DESCRIPTION
Credible baseline setting and accurate and transparent Measurement, Reporting and Verification (MRV) of results are key conditions for successful REDD+ projects. In this presentation, Gabriel Carrero from IDESAM explains the process of regional spatial and non-spatial modeling for determining a baseline in the Surui Forest Carbon Project. Gabriel Carrero gave this presentation on 8 March 2012 at a workshop organised by CIFOR, ‘Measurement, Reporting and Verification in Latin American REDD+ Projects’, held in Petropolis, Brazil. The workshop aimed to explore important advances, challenges, pitfalls, and innovations in REDD+ methods — thereby moving towards overcoming barriers to meeting MRV requirements at REDD+ project sites in two of the Amazon’s most important REDD+ candidate countries, Peru and Brazil. For further information about the workshop, please contact Shijo Joseph via s.joseph (at) cgiar.org

Baseline Approaches
• Projecting historical average X modeling rates
• Regional modeling– Need local understand, identifying agents, drivers
and underlying causes

– Control over the Territory– Logging agreements– Lease pastures and
sharecropping systems
Baseline Scenario - Agents
– Cash income from external actors (logging, sharecropping and pasture leasing)
– Population growth– Increased labor available
Baseline Scenario - Drivers
