Contextualizing land use and land cover change with local knowledge: a
case study from Pokot Central, Kenya
Abstract
Rural communities in the drylands of Sub-Saharan Africa (SSA) derive
their livelihoods primarily from their natural resource base.
Unprecedented changes in these environments over the past few decades
are likely to intensify in the future and land users need to develop
sustainable adaptation strategies. This study aims to identify land use
and land cover (LULC) changes and their drivers in a Sub-Saharan
dryland, between 1986 and 2017, by integrating local knowledge and
remote sensing analysis. Local knowledge and environmental perception
are used as the basis for defining LULC classes and for training and
validation of change detection. This study identifies bush encroachment
into former pastures as the dominant LULC change with an increase of
woodland by 39 % and a decrease of grassland by 74%. This process is
perceived as severe degradation by local respondents and is linked to
changing management regimes and unreliable rainfall patterns.
Deforestation and woodland thinning can be traced back to increased
habitation and farming, though the local community also identifies
charcoal production as a driving factor. The integration of remote
sensing and local knowledge provides a holistic view on LULC change in
Pokot Central, Kenya, and offers a solid base for site specific and
actor-centred management approaches necessary for sustainable pathways
of drylands.
