How could climate change affect agricultural and food production

image

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.


What are the effects of climate change on agricultural production?

Changes in ozone, greenhouse gases and climate change affect agricultural producers greatly because agriculture and fisheries depend on specific climate conditions. Temperature changes can cause habitat ranges and crop planting dates to shift and droughts and floods due to climate change may hinder farming practices.


How will climate change affect food production?

In short, climate change is putting food production at risk. Yield growth for wheat, maize, and other crops has been declining in many countries due to extreme heat, severe weather, and droughts. By some estimates, in the absence of effective adaptation, global yields could decline by up to 30 percent by 2050.


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.


How will climate change affect agriculture quizlet?

Amount of pests will increase, since warmer temperatures produce more generations of pests per year. Agriculture responds to weather; increasing floods and droughts will reduce agricultural production (aka food availability).


Overview


Impacts on Crops

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

U.S. farms supply nearly 25% of all grains (such as wheat, corn, and rice) on the globa…

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…
