Chapter 2. Water Availability: Spatial and Temporal Variability

This chapter covers the basics of how much water is available in different regions, with a focus on hydrologic variability, especially drought. We address questions like these:

  • How much water is available for human use, and how does this vary across the world?
  • How do floods and droughts affect water availability?
  • What can we learn about drought from the paleoclimate record?
