The Air Telang Protected Forest (ATPF) is one of the most dynamic and essential coastal forest landscapes in South Sumatra, Indonesia, because of its location between multiple river outlets, including the Musi catchment—Sumatra’s largest and most dense lowland catchment area. While most ATPF areas are covered by mangroves, these areas have been experiencing severe anthropogenic-driven degradation and conversion. This study aims to evaluate land cover changes and associated carbon emissions in the ATPF over a 35-year period (1985–2020) by utilizing the available Landsat and Sentinel imagery from 1985, 2000, and 2020. Throughout the analysis period, we observed 63% (from 10,886 to 4059 ha) primary and secondary forest loss due to land use change. We identified three primary anthropogenic activities driving these losses, namely, land clearing for plantations and agriculture (3693 ha), coconut plantations (3315 ha), aquaculture (245 ha). We estimated that the largest carbon emissions were caused by coconut plantation conversion, with total carbon emissions of approximately 14.14 Mt CO2-eq. These amounts were almost 4 and 21 times higher than emissions from land clearing and aquaculture, respectively, as substantial soil carbon loss occurs once mangroves get transformed into coconut plantations. While coconut plantation expansion on mangroves could generate significant carbon stock losses and cleared forests become the primary candidate for restoration, our dataset could be useful for future land-based emission reduction policy intervention at a subnational level. Ultimately, our findings have direct implications for current national climate policies, through low carbon development strategies and emission reductions from the land use sector for 2030, as outlined in the Nationally Determined Contributions (NDCs).
Indonesia’s vast forested areas have the potential to serve as a crucial source of livelihood for local communities. However, the current contributions of these forests to community livelihoods are significantly underutilized in comparison to their potential. This study evaluates the financial performance and sustainability of community forest-based businesses operating around the forest management area of the Lakitan-Bukit Cogong forest management unit (LBC FMU). Data were collected through semi-structured and in-depth interviews with the key informants through purposive sampling. Financial viability analysis and a qualitative approach were used to assess the feasibility of the businesses. The findings revealed that all businesses show positive values for all financial indicators. From profit estimation and value-added distribution, all products are shown to be feasible. Concerning the value and supply chain, the rubber-processing industry has a remarkable flow. Moreover, small forest enterprises (SFEs) highlight natural capital optimization through multitudinous derivatives of products that could support a substantial regenerative economy, including citronella essential oil, native honeybees, rubber-based product, biochar, skewers, and liquid smoke. In addition, the multidimensional scaling and rapid appraisal for forest (MDS-RAPForest) approach generates a result based on multiple dimensions (ecology, economics, social and human resources, and institutional and administrative dimensions) showing that overall, SFEs are categorized as sufficient/quite sustainable. Furthermore, mainstreaming adaptable forest-based enterprises, jurisdiction approaches, and cross-production system strategies are also discussed. Our findings suggest that sustainable NTFP-based activities within a community context can be facilitated through interconnected market systems, appropriate price regulations, and support from stakeholders and legal frameworks.
Indonesian forestry challenges in attributional land-use conflicts of overlapping villages and state forests have affected community livelihoods and forest sustainability for decades. This empirical research uncovers the socio-economic attributes of villages in order to gain a better understanding of people−forest relationships in order to guide improved forest management and governance for long-term sustainability. Data were obtained from 69 villages located in the forest management unit of Lakitan Bukit Cogong in South Sumatra Province. Spatially-explicit quantitative measurements and qualitative approaches were employed to explore the interrelationships between human footprint, village development, and conflict resolution strategies over two decades. The results confirmed that utilization of forest areas as part of the village territory (such as for building settlements, public/social infrastructure facilities, plantations and agricultural fields) has long been administered without permits, destabilizing forest functions. Moreover, aspects such as human population size, proximity of villages to the national road and sub-district capital, and the transmigration settlement units have an impact on the Human Footprint Index and Village Development Index. Furthermore, our analyses identified three distinctive forms of conflict based on village type: (1) villages which are administratively included in the forest area; (2) villages for transmigration settlement; and (3) villages adjacent to company management concession areas. In these villages, the clarity of land/forest boundaries and property rights are predominant conflict issues. Several recommendations are proposed to support sustainable forest development; namely, controlling human activities in the forest, improving village management governance, and resolving associated conflicts.
