PENYERAPAN KARBON PADA LAHAN AGROFORESTRI DI KABUPATEN LOMBOK TENGAH

Agroforestry is essential in climate change mitigation in West Nusa Tenggara Province. This study aims to estimate the potential for carbon sequestration in different agroforestry levels. The data collection method was field observation. The  Biomass estimation method was a non-destructive method using allometric models. ANOVA and Tukey HSD tests determine the carbon sequestration differences between agroforestry levels. The results showed that biomass, stock, and carbon sequestration increased frequently with increasing agroforestry levels. This condition is due to differences in the allocation of woody tree utilization space, which increased in advanced agroforestry. More established farmers implement the advanced agroforestry level with adequate resources. They can develop agroforestry silviculture more intensively, which supports optimal tree growth. Due to agroecological factors, the potential for carbon stock is still lower than the agroforestry system around the research location and the average in Southeast Asia. Likewise, the potential for carbon sequestration in the agroforestry system is still smaller than the regional CO2 emissions. The carbon emissions offsetting in the FOLU sector (forestry and other land use) are by increasing vegetation cover on land in forest areas with advanced agroforestry systems that the community has developed on their land. The government's role in agroforestry improvement is to increase community awareness and provide technical training, economic incentives, monitoring, and evaluation regularly. The study result is suitable as one of the inputs for establishing a sustainable agroforestry management plan. Expansion of the sample and research time can improve this study in the future.
