Climate Change Impact on Sri Lanka: Coastal Erosion and Agriculture Challenges

Climate change poses a significant threat to Sri Lanka, impacting both human and natural systems.

Roughly 50 percent of its 22 million citizens live in low-lying coastal areas, making them vulnerable to sea level rise. This directly affects their livelihoods and safety.

The island’s economy faces potential setbacks due to these climatic shifts. According to the World Bank, living standards could decline by around 5 to 7 percent.

With significant economic sectors like agriculture, fisheries, and tourism at risk, the national economy might suffer long-term consequences.

The Ministry of Finance is actively working on adaptation plans to mitigate these impacts.

By implementing these strategies, Sri Lanka aims to build resilience against the ongoing challenges posed by climate change.

How Has Climate Change Impacted Sri Lanka

Climate change has had significant effects in Sri Lanka, posing serious risks to both the environment and the people.

The island, with a population of 22 million, is heavily impacted by extreme weather events.

Vulnerable Areas: Coastal regions, particularly in the west, south, and southwest, face rising sea levels. This endangers livelihoods and homes, making these areas highly vulnerable.

Water Availability: Changes in rainfall patterns have caused severe droughts in the dry zone. These droughts threaten water availability, impacting both agriculture and daily life.

Agriculture: Agriculture, a vital part of Sri Lanka’s economy, suffers from inconsistent rainfall and droughts.

Crops like rice are particularly affected, jeopardizing food security.

Natural Disasters: Floods and landslides have become more frequent, damaging infrastructure and displacing people. Colombo and other urban areas are at increasing risk of flood-related disasters.

Biodiversity and Ecosystems: Climate change threatens Sri Lanka’s rich biodiversity.

Coastal ecosystems and rural communities face habitat fragmentation and over-exploitation of natural resources.

Economic Impact: The strain on natural resources affects the GDP, with reduced agricultural productivity and increased costs for disaster recovery.

Small-scale farmers face indebtedness due to crop failures and extreme events.

Rural Communities: Many rural communities depend on agriculture and are directly affected by climate change.

Changes in water availability and extreme weather events disrupt their livelihoods and increase poverty.

Biodiversity Conservation: Efforts to conserve biodiversity are challenged by climate change. Protecting endangered species and maintaining ecosystem services becomes more difficult amid changing climatic conditions.

How Is Sri Lanka Going to Be Impacted by Future Climate Change

Sri Lanka faces many challenges due to future climate change. The rising temperatures and shifting rainfall patterns pose serious threats to the country’s natural systems and economy.

Temperature and Precipitation

  • Average temperatures are expected to rise, impacting agriculture and water resources.
  • Changes in seasonal and annual rainfall will affect the availability of fresh water and the productivity of crops, leading to potential food insecurity.

Economic Impact

  • Key sectors like agriculture, fisheries, and tourism will face disruptions.
  • Poverty levels may increase as livelihoods, especially those dependent on these sectors, become unstable.

Health and Well-being

  • Healthcare systems need to adapt to new climate realities, such as diseases that thrive in warmer climates.
  • Special focus must be given to vulnerable groups, including women, youth, and people living in poverty.

Disaster Preparedness

  • Increased occurrences of extreme weather events like floods and droughts require stronger disaster preparedness and mitigation strategies.
  • Investments in sustainable development and renewable energy can help improve resilience.

Food Security

  • Seasonal cycles and rainfall patterns play a crucial role in food production.
  • Disruptions in these patterns can lead to food insecurity, affecting poverty reduction efforts.

Policy and Governance

  • Emphasis on gender equality and human rights is vital in decision-making processes.
  • Meeting the Sustainable Development Goals (SDGs) involves incorporating climate resilience into national policies.
