Short answer
When designing products or systems that consume or impact water, assume a more severe future scarcity scenario than commonly projected, and prioritize solutions that address fundamental demand reduction and pollution prevention, not just supply management.

This paper argues that current projections for clean water scarcity by 2050 are underestimated due to the unaddressed impacts of population and economic growth on water demand, resources, and pollution. This resource management research insight is drawn from a 2019 study published in npj Clean Water. Using Review and critical analysis of existing reports and projections., researchers explored how this design variable affects real-world outcomes. The key design takeaway: When designing products or systems that consume or impact water, assume a more severe future scarcity scenario than commonly projected, and prioritize solutions that address fundamental demand reduction and pollution prevention, not just supply management.
Uncontrolled population and economic growth significantly increases global clean water scarcity by 2050

Key Findings
- 01The 2018 UN World Water Development Report's projection of 6 billion people facing clean water scarcity by 2050 may be an underestimation.
- 02The effects of population growth, economic growth, and unequal growth/accessibility on water scarcity are underrated in current projections.
- 03Relying solely on 'nature-based solutions' without regulating demography and economy, limiting pollution, and preserving aquifers is insufficient.
Application
Design takeaway
When designing products or systems that consume or impact water, assume a more severe future scarcity scenario than commonly projected, and prioritize solutions that address fundamental demand reduction and pollution prevention, not just supply management.
How to apply
When designing a new agricultural irrigation system, consider not just water efficiency, but also the long-term population growth in the region and its potential impact on water availability, leading to designs that promote water-saving crops or alternative water sources.
Project actions
- 01When designing a product or system that uses water, research the long-term water availability in your target region, considering population and economic growth projections.
- 02Focus on designing solutions that reduce overall water demand, not just improve efficiency, as demand will likely increase significantly.
- 03Consider the 'cradle-to-grave' water footprint of your design, including manufacturing and disposal, in light of increasing scarcity.
Method & Evidence
Variables
Strengths & Limitations
Strengths
- +Challenges conventional, potentially optimistic, projections of water scarcity.
- +Emphasizes the critical, often overlooked, role of population and economic growth as root causes.
- +Advocates for a more holistic approach beyond just technological fixes.
Limitations
This paper is a theoretical critique, not an empirical study. It doesn't offer specific design solutions but rather a re-evaluation of the problem's scale. Its call for 'regulating demography and economy' is a policy challenge, not a direct design task.
Reliability & validity
As a critical review, the reliability depends on the rigor of the authors' analysis of existing reports and data. Its validity comes from its logical argumentation and the consistency of its claims with observed global trends in resource consumption and population growth, though it doesn't present new empirical data.
Think critically
How might designers contribute to 'regulating demography and economy' or 'enforcing clear rules to limit pollution' through their product or system designs, even if these are primarily policy challenges?
Design Principles
"Sustainable resource management requires addressing root causes of demand and pollution, not just symptoms, especially in the face of exponential growth factors."
Understanding the drivers of resource scarcity, like clean water, is crucial for designers to develop sustainable solutions. This insight highlights the need for systemic changes beyond just technological fixes, emphasizing policy and behavioral regulation in resource management.
What This Means for Your Design
The problem of not having enough clean water in the future is probably much worse than we think, mainly because the world's population and economy are growing so fast, and we're not doing enough to control how much water we use or pollute.
How to use in your project
- 1.When analyzing the impact of your design on resource management, cite this paper to argue that water scarcity is a more pressing issue than commonly reported, justifying the need for your water-saving solution.
- 2.Use this paper to support your research into the 'environmental impact' of your product, specifically regarding water consumption and pollution, linking it to global trends.
- 3.Discuss how your design addresses the 'unequal growth, accessibility and needs' mentioned in the paper, particularly if your project focuses on a specific community or demographic.

Paragraph starter
According to Boretti and Rosa (2019), the projected clean water scarcity by 2050, affecting nearly 6 billion people, is likely an underestimation. They argue that the exponential impacts of uncontrolled population and economic growth on water demand, resource depletion, and pollution are severely underrated in current global assessments. This highlights the urgent need for design solutions that not only improve water efficiency but also fundamentally reduce demand and prevent pollution, acknowledging a more severe future scarcity scenario than commonly presented.
