The Amazon, home to rich biodiversity and vital carbon-storing ecosystems, is also the ancestral land of Indigenous communities who are grappling with the devastating effects of oil extraction across Ecuador, Peru, and Colombia. These communities live amid widespread pollution from oil spills, toxic chemicals, and industrial infrastructure, which threaten their way of life and the health of their environment. In response, they are working alongside researchers to map the environmental destruction and strengthen their efforts to hold oil companies accountable while fighting to protect their lands and preserve their cultural heritage.

Heat significantly affects pregnant women and infants, increasing risks like dehydration, heat exhaustion, and developmental issues in children. Expectant mothers are more vulnerable due to physiological changes, while infants face heightened danger because of immature temperature regulation. These challenges are further intensified for families with limited resources. Researchers are investigating these impacts to provide lawmakers with the knowledge needed to create protective measures for these at-risk groups.

Cooling is energy-intensive, with air conditioning consuming a significant portion of electricity in homes and commercial buildings, while also contributing to greenhouse gas emissions and climate change. This creates a cycle of increasing energy demand for cooling. However, innovative materials that cool when strained offer a promising, sustainable solution for various applications.

Nitrous oxide is a potent greenhouse gas with nearly 300 times the warming potential of carbon dioxide, making even small emissions highly impactful. Agriculture, particularly soil management, is the largest source of nitrous oxide. To better understand and manage these emissions, researchers have developed a system for continuous monitoring on farms and other land management purposes.

PFAS, synthetic chemicals found in countless everyday products, have made their way into humans and animals around the globe. Although their health effects remain unclear, their widespread presence raises important questions. Scientists are now investigating whether these chemicals might disrupt the human gut microbiome, potentially impacting our health in unexpected ways.

The Earth can shift suddenly, with sinkholes and landslides posing serious risks to people and property. Scientists are now using existing fiber optic cables in cities to detect potential geohazards before they strike. This innovative approach is expanding to monitor flooding and even track human movement, unlocking new possibilities for data collection and understanding our world.

Cement, a major component of concrete, is a significant contributor to global carbon emissions. Researchers are exploring agricultural waste as a potential alternative to cement, aiming to reduce carbon footprint while also finding new uses for farm byproducts. However, the feasibility and effectiveness of this solution depend on the collaboration between researchers and farming communities.

Smallholder farmers are the unsung heroes of our food system. Tilling tiny plots, they produce a staggering one-third of the world’s food and up to 80% of the food supply in regions like sub-Saharan Africa and Asia. But these vital contributors face immense challenges: such as climate change, pests, insufficient finances, and limited education and training. On this episode of Growing Impact, we’re revisiting the story of PlantVillage, a project funded as a seed grant by IEE in 2016. Its aim was to empower smallholder farmers with knowledge through smartphones and machine learning. Since its creation, PlantVillage has gained strong support from organizations worldwide and has built a robust team of partners and collaborators. Looking ahead, PlantVillage plans to expand how it’s helping farmers while simultaneously addressing climate change. 

Flooding is the world's most devastating natural disaster, causing widespread destruction and loss of life. Millions of Americans live in high-risk flood zones, with the threat amplified by climate change and aging infrastructure. This episode explores how innovative computer modeling and visualizations can help communities plan for future flood risks and develop effective response strategies.

Carbon dioxide (CO2) is abundant and stable, making it difficult to convert into something useful without a lot of energy. Researchers are using advanced computational modeling to find a catalyst that can efficiently transform CO2 into valuable products. This could turn CO2 from a climate issue into a valuable resource.
