Toll on the Commons: What Have We Taken and What Will be the Future Costs

4/23/2012; 59 minutes

For millennia, humans have harnessed common resources — atmosphere, water, land, and biotic resources — to enrich and nurture their well-being with little regard for sustainability and stewardship of these precious resources . Dennis Ojima, Colorado State University, argues that as a result, we are now faced with serious degradation of ecosystem services. Given our current knowledge of how ecosystems operate and how human activities have altered ecosystem services, we need to develop strategies that restore these ecosystem services. These strategies can be developed to reduce catastrophic collapse of social-ecological systems in ways that enhance system resilience and lead to sustainability of ecosystem services. A select set of strategies will be explored to deal with ecosystem resilience relative to security of energy, food, and water resources. (#23501)
