Dams in the Mekong Basin are built without considering impacts on river processes. This study shows that with strategic planning in the lower Mekong, 68% of the basin’s hydropower potential could have been developed while trapping 21% of the basin’s sand load.
Achieving a high quality of life within the biophysical limits of the planet is a significant challenge. This study quantifies the resource use associated with meeting basic human needs, compares it to downscaled planetary boundaries for over 150 nations and finds that no country meets its citizens’ basic needs sustainably.
A two-wave survey focused on 21 actions shows that the anticipation of a ‘feel-good’ effect is positively associated with proenvironmental behaviours over a four-week period. This association is found to be stronger for low-cost green choices.
Choosing products like recycled water, artificial meat and insect-based food is hindered by the disgust they elicit. This study finds that using a foreign language to describe such products can increase both their intended and actual consumption.
A balanced diet is vital for human health, and the Sustainable Development Goals codify this aim. This study finds that trade helps ensure the equitable distribution of food nutrients globally, with implications for international trade policies.
Rising population and changes in water supply under climate change affect cities globally. This study finds that in 27% of cities studied, water demand is likely to exceed availability by 2050, with many other cities competing with agriculture on water needs.
Little is known about the water impacts of concrete production. This study quantifies this impact globally for 2012 and projects it to 2050. It also evaluates in which regions the impacts will be more severe, based on the availability of renewable water resources.
After developing a unit-based air pollutants emission inventory of more than 30,000 fossil fuel power plants operating worldwide in 2010, the authors find that retiring or implementing controlling measures on coal-fired power plants, representing 0.8% of global capacity, could reduce PM2.5 emissions from coal-fired plants by up to 14.2%.
Since 2000, China has attempted to vegetate huge portions of eroded landscape in its south west, bordering Vietman, Laos, and Myanmar. This study finds that this ecological engineering is combating desertification as vegetation regrows and stores carbon.
Post-disaster reconstruction in hazard-exposed areas can increase social vulnerability if a disaster changes where people wish to live. In a post-tsunami zone in Indonesia, the authors find that many people wish to move to safer areas, causing housing prices to go up inland and the poor to live near the coast.
