Presentation Transcript

  1. Climate Change, Soils, and Human Health Dr. Eric C. Brevik Dickinson State University Dickinson, ND, USA

  2. Soils are important for human health • Production of food • Exposures to harmful chemicals • Disease-causing organisms • Filter for water • Medications • About 40% of prescription drugs have their origin in soil

  3. Soils are linked to the atmosphere • Changes in atmospheric carbon affects soils • Changes in temperature/precipitation affect soils

  4. Climate change, soils, and human health • Indirect effects • Increased deaths related to temperature extremes • Increased tropospheric ozone concentrations leading to respiratory problems • Increased range for vectors

  5. Climate change, soils, and human health • Direct effects • Changes in soil properties due to climate change could influence nutrient cycling and the carbon cycle, compromising food security • Atmospheric dust generated from soil is expected to increase with climate change
