Please vote for the environment in the #Colorado primary election, June 26, 2018

Brad Udall likes to tell folks that, “Climate change is water change,” and he is right.

Please consider voting for the environment. You owe it to those that have a good chance of being alive in 2050. With the CO2 in the environment already the atmosphere will continue to warm for generations. Science has known about the greenhouse gas effect over a 100 years.

Here’s a look at water sustainability from Rebecca Lorenzen writing for NewSecurityBeat:

Food and Floods: Challenges

“Agriculture currently uses about 70 percent of the world’s freshwater resources, with only about 10 percent going to cities and residents, and 20 percent going to industry,” said Kate Tully, Assistant Professor of Agroecology at the University of Maryland. Water is “embedded in the foods that we eat,” she said; the most “water hungry” foods—like beef and pork—represent much more water use than poultry and legumes.

Through agricultural products, virtual water moves around the world. “The globalization of trade has decoupled the environmental effects that are a result of our agricultural production from the places that are consuming those products,” said Tully. “We now are relying very heavily on a few water-rich regions to provide most of our food.”

But environmental changes, including climate change, may threaten this reliance. For example, at the current rate of sea-level rise, a good portion of habitable and agricultural land space in Bangladesh will be underwater. In Africa and Asia, eight major crops may be lost by 2050, warned Tully.

Droughts and floods in the United States also threaten trade. The U.S. Army Corps of Engineers, which manages navigable rivers, channels, and dams, can recover from floods relatively quickly, said Kathleen White, the lead of the Corps’ Climate Preparedness and Resilience Community of Practice. But droughts can present significant challenges: If “you can’t get any barges down the river, then there’s a real problem.” Improving the United States’ hydroclimatic forecasts will help improve dam management, she said.
