Wood production potential of different agroforestry practices and underlying production constraints in Tula woreda of Sidama regional State, southern Ethiopia
Keywords:
Agroforestry practices, crown volume, mixed species woodlot, silvicultural treatments, wood productsAbstract
On-farm trees have an essential role in supporting the livelihoods of the community in the study area thouth providing various wood products. The objective of the study was to characterize the attributes, constraints, and opportunities of on-farm wood production, with the view to increase farm wood production in the study area. Tula district was purposively chosen because it is among areas with a high concentration of smallholder tree growers. Both qualitative and quantitative methods were employed investigate farmers’ tree-growing conditions, constraints and to undertake tree inventory using selected potential wood production sites. The results of the study showed that home gardens, boundary planting, and woodlots were the three major agroforestry practices (AFPs) contributing to the production of 1,750 ± 292 m³ (Mean ± SE, ha) wood volume per annum in the area. Indigenous trees were investigated from natural regeneration while exotic ones were established through planting from seedlings. There were 20 tree species recorded in the three AFPs. As a constraint, the lack of access to planting material in terms of quality and quantity tree species was the major problem faced by farmers in the study area. Therefore, it is recommended that multidimensional intervention mechanisms with regard to improve tree management practices, facilitate determinant factors of production desired tree species, and improve extension services towards purpose-driven tree growing practices should be put in place to change the state of wood production in the study area.
