Bengaluru: Famed
mountain retreats such as Mussoorie, Darjeeling and Kathmandu may soon
face acute water distress--with a demand-supply gap already as vast as
70% in some towns--new research shows.
A series of 10 studies across 13 towns
located in the Hindu Kush Himalayan (HKH) region across India, Pakistan,
Nepal and Bangladesh has found mismanagement of water and climate breakdown.
“The urban Himalayas, they are running dry,” said Anjal Prakash, research director and adjunct associate professor at the Bharti Institute of Public Policy
at the Indian School of Business (ISB), Hyderabad. “Most of their water
sources are from springs and the springs are on the decline because of
the complex combination of climatic and non-climatic factors.”
Ten of Asia’s largest rivers originate in the HKH stretch of mountain
ranges running from Afghanistan in the west to China in the east.
Yet, the gap between demand and supply of water here may double by
2050, the research has found. The gap in eight of the surveyed towns is 20%-70% with a high dependence on springs, ranging between 50% and 100%.
The 10-studies series, work on which was
done over two years, was included in a special issue of the
international peer-reviewed journal Water Policy published on March 1, 2020. Prakash, along with David James Molden, director general of the Nepal-based International Centre for Integrated Mountain Development (ICIMOD), edited it and summed up the key takeaways in an editorial accompanying the studies.
Rapid urbanisation and climate emergency to blame
Currently, 3% of the total HKH population lives in larger cities and 8% in smaller towns, as per the editorial.
By 2050, more than 50% of the population of the region will be living
in cities, adding to the stress on water resources, as per projections
used in the series.
One of the studies
that makes the same point about rapid urbanisation, blames poor water
governance, lack of planning, poor tourism management during peak season
as well as climate breakdown for the water stress.
Another study
from the Indian Himalayan towns Mussoorie and Devprayag highlights how,
despite significant tourism, they lack rainwater harvesting, stormwater
management and proper sewage systems.
While demand has grown, supply has been
hit by changing rainfall patterns and reduced availability of spring
water. “When we think of climate change in the mountains, we think of
melting of the glaciers,” said Molden. “While that is a critical
problem, the problem we miss is the rainfall and the springs.”
In the coming years, rainfall extremes are predicted to rise, along with floods, according to the latest reports from the Intergovernmental Panel for Climate Change (IPCC), the UN
body set up to assess the science on climate change. While some places
are expected to become wetter, others will become drier. Erratic
monsoons are already damaging crops, as IndiaSpend reported earlier, and could increase the number of hungry people in India.
“The climate and water story is simple,” explained Amir Bazaz, a senior climate change researcher at Indian Institute of Human Settlement (IIHS),
Bengaluru. “The story is connected to precipitation. Climate change
will change precipitation patterns and all your water bodies get water
from precipitation as there is no other source.”
In the mountains, that water body is the
spring--overexploited by increasing populations and not adequately
recharged due to changing rainfall patterns.
What also complicates the search for a
solution is that springs have not been mapped yet, nor is their
seasonality understood, said Prakash. “The cities [in the mountains] are
not ready for looming climate risks that IPCC reports have projected,”
he said.
Of India’s 12 Himalayan states, Assam,
Mizoram and the union territories of Jammu & Kashmir and Ladakh are
the most vulnerable to climate change, as IndiaSpend reported earlier.
Worst affected: Migrants, poor & women
Experiences of water stress in the
countries studied varied greatly over the years and along class, caste
and gender lines. Rich households in Kathmandu spend 38.2% less on water
than poor households, one of the studies in the series has found. Nearly 20%
of Kathmandu’s poor households do not have access to formal water
supply, such as that managed by civic bodies. These homes depend on
expensive informal water supply systems such as private water tankers.
The poor thus stand to gain if the water
economy shifts from the informal to the formal. “There are vast
inequalities and differential water rights for people,” said Prakash.
Within households, in most cases, the burden of filling water falls on
women, IndiaSpend had earlier reported from the plains of Odisha and Rajasthan. A similar trend has been documented in Nepal’s mountain regions.
Rural to urban migrants are another
vulnerable group. In 2018, there were 28 million new displacements
associated with conflict and disasters across 148 countries and
territories, according to the Global Report on Internal Displacement released in May 2019.
So far, India has no system to count its climate migrants but it ranks fifth among the countries most vulnerable to the impacts of climate change, among 181 studied, as IndiaSpend reported in December 2019.
“Migrants coming into the city are disadvantaged, women are disadvantaged. The poor quite often are disadvantaged,” said Molden of ICIMOD. “That is really where the crisis lies.”
Need for better water governance
The series uses the example of
Darjeeling in West Bengal--a town that lies in a water-rich region--to
highlight potential solutions. Darjeeling’s problem is mainly due to
mismanagement of water by the local municipal body as well as
insufficient investments in overhauling old British-era water systems,
the study said.
Answer to the water stress then is efficient local bodies and local solutions, the study
suggests. More appreciation is also needed for women’s multiple roles
in water management and how they could be part of the planning and
decision-making processes.
“We need solutions and need investments but they need to be mountain
specific and they need to take into consideration existing knowledge
sources,” said Molden.
