Rising Water Stress Is a Sourcing Risk

Article key points: 

• Water stress is already constraining factory output in major sourcing regions, increasing supply chain risk.
• Constrained production from water scarcity translates directly into fill rate gaps, margin pressure, and supplier instability.
• Regulatory scrutiny on water use and withdrawal is tightening across many major sourcing regions, expanding compliance risk.
• Technology to reduce water use and improve supplier performance exists today.
• Mapping and measuring water stress exposure helps companies protect revenue and build supply chain resilience.

Every tier of the supply chain depends on water. Precipitation and irrigation for raw materials, wet processing for fabric, and various steps throughout the finishing process are just a few places where water use is concentrated. 

The global textile and apparel industry consumes an estimated 93 billion cubic meters of water annually, roughly equivalent to the water needs of 5 million people. This piece focuses on water stress—defined as the inability to meet human and ecological demand for freshwater due to constraints on availability, quality, or access. Flood risk and wastewater discharge are distinct issues covered in separate upcoming articles.

Supply chains are already experiencing water stress

Water stress doesn’t announce itself suddenly, like a flood. It builds slowly through growing periods of drought that result in real human costs along with commercial risks like tightening allocations, rising costs, reduced production volumes and shrinking margins. The increase in water stress means organizations without insight into their supply chain’s water status can be taken by surprise when water stress reaches a tipping point.  

Your supplier base is operating in water-stressed territory

When mapping over 100,000 apparel factories against World Resources Institute Aqueduct water stress data, Planet Tracker found that nearly two-thirds of those factories sit in China, Turkey, Bangladesh, and India, and also carry medium-to-high or higher stress scores. 

As climate change reduces precipitation predictability, available freshwater will decline at the same time as production volumes rise. Global manufacturing water demand is projected to be 400 percent higher in 2050 than it was in 2000. By 2050, Brazil and Vietnam are each projected to move up a full water stress category. Turkey is projected to cross into high stress, its score increasing by roughly a third. 

Natural fiber producers carry acute water stress exposure

Tier 4 producers—farmers and growers who supply raw natural fibers—sit at the point where water stress hits first, and hardest. Unlike factories, they cannot reschedule production or substitute inputs when water is unavailable. Blue water — the surface water and groundwater held in lakes, rivers, aquifers, and basins — is already under stress across nearly three-quarters of global cotton-producing regions. Yet cotton’s blue water footprint rose 19 percent between 1972 and 2018, reaching an unsustainable 70.9 km³ per year.Raw material production accounts for 60 to 80 percent or more of a finished garment’s total blue water use across fiber types. Most brands have mapped water risk only in supply chain Tiers 1 and 2, and Tier 4 remains largely invisible. 

What water stress does to your supply chain

Water stress has far-reaching implications for global supply chains, from impacting the communities where facilities operate and their residents, to squeezing corporate margins and threatening companies’ long-term feasibility. 

Three key ways water stress impacts your business:

• Water shortages reduce output and impact revenue targets: Water-constrained factories reduce output or halt wet processing entirely. Even modest disruptions at the frequency seen in water-stressed manufacturing clusters translate into revenue shortfalls for manufacturers.

• Rising water costs compress brand margins: Suppliers facing water scarcity pay more for access, invest in treatment technology, or absorb regulatory penalties. With supplier margins often in the low single digits, they often have no choice but to pass cost increases to their customers. A one percent revenue hit to a supplier on a five percent operating margin reduces its profits by 20 percent. When this happens, brands see their own costs increase and margins fall.

• Regional supplier concentration makes switching suppliers unrealistic: Water stress often affects entire production clusters simultaneously. When a basin tightens, many factories face the same constraint at the same time. Switching suppliers to mitigate disruption when it occurs becomes difficult when every supplier faces the same issue.

Water regulation is tightening in every major sourcing region

Tightening regulation on water use and withdrawal is already underway where most consumer goods manufacturing is concentrated. 

• China enacted its first national water conservation law in May 2024, restricting water-intensive projects in stressed regions, mandating advanced water-saving equipment, and establishing legal liability for violations. A nationwide water resource tax launched in 2024. Water conservation is now a national security priority under the 15th Five-Year Plan (2026–2030). 
• Vietnam’s revised Law on Water Resources, effective July 2024, strengthened enforcement authority over water withdrawal and industrial water use.
• The EU’s Water Resilience Strategy, adopted in June of 2025, targets a 10 percent efficiency improvement by 2030 and expands water disclosure requirements under the EU’s Corporate Sustainability Reporting Directive (CSRD) and the Corporate Sustainability Due Diligence Directive (CSDDD). For brands with European operations or investors, the CSDDD explicitly covers environmental due diligence in supply chains, which includes water-related supply chain disruptions. Failure to account for these creates legal exposure.

