Sheil, D., & Bargués-Tobella, A. (2020). More trees for more water in drylands: myths and opportunities. ETFRN News.
The restoration of tree cover influences water availability. Many people—some experts too—believe incorrectly that greater tree cover has an invariably negative impact on local water availability. Where do these beliefs come from? Here we summarise the origin of these misconceptions and illustrate how tree cover can improve water availability. We have recognised the extent of these opportunities only recently, and considerable work remains, but we know enough to dismiss some myths and to highlight major opportunities to improve water security in Africa by restoring degraded landscapes with trees.
