Oil Palm Plantation

Purpose The purpose of this paper is to develop strategies for potential environmental impacts as a result of institutional arrangement and development of oil palm downstream industry both regionally and nationally. Design/methodology/approach The research location is in the areas potential for oil palm plantation development, either by plasma through BUMN and BUMS or self-supporting by the society. The research location will be divided into two parts, namely, the land area and the coastal area. The Riau land areas are Regency of Kampar, Rokan Hulu, and Kuantan Singingi, while Riau coastal areas are Regency of Pelalawan, Siak, Bengkalis, Indragiri Hilir, Indragiri Hulu and Rokan Hilir. Both research areas have different productivity due to the different soil fertility levels. The sustainability level of oil palm plantation from the socio-economic and environmental aspects is analyzed using the multi-dimensional scaling approach modified into Rapid Appraisal-Index Sustainability of Palm Oil Management. Findings In Riau Province, the development of oil palm is quite rapid. This is reasonable for several reasons which include the following supporting factors: the geographical condition of the Riau region is very supportive; the high demand for palm oil derivative products; the existence of market guarantee for oil palm farmers; the higher income oil palm generates than other plantation crops; and the relatively flat area. Most of the problems faced by oil palm farmers are the use of less good seeds, the length of the fruit laying at the location of the plantation, the inadequate production road, the relatively far distance to palm oil mill (POM) (National Agency of Drug and Food Control), the tendency of determining the unilateral revenue of the POM, the collectively measurement of revenue and the general revenue information. The development of oil palm plantations has created an entrepreneurial capability for farmers who are able to capture business opportunities in the agricultural sector, especially the plantation sub-sector. Originality/value The originality of this paper shows the comprehensively control strategy, potential of environmental impact and palm oil plantation. The method used for data collection was rapid rural appraisal method because accurate information is needed in a limited time as it relates to decisions related to village development that must be taken immediately. The study area was conducted in Riau Province because Riau Province is one of the biggest palm oil producers in Indonesia. The study sites will be divided into two, namely, the land area and the coastal area.

The Impact

In the past decades, carbon dioxide (CO2) emissions have become an important issue for many researchers and policy makers. The focus of scientists and experts in the area is mainly on lowering the CO2 emission levels. In this article, panel data is analyzed with an econometric model, to estimate the impact of renewable energy, biofuels, bioenergy efficiency, population, and urbanization level on CO2 emissions in European Union (EU) countries. Our results underline the fact that urbanization level has a negative impact on increasing CO2 emissions, while biofuels, bioenergy production, and renewable energy consumption have positive and direct impacts on reducing CO2 emissions. Moreover, population growth and urbanization level are negatively correlated with CO2 emission levels. The authors’ findings suggest that the public policies at the national level must encourage the consumption of renewable energy and biofuels in the EU, while population and urbanization level should come along with more restrictions on CO2 emissions.

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.

There are three patterns of smallholder oil palm plantation in North Mamuju regency, ie plasma, IGA (Income Generating Activity), and mandiri (independent). Independent smallholder plantations are plantations managed by the community themselves without the involvement of others. While the partnership patterns can be divided into plasma and IGA. The partnership is a form of fostering of smallholders plantations by large private plantation in this area. This study aims to determine the amount of oil palm production on smallholder plantations and the factors that affect. The research was conducted in North Mamuju Regency, West Sulawesi Province which has the widest smallholder oil palm plantation in Sulawesi Island with various pattern. Four villages in two sub-districts were chosen purposively consideration with having three patterns of smallholder plantations. The sampling of farmers using snowball method after stratification in each pattern. Selected 35 plasma farmers, 70 IGA farmers, and 55 independent farmers. Data analysis was performed with Cobb-Doulas function model in the normalized logarithm, using Eviews 6 software. The findings are the average production of 56,840 kg, with productivity of 20,300 kg/ha. Input of land area, NPK fertilizer, age of oil palm crops, outside family labor, frequency of estate sanitation and distance of estate to river is the determinant input to production. Input land area is found as the most elastic input. However, land use for oil palm plantations should still refer to existing legislation.

