Patrick Bigger is an economic geographer at the Lancaster Environment Centre (UK) exploring how nature is made investable and to what ends. His work on financial-environmental entanglements spans settings, types of investment, and market structure from California’s cap-and-trade carbon market to the global green bonds market to for-profit biodiversity entrepreneurs in Kenya to World Bank green infrastructure finance. His other research project deals with the political economy and ecology of the US military, which has been covered extensively in the global press. His work appears in journals such as Transactions of the Institute of British Geographers, Environment and Planning: E: Nature and Space, and The Journal of Environmental Investing.
