Outline
• INCAS Overview
• Current Status
• General Approach
• Spatial Modelling
• Emissions Modelling
• Improvement Plan
What is INCAS?
A system for accounting GHG emissions and removals to support MRV requirements for the land sector in Indonesia, including REDD+ activities
MRV and policy/decision support tool
Basis for GHG inventories & international reporting
Track progress towards emissions reduction targets
Support sustainable land use planning, sustainable management of forests, watershed management etc.
INCAS Key Features
Systematic and nationally consistent GHG accounting system for the land sector
TACCC principles
Flexible approach to support multiple reporting requirements
Tier 3 ‘model-based’ MRV system
Use the best available data
Continuous improvement
Robust and repeatable
Current Status
Category Coverage (currrent version)
Land • All natural forests, timber plantations, and estate crops on deforested lands;
• All peat lands
Activity • Forest land (deforestation, forest degradation, sustainable management of
forest, enhancement of forest carbon stocks)
• Peat land (fire and biological oxidation)
Management/
event type
• Clearing (conversion of forest to other land uses, conversion of primary forest
to secondary forest, conversion of secondary forest to timber plantations),
• Logging (conventional logging, reduced impact logging),
• Fires (moderate/intense fires),
• Planting (by species)
Carbon Pool Aboveground biomass; belowground biomass;litter; woody debris; soil
Source of GHG CO2-e, CH4, N2O, CO, NOx
Period of actual emissions Annual (2001, 2002, 2003, 2004, 2005,... 2012)
Extent National, subnational (34 Provinces)
• Endorsed by the Minister as a national platform for GHG accounting for the land sector
• Starting with forest and peat lands, will be expanded to other land uses
• Under R&D phase, will be operationalized

Forest Emissions and Removals
Inputs:• Location of forest
disturbance
• Initial conditions (forest biomass & carbon)
• Forest growth and turnover rates
• Forest management events
Output:
• Estimate of carbon flows between different carbon pools and ultimately emissions and removals (Tier 3).

Improvement plan
Continuous improvement is a fundamental principle of the INCAS approach
The system framework is flexible to incorporate the improvements without significant changes
INCAS Roadmap - incorporating all land sector activities and further reducing uncertainties in GHG emissions and removal estimates in future national inventories
• Incorporating more data sets
• Increasing the length of the time series of forest cover change
• Improving fire mapping
