| Summary: | This study aims to determine the contents of biomass, C content of biomass, loss of biomass and carbon, and absorption of CO2 by vegetation in various types of sub-optimal dryland use in Aceh Besar. The study was conducted on 12 land utility types (LUTs For each LUT, 5-6 sites were selected, and each location was repeated three times so that a total of 300 sample points were observed. The plant biomass measurement and calculation were differentiated according to the vegetation type. The biomass retrieval was based on The Indonesian National Standard Agency (BSN) procedure No. SNI 7724:2011. The primary forest was a land utilization type with the highest biomass contents, total C biomass, and CO2 absorption compared to other land utility types. The lowest was on bare land. The contents for biomass in the primary forest was 501.54±73.27 Mg ha-1, while in bare land, it was only 1.03±0.12 Mg ha-1 with C biomass content of 241.71 ±34.46 Mg ha-1 and 0.53 ±0.06 Mg ha-1, respectively. Total C biomass on sub-optimal dryland with an area of 239,387.91 ha was 26,728,46 Gg and could absorb CO2 of 202,735.14 Gg. Conversion of primary forest to open land can result in loss of C biomass from 37.1% to 99.8%. |
