Mangroves are the only protection in the tropics against coastal erosion, are nursery grounds for a variety of marine animals and increase sedimentation of particles brought to the coast by rivers. Mangrove distribution in the tropics and subtropics is often linked with the presence of estuaries and creeks. There is a consensus that the brackish water micro environment is caused by river discharges into the oceans. However all over the world mangrove areas are found where no rivers or estuaries are in the immediate neighbourhood. An explanation is reported here for a number of those exceptions. Using a mathematical groundwater flow model it is shown how human activities as far as several hundreds of kilometres inland can destroy vast areas of mangroves by changing the groundwater flow. The model predicts and/or confirms the destruction of large mangrove areas in Kenya and in Florida (USA).
