“Women and men face very different risks and challenges,” said Chitra Nagarajan, a writer and journalist who covers climate change, conflict, and gender. She spoke in this week’s podcast about what’s changed in the Lake Chad region. In the last few years the combination of profound climate change and high levels of insecurity have made life harder for the local population. To get a sense of how recent changes have affected Lake Chad’s residents, Nagarajan interviewed more than 250 people. These are some of her findings.

“I believe if you acknowledge women as primary users of environmental resources, if you draft the policy with women [at] the table, offering you their unique perspective and unique feedback, you’re going to have a more stable policy. A policy that gets implemented,” says Mishkat Al-Moumin, scholar in residence at the Environmental Law Institute, in this week’s Friday Podcast, and second in a series of interviews recorded at the First International Conference on Environmental Peacebuilding.

United States and China are on the road to war, said Senior Advisor of New America’s Resource Security Program, Sharon Burke in this week’s Friday Podcast. “And if you’re an environmental peacebuilder and you’re not thinking about that, you might want to,” she added. She spoke with Geoffrey Dabelko, Professor at Ohio University and Senior Advisor to ECSP, at the first ever International Conference on Environmental Peacebuilding in October 2019 at the University of California, Irvine. It’s a war we can’t afford, said Burke. “But we’re not doing anything to avoid it at the moment, in my opinion, other than deterrence.”

For some time, it has been clear that a global population imbalance is emerging. High income countries, including nearly all of the Americas, Europe, and most of East and parts of South and Southeast Asia, have seen a dramatic, sustained fall in fertility. Already, this is resulting in shrinking labor forces and the oldest mean age populations seen in history. At the same time, the low income countries and even some lower middle-income countries—mainly in Africa but also in Central America, the Middle East, and parts of South and Southeast Asia—continue to have relatively high fertility. This is now, and even more in the coming decades, producing fast-growing labor forces and relatively young populations.
