Abstract

Agroforestry systems are an innovative approach to land management that harmoniously integrates trees or forests with agricultural crops and livestock, creating a mutually supportive ecosystem. This approach not only increases land productivity but also contributes significantly to global food security, especially amid the challenges of climate change and environmental degradation. In addition, agroforestry plays an important role in biodiversity conservation by preserving natural habitats and preventing soil erosion, while providing economic benefits to farmers through crop diversification. Indonesia, as one of the world's megabiodiversity countries, has a wealth of local species, including various types of tropical trees, medicinal plants, and traditional food sources that have been integrated into agroforestry practices since ancient times. Species such as durian, petai, and various types of hardwood have become an integral part of local agricultural systems, which not only support ecological sustainability but also the culture of indigenous peoples. However, despite this great potential, knowledge about the use of local species in agroforestry in Indonesia is still limited, with many gaps in research that need to be identified to encourage more effective development. This study aims to map research trends, key study focuses, frequently used key species, and knowledge gaps related to the integration of local species in agroforestry systems in Indonesia. By conducting this mapping, this study is expected to reveal the temporal and geographical patterns of agroforestry research, identify under-explored endemic species, and highlight areas such as Java, Sumatra, and Kalimantan that have high potential but have not been fully researched. The SMS method applied involved a systematic and structured search of various leading scientific databases, such as Scopus, Web of Science, and Google Scholar, using specific keywords such as “agroforestry Indonesia,” “local species,” and “biodiversity conservation.” This process was followed by rigorous screening based on inclusion-exclusion criteria, which included publications in English and Indonesian from 2000 to the present, as well as a focus on relevant empirical studies or reviews. Data extraction was then conducted for quantitative analysis, such as publication frequency per year and geographical distribution, as well as qualitative analysis to identify key themes and knowledge gaps, such as the lack of studies on the impact of agroforestry on climate change or integration with modern technology. The mapping results from this study are expected to provide strategic guidance for researchers, policymakers, and agroforestry practitioners. These findings can encourage the development of more sustainable programs, such as the promotion of local species in organic certification schemes or the integration of agroforestry into national policies such as the National Biodiversity Action Plan. In addition, these results will help address knowledge gaps, such as the need for further research on the adaptation of local species to the threats of deforestation and urbanization, so that agroforestry can become an effective solution for food security and conservation in Indonesia.

Abstract

Nature-based solutions (NBS) represent a paradigm shift in water resources management, leveraging ecosystem functions to address hydrological challenges while delivering co-benefits for biodiversity and human well-being. The objectives of this article are: (1) to elucidate the conceptual foundations and terminology of natural reservoir as NBS water storage system; (2) to describe the benefits and  functional mechanisms; and (3) to describe the implementation of natural reservoirs utilization. This systematic literature review examines water retention infrastructure functioning as natural reservoirs within the NBS framework, including constructed wetlands, retention ponds, floodplain restoration, and beaver dam analogues. Following PRISMA guidelines, we analyzed peer-reviewed publications (2014–2024) with DOI identifiers from Scopus-indexed journals to elucidate conceptual foundations, functional mechanisms, and implementation techniques. Results demonstrate that NBS water storage systems provide multifunctional benefits: flood peak attenuation (15–30% runoff reduction), groundwater recharge enhancement, water quality improvement through biogeochemical processes, and habitat creation. European implementations dominate the literature (68% of studies), particularly in Germany, Czech Republic, and Slovakia where landscape-based water retention measures have been integrated into river basin management. Notable implementations include the Püspökszilágy NWRM project (Hungary) eliminating flash floods while stabilizing groundwater, and extensive constructed wetland networks in China treating wastewater while providing 103.3 mm soil storage capacity in urban areas. Critical success factors include site-specific hydrological assessment, native vegetation selection, and adaptive management protocols. Challenges persist regarding long-term sedimentation management, climate resilience under extreme events, and standardized monitoring frameworks. This review establishes that natural reservoir as one of NBS water storage systems, when properly designed, deliver superior ecosystem service bundles compared to conventional gray infrastructure while enhancing landscape connectivity and climate adaptation capacity.

