When Super Typhoon Haiyan ripped through the Philippines last month, the incredible damage visited on the people, infrastructure, and land was shaped by trends that have been in motion for decades. The country’s population has been growing rapidly, with high concentrations of people living in cities and along the coast; economic growth had been steady, but weak governance and corruption may have exacerbated vulnerability; and the gradual loss of coastal forests and mangroves left many communities exposed to the full brunt of the typhoon’s storm surge. On a positive note, wireless technology and crowd-sourced data helped in disaster response.

When Cyclone Haruna swept across Madagascar last February, Blue Ventures, a marine conservation and community health organization, found themselves in a surprising new role. “We went from development, to aid, and back to development, in an integrated way we never expected,” said Medical Director Vik Mohan in an interview at the Wilson Center.

The effects of climate change are often conveyed through the lens of changing physical landscapes. Shifting weather patterns, the intensification of drought, flooding, and coastal erosion are all primary areas of climate research. But do researchers know enough about changes in the size, distribution, and composition of human populations as they relate to climate vulnerability? [Video Below]

When it comes to climate change vulnerability, it sometimes seems as if all eyes are on Bangladesh. As part of my research for a recent article exploring the rise of aquaculture in the country, I interviewed Saleemul Huq, senior fellow at the International Institute for Environment and Development in London, former executive director of the Bangladesh Center for Advanced Studies, and lead author of two chapters on adaptation and sustainable development in the IPCC’s third and fourth assessment reports. A number of his quotes made it into the final story but I wanted to provide the full transcript here as well, as his thoughts on the country’s climate-related risks, food security, and population dynamics are worth a read.

“The size and growth of the human population is putting unprecedented pressure on natural resources,” reports the first major publication by the Global Partnership for Oceans. The World Bank launched the consortium of more than 140 government, NGO, and private sector groups at the Rio+20 UN Conference on Sustainable Development as a means to bring targeted investment to reverse ocean health decline and encourage sustainable development. On October 16, the Partnership’s Blue Ribbon Panel released Indispensable Ocean: Aligning Ocean Health and Human Well-Being, which encourages members to prioritize five principles: sustainable livelihoods, social equity, and food security; a healthy ocean; effective governance systems; long-term viability; and capacity building and innovation. Selection criteria for investments accompany each principle, including requirements like addressing problems of food affordability and access, demonstrating potential for improvements in human health, and building resilience to future conditions. “The good news is that we stand at a point in history where it is neither too late nor impossible to turn the tide of change that is currently sweeping across the ocean,” panel chair Ove Hoegh-Guldberg concludes.
