Mark Buntaine investigates how improved governance can support the implementation of environmental policies in low- and middle-income countries. In the past several years, he led experimental projects that tested whether citizen participation in policy implementation improved solid waste services, reduced air and water pollution, and strengthened forest management. He collaborates with and advises governmental and non-governmental partners on the effective implementation of environmental policies, with a focus on designing institutions that ensure governments are accountable to the people they serve.
