Grass species for range rehabilitation: Perceptions of a pastoral community in Narok North sub-county, Kenya

Land degradation is a global problem leading to a diminished production capacity of the rangelands. The consequence is reduced potential to provide ecosystem services and increased vulnerability to the inhabitants. Biological soil water conservation measures can reverse the trend. Different communities prefer different grass species for rehabilitation as communities vary in location, needs, priorities, preferences and...

This study examines the role of the morphology of applicatives in marking the telicity of applicative verbs in Ruruuli-Lunyala. Applicative verbs in Bantu languages have largely been investigated as allowing a new object Noun Phrase (NP) within the subcategorization of their base verb; this leads to a change of valency with the new Noun Phrase (NP) often giving a certain thematic role. However, less attention has been...
