You asked, we answered: What transboundary water issues does cotton production bring, and how do they affect the environment?

You care about sustainable textile choices. Cotton is natural, yet it pulls water across borders. It changes ecosystems, communities, and global water security. Read on for clear facts and expert insights to help your decisions.

🔍 Water Use: The Shared Lifeblood of Cotton Regions

Cotton needs a lot of water. It uses around 256 billion m³ each year (Chapagain et al., 2006, Ecological Economics). Its water comes in three parts:
• Green water: Rainfall stored in soil (~39%)
• Blue water: Irrigation from rivers and groundwater (~42%)
• Dilution water: Water that absorbs pollution (~19%)

Most cotton grows in water-scarce areas like Central Asia (Uzbekistan), India, Pakistan, and China. In these regions, rivers like the Amu Darya and Syr Darya cross national borders and serve many countries.

🚩 Highlight: The Aral Sea lost 60% of its area between 1960 and 2000. Cotton irrigation pulled water away, harming the ecosystem and local lives (Glantz, 1998; UNEP, 2002).

Tips to Reduce Water Impact:
• Choose cotton with water-saving certifications (e.g. Better Cotton Initiative).
• Support brands that use drip or sprinkler irrigation. These techniques cut water waste—even if they are used by less than 1% globally (Postel, 1992).
• Favor clothing made from cotton grown in rain-fed areas, which reduces irrigation demands.
• Ask for integrated water resource management plans that cross borders to balance use and save nature.
• Seek transparency about the water footprint in cotton products.

🔍 Carbon Emissions Linked to Water and Cotton Production

Water practices affect carbon emissions too. Pumping groundwater uses energy and adds greenhouse gases. Pollution from fertilizers and pesticides forces extra water treatment, raising carbon costs. Expert A.K. Chapagain notes that water footprints must join carbon footprints to show true environmental costs (Chapagain et al., 2006).

🔍 Chemical Inputs: Polluting Shared Waters

Cotton farming depends on agrochemicals that can harm water quality. Up to 25% of the world’s insecticides and 10% of herbicides go on cotton fields (Textile Exchange, 2023). These chemicals find their way into rivers that cross borders, affecting downstream communities and biodiversity. The 19% dilution water shows extra water needed to handle this pollution.

Tips:
• Support organic farming or integrated pest management to lower chemical runoff.
• Encourage regional cooperation for monitoring and controlling pollution.
• Choose brands with strong sustainability policies regarding chemical use.

🔍 Recycling Cotton & Water: Closing the Loop

Recycling cotton fabrics saves water and limits pollution. Producing recycled cotton can use up to 90% less water than new cotton. Still, Textile Exchange reports that fiber recycling rates remain below 15%.

Tips:
• Choose recycled cotton or secondhand clothing.
• Support brands investing in closed-loop recycling technologies.
• Advocate for policies that reduce textile waste and ease water pressures.

❓ FAQ

Q: How do transboundary water conflicts arise from cotton farming?

A: Cotton irrigation uses rivers and aquifers shared by many countries. Upstream water withdrawals for cotton can lower water levels downstream. This drop harms ecosystems, spurs shortages, and can create tensions—just like the Aral Sea crisis, where Central Asian nations compete over waters of the Amu Darya and Syr Darya.
