- Ecological interactions, mainly in the tropics
- Ecosystem services, especially pollination
- Agroecology and functional biodiversity
My research focuses on the relationship between agrobiodiversity and ecosystem services in the new world tropics. For my PhD, I examine pollination and pest control services in cacao agroforestry systems with native varieties in Peru. I am studying the contribution of different insect groups to yields of native cacao across gradients of genotype diversity, local management and landscape context.
DiFFCacao investigates the interactions and importance of climate change, ecosystem services, agricultural management and socio-economic development in Northern and Southern Peru. Next to conserving genetic diversity of native cacao varieties, the objectives are enhancing productivity and farmers' income, in a wildlife-friendly manner. To achieve this, the development of innovative solutions for sustainable cacao agroforestry is central. The project is led by Bioversity International, in close cooperation with local, national and international project partners from research and practice.
