Social science research on environment and activism with a cross- or transnational scope (REACTS) is described as a consolidated but confused, stagnant field of scholarship, one which has yet to surpass the comparable state of international studies at large. Previous reviews of the literature in this growing and interdisciplinary research domain have gone so far as so divide it into either its cross-national or its transnational branch, respectively associated with cross-national and environmental social science (CESS), or transnational and environmental social science (TESS). As evidence of stagnancy, once the CESS and TESS branches of REACTS are combined, changes in the cross-national research agenda have been merely the reverse of the transnational one. From 1969–75, REACTS literature covered the themes of population, catastrophic limits to growth, interstate conferences and organizations, North–South relations, survivalist/lifeboat ethics, resource and land conservation, and the social movement organization/non-governmental organization/"third sector." From 1977–91, the issues covered shifted to emphasize violence/conflict, counter environmentalist backlash, seal hunting, whaling, rural energy (improved bioenergy cookstoves), and possibly baby foods, though the earlier concerns with population, (nature) conservation, interstate conferences and survivalist/lifeboat ethics continued. The resistance literature was considerably consolidated and there was a quantitative change in the attention that environmental activism itself received within the pre-existing orientations. In the post-1992 era, the thematic array of transnational REACTS expanded even further as additional issues made it to the agenda in international and environmental studies.
