How does agriculture food production generate greenhouse gases

Food production results in emissions of carbon dioxide, methane and other planet-warming gases in many ways, including land clearing and deforestation for agriculture and grazing, digestion by cattle and other livestock, production and use of fertilizers and the cultivation of rice in flooded paddies.Nov 6, 2020


How does agriculture generate greenhouse gases?

Airborne greenhouse gases are responsible for the effects of climate change. Carbon dioxide is emitted by farm equipment moving across the farm’s fields during tilling, planting, the application of pesticides and fertilizers and harvest. The more passes across the farm field, the more carbon that is emitted.


How much does food production contribute to greenhouse gases?

Soil tillage, crop and livestock transportation, manure management and all the other aspects of global food production generate greenhouse gas emissions to the tune of more than 17 billion metric tons per year, according to a new study published on Monday in Nature Food.


Why does food production cause global warming?

Food waste produces 3.3 billion tons of carbon dioxide, a greenhouse gas that contributes to climate change. If food waste were a country it would be the third largest emitter of greenhouse gases after the US and China. By the year 2050 the world’s population will increase 33% to 10 billion.


How does food production contribute to global warming?

Food system activities, including producing food, transporting it, and storing wasted food in landfills, produce greenhouse gas (GHG) emissions that contribute to climate change.


A Background on Greenhouse Gases

Image
When we think of environmental concerns, the sustainable use of natural resources such as water, energy and soil may come to mind—and so too does the emission of greenhouse gases. Greenhouse gases are defined as the gaseous compounds in the Earth’s atmosphere (such as carbon dioxide) that absorb infrared radiation, tr…

Greenhouse Gases and Farming

  • The top three greenhouse gas–emitting groups globally are China, the European Union and the United States—combined they contribute 41.5% of total global emissions. Efforts to decrease emissions in these sectors of the world are paramount in decreasing overall gas emissions and the impacts of the greenhouse effect. Here in the United States, there are six major contributors …

Efforts to Decrease Emissions

  • While there is much work to be done to reduce emissions from the above-mentioned sectors, there are various activities in progress to reduce emissions from land and crops, livestock, and manure management. For instance, farmers are fertilizing crops with enhanced nitrogen monitoring—too much nitrogen can contribute to higher nitrous oxide emissions…
