Introduction
  • Flash news in TV, on the Web
  • Catastrophic events like the major floods, heat
    waves and forest fires in Europe, as well as the
    disastrous hurricanes in the USA and draughts in
    Australia

3
Introduction - Cont.
The growing worldwide exposure to natural
catastrophes has become very evident in recent
years
National Geographic
  • Over the last two decades, the world has
    experienced a clear increase in the number, scale
    and economic impact of such events.
  • The scale and frequency of natural catastrophic
    events are likely to increase

4
World under the change
  • Depending on the locality ? consequences are
    different

World under the change
  • Consequences are different
  • ? Increasing global air und sea surface
    temperatures,
  • ? Rising global average sea level,
  • ? Widespread melting of snow and ice,
  • ? Extreme weather events likelihood
  • ? Increase of losses due to extreme weather
    events precipitation and temperature patterns,
  • ? Increased costs of coastal protection and
    land-use relocation
  • ? Damage to coast and coral riffs
  • ? Land degradation and wildfires
  • ? Losses in agriculture (area affected by
    droughts),
  • ? Soil erosion, flash floods, landslides,
    mudslides,
  • ? Heavy precipitation events

STOP ! We know it causes?
6
Basic question ?
  • Question IS NOT TECHNICAL (How to protect the
    Danube basin)
  • ? intelligent and competent people will find the
    solution
  • even ECONMICAL (Who will pay it?)
  • ? priority? we have enough money for military
    experiments and space exploring (in the
    necessity, we will have founds!)
  • The most important is
  • Are we able to change the trend of the recent
    decades?
  • Two strategies ? ADAPTATION
  • ? MITIGATION
  • Question for the policymakers

7
IPCC (says YES)
  • The answer is clear (?)
  • According to the reports of IPCC (UN
    Intergovernmental Panel on Climate Change) namely
    the Fourth Report AR4 published during the year
    2008 the influence of mankind activities namely
    burning of fossil fuel are the main reason of
    climate change.
  • The reaction of politicians was straightforward
    it is necessary to mitigate the climate change by
    reducing emissions of greenhouse gases (GHG
    emissions).

8
GHG Theory
  • The requirement for reduction of emissions of GHG
    seems as a quite reasonable solution of the
    situation climate change and global warming
    problems.
  • However, now some scientists deny such
    straightforward relation between concentrations
    of GHG (namely CO2) and temperature.
  • They claim that in proxy data from the past 650
    000 years at first the temperature starts to
    increase and then! the concentration of CO2!
    (with different time lag 200-800 years)

9
M. Leroux, B. Lombork (No)
  • Marcel Leroux even does a question mark to his
    investigation of temperature increase as a result
    of CO2 increase and concludes Greenhouse effect
    does not control the evolution of temperature
    Such statement if proven would have very
    important impact on mitigation policy!
  • Prof. B. Lomborg in his famous book Cool it
    claim, that reduction of emissions of fossil fuel
    will cost much more then direct adaptation
    actions (like adaptation in water resources
    management and other sectors).
  • He is a perfect statistician and every sentence
    that is written in his book is based on a
    statistical analysis!!!

10
Messages for policymakers
  • Progress requires the policymaker's activity
  • The Open Letter of one hundred of scientists to
    the general secretary Ban Kimon of UN on the
    climatic conference in Bali criticized the way of
    interpretation of the results of many scientists
    by IPCC with preference of one hypothesis of the
    role of GHG in the atmosphere and global warming.
  • The Report of the House of Lords in UK (Selected
    Committee on Economic Affairs The Economics of
    Climate Change) declare, that global warming
    will continue even under the worldwide actions
    (like promised by EU of G8).
  • The work of IPCC is also criticized
    (underestimation of positive effects of climate
    change in results of AR4)

11
Main idea of introduction
  • The problem of climate change and its causes has
    not been definitely solved by the reports of
    IPCC.
  • It is still a scientific problem and the
    political reaction to it should consider this
    fact!
  • technical and economical solutions can succeed!

