The Ribeira de Iguape River, one of the most important rivers in the
Brazilian southeastern state of São Paulo, has sources in the Paraná state,
drains from Northwest to Southeast between São Paulo and Paraná states through
the Ribeira Valley (Vale do Ribeira) and reaches the Atlantic Ocean at Iguape,
in the Southern coast of the first state.

To dam or not to dam. written by aes,
June 16, 2007
The original width of Valo Grande was about 4 m (13 feet), just enough to allow the navigation of small boats. But the shortcut radically altered the river flow and accelerated erosion soon took place and the channel width jumped to 200 m (656 feet) only 50 years after its opening.
The huge amount of transported sediments quickly sanded the Mar Pequeno, the sea in front of Iguape, a zone between the town and the Comprida Island. The port has become useless, rice crops dwindled and aggravated by the end of slave trade, the local economy went bankrupt.
The assurity with wich hydro electric proponents speak is almost ludicrous. The power of the hydro dynamic of these 'damn' projects seems to be a matter of prideful indifference.
And nothing can go wrong, what presumptive ignorance of a flowing dynamic that has reached an equilibrium after millions of years.
I used to fly into Hong Kong, one of the things I noticed was there were no trees on any of the mountains, they were all made bare. Kind of an ecological favela.
Lead paint and asbestos were good ideas at the time.

Hong Kong........Kind of an ecological favela. written by ch.c.,

- Comparing the number of trees between a hugely populated area such as Hong Kong and Ribeira Valley, is like comparing the wealth per square meter of these same areas ! Not worth...1 old cruzeiro ! - Have SP and Rio favelas, either downtown or favelas more trees than Hong Kong ? Not sure...in my view ! Just look at aerial views available free in Internet !
In my view Hong Kong, SP and Rio, downtown and favelas are ALL EXISTING ECOLOGICAL DISASTERS !!!

death of the river then the eco system then the valley and so on written by FORREST ALLEN BROWN,

What ever they do it will end up a loss of life to the world and a pocket full of money to a chosen few
just make it deeper and so the water can flow when it rains clear out most of the mangro so the river can breath
like most rivers in brasil all are on there last death rolls .
to many people fishing out the fish to many people shrimping shelling just killing of there furture
and the tree huggers ho dont kill the mangro as they help the fish , well in some cases they do . but in brasils case they trap all the trash bags , tires , wood , and other grabage whitch stop the flow and the rivers sand in near the mouth , and when it rains if floods whitch makes more trash in the water
just choose a river in brasil and look i have been to all and it is the same except where no real citys are
