Efforts of developing countries in assessing and meeting the costs of adaptation: Lessons learned and good practices

Resource Description

This resource examines how developing countries assess and address the costs of climate adaptation, drawing on national plans, communications, and case studies

Why This Matters

A clear understanding of adaptation costs supports more effective planning, budgeting, and access to finance for climate-resilient development.

Key Insights

  • Countries use national and sector-level cost estimates, led by planning or environment ministries, and increasingly integrate these into budgets
  • Costing methods include macroeconomic models and project-level estimates, though data and capacity gaps persist
  • Reported adaptation costs range from 15% to 45% of GDP annually in some countries
  • NAPs and adaptation communications are key tools for accessing international climate finance
  • Highlights need for capacity building in data, methodologies, and institutional collaboration
