Paul Almeida is a Professor of Sociology and Environmental Systems at the University of California, Merced. Almeida’s research centers on the efficacy of collective action at the local, national and global levels of social and political life.  He has empirically examined the timing, distribution, and outcomes of dozens of large-scale campaigns whereby ordinary people and excluded social groups mobilized to protect themselves from the loss of vital necessities such as environmental quality, health care, pensions, water services/utilities, and other socio-economic rights.  His recent work focuses on community-based challenges and responses to climate change.
