Nature-Based Solutions in San Diego

Nature-based solutions are actions to help protect, sustainably manage and restore natural or modified ecosystems that address societal challenges while simultaneously providing benefits for people and the environment. As the most biodiverse county in the continental United States, San Diego County is well positioned to utilize nature-based solutions. These actions can help reduce greenhouse gas emissions and achieve societal co-benefits.

Nature-based solutions aim to enhance the natural function of ecosystems to provide multiple societal co-benefits such as improved public health through cleaner air and water as well as the availability of open space, improvements to habitat for wildlife and plants, flood risk reduction and other ecosystem services that enhance the resiliency of our environment. Natural and working lands are vital in the carbon cycle in San Diego and throughout California. Healthy ecosystems that include vegetation and soil microbes capture and store carbon from the atmosphere. In contrast, changes that alter or damage ecosystems, including land use modifications, deforestation and wildfires, can release sequestered carbon back into the atmosphere, accelerating the climate crisis. To balance between carbon stored and carbon released determines whether natural lands and ecosystems function as net sources or net carbon sinks. Protection of natural environments from land use and disturbances helps promote the functioning of forests, wetlands and oceans as carbon sinks that absorb more carbon than they emit.

San Diego has initiated multiple nature-based solutions projects already. However, the need to develop and scale up these projects is ever increasing as San Diego and California face impacts of the climate crisis. The United States Economic Development Administration’s Economic Integrator helped catalyze a nature-based solution project focused on upstream improvements to reduce runoff and debris deposited into San Diego’s stormwater infrastructure. This project helps mitigate the impact of flooding in the urban center while enhancing outdoor recreation and economic development for the County. The project focuses on Maple Canyon, nestled between Balboa Park and San Diego International Airport, a green space that buffers business with nature inside the urban core of San Diego. As flooding during storm events occurs, runoff and debris impact the downstream commercial enterprises, transportation networks and natural habitats. Restoration efforts have minimized flooding and stormwater runoff, helping protect vital urban infrastructure and important urban and natural landscapes.

As a coastal city, enhancing the resiliency of our coast is vital to managing climate change impacts such as sea level rise, coastal erosion and storm surges. Coastal wetlands throughout San Diego County are essential ecosystems that not only help with flood protection but are also some of the most productive ecosystems that play an integral role in the ecology of our watershed. Coastal wetlands are also considered “blue carbon ecosystems,” which include habitats like salt marshes and seagrass meadows that help capture and store more atmospheric carbon per acre than terrestrial forests. Nature-based solutions that preserve and restore these wetlands help build community resilience to the impacts of climate change by sequestering carbon and helping enhance the resiliency to sea level rise and coastal flooding. The Blue Carbon Collaborative, founded by the nonprofit organization Wildcoast, is a network of organizations working on the conservation, research and policy developments for blue carbon ecosystems and nature-based solutions. 

Only 10 percent of California’s original wetlands remain, yet they are some of the best ecosystems on the planet for taking carbon out of the atmosphere and storing it in the ground for a long time. Restoration of these wetlands provides an opportunity to enhance these ecosystems' production and utilize their potential as a natural climate solution. Aligning nature based solutions with the 30x30 plan to conserve 30 percent of our land and coastal waters by 2030 to protect biodiversity will expand access to nature while lessening the impacts of the climate crisis.

How to Celebrate the Holidays Sustainably in the time of COVID-19

If you’re scrambling for last-minute holiday gifts (like some of us), it can be tempting to give in to Amazon Prime delivery and the holiday deals at big businesses, throw the likely unethically and unsustainably made items in a gift bag, and call it a day. But with economic losses resulting from the pandemic, and continued impacts of climate injustices,it is even more important to shop ethically and sustainably this year.

If you’re scrambling for last-minute holiday gifts (like some of us), it can be tempting to give in to Amazon Prime delivery and the holiday deals at big businesses, throw the likely unethically and unsustainably made items in a gift bag, and call it a day. But with economic losses resulting from the pandemic, and continued impacts of climate injustices,it is even more important to shop ethically and sustainably this year.


With transportation accounting for 28 percent of total greenhouse gas emissions in the U.S. by economic sector in 2018, and an increase in package deliveries around the holidays, shopping at local, small-owned businesses with sustainably made or second hand gifts is one of the best ways to resist climate change and stimulate the local economy. If you choose to leave your house for holiday shopping, walking or biking to a small owned business is encouraged. In particular, we’re considering how we can best support small businesses owned by Black folks, Indigenous friends and People of Color. If there’s one thing we took from 2020, it’s that our actions are needed to continue showing up for racial and environmental justice.


