What southern Africa can learn from other countries about adapting to drought

The experience of other countries may offer useful lessons. Not all will be applicable, given southern Africa’s limited financial resources. For example, southern African countries cannot afford wasteful expenditure on infrastructure, so we must be sure that our predictions of future water demand and changes in water availability have low uncertainty. Individual low-income households in southern Africa cannot afford some of the water-saving technologies used in developed countries. So it needs to adopt simple, but effective solutions.
