The Nexus Approach to Managing Water, Soil and Waste under Changing Climate and Growing Demands on Natural Resources

  • Rattan Lal


The human population has increased more than a thousand times from 2–20 million at the dawn of settled agriculture about 10–12 millennia ago to 7.2 billion in 2013. It is projected to reach 9.6 billion by 2050 and ~11 billion by 2100 (UN in World population prospects: The 2012 revision. UN Department of Economic and Projection Section, New York, 2012)
