I am compiling a series of historical case studies of transformative adaptation to major environmental changes, such as dryland salinity brought about by land clearing and changes in water availability due to high irrigation diversions and so on. I am keen to learn of examples that provide a perspective on social processes and decision making in relation to adaptive responses by people, particularly that relate to changes in societal values relating to the environment, how knowledge was used to scope choices for adaptation and how rules (legislation, policies, behaviours and norms) either enabled or constrained those choices. Any pointers to relevant literature would be gratefully received.
