Environmental movements emerged across much of the developing world as part of broader oppositional challenges to authoritarian regimes and statist developmental models that excluded local communities, part of what some scholars termed an ‘environmentalism of the poor.’ In much of the Middle East and North Africa, however, environmental campaigns are generally conducted by coalitions of environmental experts, young activists, and journalists who can navigate the state apparatus, international aid institutions, and media outlets. Campaigns often focus on the inadequate provision of water, sanitation and other public services, threats to public health, pollution, and other areas where expected governmental performance is inadequate. The spread of environmental activism —through network activity involving direct protest, media outreach, and lobbying—can thus be understood as part of the broader generational and political shifts that so distinctly marked in the 2011 Arab uprisings, but were not confined to these. This paper provides a regional analysis of the continuities and changes in collective action around environment and public health issues. Expanding upon the author’s previous work on Egypt, the paper provides a comparative analysis of environmental social mobilization in the region, using primarily information collected on Iran, Lebanon, Egypt, Jordan, and Tunisia. The analysis draws upon media sources, ‘grey’ literature from NGO’s and international institutions, government documents, and other primary sources in Arabic, Farsi, and English. The paper seeks to provide a preliminary mapping of environmental issues and mobilization in the region, analyzes repertoires of collective action, and assesses governmental and popular responses.
