Abstract: 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 ersification 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 , while of those under 7 years’ teak, only canna reached . 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.

Abstract: 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

Abstract: Sengon ( Falcataria mollucana ) has rapid growth, but susceptible to pest and disease, while manglid ( Magnolia ch aca ) has slower growth compared to sengon , but relatively more resistant. Farmers can prevent high losses by interplanting their land with sengon and manglid. This interplanting technique between sengon and manglid has not been widely known. The study was conducted in Sodonghilir Village, Tasikmalaya, West Java, from December 2015 - November 2018. Seedlings were planted with minimal height of 30 cm and planted at the beginning of the rainy season, and each seedling was tied to a bamboo stick. One month after planting, plants were given an organic fertilizer TSP (phosphorus) and urea with a ratio of 1:2, 50 gr each plant. The study used split plots design with tree species ( sengon and manglid ) as the main factor and spacing as sub-plots (3 x 3 m, 3 x 4 m, 3 x 5 m, and 3 x 6 m). The treatments resulted in 8 combinations with 49 plants as the observation unit with four replications. The total planted area was 1 ha. The results showed that the interaction between species and spacing had a significant effect on the growth of sengon and manglid . The results showed the highest height was shown by treatment S4 ( sengon , 3 x 6 m) with a height of 297.48 cm, while the highest diameter by S3 ( sengon , 3 x 5 m) with a diameter of 52.9 mm. Sengon is more productive than manglid . However, the local community prefers to plant both species ( manglid and sengon ) to overcome the loss of income because sengon is more prone to pest and disease compared to manglid .

Abstract: Agroforestry has been practiced for decades and is undoubtedly an important source of income for Indonesian households living near forests. However, there are still many cases of poverty among farmers due to a lack of ability to adopt advanced technology. This literature review aims to identify the characteristics and factors causing the occurrence of agricultural subsistence and analyze its implications for the level of farmer welfare and the regional forestry industry. The literature analysis conducted reveals that small land tenure, low literacy rates, and lack of forest maintenance are the main causes of the subsistence of small agroforestry farmers. Another reason is that subsistence-oriented agroforestry practices are considered a strong form of smallholder resilience. All of these limitations have implications for low land productivity and high-sawn timber waste from community forests. To reduce the subsistence level of farmers, government intervention is needed, especially in providing managerial assistance packages, capital assistance, and the marketing of forest products. Various agroforestry technologies are available but have not been implemented consistently by farmers. Therefore, it is necessary to develop an integrated collaboration between researchers, farmers, and regionally owned enterprises (BUMD) to increase access to technology and markets. Although it is still difficult to realize, forest services, such as upstream–downstream compensation and carbon capture, have the potential to increase farmer income.

Abstract: 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 ersification of timber species in community forests can provide earlier returns, enabling the adoption of silviculture management by smallholders and communities.

Abstract: The government’s efforts in maintaining the food security includes developing alternative food sources, developing local food crops and improving the use of dry land for food crops cultivation. Planting tubers are common in private forest lands, such as in Semin Village, where arrowroot ( Maranta arundinacea L.) can live under teak ( Tectona grandis L.) stands. Based on this, a trial was conducted on planting three species of tubers, namely arrowroot/garut, canna/ganyong ( Canna discolor Lindl.), and yam/gembili ( Dioscorea esculenta (Lour.) Burk.) under teak stands. In mixed cropping patterns, there are limitations in obtaining light and nutrient sources for the plants underneath. Therefore, this study aimed to determine the morphological adaptation of three species of tubers, especially under the shade of teak, at different ages. The research design was completely randomized (CRD), while data analysis used two-way Anova. The results showed that the difference in relative light intensity (RLI) at eight weeks after planting had a significant effect on the height, the number of shoots or stems, and the number of leaves of the tested tubers. The size of the plant and the diameter of the stem showed the highest average under the shade of seven years teak stand, the contrary, the highest number of shoots or stems found in the open areas.

Abstract: Private forest farmers in Semin Village, Semin District, Gunung Kidul Regency transformed the cropping patterns from monoculture to polyculture to meet increasing needs. The farmers planted a variety of food crops to fulfill their short and medium-term needs, and woody plants to meet the long-term needs. Beside this, farmers have processed arrowroot tubers into flour, which can increase household income. The tuber plants apart from being able to live under the shade, have a low glycemic index value so they can be consumed by the diabetics. The method used randomized block design, trials were conducted by cultivating 3 species of tuber plants under the teak shade. Species of tuber plants were arrowroot, canna and yam. The treatments given were: 1) without shade, 2) under 5-year-old teak, 3) under 7-year-old teak. The aim was to understand the relationship between tuber plant growth variables and their environments. Tuber plant growth variables were height and diameter of plant, number of leaves and number of shoot. Environment variables were height and diameter of the teak trees, soil characteristic, and micro climate condition. The relationship was analyzed using linear regression. The results of regression analysis showed that there was a relationship between soil characteristics and plant height (R 2 =100%), stand height and number of leaves (R 2 =25.50%), air temperature and number of shoots (R 2 =22.60%), humidity and the number of shoots (R 2 =16.70%), light intensity and the number of shoots (R 2 =14.80%), as well as temperature, humidity, light intensity, percent canopy cover simultaneously and tuber weight/clump (R 2 =39.10%).

