Action Alert: Hold Congress Accountable for the Big Ugly Bill

Healthier Future for Wisconsin

Protecting the Land that Sustains Us

From farm fields to forests, prairies to wetlands—Wisconsin’s land shapes our health, our water, and our future. Clean Wisconsin works to protect and restore these landscapes through sustainable practices, conservation efforts, and bold climate solutions.

The Groundwork for a Healthier Wisconsin

The land beneath our feet connects everything—our drinking water, food systems, wildlife, and climate resilience. But rapid development, pollution, and unsustainable land use are putting these systems at risk.

Conventional agriculture, which covers nearly 30% of Wisconsin, plays a major role. Fertilizer and pesticide runoff pollutes groundwater, soil erosion depletes nutrients, and methane from livestock fuels climate change. Meanwhile, we’ve lost over half our wetlands—natural infrastructure that filters water, prevents flooding, and stores carbon.

Protecting Wisconsin’s future means protecting its land—by advancing conservation, supporting sustainable farming, and preserving natural areas that defend against climate extremes.

How We’re Protecting Wisconsin’s Land

From protecting wetlands to rethinking farming, Clean Wisconsin is working on the ground to protect what matters. We champion practical, science-backed solutions that support people, ecosystems, and the climate—all rooted in the land beneath our feet.

Supporting Sustainable Agriculture

We partner with farmers to reduce emissions, improve soil health, and keep pollution out of our water. With the right tools and support, agriculture can become a powerful climate solution.

Promoting Resilient Crops

Perennial crops like Kernza, hazelnuts, and aronia build healthier soil, resist drought, and offer new market opportunities for farmers.

Integrating solar into farmland

Solar farms offer Wisconsin farmers steady income, healthier land, and a way to power rural communities. With over 1,000 megawatts of new solar needed each year, integrating solar into farmland is key to reaching our climate goals.

Protecting Wetlands & Natural Areas

Wetlands absorb stormwater, filter water, reduce flooding, and provide essential habitat. We advocate for wetland protection and work to restore these ecosystems across the state.

Building a Roadmap to Net Zero for Farmers

To meet Wisconsin’s climate goals, we must transform how land is used. Our Natural Climate Solutions Roadmap helps align farming, forestry, and conservation with carbon-cutting strategies.

Key Challenges We Must Address

Wisconsin’s land is under growing pressure. Pollution, outdated practices, and policy gaps threaten its health—and ours. To protect our water, climate, and communities, we must confront the root causes of land degradation and fight for smarter, more sustainable systems.

Nitrate Pollution

Fertilizer and manure runoff contaminates groundwater—especially in areas with porous soils. Nitrate pollution poses serious health risks and costs families thousands just to access clean drinking water.

Soil Erosion & Runoff

Monocropping and bare fields lead to erosion and nutrient loss. Only a small fraction of fields use protective practices like cover crops or conservation tillage.

Waste from Industrial Agriculture

CAFOs (concentrated animal feeding operations) produce immense volumes of manure, which can contaminate waterways and release harmful methane emissions.

Economic & Policy Barriers

Conservation practices are underfunded. Most subsidies still support polluting systems, while land costs and limited support push out young and new farmers.

A Generational Shift in Farming

With the average Wisconsin farmer now 56 and many nearing retirement, the future of farming hangs in the balance. High land prices and input costs make it difficult for new and young farmers to take over. As a result, rural communities risk losing both innovation and a new generation of land stewards.

Our Land FAQs

Why does land use matter for climate and water?

Land use affects everything from carbon storage to runoff. Sustainable practices reduce emissions, protect drinking water, and keep ecosystems healthy.

What role do wetlands play?

Wetlands absorb floodwaters, trap pollution, and store carbon. Restoring wetlands is one of the most cost-effective ways to boost climate and water resilience.

Can agriculture help solve climate change?

Yes. With regenerative practices, farming can shift from being a top emitter to a powerful climate solution.

How can I help?

Support sustainable farmers, restore native landscapes, reduce lawn chemicals, and advocate for land-friendly policies at every level. And join our Action Network to be alerted when your voice can make a difference.
