Rachael Garrett is an Assistant Professor of Environmental Policy at ETH Zürich (Switzerland). Dr. Garrett's research examines interactions between land use, ecosystem services, and economic development at multiple spatial and temporal scales to better understand the drivers and impacts of land change and the effectiveness of existing conservation policies and practices. She is particularly interested in how commodity supply chains interact with environmental institutions to shape land use processes, resource distribution, and trade. Her research has largely focused on land change processes in agriculture-forest frontiers and sustainable intensification of pastures in the tropics. More recently she is leading a pan-tropical analysis of the effectiveness and equity of forest-focused supply chain policies with funding from the Swiss National Science Foundation and an ERC Starting Grant. This work involves coordinated research in Brazil, Ghana, Indonesia, and Ivory Coast on beef cattle, cocoa, oil palm, and soybean supply chains. Dr. Garrett received her doctorate at Stanford University and did her post-doctoral fellowship at Harvard University. Prior to working at ETH Zürich she was an Assistant Professor at Boston University.

Effectiveness-equity tradeoffs in enforcing exclusionary supply chain policies: Lessons from the Amazonian cattle sector

To address ongoing deforestation for global food commodities production, companies and governments have adopted a range of forest-focused supply chain policies. In the Brazilian Amazon, these policies take the form of market exclusion mechanisms, i.e., immediately dropping suppliers who have cleared...

Designing effective and equitable zero-deforestation supply chain policies

In response to the clearing of tropical forests for agricultural expansion, agri-food companies have adopted promises to eliminate deforestation from their supply chains in the form of ‘zero-deforestation commitments’ (ZDCs). While there is growing evidence about the environmental effectiveness ...

Criteria for effective zero-deforestation commitments

Zero-deforestation commitments are a type of voluntary sustainability initiative that companies adopt to signal their intention to reduce or eliminate deforestation associated with commodities that they produce, trade, and/or sell. Because each company defines its own zero-deforestation commitment g...
