This research project came about in response to the proposed introduction of various so-called "wonder-crops" into South Africa, amongst them Jatropha curcas. Interest centred on poverty alleviation, job creation and the provision of alternative energy sources; however, questions regarding the hydrological and ecological effects of large-scale cultivation of these crops were unable to be answered. Indeed, confident quantification of the impacts of these species on water resources was not possible, because of insufficient research worldwide. The effective management of commercially planted species in terms of water resources requires accurate data on generalised water use and bio-physical patterns, relevant to areas having planting potential. This was the approach followed in this project, which strove to gain an understanding of the biophysical requirements and associated water-resource impacts of J. curcas.
