In March, the Intergovernmental Panel on Climate Change released its latest comprehensive synthesis of climate change research. The report concludes that “impacts from recent climate-related extremes, such as heat waves, droughts, floods, cyclones, and wildfires, reveal significant vulnerability and exposure of some ecosystems and many human systems to current climate variability.”

World Population Day began in 1987 after public imagination was sparked by the idea that there could be 5 billion people on Earth. Today, we’re well past 7 billion and according to the latest UN projections, headed north of 9 billion by mid-century.

“Population is critical to thinking about sustainability and human wellbeing, and how we live and subsist on the planet,” says ECSP’s Roger-Mark De Souza on this World Population Day.

My grandmother was pleased when I told her I was heading to Ethiopia last November for an international conference focused on population, health, and the environment.

The May edition of Reproductive Health Matters is a special edition on sustainable development and reproductive health and rights. Our own Roger-Mark De Souza writes that in the quest to build resilience, development practitioners can learn from integrated population, health, and environment (PHE) programs.

Despite the threat posed by flooding and sea-level rise, relatively little attention has been paid to the potential for environmentally induced instability in coastal West African cities. However, current trends, including rapid population growth, land use patterns, and increasing climate impacts, suggest the costs of inaction in these urban areas are rising.

Rapid growth and environmental change are creating new challenges for urban areas around the world. By 2050, as many as 7 out of 10 people on Earth will live in cities, with the vast majority of growth occurring in today’s developing countries. [Video Below]
