This report entitled "Forests, Trees and Landscapes for Food Security and Nutrition" presents the results of the fourth global scientific assessment undertaken so far in the framework of GFEP. Previous assessments addressed the adaptation of forests and people to climate change; international forest governance; and the relationship between biodiversity, carbon, forests and people. All assessment reports were prepared by internationally recognised scientists from a variety of biophysical and social science disciplines. They have all been presented to decision-makers across relevant international policy fora. In this way, GFEP supports a more coherent policy dialogue about the role of forests in addressing broader environmental, social and economic challenges.
