Resumen:
Carbon sequestration
strategies highlight tree plantations without considering
their full
environmental consequences. We combined field research, synthesis of
more than 600
observations, and climate and economic modeling to document
substantial losses in
stream flow, and increased soil salinization and acidification,
with afforestation.
Plantations decreased stream flow by 227 millimeters per
year globally (52%),
with 13% of streams drying completely for at least 1 year.
Regional modeling of
U.S. plantation scenarios suggests that climate feedbacks
are unlikely to
offset such water losses and could exacerbate them. Plantations
can help control
groundwater recharge and upwelling but reduce stream flow and
salinize and acidify
some soils.
