2Introduction
- 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
3Introduction - 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
4World under the change
- Depending on the locality ? consequences are
different
GEOPHYSICAL FLUID DYNAMICS LAB. NOAA
5World 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?
6Basic 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
7IPCC (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).
8GHG 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)
9M. 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!!!
10Messages 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)
11Main 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
12Climate 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.
13Stern 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.
14Water 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)
15Politicians 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!
16Financial 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
17Risk 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.
18Albedo 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.
19P. 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.
20Aluminum 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.
21Geoing 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.
22Geoing 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.
23Geoing 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.
24Impact 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.
25Adaptation 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.
26Water 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).
27AIWRM
- 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.
28Conclusion
- 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.
