Barriers to prescribed burns

Prescribed burns can help reduce catastrophic impacts of wildfires. Miller and colleagues find that regulation, funding and human capacity are the main barriers to implement this approach more widely in California.

    Changes in social and environmental conditions in the Western Highlands of Guatemala undermine food security and job opportunities. We describe how targeted assistance can build upon traditional agricultural systems to increase adaptive capacity, improve nutrition, provide jobs and thereby reduce pressures to migrate.

    Disadvantaged communities are vulnerable to the impacts of lead exposure risking further worsening of their living standards, an outcome likely to weaken global efforts towards the Sustainable Development Goals. We urge policy makers to adopt protection systems aimed at safeguarding the most threatened populations.

    Current methods to remove oil microdroplets from wastewater are ineffective at the variable pH conditions commonly found in wastewater. This study presents a surface-engineered sponge that synergistically combines surface chemistry, charge and roughness, providing a solution to this problem.

    By passively evaporating water from waste streams, evaporation ponds work with different waste streams but need large areas due to low evaporation rates. This study shows that a photo-thermal device converting sunlight into mid-infrared radiation could enhance evaporation and reduce land needs.

    The recent shift in the United States from coal to natural gas for electric power has reduced the carbon dioxide emissions intensity of electric power production, but the other pollution-related impacts of this shift are not yet known. This study finds that, between 2005 and 2016, decommissioning coal-fired plants in the continental US saved an estimated 26,610 lives and 570 million bushels of corn, soybeans and wheat in their vicinities and also changed regional climate.
