Following the ground surveys, there is a need to understand the extent and degree of degraded and degradable lands in Western Kenya for designing and targeting the interventions for counteracting current and future degradation. This will be achieved by combining remote sensing and GIS information, which will eventually lead to a mapping of the survey block areas on their susceptibility to degradation, hence their vulnerability. Four main classes will be formed dividing the land into areas of no, low, moderate and high vulnerability, out of which the last three classes will be subdivided into potentially recoverable through appropriate interventions of low cost (reversible) and recoverable only at high expense (irreversible). This approach has been first developed for the Lower Nyando block and designed under the notion of having to respond to the degrees of data and fund scarcity and is meant to serve as a practicable scheme that can be applied to the remaining blocks.
