Assessment of ecosystem functions of rubber plantations using the native tropical forest as a reference system


Natural rubber (hereafter rubber) is a valuable global commodity owing to its multiple uses in every household. It is mainly produced by the sap (latex) of rubber trees (Hevea brasiliensis Muell. Arg) and has an essential role in reducing poverty in rural communities of many tropical countries. As it is a native species of the Amazon basin, Brazil was the primary source of rubber supply till the 19th century. It was first introduced in Asia in the early 20th century, and since then, the expansion of rubber plantation area and latex production has been occurring in this region. Nowadays, 89% of the rubber used worldwide is produced in this region including, Thailand, Vietnam, Indonesia, India, China, and Malaysia, as the leading rubber producing countries, with approximately 60% solely originating from Thailand and Indonesia. This expansion on these historically non-traditional areas is still ongoing, with an additional 2 Mha of land being used for rubber cultivation between 2010 and 2017. Although rubber cultivation has improved the economic status of farmers, it has altered the habitat’s ecology and ecosystem functions. In this seminar, I will explore our knowledge on the impact of rubber plantations on multiple ecosystem functions, particularly related to carbon storage, nutrient cycling, and biodiversity. I will also discuss important research gaps, strategies to improve ecosystem functions, and policies for sustainable cultivation. Besides this, I will also discuss an important finding related to an individual function (i.e., soil C storage) in the context of rubber plantation.