Converting of tropical rain forest into plantation and agriculture land uses has been claimed as a main factor that affects to global warming and climate change. In order to provide a comprehensive information of the issue, a field observation on  peat properties in relation to CO2 emission under several land use types had been done  at Lubuk Ogong Village, Pelalawan District, Riau Province from May 2011-April 2012. Five land use types, namely A. mangium, bare land, oil palm, rubber, and secondary forest have been selected in the study site. Observations were made for chemical and physical properties, above and below ground C-stock and CO2 emissions. The results showed a higher variation of peat depth and a below ground C-stock was almost linearly with a peat depth. Below ground C-stock for each land use was around 2848.55 Mg ha-1, 2657.08 Mg ha-1 5949.85 Mg ha-1,  3374.69 Mg ha-1, 4104.87 Mg ha-1 for secondary forest, rubber, oil palm, bare land, and A. mangium, respectively. The highest above ground C-stock observed on a secondary forest was 131.5 Mg ha-1, followed by the four years A. mangium 48.4 Mg ha-1, the 1-2 years A. mangium 36.6 Mg ha-1, and the 4 years A. mangium 34.4 Mg ha-1. While, CO2 emissions in the study sites were 66.58±21.77 Mg ha-1yr-1, 66.17±25.54 Mg ha-1yr-1, 64.50±31.49 Mg ha-1yr-1, 59.55±18.30 Mg ha-1yr-1, 53.65±16.91 Mg ha-1yr-1 for bareland, oil palm, secondary forest, A. mangium, and rubber, respectively.

The Impact

&lt;p&gt;Anthropogenic activities, and in particular the use of synthetic nitrogen (N) fertilizer, have a significant influence on soil nitrous oxide (N&lt;sub&gt;2&lt;/sub&gt;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&amp;#8217;s oil palm sector. However, studies on the impact of N fertilizers on N&lt;sub&gt;2&lt;/sub&gt;O emissions&amp;#160;from&amp;#160;tropical peatland are limited. Thus, long-term monitoring was conducted to investigate the effects of N fertilization on soil N&lt;sub&gt;2&lt;/sub&gt;O emissions. This study was conducted in an oil palm (&lt;em&gt;Elaeis guineensis Jacq&lt;/em&gt;.) plantation located in a tropical peatland in Sarawak, Malaysia. Monthly soil N&lt;sub&gt;2&lt;/sub&gt;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&lt;sup&gt;&amp;#8722;1&lt;/sup&gt;), moderate N (recommended rate) (T3, 62.2 kg N ha&lt;sup&gt;&amp;#8722;1&lt;/sup&gt;), and high N (T4, 124.3 kg N ha&lt;sup&gt;&amp;#8722;1&lt;/sup&gt;), from January 2010 to December 2013 and from January 2016 to December 2017. The only N fertiliser rate to significantly increase (p&lt;0.05) annual cumulative N&lt;sub&gt;2&lt;/sub&gt;O emissions was 124.3 kg N ha&lt;sup&gt;-1&lt;/sup&gt; (T4). Increased&amp;#160;in water-filled pore space (WFPS) (&gt;70%) with a decrease in both N&lt;sub&gt;2&lt;/sub&gt;O flux and nitrate (NO&lt;sub&gt;3&lt;/sub&gt;&lt;sup&gt;&amp;#8722;&lt;/sup&gt;) implies that complete denitrification has taken place.&amp;#160;Increased in NO&lt;sub&gt;3&lt;/sub&gt;&lt;sup&gt;-&lt;/sup&gt;&amp;#160;uptake by oil palm with an increase in WFPS decreased NO&lt;sub&gt;3&lt;/sub&gt;&lt;sup&gt;-&lt;/sup&gt; concentration in soil, resulting in the reduction of N&lt;sub&gt;2&lt;/sub&gt;O emission. This study highlights the importance of WFPS on denitrification and &lt;span&gt;N uptake &lt;/span&gt;&lt;span&gt;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.&lt;/span&gt;&lt;/p&gt;&lt;p&gt;Keywords: WFPS, oil palm yield, NO&lt;sub&gt;3&lt;/sub&gt;&lt;sup&gt;-&lt;/sup&gt;, N uptake&lt;/p&gt;
