Abstract
The swamps associated with the complex fishpond ecosystems in Czechoslovakia, which have been under human management since about the 13th century, are now apparently threatened by modern hydrological and agricultural projects (Hejný, 1973). The floodplain soils of the lower Nile Valley and Delta have supported large human populations for 6000 years. Only late twentieth century technology has destroyed or damaged the natural system. The fact that such systems, which have been under man’s active management for so long, are now threatened by his own activities makes one appreciate immediately similar dangers in other areas. This is particularly true for wetlands of the tropics, where man has until recently either ignored or ‘reclaimed’ them, For instance, Fosberg (1973) observes: ‘The planner from a “developed” country usually finds it impossible to conceive of floods as anything but bad, so flood control usually accompanies “development” whether or not it is ecologically desirable’.
