Space Matters

Economic and ecological processes interact with one another over both spatial and temporal dimensions.This dissertation explores four socio-ecological systems where space crucially matters for both economic and ecological outcomes. In the first chapter, a windborne chemical dictates the diffusion in space of a new agricultural technology. The second chapter dissects the notion of landscape complexity to find which of its components matter for the intensity of insect pressure in agriculture, and thus the use of insecticides. In the third chapter, the location of participants in an environmental program seeking to curb deforestation points to additionality problems and anticipates the lack of measurable effects of the program. Knowing where crops are grown and temperatures less well-suited for their thriving is key to identifying in chapter four the effects of weather fluctuations on asylum applications into the European Union. The spatial dimension tends to be hard to apprehend and overlooked, but those four pieces together stress that space matters in the study of sustainable development.
