Project Drawdown Land Utilities for Solutions. There are three kinds of land divisions recognized within Project Drawdown:

• Regions: these are the geo-political regions such as OECD90 and Latin America
• Thermal-Moisture Regimes, aka TMR: designations such as Boreal-Humid, etc.
• AEZs: this is a custom PD analysis of land areas combining land type, soil quality and slope steepness

Geographical analysis to create a cross-correlation between these three dimensions has been done, and the original work is available at [https://github.com/ProjectDrawdown/spatial-aez].

Land-type solutions are usually only applicable within certain TMRs. Within a given TMR, multiple land solutions might compete for the same land. PD has established a priority between multiple solutions within AEZ types, and from that prioritization, determined a maximum available land allocation for each solution within each political region/TMR area. This is known as the "Total Land Allocation" or TLA, and it works analagously to the "Total Available Market" in other solutions.

The TLA is established by the integration process in integrationsez_land_integration.py. The integration process is run periodically to create updated TLAs which are stored in the data directory. Individuals may run the integration process themselves to replicate that work, or experiment with alternatives.

Currently PD models land types as unchanging over time. Future research may include forecasts of land changes over time, e.g. due to climate change modeling.

This module contains the classes for solution-specific land allocations. See the module world_land for global land data.
