Rainwater management practices are often promoted with little regard for the site-specific biophysical characteristics and local socio-economic and institutional environments.

To promote rainwater management more successfully, a paradigm change towards promotion of location-specific interventions is needed. Beyond biophysical suitability, successful implementation crucially depends on farmers’ willingness to adopt a practice.

‘Similarity analysis’ is an approach that presents and matches geospatial and other data so successful interventions in a location can be mapped to other locations with similar biophysical, socio-economic and institutional characteristics within a basin. Mapping similarities and differences can help us identify promising locations for technologies and other interventions to be spilled over for wider impact.

The report ‘Similarity analysis for the Blue Nile Basin in the Ethiopian highlands‘ :

  • Presents the available spatial data for the Blue Nile Basin in the Ethiopian highlands.
  • Develops a methodology that allows identifying locations within a landscape that have similar biophysical, infrastructure, socio-economics, and governance characteristics relevant to rainwater management.
