Agroforestry is a dynamic, ecologically-‐based, natural resource management pracHce that, through the integraHon of trees on farms and in the agricultural landscape, diversifies and sustains producHon for increased social, economic and environmental benefits.
Trees in forests and on farms
Collaborative programmes in different ecoregions
Some of the most fundamental contribuHons of trees in fields, farming landscapes and forests are as direct inputs to the livelihoods of resource-‐poor rural people. Appropriately managed trees help diversify rural livelihoods and contribute to the sustainability of agricultural producHon through Hghter nutrient and water cycling

ENSEMBLE
agreement between 14 models on the predicted presence of a species
For species with sufficient point data
Tree diversity analysis • A free manual and soeware for biodiversity analysis, applied (among
other research domains) for on-‐farm diversity analysis • Ensemble suitability mapping methods will be expanded
