Water Crisis
CONTENT
• Introduction
• Supply & Demand
• Physical & Economic scarcity
• Effects on environment
• Water scarcity in India
Introduction
• Water scarcity is the lack of fresh water resources to
meet water demand.
• It affects every continent and was listed in 2019 by
the World Economic Forum as one of the
largest global risks in terms of potential impact over
the next decade.
• The essence of global water scarcity is the geographic
and temporal mismatch between freshwater demand
and availability.
Supply & Demand
• The total amount of easily
accessible freshwater on Earth, in the
form of surface
water (rivers and lakes)
or groundwater), is 14.000 cubic
kilometers
• Of this total amount, 'just' 5.000
cubic kilometers are being used and
reused by humanity.
• Scarcity as a result of consumption
is caused primarily by the extensive
use of water in agriculture/livestock
breeding and industry.
Physical & Economic scarcity
• Physical water scarcity results from inadequate
natural water resources to supply a region's
demand.
• Economic water scarcity results from poor
management of the sufficient available water
resources.
Global physical and economic water scarcity
Effects on environment
• Increased salinity, nutrient pollution, and the loss
of floodplains and wetlands.
• Depletion of freshwater
resources
Groundwater
Glaciers
• More than half of the
Earth's wetlands have been
destroyed and have
disappeared.
• Climate change
Water Scarcity: India’s Silent Crisis
• According to a NITI Aayog report, India will run out
of ground water in the next 10 years. Close to 40
percent of India will not get access to drinking water
by 2030.
All eyes on Jal Shakti ministry as India's
water crisis deepens
• The solution is better conservation of water and
moving away from heavy reliance on
groundwater for agriculture.
• The centre should lower GST for rainwater
harvesting equipment.
• Giving tax breaks for wastewater and
incentivizing drip irrigation is also the need of the
hour.
• The government had also promised that it will
implement recycling 100 percent liquid waste.
