Neue Studie:

Wie stark die Bäume in den Regenwäldern leiden

Die Baumarten in tropischen #Regenwälder⁣n sind weltweit stärker gefährdet als bisher angenommen. Zu diesem Ergebnis kommen Forscher aus Brasilien, Frankreich und den Niederlanden, nachdem sie die Bestände der atlantischen Regenwälder #Südamerika⁣s untersucht hatten.

#WASSERKRAFT - #HYDROPOWER

Yet another long-term study found that: #Hydropower dams negatively impact the #Hydromorphology (water flows, course, banks) of #Rivers and #Streams => That is, both Hydropower construction and changes in #water levels: result in changes in the "riparian zones" of streams and rivers & were shown to significantly impact: food webs, shading & water temperature - which, in turn, impact and change invertebrates & fish populations. In other words, DON'T build #Dams - they damage the water flow, the banks, the aquatic animals and the humans that depend on them.
And this study was in #Sweden. Imagine the damage multiplied 1,000-fold in the tropics!

How New #Dams in #Amazon Put Entire #World at #Risk
Do you really know how important the intact Amazon is for the #rainforests, #humans (also for #indigenous people...) and #animals there? Do you know what the Amazon basin means to the world and its climate?
Wie neue #Dämme am #Amazonas die ganze #Welt in #Gefahr bringen
Weisst Du eigentlich, wie wichtig der intakte Amazonas für die #Regenwälder, #Menschen (auch für Indigene...) und #Tiere dort ist? Weisst Du, was das #Amazonsbecken für die Welt und ihr Klima bedeutet?
Find out how an increase in hydropower from a series of over 400 planned dams could harm the Amazon Rainforest.

via International Rivers: "Dams and #mining go hand-in-hand in the #Amazon...and they will take this #vital #ecosystem down if we don't stop them."

Would more or other, even better efforts (as, for example, looking at the #MRC activities) "move something", help?
"[...] That’s why there’s growing academic desire for an increased awareness of not just #hydro_politics, but #hydro_diplomacy – that while #water presents obvious potential conflict, it could also accelerate #global #cooperation. [...]"
