The Paris Agreement requires Parties to prepare, communicate, and maintain successive Nationally Determined Contributions. Bangladesh, Nepal, and Sri Lanka have submitted their NDCs with different sectors covering mitigation, adaptation, and loss and damage. However, these three countries face different gaps and needs for the implementation of these commitments, such as those related to laws and policies, institutional and technical capacity, or means of implementation. This research identifies gaps and needs for the implementation of adaptation and loss and damage components of NDCs in Bangladesh, Nepal, and Sri Lanka as the result of legal and policy analysis, expert interviews, small group consultations, and national and regional multi-stakeholder workshops.
