Forest and trees are vital for people around the world, not only as a source of food and income for rural poor populations but to sustain our ecosystems.
Yet the areas where people are most dependent on forests and trees for their food and livelihoods are often the same areas that are under increasing threats from climate change, [1] pests and diseases, and deforestation.
Many organizations seek to conserve the biodiversity of forest tree species but Bioversity International focuses particularly on the diversity within tree species.
We have developed regional programmes to carry out this work with partner organizations in Asia [2], Latin America [3], Africa [4], and Europe [5]. We also work within the CGIAR [6]-wide system on projects related to forests, trees and agroforestry. [7]
