“Changing climate equals changing water” is the phrase that many water and climate experts in the southwest are using today. As the temperature increases, and less rain falls, soils are depleted of moisture in a cycle that turns healthy soil into barren landscapes.

The seeds that we use, the means of careful water use to grow them, and the quality of the fruit and legumes produced are now in a precarious time when climate is less certain. Seeds that are specifically adapted to a region with long genetic history may become more important due to their unique resiliency to heat and drought.

Our commercial, industrialized food system is highly dependent on predictable conditions not only in the agricultural fields but also in the transportation systems that now intersect with a global market system. If too hot, planes may not be able to fly; if sea level rise or large storms destroy ports, cargo ships are not able to pick up or drop off cargo. When food is not shipped in a timely manner, it can rot as it sits in place as with fresh fruit and vegetables.

In Threshold, Ed Flanagan, food bank operations director and climate change denier, has to confront his beliefs as his normal food supply sources are in turmoil.

The dependable food supply we are accustomed to in developed countries is at a threshold with current and predicted climate change realities.  Protecting our food supply personally, nationally, and internationally should be part of the work we all can do to build resilience to changes in our climate.
