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

Decision-‐support tools for species selecHon

“ICRAF have a ni@y new tool out called Useful Tree Species for Africa. I’ve been playing around with it and I have to say it’s impressive.” Luigi Guarino h>p://agro.biodiver.se/)

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
