New Understanding Of How Humans And The Environment Interact

September 21, 2011

National Science Foundation Grants Awarded for Research on Coupled Natural and Human Systems

Water quality and environmental health in Botswana; wetlands in a working landscape; the collapse of the ancient Maya and what that has to tell us about society and environmental change today.

These and other projects that address how humans and the environment interact are the focus of $21 million in National Science Foundation (NSF) grants to scientists, engineers and educators across the country to study coupled natural and human systems.

Research conducted through NSF’s Dynamics of Coupled Natural and Human Systems (CNH) program, in its fifth year as a multi-directorate program, will provide a better understanding of natural processes and cycles, and of human behavior and decisions–as well as how and where they intersect.

The CNH program is largely supported by NSF’s Directorates for Biological Sciences (BIO), Geosciences (GEO) and Social, Behavioral & Economic Sciences (SBE).

“This year’s CNH awards highlight the need for scientists from different fields to work together and benefit from each other’s perspectives to gain an understanding of the complex ways people interact with Earth’s natural systems,” says Tom Baerwald, CNH program director in SBE.

“Findings from these projects,” Baerwald says, “will help individuals and groups address environmental problems more effectively.”

What are the social processes at work in wetlands in agricultural areas and rangelands of the Sierra Foothills of California?  What links human and other animal populations in the Chobe River region of Botswana, and how is the microbe E. coli transmitted among the river, wildlife, domestic animals and humans? How and where has land use intensified over time around parks in eastern Africa?

These are some of the questions asked by scientists funded through the CNH program.

“This year has another great set of projects that showcase interdisciplinary research,” says Sarah Ruth, CNH program director in GEO.

“By bringing together researchers from a wide variety of academic fields,” Ruth says, “the projects will provide valuable new insights into the ways in which we, our environment, and the natural resources we rely on for our survival act as one interconnected system.”

“The diversity of topics in these awards shows the intellectual richness of the CNH program, and its relevance to NSF’s investments in sustainability research and education,” says Alan Tessier, CNH program director in BIO.

“The projects address key societal challenges in the management of ‘ecosystem services’ and in adaptation to climate change.”

Interactive Dynamics of Wildlife Populations, Human Health and Household Wealth in Rural Africa
Justin Brashares, University of California-Berkeley
Scientists will integrate ecology, economics, sociology and public health to understand and predict how human health and household wealth affect human reliance on biodiversity. The research will take place at nine rural sites in Ghana, Kenya and Madagascar.

The Collapse of the Ancient Maya: Interdisciplinary Research on Society and the Environment
Nicholas Brokaw, University of Puerto Rico-Rio Piedras
Researchers will examine the collapse of an ancient civilization, and the consequences of deforestation in the tropics by exploring interactions between the Maya and their environment. These interactions, it’s believed, contributed to the collapse of the Maya civilization. The scientists will also assess the impact of ancient Maya land use, from the period 1,200 years ago to the present.

Land-Use Intensification and Protected-Area Vulnerability in Africa’s Albertine Rift
Joel Hartter, University of New Hampshire
Scientists will study how and where land use has intensified over time around parks in the Albertine Rift of eastern Africa by quantifying the rate and extent of forest conversion around seven Ugandan parks. Through this information, the researchers will identify patterns of climate, land use and population change over the last decade.

Political Fragmentation in Local Governance and Water Resource Management
