 Southern Africa has its own network of information sharing called SEARNET, which informs farmers of techniques to catch and store rainwater, with some seeing increased yields and additional harvests.This new network of farmers sharing their ideas with each other has led to a spread of both new and old ideas, and this has led to greater sustainability of water resources in the countries of Botswana, Ethiopia, Kenya, Malawi, Rwanda, Tanzania, Uganda, Zambia and Zimbabwe.This water could be used for agriculture or livestock, or could be fed through a purifier to yield water suitable for human consumption.
