In 2009, economist Jeffrey Sachs, alongside more than 20 eminent scholars from different fields, highlighted the importance of biodiversity for human well-being in a policy commentary published in Science. They noted the Millennium Development Goals (MDGs) included a target to achieve, by 2010, a significant reduction in the rate of species loss, and they also noted that it was one of the MDG targets that was most off-track. “Our lack of progress toward the 2010 target,” they said, “could undermine achievement of the MDGs and poverty reduction in the long term.” The 2010 target was missed, and today species are moving toward extinction at an ever faster pace. Last week’s announcement confirming the extinction of Africa’s western black rhino is the latest sad example of this trend.

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.

Pakistan, long a nation defined by its large rural populations and dominant agricultural industries, is undergoing a dramatic urban shift.

According to UN Population Division estimates, the country is urbanizing at a three percent annual rate – the fastest pace in South Asia. In barely 10 years, nearly 50 percent of Pakistan’s 180 million people will live in cities (a third do today). Pakistani government projections using density-based rather than administrative definitions of urbanization suggest that Pakistan’s urban population has already reached 50 percent.

“We knew that we had a lot of reports, we knew that we had a lot of policy papers, but what we wanted to tell was a good story,” said ECSP’s Sean Peoples speaking recently at Duke University about the short documentary, Healthy People, Healthy Environment: Integrated Development in Tanzania.

“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.

The first time Almaz, a teenager living in rural southern Ethiopia, went to the crowded health care clinic in her village to get contraception, she was told they only helped older women with children. The second time, she waited hours only to find out that her preferred method of contraception was out of stock and she would have to return another day. [Video Below]
