Book excerpt: "This book is a guide to why environmental rehabilitation is necessary, the standard to which it should be done, and how to do it. Using the South African Constitution as the ultimate frame of reference, the guide explains, for any given case, derivation of a rehabilitation objective, its boundary conditions, the interventions to be applied, and simple powerful metrics that can be used to measure achievement. Focuses on rehabilitation in the humid and semi-arid regions of South Africa."--
