New director comes from Nashville; decarbonization of city a central duty

Paige Travis is a public information specialist for the city of Knoxville.

KNOXVILLE — Mayor Indya Kincannon appointed Metro Nashville Decarbonization Manager Vasu Primlani as Knoxville’s next director of sustainability.

Primlani has more than three decades of experience in sustainability and has received awards for environmental innovation, including the EPA’s Environmental Achievement Award.

“Vasu has an incredible track record in this field,” Kincannon said. “Her experience and creative thinking will help Knoxville meet our goal of an 80 percent reduction in greenhouse gases by 2050.  

“I am also impressed with her focus on equity. We must adapt to climate change in a way that is just, equitable, and helps everyday people and small business owners save money too.”

By providing both mitigation and adaption, dam removal can lower greenhouse gas emissions and restore carbon sinks.

As the climate crisis escalates, a huge amount of attention and money is being focused on climate solutions.

These can be divided into two categories: solutions that pursue “mitigation,” which lowers greenhouse gas emissions, and those that pursue methods to adapt to climate impacts to increase human and ecological resiliency.

Dams, of course, create enormous environmental harms, many of which have already been described in scientific literature. Equally well documented is the fact that removing dams can restore seriously damaged ecosystems. But missing from almost every climate-solution story and study is how dam removal can be key for both mitigation and adaptation.

Here are 10 reasons how dam removal fights climate change.

Research from Kimberly Sheldon at the University of Tennessee suggests insect behavior is adjusting for climate change

If the TV series “Dirty Jobs” covered animals as well as humans, it would probably start with dung beetles. These hardworking critters are among the insect world’s most important recyclers. They eat and bury manure from many other species, recycling nutrients and improving soil as they go.

Dung beetles are found on every continent except Antarctica, in forests, grasslands, prairies and deserts. And now, like many other species, they are coping with the effects of climate change.

I am an ecologist who has spent nearly 20 years studying dung beetles. My research spans tropical and temperate ecosystems, and focuses on how these beneficial animals respond to temperature changes.

The average American family of four annually spends more than $2,000 on food they never eat!

Nearly one in nine people suffer from hunger worldwide.

Agriculture contributes to global greenhouse gas emissions, deforestation and soil degradation.

Climate change increases crop losses.

One third of all food produced in the world is lost or wasted.

It’s not just the food that’s wasted.

Consider the energy wasted to grow, process and transport it.

That all contributes to climate change, food shortages and to the rising costs of food, energy and health care.

Food waste stresses our environment, humanity and the economy.

Shut up and get on the bus

KNOXVILLE — Everyone needs to be everywhere at once: School, work, the grocery story, the mall and back home.

Locked into a society run by time, we tend to prefer methods of transportation that make for the quickest journey from place to place.

The modern car, usually powered by gasoline, provides individuals with quick transportation, which saves time. Private transportation embodies convenience.
