Effects of Global warming on Agriculture sector

Positive effects

Organic agriculture can remove from the air and sequester 7,000 pounds of carbon dioxide per acre per year. The Rodale Institute study that found that staggering number also found that, when properly executed, organic agriculture does not compromise yield. As a matter of fact, in drought years, it increases yield, since the additional carbon stored in soil helps it to hold more water. In wet years, the additional organic matter in the soil wicks water away from plant roots, limiting erosion and keeping plants in place. Both of those attributes will also benefit organic ag's ability to adapt to the higher highs (and lower lows) of climate change.

 

 

 

 

 

Negative Effects

Industrial agriculture's huge carbon footprint

On the other side of the equation, industrial agriculture -- the practice currently employed by the majority of the developed world -- has a hugely negative impact on global warming. The U.S. food system contributes nearly 20 percent of the nation's carbon dioxide emissions; on a global scale, figures from the Intergovernmental Panel on Climate Change (IPCC) say that agricultural land use contributes 12 percent of global greenhouse gas emissions. Supporting industrial agriculture perpetuates these disturbing practices.

Greenhouse gas emissions from fertilizer and pesticide use

But wait, there's more! If we consider some of the embodied energy required for industrial ag, it gets worse. According to Will Allen, green farmer extraordinaire, including all the "manufacture and use of pesticides and fertilizers, fuel and oil for tractors, equipment, trucking and shipping, electricity for lighting, cooling, and heating, and emissions of carbon dioxide, methane, nitrous oxide and other green house gases" bumps the impact up to between 25 and 30 percent of the U.S.'s collective carbon footprint. That's a big jump.
