As the summer sea ice melts in the Arctic, polar bears struggling to hunt seals are increasingly turning to sea-birds for food. New scientific research suggests that this change in the polar bear diet could severely reduce sea ducks populations and deprive Arctic peoples of a major source of food and livelihood.
Non-timber forest products from urban areas are often overlooked as a viable source of income for impoverished communities. A new study investigates whether or not these products help households in South Africa stay out of poverty.
The advocacy campaigns #SavetheAmazon and #SavetheRainforest are known the world over, but do we have it backwards? A team of researchers and doctors suggest that, actually, the Amazon rainforest could save us.
The stories about the poaching of African elephants are deeply imbedded in the carbon isotope tracers that make up the prized tusks. A group of scientists used these tracers to uncover the realities of poaching activities threatening Africa’s elephants today.
People give meaning to urban parks and cities in different ways, an inherently political process that opens up some possibilities while foreclosing others. Once seen as refuges from the city, urban parks have been reimagined as economic drivers, a shift that fits into a larger process of neoliberalism.
Drought has become increasingly prevalent in many parts of the world, but how it will affect ecosystems is often poorly understood. In the Yellow River Delta scientists discovered that another factor, natural enemies, hinder the ability of plants to recover from drought.
Human land-use is a primary cause of biodiversity loss. A recent study shows that human changes to ecosystems has pushed global biodiversity loss beyond safe limits, which could reduce nature’s resilience.
A mathematical model has been constructed to analyze the effect of Beijing’s odd-and-even license plate rule. The results concur with previous studies: it works somewhat in the short-term, but inadequate in the long run.
A recent study analyzes how collective action can influence community resilience to flood hazards. It highlights several key interactions between human populations and the water systems they depend on.
Why are people so stubborn in their beliefs? Why do people, when confronted with someone who disagrees with them, so often double-down in their arguments? A Yale scientist may have some answers — with surprising findings on who are the worst culprits.
To grow or not to grow? That is not the question. Policymakers are unconsciously limited in their choices regarding climate policy by the conventional expectation to achieve economic growth. In a recent article, a researcher examines different perspectives on growth-versus-climate debate and points out a way forward.
We have entered an era where humans have had a profound impact on the planet. In this new world that we have created, what species will endure and what others shall perish? How can we predict what species they will be?
More than 83 percent of chemicals have no safety information. Most businesses don’t design them for safety, and the government doesn’t test most of them for safety. Yet thousands of chemicals are in our water and soil, potentially causing human harm and costing billions to cleanup. How can we tell if new chemicals will cause damage to humans before they are made?
Maple sugar is the most important non-timber forest product in the northeastern U.S. A new study shows greater amounts of nitrogen in the soil can lead to sweeter sap and therefore higher maple sugar yields.
While much research has pointed to a steady decline of the Sumatran orangutan as a consequence of habitat loss, a recent study shows population estimates are higher than previously thought. Are these higher estimates enough to preserve the species?
A recent study showed empirical evidence of a turning point of Indonesia CO2 emissions. According to the findings, CO2 emissions will start to decline as income per capita reaches around $8,000, with profound implication Indonesian energy policy.
As one of the largest and arguable strongest economies on the African continent, South Africa has not shown the kind of leadership on renewable energy as might be expected, a group of researchers says.
The world has long attributed Tibetan wisdom to the Buddhist monks and their teachings, but largely ignored the wisdom of the nomads. Recently, scientists have proven that traditional grazing practiced by these nomads are crucial for Tibetan rangelands, promoting plant diversity and nectar production.
In a recent study, a team of scientists was able to show how places like Norfolk, Va. will experience more flooding and coastal erosion than ever before — not only during hurricanes like Sandy and Isabel, but more frequently during typical rain and wind events.
