Re-envisioning Sustainable Oil-Palm in SE Asia
نویسنده
چکیده
In Southeast Asia, expansion of oil-palm agriculture, in combination with other industries (logging, fiber, and mega-dams), is transforming significant portions of the landscape threatening biodiversity, key ecosystem services, and human cultural diversity. While transformative answers to these multifaceted environmental issues seem daunting, the conservation biology literature provides a road map for effective techniques to mitigate environmental degradation while allowing for thoughtful, well-planned economic growth. I suggest that the lack of strict operational definitions and a holistic approach to sustainability are the two most critical factors hindering development of sustainable oil-palm agriculture. The task for environmental practitioners is to succinctly define quantifiable long-term sustainability practices and persuade governments and industries that it is in their best interest not to dismiss environmental concerns. If adopted, oil-palm and other industries in SE Asia could become a sustainable model for the world by preserving diverse biological and human communities while expanding economic interests. Impact of oil-palm agriculture and other extractive industries in SE Asia Oil-palm (Elaeis guineensis) agriculture has received increased attention in the recent decade because its expansion threatens tropical forests, the diverse flora and fauna these forests harbor, and the critical ecosystem services these forests support (Fitzherbert et al. 2008). Particular focus has centered on Malaysia and Indonesia, as they are the two largest oil-palm producing countries, Indonesia (4.1 Mha) and Malaysia (3.6 Mha) (Koh and Wilcove 2008), and they harbor 80% of SE Asia’s remaining primary forests (FAO 2010). However, focusing on just oil-palm ignores the many varied and interconnected ecological challenges the region is currently facing. For example, logging and fiber concessions (areas of forests that are converted to monocultures of pulp-producing trees) account for more forest loss than oil-palm concessions (Abrood et al. 2015). These industries along with others (e.g., mining and mixed concessions) are linked to oilpalm expansion because, once land is logged or mined, it is considered degraded and additional concessions may be provided to allow for oil-palm agriculture (Koh and Wilcove 2008). Combined, these industries have contributed to significant loss of tropical forests in the region. Estimates of net deforestation, which incorporates gross deforestation and forest regeneration, indicate that deforestation rates in SE Asia have been between 1.44 and 1.78 M ha yr-1 for the 1 Wallace M.

متن کاملSE Asian Palms for Agroforestry and Home Gardens
Throughout SE Asia, palms are important in agroforestry systems and homegardens. Most species are used for multiple purposes based on both physical and nutritional properties of the palms. Except for a few commodities of worldwide importance such as palm oil and coconut, many palm products either do not figure in trade statistics, or they are merged with other products in a way, which makes it ...

Oil palm is the world's leading source of vegetable oil and fat. Dura, Pisifera and Tenera are three forms of oil palm. The genome sequence of Pisifera is available whereas the Dura form has not been sequenced yet. We sequenced the genome of one elite Dura palm, and re-sequenced 17 palm genomes. The assemble genome sequence of the elite Dura tree contained 10,971 scaffolds and was 1.701 Gb in l...

Southeast Asia is the epicentre of world palm oil production. Plantations in Malaysia have increased 150% in area within the last decade, mostly at the expense of tropical forests. Maps of the aboveground carbon density (ACD) of vegetation generated by remote sensing technologies, such as airborne LiDAR, are vital for quantifying the effects of land use change for greenhouse gas emissions, and ...

Expansion of oil palm plantations has led to extensive wildlife habitat conversion in Southeast Asia [1]. This expansion is driven by a global demand for palm oil for products ranging from foods to detergents [2], and more recently for biofuels [3]. The negative impacts of oil palm development on biodiversity [1, 4, 5], and on orangutans (Pongo spp.) in particular, have been well documented [6,...
