Planetary Boundary Status based on LPJmL simulations

R package boundaries, version 1.2.0

Purpose and Functionality

A systematic approach to quantify the status of the terrestrial planetary boundaries based on the Dynamic Global Vegetation Model (DGVM) Lund-Potsdam-Jena managed Land (LPJmL) hosted at the Potsdam Institute for Climate Impact Research (PIK). The supported planetary boundaries are "biosphere integrity", "land-system change", "bluewater", "greenwater" and "nitrogen flows".

Overview

🌎🌡 Terrestrial Planetary Boundary Status

calc_status() calculate the status of the boundaries based on 🌱 LPJmL Simulations depending on ...

1. 🎛 Scenario configuration
2. 🌐 Spatial scale: global, sub-global, grid
3. 🕚 Time span and resolution
4. 📑 Methodological approach

and returns the status of each underlying control variable.

🎨 Status Visualization

plot_status() visualize the 🌡 status of the 🌎 boundaries based on the calculated control variables either as a 🗺 map or a 📈 time series plot.

Installation

For installation of the most recent package version an additional repository has to be added in R:

options(repos = c(CRAN = "@CRAN@", pik = "https://rse.pik-potsdam.de/r/packages"))

The additional repository can be made available permanently by adding the line above to a file called .Rprofile stored in the home folder of your system (Sys.glob("~") in R returns the home directory).

After that the most recent version of the package can be installed using install.packages:

install.packages("boundaries")

Package updates can be installed using update.packages (make sure that the additional repository has been added before running that command):

update.packages()

Tutorial

The package comes with a vignette describing the basic functionality of the package and how to use it. You can load it with the following command (the package needs to be installed):

vignette("calc_and_plot_boundaries") # Calculate and plot boundaries