Coffee was a plantation commodity that has quite high economic value among other plantation crops and plays an important role as a source of foreign exchange for the country, however, the pests and diseases that attack coffee plantations in HKM Solok Radjo are not yet known. This research aims to analyze pests and diseases of Arabica coffee (Coffea arabica) in HKm Solok Radjo, Aie Winter, Lembah Gumanti District, Solok Regency, West Sumatra Province. This research uses interview methods and field observations. The data analysis method in this research is descriptive analysis. The results of the research showed that the pests and diseases that were found in the coffee plantations were Hypothenemus hampei (fruit borer), coffee such as leaf rust disease (Hemilleia vastatrix), coffee fruit rot disease (Colletotrichum sp), coffee leaf spot disease (Cercospora coffeicola), upas fungus disease (Upasia salmonicolor). Pests and diseases in this plant are a nuisance because they can cause the plant to be damaged and even die. In handling it, a number of special steps are needed to eliminate pests and diseases in plants, including using pesticides or rotating crops.
Kemunculan pandemi Covid-19 telah merubah pola pergerakan dan kehidupan manusia termasuk dalam interaksi sesama manusia maupun pemanfaatan ruang publik. Covid-19 ditetapkan sebagai pandemi sehingga diperlukan pembatasan fisik dan pembatasan sosial seperti larangan berkumpul massal di kerumunan dan fasilitas umum. RTH menjadi ruang publik bagi warga kota dan menjadi salah satu tempat favorit untuk bersosialisasi, sehingga RTH rawan menjadi lokasi penyebaran Covid-19. Penelitian di beberapa negara maupun kota menunjukkan bahwa kunjungan terhadap RTH cenderung meningkat. Pada RTH (jalur pedestrian) tipe rekreasi di Kota Padang tidak menunjukkan perubahan kunjungan yang signfikan. Penelitian ini bertujuan untuk 1) mengidentifikasi tipe RTH di Kota Padang, dan 2) mengetahui motif warga dalam memanfaatkan atau menggunakan RTH di Kota Padang selama pandemi. Metode penelitian dilaksanakan dengan cara observasi langsung, pengumpulan data melalui kuesioner dan/atau wawancara. Kemudian data-data yang telah dikumpulkan akan dianalisis secara deskriptif. Hasil penelitian menunjukkan bahwa RTH memiliki peranan penting bagi masyrakat walaupun di masa pandemic ini. RTH dimasa pandemic tetap dibutuhkan oleh warga sebagai penyedia udara segar, mengurangi stress, pelarian dari rutinitas sehari-hari, sebagai tempat rekreasi, serta sebagai ruang publik untuk bersosialisasi bagi warga kota.

Changes in land cover are thought to be the main factor in the Urban Heat Island (UHI) phenomenon. UHI is a form of local climate change which is characterized by an increase in temperature reaching 6oC in central urban areas compared to vegetated areas on the outskirts of the city. Compact vegetated land or Green Open Space (GOS), which is able to avoid increasing the surrounding temperature.GOR H. Agus Salim as one of the GOS in Padang City is a place for residents to have recreation and fill their free time by enjoying various culinary delights with friends and family as well as sports activities.This research aims to measure the benefits of tree canopies as climate amelioration in the H. Agus Salim GOR area.The research was conducted in September 2023, with 7 repetitions at 5 measurement points (3 under the tree canopy and 2 in the open field). Data is measured directly in the field with a thermohygrometer. The cooling effect provided by trees was analyzed using a difference approach between measurements in shade and open areas. Thermal comfort level is measured using the empirical formula Temperature Humidity Index (THI).The results showed that there was a decrease in temperature under the tree from 2,0oC (in the morning) to 2,9C (in the afternoon). However, THI calculations show that GOR H. Agus Salim is in the Uncomfortable criteria both under a canopy and in open areas.
