Amidst our recovery from the catastrophic fallout of COVID-19, collectively advancing the role we play in building a sustainable future and more sustainable food systems will be paramount.
We believe U.S. dairy is part of the solution.
U.S. dairy farmers have a legacy as environmental stewards, continually innovating to improve their footprint by adopting groundbreaking eco-forward practices that enable them to produce 60% more milk with 15.7 million fewer cows, using 65% less water and 90% less land than they did 76 years ago. That's 76% less manure and a 63% smaller carbon footprint.
Fast forward to today and our continued, documented progress is that the environmental impact of producing a gallon of milk has shrunk significantly from 2007, requiring 30% less water, 21% less land and a 19% smaller carbon footprint.
In Wisconsin, Crave Brothers Farm uses a computer-controlled anaerobic digestion system to burn the gas produced by the manure of 2,100 dairy cows to generate enough renewable energy to power both the Crave brothers' farm and their Farmstead Cheese factory, as well as 300 nearby homes.Click here to see more...
In Connecticut, dairy farmers Amanda and Matt Freund use their recipe for composted cow manure “stew” to mold nutrient-rich, 100% biodegradable CowPots for planting seed. The CowPots are used to grow produce and flowers at their family’s retail store, Freund’s Farm Market & Bakery, and are sold to home gardeners, commercial growers and retailers across the country.
In Washington, at Royal Dairy, Austin Allred uses hungry worms to break down the bacteria in his farm’s wastewater, which is then used to irrigate local corn and hay crops. The worms also produce a casting that serves as a high-quality compost for locally grown apples, hops and various other commodities.
And that’s just some of the imaginative thinking and purposeful innovation being employed by so many visionary U.S. dairy farmers and local businesses who believe the world is better off with dairy cows in it.
A recent modeling study published in the Journal of Dairy Science assessed the impacts of completely removing dairy cows from the U.S., thus removing dairy from all American diets. The results showed a lack of presumed environmental benefits and a notable threat to human health. Availability of essential nutrients for people’s health would significantly decrease, as dairy’s dense nutrient package is not easily replaced by fruits, vegetables, nuts and pulses.
It’s no longer a question of either/or when it comes to achieving sustainability in supply chains and global food production. Both plants and animals play a critical role in the health of people and the planet and it will take collaborative, inclusive, multi-stakeholder efforts and partnerships to achieve collective, meaningful impact.
Despite accounting for less than 2% of U.S. GHG emissions, U.S. dairy understands and is embracing its role in further reducing the GHG emissions coming from the agrifood sector. But how?
First, in 2020, the U.S. dairy industry set Environmental Stewardship Goals, pledging to achieve carbon neutrality, optimize water usage through recycling, and improve water quality through the management of manure and soil nutrients by 2050. Sustainable, on-farm practices, including regenerative agriculture and manure management, can result in the reduction of methane and nitrous oxide, greenhouse gas emissions and land degradation, providing rich habitat for wildlife, as well as the production of renewable energy.
To reach the finish line, we must find ways to bring new types of manure and wastewater management systems — along with other groundbreaking sustainable on-farm practices — to everyone in the industry. Widespread implementation and deployment will pack the collective punch needed to make a profound impact. If the gas from the manure of 2,100 dairy cows can power a farm, a cheese factory and 300 homes, imagine how much electricity could be generated with the manure of 9 million cows.
Second, the Innovation Center for U.S. Dairy launched the Net Zero Initiative, also in 2020. Regenerative agriculture is central to U.S. dairy’s net-zero efforts, as this industry-wide program aims to make sustainability more affordable and accessible to farmers across the nation’s 34,000 dairy farms by helping them develop meaningful innovation, leverage new technologies, adopt economically viable eco-friendly practices and create new markets and products.
