Marginal Land: Definition, Characteristics, and Potential Uses

What Is Marginal Land?

Marginal land refers to land with minimal agricultural or industrial value, often located in desolate areas or at the edge of deserts. It typically has poor soil quality and limited profit potential due to its remoteness from transportation infrastructure. Southwest states like Nevada and Arizona in the United States are known to have significant amounts of marginal land.

Key Takeaways

  • Marginal land has little to no agricultural or commercial value.
  • It may suffer from physical isolation, lack of water, steep slopes, or industrial pollution.
  • Biofuel production is a possible use for marginal land, as it could be utilized for biomass without displacing conventional crops.
  • Marginal land does not include areas designated for conservation purposes, such as state and national parks.

Understanding Marginal Land

Marginal land is characterized by its limited value, often referred to as "degraded," "idle," or "surplus" land, which cannot generate profits through crop production. This type of land may have been negatively impacted by human activities, like industrial pollution, or face challenges such as water scarcity and steep terrain.

Abandoned agricultural land and former human-used areas are examples of marginal land, distinguished by erosion, salinization, or low organic carbon content. It’s important to note that land’s marginal designation can change based on market values. If the value of a crop significantly increases, previously marginal land may regain its productivity.

Furthermore, a piece of land labeled as marginal in one region might not be considered as such in a different agricultural area. For instance, land suitable for less profitable crops in the highly productive American Midwest may be categorized as marginal, even though its soil characteristics are similar to those found in more profitable regions.

Potential Uses for Marginal Land

Marginal land can be utilized for specific purposes. For instance, it can serve as grazing areas for free-roaming livestock. Some propose the use of marginal lands for biofuel production, as it would allow biomass cultivation without displacing traditional crops or competing with farmland. Switchgrass, shrub willow, and giant miscanthus are potential plants suitable for this purpose.

However, it’s important to note that areas set aside for non-productive reasons, such as state and national parks, do not fall under the classification of marginal land.
