Agriculture accounts for 20% of greenhouse gas emissions, globally. The main GHG’s produced by agriculture are methane and nitrous oxide, although carbon dioxide emissions are also notable. Agriculture demands a significant amount of energy for things like crop growth and harvesting, and what’s more, the energy is not efficiently used. For example, reducing the dependence on nitrogen for fertilizing would be a positive step towards reducing the amount of GHG’s emitted from agricultural activities.
Agriculture has a significant effect on climate change through the production of greenhouse gasses like carbon dioxide, methane and nitrous oxide. Agriculture also significantly alters the Earth’s land cover, which than changes it’s ability to absorb or reflect heat and light. Land use can also lead to deforestation and desertification. Agriculture also increases our use of fossil fuels in many ways, not least of which includes transportation of product all over the world.
Climate change also impacts agriculture – due to fluctuating and changing temperatures, glacial run-off, percipitation and increased storm activity.
25% of carbon dioxide emissions are produced by agricultural sources, specifically deforestation. Agriculture processes comprise 54% of methane emissions and roughly 80% of nitrous oxide emissions. Therefore, agriculture is contributing quite a lot to global warming. More information can be found at the website provided.
