A new study finds that even with very modest precipitation changes, water supplies in the upper Colorado River basin could significantly decline by 2100, with severe consequences for agriculture, urban supplies, and ecosystem health.
The Colorado River is widely considered the most important source of water in the western United States, providing water to 30 million people and large agricultural regions and generating 8 billion kilowatt hours of hydroelectric power annually.
Many previous studies have debated whether climate change will bring a wetter or drier future to the Colorado. In this paper, Researchers Darren Ficklin (now Indiana University), Iris Stewart (ESS) and Ed Maurer (CE) used the projections from established global climate models as input to a hydrologic model to forecast what is likely to happen to water flow and other hydrologic measures, such as evaporation and transpiration on a fine scale. Their findings show that the effects of highly likely warmer temperatures will be more important than either modest precipitation increases or decreases. Thus, even if the Colorado Basin will receive some more rain and snow in the future, warmer temperatures are forecast to lead to overall less water availability due to higher evaporation rates and a lot less snow that is melting earlier in the year. In addition, the higher evaporation could mean that soils in the basin will be dryer on average, such that the lower regions of the basin turn from semi-arid to arid conditions by the end of the century.

Funding for this work was provided by the US EPA under a STAR (Science to Achieve Results) Grant.

ESS faculty member Leslie Gray's (with co-author Brian Dowd) newly published paper examines how liberalization reforms in Burkina Faso’s cotton sector have led to socio-economic differentiation. This research helps us understand the differences among Africa farmers, particularly with respect to their access to land, inputs and broader social institutions and networks. In particular, new grower cooperatives have become a site for wealthier farmers to exert influence on how debts are repaid and inputs distributed, largely to the detriment of poorer producers.

Land managers have long fought plant invasions in wildlands because invaders can harm native biodiversity, choking out native species and reducing habitat quality for animal species. But a recent paper in Bioscience, co-authored by ESS assistant professor Virginia Matzek, argues that land managers should be focusing more on invaders that have impacts on ecosystem services, the natural benefits that intact, functioning ecosystems provide to humans. For instance, some plant invaders are water hogs, depleting water that could otherwise go to irrigation; others impede navigation in streams or decrease salmon runs.
The Bioscience paper proposes that broadening the focus of management efforts to include impacts on ecosystem services may also improve the funding situation for invasive plan management, which has suffered under the recent economic decline. Currently, innovative payment for ecosystem services schemes are being developed to link natural resource management with benefits to stakeholders and users, and weed management, if linked to ecosystem service provision, could fit well into these new approaches.

A new article in the journal Frontiers in Ecology and the Environment reviews the threats that climate change poses to ecosystem services and human well-being in the United States.
Ecosystem services are the processes, materials, and commodities delivered by intact ecosystems that have value to human beings. These include crop pollination by native insects, flood protection on undeveloped floodplains, and recreation opportunities in natural areas.
Climate change is projected to hamper the availability of these services. For instance, increasingly stormy weather and rising sea levels may threaten losses to coastal property that exceed the value of development; increased drought will impact the supply and quality of drinking water sources; and lower snowfall will shorten ski seasons and decrease tourism revenues in mountain states.
SCU researcher Peter Kareiva, who is also chief scientist of The Nature Conservancy, contributed to the review, as did Virginia Matzek, assistant professor of Environmental Studies and Sciences at the university.
The article is part of a special issue of the journal reviewing the impacts of climate change in the U.S., which grew out of the U.S. National Climate Assessment, a periodic effort by the federal government to study climate change and inform appropriate government responses.

John Farnsworth has been awarded a Santander Foundation grant of £2000 to support his doctoral research. In June, Farnsworth will use the funds to travel to the Sierra San Pedro Martyr in northern Baja with colleagues from the San Diego Zoo to participate in the release of California Condors. The narrative of this project will comprise the penultimate chapter in Farnsworth's forthcoming book about Baja natural history.
The Condor Field Station is situated in a remote section of the Sierra San Pedro National Park that has been set aside for conservation research. Located in a conifer forest at nearly 8,000 feet, the research station is not accessible by car and generates its own power via solar arrays. There are currently 30 condors resident in the nearby mountains, and every year another 4 to 7 condors that have been captive-bred in the San Diego Zoo are released there.
Farnsworth, who is a volunteer with the Golden Gate Raptor Observatory's Hawkwatch program, has been studying condor literature intensely for the past several months ever since he was selected for the release team. Upon hearing news of the Santander fellowship, Farnsworth responded, "I am grateful to the Santander Foundation for their support; it will be a great honor to participate in the work of the SDZ Global Wildlife Conservancy, and to do my part to advance their mission of bringing species back from the brink of extinction."
Farnsworth directs the Baja Studies Abroad here at Santa Clara University. He spent the month of August at a field station in Bahia de los Angeles writing about ecologies of summer. He will lead the Seventh Annual SCU Expedition to Circumnavigate Isla Espiritu Santo this coming March. His doctoral research is being conducted at the University of Stirling in Scotland.

ESS faculty member Virginia Matzek recently collaborated with SCU students Justin Covino (Environmental Science '13), Martin Saunders (Environmental Studies '12), and colleague Jennifer Funk of Chapman University to assess how well knowledge about invasive species is shared between academic researchers and land managers. Their surveys revealed that most practitioners do not read academic papers on invasive species and instead tend to rely on their own experience. Information flow is just as limited in the other direction. Virginia's team recommends that, in addition to developing interdisciplinary research ideas in direct consultation with managers, academic researchers should seek new ways to make their work more accessible, including open-access publishing, presenting results at stakeholder workshops or conferences, and using citizen science.
A paper describing their work has been published in the journal Conservation Letters. The article is open-access and can be downloaded here.

SCU Environmental Studies major Claire Overholt is completing a fellowship through the Leavey School of Business Global Fellows program
For the next five weeks Claire will be interning with a non-profit based in Kolkata, India called the Association for Social and Environmental Development. Claire and her internship partner, Jessica VanderGiessen (a SCU bioengineering student), will be blogging about their experiences at http://asedinterns.wordpress.com/.
Claire and Jessica's goal for their time in India is to promote ASED’s mission of nature conservation through education and to use social media and digital storytelling to help the organization grow. Their blog
will be of interest to anyone who wants to see what environmental studies students can do, what working for a non-profit is like, and what environmental problems and solutions in an emerging economy country look like.

Allison McNamara, a double major in Environmental Studies and Anthropology, has been awarded a Johnson Leadership Experience Stipend to study capuchin monkeys in Costa Rica.
As part of her proposed work, Allison will spend summer 2013 at La Suerte Biological Research Station in northeastern Costa Rica. While there, she will collect behavioral data on both juvenile and adult white-faced capuchin monkeys and record information on activity budget and positional behavior in order to determine differences in tail use and limb use during different developmental stages of the monkeys and how this affects their activity budget.
Senior Kristie Kurtz will be working with Allison to collect data in the field. Dr. Michelle Bezanson of the Dept of Anthropology helped Allison to develop the project and will be working with her on publications after data collection is completed.
Congratulations, Allison, and have fun in Costa Rica!
