Too Much or Too Little Water in the
Himalayas - UNEP Press Release
Copenhagen,
Nairobi, Kathmandu, 11 December 2009 - Hundreds of millions of people in
the Hindu Kush-Himalayan region and in the river basins downstream are
being forced to adapt to a new reality: climate change.
Climate change is increasing uncertainty and the risk for extreme droughts
interspersed with extreme floods that are challenging food security,
housing, infrastructure, business and even survival.
Even hardy mountain populations, adapted for centuries to survival in
extreme environments, are undergoing events so unprecedented that their
traditional coping strategies are being overwhelmed by the events
unfolding.
These are some of the main findings of a new study released today at the
UN climate convention meeting in Copenhagen by the International Centre
for Integrated Mountain Development (ICIMOD), United Nations Environment
Programme (UNEP), and the Center for International Climate and
Environmental Research (CICERO).
The findings are based on five field teams in China, India, Pakistan and
Nepal who took part in this unique collaborative pilot study to look at
the realities facing mountain populations and hundreds of millions people
downstream.
The acute experiences of people in this region are living proof of the
pressures some societies are already enduring as a result of the onset of
climate change - adaptation here is not just a necessity but a question of
local communities' very survival," said Achim Steiner, UN Under-Secretary
General and UNEP Executive Director.
In Nepal, a country normally known as a country of water abundance,
extreme droughts in some cases lasting years have impacted large parts of
the country. People who can afford machinery respond by digging trenches
in the dry river beds. Now the trenches and tube wells have to be guarded
to protect them against those who cannot afford to get water this way,
leading to increased inequality and conflicts in the society.
In Assam and Bihar in India, embankments built to contain the Koshi River
have led to waterlogging, and even worse, cause catastrophic floods when
they suddenly burst as a result of improper construction and inadequate
maintenance. People who have settled closest to the embankments are the
most vulnerable and take the heaviest toll.
"Policies that determine people's access to resources when facing water
stress and floods are currently weak throughout the region, thus people
rely on their own innovations," said Andreas Schild, Director General of
ICIMOD. "Governments have to find ways to support improved livelihood
strategies, and increase people's influence in the governance of
infrastructure, such as embankments," he added.
For the impoverished, everyday activities are focused on immediate
survival, thus rendering the hope of developing long-term resilience and
economic development even more remote, says the report.
In some places, necessity has forced local farmers to sell off livestock
and land during droughts to pay short-term debts, to cope with elevated
food prices, or to rebuild destroyed housing - resulting among others from
extreme climate events and inadequate policies elsewhere in the world.
Traditional institutions, like the Gram in Chitral, Pakistan, help people
to manage scarce water resources in an equitable way. In Pakistan, a near
doubling of the population in just 40 years will also challenge the food
production, which is mainly based on irrigation from rivers fed by
meltwater from snow and glaciers in the mountains.
Social networks and cultures are an asset in dealing with the extremes,
such as the designation of women as water guards in Yunnan province in
China, to manage water conflicts.
Networks can also ensure that migrants find help, as in Chitral, Pakistan,
where kinship and traditional hospitality help fellow villagers re-settle
after catastrophes. But in some cases traditions can also challenge the
need for new ways to adapt.
In Assam, India, non-Mishing people are unwilling to use the
flood-tolerant housing techniques developed by the Mishing because they do
not wish to be associated with another caste.
Traditionally, many of the government policies in the countries of the
region have been sectoral in nature, such as the investments in irrigation
infrastructure in Yunnan. These investments, focused on increasing cash
crop production at the national level, have largely improved and
strengthened lowland communities' coping capacity and productivity - but
they have not helped the up-land communities in dealing with water stress,
as this was not their focus.
Similarly, road development in Nepal has increased market access and
thereby supported new livelihoods, but has destroyed many traditional
streams and wells, reducing local ability to cope with drought.
Restoration programmes following droughts have frequently simply
reconstructed buildings in high-risk flood zones, even new schools have
been constructed in high-risk flash-flood locations.
