  • 1. SCIENCE EXHIBITION BY RAHUL.MS XI-A3 AVRS
  • 2. TOPIC OF THE ASSIGNMENT:- PRESENT DAY ISSUE OF WATER SCARCITY in the world AND METHODS OF CONSERVATION
  • 3. WATER SCARCITY  Water scarcity is the lack of sufficient available water resources to meet the demands of water usage within a region.  It currently affects around 2.8 billion people around the world, on all continents, at least one month out of every year and more than 1.2 billion people lack the access to clean drinking water.
  • 4. Water scarcity can be a result of two mechanisms: ◦ Physical water scarcity & ◦ Economic water scarcity where physical water scarcity is a result of inadequate natural water resources to supply a region's demand, and economic water scarcity is a result of poor management of the sufficient available water resources
  • 5. ISSUE OF WATER SCARCITY in India As a country that receives copious rain, water scarcity in India is mainly attributed to human factors such as:    India's population have steadily risen since independence. Absence of comprehensive family planning, and lack of education, spurred this. This in turn has increased the demand for water. But, no government has so far been able to equate the difference of water distribution - more than 50% of the country's population lack access to safe drinking water. Corruption and lack of planning and coordination are also blamed as factors of water scarcity in India. Many projects to supply safe drinking water are often stuck in red tape. More than 80% of water needs of the country is met by exploiting the ground water resources of India. This has aggravated the depletion of water table, and led to an unprecedented water shortage.
  • 6. Per Capita Water Availability in INDIA  The per capita availability of water in the country is 1545 cubic meters as per the 2011 CENSUS. The average annual per capita availability of water in the country, taking into consideration the population of the country as per the 2001 census, was 1816 cubic meters which reduced to 1545 cubic meters as per the 2011 census, denoting that the per capita water availability in the country is reducing progressively due to increase in population.
  • 7.  Also there are reports that demand for water in India would rise dramatically to about 833 cubic kilometers in 2025 and 899 cubic kilometers in 2050 due to increase in population, rapid urbanization and a growing GDP with significant lifestyle changes.

  • 11. MAP SHOWING THE STATES HIT BY WATER SCARCITY
  • 12. ISN’T THERE ANY WAY TO SOLVE THIS PROBLEM ??????
  • 13.  Well, there is a solution always to resolve these problems ◦ to save our future from getting destroyed and give to our children……… We can act upon it smartly and quickly for the future. Government and NGO’s are already in action and have taken steps to prevent this situation.
  • 14. COUNTER MEASURES FOR THIS WASTAGE OF WATER  Community led initiatives  Government led initiatives ◦ National Water Mission ◦ Exploitation of Ground water  Rainwater harvesting  Farm ponds
  • 15. Community led initiatives  With support from government and UNICEF, villagers in Palve Budruk, located in the drought-prone Parner Block in Ahmednagar district of Maharashtra, developed a catchment plan covering 1,400 hectors – that’s over 80% of the land available. The system has three check dams, 20 canal bunds, two small percolation tanks linked to the main tank and 19 village ponds.
  • 16. Government led initiatives  National Water Mission The Mission Document for National Water Mission was drafted by the Ministry of Water Resources through consultative process with full involvement of State Governments, concerned Central Ministries, Non-Governmental Organizations, academicians and other stakeholders.
  • 17. FIVE GOALS IDENTIFIED IN THE NATIONAL WATER MISSION ARE: Comprehensive water data base in public domain and assessment of the impact of climate change on water resources;  Promotion of citizen and state actions for water conservation, augmentation and preservation;  Focused attention to vulnerable areas including overexploited areas;  Increasing water use efficiency by 20%;  Promotion of basin level integrated water resources management.
  • 18. EXPLOITATION OF GROUND WATER  The Central Ground Water Authority (CGWA) has notified 82 areas (Districts, Blocks, Mandals, Talukas, Municipalities) for regulation of ground water development. In these areas, installation of new ground water abstraction structures is not permitted without prior specific approval of the Authority / Authorized officer. Moreover, proposals for setting up/expansion of ground water based industries including bottled water manufacturing units are forwarded by State Pollution Control Boards and Bureau of Indian Standards to CGWA for seeking No Objection Certificate (NOC) for ground water withdrawal.
  • 19. TWO STEPS TAKES FOR EXPLOITATION OF GROUND WATER  Rainwater harvesting - Rain water is accumulated and used for ground water recharge. This increases the ground water availability.  Farm pond - Farm ponds are constructed near the farming field. The rain water which runs off the ground are collected by these ponds. These ponds helps agriculture in dry lands.
