摘要

Compiled information on parkland agroforestry tree species in relation to diversity, tree management options and the challenges of the system is important for production and productivity, and biodiversity conservation through availing the required information which in turn has an implication to the sustainability of the system and climate change mitigation. So, the aim of this review paper is to compile information on parkland agroforestry practices of Ethiopia, particularly: on tree species diversity, their roles, management options available and challenges of the practice. Parkland agroforestry which is a system practiced by many local populations comprises the large part of agricultural landscapes in Ethiopia and is very important in different aspects such as;for food security, microclimate amelioration, economic benefits, environmental protection, household energy, household utensils, cultural values, traditional medicines, and fodder. There are many indigenous multipurpose tree species scattered on farmlands in Ethiopia, and the common one includes: Millettia ferruginea, Cordia africana, Ficus vasta, Ficus sur, Croton macrostachyus and Faidherbia albida. However, nowadays these trees are facing challenges like: expansion of exotic trees in the expense of the native ones, expansion of cash crops through removal of the parkland trees from the farm area, climate change, land shortage and tenure system which require high emphasis for the production and productivity as well as sustainability of the system especially, in this era of climate change;hence this system is one of climate change mitigation options.
