Feasibility Study of Mangrove Rehabilitation using Guludan Technique in Carbon Trade Perspective in Protected Mangrove Area in Muara Angke, DKI Jakarta Province

Abstract

Mitigation of climate change due to CO2 emissions, the forestry sector developed a REDD+ scheme. This study was conducted to examine financial feasibility of the mangrove rehabilitation with guludan technique, so that further funding of man-grove rehabilitation can be included into REDD+ scheme. Guludan technology was developed to overcome the deep water column for mangrove rehabilitation in the former pond area. This technique has been developed for mangrove species Avicennia marina with spacing 0.25 m x 0.25 m, 0.5 m x 0.5 m, and 1 m x 1 m. Based on diameter and height growth of 36 months planted seedlings of A.marina followed logistic model. CO2 sequestration 386.34 t/ha, 131.12 t/ha, and 26.75 t/ha in 0.25 m x 0.25 m, 0.5 m x 0.5 m, and 1 m x 1 mspacing. With CO2 sequestration selling price of €20,00/t CO2 and rehabilitated land area of 10 ha, this rehabili-tation action using guludan technique is not financially feasible, because the criteria for a negative NPV, Net B/C< 1, and IRR
