Provides an ecological foundation for mgmt. of the diverse ecosystems and fire regimes of N. America, based on scientific principles of fire interactions with vegetation, fuels, and biophysical processes. Detailed discussion of six ecosystems ż ponderosa pine forest (western N. America), chaparral (Calif.), boreal forest (Alaska and Canada), Great Basin sagebrush (inter-mountain West), pine and pine-hardwood forests (Southern Appalachian Mountains), and longleaf pine (Southeastern U.S.) ż illustrates the complexity of fire regimes and that fire mgmt. requires a clear regional focus that reco

Biological diversity is the variety of life on Earth, from the simplest micro-organisms to complex ecosystems such as the rainforests of the Amazon. Biodiversity is important for nutrition and health, and can help to combat micronutrient deficiencies and other forms of malnutrition. Nutrition indicators need to be developed to address the three dimensions of biodiversity - ecosystems, the species they contain and the genetic diversity within species. The indicators will measure the food composition and consumption of cultivars, varieties, breeds and subspecies of commonly consumed foods. This

This report addresses and synthesizes the current state of scientific understanding regarding potential abrupt state changes or regime shifts in ecosystems in response to climate change. It provides an overview of what is known about ecological thresholds and where they are likely to occur. The report also identifies those areas where research is most needed to improve knowledge and understand the uncertainties regarding them. It suggests a suite of potential actions that land and resource managers could use to improve the likelihood of success for the resources they manage, even under conditi

This report synthesizes the findings from the Millennium Ecosystem Assessment (MA) global and sub-global assessments of how ecosystem changes do or could affect human health and well-being. Over the past 50 years humans have changed natural ecosystems more rapidly and extensively than any comparable period in human history. The findings provide the strongest evidence so far of the ways in which pressures on ecosystems have resulted in the loss of vital ecosystem services which purify and replenish water soil and air resources essential to health and also keep many diseases in check. Loss of th
