For years, the Chepang people have lived off the land in Nepal’s forested central foothills. Communities cleared trees to start small subsistence farms, harvested the surrounding area for firewood, and eventually moved on after the wood, soil, and water were depleted.

It was a scorching hot April afternoon in Keur Moussa, a small farming community about 60 kilometers outside Dakar, Senegal. The landscape was mostly barren and very dry, and a fine red dust settled into our clothes as we walked with community leaders to learn about their efforts to cope with a changing environment. In this part of the world, adapting to climate change is figuring out how to manage water: how to survive for long periods without it, and what to do when too much comes at unexpected times.

While climate change has enjoyed a recent spike in news coverage, journalists face a constant challenge to bring sustained attention to other environmental stories, including resource scarcity, the changing oceans, and demographic change. [Video Below]

What are the environmental implications of changing household sizes? A recent article by Mason Bradbury, M. Nils Peterson, and Jianguo Liu, published in Population and Environment, analyzes data from 213 countries over 400 years and finds the average number of occupants per home tends to decline as population grows. This dynamic, they write, indicates that accommodating housing could prove to be one of “the greatest environmental challenges of the twenty-first century.” As countries develop and urbanize, “according to convergence theory, household size decreases (often from greater than five to less than three).” Other cultural shifts, like increasing divorce rates, urban sprawl driven by rising affluence, decreasing numbers of multigenerational households, and larger houses (in the United States, homes more than doubled in size between 1950 and 2002, according to the article) compound the issue. As population growth continues in parts of the world, these trends pose critical questions for conservation and environmental sustainability, since “households are the end consumers of most natural resources and ecosystem services.”

I meet Keo Mao, 42, in the floating fishing village of Akol on Cambodia’s Lake Tonle Sap. The houses here move seasonally with the lake, which expands by a factor of five during the monsoon rains and recedes again in the dry months. Fish supply about 80 percent of the animal protein eaten by Cambodians, and about 60 percent of the inland catch comes from the Tonle Sap.

In Lake Victoria and Lake Chilwa basins, interconnected development challenges defy sectoral boundaries, said experts at the Wilson Center on February 10. According to Deepa Pullanikkatil of Leadership for Environment and Development and Doreen Othero of the Lake Victoria Basin Commission, growing populations, shrinking resource bases, and persistent human health concerns demonstrate the need for integrated development approaches that combine population, health, and environmental (PHE) interventions. “We need different sectors working together to achieve the greater goal,” said Pullanikkatil. [Video Below]

Pakistan is at a crossroads, and not for the reasons you might think.
