Tropical peat swamp forests that started to experience fires in the 1960s in Sumatra and in the 1980s in Kalimantan are now seriously degraded in many places in Indonesia. But from a longer perspective, we can see the tropical peat swamp forests’ resilience and adaptation. There have been several reports on how deep local knowledge has helped curb further degradation of these forests. Large-scale commercial logging had been undertaken in the Riau area in Sumatra in the 1860s; however, no serious peatland degradation and large-scale fires were reported until the end of the colonial era. Truly serious degradation started only in the middle of the 1980s when large-scale drainage systems were created to support the extensive cultivation of oil palm and timber plantations. Serious fires broke out in 1997, and in 2015 at the time of El Niño. Today only 18.4% of total peatlands in Indonesia are undisturbed natural peatland forests. We also find several initiatives to restore degraded peatl...

COVID-19 severely impacted small industries in Indonesia and many collapsed. Sustainable education is essential to help small industries recover post-pandemic through an open innovation design program to improve small industries’ economic, social, and environmental performance. This paper examined the impacts of the sustainable education program implemented and explored open innovations suitable for the sustainability of small industries in developing countries, such as Indonesia, after the pandemic. This research employed a Participatory Action Research (PAR) approach involving academics, government, the community, and four small industries in West Java, Indonesia. Our findings reveal that the sustainable education program through learning activities and direct practice provides valuable knowledge and experience for small industries in designing economic, social, and environmental innovations. Open innovations post-pandemic suitable for small industries in Indonesia include simple ...

As a developing country, Indonesia is experiencing rapid growth, necessitating the use of development-control instruments to achieve sustainable development. Furthermore, information about land reform implementation in Indonesia can only be found in academic journals written in Indonesian. As a result, determining the appropriate development-control model in Indonesia is critical. The appropriate concepts and development-control tools for Indonesia are discovered by reviewing papers that implement development control globally and the state of development-control implementation locally in Indonesia. However, by presenting the concept of controlling spatial development—beginning with defining development control, then capturing its typologies globally, and finally discussing the implementation condition in Indonesia—the model can also be adopted in countries with a similar planning system. The main gaps and challenges in implementing spatial development-control tools in Indonesia were...

Various factors influence palm oil production, including planting material, environment (climate and soil), and cultivation management. The environment occupies a crucial position that can affect crop production potential even with optimal cultivation management. Unfavorable climatic conditions, for instance, drought, can cause water deficit, which has implications for crop productivity. This paper aims to get a comparative study for the effect of water deficit on the inflorescence period, namely the sex determination phase (29 months before harvesting) and floral abortion (10 months before harvesting). The research was carried out on oil palm plantations on peatland in Riau, Indonesia, with the characteristic annual rainfall of 2000 mm/ year. This study employs a simple regression analysis on panel data of five years and two estates for data analysis. The result highlights that the increase of a 100 mm water deficit on oil palm peatland plantation impacts the decrease in productivi...

El propòsit és mapejar i examinar el desenvolupament d'infraestructura i les instal·lacions sobre el valor de la terra, tant econòmicament com espacialment. L’estudi va utilitzar una anàlisi de línia d’iso-valor per descriure els augments del preu de la terra en dues dècades (2000-2010), models de preus hedònics per determinar com la variable influeix en els augments del preu de la terra i la regressió ponderada geogràficament per descriure l’heterogeneïtat i la dependència espacials. Els resultats van mostrar que la ubicació variable dels terrenys ubicats en habitatges agrupats, la proximitat a l’estació, la proximitat a la terminal d’autobusos i la proximitat a les portes de peatge es van convertir en els factors principals que influeixen en els preus dels terrenys. Aquestes troballes suggereixen que la connectivitat del transport central i perifèric és una consideració en la fixació de preus. La necessitat de transport massiu com a consideració a la selecció d’habitatges en c...

Pemanfaatan lahan gambut dalam kegiatan pertanian, terutama untuk perkebunan menjadi sorotan akhir-akhir ini, akibat terjadinya kebakaran lahan gambut sebagai penyebab bencana asap selama 18 tahun di Indonesia. Tulisan ini bertujuan menguraikan persoalan penggunaan lahan gambut, kejadian kebakaran, dan restorasi lahan gambut dari perspektif sosial ekonomi. Telah dilakukan penelitian dengan pendekatan studi kasus di Desa Tanjung Leban, Kecamatan Bandar Laksamana, Kabupaten Bengkalis, Provinsi Riau. Pengumpulan data dilakukan dengan cara wawancara terstruktur dan mendalam, FGD, dan observasi partisipatif dengan cara tinggal bersama masyarakat. Dari data yang dikumpulkan, dapat dikatakan bahwa persoalan lahan untuk pertanian adalah kompleks, terutama persoalan kepemilikan lahan oleh orang luar Desa. Masyarakat pada umumnya latah melakukan budidaya tanaman sawit, namun sayangnya lahan selalu terbakar secara berulang. Kemudian ada upaya kegiatan restorasi gambut, sebagai usaha pemulihan ...

Peatlands conversion to dryland for plantation has caused environmental havoc and is more prone to natural disasters in Indonesia. Community engagements under village administration should be the main strategy for supporting peatlands restoration. Since the new law on villages was enacted in 2014, the village has gained authority and delegated responsibilities from the upper-level government to make rural development decisions in various sectors, including those connected to environmental management, such as peatland restoration. The recognition of authority is followed by the transfer of significant funds, called village funds, from the central government as a form of commitment to undertake the village law. Currently, applied regulations allow community engagement to utilize the village fund for supporting peatland restoration. This study investigated the community's perceptions of village fund utilization for peatland restoration through in-depth interviews and questionnaires...

