Climate resilient traditional agroforestry systems in Silite district, Southern Ethiopia

Abstract

Agroforestry is recognized as one of the strategies for climate change mitigation and adaptation under the Kyoto protocol. The system has been practiced in Ethiopia for a while by smallholder farmers by incorporating crops with trees providing extensive socio-economic and environmental benefits. This unaccounted benefit of the system needs further and specific study. Thus, this study aimed to examine the resilience of three (homegardens, woodlots, and parkland) traditional agroforestry systems (TAFS) on the basis of biomass carbon accumulation and socio-economic characteristics in Silite district, Southern Ethiopia. Systematic random sampling was employed to collect social and biological data. Height and diameter at breast height (DBH) were measured to determine the biomass carbon stock and a questionnaire was performed for the socio-economic data. The mean differences across the system were analyzed using a post hoc test. Socioeconomic data were analyzed using descriptive statistics and the chi-square test. Climate change awareness was perceived almost by half of the respondents, thus the contribution of TAFS to climate change adaptation and mitigation was revealed socio-economically and ecologically. Carbon stock and socio-economic benefits gained from agroforestry systems consist in a great sink of carbon and food security.
