The adoption of agroforestry system aims to combine food production enhancement to compensate population growth with the improvement of agricultural marketable products to increase household income. The diversification of food crop products requires more effective land use. In Gunungkidul, high-density teak (Tectona grandis) plantation has dominated many private forests. The area under the tree crown has received low light intensity, where only shade-resistant plants can survive. Tuber crops, i.e., arrowroot (Maranta arundinacea), canna (Canna edulis) and yam (Dioscorea esculenta) are shade-tolerant crops, which were planted in tree understory for supplementary food production and income generation. The cultivation under teak stand has been overlooked due to uncertainty in tuber productivity. To address this knowledge gap, the effect of teak shade (5- and 7-year teak) on the growth and yield of the three tuber crops was examined. The results indicated that both teak trial areas (with RLI 45.13% and 38.76%) were suitable for canna production (LER > 1), while management options were recommended for enhancing arrowroot and yam production. The LER of intercropped three-tuber crops under 5 years’ teak were >1, while of those under 7 years’ teak, only canna reached >1. Canna is the preferred option to be mixed in teak agroforestry systems with low light intensity due to its consistent yields, whether planted in open area or under teak shade. Silvicultural management, pruning and thinning are recommended to increase the growing space and resource sharing for intercropped plants. Land optimization in private forest understory using shade-resistant tubers will offer medium-term benefits, provided that proper silvicultural procedures are applied.
A strategy that has the potential to contribute to the achievement of the targets established under SDG 8 (“Decent Work and Economic Growth”) involves the development of sustainable tourism to create productive job and livelihood opportunities and to promote local culture and products. In the province of East Nusa Tenggara (NTT), Indonesia, ikat weaving is an integral part of the cultural heritage of the region, with ikat characterized by unique design motives and the use of natural dyes. Unfortunately, in some areas, the use of natural dyes is diminishing as a result of competition with synthetic dyes and the limited availability of raw materials, particularly for the production of blue dye. The development of Indigofera spp. to produce natural, plant-based blue dye has significant potential to contribute to community incomes and employment. This study outlines a strategy for developing the use of Indigofera spp. as a natural dye and describes its potential for contributing to community incomes, especially on Timor Island, NTT. The study shows that weavers currently use indigo plants that grow naturally in gardens and yards. Although the community has a tradition of using these plants, informed by local wisdom, to develop the cultivation and processing of this plant through the application of the appropriate techniques, including innovative approaches to producing indigo paste, could enable the development of Indigofera spp. cultivation on a larger scale. The study shows that the availability of suitable land is high (±370 thousand ha), with 80% of the suitable land being categorized as critical. The study proposes a development based on the analysis of strengths, weaknesses, opportunities, and threats to assess the manner in which these opportunities could be leveraged with the support and participation of local communities and other stakeholders by leveraging the culture and wisdom of the community regarding the use of Indigofera spp.
The COVID-19 pandemic has affected the household bamboo handicraft industry in rural areas. A comprehensive study was conducted to identify impacts, living strategies, and economic recovery; the findings will be used as a basis to recommend supporting policy to create a more resilient bamboo handicraft business. This study applied phenomenological approach to interpret the social impacts of the COVID-19 pandemic. In December 2021, 30 bamboo craftsmen in Semin Village, Gunungkidul, Yogyakarta Special Province were interviewed. Results show that 96.7% of bamboo craftsmen experienced a decrease in profit, with 46.6% reporting no order for a long period. The profit earned by craftsmen decreased by 76.50%. Bamboo craftsmen adapted to the COVID-19 pandemic by minimizing capital expenses, creating innovations marketing in options (i.e., direct sales, selling online) and focusing on alternative income sources (farming, hunting and gathering, selling food, and becoming laborers) to survive. As the spread of the virus was controlled, leading to the relaxation of restrictions on economic activities, the bamboo industry in Semin has entered an economic recovery phase. Currently, the average profit has reached 66.18%, compared to the profit earned in normal pre-pandemic situation. We believe the government should facilitate craftsmen to build their capacity in e-commerce, export mechanism, market network creation, tool acquisition, and English proficiency. This would enhance the bamboo handicraft industry in Semin to be more resilient facing future challenges
Community forest management for timber production requires short- and long-rotation companion species to fulfill the demands of the timber industry, improve farmer welfare and maintain environmental sustainability. Four species (Falcataria moluccana, Neolamarckia cadamba, Acacia mangium and Gmelina arborea) were tested as short-rotation timber crop companion species for teak (Tectona grandis) on dry-rocky soil in the Gunungkidul community forest. The selection of short-rotation timber species was based on growth performance and survival rate at the teak site. Two years after planting, the viability of G. arborea (87.3%) and A. mangium (78.2%) was significantly (p < 0.05) higher than that of N. cadamba (40.6%) and F. moluccana (18.0%). G. arborea and N. cadamba achieved the best growth in terms of height, diameter, basal area, and volume, with the growth of A. mangium and F. moluccana being significantly inferior. Gmelina arborea has the ability to adapt to teak sites, grow well, and accompany teak. Neolamarckia cadamba demonstrated good growth with potential as a teak companion, and it demonstrated limited drought tolerance on the dry-rocky soils of the study sites. Acacia mangium had a high survival but produced slow growth, indicating that it required an advance evaluation in future years. Falcataria moluccana has different growing site requirements to teak so the performance was relatively poor at the study site. This mixed pattern provides benefits to farmers through commercial thinning of short rotations species, 5–8 years post establishment. Thinning operations will also increase the productivity of residual teak stands. The diversification of timber species in community forests can provide earlier returns, enabling the adoption of silviculture management by smallholders and communities.

Sumatra’s lowland tropical rainforest is in the third place after Kalimantan and Papua in terms of Indonesia’s plant species diversity. Shorea macroptera is one of the species from the Dipterocarpaceae family, known as an important commercial timber tree species. In September 2019, the study was conducted in Rantau Bertuah Forest, Siak Regency, Riau Province, Sumatra, with a total sample plot area of 1 ha. The data were analyzed to show the vegetation quantitative structure and composition on the study site using the Important Value Index, and the association of S. macroptera using the Ochiai index. The results recorded 55 plant species belong to 33 families on this study site. Dipterocarpaceae, Euphorbiaceae, and Fabaceae have the most abundant species, encompassed 51 species ≥10 cm in diameter with a total of 624 individuals. The result showed that the top three dominant species in this area, namely Callophyllum macrocarpum Hook.f. (IVI = 27.88%), Shorea parvifolia Dyer (IVI = 21.98%) and Gironniera nervosa Planch. (IVI = 19.99%). C. macrocarpum dominated all the regeneration levels: tree, sapling and seedling with IVI of 27.88%, 49.57% and 86.31%, respectively. S. macroptera has the strongest association with C. macrocarpum (Ochiai index of 0.73), followed by the S. parvifolia (Ochiai index of 0.61) and G. nervosa species (Ochiai index of 0.51). S. macroptera is widely used for industrial timber purposes and has limited distribution. Therefore, it is necessary to increase the efforts to manage it sustainably, especially in production forests.