Abstract: Limited agricultural land areas combined with increasing demands for food require breakthroughs in land use development using agroforestry systems. Intercropping root crops with trees could be an alternative for food production in forest areas. This study aimed to assess the feasibility of cocoyam (Xanthosoma sagittifolium (L.) Schott) farming on dry land within 12- and 42-year-old teak (Tectona grandis L.f.) forests to support local food security. The feasibility assessment took into account both productivity and socio-economic aspects. The agroforestry land productivity was measured using the land equivalent ratio (LER), and our analysis of the cocoyam farming within the teak stands was carried out using the revenue/cost ratio (R/C) at the demonstration plot scale. Furthermore, we also surveyed farmers’ perceptions of the production of cocoyam for food security. The results showed that the R/C values of cocoyam tuber production in agroforestry systems were lower than 1. However, the production rates of cocoyam tubers in the 12-year-old teak stand (48.3% light intensity) and the 42-year-old teak stand (62.5% light intensity) were 2.64 and 2.76 tons/ha, respectively. The overall yields from the teak and cocoyam agroforestry systems were more profitable than those of the monoculture system, as indicated by the LER values of 1.61 and 1.85. Cocoyam production was socially acceptable (77% of respondents) as a smallholder subsistence agroforestry practice to meet food demand. Increasing cocoyam productivity in teak forests requires the adoption of agroforestry silvicultural technology to achieve food security for rural communities. To increase their farming production and income, farmers could apply intensive silvicultural practices. Governmental support that could be provided includes encouraging product ersification and providing assistance for the processing and marketing of cocoyam products.

Abstract: Agroforestry in dry-land is an effort to increase land productivity and to support food security program. Practicing the proper agroforestry in the early age is very essential not only to optimize the annual crop yield but also giving benefit to the tree growth. Ganitri (Elaeocarpus ganitrus Roxb.) is a tree species that produce beads with high economic value for religious purpose in Southeast Asia and India. Meanwhile, maize is one of staple food throughout Southeast Asia which support food security program. This research aimed to discover the suitable maize variety and planting pattern for early agroforestry in order to get optimum yield and able to support ganitri growth as the main tree. Randomized block design with split plot design was conducted with 2 factors and 3 replications. The main plot was maize variety (single cob and double cobs) and the sub-plot was the planting pattern (two rows and three rows of maize in ganitri alleys). The hypothesis of this research was maize varieties and planting pattern in ganitri based agroforestry had influence on maize production and the growth of ganitri. The result shows that interaction between maize variety and planting pattern have significant effect on the average height of maize in the early and end of growth, nevertheless it does not give any significant response on the early growth of ganitri except for the branch number. The utilization of double cobs variety with three rows of maize in between trees gave higher yield, 4.55 t ha −1 dry kernels in total. This planting pattern has the potency to be applied in order to optimize the land-use on early ganitri -based agroforestry in dry land.

Abstract: Massive import of garlic products has caused a declining interest of Indonesian farmers to plant garlic due to losing competition in clove size and lower selling price. This has discouraged the farmers from applying the innovation of garlic farming technology that caused low garlic productivity in Indonesia (8.7 t/ha). The purpose of this research was to improve the technology package of garlic cultivation at the farmer level. The study was conducted from July to October 2021 in Cianjur Regency, West Java, Indonesia. The technology packages experimental design was randomized block design with nine replications. The technology packages tested were farmer’s technology package, introduced technology package-1, and introduced technology package-2. The components of the technology package tested were cultivar, mulch types, number of cloves per hole, biofertilizer, biopesticide, and chemical fertilizers. The observed variables were plant growth, bulb yield, and input-output of farming. The results showed that the technology package introduction could increase the plant performance, namely the plant height, stem diameter, bulb fresh weight and bulb diameter. The highest R/C ratio was reached by the technology package introduction-1 (1.47). The introduced technology package-1 was more profitable than package-2 as indicated by the MBCR value of 12.46 and 8.83 respectively.

Abstract: Indonesia is the largest archipelagic country in the world, with 17,000 islands of varying sizes and elevations, from lowlands to very high mountains, stretching more than 5000 km eastward from Sabang in Aceh to Merauke in Papua. Although occupying only 1.3% of the world’s land area, Indonesia possesses the third-largest rainforest and the second-highest level of bio ersity, with very high species ersity and endemism. However, during the last two decades, Indonesia has been known as a country with a high level of deforestation, a producer of smoke from burning forests and land, and a producer of carbon emissions. The aim of this paper is to review the environmental history and the long process of Indonesian forest management towards achieving environmental sustainability and community welfare. To do this, we analyze the milestones of Indonesian forest management history, present and future challenges, and provide strategic recommendations toward a viable Sustainable Forest Management (SFM) system. Our review showed that the history of forestry management in Indonesia has evolved through a long process, especially related to contestation over the control of natural resources and supporting policies and regulations. During the process, many efforts have been applied to reduce the deforestation rate, such as a moratorium on permitting primary natural forest and peat land, land rehabilitation and soil conservation, environmental protection, and other significant regulations. Therefore, these efforts should be maintained and improved continuously in the future due to their significant positive impacts on a variety of forest areas toward the achievement of viable SFM. Finally, we conclude that the Indonesian government has struggled to formulate sustainable forest management policies that balance economic, ecological, and social needs, among others, through developing and implementing social forestry instruments, developing and implementing human resource capacity, increasing community literacy, strengthening forest governance by eliminating ambiguity and overlapping regulations, simplification of bureaucracy, revitalization of traditional wisdom, and fair law enforcement.
