Description
Mahamadou Salifou Karimou Barké developed a spatially explicit DPSIR-GIS framework to assess climate resilience at Lake Guidimouni, a Ramsar wetland in Niger's Zinder Region. The analysis integrates remote sensing, spatial autocorrelation modeling, and NDVI-based carbon proxies to produce a fine-scale vulnerability map. It was last updated on April 24, 2026.
Use Cases
Generate vulnerability maps based on integrated biophysical and socio-economic dimensions of change.
Analyze land-use transitions, such as cropland to aquatic grassland, based on object-based image analysis.
Model the proliferation of invasive macrophytes like Typha domingensis using spatial autocorrelation.
Assess exposure of irrigated agriculture to flooding and vegetative invasion based on hydrological stress indicators.
Evaluate stakeholder perceptions for resilience strategy validation based on participatory co-production methods.
Strengths
Includes a fine-scale vulnerability map capturing both biophysical and socio-economic dimensions.
Quantifies land-use change, reporting 77.2 hectares of irrigated cropland transitioned to aquatic grassland.
Identifies specific threats, noting 42.5% of irrigated agriculture is exposed to flooding and invasion.
Limitations
Column-level documentation is absent; field semantics must be inferred after download.
Row count is unknown, which may limit suitability assessment.
The dataset is a 672.7 KB DOCX file, suggesting limited scope and potentially summarized results rather than raw data.