Abstract

Getah pinus (Pinus merkusii) merupakan Hasil Hutan Bukan Kayu (HHBK) yang memiliki nilai ekonomi tinggi dan berperan penting dalam menciptakan pengelolaan hutan berkelanjutan. Kelompok Tani Hutan (KTH) Sipatuo di Desa Pa'tengko, Tana Toraja, terlibat aktif dalam penyadapan getah pinus melalui skema Perhutanan Sosial, yang tidak hanya berdampak pada ekonomi tetapi juga pada kelestarian hutan. Penelitian ini bertujuan untuk mengidentifikasi dan menganalisis teknik pengelolaan penyadapan getah pinus serta dampak sosial-ekonomi yang ditimbulkan bagi anggota KTH Sipatuo. Penelitian menggunakan pendekatan kualitatif deskriptif dengan metode pengumpulan data melalui observasi lapangan, wawancara mendalam dengan anggota KTH, dan studi dokumentasi. Data dianalisis secara tematik untuk mengelompokkan informasi terkait teknik sadap, rantai nilai getah pinus, dan dampaknya. KTH Sipatuo menggunakan teknik koakan (quare) dengan pembaruan luka setiap dua minggu. Getah dikumpulkan setiap 15 hari dan dijual ke mitra (CV. Pindo Indonesia) dengan harga Rp8.000 per kg. Rata-rata produksi per karung antara 70–97 kg. Dampak sosial-ekonomi yang signifikan meliputi peningkatan pendapatan rumah tangga, penciptaan lapangan kerja, penguatan kelembagaan kelompok tani, dan peningkatan kesadaran konservasi. Pengelolaan getah pinus oleh KTH Sipatuo telah memberikan kontribusi nyata terhadap perekonomian lokal sekaligus mendorong pelestarian hutan. Namun, diperlukan pengembangan diversifikasi tanaman dan peningkatan kapasitas pengolahan untuk meningkatkan nilai tambah dan keberlanjutan jangka panjang.

Abstract

Forest and Land Rehabilitation (RHL) is an effort to restore the functions of degraded forests and lands through vegetative activities, one of which is tree planting. Teak (Tectona grandis) is one of the plant species with the potential to be used in RHL activities because it has high economic value, broad adaptability, and a root system capable of helping improve land conditions. This study aims to examine teak nursery techniques as well as teak planting techniques in RHL activities as an effort to support the success of land rehabilitation both ecologically and economically. This study used a descriptive qualitative method with a literature study approach supported by field experience and interviews. Secondary data were obtained from scientific journals, books, and relevant articles through Google scholar searches using the keywords teak nursery, teak nursery techniques, forest and land rehabilitation, and benefits of teak. Primary data were obtained through interviews with employees related to nursery activities, teak seedling production, and the implementation of RHL. The data were analyzed descriptively and qualitatively through the processes of selection, classification, comparison, and interpretation of information. The results of the study indicate that the success of teak utilization in RHL activities is influenced by seedling quality and proper planting techniques. Teak nursery techniques include seed treatment through scarification, sowing, pricking out, seedling  maintenance, and seedlings ready for planting at the age of approximately 3-6 months. Meanwhile, planting techniques include determining the planting location and seedling type, planting at the beginning of the rainy season, arranging planting spacing from 3 x 3 meters to 5 x 5 meters, and plant maintenance through replanting, weeding, and fertilization. With proper nursery and planting techniques, teak has the potential to support the success of RHL both ecologically and economically.

Abstract

The Sario Sub-Watershed is a densely populated urban catchment in Manado City, North Sulawesi, that drains directly into Manado Bay and is prone to recurring floods and riverbed siltation. This study analyzed the rate of soil erosion and the amount of sediment reaching the Sario River in the downstream part of the sub-watershed, an area not yet specifically assessed by earlier studies covering the whole Sario watershed. Erosion was estimated using the Universal Soil Loss Equation (USLE) integrated with a Geographic Information System (GIS), combining rainfall erosivity (R), soil erodibility (K), slope length and steepness (LS), land cover (C), and conservation practice (P) factors derived from ten years (2015-2024) of rainfall data, soil and land-cover maps, and a Digital Elevation Model. The resulting sediment yield delivered to the river was then estimated using the Sediment Delivery Ratio (SDR) of Auerswald (1992) and the Boyce method. Results show a total annual erosion of 715,436.74 tons across 1,207.10 ha, or an area-weighted average of 592.69 tons/ha/year, placing the sub-watershed in Erosion Hazard Class V (very severe) under Indonesian Ministry of Forestry Regulation No. 32/2009. Class V areas cover 596.96 ha (49.45%), concentrated on steep, densely settled terrain dominated by Eutric Cambisol soil. The estimated SDR of 0.291 yields a sediment load of 208,191.90 tons/year reaching the Sario River. These findings indicate that erosion and sedimentation in the sub-watershed are driven mainly by steep topography combined with low-conservation-value settlement land, underlining the need for forestry-based watershed interventions such as land rehabilitation, urban green open space development, riparian buffer strips, and agroforestry to reduce erosion, sedimentation, and recurrent flooding.
