This issue of the WATERLAT-GOBACIT Network Working Papers (http://waterlat.org/working-papers-series/) 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. This issue is the result of collaboration between two lines of research being carried out in the TA, and has been edited by Gisela Ariana Rausch, from the National University of Rosario (UNR), Argentina, jointly with Ednilson Gomes de Souza Junior and Simonne Teixeira, from the Darcy Ribeiro State University of Northern Rio de Janeiro (UENF), Brazil. This is third issue published by TA2, we are pleased to present it to the readers, and wish you a pleasant and fruitful experience.
