How far, and in what ways, can Earth's systems be stressed before they undergo transitions to new states--with unforeseen consequences?
For most of its history, Earth experienced vast alterations in response to natural, planetary variations, says Saran Twombly, program director for the National Science Foundation's (NSF) Long-Term Ecological Research (LTER) Network. Humans, however, are now emerging as the dominant agent of change.
The world is at a crossroads, say scientists. With growing problems such as resource depletion, energy sustainability, environmental degradation and climate change, how can people protect the health of the planet while achieving widespread economic prosperity?
Scientists say the answer is a sustainable world, one in which human needs are met without harm to the environment and without sacrificing the ability of future generations to meet their own needs.
To respond to this challenge, more information is needed about how the natural world, society and human alterations to the environment fit together.
On Thursday, March 1, 2012, NSF will host a symposium titled "How Long-Term Ecological Research Informs Sustainability Science and Action."
The meeting is the 11th such annual NSF symposium to address topics in long-term ecological research.
Scientists across NSF's LTER Network look at new ways of asking and answering questions about a sustainable future: where have we been, where are we going, and how do we best get there?
We must move beyond identifying issues and toward providing sound bases for the development of innovative solutions, as well as toward effective adaptation and mitigation strategies, these scientists believe.
Presentations at the symposium will address the sustainability of agriculture in view of biofuels markets; resilience in marine environments; graduate education on sustainability science; local knowledge of sustainability and resilience in indigenous villages; urban water sustainability; how to build knowledge and action systems in urban areas; and using the landscape to mitigate vulnerability and enhance resilience.
Scientists from several NSF LTER sites will discuss how to address sustainability challenges in the shadow of the huge global footprint produced by humans.
NSF's LTER Network spans the Arctic to the Antarctic to the tropics. The 26 sites represent Earth's major ecosystems, and include grasslands, forests, tundra, urban areas, agricultural systems, freshwater lakes, estuaries and salt marshes, coral reefs, coastal zones and the open sea.
A special feature of this year's symposium is an exhibit titled "Long-Term Ecological Reflections."
Several LTER sites support collaborations between scientists and artists. Projects explore the past, present and future scenarios of land use and environmental change. "They inspire broad audiences to a deeper understanding of the natural world," says Twombly.
The exhibit features a collection of ecological reflections from three LTER sites: Bonanza Creek in Alaska; Harvard Forest in Massachusetts; and North Temperate Lakes in Wisconsin. It will be displayed in NSF's exhibit space on the third floor.
