Projected Impacts By Sector
Projected Change Agriculture, Water Resources Human Industry/Settlement/Society
Forestry Health/Mortality
Warmer/fewer cold days Increased yields in Effects on water Reduced human Reduced energy demand for
and nights; warmer/more colder resources relying on mortality from heating; increased demand for
hot days and nights over environments; snow melt decreased cold cooling; declining air quality in
most land areas decreased yields in exposure cities; reduced effects of snow, ice
warmer etc.
environments
Increase in the frequency of Reduced yields in Increased water Increased risk of heat- Reduction in quality of life for
warm spells/heat waves warmer regions due demand; water quality related mortality people in warm areas without air
over most land areas to heat stress at key problems, e.g., algal conditioning; impacts on elderly
devel. stages; fire blooms and very young; reduced
danger increase thermoelectric power production
efficiency
Increase in the frequency of Damage to crops; Adverse effects on Deaths, injuries, Disruption of settlements,
heavy precipitation events soil erosion, quality of surface and infectious diseases, commerce, transport and societies
over most land areas inability to groundwater; allergies and dermatitis due to flooding; pressures on urban
cultivate land, contamination of from floods and and rural infrastructures
water logging of water supply landslides
soils
Increase in the area affected Land degradation, More widespread Increased risk of food Water shortages for settlements,
by drought lower yields/crop water stress and water shortage and industry and societies; reduced
damage and failure; wild fires; increased hydropower generation potentials;
livestock deaths; risk of water- and food- potentials for population migration
land degradation borne diseases
Increase in the number of Damage to crops; Power outages cause Increased risk of Disruption by flood and high
intense tropical cyclones windthrow of trees disruption of public deaths, injuries, water- winds; withdrawal of risk coverage
water supply and food-borne in vulnerable areas by private
diseases insurers
Increase in the incidence of Salinization of Decreased freshwater Increase in deaths by Costs of coastal protection versus
extreme high sea level irrigation and well availability due to drowning in floods; costs of land-use relocation; also
water saltwater intrusion increase in stress- see tropical cyclones above