Talun-huma is an intensified land use system for swidden agriculture in Indonesia. Talun is a productive fallow system that is meaningful from ecological, social, and economic perspectives. Although it is considered a typical practice in West Java, this study proves that the term talun was used in many places in Indonesia besides West Java during colonial times. This study also shows that talun-huma and agroforestry practice in the surveyed village is closely linked to the socioeconomic structure of the rural society based on the data collected in 2000–1. Huma is more likely to be practiced by the lower strata owning little agricultural and forestry land. The economic development reflected in the growth of banana leaf production and income from the non- agricultural sector income has not excluded or diminished talun-huma and agro forestry practices. Sharecropping practices and agricultural labor relations among the villagers have established huma practice. The social forestry progra...

SUMMARY Although the ecology of tropical peat swamp forests is only now becoming understood, they are already under severe threat of conversion and degradation. Based on studies of the peat swamp forest of the Giam Siak Kecil–Bukit Batu Biosphere Reserve carried out between 2009 and 2010, this paper discusses forest types and regeneration processes in terms of promoting biodiversity conservation and sustainable management of the remaining peat swamp forest. Permanent plots covering a total area of three hectares were established in natural and disturbed forest areas. Within these plots, 135 tree species belonging to 34 families were identified. Mixed peat swamp forest and bintangur forest, which have different dominant species, were identified as the main forest types. The greatest species richness was in logged-over forest, with 82 species and a density of 2,492 stems ha -1 . The success of regeneration varied between typical main species in the logged-over forest and in forest dis...

The Giam Siak Kecil-Bukit Batu Biosphere Reserve was managed by zonation as a approach for multibenefitof management goals. This Bioshere Reserve has a fairly high carbon stock stored in its naturalpeat swamp forest ecosystems. Nevertheless, the condition of the peat swamp forest in the BiosphereGiam Siak Kecil-Bukit Batu currently has been destructed, especially in the buffer and transition zones.The threats of protected areas are not only coming from forest fire factors, but also from encroachmentand illegal logging. Therefore, it requires a recovery effort. This research aims to determine the survivalrate and to estimate the above ground biomass accumulation of the main tree species of peat swamp forestthat used to restore the burnt peat. The estimated total biomass accumulation on the surface was measured using allometric equations. Result of this research proved that Jelutung tree (Dyera polyphylla) has thebest survival rate among the trees (98%), while banana tree (Mezzettia p...

Bayesian analysis is used to perform the probability estimation to examine the Japanese affiliates’ market penetration by exporting from ASEAN4 (i.e. Indonesia, Malaysia, Philippines and Thailand) and China. The estimation is conducted for 13 manufacturing sub-sectors in 2001-2005 and 2006-2010. This study found that Japanese affiliates not only benefited from low cost production and low trade barriers but also seized the advantage of internalized global production network within ASEAN4 and China to export their goods. Production networking could have both favorable and adverse effects on exports of Japanese affiliates.

East Asian, including ASEAN (Association of Southeast Asian Nations), countries have pursued the export-oriented development strategies, attracting foreign direct investment and promoting export-driven growth. However, after the Lehman shock, these countries adopted rebalancing policies from export-driven growth to domestic demand-driven growth. Chinese measures to promote domestic demand since 2008 had succeeded in boosting the economy until 2011 with domestic investments and increase in consumption. Chinese economic growth until 2011–2012 made possible an international commodity boom that resulted in the economic development of Malaysia and Indonesia. However, since 2012, the Chinese economy has been suffering from excess capacity and bad loans, hence ending the international commodity boom. ASEAN countries promptly started rebalancing by cutting back on their reliance on exports and increasing domestic investment and consumption, with variation among the countries. ASEAN countrie...

The peat swamp forest of the Riau Biosphere Reserve has been degraded at an alarming rate. The development of large areas of peatland as timber estates and palm oil plantations has caused a serious threat to the remaining peat swamp forest ecosystems. Forest and land fires have occurred annually, especially in the dry season, and the remaining peat swamp forest is subject to illegal logging activities and natural disturbances. Villagers continuously convert the remaining natural peat swamp forest into jungle rubber gardens and oil palm plantations. Four objectives of the study: (1) to clarify the current condition and ecological characteristics of the remaining peat swamp forest ecosystems, (2) reestablishing typical canopy tree species and restoring degraded peat swamp forest and peatland areas, (3) to determine a mechanism or directions for the participation of the local population; and, (4) to discuss a model for the promotion of sustainable management of peat swamp forest ecosystems in the biosphere reserve. The improvement of management of remaining peat swamp forests and rehabilitation should consider the unique ecological characteristics particularly the dominant tree species, fast growing species as well as the peat characteristics. The remaining peat swamp forests should be kept in their natural conditions in order to provide continuous ecosystem services, given their unique biodiversity characteristics, protection could be enhanced by adding incentives to local communities including monetary incentives from biodiversity and climate change mitigation funds. The promotion of a sustainable management model should be the direction of actions to conserve the remaining natural forests, regenerate and restore the degraded peat swamp forests, and create economic incentives enabling sustainability for the local community.
