Urban Farming Key in Fight Against Hunger and Climate Change
The urban farms sprouting up and across cities around the world aren't just feeding mouths—they are "critical to survival" and a "necessary adaptation" for developing regions and a changing climate, according to a new study.
Urban farms—which include plain ol' allotments, indoor vertical farms and rooftop gardens nestled amongst busy streets and skyscrapers—have become increasingly popular and important as the world's population grows and more and more people move to cities.
The United Nations predicts that by 2030, two-thirds of the world's population will be living in cities, with the urban population in developing countries doubling. That's a lot of mouths to feed.
The new paper, published in the journal Earth's Future and led by the Arizona State University and Google, finds that this expected urban population boom will benefit from urban farming in multiple ways.
As the Thomson Reuters Foundation explained from the study, "Urban farms could supply almost the entire recommended consumption of vegetables for city dwellers, while cutting food waste and reducing emissions from the transportation of agricultural products."
According to the study, urban agriculture can help solve a host of urban environmental problems, from increasing vegetation cover (thus contributing to a decrease in the urban heat island intensity), improving the livability of cities, and providing enhanced food security to more than half of Earth's population.
After analyzing multiple datasets in Google Earth Engine, the researchers calculated that the existing vegetation on urban farms around the world already provides some $33 billion annually in services from biocontrol, pollination, climate regulation and soil formation.
The future of urban agriculture has even more potential, the researchers found.
"We project potential annual food production of 100–180 million tonnes, energy savings ranging from 14 to 15 billion kilowatt hours, nitrogen sequestration between 100,000 and 170,000 tonnes, and avoided storm water runoff between 45 and 57 billion cubic meters annually," the authors wrote.
"In addition, we estimate that food production, nitrogen fixation, energy savings, pollination, climate regulation, soil formation and biological control of pests could be worth as much as $80–160 billion annually in a scenario of intense [urban agriculture] implementation."
Others have praised urban farming for its many benefits.
"Urban agriculture won't resolve all food production and distribution problems, but it could help take pressure off rural land while providing other advantages," wrote environmentalist Dr. David Suzuki.
He cited an example of how one patch of Detroit land, where 12 vacant houses were removed to grow food, "has supplied almost 200,000 kilograms of produce for 2,000 local families, provided volunteer experience to 8,000 residents and brought the area new investment and increased safety."
"Local and urban agriculture can also help reduce greenhouse gas emissions and recycle nutrient-rich food scraps, plant debris and other 'wastes,'" Suzuki continued. "Because maintaining lawns for little more than aesthetic value requires lots of water, energy for upkeep and often pesticides and fertilizers, converting them to food gardens makes sense."
Writer and former Vancouver city councillor Peter Ladner also wrote in The Urban Food Revolution: Changing the Way We Feed Cities, "When urban agriculture flourishes, our children are healthier and smarter about what they eat, fewer people are hungry, more local jobs are created, local economies are stronger, our neighborhoods are greener and safer, and our communities are more inclusive."

Over the last month, I've seen a number of opinion articles attacking electric vehicles (EVs). Sadly, this comes as no surprise: now that the Biden administration is introducing federal policies to accelerate the roll out of electric vehicles, we were bound to see a reaction from those that oppose reducing climate changing emissions and petroleum use.
The majority of EVs sold in 2020 were models with a starting price (Manufacturers Suggested Retail Price) under $40,000 and only a fifth of models had a starting price over $60,000.
On Friday, China set out an economic blueprint for the next five years, which was expected to substantiate the goal set out last fall by President Xi Jinping for the country to reach net-zero emissions before 2060 and hit peak emissions by 2030.
The Great Trail in Canada is recognized as the world's longest recreational trail for hiking, biking, and cross-country skiing. Created by the Trans Canada Trail (TCT) and various partners, The Great Trail consists of a series of smaller, interconnected routes that stretch from St. John's to Vancouver and even into the Yukon and Northwest Territories. It took nearly 25 years to connect the 27,000 kilometers of greenway in ways that were safe and accessible to hikers. Now, thanks to a new partnership with the Canadian Paralympic Committee and AccessNow, the TCT is increasing accessibility throughout The Great Trail for people with disabilities.

Alexa Fernando<p>This partnership also comes at a time when access to outdoor recreation is more important to Canadian citizens than ever. <a href="https://www150.statcan.gc.ca/n1/daily-quotidien/200527/dq200527b-eng.htm" target="_blank" rel="noopener noreferrer">Studies from the spring of 2020</a> indicate that Canadian's <a href="https://www.bnnbloomberg.ca/moneytalk-mental-health-during-covid-19-1.1567633" target="_blank" rel="noopener noreferrer">mental health has worsened</a> since the onset of social distancing protocols due to COVID-19. </p><p>The <a href="https://www.mayoclinic.org/diseases-conditions/coronavirus/in-depth/safe-activities-during-covid19/art-20489385" target="_blank" rel="noopener noreferrer">Mayo Clinic</a> lists hiking, biking, and skiing as safe activities during COVID-19. Their website explains, "When you're outside, fresh air is constantly moving, dispersing these droplets. So you're less likely to breathe in enough of the respiratory droplets containing the virus that causes COVID-19 to become infected."</p><p>TCT leadership took this into consideration when embarking on the accessibility project. McMahon explains that there has never been a more important time to bring accessibility to the great outdoors: "Canadians have told us that during these difficult times, they value access to natural spaces to stay active, take care of their mental health, and socially connect with others while respecting physical distancing and public health directives. This partnership is incredibly important especially now as trails have become a lifeline for Canadians."</p><p>Together, these organizations are paving the way for better physical and mental health among all Canadians.
