Agroforestry as plant production system in a multifunctional landscape. Inaugural lecture upon taking up the special professorship in Agroforestry at Wageningen University 16 October 2014

‘Forests’ and ‘Agriculture’ have long been handled as separate domains of policy, institutions and science. That ‘theory of change’ needs to change itself. Agroforestry refers to the (re)integration of agro- and forestry. It includes trees on farm, farmers in the forest and the manifold interactions between agriculture and forestry as basis of rural livelihoods, as components of landscapes and as economic sectors. Integration of local, public/policy and science-based knowledge is needed to achieve sustainable development goals with and through trees.
