The expansion of oil palm plantation has been claimed as a major driver of biodiversity loss in the tropics, including birds. To date, only a few studies have been conducted to document the variation of bird diversity in different land cover within oil palm plantation. Therefore, it is necessary to conduct the research to investigate the variation of bird diversity. The objective of this study to identify the diversity of bird in different land cover within oil palm plantation. The observation of bird diversity was done in young stand of oil palm, old stand of oil palm, smallholder oil palm and in secondary forest as high stock carbon as natural reference before converting in to oil palm. The survey was done in August 2017 in Central Kalimantan, Indonesia. Data of bird species were recorded by direct observation using transect method. To calculate the diversity value of birds at different land cover, we used Margalef Index (Dmg) and Comunity similarity (IS). The result showed that the number of species and species diversity was highest at high carbon stock area which the number of species was 25 species and Margalef Index was 5.99. The young stand of oil palm have the highest evenness index (0.93), while the highest similarity index was observed in old stand of oil palm and in smallholder oil palm. Our study concludes that the existence of high carbon stock areas within oil palm plantation had a positive influence in increasing bird diversity. From a conservation perspective, retaining of natural habitat such as high carbon stock within oil palm plantation is one strategy to conserve biodiversity.

Abstract. Over recent decades oil palm plantations have rapidly expanded across Southeast Asia (SEA). According to the United Nations, oil palm production in SEA increased by a factor of 3 from 1995 to 2010. We investigate the impacts of current (2010) and future (2020) oil palm expansion in SEA on surface-atmosphere exchange and the resulting air quality in the region. For this purpose, we use satellite data, high-resolution land maps, and the chemical transport model GEOS-Chem. Relative to a no oil palm plantation scenario (~ 1990), overall simulated isoprene emissions in the region increase by 13 % due to oil palm plantations in 2010 and a further 11 % by 2020. In addition, the expansion of palm plantations leads to local increases in ozone deposition velocities of up to 20 %. The net result of these changes is that oil palm expansion in SEA increases surface O3 by up to 3.5 ppbv over dense urban regions, and could rise more than 4.5 ppbv above baseline levels by 2020. Biogenic secondary organic aerosol loadings also increase by up to 1 μg m−3 due to oil palm expansion, and could increase a further 2.5 μg m−3 by 2020. Our analysis indicates that while the impact of recent oil palm expansion on air quality in the region has been significant, the retrieval error and sensitivity of the current constellation of satellite measurements limit our ability to observe these impacts from space. Oil palm expansion is likely to continue to degrade air quality in the region in the coming decade and hinder efforts to achieve air quality regulations in major urban areas such as Kuala Lumpur and Singapore.

The Impact

This study aims to determine the impact of the existence of palm oil plantations on the socio-economic conditions of the people in Kamipang District, Katingan District. The type of data used in this study is secondary data obtained from BPS, Sub-District Offices, village/district, and the private sector and primary data obtained directly from different respondents in Kamipang Subdistrict to determine the number of samples used by purposive sampling technique or sampling. intentionally that is equal to 20% of the total population or as many as 30 respondents. The results of the study show that the management of oil palm plantations has an impact on social conditions that are very influential, namely after the existence of the oil palm plantation company PT Arjuna Utama Sawit. The impact is such as access to education in Kamipang Subdistrict, new economic activities such as lodging, restaurants, crossing services, and salons. After the existence of a coconut plantation company, PT. Arjuna Utama Sawit, those who were previously less prosperous are now more prosperous. They arrived at zero economic conditions, the impact of the existence of a sick coconut plantation company, PT. Arjuna Utama Sawit for economic conditions greatly affects that is after the existence of oil palm plantation companies PT. Arjuna Utama Sawit compared to the existence of a plantation company PT. Arjuna Utama Sawit.

The Impact

<p>Anthropogenic activities, and in particular the use of synthetic nitrogen (N) fertilizer, have a significant influence on soil nitrous oxide (N<sub>2</sub>O) emission from oil palm plantation on tropical peatland. Finding a suitable N rate for optimum N uptake efficiency and yield with low environmental impact and production cost is crucial for the economic growth of Malaysia’s oil palm sector. However, studies on the impact of N fertilizers on N<sub>2</sub>O emissions from tropical peatland are limited. Thus, long-term monitoring was conducted to investigate the effects of N fertilization on soil N<sub>2</sub>O emissions. This study was conducted in an oil palm (<em>Elaeis guineensis Jacq</em>.) plantation located in a tropical peatland in Sarawak, Malaysia. Monthly soil N<sub>2</sub>O fluxes were measured using the closed-chamber method in a control (T1, without N fertilization), and under three different N treatments: low N (T2, 31.1 kg N ha<sup>−1</sup>), moderate N (recommended rate) (T3, 62.2 kg N ha<sup>−1</sup>), and high N (T4, 124.3 kg N ha<sup>−1</sup>), from January 2010 to December 2013 and from January 2016 to December 2017. The only N fertiliser rate to significantly increase (p<0.05) annual cumulative N<sub>2</sub>O emissions was 124.3 kg N ha<sup>-1</sup> (T4). Increased in water-filled pore space (WFPS) (>70%) with a decrease in both N<sub>2</sub>O flux and nitrate (NO<sub>3</sub><sup>−</sup>) implies that complete denitrification has taken place. Increased in NO<sub>3</sub><sup>-</sup> uptake by oil palm with an increase in WFPS decreased NO<sub>3</sub><sup>-</sup> concentration in soil, resulting in the reduction of N<sub>2</sub>O emission. This study highlights the importance of WFPS on denitrification and <span>N uptake </span><span>by oil palm in tropical peatland. This needs to be taken into account for the accurate assessment of N dynamics in oil palm plantations on tropical peatland in order to enhance N fertilization management strategies and counteract anthropogenic activities that produce greenhouse gases.</span></p><p>Keywords: WFPS, oil palm yield, NO<sub>3</sub><sup>-</sup>, N uptake</p>

Our research team worked with Nakanai land-holders in Papua New Guinea to perform the first survey of butterflies in the Lake Hargy caldera of West New Britain Province. Methods included modified Pollard transects quantifying sampling effort based on aerial netting and visual observations, as well as traps baited with fermenting fruit. Results were compared with surveys on the adjacent Hargy Oil Palm plantation. Our sampling yielded 312 specimens representing 73 species; of these, 50 were limited to primary rainforest, 12 to oil palm plantation and 11 species occurred at both sites. Four species are newly recorded for New Britain, including one potentially invasive species on Citrus. Singleton specimens made up the largest abundance class in the data set, representing 34% of records in primary rainforest. Sixty-two percent of the butterfly taxa recorded are regionally endemic to the Bismarck island chain or to New Britain in particular. Calculated levels of similarity between sites ranged from 0.151 to 0.262, suggesting the oil palm and rainforest habitats supported highly distinct species assemblages. Although rapid assessment data such as these are necessarily limited in scope, they can still aid in documenting the impact on biodiversity from conversion of primary tropical rainforest to oil palm monoculture.
