Overview

Background

How do we feed the world, adapt to and mitigate climate change, and conserve biodiversity? My research addresses these critical questions by quantifying the trade-offs between agricultural production, climate change, and biodiversity in tropical agricultural landscapes. A key focus of my work is agroforestry—the strategic integration of trees into cultivated lands. While agroforests are not a one-size-fits-all solution, my research shows that agroforestry, when informed by a quantitative understanding of these trade-offs, can improve biodiversity and climate outcomes without compromising agricultural productivity.

Through fieldwork and conservation planning, and in collaboration with my wonderful colleagues at the Centre for Biodiversity and Conservation Science (CBCS), I aim to understand how agricultural landscapes can be optimized across large geographic areas, to best meet conflicting goals and improve biodiversity outcomes. The goal of this work is to improve sustainability outcomes across West Africa, where tropical forests have been rapidly converted in order to produce 60% of the world’s cocoa.
