This issue of the WATERLAT-GOBACIT Network Working Papers is a product of the Network’s Thematic Area 2, Water and Megaprojects (TA2). TA2’s membership includes academics, students, practitioners, representatives of social movements and civil society organizations, among others. It has a wide remit, as it covers broad areas related to the social and environmental impacts of water-related infrastructures and operations, as well as extractivist activities, including mining and agribusinesses, among other. TA2 members work on the effects of large-scale water infrastructures, such as dams, river diversions, hydroways, etc., but they also look at the impacts of smaller infrastructures, such as small hydropower plants. Given its broad focus, TA2 has important linkages with most other Thematic Areas. In this issue, some of the articles also contribute to topics covered by TA3, Urban Water Cycle and Essential Public Services, TA6, Hydrosocial Basins, Territories, and Spaces, and TA9, Water and Production. Several of the five articles featured in the issue were originally presented and discussed at workshops organized by TA2 in two of the Network’s International Meetings, the IX International Meeting, Water, rights, and utopias: priorities in the process of democratization of water politics, Joao Pessoa, Paraiba, Brazil, 3-7 September 2018, and the X International Meeting, Struggles over Water: Intersections of Class, Gender and Ethnicity, Concepcion, Bio Bio, Chile, 7-11 October 2019.
