BioLand-US
BioLand-US tests how much U.S. land allocated to perennial biomass can be supported by compatible agricultural land and voluntary farmer contracts.
The question
Energy-crop models can say where perennial biomass could be grown in the United States. They cannot say whether farmers will sign up. BioLand-US sits between those two things and asks a practical implementation question:
When a techno-economic model allocates land to perennial biomass, how much of that prospective allocation can also be supported by compatible agricultural land and voluntary contractual participation?
The model does not replace or re-optimise the upstream resource allocation. It adds an explicit implementation layer.
Scientific logic
The framework keeps four quantities distinct:
This makes it possible to distinguish technical allocation from land compatibility and actual access through voluntary contracts.
Evidence
The model combines:
- POLYSYS biomass allocation from the 2023 Billion-Ton analysis;
- 2022 U.S. Census of Agriculture land data;
- county cash-rent context;
- experimental evidence on landholder contract participation; and
- county-level spatial matching.
Reproducibility
The public repository contains the code, frozen non-disclosive behavioural parameters, data-access documentation, verification scripts and manuscript-facing outputs while respecting restrictions on respondent-level records.
