Challenges and Opportunities of On-farm Tree Planting as an Alternative Wood Source on Mt. Marsabit, Northern Kenya: Towards Mitigating Climate Change
Challenges and Opportunities of On-farm Tree Planting as an Alternative Wood Source on Mt. Marsabit, Northern Kenya: Towards Mitigating Climate Change
摘要
Constraints and probable pathway towards increasing tree density and diversity within farmlands as a means of reducing human dependency on Mt. Marsabit forest for wood are addressed. The forest provides a carbon sink to counteract the risks and hazards associated with climate change. A structured questionnaire was administered to a sample of 205 respondents that were selected from a population of 3075 farming households using a systematic random sampling procedure. While majority of the farms (53%) had low tree density (1-10 trees), only 8% of the farms had high density (≥ 20 trees). About 50% and 15% farms had Grevelia robusta and Eucalyptus cammudelensis, which were grown for timber production, respectively. Broad leafed trees, like Croton megalocarpus and Moringa stenoptella had been established in 17% of the farmlands, respectively. With only 20% of the households having a fence around the crop fields, coupled by widely inter-household sharing of crop residues for grazing, tree browsing by livestock was a constraint to tree establishment. The challenges present an opportunity to establish governance structures and processes for communal responsibility and management of tree resources in the farms. A plausible approach entails the Adaptive Collaborative Management (ACM) as a process that facilitates to experiential learning and negotiation for probable actions and policies in management of natural resources.