With the recent rise in COVID-19 cases, shopping in person is not considered the safest option for folks. Many small businesses have gotten creative with local delivery and if you have friends or family who will be shopping in person this year, consider reaching out to them to arrange no-contact drop offs from your favorite local shops. If neither of those options are working out, consider getting gifts delivered to your loved ones from small businesses local to them, so you can save on emissions from shipping presents to them from where you are. In these uncertain times, we’re reminded that the health of our communities and the health of the planet are interdependent. Regardless of whether or not you’re leaving your house to get gifts, there are so many other ways to celebrate sustainably this holiday season--and for good reason. The EPA estimates that the American household waste increases by more than 25 percent between Thanksgiving and New Year’s Day for an estimated additional one million tons of wasted food, shopping bags and gift wrap per week! Along with buying items that are ethically and sustainably made, here are additional tips for a more conscious holiday celebration this year:


1) Say no to plastic and paper bags when buying presents

  • This one may be a little harder while reusable bags are not allowed in some stores, but many stores will allow you to bring them in as long as you bag your items yourself.

2) Rethink gift wrapping

  • If you don’t have gift wrap or bags leftover from previous years, instead of buying new ones, you can opt to use newspaper, reusable bags, reusable gift wrap (for a gift that really keeps on giving!), any leftover shopping bags or just skip the wrapping altogether! If you’re sending packages yourself, consider looking on websites like OfferUp, Buy Nothing or Nextdoor for free shipping boxes.

3) Aim for little to no food waste

  • In San Diego, we typically throw away 40 percent of food, which is higher than the national average. Instead of contributing to that already staggering number, we can be proactive about food waste this year and prevent an increase in methane emissions from adding to over overflowing landfills. We can do this by preparing “just enough” rather than way too much, distributing leftovers to friends, family and houseless folks, freezing leftovers we’re likely to eat and composting the scraps we don’t use while cooking.

4) Get creative for gift giving

  • Do-It-Yourself (DIY) gifts are even more popular this year as we’re spending most of our time at home. Think outside the box for a meaningful, hand-made gift that uses household items. Need inspiration? Pinterest always has great DIY ideas!

5) Gift intentional quality time to your quarantine partners

  • If you’re quarantining with someone you want to spend quality time with, like a friend or significant other, consider planning a thoughtful hangout or date at a COVID-safe place like your home or a park that isn’t crowded. Make it special with energy efficient LED string lights, games, plant-based and locally sourced food (if accessible) and holiday-themed sweaters and music!

6) Gift a donation on behalf of a loved one

  • A great alternative to buying people more things they likely don’t need is donating to a nonprofit organization on behalf of the person receiving the gift. You can even symbolically adopt an animal through the World Wildlife Fund, and the funds go towards programs to help conserve and protect that species.

7) And for last minute gift ideas…


Thanks for caring and reading this post. Individual actions add up and can make an impact reducing carbon emissions contributing to the climate crisis. Happy holidays!

Biking as a Solution to the Climate Crisis

The San Diego Climate Hub hosted its second quarterly event, Biking a Solution to the Climate Crisis, on Thursday, December 10. The San Diego community engaged in an interactive discussion about how bicycling is one of many solutions to help reduce our CO2 emissions, which exacerbate the climate crisis and contribute to climate injustices. 

The San Diego Climate Hub hosted its second quarterly event, Biking a Solution to the Climate Crisis, on Thursday, December 10.  The San Diego community engaged in an interactive discussion about how bicycling is one of many solutions to help reduce our CO2 emissions, which exacerbate the climate crisis and contribute to climate injustices. 

 

The free event included a presentation with speakers from the nonprofit organizations Bike San Diego, Climate Action Campaign, SanDiego350 and Sierra Club San Diego, and the panel was moderated by Denice Williams with Black Girls Do Bike and the San Diego County Bicycle Coalition.  After the panel there was a Zoom breakout session where fellow activists were able to get to know each other and share about their interest in biking.

San Diego is the eighth largest city in the nation yet ranks sixth for having the worst air pollution. Communities of concern, surrounded by freeways in San Diego, experience higher rates of asthma and pollution related-illnesses, and have a shorter lifespan than communities in other parts of the city.  This is an example of a climate injustice. More people who bike instead of drive dirty, gas vehicles can help reduce local air pollution, which was highlighted during the event. 

 

"Communities of color need to be prioritized for all sustainable transportation improvements that will ensure that they have more access to clean air and affordable transportation options,” said Bertha Rodriguez, the Assistant Organizer at Climate Action Campaign, who presented on Thursday.  “By centering equity and looking at biking through an intersectional lens, we can start breaking down the disparities caused by race, class, gender and ability in order to promote a more inclusive climate revolution."


The San Diego Climate Hub is a center, located in Hillcrest, to strategize, collaborate and build collective power to stop the climate crisis and advance climate justice in the San Diego region. The nonprofit members include Bike San Diego, Climate Action Campaign, SanDiego350, San Diego Coastkeeper and Surfrider Foundation San Diego County, and it’s managed by Hammond Climate Solutions. The purpose of the Climate Hub is to catalyze collaborative local and regional solutions to stop the climate crisis, and quarterly events are a way to bring together activists to share education, resources and people power to create a brighter future.  

The next quarterly Climate Hub event will be in partnership with the San Diego Green New Deal Alliance on February 23 at 5:30 p.m. More details will be available at www.sdclimatehub.org.
