Sometimes there are positive unintended effects. Near my city, there are a number of small hydro plants and dams, built before a grand national syncrhonized system was ready.
While the dams were built inside very preserved forests, so there was initial damage, the surrounding area (tens or hundreds of sq. km) were put under protection to guarantee the water supply, so no reforestation, no agriculture, etc. Now even the surrounding areas are in better shape today than in the 1960s when the dams were built.
Of course it helps the individual size of each plant is small (tens of MW, tops).
