Recent floods and rain in N Karnataka
Recent floods and rain in N Karnataka
• Altered rainfall pattern
– Sept-Oct 2009
– Usual rainfall
• In the region – 35 mm; Actual rainfall: 251mm
• In Bijapur District – 34 mm vs 334 mm
• Issues of Reservoir management
• Predictability, Preparedness
• Weakness of the infrastructure to cope with such
situations
• Associated challenges – HEALTH, SANITATION
Changing disease patterns….
• The epidemic of Dengue and
chickungunya
Indicates
• Altered rain patterns
• Poor sanitation – cesspools
etc
• Altered vector patterns
• To be viewed in the socio
cultural setting of the
community
• Groundwater table in HDKote
– Water – so near, yet so deep!!
• Impact of tsunami
• The struggles in Bangladesh and Nepal……
Some basic truths….
• Climate change is happening…
• Water - the main mechanism of impact of climate
change on people as well as eco system..
• Water and thereby sanitation are the main
mechanisms for impacting human health..
• Achieving wat-san MDGs are key to achieving
other MDGs, but currently, sanitation is way off
track…..
• Costs of impacts enormous….
The policies and
practices in water
management can have
short and long term
effects
on
climate
change, and therefore
potentially magnify all
the other deleterious
effects.
•Climate Change
exerts its impacts
mainly thro water.
•Other impacts
are mediated thro
the primary
impact on water
Food, energy, livelihood, environment….
•An already-stressed, finite resource is further jeopardized by the direct
and indirect impacts of climate change.
•Optimal management of this resource is key to achieving all the MDGs –
indeed to the very health of the ecosystem
Climate change impact on water cycle
• Amount, intensity and distribution of precipitation
• Alterations in run-offs
– Ground water levels
– Coastal zones
• Tsunami; Erosion; salinity
– Water quality
• Concentration effect; floods-droughts leading to contamination
– Water Storage-management – Reservoirs
• Silt
– River basins
• Food security
Serious Impacts on water for drinking and domestic
consumption

Climate change impact on water cycle
Climate Change Impacts on sanitation and
Health
• Diseases caused as Direct impacts
– Heat strokes etc
• Diseases due to Climate-induced impacts on
environment (Floods-drought etc)
– Diarrhoeal diseases; vector borne diseases;
Starvation-malnutrition; allergic disorders
• Health consequences due to economic, social
and other changes
– Migration; Nutrition; mental illnesses
The key areas of concern….
• ACCESS - Serious crisis of availability of safe and
adequate drinking water
• HEALTH -Public Health considerations to get
adequate priority
• EQUITY – in the face competing demands to
ensure inclusivity and proper prioritization –
sector (drinking, agri, industrial etc), geographic,
social.
• COMMUNITY-CENTRICITY - community-centric
planning rather than Technology- or funds-driven
planning
The key areas of concern….
ACCESS
HEALTH
EQUITY
COMMUNITY
CENTRICITY
Adaptation is not merely infrastructural, but is
a complex interplay of many institutional
mechanisms, including policy, finance and
governance.
Adopting the right Adaptation
approach…

Approaches to drinking water
access……
• Diversification of water sources
– Avoiding Single source dependence
– Rain water harvesting
• Resilient, sustainable water supply systems
• Surface water management
• Reservoir management
– Requirements vs flood run offs; safety issues;
• Ensuring adequate groundwater recharge
– High intensity precipitation with rapid evaporation
rates
Approaches to reduce health impacts
Adaptation option
Inter-agency cooperation
Reduction of social vulnerability
Public education
Improvements of public health
infrastructure
Support for infectious disease control
Monitoring and surveillance of
environmental, biological and health
status
Urban design (including transport
systems)
Housing, sanitation, water quality

Policy-planning guidelines thru
UNFCCC
• Convergence at the level of planning –
mainstreaming of ‘adaptation’ into current schemes,
of development initiatives in general, and water
management in particular
• To Ensure Water Access
– IWRM approach
– Ensuring priority for drinking water over other competing
water needs
– Priority for water in adaptation interventions
• Focus on Public Health in Adaptation Plans
– 2009 preparatory documents – only 4 out of 49 speak of
health as a concern (McMicheal et al,www.lancet.com)
Policy-planning guidelines thru
UNFCCC
• Enhancing accountability thro support to participatory
and democratic processes
• Support for resolution of contentious issues like trans
boundary water
• Regional balance – equitable distribution of funds,
functions and functionaries
• Special focus on vulnerable groups
• Balanced move towards ‘privatisation’ and pricing,
with a recognition of Human Rights
– Willingness to pay vs Ability to pay.
• Guidelines for habitations – urbanisation/
rehabilitation/ migration
Policy-planning guidelines thro
UNFCCC
• Support for Community involvement, awareness;
– The River users groups in Tamil Nadu
– Decentralisation of planning and decision making.
• Promotion of, and building on, Relevant traditional
practices
– The lakes in South India; the open well system
• Economic development to be ‘clean’ and eco-sensitive
– Avoiding ‘developmental disasters ‘– resulting in large
scale displacement
• Mitigation and Adaptation mechanisms themselves to
be safe and holistic
Climate proofing
• Mandatory Environmental Impact Assessment to
determine the impact of the project on the environment
• Need for reverse impact assessment – assess the impact of
the environment on the project
– Defining existing conditions/components;
– Projecting and estimating likely future changes for each
component;
– Recording extent of interactions and identifying the variabilities
– Determining critical thresholds when risk of a climate change
impact becomes dangerous; and
– Determining value of these impacts economically as financial
loss and biologically.
• The ifs and buts of the River Linking Project…..
Costs of adaptation
Agency
UNFCCC
Overall adaptation cost
projected
49 – 171 b USD /y by 2030
Oxfam
>50 b USD /y
World Bank
9-41 b USD /y
UNDP
86-109 b USD /y by 2015
•Significant variations in the projections.
•Agriculture, water, health, ecosytems, coastal areas,
infrastructure
•Projections have been analysed and critiqued .
Martin Parry et al; www.iied.org/pubs/pdfs/11501IIED.pdf
Cost of adaptation – water sector
• Expenses to be considered
– Cost of explicit measures
– Transactional costs
– Costs of residual impacts
• Estimate – 9-11b $ per year by 2030
• Likely to be higher due to:
– Does not include other measures like managing flood
risk, water quality etc
– Does not include the costs of residual impacts
– Represents only the additional investment
Cost of adaptation – Health sector
• Expenses to be considered
– Cost of improving/modifying health protection systems –
eg surveillance, training
– Cost of modifications of hospitals, staff safety etc
– Disease burden prevention costs
– Research
– Meeting newer standards of pollution control
• Estimated to be 5-12 b $
• Likely to be higher due to:
– Disease burden not fully considered; decline in rates
assumed
– Cost escalations over time
– Residual impacts in the form of failure of prevention
In conclusion
• Climate change impacts are inevitable,
and hence the imperative to ‘adapt’
• Water, the main mechanism of impact,
and hence of adaptation as well
• Access, Health, Equity and Communitycentricity – the main challenges to be
addressed
Climate Change adaptation without focus on
water, is a watered down effort.
Focus on Water for Climate Change
Adaptation
NOW,
nurtures the Change in all sectors for
TOMORROW!
