Corn Farmers Upend Tradition to Reduce Air Pollution

Kathmandu is one of the most polluted countries in the world--a title once caused by the excess smoke produced by brick creation in the city. However, after a 2015 earthquake destroyed much of the old technology used to fuel the brick industry, leaders took to leveraging updated technology with an increase in energy and production efficiency.

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.

A benefit corporation called Burlap & Barrel brings together social enterprise work with quality products through the ethical production and distribution of single-source spices. The founders of Burlap & Barrel learned from previous business attempts and ethical quarrels to form a passion project that focuses on the quality, not quantity, of the spices.

Official in Bangkok, Thailand unleashed a small fleet of drones to deal with the hazardous levels of air pollution plaguing the city. The drones were outfitted with canisters capable of spraying water and a "non-hazardous chemical spray." The pilot project successfully reduced air pollution by small amounts.

Many herders are adapting to climate change by adopting farming. In the wake of severe droughts in recent years, herding communities in Ethiopia have expressed increasing interest in farming as a way to secure additional income. The non-profit organization, Farm Africa, helps herders to make the transition into farming by educating and assisting them with technical matters, such as irrigation, as well as aiding with financing and finding markets.

In Arizona, the use of drones as farming technology is gaining traction. While still in the early stages, drones have shown to help with field mapping and data collection on things like crop conditions, water quality, and infestations. In an area that has been experiencing a 2-decade drought, these drones are able to help identify more precisely the water needed for soil.

The Women’s Collective is a nonprofit that works with more than 10,000 subsistence farmers in the Indian state of Tamil Nadu to promote food security using millets, a crop resilient to drought and climate change. For Pavitra, one of those farmers, she began cultivating the ancient grains in 2015 and now has more than enough food to feed her family year-round. However, there’s a lack of public investment in millet production and machinery. And there’s no unified effort to create demand for millets: Some state governments lead the charge and in other states, it’s led by grassroots organizations.

After being known as a polluted mining town, politicians, scientists, industry officials, and residents of Sudbury, Ontario, were able to come together to restore its land. After 40 years and $33.5 million, they are about halfway through recovering about 200,000 acres of land. So far, they’ve been successful at restoring air quality, neutralizing soil to allow for replanting, and restocking lakes with fish. While some locals think the mining companies should have done more, the collaborative spirit could be a model for other communities looking to improve the environment.

Novva’s data center in West Jordan, Utah, uses recirculating pipes with refrigerant to cool its servers. This method uses significantly less water than the typical method, evaporative cooling.

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.
