Boston and Baltimore. Miami and Minneapolis. Phoenix and Los Angeles. Fanned across the U.S. and in locations from coast to prairie to desert, what do these cities have in common? Perhaps how their human residents tend that icon of America, the urban lawn.

What's right outside our doors -- our lawns -- may be one of the best indicators of where cities and towns need to address sustainability, according to Peter Groffman of the City University of New York.

Groffman is one of 14 recipients of grants made in 2016 by the National Science Foundation (NSF)'s Dynamics of Coupled Natural and Human Systems (CNH) program, which supports research that examines the complex interactions between human and natural systems. Total funding for 2016 CNH grants is $16.7 million.

Lawn fertilizer contains nutrients such as phosphorus and nitrogen that wash into waterways, causing blooms of algae that can rob fish and other aquatic species of oxygen and degrade water quality. Groffman's CNH project will investigate the natural processes regulating the flow of nitrogen from lawns, and look at the sociological factors that influence how homeowners decide to manage their lawns.

CNH is co-funded by NSF's directorates for Biological Sciences (BIO), Geosciences (GEO), and Social, Behavioral and Economic Sciences (SBE). The program has been issuing awards since 2001. 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.

"As has been true for the 15 years since CNH was founded, this year's awards explore a diverse range of ways in which natural and human systems interact with each other," said Tom Baerwald, CNH program director for SBE.

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

The 2016 CNH research subjects include: adaptations to climate change in California fisheries and fishing communities; how land transactions and investments affect agricultural production, ecosystem services and food and energy security; how socioecological systems are transformed by hydroelectric dams in the Amazon; the restoration of riparian forests in the southwestern U.S.; and the effects of glaciers melting on the livelihoods of townspeople in Peru's high-elevation Cordillera Blanca.

"The CNH program is unique in that it involves interdisciplinary research teams in solving the complex challenges facing our country and our planet," said Betsy Von Holle, CNH program director for BIO.

CNH considers humans and the environment as one interconnected system.

"The program provides a knowledge base for sound planning that can benefit both people and the environment for years to come," said Richard Yuretich, CNH program director for GEO.

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) 2016, 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. NSF also awards about $626 million in professional and service contracts yearly.
