| While some features of environmental variation, such as the intertemporal variation in rainfall, have received very considerable attention, one feature which has been largely overlooked is the local variability of rainfall and other environmental factors. By local variability is meant the extent to which different nearby villages may receive different amounts of rainfall in the same day or month. Recent studies, several of which are reported in the papers done under this IRIS project, have shown that a common characteristic of arid and semi-arid tropical regions (ASARs) is the existence of relatively low correlation coefficients among daily (or monthly) rainfall observations taken at relatively nearby locations. Therefore, it is this characteristic of ASARs which constitutes the focus of present studies. |
