# Emissions from Land Use Change (ELUC) | ||
|
||
Goal: provide decision makers with tools to know how their land-use choices affect CO2 fluxes in the long-term. | ||
|
||
The tools should help decisions makers with their choices: | ||
- For a geographical grid cell, identified by its latitude and longitude, what changes to the land usage can be | ||
made to reduce CO2 emissions? | ||
- What will be the long term CO2 impact of changing the land usage in a particular way? | ||
|
||
## Data | ||
|
||
### ELUC | ||
|
||
BLUE simulations with committed emissions could be used to estimate the long-term CO2 impact. | ||
Committed emissions: all the emissions that are caused by a land-use change event are attributed to the year of the event | ||
BLUE (bookkeeping of land use emissions) is a bookkeeping model that attributes carbon fluxes to land use activities. | ||
See [(BLUE: Bookkeeping of land use emissions)](https://doi.org/10.1002/2014GB004997) for more details. | ||
|
||
The team in charge of the BLUE model performed such simulations with BLUE and generated the file | ||
`BLUE_LUH2-GCB2022_ELUC-committed_gridded_net_1850-2021.nc` available in | ||
[this shared folder](https://syncandshare.lrz.de/getlink/fiAuJz5VFgsEJ1E96mthCT/Data_GCB2022). | ||
|
||
### LUC | ||
|
||
The Land Use Change (LUC) data provided by the LUH2 project [(LUH2: Land Use Harmonization 2)](https://luh.umd.edu/) | ||
|
||
## Modeling | ||
|
||
### Context | ||
|
||
The context is the current usage of the land | ||
|
||
### Actions | ||
|
||
### Outcomes | ||
|
||
1. Emissions from Land Use Change (ELUC): CO2 emissions, in metric ton of carbon per hectare (tC/ha), | ||
resulting from the land use change | ||
2. Percentage of land that was changed | ||
|
