  2. A Few Water Facts • Population growth means 50% increase in water needed by 2030 • >70% of all fresh water used in agriculture • Water tables in parts of Mexico, Middle East, India, China falling by 1 meter/year

  3. Salt susceptible area (20%) Salt affected area (42%) Worldwide Irrigated Area (300 million hectares) Worldwide Agricultural Area (5,169 million hectares) Source: Flowers and Yeo,( 1997) Aust. J. Plant Physiol. 22:875-884. Salt Build-up Growth Zone

  4. Environmental Stresses: The Major Factors for Yield Reduction Loss to diseases, insects, weeds: 10% Actual yield: 21% Crops NOT Reaching Genetic Potential Tolerance Genes Control Yield Stability Loss to environmental stresses: 69% “Tolerance” Genes Allow Yield to Be less Reduced by Stress From J.S. Boyer (1982) Science 218: 443-448.
