Impact of Rising Sea Levels on Urban Development
- Huge demand for waterfront and near waterfront
property - 36 of entire U.S. property values are on the
coastline - Between 1980 and 2003
- 33 million moved to a coastal county
- Over 7 million in Florida
- 2.5 million in Texas
- Disappearing coastlines due to erosion and sea
level rise

7 Impact of Rising Sea Levels on Urban Development
- SEA LEVEL RISE COULD LEAD TO
- flooding of low-lying property
- loss of coastal wetlands
- erosion of beaches
- saltwater contamination of drinking water
- decreased longevity of low-lying roads,
causeways, and bridges - increase the vulnerability to storms and
associated flooding
POSSIBLE ADAPTATIONS TO SEE LEVEL RISE -
(Planned) Retreat all natural system effects
are allowed to occur and human impacts are
minimized by pulling back from the coast -
Accommodation all natural system effects are
allowed to occur and human impacts are minimized
by adjusting human use of the coastal zone -
Protection natural system effects are
controlled by soft or hard engineering, reducing
human impacts in the zone.

9 Climate Change- Consequences for Europe
- The global mean temperature should rise about 2-
3 C by 2050. - The Arctic Ocean should be ice-free by 2100
- This could imply extinction of 10 of all
terrestrial species - Sea level would probably rise about 0.20 m or
more - Flooding of areas in the Netherlands and North
Germany may be possible - Farming conditions should improve in northern
Europe - Flooding of rivers and heavy rains in central
Europe will become common events - Rainfall decrease in southern Europe (Spain,
Italy and Greece) - This should cause problems for farming and
drinking water supply - Could also imply more frequent forest fires and
decline of vegetation - Could also increase cases of verminosis, malaria,
borreliosis and meningoencefalitis - Tourism industry decreases in mountainous regions
(especially 1200- 1500 m) - Extreme weather conditions would be more frequent
- Climate change in Africa and Middle East could
bring more immigrants to Europe

10 Climate Change- Consequences for Europe
- Proposed adaptation measures
- In the next decades, plans for dam-building are
available . But more research is needed for
dam-raising after 2050. - Larger artificial flooding areas along the rivers
would be necessary - Improvements in irrigation concepts and farming
should be developed - Water and sewage management should be improved
and more reservoirs built - Alternatives to winter sports should be devised
- Air-conditioning in residential, commercial and
industrial buildings will require more energy - More research is needed to understand immigration
causes
- Proposed mitigation programs
- Saving forest areas
- Artificial storage of CO2
- Energy production with reduced or without GHG
- wind power,
- solar-energy,
- geothermal energy
- nuclear energy

yields - Reductions in rainfall 20 May impact pastures
in semi-arid regions - Increases in rainfall Increase productive
rangelands and disruption to fisheries in

should lose considerable agricultural resources - Water
- Global mean temperature increases gt 1C
- Increases in runoff around 30 in central

water stress by 2050s - Water stress likely to increase from 47 in 2000

Adaptation - Reduce vulnerability of poor populations in
sub-Saharan Africa to climate change by
mobilizing scientists and all the other important
players in political decision-making. - Strengthen the Capacity to Adapt to
ClimateChange in Rural Benin - Support surveillance committees in 35
communesand foster farmer experimentation in two
field-schools in each commune . - Strengthening the Capacity of Smallholder

18The PROALCOOL Program
- The PROALCOOL program was created by the
Federal Government on 14 November 1975. - This was done after the development at ITA
(Aeronautics Institute of Technology), at the
beginning of the same year, of the first motor
using ethanol as fuel. - At the time, its aim was the reduction of oil
imports. Improvement of urban air quality and
decrease of GHG emissions were pointed out as no
more than a bonus. - Besides the ethanol motors, it was decided to
add 20 ethanol to gasoline. This addition was
decided after agreement with the automakers to
adapt motors

Paulo, São Paulo, Brazil, 38ª WFS General
Assembly, Erice
19The PROALCOOL Program
- After the program implementation the improvement
of air quality was perceived by the urban public
not as a bonus but as the best part of it. - During the 1970s sugar prices were falling on the
international market and oil prices were rising.
This greatly contributed to the programs initial
success. - In the 1990s oil prices were falling and sugar
prices were rising, thus the industry preferred
to make sugar instead of ethanol, and an ethanol
shortage occurred. - Government and Petrobras tried to reduce the
percentage of the addition of ethanol to gasoline
to avoid ethanol importation.

Paulo, São Paulo, Brazil, 38ª WFS General
Assembly, Erice
20The PROALCOOL Program
- The population of big cities public, like São
Paulo, Rio de Janeiro and Belo Horizonte,
protested, and the percentage was maintained at
this moment the PROALCOOL could be understood
more as a program to improve air quality and less
to reduce oil imports. - The consequence of this situation was the
development of flex motors, allowing the consumer
decide what is better for him/her. - As oil prices increased again Brazilian deep
offshore oil wells became economically feasible,
and oil imports is no longer a concern. - But now PROALCOOL is already established as a
GHG reduction program, with more than a million
rural jobs besides the industrial ones.

22Conclusions
- WITH CURRENT LEVELS OF GHG EMISSIONS, DEVELOPMENT
IS NOT SUSTAINABLE. - THESE EMISSIONS AND THEIR STEADY INCREASE ARE OUR
RESPONSIBILITY. - ALTHOUGH EVERYBODY WANTS TO FOLLOW DEVELOPING,
NOBODY LIKES TO BREATHE POLLUTED AIR AND MOST
PEOPLE ARE DEMANDING ABOUT CLEAN AIR,
PARTICULARLY IN BIG CITIES, WHERE MOST PEOPLE
WILL LIVE IN THE MIDDLE OF THE 21ST CENTURY. - MANY GOVERNMENTS DONT SHOW MUCH INTEREST IN
PROGRAMS FOR THE REDUCTION OF GHG EMISSIONS AND
SEEM TO PREFER ADAPTATION MEASURES. - HOWEVER, ADAPTATION MEASURES HAVE A COST AND
OFTEN A VERY HIGH COST AND IN MANY CASES ARE MORE
SURVIVAL DEVICES THAN SOLUTIONS. - IT IS VITAL TO SHOW TO DECISION MAKERS THAT GHG
REDUCTION PROGRAMS COULD PROVIDE GOOD BUSINESS
OPPORTUNITIES AND ARE NOT CHARITY CAMPAIGNS. - MORE RESEARCH IS NEEDED, WHICH IMPLIES MORE
RESOURCES FOR INVESTIGATION ON CONSEQUENCES OF
GHG EMISSIONS COUNTERMEASURES ON DEVELOPMENT.
