Stresses such as land and water use changes, resource exploitation, invasive species, pollution and nutrient enrichment, and climate change, produce adverse effects on the Nation's environmental resources. Science can help determine whether and how these stresses have impaired ecosystem structure and function and identify approaches to prevent further damage, preserve and improve productivity and resiliency, and enhance recovery. To improve the science base and help guide decisionmakers in these efforts, the budget includes substantial increases in a number of environmental research programs.

Integrated Science for Ecological Challenges (ISEC). The budget provides $96 million for the ISEC initiative, to be shared among USDA, USGS, NOAA, NSF, and EPA. ISEC will:

Global Change Research: The budget provides $1.786 billion for the GCRP, a $105 million increase over FY 1999. $828 million of this amount is for scientific research focused on increasing our knowledge of: The remainder of the FY 2000 request ($958 million) is for NASA's development of climate-monitoring satellites, including funding for Vegetation Canopy Lidar (VCL), which will give scientists the first 3-dimensional view of the earth's forests to help determine their contribution to sequestering atmospheric CO2.

Improving Our Understanding of Carbon Sinks and Sources: The budget includes $189 million for a focused program of research to resolve critical issues on the carbon cycle. The research targets significant uncertainties on how much carbon is taken up by terrestrial sinks and how long such sinks will last, and ultimately will address 5 objectives:
