How will glibal warming effect the agriculture
Harmful effects of global warming and their consequences on agriculture:
- Warmer waters and more hurricanes:As the temperature of oceans rises, so will the probability of more frequent and stronger hurricanes which can destroy the complete vegetation near the area.
- Increased probability and intensity of droughts and heat waves:Although some areas of Earth will become wetter due to global warming, other areas will suffer serious droughts and heat waves.This can lead to scarcity in some parts of the area which will deplete the growth and quality of the crops.
- Polar ice caps melting:The ice caps melting is a four-pronged danger.It will raise sea levels. There are 5,773,000 cubic miles of water in ice caps, glaciers, and permanent snow. According to the National Snow and Ice Data Center, if all glaciers melted today the seas would rise about 230 feet. Luckily, that’s not going to happen all in one go! But sea levels will rise. This can lead to decrease in availability of pure water for irrigation. (more saline water can deplete the quality or destroy the crops)
- More floods:Flooding represents one of the most dangerous hazards to human settlements and is one of the most potentially momentous impacts of global warming. As the climate changes, a warming of the seas creates ‘thermal expansion’. This is where warm water begins to take up more space than cool water, making the sea’s surface level increase and destroying or making the near land unavailable for agriculture.
- Desertification:An increase in evapo-transpiration and the accompanying decrease in rainfall mean that already semi-arid and sub-humid areas found across the world would face a future barrenness that is almost irreversible. This results in scarcity of water for agriculture in the area.
