The Agroforestry project investigated the use of sustainable agroforestry for carbon sequestration to improve small farmers’ livelihood in the tropics. Our research site was located in Sardinilla, Panama.
This project had a twofold objective, which was investigated in two subprojects. Our group was working on Subproject 1 while the Applied Entomology Group of Prof. Silvia Dorn was working on subproject 2.
Subproject 1 aimed at assessing the response of plant productivity to future climate change in different land use systems in Panama and to quantify their carbon sequestration potentials, providing baseline information for adaptive management decisions and the very first data sets to policy-makers. Thus, carbon dioxide and water fluxes were measured continuously using two flux towers, one in a traditionally grazed pasture and one in an improved afforestation system (with native tree species), in order to quantify carbon sequestration potentials of these land use types in Panama.
Subproject 2 aimed at taking novel natural-based approaches to increase plant health and reduce insect pests in afforestation and silvopastoral systems. This subproject shall support timber tree establishment on current pastures as a future source of income to rural poor.
This project was funded by the North-South Centre (originally by ZIL - Swiss Centre for International Agriculture, a competence centre of ETH Zurich).