In such a situation of uncertainty Water
management has mighty tools checked already in
reality scenarios risky analysis
12
Climate change scenarios
  • Predictions of climate change vary from
    relatively slow step-by-step changes of climate
    to revolutionary possibilities with instability
    and wars. (e.g. Schwarz and Randall)
  • IPCC investigated this problem and offered six
    main scenarios of the human society development,
    (IPCC SRES) namely A1B, A1T, A2, B1, and B2.
  • The scenarios are the basis for prediction of the
    GHG concentration (co called post-SRES), derived
    by different climatic models. Using these
    scenarios and climatic models the prediction of
    temperature till 2100 ranges from 1,1C
    temperature increase to 6,4 C increase with a
    majority between 1,8 4,0 C increase.
  • Further analysis is necessary to achieve more
    precise
  • estimation.

13
Stern Report
Despite this situation some scientist like N.
Stern force the politicians to immediately start
actions as he and others recommend applying the
so-called precautionary principle. He claims that
postponing might be very expensive. Other
scientists like B. Lomborg (and president of the
Czech Republic V. Klaus) recommend postponing
adaptation and mitigation actions (expensive
reduction of GHG emissions) as future generations
will be far richer and their technology will be
more developed to deal with the problems of
climate change.
14
Water Policy Implications
  • Can a recommendation for water policy be derived
    under such different attitudes to the problem of
    climate change?
  • YES, IT CAN! (and it will be summarized in the
    conclusion part)

15
Politicians Reaction COPs
  • The majority of politicians agree in their
    proclamations on the necessity to reduce the
    emissions of CO2.
  • The slogan of EU in 2020 20 reduction and in
    2050 - 50 is a clear and ambitious! example.
  • However, in the negotiations of COPs (Conferences
    of UNFCCC) it comes out, that the transition of
    these proclamations into real commitments is a
    very difficult process!

16
Financial Crisis CC
  • Experts fear the financial crisis will discourage
    governments worldwide from turning to taxpayers
    for assistance in climate-change efforts.
  • On the other hand the ecologists claim that the
    "unprecedented" financial crisis (no matter how
    severe) - will be short-lived and should not
    stand in the way of global action on climate
    change!
  • Many economists warn that each percent of
    reduction may result in a very expensive
    reduction of GDP with transfer of production from
    Europe to the third world like China and India.
  • The result for water policy is to stay on the
    ground and do the win-win actions that
    will assist to water management in each situation
    - small changes of climate or big ones.

And now, It is the time for the direct
solution time for Prof.Zdenek Kos and
GEOINGENEERING
17
Risk management and geoengineering
  • Planning of economic development under the risk
    of climate change and its impacts is a typical
    risky situation. Why not to apply the methods of
    risk management to find the most critical parts
    and situations of the economic and environmental
    systems and concentrate on solving of these
    situations.
  • Of course, the solutions require adequate
    technical measures to be at hand in the time of
    the necessity of their application. The proposal
    for such measures exists, and it is not new.
  • Even in 1965 on president of the USA Johnson's
    desk there was a report "Restoring the Quality
    of Our Environment"- that recommended to raise
    the albedo, reflectivity, of the Earth to
    counterbalance the effect of CO2 increase.

18
Albedo change
  • Such a change in albedo could be reached by
    splitting of some material (aluminum powder of
    sulfates) in the upper part of atmosphere
    stratosphere.
  • This method was lately called geoengineering the
    worldwide engineering action to govern the
    climate system.

19
P. Crutzen
  • The modern debate on geoengineering was started
    by Paul Crutzen, winner of the 1995 Nobel Prize
    in chemistry for his ozone hole work.
  • The prestigious journal Climate Change devoted
    an entire issue to the subject. The Journal
    Climatic Change published many articles on this
    topic.
  • The original Crutzens proposal is to pump
    sunlight reflecting sulfur particles into the
    atmosphere. Weve had several experiences with
    the cooling effect of atmospheric sulfur.
  • In 1815, the eruption of Mount Tambora caused the
    year without summer. In 1991, Mount Pinatubo
    spewed forth enough sulfur to cool the Earth
    about one degree for several years. Thats about
    equal to the planetary warming weve experienced
    over the past 100 years.

20
Aluminum powder
  • Other ideas include placing aluminum-powder into
    stratosphere, detuning airplane engines so jets
    fly dirtier and emit more carbon soot (the
    sunscreen proposal), and spraying seawater into
    clouds to increase the albedo effect.
  • All of these proposals would cool the planet
    without any reduction in CO2 emissions.

