The new year promises some big changes for the field of environmental security—and some big moves for the Environmental Change and Security Program (ECSP). As we say hello to 2018, we wave goodbye to Roger-Mark De Souza, and welcome him to our team of advisors and fellows. And I’m excited (if a bit daunted) to step into his shoes as our Acting Director and tackle the challenges to come.

This new year brings new projects—and some sad goodbyes. Today, I’m excited to begin my leadership of Sister Cities International, the world’s largest and oldest network of citizen diplomats. And I’m sorry to leave the Wilson Center, which has been my home for the last five years. But it’s not a long goodbye: I will continue to work with the Global Sustainability and Resilience team as a Global Fellow and as an advisor to the New Security Beat. In all of these roles, my New Year’s resolution is to renew our commitment to making a real difference in global well-being and sustainability. And while this year promises great changes, three key priorities will continue to inspire me and guide our collective efforts: resilience, complexity, and diplomacy.
