How has agriculture increased?

Agricultural methods have intensified continuously ever since the Industrial Revolution, and even more so since the “green revolution” in the middle decades of the 20 th century. At each stage, innovations in farming techniques brought about huge increases in crop yields by area of arable land. This tremendous rise in food production has sustained a global population that has quadrupled in size over the span of one century. As the human population continues to grow, so too has the amount of space dedicated to feeding it. According to World Bank figures, in 2016, more than 700 million hectares (1.7 billion acres) were devoted to growing corn, wheat, rice, and other staple cereal grains—nearly half of all cultivated land on the planet.

Worldwide, agriculture accounts for 70 percent of human freshwater consumption. A great deal of this water is redirected onto cropland through irrigation schemes of varying kinds. Experts predict that to keep a growing population fed, water extraction may increase an additional 15 percent or more by 2050. Irrigation supports the large harvest yields that such a large population demands. Many of the world’s most productive agricultural regions, from California’s Central Valley to Southern Europe’s arid Mediterranean basin, have become economically dependent on heavy irrigation.

We’ve said it before and we’ll say it again: 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.

Does drought increase 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.

Does cutting down a forest make it cooler?

The difference here is that we’re talking surface warming, rather than changing atmospheric conditions, and, while chopping down a forest might make it feel cooler, forests have a much greater potential to sequester carbon dioxide than does monocultural, industrial agriculture (and there goes the baby with the bathwater). The bottom line: The effect of land use conversion on rising surface temps is an underestimated component of global warming, and just because it feels cooler today than it did yesterday does not mean big-time climate change is right around the corner.
