Opis:: Climate change is one of the most critical threats to the human population and other living organisms on Earth. REDD+ is developed as a mechanism to acquire a global fund for addressing climate change, deforestation, and protecting the forest ecosystem while maintaining the livelihood of local communities. As a response to the need for carbon stock measurement at the specific forest and land-use types, this research aimed to estimate the aboveground carbon stock at seven land-use types in KPHP (Forest management unit) Katingan Hulu Central Kalimantan Indonesia. This research was conducted from May to September 2019. The data collected in 91 observation plots included diameter at breast height, total height, and fresh weight of understory vegetation and litter. Using an allometric equation, this research estimated the above-ground carbon stock in trees, understory vegetation, and litter. It was found that AGC varied across different land-use types: secondary peat forest 135.30 Mg C/Ha, secondary forest 212.19 Mg C/Ha, shrub 47.41 Mg C/Ha, oil palm plantation 73.76 Mg C/Ha, rubber plantation 65.56 Mg C/Ha, and forest with rattan 75.98 Mg C/Ha. It was concluded that AGC in KPHP Katingan Hulu varied according to the type of land use system. The forests with less human intervention, such as secondary forests, had higher AGC compared with highly disturbed forests such as shrubs. The findings from this research could help decision-makers to develop the REDD programs to rehabilitate forests and contribute to community development.

Opis:: Soil macrofauna can be an indicator of changes to the ecosystem. This study aimed to investigate the biodiversity of soil macrofauna in jelutong-based agroforestry on peatlands. Line transect sampling was used, eight transects and 32 plots were established. The sample was collected using the hand sorting technique. Species diversity and species evenness were determined using Shannon-Wiener index, while species richness with Margalef index. This study found 2179 individuals of soil macrofauna that belong to six classes, nine orders, and 13 families. The Formicidae 1 family dominated the area (951 individuals), while Lumbricidae had the least number (13 individuals). This study indicates that the species diversity of soil macrofauna in the jelutong-based agroforestry on peatlands is moderate (H’ = 1.508) with moderate species evenness (E = 0.588) and very high species richness (DMg = 281.788). It implies the capacity of the system in providing suitable habitat for macrofauna, and that it can be a potential alternative for ecological restoration in peatlands.

Opis:: Peat forest plays a principal role in climate change mitigation in Indonesia. Considering the potential releases of GHGs from a forest fire and degraded peatland, it is important to conserve peatland forests. Besides being essential for ecological balancing, the role of peatland forest expands to the economic and social aspects. The purpose of this research was to calculate $CO_2$ emissions that can be avoided by the community-based fire prevention and rewetting program. This research utilized spatial analysis to calculated avoided $CO_2$ emissions in six villages in Central Kalimantan. Data and information for the calculation were generated from field observations, interviews, and desk study. Spatial analysis using Arc GIS 10.5 was applied to compute the incombustible areas. The result from the analysis found that fire prevention and rewetting programs managed to prevent approximately 1 million Mg C or equivalent to 3.7 million $CO_2$. The program managed to prevent emission from the vulnerable area including swamp shrubs, plantations and dry land agriculture. The finding of this study suggests that community-based fire prevention and peatland rewetting programs could become a strategic program in climate change mitigation in Indonesia.

Opis:: Hampangen Education Forest (HEF) has great potential in terms of carbon stock, biodiversity, and contribution to the local community’s livelihood. In the future, it is planned to develop its role in climate change mitigation; thus, valid and updated information regarding climate regulation services are required. The purpose of this study was to assess the above ground biomass (AGB) at different canopy densities of swamp secondary forest in (HEF) and estimated the total AGB stored in this area. The research was carried out from April 2022 until July 2022. The data collected included tree diameter at breast height (DBH), tree total height, the weight of litter, and understorey vegetation. All the information was collected using two types of observation plots (400 m2 and 0.25 m2) and AGB was calculated using allometric equations. This research found that the average AGB at sparse, medium, and dense canopy cover was 70.46 Mg.ha-1, 80.94 Mg.ha-1, and 145.03 Mg.ha-1, respectively. The total AGB stored in HEF was 367,180.08 Mg (tonnes) and equivalent to above-ground carbon stock of 172,574.64 Mg carbon. The finding of this research suggests that HEF needs conservation strategies to improve its carbon stock and conserve biodiversity.

Opis:: Peatland rehabilitation is an urgent need in order to minimize the effects of peat degradation and to support climate change mitigation. However, the rehabilitation of degraded peatlands still faces many obstacles. This study aimed to study the agroforestry system on peatlands applied by traditional communities as an effort to discover a peatland rehabilitation strategy. This research was conducted in the Pilang, Tanjung Taruna, and Kalampangan villages from February to August 2019. The data in this study were obtained through field observations, interviews with the community, and Focus Group Discussion. The data was then synthesized using descriptive statistics. The results of data analysis showed that in the study area, six types of agroforestry systems were found. Communities develop different agroforestry systems at various types of peat depths. Farmers develop vegetable and fruit-based agroforestry on shallow peat, rubber-based agroforestry, annual crops and fruit on medium peat, fruit and rubber forestry plants on deep peat. Most farmers planted endemic species including Rubber (Havea braziliensis), Galam (Melaleuca leucadendra) and Gerunggang (Cratoxylum arborescens). The results of this study can be adopted as a peatland rehabilitation strategy since they are in accordance with the socio-culture of the local community and capable to accommodate economic and conservation interests.

Opis:: Food security is one of the main problems under the pandemic and climate change condition that we currently face. Managing peatland to fulfill community needs faces several problems including peat fire, GHG emissions and loss of biodiversity. Agroforestry is one of land use systems on peatland that is capable of accommodating different interests while still concerning the conservation purposes. This study aimed to assess the potential of agroforestry for ensuring the food security of local communities. This research was carried out in the Kalampangan Village, Palangka Raya City central Kalimantan for six months. This study used both quantitative and qualitative approaches, including interviews and field observations. Interviews were carried out with 13 farmers in Kalampangan who applied an agroforestry system. The data gathered included all agroforestry components and number of the food production component. The data were analyzed using descriptive statistics. The results showed three agroforestry types were applied by the Village community Kalampangan, namely agrosilviculture, agrosilvopasture, and agrofisheries. The biodiversity of agroforestry in Kalapangan is relatively high, with a total of 58 different species identified. A total of 86% of all agroforestry components are sources of food, including fruits, vegetables, seeds, tubers, spices and livestock. The information above shows that the peatland agroforestry in the Kalampangan Village has the potential to support food security while maintaining the biodiversity. Thus, agroforestry can be recommended as a peatland land use and rehabilitation strategies to accommodate the basic needs of local communities and increasing their prosperity.
