Renewable Energy Projects
Cut down use of fossil fuels
Small scale projects – solar panel, turbines
Bio fuels
More expensive than fossil fuels

Tree Planting
Acts as carbon sink
Benefits not felt for at least 10 years
Energy Efficient
Most effective way
Remodel factories – optimum use of energy
Greener power stations
Green transport – hybrid technology
Rising temps
More droughts
Melting glaciers

Water stress experienced by 40% of population

Applied at all scales
Allow developed countries to pay for greenhouse gas by cutting projects in return for carbon credits World Conference on Disaster Reduction
Hyogo Framework
Community work
Tackling the Challenge
Using technology, soil conservation schemes
Ecosystems very sensitive.
High vulnerability.
Limited adaptive capacity in LEDCs
Longer growing season north
Extreme weather affects crops
Farmland taken up by plants for biofuels
Climate change = more famine in Africa, S.America, Asia
Rapid changes mean people don’t have time to adapt EG Amazon Water Shortages
Economic shortage of water.
Needed for people as well as crops/animals

Food Insecurity
The Challenge
Challenge of Global Hazards for the Future

More impacts – more food insecurity
Conflicts over water crisis
More vulnerable people plunged into poverty
Environmental refugees

More uncertainty – more extreme weather with more uncertainty. Rising temperatures and changing precipitation patterns. Increase in number of storms.

Worsening greenhouse effect – rising sea levels

Increase evaporation – more water vapour
More ice sheet and glacier melts

Higher temperatures – more hazardous world.
Impacts on food and water supplies

Opposed global warming/ climate change till 2002
Promoting energy efficient transport
More energy from nuclear, renewable and bio fuels
Massive polluters
Electricity is the worst

Emissions Reduction Targets
EU 8%
USA 6%

Lifestyle/Consumption choices
Needs to effective on all levels:
Government policies and taxes
Local government strategies; recycling, transport.
Mitigation Strategies
* Setting targets to reduce CO2 emissions
* Green strategies

Coping with Climate Change

Low elevation – height = sea level
Rising sea levels
Reduce supplies of food.
Fresh drinking water spoiled

70% consists of floodplains

Limited resources
Geographical remoteness
Degradation of natural...
