The dynamics of variations in carbon biomass in community forest and agroforestry in South Sulawesi

Abstract

Knowledge of the variation of potential carbon stocks in different types of forests provides information about the capabilities of each forest type in dealing with climate change mitigation. This research was conducted to determine the dynamics of carbon stocks in gofasa plantation community forests and compared to other land use systems in South Sulawesi. The research used sample plots 20 m x 50 m to measure tree biomass and 1 m x 1 m sub plots for undergrowth and litter. The results of the study indicated that there were variations of potential carbon stocks in plantation community forests and agroforestry. Carbon stocks in plantation community forest were varied according to the condition and age of forest stand. The total aboveground carbon stocks in homogenous gofasa stand ranged from 22.34 to 52.65 ton/ha by the difference in stand ages, while in mixed community forest was 77.60 ton/ha. As for agroforestry system, the carbon stocks ranged from 46.40 to 65.89 ton/ha. The dynamics of variations in carbon stocks in plantation community forest and agroforestry were determined by several variables such as species composition, stand age, and stand density. Therefore, a good management of community forests and agroforestry systems will ensure the mitigation of climate changes and environmental preservation through effective carbon storage.

Estimation of aboveground carbon stock using the 8 operation land imagery in Lemo Nakai community forest, Indonesia

“…Total carbon stocks that found at the dense canopy cover class was 179,14 tons/ha, the medium canopy cover class stored 128,29 tons ha-1, and the lowest canopy cover class had 68.67 tons ha-1. Therefore, The Lemo Nakai community forest in North Bengkulu Regency saved as a whole of 1.053 ha saved 287,419.47 tons carbon With 52.77 tons/ha, mixed community plantation forest in Toraja District [16], 72.38 tons ha-1, and urban community forest in Bandar Lampung with an average value of carbon storage of 54.59 tons ha-1, the AGC from this study was significantly greater than agroforestry methods [17]. The total aboveground C-stock in the sacred forest in Pasaman, West Sumatera, was 190.62 tons ha-1.…”

The carbon storage capacity of plantation forests and agroforestry pattern in South Sulawesi in the context of mitigating climate change

“…Undergrowth is one of the components in the forest ecosystem that grows to occupy the lowest strata of the tree and obtain sunlight for its metabolism through the gaps between trees. Undergrowth is a plant that has a diameter of < 3 cm, including seedlings, sprouts, ferns, grasses, climbing plants and mosses [3,6,17]. Hairiah and Rahayu [4] stated that the amount of carbon stored in undergrowth varies between fields, depending on the diversity and density of existing trees.…”

“…From the calculation of carbon potential, it can be seen that the carbon potential of undergrowth is relatively smaller than the potential of carbon storage in trees and litter. This is because the denser the tree canopy, the lower the carbon stock of the undergrowth due to the reduced sunlight reaching the forest floor [3,4,6]. The quality of the growing place affects the development of undergrowth as well as the growth of trees in stands, where stands that have good growing quality will provide better nutrients needed by plants so that the growth of understorey will be better too [7].…”

“…This product provides significant economic returns for the community as a source of community income [2]. Agroforestry pattern also provides a variety of products because it is a mixture of woody tree species, fruit trees, commodity plants and seasonal crops so that it allows the community to obtain multiple benefits, both in the form of building materials, fruit products and commodity crops for economic purposes and annual crops for family consumption [3].…”

“…From a financial standpoint, agroforestry has improved farmers' incomes and product diversity [15]; [16]. From an ecological perspective, the benefit of agroforestry was enhancing soil fertility, land cover, and carbon sequestration and also reducing soil erosion [9]; [17]; [18]; [19], whereas in terms of the social aspect, it can raise farmers' standing by their welfare [20].…”
