“Waste is something that most of us just don’t see,” stressed Pete Pearson, Senior Director, Food Loss and Waste, WWF, at a recent Wilson Center event. Though people are “conditioned” to be blind to food waste, continued Pearson, this not-so-invisible problem wastes a third of food grown around the world. When this wasted food decomposes, it emits methane, accounting for 8 to 10% of global greenhouse gas (GHG) emissions.

World Groundwater Levels Face Accelerated Decline

Nature recently released a report revealing that global groundwater levels have undergone a widespread and accelerated decline over the past 40 years. Researchers concluded that this has likely occurred as a result of the impact of two factors: unsustainable irrigation practices in dry climates and drought driven by climate change.

This past summer was the hottest on record, bringing devastating impacts to many global communities. Iran was one of many nations that faced both debilitating heat and the subsequent water stress.

While Iran’s problems received significant media attention this year, water scarcity in the country is not a new problem. For decades, corruption and poor planning have plagued Iranian water policy, with impacts falling upon its increasingly disadvantaged provinces and, ultimately, on its ethnic minorities. Poor water policy also has contributed to an increasing number of cross-border disputes.

Days before Brazilian President da Silva Feb visited China in late March 2023, China resumed its beef imports from Brazil after a temporary ban due to an earlier discovery of Mad Cow Disease. Brazil quickly bounced back as the top exporter of beef to China, a country hungry for it. With the continuous growth of China’s economy, population, urbanization, and increasing income levels, there has been an increased demand for high-protein foods. Among these, beef has become a highly sought-after delicacy. Since 2012, China has transitioned from a net exporter to a net importer of beef, primarily relying on countries like Brazil.

Extreme heat from climate change threatens food security in the world’s two food-producing superpowers. Climate adaptation for agriculture is a must. The US and China have much to share on climate-smart farming practices to help us both weather the storms and droughts. 2023 brought scorching heat waves that baked crops and livestock in China and the United States. In China, farm animals and fish died from extreme heat in June with some provinces enduring weeks of temperatures above 40°C (104°F). In one farm, a heatwave-triggered power outage resulted in hundreds of pigs suffocating to death after shed fans stopped working.

In a time where climate action is urgent, there are debates how China’s “eco-authoritarianism” can move climate and environmental policies faster than in liberal democracies. Although eco-authoritarianism has some benefits, it is no “green bullet” as divisions between China’s central and local governments and a lack of civic participation can slow or derail some climate and pollution policies.

When cows eat, they burp. And what they exhale generates almost a third of global methane emissions – a greenhouse gas 80 times more potent in warming the climate than CO2. So tracking this short-lived climate gas is crucial.  

Six miles from Bakersfield, California, at the Bear 5 cow feedlot, this work is starting to happen. High-resolution satellites are being used for the first time at the feedlot to track methane emissions from cow burps. Measuring cow belches from space is bringing critical attention to the brewing climate issues from cows. After all, the methane produced by these gassy animals in one year at Bear 5 cow feedlot alone could power more than 15,000 homes in California.  

The idea of climate change as a “threat multiplier” has been gaining steam since it was first proposed roughly 15 years ago. This framing acknowledges that climate can interact with existing political, social, and demographic conditions to heighten communities’ security risks—which in turn suggests that problem-solving in the face of these risks must be interdisciplinary.
