“…In general, the private forests that were utilized as research location were not managed intensively [30]. The private forests received no fertilization for teak [52], no weeding [45], no pruning and were rainfed [45,52]. Thinning meant harvesting big trees [53], and the tree selection was cut down when farmers experienced financial hardship [53,54].…”

“…There is a tendency that optimizing the light will boost plant growth, but not tuber productivity. Yam's growth and production will give better results in open areas, although it still produces quite good growth in 30-50% shade (RLI 50-70%) (Table 5) [52]. In heavy shade (75% or RLI 25%), yam is not adaptable, which is indicated by the production of fewer stolons and tubers [67].…”

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.

“…HTR is an option to revitalize the forestry industry to increase the availability of round-wood materials for the forestry industry (Alviya et al, 2020). However, the Social Forestry Program and HTR development performances are still relatively slow (Wiyono et al, 2018;Wulandari et al, 2017).…”

Indonesia has abundant forest resources, reaching 120 million hectares of forest area. However, the forestry sector's contribution to the national economy continues to decline. The low performance of the forestry sector cannot be separated from the limited availability of round-wood materials for its processing industries and insufficient development of the multi-businesses activities among the forestry companies. Therefore, increasing the forestry sector's productivity is necessary through raising investment. This study investigates the impacts of investment in the forestry sector on Indonesian economic performance, including output, income, employment, and import, using the Input-Output (I-O) Model. The results show that investment in the forestry sector will increase output, income, and labour in the forestry sector and its related sectors. However, with the increase in its output, the demand for inputs, including round-wood materials, will also increase, encouraging a rise in imports. Thus, an increase in investment in the forestry sector needs to be balanced with the availability of roundwood materials and other associated inputs in Indonesia. For the follow-up research, it is important to separate the investment into upstream and downstream activities along the forestry value chain and include a regional aspect in the analysis.

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.
