As Colorado experiences more frequent extreme weather events, prolonged drought and loss of biodiversity because of a changing climate, farmers and scientists are developing more resilient and sustainable practices to mimic what Mother Nature has been doing for thousands of years.

Liz Carlisle, associate professor of environmental studies at the University of California-Santa Barbara and co-author of a new study published in the science journal Frontiers, said agroecological farming can create tightly connected cycles of energy, water and nutrients, if farmers get the resources they need.

"If we want to have a more sustainable food system, we really need to invest in that next generation of farmers and their development of knowledge," Carlisle urged. "And really think of them as the most important resource in farming."

Most of today's farms rely on fossil fuel-based inputs such as chemical fertilizers and pesticides, and soil is essentially just a place to stand up crops. This new approach prioritizes a living, healthy soil and aims to replace nonrenewable chemicals with people who know how to tap into natural ecosystems.

Carlisle pointed out new farms planted in wooded landscapes would look a lot like an actual forest. There would be multiple layers of crops, including trees. Farming on Colorado prairie lands could include regenerative grazing patterns created by native bison and other herbivores.

"Agroecological farming systems are really trying to work with nature -- and the services that nature provides, in terms of pest control and fertility -- rather than working against nature," Carlisle explained.

Over the past century, as family farms have been swallowed up by large corporations, farming in the U.S. has trended in the opposite direction. Carlisle noted people with deep ties to their lands have been replaced by chemical-centered practices in an effort to lower labor costs, and entire rural economies have paid the price.

"It's worth investing a little bit more of our tremendous wealth as a society in the people that do that critically important work," Carlisle contended. "And the landscapes that they are caring for."

On Tuesday, 20 Colorado officials sent a letter to the state's congressional delegation protesting six cuts to public lands management in the new tax and spending bill signed into law by President Donald Trump.

John Clark, mayor of Ridgway, said the elimination of river and climate data programs, which are essential to managing the Colorado River Basin and forecasting drought, will put additional burdens on food producers.

"If our farmers and ranchers don't have accurate data about exactly what the situation is with the snow pack and what's happening with the climate, how can they be prepared for each growing season?" Clark asked.

Five active wildfires have burned more than 22,000 acres on Colorado's Western Slope. The letter urged state representatives to reject any additional cuts to the U.S. Forest Service's Community Wildfire Defense Grant Program or other mitigation efforts. Republicans have argued cutting the size of government is necessary to eliminate waste, fraud and expenditures they claim are unsustainable.

Officials are also calling out a provision in the new law they believe undermines local decision-making by forcing oil and gas leasing on public lands. In addition, the law creates new barriers for clean energy leases on public lands, a move Clark worries will lead to the loss of good-paying jobs.

"If we discourage clean energy on public lands, that's going to severely impact our alternative energy workforce," Clark pointed out. "If we can't do wind and solar on public lands, it disincentivizes clean energy all across the state."

Officials are also asking members of Congress to fully fund the National Park Service to ensure proper staffing and maintenance. Clark argued standing up for lands owned by all Americans is essential to preserving Colorado's iconic natural landscapes and rural economies.

"Our economy is hugely dependent on people coming in to visit us and eat at our restaurants and experience these beautiful outdoor environments," Clark emphasized.

A Wisconsin nonprofit is working with farmers in Southeast Wisconsin to educate communities about the importance of agroforestry, with plans to establish its first urban site in Milwaukee.

The Michael Fields Agricultural Institute has planted more than 400 trees across three sites this year, in partnership with the Savannah Institute. The sites include a community garden and two farms.

Iris Lee, owner of Lee Hemp Farms in Burlington, said agroforestry collaboration is breathing life back into her nearly 50-year-old organic family farm.

"You plant and design things that go together," Lee explained. "That will help not only humans but the animals and nature and bugs."

Agroforestry integrates trees, shrubs and perennial plants into crop and livestock systems. Lee noted one of the project's goals is to raise awareness of the practices and their larger connection to food systems, climate change and communities. The sites will also be used for educational demonstrations.

Community members and project participants helped Lee plant a trail of more than 100 trees in April, from hazelnut and elderberry, to Juneberry and pawpaw trees. They have already grown two to three feet, and she anticipates the berry trees will yield results first. Lee added she even loves talking to her trees and emphasized the physical and mental health benefits of agroforestry.

"Growing something is therapeutic," Lee observed. "To be one with nature -- meaning you know where things come from that you put in your body -- anybody that is concerned about the food and their health, to grow something is to build upon a better human being."

Nolan Burkard, research technician for the nonprofit Michael Fields Agricultural Institute, said diversifying food systems in this way is a growing area of interest for small farmers. Through agroforestry, they can also improve soil health and local climate resilience.

Burkard emphasized it requires long-term investment to get there.

"It takes quite a while for trees to grow up and start fruiting or provide their benefit," Burkard acknowledged. "That's why this project is so important because it is such an investment to plant trees."

Burkard added the institute is accepting applications until July 26 for an urban site in Milwaukee. The selected site will receive $15,000 and planning support to aid in designing it.

Despite the elimination of a handful of alternative energy tax incentives in the new federal budget, Iowa corn farmers will benefit from one that was extended.

Tax breaks and rebates encouraging investment in solar and wind power in Iowa were eliminated in the federal spending plan. However, the Trump administration extended an incentive enabling farmers in Iowa to produce more corn. The Hawkeye State is the nation's top corn producer, much of which is used to produce ethanol.

Chris Bliley, senior vice president of regulatory affairs for the biofuel trade organization Growth Energy, said grain-based fuels burn cleaner and are more environmentally friendly.

"The credit actually goes for production of lower carbon fuels that are used for transportation," Bliley explained. "It includes on-road fuels as well as sustainable aviation fuel. And so, the lower in carbon, the higher the credit."

The Trump administration has made efforts to extract more fossil fuels, which it said will move the U.S. toward energy independence.

Lawmakers in Iowa and neighboring Midwest states have introduced their own tax incentives for biodegradable jet fuel, which Bliley noted will create economic benefits for ag producers.

"To remain competitive, plants in Iowa and Nebraska and throughout the Midwest are investing in some of these key projects to lower their carbon intensity," Bliley observed.

The commercial airline industry is aiming for net-zero carbon emissions by 2050, according to the International Air Transport Association, which could continue to benefit Iowa farmers who provide corn for ethanol production.
