Sri Lanka is highly vulnerable to climate risks, with heat, sea level rise, floods, landslides, and droughts posing significant threats to its ecosystems, economy, and communities. Local drivers such as pollution and land management exacerbate these risks, impacting agriculture and food production, cities and infrastructure, water availability, local biodiversity, and human health and well-being. With 80% of the population vulnerable and lacking adaptive capacity, Sri Lanka is projected to experience a 3.86% reduction in GDP by 2050. To build resilience, the country requires substantial investments – $36.5 billion by 2030 and $54.2 billion by 2050. This document consolidates key datapoints on climate risks its socio-economic and environmental impacts, offering a useful source of reference for diverse stakeholders such as financial institutions, policymakers, businesses, researchers, and practitioners.
