Climate change has a significant impact on the ASEAN region, which consists of 10 member countries with diverse geographic and social characteristics. Some of the main impacts of climate change include increasing temperatures, changes in rainfall patterns, and an increase in the frequency of natural disasters such as floods and droughts. One of the most striking effects of climate change in ASEAN is an increase in average temperatures. Data shows that temperatures in the region could increase by between 1.5°C and 2°C by 2050. This could have serious impacts on human health, such as an increased risk of respiratory diseases and infections related to extreme weather. Changes in rainfall patterns are also an important issue. Countries such as Indonesia and the Philippines are experiencing unpredictable rainfall, with some areas experiencing increasingly frequent flooding, while others are experiencing severe drought. Agriculture, which is an important sector for the ASEAN economy, has been particularly affected. Farmers have to adapt to changing conditions, and this often requires new technologies and methods that are expensive and not always available. The fisheries sector in ASEAN also faces threats. Changes in sea temperature and increasing acidity can impact marine ecosystems, disrupting food chains and reducing catches. Countries such as Vietnam and Thailand that depend on fishing for the livelihoods of millions of people are vulnerable to these impacts. A decline in fish stocks could cause a food crisis and increase social tensions. Major cities in the region, such as Jakarta, Manila and Bangkok, face the risk of severe sea level rise. With a large population living in coastal areas, many communities here are at risk of being submerged, forcing people to move and causing social and economic problems. This is why the need for investment in adaptive and mitigation infrastructure is becoming increasingly urgent. Natural disasters related to climate change also trigger economic problems. For example, floods that occur in Myanmar and Thailand often cause large economic losses and hamper growth. Disaster management costs increase the financial burden on the government and society. Education is also a crucial factor. Communities need to be empowered to understand and deal with climate change. Educational programs on sustainability and environmentally friendly practices should be emphasized for future generations. Regional cooperation in ASEAN has proven important in mitigating the impacts of climate change. Initiatives such as the ASEAN Agreement on Disaster Management and Emergency Response (AADMER) help member countries to support each other in disaster management. This collaboration can create a holistic approach in overcoming the challenges faced by climate change. It is also important to promote the use of renewable energy throughout the region. With the vast potential of solar and wind energy, investing in green technology can reduce dependence on fossil fuels and help reduce greenhouse gas emissions. Finally, policy makers in ASEAN need to work more intensively to formulate efficient and sustainable policies. Adaptation and mitigation policies must be evidence-based and designed to create a more resilient environment for communities. Appropriate interventions can help ASEAN countries to be better prepared to face the increasingly real impacts of climate change.
