Development of wetlands assessment methodology is one of the outputs of a consultancy project on Wetlands Vulnerability Analysis using GIS Analysis Tools. The project is being implemented as part of the Global Monitoring for Environment and Security (GMES) & Africa Programme, specifically, under the component awarded to the Regional Center for Mapping of Resources for Development (RCMRD) and partners.
The aim of Wetlands Vulnerability Analysis is to enhance the Wetlands Monitoring and assessment using geoinformation processing tools and techniques.
The analysis is targeting 10 eastern Africa countries, namely: Djibouti, Eritrea, Ethiopia, Kenya, Mauritius, Rwanda, Somalia, South Sudan, Sudan and Uganda.
The main objective is to develop a methodology and tools for the analysis of wetlands. Specific objectives:
- To review current wetlands vulnerability assessment methods
- To develop a methodology based on EO data and Spatial/GIS tools using scientific knowledge as well as experience from the Eastern Africa region.
A multi-criteria aggregation approach (MCA) of individually weighted indicator data was used to generate Wetland Vulnerability index:
Where
$wvi$ is wetland vulnerability Index,$w_i$ is the weight of the indicator and$v_i$ is the Indicator.
