Connecting the Dots on Ag and Climate Change

This weekend, hundreds of thousands of citizens will march in Washington, D.C., and around the world, raising their voices to demand action on climate change, one of the most critical issues of our day.

Energy and fossil fuel will be at the center of the dialogue, of course, but it’s also critical to address the reality that our industrial agriculture system—drenched in fossil fuels and sucking up energy, water, and other critical resources—is a leading climate change culprit. In fact, agriculture systems contribute at least 30 percent of global greenhouse gas emissions (GHGs). Even more stunning, use of synthetic nitrogen fertilizers on agriculture crops accounts for approximately 60 percent of global nitrous oxide emissions, a compound around 300 times more potent than carbon dioxide (CO2).

It doesn’t have to be this way: A global shift to sustainable farming will not only help create a stable climate, it will also improve food and water security and safety, sustainable rural livelihoods, and environmental health. But industrial agriculture requires the production and use of toxic chemicals; converts forests, marshes, and other lands to agricultural uses; and encourages excessive tillage, unhealthy livestock-rearing conditions, and long-distance food transport—all climate-changing practices responsible for inefficiencies, inequities, and conflict the world over.

Massive use of agricultural chemicals has degraded the health of our soils so significantly that crop yields have plateaued or collapsed in some regions. Scientists estimate that 50 to 70 percent of carbon has been lost in industrially farmed soils. That carbon escapes into the atmosphere, causing increased levels of CO2. It also dissolves into our oceans, causing raised acidity levels that threaten marine life and critical food systems. Additionally, after decades of intensive over-use, pest and plant diseases are becoming resistant to fossil fuel-based chemicals.

On the inequity front, despite the supposed merits of our global industrial agriculture system, at least 2 billion people around the globe are chronically undernourished. And climate change further exacerbates food insecurity. Global agencies agree that crop productivity will markedly decline over the next few decades in Central America, South and Southeast Asia, and sub-Saharan Africa—regions already hard-hit by unstable food supply.

Catastrophic weather related to global warming not only spikes food insecurity, but leads to national and international conflicts over resources, migration and refugees. Take for example the current crisis in Syria. Very few would utter the words “climate change” in the same sentence as “the war in Syria,” but the truth is global warming in the region played a significant role in the present tragedy.
