Climate change Human activities vs Earth
evolution

• Are human activities the main cause of climate
  change or can this be considered as a natural
  consequence of the Earth climate evolution?

4
Natural climate variability?
5
Anthropogenic climate change
6
Will man ever be able to be in harmony with the
natural environment?
When ecosystems can provide their natural
services so life is sustainable

• To achieve
• Alternative energy supplies
• Reduction in population
• Advances in scientific understanding
• Change in lifestyle
• Education

• Obstacles
• Cultural and economic objections
• Human mindset
• Trial and error learning
• Political systems

7
The Kyoto Protocol

• First internationally binding agreement
  involving almost all countries
• Ratified 1997, commitment period 2008-2012
• Goal GHG emission reduction min. 5 (1990
  baseline)
• An effective solution?

8
Kyoto and Food/Water

• KP has impact on economic growth and development
• Tension between humanitarian interests
  (food/water supply) and CC mitigation

9
Shortcomings of KP

• Tougher targets needed
• Biggest emitters did not commit to reductions
• Mechanisms cannot replace reduction commitment
• Incentives and enforcement

10
Looking to the future Copenhagen
11
Does CC endanger food supply?

• Integrated approach
• Non-climatic and climatic drivers
• Local ? global approach
• Mitigation and adaptation
• Strengthening and empowering existing
  institutions
• Coordination between actors at each level
  horizontally and vertically

12

• Policy responses
• Reduce trade barriers
• Agro-technology (e.g. GMO, irrigation)
• Efficient and sustainable use of resources
• Raising awareness (communication, education)
