A study published in Environmental Management, examined the effect of rainforest conversion into rubber plantations on soil's dissolved organic carbon (DOC).
DOC is the organic carbon that can pass through a filter with a pore size of 0.22–0.7 micrometers. DOC is a significant component of the biogeochemical marine system and is important in many environments.
DOC is the Earth's largest reservoir of organic matter, comparable to the amount of carbon in atmospheric CO2. Changes in DOC reservoir size can significantly affect atmospheric CO concentration.
DOC is a key component of water chemistry and plays a central role in limnological processes.
DOC is a potential source of carbon and energy for heterotrophic organisms. DOC is important in many fields, including: Pollution abatement, Industrial processing, and Drinking water quality.
Rubber production is a vital industry in Southeast Asia, mostly in countries like Thailand, Indonesia, and Malaysia, which collectively account for the majority of the world's natural rubber production.
The process involves tapping rubber trees to extract latex, which is then processed into various rubber products. Though rubber is an essential commodity with numerous applications, its production has historically been associated with deforestation, habitat loss, and social issues such as land grabbing and labor exploitation.
Deforestation and Habitat Loss |
Conventional rubber production involves monoculture plantations that lead to large-scale deforestation, causing habitat destruction and loss of biodiversity in tropical rainforests, particularly in Southeast Asia. |
Agrochemical Pollution |
The use of pesticides and fertilizers in rubber cultivation can pollute soil and waterways, leading to further environmental degradation and negatively impacting local ecosystems and water quality. |
Social Impact on Smallholder Farmers |
Smallholder farmers, who represent a major portion of the rubber workforce, face low wages, limited access to healthcare and education, and high vulnerability to price volatility in the global rubber market, which impacts their economic stability and quality of life. |
A 2023 study published in Nature (Mongabay) found that over 4 million hectares (10 million acres) of forest have been cleared for rubber plantations in Southeast Asia since 1993.
In South-East Asia, rubber monoculture has taken over 250,000 hectares of natural forest and 61,000 hectares of protected area between 2005 and 2010. Over half of these plantations are in areas which are susceptible to insufficient water availability and soil erosion. Scientists have also linked rubber monoculture to reduction in water reserves, soil productivity and biodiversity in South-East Asia.
Technology and innovation also play a significant role in advancing sustainable rubber production. For instance, research is underway to develop drought-resistant rubber tree varieties that can thrive in changing climatic conditions, reducing the need for irrigation and water resources. Furthermore, advances in agricultural practices, such as precision farming techniques and remote sensing technologies, enable farmers to optimize resource use and minimize waste.
The transition towards sustainable rubber production in Southeast Asia represents a significant step towards building a more environmentally resilient and socially equitable future.
By embracing practices such as agroforestry, organic farming, and technological innovation, the rubber industry can minimize its environmental footprint, protect biodiversity, and improve the livelihoods of millions of smallholder farmers across the region.
