Climate Change
  • What is Ocean NourishmentTM
  • Carbon credits CER GHG credits carbon
    dioxide credits
  • How can Ocean Nourishment help Morocco

Climate Change
  • Climate change has been occurring!
  • Noahs flood brought social change

6
Climate
  • Rapid climate change is undesirable!
  • GHG influences climate
  • We want to manage climate.

GHG Intensity

11
Efficiency
  • Increasing the efficiency will not solve the GHG
    problem
  • A change from 35 to 50 in 20 years would be
    required

GHG Sinks
  • Sinks will be needed
  • Geological sequestration capture costs
  • Biological sequestration

Biological Sink
  • Benefits of Ocean Nourishment
  • Low cost
  • Permanent sequestration
  • Positive environmental impact

Carbon Credits
The concept Nourish the ocean and sell carbon
credits Produce more fish in poor countries This
reduces malnutrition improves, education,
reduces family size Stabilises population before
the ocean capacity is exhausted

Carbon Credits
The cost of carbon dioxide credits US5 US15
per tonne of CO2 Capital costs US
300million Return on investment 30 pa See

Environment

24
Carbon trading
  • Sinks allowed under UNFCCC
  • Parties to .. enhance sinks .. marine ecosystems
  • Kyoto protocol allows trading
  • AIJ (UNFCCC article 4.2)
  • CDM (developing and developed)

OceanOcean Nourishment Experiment
26
Lawrence Livermore National Laboratory, USA

Their numerical model that solves the equation of
fluid mechanics and has a climatological
atmosphere. The model takes one day to advance 50
years and was run up to the equilibrium with the
carbon dioxide level during the pre industrial
period. The nutrients takes of order 30 days to
be spread from the surface layer of the ocean.
Enhanced photosynthetic production and export of
organic carbon occur

27
Comparison of Primary Production
  • Measured Chlorophyll (primary production)
  • Model New Primary Production

28
Numerical Experiment
  • To inject reactive nitrogen to the photic zone at
    the rate of 1,000 tonnes/day for 100 years.

Changed Ocean Productivity
Continuos injection of nitrogen at 33N, 10W after
one year

Changed Ocean Productivity
Continuos injection of nitrogen at 33N, 10W after
500 years

  • Conclusions
  • Greenhouse Gas is of concern to the public
  • Ocean nourishment could play a major role.
  • LIFD countries could benefit
  • There is a business opportunity

32
Conclusion
  • Morocco can benefit from more fish
  • Ocean Nourishment is a promising concept for
    Morocco to support its sustainable development
  • Carbon Credits would pay for this scheme
  • Ocean General Circulation Model with Ocean
    Biological Model have allowed the long-term
    impacts of an Moroccan Ocean Nourishment site to
    be assessed.
