ICSU “Grand challenges”

Develop, enhance and integrate the observation systems needed to manage global and regional environmental change.

Improve the usefulness of forecasts of future environmental conditions and their consequences for people.

Determine what institutional, economic and behavioural changes can enable effective steps toward global sustainability.

ICSU “Grand challenges”: a bit of ancient wisdom

Be careful what you wish for….

The challenge: reducing deforestation

Impact of land change in Brazil’s emissions

Medium-resolution (5-50 m) earth observation satellites data are global public goods

Earth observation satellites are essential for measuring land change

T2 – Loss of smaller trees

How does deforestation happen?T1 – Selective logging

T3 – Loss >50% of forest T4 – Loss >90% of forest

“By 2020, Brazil will reduce deforestation by 80% relative to 2005.” (pres. Lula in Copenhagen COP-15)

Market impact of deforestation reduction in Brazil

EU-15 reduction 2005-202020% of 1990 levels

Avoided def Brazil 2005-2020

From 2005 to 2020, avoided deforestation by Brazil would be 2/3 of the total proposed EU-15 cuts

The Brazilian Amazon has different institutional arrangements that influence the spatial and temporal patterns of deforestation.

SÃO FÉLIX DO XINGU - 2006

Full and open access to space-based information is indispensable for global

sustainable development

“A few satellites can cover the entire globe, but there needs to be a system in place to ensure their images are readily available to everyone who needs them. Brazil has set an important precedent by making its Earth-observation data available, and the rest of the world should follow suit.”

Environmental issues are best handled with participation of all citizens.

Each individual shall have appropriate access to information concerning the

environment.

RIO-92 Declaration – principle #10

RIO + 20: bulding on principles from RIO-92

We need a new convention on the public availability of environmental information
