Local agricultural systems in the High Atlas Mountains of Morocco have widely recognized cultural value but are heavily affected by both climate and socioeconomic change. In 2022-2023, I carried out surveys, focus groups, and interviews about changes in livelihoods and agricultural systems in four villages in Imegdal Commune, located in the western High Atlas. My research found that drought is contributing to simplification across agricultural systems and decreased cropped area in the summer. The impacts of drought intersect with ongoing socioeconomic change, and migration is increasing. This thesis consists of two separate chapters, both of which are manuscripts in preparation. The first chapter describes the impacts of change on all components of livelihoods, and the second chapter focuses on how local irrigation management is responding to water scarcity. Both chapters reveal how intensifying droughts threaten the sustainability and viability of High Atlas agricultural systems and associated biocultural knowledge.