In the U.S., investor demand is accelerating regardless of regulatory direction: The Carbon Disclosure Project (CDP) reports that requests for corporate water data doubled in a single year. 

Investing in water risk management improves margins and protects supply

The World Bank has warned that water scarcity could reduce GDP by up to 6 percent in some regions by 2050. For brands sourcing heavily from those regions, that is a direct sourcing risk. 

The Organisation for Economic Co-operation and Development (OECD) estimates the economic cost of an average drought event today is at least twice as high as in 2000, with costs projected to increase by at least another 35 percent by 2035. Severe droughts can reduce fluvial trade volumes by up to 40 percent. 

When it comes to water stress, early mitigation efforts cost far less than lost production, strained supplier relationships, and emergency logistics.

Water risk is financially material, yet it remains under appreciated. In 2023, companies reporting to CDP disclosed that water stress risk could total $77 billion. CDP estimates total potential financial impact could reach $339 billion. The link to bottom-line performance is direct: Peer-reviewed research finds that higher water vulnerability is significantly associated with lower corporate financial performance. Yet Planet Tracker’s analysis of disclosures and earnings transcripts from 29 major apparel brands found water risk represented just one percent of all investor mentions. 

The technology to reduce water vulnerability exists today 

Under the International Finance Corporation (IFC)’s Partnership for Cleaner Textile (PaCT) program, over 450 textile plants in Bangladesh saved 35 billion liters annually by deploying wet-process best available technologies—including wastewater recycling, reverse osmosis units, and optimized dyeing machinery. One mill cut water consumption from 360 liters per kilogram of denim to 10 liters. 

CDP estimates that integrating water stewardship into risk management could unlock approximately $1.4 trillion in value across supply chains. That reflects the value of avoiding costs and improving reliability.  

The risks of not managing water risk in your supply chain:

• Companies that don’t invest in water risk management are likely to face higher disruption and cost as sourcing costs rise and water-stressed regions become less reliable production bases.
• China, Vietnam, and the EU already have enforceable water standards. Non-compliant suppliers expose buyers to liability and production delays under national laws.
• The CSDDD covers environmental due diligence in supply chains. Failure to address water-related harm creates direct legal exposure.
• Companies that ignore water stress risk reputational damage when scarcity forces suppliers to compete with local communities for scarce resources.

Four steps you can take now to address supply chain water risk

Water stress risks are high, but mitigating them is possible. Many companies haven’t taken action on mitigating risk from water stress because they can’t see where it’s happening in the supply chain, and don’t have enough information to quantify the business impact. Smart and responsible businesses are getting data on what’s happening in their supply chains, and are taking  four steps toward uncovering and addressing water stress.

1. Map your supply chain. Know which suppliers operate in high water-stress basins—not just by country, but by river basin, production process, and regulatory environment. The most exposed sites are those with high water stress combined with high revenue concentration and high water vulnerability. 
2. Engage your suppliers. Water management belongs in the sourcing conversation alongside cost, quality, and capacity. Work with suppliers to understand their water vulnerability relative to the water stress in their region. Track water usage at your suppliers along with tracking steps suppliers have taken to lower their water vulnerability. Using widely adopted assessments like the Higg Facility Environmental Module (Higg FEM), you can obtain primary data on water usage. 
3. Report on risks. Value chain water reporting lags far behind GHG reporting even while supply chain risk is concentrated in water use. It’s necessary to quantify the production impact of constrained water access to make informed decisions about where to invest in resilience and projects to decrease water vulnerability. Measuring water usage and risk in your supply chain creates accountability, enables comparison against the cost of intervention, and builds the internal business case for action at scale. Worldly Axion combines facility-level primary data with basin-level stress indicators to show where risk is concentrated.  
4. Act on your exposure. Buyers that support suppliers in implementing water efficiency measures to lower water vulnerability aren’t just managing downside risk—they’re building production capacity and stronger supplier relationships. Reward suppliers that collaborate with you to help you meet your own goals. Work with suppliers on processes most impacted by water stress and align on cost-effective mitigation plans. 

Water stress is an emerging sourcing constraint

As water stress intensifies, companies without mapped exposure and mitigation programs are likely to face escalating disruptions while better-prepared competitors maintain supply chain continuity. Leading companies are already collaborating with their suppliers to identify water stress and reduce water vulnerability, so they can protect workers, production volumes, margins, and business growth.
