Qualitative and Quantitative Water Scarcity Issues in Bihar,India

  2. 2. Water Quality and Quantity "Water quality and quantity is going to be the biggest challenge in coming years to human beings on planet Earth.......Many persons have survived without love, but none without water"
  3. 3. if lOur Life Style ??? If everyone on Earth continue our current life style, it would take more than 7 Earths to support human population by the end of this century.
  5. 5. Changes in the present century: GlaciersGangotri Glacier (NASA) g – Receding since 1870 when data gathering began – 1,147 meters melted away during the 61 years between 1936 andbetween 1936 and 1996 (19 meters per year)per year) – Receded 850 meters during theg 25 years between 1975 and 1999 (34 )meters per year)

  13. 13. Projection of Climate Change on Water Availability • The gross per capita water availability in Bihar will decline from about 1,950 m3/yr in 2001 towill decline from about 1,950 m /yr in 2001 to as low as about 1,170 m3/yr in 2050 • Bihar will reach a state of water stress before 2020 when the availability of clean water falls below 1000 m3 per capitabelow 1000 m per capita

  59. 59. Faced with Such a Complex and ExpansiveFaced with Such a Complex and Expansive Challenge, Where Do We Begin? Priorities 1. Control of indiscriminate ground water usage. 2. Match specific water demand to quality needed 3. Maximize use of reclaimed water at sitewater at site 4. Sustained resources for technology, training, infrastructureg 5. Enforce healthy land use policy 6. Attention on agriculture and industry 7. Emphasis on water education, water as ultimate human resource
