How vegetation competes for rainfall in dry regions

Vegetation in semi-arid environments (or regions with low rainfall) self-organizes into patterns or "bands." Banded vegetation is common where there is low rainfall. In a paper published last month in the SIAM Journal on Applied Mathematics, author Jonathan A. Sherratt uses a mathematical model to determine the levels of precipitation within which such pattern formation occurs.
