Global deforestation has reached an alarming level, causing widespread impacts on ecosystems, biodiversity, and human well-being. Forests, as complex and dynamic ecosystems, play a central role in carbon storage, climate regulation, and the provision of essential ecosystem services. The continuous loss of forests disrupts ecological balance and leads to consequences that are difficult to reverse.
Deforestation and Its Difference from Forest Degradation
Deforestation is defined as the conversion of forest land to other uses such as agriculture, urban development, or infrastructure, typically in a permanent manner (FAO, 2010). In contrast, forest degradation refers to the decline in the quality and function of forest ecosystems without complete loss of forest cover.
Root Causes of Deforestation
Deforestation is a complex phenomenon triggered by the interaction of various factors:
- Agricultural Expansion: The growing global demand for agricultural products, particularly livestock and commodity crops such as soybeans and oil palm, drives the conversion of forests into agricultural land (FAO, 2010).
- Logging: The demand for wood and wood-based products, both legally and illegally, leads to unsustainable logging practices.
- Mining and Infrastructure Development: Land clearing for mining, as well as the construction of roads, railways, and supporting infrastructure, causes forest fragmentation and degradation.
- Forest Fires and Energy Demand: Fires often caused by land clearing through burning, and the use of fuelwood and charcoal as energy sources, further worsen deforestation (Global Forest Watch, 2023).
Consequences of Deforestation
The impacts of deforestation are multidimensional, including:
- Loss of Biodiversity: Forests are home to more than half of the world's plant and animal species. A study published in Science (2022) shows that land-use change, including deforestation, is a major driver of biodiversity loss. A UN report indicates that approximately 1 million species are at risk of extinction (UNEP, 2022).
- Climate Change: Forests act as carbon sinks. The process of deforestation releases stored carbon, exacerbating greenhouse gas emissions and accelerating global warming.
- Disruption of the Hydrological Cycle: The loss of forest cover disrupts evapotranspiration and infiltration processes, resulting in decreased rainfall, increased risk of drought and flooding, and degradation of water quality.
- Socio-Economic Impacts: Communities dependent on forests for livelihoods, food, and traditional medicine face the risk of losing income sources and potential conflicts over natural resources.
- Case Study: Orangutans in Indonesia: Habitat fragmentation caused by deforestation severely harms endemic species such as orangutans. The IUCN classifies all three orangutan species (Sumatran, Bornean, and Tapanuli) as “Critically Endangered” due to forest conversion into plantations and agricultural land (IUCN, 2021).
Deforestation Data Review in Indonesia
Indonesia, as one of the countries with the largest tropical rainforests, has experienced significant deforestation. According to data from the Ministry of Environment and Forestry (MoEF), net deforestation in 2021–2022 reached 104,000 hectares, a decrease of 8.4% compared to the 113.5 thousand hectares recorded in 2020–2021. Meanwhile, Global Forest Watch reported that in 2022, Indonesia lost around 230,000 hectares of primary forest, resulting in emissions of 117 million tons of CO₂ (Global Forest Watch, 2022). This data discrepancy stems from differences in forest definitions, monitoring methodologies, and reporting periods.
Implications for Biodiversity
Increasing forest fragmentation leads to habitat isolation, reduced genetic diversity, and disrupted ecosystem networks. These impacts threaten the survival of endemic flora and fauna, such as the Sumatran tiger, Javan rhinoceros, and various bird species, in addition to orangutans (IUCN, 2021).
Efforts to Address Deforestation and Sustainability Strategies
Various measures have been undertaken to address deforestation, including:
- Policies and Regulations: The Indonesian government has enacted a moratorium on primary forest and peatland clearing, along with commitments to reduce greenhouse gas emissions.
- Conservation and Restoration Initiatives: Ecosystem conservation and restoration programs are implemented by government and non-governmental organizations.
- Sustainable Forest Management: The implementation of forest certification and responsible management practices aims to reduce pressure on natural forests.
- Partnerships and Collaboration: Synergy between government, the private sector, and local communities is key to the success of conservation policies.
- Public Education and Awareness: Enhancing environmental literacy through education plays an important role in supporting conservation efforts.
- Integrated Landscape Approaches: Holistic management that considers the interaction between forests, agriculture, and other land uses is expected to optimize both ecological and economic benefits (IPBES, 2022).
Deforestation is a global crisis that demands collective action. Forest loss not only accelerates climate change and reduces biodiversity but also undermines the socio-economic well-being of communities. Through stronger policies, sustainable forest management, and increased stakeholder collaboration, it is hoped that the trend of deforestation can be reversed to create a greener and more sustainable planet.
