Joachim Ayiiwe Abungba from the University of Science and Technology in Ghana and colleagues from India used a water evaluation and planning model to estimate runoff, streamflow and future water demand under different climate scenarios. They reveal that between 1990 and 2019, human settlements, open savannah woodland, croplands and waterbodies increased, while closed savannah woodlands, wetlands and grasslands decreased. The model shows increased water availability from river discharge compared with the current scenario. However, the uncertainties in future changes exceeded the predicted increases. There is an urgency to further improve model certainty and to develop integrated water management in order to ensure sustainable livelihoods for local people.
