I would also urge people to check out Karen's SAVI work, the Southern African Vulnerability Initiative that she has pursued over the years with Coleen Vogel of the University of Wits in South Africa. Although IPCC contributors themselves, they do not limit their notion of the sources of vulnerability to climate change. They explicitly recognize the importance of poverty, governance, health, food security etc in the multiple factors that go into making southern Africans vulnerable. This explicit attempt to account for complexity in research is a trademark of GECHS that runs through Karen's tenure as chair and back to Mike Brklacich and Steve Lonergan before her.
