Exploring What We Can't See

In business, it's essential to understand the factors influencing your industry. The world's oceans drive multi-billion-dollar fishing and tourism economies, but we have explored only about three percent of the deep sea, according to Woods Senior Fellow Rob Dunbar (Environmental Earth System Science), who spoke at a recent Stanford+Connects event. A team led by Senior Fellow Stephen Monismith (Civil and Environmental Engineering) discovered that voluminous underwater waves known as "internal bores" can potentially have a dramatic impact on marine productivity, affecting the abundance and distribution of a variety of organisms such as crabs, abalone, clams and octopi. This research in California's Monterey Bay grew out of a 2009 Environmental Venture Project, and is part of ongoing work at Stanford's Hopkins Marine Station aimed at clarifying the impact that internal bores have on the ecosystem as a whole.

Aiding Adaptation to Snowpack Changes

Snowpack – vital for water storage, food, and energy supplies - is expected to decline by the end of the century. Yet some places could see snow increases over the next 50 years, complicating adaptation responses. A study co-authored by Justin Mankin, a graduate student in the Emmett Interdisciplinary Program in Environment & Resources in the School of Earth Sciences and Woods Senior Fellow Noah Diffenbaugh (Environmental Earth System Science) shows that such uncertainty, when considered in predictive modeling, can affect expected changes in snow accumulation at local scales relevant to decision-making.

Ecosystem Services

Using Science to Open Way to "Blue Economy"

Scientists at the Natural Capital Project recently shared new science and open source software that can calculate risk to coastal and marine ecosystems. These novel tools were used to design the first integrated coastal zone management plan for the Caribbean country of Belize.

Food Security

Urban Agriculture on the Rise

Food production globally is taking on an increasingly urban flavor, according to a new study that finds 456 million hectares—an area about the size of the European Union—is under cultivation in and around the world's cities. The paper, co-authored by Woods Senior Fellow Eric Lambin (Environmental Earth System Science), challenges the rural orientation of most agriculture research and development work.

Fresh Water

The Future of Water Vulnerability

In the years ahead, growing populations will strain large cities' ability to provide sufficient water. Among the findings of a global analysis of urban water supply vulnerability: reservoirs and other constructed water storage may provide only tenuous water security. The study, co-authored by Woods-affiliated postdoctoral scholar Julie Padowski (Global Freshwater Initiative) and Senior Fellow Steven Gorelick (Environmental Earth System Science), suggests solutions for some cities, including reallocating water by reducing environmental flows and transferring water from irrigated agriculture.

Oceans

Falling Through The Cracks: Story of the Sawfish

To find a missing fish, you have to go back through time. Using statistics, historical documents, images and even museum specimens, scientists, including Senior Fellow Fiorenza Micheli (Hopkins Marine Station), recreated history in the Mediterranean to find ways to restore the region's populations of sawfish, a globally endangered shark-like ray characterized by a long, toothed snout. The study opens the possibility of sawfish restoration in new areas, and of using historical records to inform other conservation efforts.

Public Health

Sunny With a Chance of Gastroenteritis

An analysis co-authored by Senior Fellow Alexandria Boehm (Civil and Environmental Engineering) shows that relatively easy-to-use predictive modeling systems offer a "vast improvement" over current coastal water monitoring methods. If implemented, these "nowcast" predictions could give beachgoers a better chance to avoid waterborne ailments such as gastroenteritis, respiratory illness, skin rashes and ear, nose and throat infections.

Sustainable Development

Toward More Sustainable Construction

Imagine a home construction project that replaces petroleum-based plastics, wood and engineered-wood materials with biodegradable materials. It's possible with naturally occurring biopolymers, used in wood–polymer composites (WPCs). These materials haven't gained widespread acceptance, however, because of long-term durability concerns. Researchers including Senior Fellow Sarah Billington (Civil and Environmental Engineering) and Woods-affiliated Assistant Professor of Civil and Environmental Engineering Mike Lepech developed a durability-based service-life model that simulates in-situ environmental exposure conditions, moisture diffusion, and mechanical degradation of conventional and fully biorenewable WPCs. They used the results to develop material comparison charts that simultaneously consider environmental impact and long-term, in-service performance.
