1.5 What strategies can be used to address climate change?A) At an international levelB) By governmental actionC) By pressure groups and individuals.
Adaptation is when strategies are used where people cope with climate change. People change their way of life. This is not a solution but a reaction.
Mitigation is when a strategy is in place to reduce the effects of climate change. This can be done at various scales from local to national to global mitigation.
Adaptation is directly linked to development.
• Wealthy countries have the resources to adapt. Poor countries lack this ability.
To be able to adapt the following would need to be
done:• Reduce global poverty• Increase access to resources• Improve education• Improve health and population
stability• Improve infrastructure
Adaptation or Mitigation?
• Adjustment in natural or human systems to a new or changing environment.
• An anthropogenic intervention to reduce the sources or enhance the sinks of greenhouse gases.
• Sea defences.• Renewable energy.• Move from coastal areas threatened
by sea level rise.• Planting trees.• Promoting use of public transport.• International treaties to lower
greenhouse gas emissions.• Develop ecotourism.
Questions:1. What is the difference between
adaptation and mitigation?2. What is an example of a mitigation
strategy?3. What is an example of an
adaptation strategy?4. Which type of strategy will have the
biggest reduction in greenhouse gases?

Carbon capture technology
Carbon neutraldevelopment
1. Prevent development
on flood plains/ Coasts.
2.Build fire breaks around urban areas
1. Drought tolerant crops
2. Water harvesting
3. Use of grey water
1. Orbiting solar shields
2. High yield variety
1. Reduce resource Consumption
2.Increased recycling
3. Locally sourced food products
4. Alternative transport
1. Large scale carbon capture technology applied to power
stations and
industries.
1.Afforestation
2. Renewable energy supplies
3.International
agreements.

Fire breaks in Australia
• A gap in vegetation (barrier)• Reduce the threat of bush fires.• Melbourne is already surrounded by
more than 500km of fire breaks.• This was extended in 2011.• Focus on areas identified as high
risk.
Green revolution
• 1940-1970• HYV of cereal grains, Irrigation,
modernisation and management.• Saved India from mass famine in
1961• 1960- rice yield 2 tons per hectare,
by 1990- 6 tons per hectare
Use of greywater
• Used water (laundry, bathwater etc)• Recycled on site• Environment agency promotes it’s
use• We all produce approx. 120 litres of
greywater a day, which could be redued to 30 litres.
Alternative transport
• London schemes• Congestion charges- Introduced in 2003-
busy areas- ~ £10 per day (Fines for not paying)
• Incentives- electric cars
• Bikes- London cycle hire- available 24/7• 15,000 docking stations around London.• Cover 65km2
Carbon capture technology
• Aim- to trap greenhouse gases after burning fossil fuels.
