Lake Guidimouni Vulnerability Map with DPSIR-GIS Framework

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.
