This document discusses assessing progress in adaptation for vulnerable groups, communities, and ecosystems. It provides examples of specific areas for consideration in National Adaptation Plans (NAPs), such as ensuring institutional arrangements and assessment frameworks address vulnerabilities. Sample processes and actions from countries like Nepal and Kenya are described. The document outlines identifying vulnerable groups and ecosystems, and developing appropriate metrics and indicators to measure adaptation progress, such as food security, health, infrastructure, and ecosystem services. An interactive session discusses applying these lessons to NAP development and implementation.
