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.”

Earlier this week, the Department of Defense released its first Quadrennial Defense Review since fiscal cliffs, shutdowns, and spending cuts hit the federal government. Not surprisingly, “austerity” shows up in almost every chapter of the report. What shows up even more? Climate change. For the second QDR in a row, the Pentagon has called out climate change as a “significant challenge for the United States and the world at large.”

In the sleepy northern Thai border town of Huay Luk, a community leader, Pornsawan Boontun, still remembers the day when villagers netted a Mekong giant catfish more than a decade ago. The fish weighed 615 pounds, and it surprised everyone since the elusive species has never been common in this stretch of river.

Factories in China’s Pearl River Delta tick-tock around the clock, rapidly churning out gadgets from iPhones and Barbie dolls to forks and light bulbs, shipped off to village shops in Uganda and super Walmarts in America’s sprawling suburbs. But far from the global consumer’s view, manufacturing and rapid development are placing unrelenting pressure on China’s environment.

A 20-year peace accord between Mozambique’s two major political parties was brought to an abrupt end last fall. A series of violent skirmishes between FRELIMO and RENAMO resulted in at least 10 deaths, dozens injured, and fears that the country might relapse into the kind of political violence seen during its civil war, which left more than a million dead. RENAMO claims its frustrations stem from a fraudulent electoral system and social inequality, but some observers have suggested their motivations may be less benevolent: making sure they get their piece of the country’s newfound natural gas wealth.

2014 promises to be a superlative year – and that’s not necessarily a good thing. Complex, “super” disasters like Super Typhoon Haiyan are becoming more frequent, more systemic, and more destructive. Global trends, from population dynamics to food, water, and energy scarcities, threaten to further complicate the playing field. But by finally getting serious about resilience – the much discussed buzzword of 2013 – we might reduce our vulnerability, restore our communities, and build back better, rather than just picking up the pieces.

We made the crossing at night from Chamoli, reaching Okund, a Himalayan foothill town after dark. The innkeeper, anxious for guests in a travel economy that came to a standstill in mid-June, cooked dal and nan bread for dinner and then showed us to a room that was unlit and unheated.
