This study provides a modern, accessible framework for mapping the US Corn Belt using the Landuse and Agricultural Management Practices web-Service (LAMPS). It quantifies corn cropping patterns and temporal changes, aiding research on food, feed, biofuel, and water security.
Area of Science:
- Agricultural Science
- Geospatial Analysis
- Environmental Science
Background:
- The
- Corn Belt
- is a loosely defined region in the US Midwest, lacking modern, flexible mapping tools.
- Previous studies mapped historical Corn Belt boundaries, but a contemporary spatial and temporal framework is needed.
Purpose of the Study:
- To develop a flexible and accessible framework for mapping the 21st-century US Corn Belt.
- To quantify space-time changes in corn cropping patterns using new tools.
Main Methods:
- Utilized the Landuse and Agricultural Management Practices web-Service (LAMPS) to estimate average corn area (Fraction of corn, Fc) per county in the contiguous 48 USA states (2010-2016).
- Developed modified areal Fc to map the Corn Belt at varying intensity levels.
- Mapped irrigated areas and temporal changes in Fc.
Main Results:
- Generated detailed reference maps of the US Corn Belt for the 21st century.
- Identified a contiguous Midwest Corn Belt surrounded by scattered southern and eastern regions.
- Quantified temporal shifts in corn cropping patterns and mapped irrigated zones.
Conclusions:
- The developed framework provides a modern, data-driven approach to defining and analyzing the US Corn Belt.
- Mapped patterns offer valuable insights for research on food, feed, biofuel, and water security.
- The flexible mapping tool enables better understanding of agricultural land use dynamics.
