Maps help us to grasp complex ideas, such as patterns of risk and vulnerability, but the stories they tell can have significant implications. “It’s very difficult to validate that what you’re capturing in the maps is representative of real-world phenomenon,” says Joshua Busby in this week’s “Backdraft” episode, describing his efforts to map climate and security hotspots in Africa and Asia. “You have to be modest in what you think the maps can tell policymakers, but also realize there is some seductive power in the way maps simplify complex reality.”

When the Paris Agreement set an ambitious goal of limiting the global temperature rise to 1.5 degrees Celsius above pre-industrial levels, the negotiators put climate engineering on the table, says Simon Nicholson, professor at American University, in this week’s episode of Backdraft. Once the purview of science fiction, a majority of the models run by the Intergovernmental Panel on Climate Change (IPCC) required large-scale use of climate engineering technologies to keep additional warming below 2 degrees.

As more and more development and humanitarian programs contend with climate-related problems, there are important lessons learned from past experience that should not be forgotten, says Janani Vivekananda, formerly of International Alert and now with adelphi, in this week’s episode of “Backdraft.”

In a research project spanning more than two dozen case studies on environmental governance in 13 sub-Saharan African countries, Jesse Ribot, professor at the University of Illinois, and colleagues found that while many forest management projects claimed to be working with communities, they were in fact undermining local democracy in various ways.

In international development, conflict is often used as shorthand for violent conflict, and avoiding conflict is considered a priority. But “it’s important to recognize that conflict is not always bad and cooperation is not always good,” says Ken Conca in this week’s episode of “Backdraft.”
