Recently published paper titled Not only climate change: mobility, vulnerability and socio-economic transformations in environmentally fragile areas of Bolivia, Senegal and Tanzania by Cecilia Tacoli (2011) argues that “migration is better defined as an adaptive response to socioeconomic, cultural, political and environmental transformations, in most instances closely linked to the need to diversify income sources and reduce dependence on natural resources. Drawing on case studies in Bolivia, Senegal and Tanzania, it  describes how environmental change at the local level interacts with other factors to shape migration patterns, and how such patterns in turn affect the livelihoods and resilience of individuals, households and communities in areas experiencing the impacts of climate change in the form of desertification, soil degradation, disrupted rainfall patterns and changes in temperature.”
