Shading Tucson: Trees to the Rescue

Tuesday, February 13, 6:00-7:30 pm

The weather keeps getting hotter and drier in southern Arizona.  In 2021, the EPA reported that Pima is the third fastest warming county in the US.  In 2023, July was Tucson’s hottest month on record.

We need more shade!  This was the chorus from Tucson residents as the City worked on its climate action plan, Tucson Resilient Together.  The Million Trees project is a big part of the community’s effort to cool the urban heat island.  A side-benefit:  according to a report in Science (Bastin et al, 2019), “Photosynthetic carbon capture by trees is likely to be among our most effective strategies to limit the rise of CO2 concentrations.”  Other benefits of city trees include:

  • Cleaning the air
  • Beautifying neighborhoods, business districts, parks
  • Calming traffic
  • Reducing risk of violence
  • Providing habitat for birds

Join us for a panel conversation on what we can do to expand the urban forest, especially in parts of Tucson that are currently sparsely shaded. 

Panelists:
Adam Farrell-Wortman, director of horticulture at Tucson Botanical Gardens, manages the care of a diverse palette of herbs, forbs, cactus, shrubs, and trees.  As a garden steward and educator, Adam specializes in regenerative practices such as composting and mulching.  Currently, he is overseeing a study of natural soil regeneration for the health and vigor of trees in the Gardens.
Ann Audrey, lead consultant on Tucson’s Urban Forest Master Plan and author of the guidebook, Native Trees for Tucson:  Ten Best Practices for Using Native Trees to Improve Urban Climate Change Resilience.  Other projects include a response guide to insect and disease threats in urban forests of Arizona and New Mexico, and editing the Rainwater Harvesting Manual, used throughout the US to train rainwater harvesting professionals.
Vikram Krishnamurthy leads the Tree Equity Alliance, a cross-sector initiative launched by American Forests to unite diverse national partners in supporting the national Tree Equity movement.  Prior to joining American Forests, Vikram served as Executive Director of the Delaware Center for Horticulture, an urban greening nonprofit based in Wilmington. In addition to reinventing DCH’s Branches to Chances® workforce and re-entry program, he helped to launch the Delaware River Climate Corps program.  He brings experience in urban forestry, land conservation and local food systems, all of which contribute to his commitment to equity and environmental justice.

An Easy Step for Cleaner Air

Tuesday, December 12, 6:00-7:30 pm

Did you see the recent report on the impacts of landscape equipment, “Lawn Care Goes Electric”?  One finding:  “In the United States, lawn and garden equipment powered by gasoline and other fossil fuels released more than 30 million tons of carbon dioxide to the atmosphere in 2020 – more than all the greenhouse gas emissions from the city of Los Angeles.”
 
There are other pollutants, too:  Using a commercial leaf blower for an hour, the report notes, emits “as much smog-forming pollution as driving 1,100 miles in a car.”
 
Come learn more about the costs  — to our climate and our health — of gas-powered landscape equipment and the steps being taken in Tucson and beyond to make the transition to manual and electric power.  A representative of Pima’s Department of Environmental Quality will provide context and describe a voluntary program that helps landscapers or households make the shift.

Exploring Our Local Native Food System

October 10, 2023 • 6:00pm

Tucson is increasingly becoming known as a major “food city.” What many may not realize is the long history of local agriculture and distinctive food traditions in our region. Join us on October 10 for our next monthly meeting for an exploration of that history and some of the ways in which regional traditions and uniquely desert-adapted foods are still important and will play a significant role in shaping a sustainable food future.
 
We are pleased to present two speakers who will share their deep familiarity with the deep roots and current practices of local desert agriculture and the distinctive food culture it produces. Sterling Johnson is Co-Executive Director and DeAnndra Porter is Outreach Coordinator of Ajo Center for Sustainable Agriculture (Ajo CSA), a Native American-governed non-profit organization in Ajo, Arizona. Ajo CSA provides agricultural education, reduces barriers to healthy and culturally appropriate foods, preserves and revitalizes agricultural traditions, fosters local, food-based economic development, and establishes valuable partnerships. Their mission is to support the development of a sustainable and just local food system in Ajo, Arizona and the Tohono O’odham Nation.
 
Johnson and Porter will share insights from their organization’s programming, which includes educating youths and adults on traditional foods, the Adopt-A-Sonoran-Desert-Crop Program, and Climate Smart Agriculture or traditional agricultural practices. With the impacts of climate change, farmers, growers, and ranchers continue to adapt. Traditional Tohono O’odham agriculture is climate smart agriculture. It includes practices such as ak-chin farming, an ancient but efficient system based on rainwater harvesting.

