Enrique Leff

He is best known for arguing that environmental problems result from a crisis of Western civilization's ways of knowing, understanding and transforming the world (Eschenhagen 2012). This masks other legitimate ways of thinking and acting in the world, namely forms of 'eco-development' and environmental rationality. His work is largely theoretical but his major books cite positive examples of the ethnobotanic practices of Prehispanic cultures in Latin America, sustainable agricultural practices in tropical ecosystems, etc.
