Study Notes
Water Resource Overview
- Water covers about three-quarters of Earth's surface.
- Water is essential for all life (plants, animals, humans).
- Water is a renewable resource that returns to the water cycle after use.
- The total amount of water on Earth might not seem to be a problem, but fresh water is limited (3.5%).
- Global population growth and increasing demand are causing water pollution and waste.
- Access to fresh water where and when needed is a major issue.
Water Stress
- A global map shows areas with high water stress.
- Water stress is a significant issue facing many regions.
Water Use
- Water use is diverse, encompassing domestic, agricultural, industrial, and in-stream (e.g., navigation, recreation).
- Irrigation agriculture uses over 70% of global water, with industry accounting for an additional 20%.
- Domestic and municipal uses comprise the remaining 10%.
- Water use patterns vary greatly by region.
Increasing Water Demand
- Water is a fundamental natural resource.
- Most fresh water comes from rivers, lakes, and underground aquifers.
- Seawater can be used after desalination.
- Global water use has increased substantially over the past century (seven times).
Factors Driving Increased Demand
- Rising global population is increasing demand.
- Improved living standards often correlate with increased water usage in homes.
- Increased irrigation for food production contributes significantly.
Water Conservation
- Water conservation is the careful use and protection of water resources.
- It's crucial for achieving sustainable water use.
- Conservation practices include improved agricultural irrigation systems, integrating surface and groundwater use, minimizing water waste, and adjusting industrial and domestic practices.
- Industries can reduce water usage through water recycling and treatment.
Sustainable Water Use
- Water sustains life, including ecological systems.
- Its importance extends to ecosystem support, economic development, and community well-being.
- Sustainable water use focuses on responsibly managing water resources to avoid degradation of the hydrologic cycle and ecological systems.
