Abstract

Tiwoho mangrove forest islocated in north coast of North Sulawesi province.This area functions as life buffer system for community and sustainability of Bunaken National Park. Due to the important and strategic roles of mangrove in protection and ecological functions, therefore, it is needed to know scientific information about mangrove population dynamics. This research aims to know the vegetation composition and structure vegetation of Tiwoho mangrove forest. Data collection used 20x20 m sample plots that were sistematically laid from the sea to the land side up to the highest tidal line. Distance between plots along 25 m. Results showed that at tree level Sonneratia alba had the highest Important Value Index (IVI) of 206,88 % and Brugueira sp of 46,06 %. Although Rhizopora apiculata value is lower than Brugueira sp. But the values of relative frequency of these species are almost similar. It means that both species are frequently found in observation plots. Rhizophora apiculata dominate at pole and sapling levels, but frequency of occurance this species is lower than Brugueira sp in pole level.

Abstract

The development of remote sensing technology makes it possible to utilize its data in many sectors including forestry. Remote sensing image has been used to map land cover and monitor deforestation. This paper presents utilization of ALOS PALSAR image to estimate and map aboveground biomass at natural forest of Bogani Nani Wartabone National Park especially SPTN II Doloduo and SPTN III Maelang. We used modeling method between biomass value from direct measurement and digital number of satellite image. There are two maps which present the distribution of biomass and carbon from ALOS PALSAR image with 50 m spatial resolution. These maps were built based on backscatter polarization of HH and HV bands. The maps indicate most research area dominated with biomass stock 0-5.000 ton/ha.

Abstract

The land use and land cover change phenomenon has brought social and economic benefits such as agricultural land expansion, which increases food production for a rapidly growing population. On the other hand, it has also been reported to impact terrestrial ecosystem change and its service, including climate change control. The study aimed to estimate CO2 emission from land use and land cover change in Banyuwangi during 1995–2019 and formulate mitigation options to reduce CO2 emission. Four satellite images from 1995, 2000, 2014, and 2019 were used to classify land use and cover and then investigate the changes. This study applies a historical-based approach to estimate emissions to project future emissions using REDD Abacus SP software. There are 12 land use and land cover based on supervised classification: primary forest, secondary forest, plantation forest, mangrove forest, plantation, settlement, cropland, paddy field, shrubs, water, fishpond, and barren land. The land use and land cover change during the period 1995 to 2019 increased both CO2 emissions and sequestration. From 1995 to 2019, land use and land cover change in Banyuwangi emitted 1,5 million tons of CO2-eq/yr and sequestered 0,5 million tons of CO2-eq/yr. Under Business as Usual (BAU) or without mitigation effort, the emission will decrease to 1,2 million tons CO2-eq/yr in 2030. The implementation of the Regional Spatial Plan (RSP) prepared by the Banyuwangi Regency Government is projected to reduce emissions by 47.59% of net emissions from emission without mitigation. If the RSP scenario is added with efforts to prevent deforestation, net emissions can be reduced by 89.21%. Implementing Banyuwangi RSP can become best practice mitigation because it prioritizes the balance of protected areas and cultivation and maintains economic growth.
