Experts agreement on key elements of transformational adaptation to climate risks

Experts rated the relevance of a few additional elements that were suggested by multiple experts in round one. In the third round experts evaluated two definitional statements derived from earlier responses. The Delphi panel comprised n=99 participants in Round1, n=64 in Round2, and n=52 in Round3.

In Round1, participants included researchers (n=26), practitioners (n=27), mixed profiles (n=28), and those who preferred not to answer (n=18); the distribution was similar in subsequent rounds (Round2: n= 17, 17, 18, 12; Round3: n=15, 13, 15, 9). Regional foci were diverse, including Africa (Round2: n=10; Round3: n=7), the Americas (n=7; n=5), Asia/Middle East (n=5; n=4), Europe (n=12; n=10), and Oceania (n=4; n=3), while many reported no specific regional focus (n=24; n=21).

Participants worked across multiple administrative levels, most commonly national (n=38; n=31) and local (n=43; n=34), followed by province (n=28; n=24), community (n=29; n=22), global (n=27; n=21), and regional (n=20; n=17).
