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.
Steep slope dry land and unpredictable weather affect the livelihoods of agroforestry farmers in Parigi Subdistrict, mainly through their impact on land productivity, therefore, they have to make choices in livelihood strategies other than agriculture. This research aims (1) to identify the livelihood capitals used by the households of the agroforestry farmers;(2) to analyze the structure and the strategy of livelihood of the households of the agroforestry farmers based on the utility of the livelihood capitals. The research was conducted in Majannang and Manimbahoi villages with a total of 33 samples. The research was carried out using surveys and questionnaires as the instrument of the data collection. The collection of the qualitative data was carried out using the method of in-depth interviews with the informants. The research results indicated that livelihood capitals and utilization by agroforestry farmer consisted of (1) the natural capitals in th e forms of wet field land, dry land, animals, springs and forest areas (2) human capitals in the forms of education and skills (3) social capitals in the forms of land tenure, tree tenure, marketing network and the institution of work relationship (4) the physical capitals in the forms of roads, check dam, markets, solar power plant and production equipment; and (5) the financial capitals in the form of incomes from the farms, off the farms, the non-farms, timber incomes, savings and loans. The income sources which came from on-farm sectors (72.20%), from off-farm (0.61%) and from non-farm (27.8%). The strategy which was done by the households of the agroforestry farmers was various. A household could apply two or more types of livelihood strategies. The calculation result of the livelihood structures indicated that the necessary basis of the agroforestry farmers was the agricultural sectors (72.20%) which implemented eight forms of livelihood strategies
This study aims to determine the management system, composition and income of candlenut-based agroforestry systems in three villages in the Mallawa District. This research was conducted in May - July 2019 in Batu Putih Village, Tellumpanuae Village, Samaenre Village, Mallawa District. The method used is purposive sampling with respondents, namely farmers who have ≥0.1 ha of land area. The number of plots made was 15 plots to determine the volume of wood and the number of respondents interviewed was 30 to determine the form of management. The data that has been collected is processed and analyzed descriptively and quantitatively. The results showed that the management of coffee-based agroforestry systems was initiated by clearing land from grass or shrubs, followed by spacing, then sources of seedlings obtained from government assistance and planting and maintenance which included weeding, pruning, fertilizing and pest control and diseases which then end with harvesting activities. The average for income in the Batu Putih Village of Rp. 24,372,359 -/ha/year, in the Village of Tellumpanue Rp. 27,875,042, -/ha/year, and the Samaenre Village in the amount of Rp. 22,985,365, -/ha/year.
Water has an important role in life. The use of water in various activities must be based on water quality which is influenced by various aspects, one of it is land cover. This study aims to determine water quality, water quality standards and the effect of land cover on water. This study took samples at six points to determine the physical and chemical quality of water. The results showed that the chemical and physical quality of water in the Latuppa watershed still met water quality standards when there was no rain. Parameters that did not meet when rain occurred in the form of turbidity, TSS, and BOD in the river water of the Latuppa watershed. Water quality of the Siguntu Sub-watershed and the Mangkaluku Sub-watershed in the Latuppa River Basin is still relatively good for the use of raw water for drinking water. The water quality in the Latuppa watershed which is covered by forest land (Siguntu Sub-watershed and Mangkaluku Sub-watershed) is better than non-forested (Rantenase Sub-watershed).
