Hydrological processes maintain wetlands, whose position in the landscape determines their character and possible response to climate change. We studied such responses to long periods of climate change in a large groundwater fed fen (Mfabeni Mire), w

In southern Africa, wetlands of different types are an integral part of the drainage network, yet evolve and are sensitive to different combinations of geologic, climatic, geomorphic, edaphic and hydrologic controls. Understanding of these controls c
