Wetlandscape Change Information Database for 27 Global Sites

27 wetlandscapes around the world are described in the WetCID database. It combines local survey information with geographic shapefiles and 30-year time series of monthly precipitation, temperature, and annual land-use data. The database was created by Navid Ghajarnia of Stockholm University and is available through PANGAEA.

Use Cases

• Conducting site assessments based on integrated geographic, hydrological, and land-use information.
• Performing cross-regional comparisons of wetlandscape conditions and changes.
• Running scenario analyses on the roles of land use and hydroclimate in whole-wetlandscape functions.
• Studying the dynamics of wetland ecosystem services under global change.

Strengths

• Integrates local survey knowledge with large-scale gridded datasets for 27 distinct wetlandscapes.
• Contains 30-year time series for key hydroclimate variables (mean monthly precipitation and temperature).
• Combines multiple data types: geographic shapefiles, survey information, and time-series data.

Limitations

• Row count and specific file formats are unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• Last update date is unknown; freshness unverified.
