Resilience is a wonderful metaphor. It somehow conveys in a single word the qualities of bending without breaking, of healing after an injury, of tensile rather than brittle strength. Oak and palm trees are resilient to the power of strong winds, before which they bend and then straighten again. Resilient people pick themselves up after being knocked down, draw on their reserves of ideas and strength to deal with difficult challenges, or hunker down until the gale has blown itself away. Resilient economies bounce back, and resilient ecosystems restore themselves after the fire or the flood has passed.

The disempowerment of women and girls is the single biggest driver of inequality today, said Helen Clark, administrator of the UN Development Program, during a plenary on the final day here at the Women Deliver conference in Kuala Lumpur, where more than 4,500 people from 149 countries and 2,200 organizations gathered to discuss women’s health, equity, and international development.

Climate-induced migration in Mexico is a complex issue and the future impact of this phenomenon is neither clear nor agreed upon. The Environment, Conflict and Cooperation (ECC) team talked to Elizabeth Deheza from the Royal United Services Institute for Defense and Security Studies. She and Jorge Mora are the authors of the recent study “Climate Change, Migration and Security: Best-Practice Policy and Operational Options for Mexico.”

Amid the growing number of reports warning that climate change could threaten national security, another potentially dangerous – but counterintuitive – dimension has been largely ignored. Could efforts to reduce our carbon footprint and lower our vulnerability to climate change inadvertently exacerbate existing conflicts – or create new ones?

Natural disasters have dominated news coverage in the past several years, with many observers noting a distressing rise in the frequency and scale of disasters as well as rising costs. Despite these worrying trends, a critical mass of leadership and public support for doing something about it is emerging.
