Key Findings

  • 01Global water use has increased sixfold in the last century and continues to grow.
  • 02Water demands are approaching or exceeding availability in many regions, exacerbating water scarcity.
  • 03Future water availability is influenced by complex environmental, social, economic, and political factors.
  • 04Consistent global water scenarios are needed for effective planning and investment.
02

Application

Design takeaway

Integrate water scarcity projections into the early stages of design and development to ensure long-term viability and resilience.

How to apply

When designing products or systems that have a significant water footprint, research regional water scarcity projections and incorporate water-saving features or alternative resource strategies.

Project actions

  • 01When choosing materials for your design, consider their water usage during production and lifecycle.
  • 02Explore how your design can reduce water consumption for the end-user.
  • 03Investigate the water availability in the region where your design will be used.
03

Method & Evidence

AimTo develop and assess global water scenarios for the 21st century to inform future development and investment decisions.
MethodScenario modeling and comparative analysis of global water models.
ProcedureThe Water Futures and Solutions (WFaS) initiative coordinated work with existing scenario efforts, utilizing shared socio-economic pathways (SSPs) and representative concentration pathways (RCPs). Three global water models (H08, PCR-GLOBWB, and WaterGAP) were employed to estimate and project regional and global water use, assessing the strengths, weaknesses, and uncertainties of different estimation methods.
ContextGlobal environmental and resource management, specifically focusing on freshwater resources.

Variables

IVFuture socio-economic pathways (SSPs) and representative concentration pathways (RCPs).
DVProjected regional and global water use and water scarcity levels.
CVThe three global water models (H08, PCR-GLOBWB, WaterGAP) used for estimation.
04

Strengths & Limitations

Strengths

  • +Utilizes established scenario frameworks (SSPs and RCPs).
  • +Employs multiple global water models for a more robust assessment.
  • +Provides a consistent framework for comparing water use projections.

Limitations

The global models used have uncertainties, and local conditions can vary significantly from global averages. Future socio-economic and political changes are hard to predict accurately.

Reliability & validity

Reliability is enhanced by using multiple models and established scenario frameworks. Validity is addressed by comparing different models and acknowledging uncertainties, though the predictive validity for specific future events remains a challenge due to the complexity of influencing factors.

Think critically

How might the socio-economic and political factors mentioned in the study lead to different water scarcity outcomes in various regions, and how can design adapt to these diverse futures?

05

Design Principles

"Design for water resilience by anticipating future resource constraints."

Understanding future water availability and demand is crucial for designers and engineers involved in sectors reliant on water, such as agriculture, energy, and urban development. These projections inform decisions about infrastructure, technology adoption, and policy, mitigating risks associated with water scarcity.

06

What This Means for Your Design

The world is using a lot more water than before, and by 2050, we might not have enough water for everyone, especially for growing food and developing countries. This means we need to be smarter about how we use water.

How to use in your project

  • 1.Reference this study when discussing the environmental context and resource availability for your design project.
  • 2.Use the findings to justify the need for water-efficient features in your design.
