Drought is a large-scale problem. Droughts of high severity, long duration, and broad spatial extent happen infrequently enough that ecological and economic dependencies on water are bound to develop during the between-drought intervals. The trick for drought resilient societies is to develop a long-term memory that serves to limit over-enthusiastic exploitation of water resources when…
