Countries affected

1. United States 

Impact: The U.S. is one of the most monoculture-dependent countries, especially with corn and soybeans. Over 50% of farmland is dedicated to just two crops. Leads to: Soil degradation (Midwest “Corn Belt”) Dead zones in rivers and the Gulf of Mexico due to fertilizer runoff Heavy reliance on GMO and pesticide-intensive farming📍Hotspots: Iowa, Illinois, Indiana, Nebraska

2. Brazil 

Impact: Massive monoculture farming of soybeans, sugarcane, and cattle feed. Has led to: Deforestation of the Amazon Soil erosion in the Cerrado region Water pollution from agrochemicals📍Hotspots: Amazon Basin, Mato Grosso, Cerrado region

3. India 

Impact: Heavy monocropping of rice, wheat, and cotton, especially post-Green Revolution. Issues include: Groundwater depletion (Punjab, Haryana) Increased pest resistance Farmer debt and crop failure risks📍Hotspots: Punjab, Haryana, Maharashtra
