Key Findings

  • 01Two-thirds of the global population (4.0 billion people) experience severe water scarcity for at least one month per year.
  • 02Nearly half of those affected live in India and China.
  • 03Half a billion people face severe water scarcity year-round.

Application

Design takeaway

Incorporate water conservation strategies and materials with low water footprints into product design, especially for regions with high water stress.

How to apply

When designing products, research the water scarcity levels in the target market and explore ways to reduce the product's water demand during manufacturing and use.

Project actions

  • 01Investigate the water footprint of materials you are considering for your product.
  • 02Explore design strategies that reduce water usage during the product's operational phase.
  • 03Consider the end-of-life disposal and its potential impact on water resources.
03

Method & Evidence

AimTo assess global blue water scarcity on a monthly basis and quantify the number of people experiencing severe water scarcity.
MethodQuantitative analysis based on global hydrological models and water footprint data.
ProcedureThe study modelled water availability and consumption on a monthly basis across high spatial resolution grids globally. They then calculated water scarcity by comparing the demand for blue water with its availability.
ContextGlobal freshwater resource management and human impact.

Variables

IVMonthly water availability and consumption.
DVDegree of water scarcity experienced by populations.
CVSpatial resolution of analysis, definition of 'blue water'.
04

Strengths & Limitations

Strengths

  • +High spatial and temporal resolution of the analysis.
  • +Quantifies the scale of the water scarcity problem globally.

Limitations

The global average data might not reflect the specific water scarcity conditions in a very localized area. The study focuses on blue water, and other water sources might be relevant.

Reliability & validity

The study's reliance on global models and data introduces potential uncertainties. However, the high resolution and monthly analysis enhance its validity compared to annual assessments. Replication would involve using different hydrological models or updated datasets.

Think critically

How might the increasing frequency and severity of water scarcity, potentially exacerbated by climate change, further influence design priorities and material selection in the future?

05

Design Principles

"Design for water efficiency by minimizing water consumption throughout the product lifecycle."

This research underscores the pervasive nature of water scarcity, a key sustainability challenge. Designers must consider the lifecycle of their products and the water footprint associated with their production, use, and disposal. Understanding regional water stress is crucial for developing equitable and sustainable solutions.

06

What This Means for Your Design

Lots of people don't have enough water for at least one month every year, so designers need to think about how their products use water.

How to use in your project

  • 1.Use this data to justify the need for a water-efficient design solution in your Design Proposal or Evaluation.
  • 2.Quantify the water scarcity in your target market to support your design choices.
  • 3.Discuss the sustainability implications of your design in relation to global water challenges.

Paragraph starter

The pervasive issue of global water scarcity, with 4 billion people facing severe shortages for at least one month annually (Mekonnen & Hoekstra, 2016), necessitates a design approach that prioritizes water efficiency. This research highlights the critical need to consider the water footprint of products throughout their lifecycle, from material sourcing and manufacturing to end-use and disposal, particularly in regions with high water stress.
