This package is currently work-in-progress. It is going to be used to develop new resources/indicators while {mapme.biodiversity} is undergoing a number of functionality changes. To learn more about the ongoing changes and their current status, please visit the announcement issue.
The branch you are seeing here links against {mapme.biodiversity} v0.6.0.
We will update the resource/indicator functions developed here once a new version is released.
After reaching all milestones in {mapme.biodiversity}, we will decide whether to move the resources/indicators developed here into the main package or if the resources/indicators will be moved here.
Please run the following code to install the required packages:
remotes::install_version("mapme-initiative/mapme.biodiversity", version = "0.6.0")
remotes::install_github("mapme-initiative/mapme.indicators")
The package adds new resources and indicators. It is ready-to-use in a workflow based on {mapme.biodiversity}.
Once the package is loaded in your R session via library(mapme.indicators), the new resources and associated indicators are registered and available for your workflows.
The table below gives an overview of implemented and planned resources/indicators:
| Name | Description | Original Implementation | New Implementation | Data Source | Implemented |
|---|---|---|---|---|---|
| Manageable carbon | carbon stock that is primarily affected by human activities that either maintain, increase, or decrease its size | aggregated to tons per grid cell, then mean per PA | mean per PA | Zenodo | Yes |
| Vulnerable carbon | amount of manageable carbon that is likely to be released through typical land conversion in an ecosystem | aggregated to tons per grid cell, then mean per PA | mean per PA | Zenodo | Yes |
| Irrecoverable carbon | amount of the vulnerable carbon which if it is lost through typical land conversion actions cannot be recovered by 2050 | aggregated to tons per grid cell, then mean per PA | mean per PA | Zenodo | Yes |
| Human footprint | pressure on ecosystems by 8 variables of human impact | aggregation to standard grid, mean per PA | mean calculation directly per PA | Figshare | Yes |
| Species Richness | Number of distinct species | count of unique species within a PA per grid cell, mean over PA | crop polygons to PA and count unique species | BirdLife International IUCN, Global Assessment of Reptile Distributions | Yes |
| Biodiversity Intactness Index (BII) | Todays species abundance compared to modeled abundance in an intact ecosystem | available as gridded product, mean per PA | mean calculation directly per PA | NHM | No |
| Landscapemetrics | Landscape and patch level metrics of landcape intactness | not originally included | mean per PA based on yearly forest cover maps of GFW | GFW | No |
