Water – a precious and finite resource

The world's water consumption rate is doubling every 20 years — twice as fast as the population growth rate. By 2025, water demand will exceed supply by 56%. Managing this precious and finite resource is a critical and urgent challenge. While there is theoretically enough fresh water on the planet to sustain the needs of its population, much of it is wasted, polluted and unsustainably managed. In addition, its uneven distribution means that while some parts of the planet have more than enough water, scarcity occurs elsewhere. In many areas, increasingly erratic rainfall is leading to repeating cycles of drought and flood. The critical need for water to sustain all aspects of human activity has driven us to inhabit floodplains and deltas close to rivers. Today 82% of the global population lives in these areas and are exposed to a high risk of flooding. This is further magnified by the impact of climate change. The need of the hour: to sustainably manage these risks and balance the various conflicting uses of water; for drinking supply, agriculture and industry, power production, navigation and the environment.

THE CHALLENGES

  • Ensuring reliable water supply for consumptive use, agriculture and industry
  • Minimising environmental impacts of water abstraction and use
  • Mitigating flood risk
  • Managing water infrastructure
  • Improving efficiency of water delivery

OUR APPROACH

At DHI, we strive to develop a robust understanding of the physical water environment as a precursor to any analyses influencing decision-making. We apply state-of-the-art modelling technologies and analytics to achieve this. We work with our clients and stakeholders to appreciate the water management issues that may affect their project outcomes. We develop solutions that are appropriate, cost-effective and environmentally responsible.

OUR SOLUTIONS

  • Watershed management
  • Rivers, dams and reservoirs
  • Flood management and forecasting
  • Groundwater management
  • Irrigation
  • Water quality and environmental impacts

THE ULTIMATE GOAL

SUSTAINABLE MANAGEMENT OF THE WORLD’S FRESHWATER RESOURCES
