Design takeaway

Prioritize water-efficient design and resource allocation strategies that account for the accelerating depletion of groundwater resources.

How to apply

When designing systems or products that consume significant amounts of water, conduct a thorough water footprint analysis and explore opportunities for water reduction, recycling, or alternative water sources.

Project actions

  • 01When researching water usage for your design project, look for data that distinguishes between surface water and groundwater.
  • 02Consider the long-term implications of your design's water consumption on local and global water resources.

Method & Evidence

AimTo dynamically simulate global water withdrawal and consumptive water use, distinguishing between surface water and groundwater, and to analyze the human impact on terrestrial water storage.
MethodIntegrated hydrological and water demand modeling with a novel water allocation scheme.
ProcedureCoupled a global water demand model with a global hydrological model, incorporating a new irrigation scheme and reservoir data, to simulate daily water withdrawal and consumption from 1979-2010 using re-analysis products.
ContextGlobal water resource management and hydrology.

Variables

IVTime period (1979-2010), re-analysis products (ERA-Interim, MERRA), inclusion of human water use and reservoir operations.
DVGlobal water withdrawal, consumptive water use (surface water and groundwater), terrestrial water storage (TWS) anomalies.
CVHydrological model parameters, irrigation scheme dynamics, daily surface and soil water balance.

Strengths & Limitations

Strengths

  • +Global scale modeling provides a comprehensive overview.
  • +Distinguishes between surface water and groundwater use, a key advancement.
  • +Incorporates dynamic feedback between supply and demand.

Limitations

The global scale of this model means it might not capture very localized or specific water management practices. Your own design project might have more detailed local constraints.

Reliability & validity

The study validates its simulated withdrawals against national and subnational statistics and compares simulated TWS anomalies with GRACE observations, enhancing reliability and validity.

Think critically

Given the accelerating rate of groundwater depletion, what innovative design strategies can be implemented to shift reliance towards more sustainable water sources or drastically reduce overall water consumption in high-demand sectors?