21
Geoing is fast
  • Proponents dont believe geoengineering will
    solve all the problems.
  • Rather, it is a valuable method of risk
    management when all other methods fail to stop
    immediately for instance the rapid increase in
    the sea level. It buys time while we develop and
    deploy alternative fuels and figure out
    acceptable policies to reduce or stabilize
    atmospheric CO2.
  • Effect of geoengineering is counted in months
    rather that decades.

22
Geoing who operates?
  • Geoengineering will receive ever more attention
    from scientists and policy makers, as the hidden
    costs of schemes like the Kyoto Protocol become
    obvious.
  • These costs are probably too high for politicians
    to bear, namely facing the economical crisis.
  • Of course, we can geoengineer the climate - but
    this raises important questions. Who sets the
    thermostat?
  • Do residents of small islands turn the dial,
    since a future rise in sea level could submerge
    their homes? Or do the Russians in Siberia?
  • They might prefer some moderate warming to
    increase agriculture in Siberia and provide
    ice-free ports.

23
Geoing long way to realize
  • Geoengineering approach will be probably
    successful, popular, and cheap.
  • However, what will the situation if the
    implications if environmentalists, rejecting
    technological fixes will fight this?
  • They will risk condemnation for opposing
    pragmatic solutions to climate change.
  • Dealing responsibly with our changing climate
    requires a portfolio of strategies, probably
    including geoengineering.
  • However, it will be a long way from the
    recommendation of scientists like Crutzen to the
    portfolio of politicians.

24
Impact of climate change on water policy
  • The two basic methods to deal with the impacts of
    climate change we already mentioned - mitigation
    and adaptation.
  • While mitigation is in general out of scope of
    water policy (excepting water power plant
    preference with no emissions of GHG to thermal
    power plants) the main method in water policy is
    adaptation.
  • However the question might be adaptation to which
    station of the climate system moderate or severe
    change of climate. The answer is relatively easy
    adaptation to unexpected situations (IIASA 1980
    Expect unexpected).
  • In water policy it is a very rare the case of an
    over-designed project. Water policy projects are
    typically multi-objective and if one objective is
    not fully justified at this moment the other can
    stand in his place.
  • The resulting requirement is plan and
    construct robust systems.

25
Adaptation and mitigation in Water Policy in
the CR
  • Adaptation and mitigation in Water Policy in
    the Czech Republic
  • For solving the climate change problems, we have
    many tools related with water management and
    water policy.
  • In general, two basic ways of the climatic change
    problem-solving are known. Mitigation (involves
    actions to reduce greenhouse gas emissions and to
    enhance sinks aimed at reducing the extent of
    global warming - Aquatic plants and bank
    vegetation support).
  • The adaptive arrangements are taken for minimize
    the negative consequences of CC.
  • For water management in the Czech Republic we
    could mention such as microclimate benefits,
    water (drinking, irrigation, industry) supply
    safety, ... Not only the technical arrangements
    in the catchments, but also the educational
    training, operation plans and legislation support
    are necessary.

26
Water Policy and Adaptive IWRM
  • Water Policy and Adaptive Integrated Water
    Resources Management (IWRM)
  • Integrated water resources management (IWRM) was
    defined as a process, which promotes the
    coordinated development and management of water,
    land and related resources in order to maximize
    the resultant economic and social welfare in an
    equitable manner without compromising the
    sustainability of vital ecosystems.
  • This resulted in the human dimension and
    stakeholder involvement being identified as an
    integral part of water management.
  • The adaptive approach is based on the hypothesis
    that IWRM cannot be realized unless current water
    management regimes undergo a transition towards
    more adaptive integrated water management
    (AIWRM).

27
AIWRM
  • AIWRM can more generally be defined as a
    systematic process for continually improving
    management policies and practices by learning
    from the outcomes of implemented management
    strategies.
  • New water policy focuses on the transition of
    current water management regimes to adaptive
    water management where adaptive management is
    aimed at integrated system design.

28
Conclusion
  • Adaptation in water policy is an integral and
    preferable method of adaptive integrated water
    resource management (AIWRM).
  • Very important claim of water policy using
    adaptive integrated water resource management is
    Plan and design robust systems.
  • The starting point in water policy should be the
    accomplishment of the win-win and no regret
    actions, i.e. actions that need be realized in al
    cases regardless of climate change.
  • The problem of inadequate adaptation capacity can
    be solved by the modern technology like
    geoengineering.
