Introduction: Coastal zones of Sri Lanka are highly vulnerable to the impacts of climate change, including sea level rise, extreme weather events, and coastal erosion. The Paris Agreement, Sustainable Development Goals (SDGs), and Sendai Framework emphasize the importance of coastal climate adaptation and risk reduction strategies, such as risk-sensitive development planning, early warning systems, and community engagement. Policy gaps and needs assessments are crucial for implementing adaptation and loss and damage measures in the context of the National Adaptation Plan. Objectives: This study aims to review the challenges faced by Sri Lanka in implementing the global agendas of the Paris Agreement, SDGs, and Sendai Framework and provide recommendations to assist policymakers and stakeholders in advancing these goals. Methodology: A comprehensive literature review approach was employed, utilizing country reports as the primary source of information. The literature review allowed for an analysis of challenges and progress in implementing the global agendas in Sri Lanka. Findings: Sri Lanka has integrated these three global agendas into its climate change adaptation policies and initiatives, but significant obstacles to implementation remain. Limited availability of climate and socio-economic data hampers planning and decision-making processes, and inadequate climate-related regulations and standards hinder the effective implementation of adaptation measures. Improved collaboration and coordination among stakeholders and adequate financial and technical resources are essential to achieve the integrated approach required by these global goals. Sri Lanka has progressed towards these global climate change agendas, but implementation challenges persist. Adaption projects should address local phenomena, and an integrated approach to the three agendas is vital. Sri Lanka must fulfil its commitments to ensure a sustainable future. Conclusion: Sri Lanka has proactively aligned its climate change adaptation policies and initiatives with three global agendas: the Paris Agreement, SDGs, and Sendai Framework. In order to foster a sustainable and climate-resilient future. These efforts include addressing data shortages, enhancing regulations, improving coordination, and forging international partnerships to draw upon global expertise to address unique challenges in the coastal region of Sri Lanka.