A chief finding of the report is the need for governments to prioritise
the development and improvement of national and regional policies to
provide better support for local adaptation against a more extreme
climate, helping to shift planning from acute survival towards long-term
resilience. Many of the countries in the region, such as India, have
assigned special institutions nationally to address disaster management.
"The report is ground-breaking in that it brings together best-practices
aimed at increasing adaptation and resilience from across borders in
Pakistan, India, Nepal and China," Mr. Steiner said. "If the world is to
deal decisively with climate change, we must also address the need for
programmes targeted towards adaptation strategies to build long-term
resilience. Local people already have to make choices daily, and
governments with adequate international assistance must step up their
efforts to support them in coping," he added.
The report comes as the result of a two-year pilot assessment in the
region, coordinated by ICIMOD, with partners from a range of institutions
in China, India, Pakistan and Nepal, supported by expertise from UNEP's
polar and cryosphere centre in Norway, GRID-Arendal, and the Norwegian
Center for International Climate and Environmental Research (CICERO).
The study was performed through field teams who successfully conducted
field investigations under challenging conditions in Chitral, Northern
Pakistan, the hills of Koshi Basin, Nepal, Koshi Basin flood plains in
Bihar, India, Brahmaputra flood plains in Assam, India, and in hill areas
in Mekong and Salween river basins in Yunnan, China. The study was
financed by the Norwegian and Swedish Governments.
Key Findings from the Report and Statistics on the Hindu-Kush Himalayan
region:
- Extreme climate events are destroying crops, depleting water resources,
causing losses in livestock, cropland, and agricultural productivity, and
destroying the meagre infrastructure present, thus reducing market access
and access to public services.
- Rainwater harvesting and revival of traditional and new water storage
systems are crucial for water storage but must be adapted to the more
extreme water events.
- Improved government policies must be developed to support and facilitate
local adaptation strategies and to increase long-term resilience, not just
disaster management.
- Increased efficiency of irrigation and water use is urgently needed - a
new Blue Revolution in Asia could increase water availability for crop
production.
- Livelihood diversification increases resilience to extreme events as
much as income level and should be supported through investments.
- Government policies must support and strengthen social capital and
networks.
Some regional statistics:
- The warming in the Himalayas appears to be much faster than the global
average, for example, 0.6 degrees Centigrade per decade in Nepal compared
with the global average of 0.74 degrees Centigrade over the last 100
years. The rate of change is higher at higher altitudes.
- Glaciers are generally receding in the Hindu-Kush Himalayas, some 40-80%
have been projected to be lost by the end of the century, with the
exception of the Karakoram, where the glaciers have been more stable.
- The proportion of glacial melt in rivers varies from 2-50%, with
mountain snow and ice being critical for much larger shares of the flow in
some rivers.
- Irrigation water from rivers sustains nearly 55% of Asia's cereal
production and around 25% of the world cereal production, feeding over 2.5
billion people in Asia. Another UN report, "The Environmental Food
Crisis", warned that the melting glaciers and snow could jeopardize world
food security and drive prices to unprecedented levels.
- The most serious short-term changes are probably related to the
frequency and magnitude of extreme weather events, such as high intense
rainfall leading to flash floods, landslides, and debris flows, as well as
extreme drought.
- The hydrological role of snow and ice from the mountains is particularly
high for the Tarim, Syr Darya, Amu Darya, Indus, Ganges, Brahmaputra,
Yangtze and Huang He (Yellow) rivers.
- Over 1.3 billion people live directly in watersheds critically dependent
upon glacier melt, snowmelt and water from the Hindu Kush-Himalayas.
- An estimated 516 million people in China, 526 million people in India
and Bangladesh, 178 million people in Pakistan and northern India, and 49
million people in Central Asia, including Xinjiang in China, are thought
to be at risk from water shortages.
- Floods impact several million people every year in the region, and lead
to thousands of casualties.
- The risk of glacial lake outburst floods ('GLOFS'), the sudden bursting
of natural dammed melt lakes at the mouth of glaciers, is increasing as
glaciers continue to retreat; with a potential to destroy lives,
livelihoods, and infrastructure up to 100 kilometers downstream.
