Forecasting malaria

The study integrates climate, land use, and socioeconomic data to explain and predict malaria dynamics at the village level. The approach could inform health care practitioners and make control strategies more efficient and cost-effective.

Trawlers intermix with whale ‘supergroup’ in Southern Ocean

Scientists observed close to 1,000 fin whales foraging near Antarctica, while fishing vessels trawled for krill in their midst. Without action, such encounters are likely to become more common as this endangered species recovers and krill harvesting intensifies in the Southern Ocean.

A new chance to protect wetlands

New analysis shows the U.S. has accounted for more wetland conversion and degradation than any other country. Its findings help better explain the causes and impacts of such losses and inform protection and restoration of wetlands.

Biodiversity policy

Our health and economic stability depend on biodiversity, but our governing policies often fail to address it coherently. An analysis of the world’s second most biodiverse country highlights how policies that span sectors and actors can fit together to govern biodiversity more effectively.

Rethinking meat substitutes

Plant-based and lab-grown meat substitutes are here to stay, but are unlikely to eliminate livestock agriculture’s climate and land use impacts anytime soon, according to Stanford environmental scientist David Lobell.

Droughts increase costs for low-income households

According to a recent study, when providers act to curtail water use or invest in new infrastructure because of a drought, bills can rise for low-income households and drop for high-income households.

Top 10 sustainability research stories of 2022

The Stanford Doerr School of Sustainability looks back at the research highlights from the units that came together to form the new school, which launched in September.

COP27: How to reduce emissions and still feed the world

Stanford delegates co-hosted an event at COP27 highlighting the role cutting-edge research and solutions can play in decarbonizing the food and agricultural systems.

Solar panels largely confined to wealthy Americans

Tax rebates for installing residential solar power have done little to spur adoption in low-income communities in the United States, while a less common incentive seems to succeed, according to new research using AI and satellite images.

Dams and food security

Analysis finds that dammed reservoirs could store more than 50% of the water needed to irrigate crops without depleting water stocks or encroaching on nature. The researchers caution against building new dams, however, and urge consideration of alternative storage solutions.

Beaver dams buffer rivers against climate extremes

American beaver populations are booming in the western United States as conditions grow hotter and drier. New research shows their prolific dam building benefits river water quality so much, it outweighs the damaging influence of climate-driven droughts.

Cover crops can lower yields

Federal subsidies promote planting cover crops to store carbon in agricultural soils, among other benefits, but the approach as currently practiced can reduce yields in the U.S. Corn Belt, researchers find. Their analysis highlights the need to better implement the practice.

Climate justice

International negotiators will meet in Egypt this Sunday for the latest U.N. climate change conference. Stanford experts in a range of fields discuss issues likely to be in the spotlight, including compensation to developing countries for climate change-related damages.

Whales eat colossal amounts of microplastics

Analysis of ocean plastic pollution and whale foraging behavior tracked with noninvasive tags shows whales are ingesting tiny specks of plastic in far bigger quantities than previously thought, and nearly all of it comes from the animals they eat – not the water they gulp.

Predicting drought development using plant processes

Based on new analyses of satellite data, scientists have found that hydrologic conditions that increase flash drought risk occur more often than current models predict. The research also shows that incorporating how plants change soil structures can improve Earth system models.

Sustainable health care

The health care sector accounts for almost 10% of U.S. emissions and is one of the country’s largest producers of waste. What can be done to make it more sustainable, while maintaining safety?

Wildfire smoke exposure hurts learning outcomes

Pollution from wildfires is linked to lower test scores and possibly lower future earnings for kids growing up with more smoke days at school, a new study finds. Impacts of smoke exposure on earnings are disproportionately borne by economically disadvantaged communities of color.

Empowering private landowners to prevent wildfires

Controlled burning has proven effective at reducing wildfire risks, but a lack of insurance has dissuaded private landowners from implementing the practice. Policy expert Michael Wara discusses soon-to-be-enacted legislation that would pay for fire damages to neighboring properties in California.

Wildfire smoke is unraveling decades of air quality gains

Stanford researchers have developed an AI model for predicting dangerous particle pollution to help track the American West’s rapidly worsening wildfire smoke. The detailed results show millions of Americans are routinely exposed to pollution at levels rarely seen just a decade ago.

Healthy rivers, healthy people

Analysis reveals how restoring relatively narrow forest buffers could substantially improve regional water quality and carbon storage in Costa Rica and elsewhere. Such changes could have outsized benefits for vulnerable populations that rely on rivers for their water supply.

New ‘lab on a chip’ may accelerate carbon storage efforts

A tiny new device allows scientists to directly observe and quantify how rocks change in the presence of acids, enabling more accurate assessments of sites for underground storage of carbon dioxide, hydrogen, and industrial waste.

Geological activity can rapidly change deep microbial communities

New research reveals that, rather than being influenced only by environmental conditions, deep subsurface microbial communities can transform because of geological movements. The findings advance our understanding of subsurface microorganisms, which comprise up to half of all living material on the planet.

Four questions for Liz Hadly

The Stanford environmental biologist and global change specialist discusses recent flooding in Yellowstone National Park – and what it means for the future of the planet.

Children’s health and climate change

Children are more likely than adults to suffer health impacts due to environmental impacts. Kari Nadeau of Stanford’s Sean N. Parker Center for Allergy & Asthma Research discusses related risks, as well as what caregivers and health care workers can do about them.