Sterling Johnson was born and raised on the Tohono O’odham Nation and is a proud tribal member who represented his tribe by ranching and competing in rodeos. Today Sterling is a traditional dry-land farmer and an urban farmer, as well as a farmer mentor for Ajo Center for Sustainable Agriculture. Sterling mentors new apprentices and goes to schools both on and off the reservation to educate students. As a part of Ajo CSA, Sterling grows seeds out for Adopt a Sonoran Desert Crop Program, which gives out native grown seeds and non-native grown seeds that have been surviving out in the Desert for hundreds or even thousands of years.

DeAndra Porter, also from the Tohono O’odham Nation, is a recent graduate from the University of Arizona in Nutrition and Food Systems. She is currently working with Ajo Center for Sustainable Agriculture as an Outreach Coordinator and with Native Seed Search as a seed saving apprentice. Her interests include gardening, being outdoors, and learning more about sustainable living and growing, nutrition, and community development.

As we see all too often in the news, the world’s biodiversity faces many challenges and threats, even including risks of multiple extinctions across the globe. In the US, concerns about biodiversity seem to be highlighted by this year’s 50th anniversary of the Endangered Species Act, and globally we begin to see an awakening to the need for action, for example, the recent launch of the Global Biodiversity Framework Fund.
 
Closer to home, we’re fortunate to live in one of the world’s most biodiverse regions. Yet here too, the flora and fauna in the Sky Islands and the Sonoran Desert face many threats challenging their survival.
 
Join us for our next monthly meeting, Tuesday, September 12, at 6:00 pm, for an overview of key issues impacting biodiversity in our region. Our speaker is Laiken Jordahl,Southwest Conservation Advocate with the Center for Biological Diversity, based here in Tucson. Laiken will give a brief overview of regional biodiversity and then share work being done to protect biodiversity in the borderlands in the face of myriad threats, including border walls and militarization, industrial-scale mining, and rampant and illegal cattle grazing of our vanishing wetlands – all of which are contributing significantly to biodiversity loss in the region. Following his presentation there will be ample time for Q & A.
 
Laiken works to protect wildlife, ecosystems, and public lands throughout the desert Southwest and U.S-Mexico borderlands. Before joining the Center, he worked with the National Park Service studying threats to wilderness character at five different national parks and monuments and with the Bureau of Land Management on recreation planning for the San Juan River. He has also worked as a natural resource legislative fellow in the U.S. House of Representatives. For four years Laiken worked as the Center’s Borderlands campaigner, fighting wall construction in Arizona and across the southwest, before recently transitioning into his current, more general role as a Southwest Conservation Advocate.

“Chemical Recycling” of Plastic: A Burning Issue

Tuesday, June 13 at 6:00pm

As public concern grows about the plastic waste crisis, the petrochemical and plastic industries are promoting a suite of environmentally troublesome technologies that they misleadingly call “chemical recycling” (also known as “advanced recycling”) as a solution to the crisis.  Chemical recycling isn’t really recycling at all.  This supposed cutting-edge technology most often involves turning plastic into fuel. Here in Tucson, the Environmental and General Services Department has solicited seven project ideas for turning plastic or mixed waste into gaseous and/or liquid fuels that will be burned, using pyrolysis and gasification systems. The Department is also studying two proposals that would turn discarded plastics into chemical feedstocks to make new plastic.

Chemical recycling represents a dangerous false solution to the plastic epidemic. These high-heat systems most often use plastic materials to generate a limited amount of fuel in a one-time process, destroying them rather than giving them another material use. These processes, which are energy-intensive, generate greenhouse gases and toxic fumes. Some also produce hazardous waste. Chemical recycling will not solve the plastic waste crisis. What is needed instead are policies that reduce plastic production and waste, particularly single-use packaging.

Join us at our June 13 monthly meeting to learn about the health and environmental hazards of chemical recycling. Our guest speaker will be Dr. Veena Singla, Senior Scientist, People & Communities Program at the Natural Resources Defense Council. Time for Q&A will follow her presentation.


Dr. Singla, who is also an adjunct assistant professor at Columbia University, oversees a program that addresses health disparities linked to harmful environmental exposures. Her research investigates how toxic chemicals and pollution related to systems of materials use, production, and disposal threaten the health of impacted communities.

Dr. Singla currently serves on the U.S. Environmental Protection Agency’s Children’s Health Protection Advisory Committee, the National Toxicology Program Board of Scientific Counselors, the Board of Directors for Clean Production Action, and as associate director for the Agents of Change in Environmental Justice Program.
