Abstract

Although Africa is not a major emitter of greenhouse gases from commercial and industrial energy uses, it accounts about 20–30% of emission due to deforestation and land use cover change. This study was conducted to estimate the carbon stock and its contribution to climate change disaster reduction in Zeghie peninsula, Ethiopia. Sample plots were laid along line transects based on altitudinal and slope variation of the study area. A total of 45 plots (40 m × 40 m each) were selected using random sampling techniques. The data obtained from each sample were analyzed by using allometric equations. The results revealed that the mean total carbon stock was 381.41 t/ha, of which 191.58 t/ha, 45.98 t/ha, 0.03 t/ha, 139.04 t/ha and 4.77 t/ha, which were observed in the aboveground carbon, belowground carbon, litter carbon, soil organic carbon in (30 cm depth) and deadwood carbon, respectively. The mean total CO2 equivalent of the study area was also 1399.78 t/ha. In relation to altitudinal gradients and slopes, the result showed that the stock of carbon was variable along the altitudinal variation with a mean value of 420.71t/ha, 458.78t/ha and 516.77t/ha in upper, middle and lower elevations, respectively. While a mean value of carbon along the slope gradient was 401.82t/ha, 439.26t/ha and 516.9t/ha in upper, medium and lower slope classes, respectively. Generally, the carbon stocks in aboveground, belowground, litter and soil organic carbon were exhibited less distinct patterns along altitudinal gradients. The aboveground, belowground, litter and soil organic carbon stocks showed decreasing trend with increasing altitude and slope while dead wood carbon stock showed increasing trend along altitudinal gradients. The total CO2 stored in Zeghie peninsula forestland was approximately 62,990.4 tons annually, but emission was estimated to be 8274.97 tons. Therefore, better management strategies should be designed for the sustainable use of forest resources in the study area which are contributing a significant role to mitigate the current climate change.

Acknowledgements

This study would never be completed without the contribution of many people to whom we would like to express our gratitude. The administrative kebele’s development agents, district agricultural officials, local youths, in each of the sampling sites were indispensable for the successful completion of the field work. We would like also to acknowledge people who contributed their knowledge and time in data collection and other reliable supports.
