You asked, we answered: How much water does cotton really use in the US, and what does it mean for sustainable choices?

We know you care. You choose fibers that hurt less. Cotton is one of the most used fibers. Here are clear facts and expert views. We list tips and data from trusted sources.

🔍 Water Use: Cotton and Water Consumption in the US

Cotton needs water. It does not drink more than other crops. The ICAC shows that 1 kg of cotton fiber—enough for one T-shirt and one pair of jeans—uses on average 1,931 liters of irrigation water and 6,003 liters of rainwater around the world (Better Cotton, 2023). Yet, in the US, water use changes with place:

• In the Southeast, US farmers use about 234 liters of irrigation water per kilogram.
• In the West, growers can use up to 3,272 liters per kilogram.

Local traits matter. Regional climate, irrigation methods, governance, and water shortage shape water use. Two out of three US cotton crops grow with rain alone (US Cotton Trust Protocol, 2024 Annual Report).

US experts measure water use efficiency. They monitor how much water each extra yield needs. On irrigated farms, this metric has improved by 14% since 2015. The target is 18% by 2025 using smart irrigation methods (Trust Protocol).

🚩 Water Use Highlights

• 2/3 of US cotton is grown with rain. No irrigation is needed. Cotton shows natural drought strength.

• In the US West, irrigation uses 14 times more water than in the Southeast. Geography shapes water impact.

💧 Actionable Tips for Sustainable Cotton Water Use

• Support brands that use Trust Protocol cotton. They track and better water use on farms.
• Choose cotton from rainfed regions or farms with proven water methods. This eases water pressure.
• Push for new irrigation ideas. Drip systems and soil moisture sensors save water.
• Ask brands for data. Demand transparency on cotton sourcing and water impact.
• Learn more about local water issues in cotton areas. Use this to guide your textile picks.

❓ FAQ: Is cotton the most water-intensive crop in the US?
No. Cotton’s water need per kilogram is moderate. Other crops, such as rice or alfalfa, need more water. Most cotton in the US is rainfed. Irrigation efficiency grows with new tech and better practices.
