The Business of Burps: Scientists Smell Profit in Cow Emissions

As climate change continues to advance, its impact on farmlands has become more pronounced and increasingly devastating. Farmers and researchers in both South Africa and Nepal are working towards solutions to problems specifically related to climate change. Centered on developing technology, these farmers have found success with NASA satellite imagery as well as local clinics.

Across the country, projects that mine landfills for reusable metals and soils are underway. Can such mining prove profitable enough to spur similar efforts on a grand scale? So far, some projects have seen profits while others have not. But as society increasingly values pollution and greenhouse gas reduction, incentives for refuse mining can only grow.

In California’s wildfire-prone Sierras, forest managers are turning to an ancient, if not quite intuitive, tool: more fire. In 2019, the Forest Service will manage 250,000 acres with controlled burns and “mechanical thinning,” using equipment to take out small trees. Though such plans face some hurdles, states across the country are adopting them, reducing wildfire severity while often benefiting ecosystems.

From North Carolina to California, states and cities are taking a new approach to fines and fees – people are having their charges dismissed, warrants for minor offenses cleared, and many municipalities are actually saving money by spending less on collections. With a system that was built because it provided cities and states with revenue, there has been a realization that it disproportionately targets communities of color and often keeps people stuck in cycles of debt. With this national awakening, resources and networks are being created so other places can implement the same change.

To help essential workers navigate the notorious traffic of Bogota, the city built over 50 miles of an emergency bike network. The plan was in place before the arrival of coronavirus but the execution was sped up to meet the demands of increased bike usage. Other measures were also put into place to make the roads more bike and pedestrian-friendly: Reduced speed limits for cars, a 20 percent increase in private parking for bikes, and a bike registration system to deincentivize bike theft. Efforts to expand bike lanes not only eased traffic, they also helped relieve pressure on the overcrowded bus system.

Philanthropies are funding “tough tech” startups that are developing technologies to cut greenhouse gas emissions and mitigate the effects of climate change. Since 2014, the nonprofit Prime Coalition has channeled more than $24 million from wealthy donors and foundations to 10 ventures focused on that goal. Not all of their investments, though, have paid off. Yet, some of these initial investments could lead to widespread solutions to the world’s climate crisis.

As climate changes causes seawater to flood land and increase the salt content in soil, farms in Scotland and the Netherlands are experimenting with using the saltwater to grow food. Seawater Solutions is growing crops called halophytes that have a high-salt tolerance and can be eaten or used as material for cosmetics and biofuels. And the Salt Farm Foundation has shown that potatoes, cabbage, and tomatoes can grow in saltwater. These projects can labor intensive, but seawater irrigation could be a viable climate adaptation solution.

In Kenya, like other countries in the world, deforestation is the major driver of tree cover loss. To solve this, a local startup called Seedball Kenya has developed the seedball technology whereby seeds of indigenous tree and grass species are coated with charcoal waste mixed with nutritious binders then thrown like balls into the planting grounds.

A startup is making buildings more eco-friendly by converting their energy needs from oil and gas to electric heat pumps. BlocPower is a Black-owned clean tech startup that provides a no money down lease option, making it financially accessible.

London charges higher-emission vehicles every day they enter the city center, called the Ultra Low Emission Zone, on top of the already existing London Congestion Charge for non-electric vehicles to enter the zone. Since the charges were implemented, the city has seen an increase in electric vehicle adoption and improved air quality.
