into arid soils in the north and into wetter soils on high ground. On the southern side there are poor, exhausted, lateritic soils typical of tropical rain forest.

  • Ondjiva, an Angolan town on the border with Namibia, often goes for years without significant rainfall. When it does rain, floods sweep across the flat ground leaving little stored for future use.

Others buy from men like Antonio - his barrel weighs nearly ¼ tonne, and it will have taken him much of the day to roll it into town, earning him around 20 pence. Many people can afford neither; meaning girls and women must spend time...
