Over vast areas of the world, and particularly in Africa most risk and disasters are associated with drought and flood both increasing in severity and frequency. Not as a result of climate change as so often touted but being symptoms of non-effective rainfall or desertification. These regions not being subject to tsunamis, volcanic eruptions, hurricanes, etc. Allan Savory brings this to crystal clarity in this graphic example, which shows that very differently from theoretical models of effective rainfall (r.g. FAO) it is the local practices on the land that most influence rain’s effectiveness.
