Oil palm is one of the most valuable crops in the humid tropics, dominating the global vegetable fat market and also providing biofuel. The major global producers are Indonesia and Malaysia, where oil palm monocultures now cover over 11.5 million hectares of land, by replacing natural forests. This change has had seriously damaging effects on the biodiversity of flora and fauna, but also alters the emissions of the greenhouse gases (GHGs) nitrous oxide, methane and carbon dioxide, which in turn affects the global climate. Scientists are currently investigating whether biodiversity can be improved by encouraging ground vegetation within and around the monocultures so as to minimise environmental damage and maximise co-benefits such as soil protection, pest control and conservation of biodiversity. Such practices include creating reserves and buffer strips of native vegetation and management of vegetation in the plantations themselves. The success of these management practices in delivering ecosystem services and the impact on GHG emissions are uncertain, and there is a real need for an evidence-base to guide improvements in the environmental sustainability of oil palm management.A key proposed management strategy is to promote a more developed, more diverse understory within the plantation. As well as increasing biodiversity by creating a more complex habitat and links between forest remnants, the understory may sequester carbon in above-ground biomass and through maintenance of plant-soil interactions. This project specifically tests how different understory management practices affect GHG emissions in oil palm plantations. We expect that the understory may be one important aspect in determining GHG emissions because oil palms are routinely fertilised with nitrogen, of which a significant proportion can be lost to the atmosphere as the GHG nitrous oxide and leached to the rivers as nitrate and organic nitrogen compounds. A large understory biomass can potentially increase plant nitrogen uptake, so effectively could reduce nitrous oxide emissions and leaching. We urgently need to quantify the greenhouse gas emissions in relation to a range of plantation management strategies so we can provide accurate environmental assessments and identify best agricultural practices. This project will collaborate with industry partners and disseminate findings to the Round Table of Sustainable Palm Oil (RSPO) and the Indonesian Sustainable Palm Oil (ISPO) board to feed in to the development of industry guidelines. The area of RSPO-certified plantations is rapidly growing, so identifying best agricultural practices will have a large impact.The time scale for research relating to management options is critical for influencing decision making in the near-future; in Indonesia, most OP plantations were established in the late 1980s and early 1990s. Due to the 25 - 30 year life cycle of OP plantations, nearly half are due to be clear-cut for replanting in the near-future. Hence, it is vital to understand replanting and restoration options which simultaneously allow for high productivity as well as supporting biodiversity and minimising GHG emissions. The proposed project, AP-GRO, will be a collaboration between the 'The Biodiversity and Ecosystem Function in Tropical Agriculture' (BEFTA) project team in Indonesia, consisting of the industry partner Sinar Mas Agro Resources Technology Corporation Research Institute (SMARTRI) and, in the UK, the University of Cambridge and the NERC Centre for Ecology and Hydrology (CEH). We will bring together CEH's long standing expertise in greenhouse gas research with the established BEFTA long-term experiment to investigate the impact of diversifying understory vegetation in oil palm plantations on GHG emissions in Sumatra, Indonesia.

油棕是潮湿的热带地区最有价值的农作物之一，在全球蔬菜脂肪市场中占主导地位，并提供生物燃料。全球主要生产商是印度尼西亚和马来西亚，通过取代天然林，油棕单一栽培现在覆盖了超过1,150万公顷的土地。这种变化对动植物的生物多样性产生了严重破坏的影响，但也改变了温室气体（GHGS）一氧化二氮，甲烷和二氧化碳的排放，从而影响全球气候。科学家目前正在调查是否可以通过鼓励单一培养物地和周围的地面植被来改善生物多样性，以最大程度地减少环境损害并最大程度地提高共同利益，例如土壤保护，害虫控制和生物多样性的保护。这样的做法包括创建本地植被的储量和缓冲液条以及种植园本身的植被管理。这些管理实践在提供生态系统服务方面的成功以及对温室气体排放的影响尚不确定，并且确实需要循证基础来指导油棕管理环境可持续性的改善。拟议的关键管理策略是促进种植园中一个更加发达，更多样化的林下。除了通过建立更复杂的栖息地和森林残留物之间的联系来增加生物多样性外，底层可以隔离地上生物量中的碳和维持植物土壤相互作用。该项目专门测试了不同的林下管理实践如何影响油棕种植园的温室气体排放。我们预计林里可能是确定温室气体排放的一个重要方面，因为油棕常规用氮施肥，当温室温室氧化温室气体氧化温室剂并以硝酸盐和有机氮化合物为河流时，大气中可能会丢失很大的比例。 。大型林木生物质可以潜在地增加植物氮的摄取，因此有效地可以减少一氧化二氮的排放和浸出。我们迫切需要根据一系列种植园管理策略来量化温室气体排放，以便我们可以提供准确的环境评估并确定最佳的农业实践。该项目将与行业合作伙伴合作，并将发现结果传播到可持续棕榈油（RSPO）和印尼可持续棕榈油（ISPO）董事会的圆桌会议上，以供行业指南的制定。 RSPO认证的种植园的领域正在迅速增长，因此确定最佳的农业实践将产生巨大影响。与管理方案有关的研究时间尺度对于影响近乎未来的决策至关重要。在印度尼西亚，大多数OP种植园是在1980年代末和1990年代初建立的。由于OP种植园的25至30年生命周期，将近一半的人要在近未燃料中重新种植。因此，了解重新种植和恢复方案至关重要，同时允许高生产率以及支持生物多样性并最大程度地减少温室气体排放。拟议的项目AP-GRO将是印度尼西亚的“热带农业生物多样性和生态系统功能”（BEFTA）项目团队之间的合作，由行业合作伙伴Sinar MAS MAS Agro Resources Corexpation Corporation（Smartri）组成在英国，剑桥大学和NERC生态与水文学中心（CEH）。我们将通过既定的Befta长期实验来汇集CEH在温室气体研究方面的长期专业知识，以调查在印度尼西亚苏门答腊的温室气植林中植被多样化的影响。
