Climate change can disrupt food availability, reduce access to food, and affect food quality. For example, projected increases in temperatures, changes in precipitation patterns, changes in extreme weather events, and reductions in water availability may all result in reduced agricultural productivity.


How does climate change have an impact on food security?

Climate change has been found to have an impact on food safety, particularly on incidence and prevalence of food-borne diseases. Increased climate variability, increased frequency and intensity of extreme events as well as slow ongoing changes will affect the stability of food supply, access and utilization.


How does climate change affect agriculture?

Agriculture emits an estimated 10.5 percent of total U.S. greenhouse gases; however, agriculture also provides opportunities to reduce greenhouse gas emissions and remove carbon dioxide from the atmosphere.


How does climate change affect agriculture essay?

Climate change is affecting agriculture by interfering with the efficiency of crop production. Agriculture is facing droughts, flooding, sea level elevations, natural disasters, and health hazards for employees. All of these exponents lead to crop failure that creates famines and food prices to rise.


Which effect of climate change will prompt changes in agricultural practices?

Air Pollution 7 Which effect of climate change will prompt changes in agricultural practices?  Warming temperatures bring new pests into an area.


Overview


Impacts on Crops

  • Despite technological improvements that increase corn yields, extreme weather events have caused significant yield reductions in some years.

Impacts on Fisheries

  • American fishermen catch or harvest five million metric tons of fish and shellfish each year. U.S. fisheries contribute more than $1.55 billion to the economy annually (as of 2012).Many fisheries already face multiple stresses, including overfishing and water pollution. Climate change may worsen these stresses. In particular, temperature changes could lead to significant impacts. Thi…
