AB  - A review of scientific literature, specifically in English, was carried out to identify the main impacts
generated by the construction of large dams in Europe, Asia, Africa, Oceania and the Americas. In addition,
a comparison was made between the impacts found in ex-ante studies and those found in ex-post investigations
and significant differences were detected between the impacts identified in the studies before and after the
construction of the projects. Thus, the interest in ecological and socioeconomic impacts, especially negative
ones, predominates in the two types of studies, in contrast to the small number of investigations where the
benefits of dams are evident. Finally, there are common impacts seen in almost all hydroelectric projects around
the world such as the loss of economic sustenance, fertile land, jobs and physical displacement of people,
among others.
