STRATEGICC: State and Transition Integrated Economic-Environmental Accounting

A python package implementation of State-and-Transition Simulation Model (STSM) framework laid by Daniel et al (2016) (https://doi.org/10.1111/2041-210X.12597), integrated with the System of Economic-Environmental Accounting - Ecosystem Accounting (SEEA-EA) by United Nations (https://seea.un.org/ecosystem-accounting).

Usage

install the package

!pip install git+https://github.com/Shlhnj/strategicc.git

Diagnose Configuration

from strategicc import STSMEngine

engine = STSMEngine.from_config()
engine.load()
engine.diagnostic()

Run Engine

engine.run()

Show Summary Plot

from strategicc import outputs

summary_dir = engine.out_dir / "summary"

print("Building summary tables...")
area_df, trans_df = outputs.build_summary_tables(engine.iter_dirs, summary_dir)

print("Plotting area envelope...")
outputs.plot_area_envelope(area_df, engine.classes, summary_dir)

print("Plotting transition envelope...")
outputs.plot_transition_envelope(trans_df, summary_dir)

Show plots inline
from IPython.display import Image, display
display(Image(str(summary_dir / "area_envelope.png")))
display(Image(str(summary_dir / "transition_envelope.png")))
