of Colombia in Copenhagen
September 2009 Colombia were going to COP15
with a figure of 100,000Ha/year deforestation
Terrai analysis identified MINIMUM
180,000Ha/year, most likely 250300,000Ha/year
Discussions underway for to become a 1st tier

Global Poverty Maps
Compile all the different poverty maps
Merge them together into a single developing
country data set
Make the adjustments from national poverty lines to$1.25 a day and two dollar a day poverty lines
Make the adjustment to a standard 2005 date
Use the headcount ratio (percent population that ispoor) with global population maps to calculate the
number of poor

Downscaled climate change data
http://gisweb.ciat.cgiar.org/gcmpage
Assume geographies of changes in climates don't vary too much atregional scales and relationships between different variables willremain the same in the future
Empirical downscaling approach instead of re-modelling the climate
patterns using an RCM (Regional Climate Model) Calculation of anomalies (if they're not provided directly by IPCC) by
simply subtracting each variable's future values from the baseline(both provided by IPCC)
Interpolation of anomalies to a 30 arc-seconds resolution (approx.1km)
Addition of the interpolated anomalies to the current distribution ofclimates in WorldClim, for temperature we make an absolute sum, butfor precipitation (as there are differences between the GCM baselineand our WorldClim baseline), we use the relative difference

Site specific agriculture
The hypothesis
If it were possible to compile the information on what the
farmer did and characterize the conditions of a largenumber of these experiments it would be possible to
deduce optimum practices for specific conditions

Site specific agriculture
The Concept
Production systems are highly heterogeneous
We need massive amounts of data to understand them, inorder to act and provide recommendations
Every farm is essentially an experimental station
Every crop cycle, management practice is an event (trial, n)
Farmers learn and adapt from an n+ 1 + 1 ..
Learning from collective knowledge far more powerful (n of1,000s)
But, all trials go uncompiled we learn, but not enough
