Participatory action-research and a framework to evaluate community participation : Sustainability of one-forestry company village <Research Note>

This report addresses the issue of sustainability of one-forestry Company in Batu Majang, a remote village located in the tropical rainforest of east Kalimantan, Indonesia. In the given context, Batu Majang is facing uncertainties regarding the sustainability of forest maintenance in a scenario of discontinuation of a logging company operation in the region. The report is presented in a paper structure and is fundamentally based on secondary data and available references as well as updated information provided by Indonesian specialists during the 2010 summer course of the Graduate School for International Development and Cooperation, Hiroshima University, realized in Bogor, Indonesia. The output of the discussion is a tentative set of insights on sustainable aspects of forestry management defined within a participatory approach framework

The Vegetation Composition and Carbon Stock of Old Shrub Typology to Support the Rehabilitation Program in Sumatra and Kalimantan Islands, Indonesia

The typology of certain old shrubs assists with the selection of suitable plant species for rehabilitation. The carbon stock dynamic in old shrubs is fundamental due to their high uptake during the growth process phase. A plot of 100 m × 100 m (1 hectare) was created in each location, referring to the work of Mueller-Dombois and Ellenberg. The plot was further divided into subsquares measuring 20 m × 20 m; in each plot, there were 25 subplots. Research results showed that the diversity index of old shrubs at the tree, pole, and seedling stage is 2.50–2.66, 1.23–1.50, and 0.67–1.11, respectively. For Kalimantan, the diversity index is lower than that on Sumatra Island, which is 1.64–1.80, 1.00–1.02, and 0.52–0.81, respectively. The carbon stock of the old shrub forest in Sumatra has an average of 36.61 Mg C per ha (standard deviation 14.54 Mg C per ha) to 72.50 Mg C per ha (standard deviation 25.61 Mg C per ha), while Kalimantan has an average of 47.94 Mg C per ha (standard deviation 13.30 Mg C per ha) to 144.07 Mg C per ha (standard deviation 54.64 Mg C per ha). The dynamics of the vegetation composition and carbon stock in each old shrub’s typology are considered when choosing a suitable model, including high carbon stock content, to provide optimal results for rehabilitation activities

Potency, Type, and Quality of Wood Waste Harvesting Timber of Lowland Natural Forest in Two Forest Concessions in South Papua

Papua Province has a natural production forest reaching 13.541 million ha, with log production achieving an average of 8.78% of the total national log production of 5.835 million m3/year. The logs were obtained from selective logging activities using reduced-impact logging techniques. This paper aimed to determine the potency, type, and quality of wood harvesting waste in the two forest concessions lowland natural forests in the province of Papua. The average potential of wood harvesting waste is 4.012 m3/ha or 16.25%. This figure comprises felling waste, which amounts to 2.529 m3/ha or 10.24%, and waste due to skidding and grading scaling, which amounts to 1.483 m3/ha or 6.01%. The types of logging waste consist of stump, end, and base waste with an average volume of 1.014 m3/ha (40.88%), 0.825 m3/ha (30.72%), and 0.690 m3/ha (28.40%), respectively. The quality of logging waste is dominated by defects, with an average of 2.733 m3/ha (69.10%). The waste broken due to the harvesting process averages 0.756 m3/ha (18.84%), while that of good quality averages 0.484 m3/ha (12.07%). The following measures should be taken to mitigate logging waste; (a) company management needs to train on reduced impact logging techniques for both chainsaw and tractor operators, (b) the piece rate system has to be reviewed, and (c) the monitoring function of logging activities in the field has to be improved

Challenges to and Strategies for the Climate Village Program Plus: A Lesson Learned from Indonesia

The Climate Village Program (CVP) is one of the national flagship programs of the Ministry of Environment and Forestry of the Republic of Indonesia to support emission reduction and climate resilience. This paper examines the challenges and strategies for implementing the climate village program in the national and sub-national contexts. Data and information derived from discussions, seminars, focus group discussions, and interviews with local government officials in East Kalimantan were used to analyze the social learning of the CVP plus, including those on the policy process and its concept, integration program, and implementation. Sustainable strategies need to be addressed by integrating the CVP plus into the medium-term development plan of the region. The challenges and way forward of the CVP plus could be an excellent lesson for implementation in all provinces of Indonesia to support FOLU (Forest Other Land Use) Net Sinker 2030 and LTS-LCCR (Long-Term Strategy on Low Carbon and Climate Resilience) 2050. Key challenges and strategies for the CVP plus are highlighted in the planning and implementation phases, especially in improving climate resilience. This study also points out the steps of implementation of the CVP, development partners and their roles in relation to climate change and other socio-economic facts that make it difficult to engage real stakeholders in the implementation of the CVP plus

Mainstreaming Smart Agroforestry for Social Forestry Implementation to Support Sustainable Development Goals in Indonesia: A Review

The increasing need for forest resources and cultivated land requires a solution in forest management to realize sustainable land use. Smart agroforestry (SAF) is a set of agriculture and silviculture knowledge and practices that is aimed at not only increasing profits and resilience for farmers but also improving environmental parameters, including climate change mitigation and adaptation, biodiversity enhancement, and soil and water conservation, while assuring sustainable landscape management. SAF, a solution for land management systems to reduce the rate of deforestation, is a smart effort to overcome the food crisis and mitigate climate change that is prospectively applied mainly in the social forestry area. Optimized forest land utilization could be achieved by implementing SAF and applying silvicultural and crop cultivation techniques to optimize productivity and meet sustainability and adaptability goals. This paper reviews the existing conditions, opportunities, and challenges in the mainstreaming of SAF in social forestry implementation to support the Sustainable Development Goals in Indonesia. Mainstreaming SAF should include policy innovation and regulation implementation, the use of appropriate technology, and compromises or trade-offs among benefits, risks, and resources. SAF is a strategy to revive the rural economy and community prosperity through the optimal use of local resources as well as a form of smart landscape and land-use management that has significant roles in soil and water conservation, bioenergy, climate change responses, and enhanced biodiversity conservation
