Carbon and economic benefits of community management of dry forests in Tigray, Ethiopia

Community management of forests may help meet human subsistence needs and mitigate climate change. The study was conducted to quantify the potential of community managed forests to accumulate carbon and simultaneous increase income. Twenty-four plots were randomly selected from managed natural forest, disturbed natural forest, exclosure and grazing land to quantify biomass and carbon. Tree and shrub biomass was estimated using a regression model while herbaceous biomass was determined using a total harvest. The impact of community forest on total income of the community was studied by taking landless sample households. A Propensity Score Matching (PSM) was conducted to measure the impact of the community forest on total income of the users. The estimated total biomass for managed natural forest, disturbed natural forest, exclosure and grazing land were 92.9 Mg ha-1, 33.4 Mg ha-1, 33.8 Mg ha-1 and 12.5 Mg ha-1, respectively. There was a significant difference in total biomass between the community forests and the grazing land (P<0.05). The carbon content of the living biomass for managed natural forest, disturbed natural forest and exclosure were estimated as, 43.6 Mg ha-1, 15.7 Mg ha-1, 15.9 Mg ha-1, while for open grazing the estimated carbon were 5.8 Mg ha-1. The carbon trading potential for managed natural forest, disturbed natural forest and exclosure was US
