How do predators contribute to reducing crop losses in agricultural ecosystems? By consuming crop-eating insects and rodents, according to Catherine Lindell of Michigan State University.

Lindell is one of 16 recipients of grants made in 2015 by the National Science Foundation's (NSF) Dynamics of Coupled Natural and Human Systems (CNH) program.

She and colleagues are investigating whether predatory bird populations, in this case American kestrels, increase when researchers provide nest boxes in fruit-growing regions--and whether these predators reduce crop damage.

The scientists are also studying factors that may influence fruit growers' decisions about the use of predator nest boxes, including economic and consumer preference considerations. The project addresses how humans and the environment interact--and where predators such as American kestrels fit into the picture.

Another new CNH project, by Andrew Ashton of the Woods Hole Oceanographic Institution, looks at how coastlines are influenced by physical processes. Project researchers are developing a set of integrated models to better understand shoreline evolution in different geologic settings, development scenarios, legal and regulatory regimes, and with different climate variables and strategies for coastal protection and response.

Studying complex interactions

Total funding for the 2015 CNH grants is $20.4 million; the program has been issuing awards since 2001.

CNH is co-funded by NSF's Directorates for Biological Sciences (BIO), Geosciences (GEO), and Social, Behavioral & Economic Sciences (SBE).

"Past CNH-supported research has examined the complex and often unanticipated ways human actions interact with biophysical processes," says Tom Baerwald, CNH program director for SBE. "The 2015 awards will lead to new insights into, and perspectives on, linked human and natural systems that are important at local, regional, national and global scales."

This year's grantees will look at ways in which people deal with environmental processes in a range of settings, including cities, mountains, grasslands and forests.

Findings from the projects, scientists believe, will enhance society's understanding of environmental quality and the well-being of people.

The 2015 research subjects include community management of tropical forests, links between ecosystem services and governance of water resources in urbanized landscapes, humans and wildlife as coupled systems, social and ecological consequences of conservation easements, and globally driven subsistence changes in rural Alaska.

"As human populations expand and the environment changes, that creates complex environmental issues that are best investigated by multidisciplinary teams," says Betsy Von Holle, CNH program director for BIO. "CNH provides support for natural and social scientists to work together to examine these complex human-environment interactions. The results can then be applied to other regions experiencing similar issues."

The CNH program considers humans and the environment as one interconnected system.

"CNH brings together expertise in physical, biological, and social science to solve real and complex problems affecting people," says Richard Yuretich, CNH program director for GEO. "These range from sustaining fisheries for local communities to examining the practical aspects of shoreline erosion to determining how human behavior and environmental factors interplay in the spread and prevention of water-borne disease. Every CNH project considers humans as an integral part of the functioning of this planet, which indeed we are."

The National Science Foundation (NSF) is an independent federal agency that supports fundamental research and education across all fields of science and engineering. In fiscal year (FY) 2017, its budget is $7.5 billion. NSF funds reach all 50 states through grants to nearly 2,000 colleges, universities and other institutions. Each year, NSF receives more than 48,000 competitive proposals for funding and makes about 12,000 new funding awards.
