Growing Pains: The Future of Farmland in Idaho

As the population rises rapidly in Canyon County and nearby areas, the Treasure Valley faces a difficult future: can Idaho balance housing demand and economic development while protecting the state’s most productive agricultural land? As development continues to push westward, many local leaders, farmers, and researchers fear that new housing and commercial projects could permanently reshape the future of Idaho’s agricultural communities. According to local studies and interviews, the question has long since moved beyond whether growth will occur and has shifted to how it can be managed without sacrificing our precious farmland. While we reshape the landscape, Idaho may also be reshaping the future of our local food production.

Research from Boise State University found that 68,823 acres of agricultural land were converted to development between 2001 and 2016 as the population of Idaho increased. While 68,823 acres may sound like an insignificant amount in a state spanning 53 million acres, researchers found that 26% of the land that was lost was classified as nationally significant farmland, meaning it was among the most productive agricultural land in the country. Idaho has consistently been ranked among the fastest-growing states since the early 2000’s, placing increasing pressure on agricultural land throughout the Treasure Valley as farmers face growing incentives to sell to developers. Between 2017 and 2022 Idaho lost an additional 2,119 farms and a total of 144,000 acres of working farmland, according to USDA Census of Agriculture. While not all this land was necessarily converted into development and housing, researchers and agricultural leaders acknowledge population growth as a major driver of farmland loss.

Nowhere is this tension more visible than in Nampa, Idaho. Once a primarily agricultural community, this quaint city has become one of the fastest-growing areas in the state, with new developments spreading along the city’s edges. While driving along the new houses on Franklin near the Amalgamated Sugar Factory, it’s easy to see exactly where houses and farmland meet. It is impossible to miss the boundary being formed between two worlds. For some Idahoans, growth has brought new opportunities and economic investment; for others, it has raised concerns about the long-term future of farmland that is ingrained in the identity of Canyon-County.

Supporters of continued development in the Treasure Valley area argue that growth is inevitable and necessary. As thousands of new residents move to Idaho each year, communities face increasing demand for housing, schools and businesses. New developments create jobs, expand local economy, and provide housing opportunities for growing populations. Nampa alone has grown 3%-5% consistently for the last 6 years. As more people come to the area and buy homes and spend their money here, growth continues to increase the need for space and homes. For many landowners, selling agricultural property can offer financial stability in an industry increasingly challenged by rising costs, fluctuating markets and unpredictable weather conditions which provides the land needed to build more homes. Some residents believe that there can be a balance between economic growth and preserving our farms. Local farmers markets, family-owned businesses and community-supported agricultural programs continue to draw support from residents who value locally grown food and a strong agricultural economy. Many people in Nampa make a conscious effort to shop locally and support locally owned farms in a market saturated with national chains and billion-dollar corporations. For these residents, farmland represents more than pre-developed land, it is our food source, it’s our economic opportunity and cultural identity. As development continues to surge across the Treasure Valley, the challenge becomes finding accommodation for growth without losing the land and resources that have defined the region for generations.

Unlike housing, farmland cannot simply be recreated after it’s lost. The soil, irrigation infrastructure and growing conditions often take decades, and in some cases centuries to return to productive farmland. Much of the Treasure Valley’s farmland uses extensive irrigation networks that have been built over generations, allowing crops to thrive in Idaho’s high desert climate. Once farmland is turned into roads, houses and business, it is increasingly difficult to return the soil to productivity. This is what makes the issue of growth urgent: growth can occur elsewhere, but agricultural resources cannot be brought back.

Along Franklin Road, the border between house and farmland continues to shift, the question facing Nampa is how communities choose to manage growth. As Idaho sees new residents and opportunities, local leaders, farmers and residents must decide what parts of their region’s agricultural heritage are worth preserving for the future.

Boise State University’s team FARMPrES or Farmland Protection for Ecosystem Services, is working on giving our community the tools to map out our futures. Carolyn Koehn joined the project in 2022 specializing in spatial sciences and uses geographic information systems to analyze the effects of urban development as well as how farmland serves the communities ecosystem. By Identifying patterns in comparable counties, she provides insightful strategies to help our preserve our way of life. Carolyn says, “We can inform people about farmland protection adaptations and strategies that may work for them based on what has worked in similar places.”(Boise State University).

As development continues westward, the future of the Treasure Valley’s farmland remains uncertain. The fields that surround communities like Nampa are more than vacant lots waiting for machines to descend; they are an intrinsic part of the regain economy, food systems, and identity. The challenge is no longer whether growth will occur, growth is here. The challenge now is to preserve our resources and manage the growth we face. We must play an active role in the preservation of our future.
