South East Asia is widely regarded as a centre of threatened biodiversity owing to extensive logging and forest conversion to agriculture. In particular, forests degraded by repeated rounds of intensive logging are viewed as having little conservation value and are afforded meagre protection from conversion to oil palm. Here, we determine the biological value of such heavily degraded forests by comparing leaf-litter ant communities in unlogged (natural) and twice-logged forests in Sabah, Borneo. We accounted for impacts of logging on habitat heterogeneity by comparing species richness and composition at four nested spatial scales, and examining how species richness was partitioned across the landscape in each habitat. We found that twice-logged forest had fewer species occurrences, lower species richness at small spatial scales and altered species composition compared with natural forests. However, over 80 per cent of species found in unlogged forest were detected within twice-logged forest. Moreover, greater species turnover among sites in twice-logged forest resulted in identical species richness between habitats at the largest spatial scale. While two intensive logging cycles have negative impacts on ant communities, these degraded forests clearly provide important habitat for numerous species and preventing their conversion to oil palm and other crops should be a conservation priority.

Research Highlights: Our findings highlight that the contribution of carbon sequestration from plantations to REDD+ will remain limited, and that opportunity costs in Southeast Asia will likely increase, due to future oil palm expansion. Background and Objectives: Land use, land-use change, and forestry (LULUCF) are significant sources of carbon emissions. The United Nations Framework Convention on Climate Change (UNFCCC) agreed that the Reducing Emissions from Deforestation and Forest Degradation Plus program, also known as REDD+, could contribute to carbon sinks in tropical regions. These reductions could serve as carbon credits that offset emissions from other sources. Materials and Methods: This study uses the cellular automaton technique to simulate the business-as-usual (BAU) scenario and the gain-loss method, to measure carbon emissions resulting from forest conversion. The output of the integration of the models makes it possible to evaluate one of the most important financial costs: opportunity costs. Two scenarios (with and without consideration of carbon sequestration) in rubber and oil palm plantations are examined. Results: A sensitivity assessment in Kalimantan, Indonesia, shows that carbon sequestration from plantations affects value of opportunity costs less than social discount rates. Further analysis suggests that oil palm plantations have a greater impact than rubber plantations. Conclusions: Our study provides a case that can be applied to other regions for evaluating the impacts of plantation carbon sequestration, and insights that can help local policymakers design a financially attractive REDD+ program in other forest areas of the world.

ABSTRACTTropical forests are being rapidly altered by logging and cleared for agriculture. Understanding the effects of these land use changes on soil bacteria, which constitute a large proportion of total biodiversity and perform important ecosystem functions, is a major conservation frontier. Here we studied the effects of logging history and forest conversion to oil palm plantations in Sabah, Borneo, on the soil bacterial community. We used paired-end Illumina sequencing of the 16S rRNA gene, V3 region, to compare the bacterial communities in primary, once-logged, and twice-logged forest and land converted to oil palm plantations. Bacteria were grouped into operational taxonomic units (OTUs) at the 97% similarity level, and OTU richness and local-scale α-diversity showed no difference between the various forest types and oil palm plantations. Focusing on the turnover of bacteria across space, true β-diversity was higher in oil palm plantation soil than in forest soil, whereas community dissimilarity-based metrics of β-diversity were only marginally different between habitats, suggesting that at large scales, oil palm plantation soil could have higher overall γ-diversity than forest soil, driven by a slightly more heterogeneous community across space. Clearance of primary and logged forest for oil palm plantations did, however, significantly impact the composition of soil bacterial communities, reflecting in part the loss of some forest bacteria, whereas primary and logged forests did not differ in composition. Overall, our results suggest that the soil bacteria of tropical forest are to some extent resilient or resistant to logging but that the impacts of forest conversion to oil palm plantations are more severe.

The island of Kalimantan is one of the islands that has a vast forest. Kalimantan Island is also the most important island for Indonesia, even the world. Parenggean is one of the sub-districts located in Kotawaringin Timur Regency, Central Kalimantan Province. Parenggean sub-district with an area of 493.15 km² is one of the sub-districts in East Kotawaringin Regency which has a very large oil palm plantation. This study will present data on the amount of forest land cover that has been converted. To get extensive forest conversion, this research uses the Remote Sensing and Geographic Information Systems approach. The result of research this proves there have been over the function forests became oil palm plantation in Parenggean District. The area of ​​forest that was converted into oil palm plantation in the research area is 5,143.15 hectares in 1990-2000 and 17,560.45 hectares in 2000-2010.

Spatial Plan

AbstractLaw No. 26 Year 2007 on Spatial Planning (UUPR) mandated that all levels of government administration, ranging from the national, provincial, district/ city are obligated to prepare Spatial Plan (RTR). Until 2012, Central Kalimantan is one of the provinces which have not completed its Spatial Plan; one of the reasons was the lack of spatial integration of forestry spatial planning and provincial spatial planning of Central Kalimantan.The absence of spatial integration of forestry and provincial spatial planning of Central Kalimantan has the implication in triggering conflicts of land use. Forest areas were converted into oil palm plantations without any official procedures. There are 282 units of oil palm companies, occupying 3.9 millions hectares of forest area, with non-procedural procedures to convert forest area into oil palm plantation.To resolve this problem, the Government has revised the regulation of forest conversion by issuing PP No. 60/2012, provides opportunities for oil palm plantations, which under the Law of Forestry located in forest area but based on RTRWP of Central Kalimantan lies on APL or cultivation area, given the opportunity to re-apply the permit/license.  IntisariUndang- Undang No. 26 Tahun 2007 tentang Penataan Ruang (UUPR) mengamanatkan bahwa semua tingkatan administrasi pemerintahan, mulai dari nasional, provinsi, kabupaten/kota diwajibkan menyusun Rencana Tata Ruang (RTR). Kalimantan Tengah sampai dengan tahun 2012 merupakan salah satu Provinsi yang belum menyelesaikan Tata Ruang, salah satu penyebabnya karena belum adanya padu serasi antara tata ruang kehutanan dengan tata ruang Provinsi Kalimantan Tengah.Implikasi dari tidak adanya padu serasi antara tata ruang kehutanan dengan tata ruang provinsi Kalimantan Tengah adalah terjadinya konflik dalam penggunaan ruang, dimana terjadi penggunaan kawasan hutan tidak prosedural untuk perkebunan sawit di dalam kawasan hutan di Provinsi Kalimantan Tengah sebanyak 282 unit perusahaan sawit seluas 3,9 juta hektar.Upaya penyelesaian permasalahan penggunaan kawasan hutan untuk perkebunan sawit di Provinsi Kalimantan Tengah diakukan dengan revisi kebijakan tentang alih fungsi hutan PP nomor 60 tahun 2012 yang memberikan kesempatan bagi perkebunan sawit yang berdasarkan Undang-Undang Kehutanan berada di dalam kawasan hutan namun berdasarkan RTRWP Provinsi Kalimantan Tengah berada di kawasan APL maupun budidaya, diberikan kesempatan untuk mengurus perijinannya.
