Hydroelectric Dams: The Indians Unite

In response to the Brazilian government’s stated objective of issuing a license for the construction of the Belo Monte dam in 2009, the Indians of the Xingu have united once again to confront the threat to their lives.

They are planning a large gathering of the tribes, to run from the 19th to the 23rd May. Over a thousand Indians will join with as many local people in the frontier town of Altamira to press the government to refuse permission for the construction of the dam. They will also use the opportunity to voice their objections to other smaller but no less controversial proposals to build hydroelectric plants on the headwaters and tributaries.Small Riverside Community on the Xingu

The Indians will run the gauntlet of gunmen hired by local landowners who stand to see the value of their land shoot up as the area becomes commercialised.

But they will not be prevented from staging a spectacular display of solidarity, resplendent in feathers and warpaint, as they argue their case.

In 1989, after a similar gathering, the government was forced to climb down when the World bank withdrew funding because of the environmental and social problems the dam will cause.

That was at the peak of interest in the environment. The 1989 gathering brought together Brazilian organisations, international charities, and celebrities, including Sting and the late (and much missed) Anita Roddick. Under the watchful gaze of the international media, the gunmen held back.

There were supporters from many other countries. It was a turning point for Brazil, which was emerging from decades of military rule. New Brazilian organisations were forming, and Brazilians were beginning to stand up to the powerful establishment and its nefarious outer fringes, which inhabited the lawless Amazon.

Today, there are many Brazilians active in the fight to prevent the destruction of the Amazon forest. The Indians have organisations of their own, and are better prepared to take on the government. Now they can speak the government’s language, and they understand more of how the Brazilian world which encompasses theirs operates.

But it will not be an easy battle. Finance for the dam will come from Brazilian banks, raised on the back of the Government’s Programme of Accelerated Growth. This means that the international money which will be used is one removed from the project, and the ultimate providers of the funding may not know (or care) that their money is being used for a project which has already been condemned as an environmental, social and human disaster.

There will be an opportunity to buy stunning photographic quality prints from the expedition, or to make a donation in exchange for postcards.

Hydroelectricity in the Heart of Brazil

Hydroelectricity has been promoted as a ‘clean’ energy source, capable of providing huge amounts of electricity without adding to global warming. Brazil already obtains 80 percent of its electricity from this source.

But the reality is that large dams cause immense disruption to the local environment and produce huge amounts of powerful greenhouse gases. These include methane, which is 21 times more powerful in terms of global warming than carbon dioxide, and nitrous oxide, which is 310 times more potent.

Dams in tropical areas are especially polluting. In the early years, they produce many times more global warming than the equivalent amount of electricity obtained from burning fossil fuels. Even decades after they were constructed, dams in the Amazon continue to generate more global warming than equivalent natural gas power stations.

Dams begin to contribute to global warming before the ground is broken. Manufacture of steel and cement, the core materials used to build the dams, are both significant sources of greenhouse gases.

Once the dam begins to fill with water, greenhouse gas production reaches astronomical proportions because of the decaying vegetation from the trees and plants which are drowned as the water rises. These produce a surge of global warming in the early years, which reduces over time as the drowned organic matter decays, eventually reaching a more or less stable state.

But this stable state still produces high levels of greenhouse gases. Even taking into account natural processes of decay which occur in undisturbed tropical forests, these levels are high. They are several times higher than in a similar-sized natural lake. And they continue for the life of the dam.

Were the dam eventually to be decommissioned and drained, there would be yet another pulse of greenhouse gases, as organic matter trapped in sediment is exposed to oxygen and is attacked by
bacteria and other organic processes, releasing yet another raft of carbon dioxide, methane and nitrous oxide.

On a local level, dams interfere with the life cycles of tropical plants, insects, fish and land animals, destroying the ecological balance of the river basin. Fish can no longer reach their spawning grounds, mammal migration routes are blocked, the annual inundation of riverside land (which brings with it nutrients to feed crops and natural plants growing beside the river) is stopped, and insect populations are affected unpredictably. Aquatic life is damaged by changes in the chemistry of the water trapped in the reservoir, causing many fish species to decline dramatically. The dams create ideal conditions for malaria mosquitoes, and malaria becomes endemic in the areas surrounding dams.

This is but one of the social repercussions. People already living in the area will be displaced; the worst affected will, as ever, be the poorest. Few of the self-sufficient settlers who live along the banks of the Xingu have proper legal title to the land they occupy – and may have occupied for generations.

The experience of people in a similar situation who were affected by construction of the Tucurui dam, only 250 km to the southeast, is not encouraging; over twenty years after the dam was completed many people have not seen any compensation, and are forced to live a marginal existence in shanty towns.

Large construction projects inevitably attract thousands of migrant workers. They bring with them increased deforestation, increased demands on already inadequate local infrastructure, and increased social stress between the immigrant population and the people already living in the area. The problems worsen on completion of the construction, which leaves the new population largely unemployed. Neither the companies involved in the construction and operation of the dam nor the government are prepared to take responsibility for these problems.

Belo Monte, the latest scheme for the Xingu being promoted by the Brazilian government-owned electricity company Eletrobrás , promises to bring all of these problems to the Xingu, with very little benefit.

Further hydroelectric dams are proposed for all of the tributaries of the Xingu. These so-called ‘Small Hydroelectric Plants’ will have a far from small impact on the river and its people, affecting water quality and flow throughout the Xingu basin. The entire ecology of the river will be damaged, disrupting food sources and transportation.

For the indigenous people the dams will destroy their lifestlyes and their very cultures. We must support them in their fight to prevent this unwanted and unjustifiable destruction.

Oooops! Web Server Problems on www.ipcst.org

Our hosting service for the main http://www.ipcst.org website has been offline all day today, and so has our ipcst email. This is the second time this has happened, so we will be moving to a new hosting service. This shouldn’t take too long – I’m hoping to get it done tomorrow – but until it is sorted there may be some emails not being delivered. And of course the main website will not be available.

Since the photo galleries in the links on the right hand side are hosted there too, the picture galleries will also be affected by this. Normal service will be resumed as soon as possible. Please accept our apologies.

New Projects

During the Heart of Brazil Expedition, we identified several projects which we intend to support. I will be posting details of each project over the coming weeks.

The projects we are working to develop are, in brief:

  • Purchase of boat for transporting crops, mainly bananas, from the village to the nearest road.
  • Radio Xingu: provision of broadcast transmission equipment to allow the existing team to broadcast their material instead of sending it on CDs to the villages of the Xingu Indigenous Park.
  • Xingu Indigenous Park: Geographical Information System for monitoring/policing the boundaries of the reserve.
  • Various villages: establish a marketing/research facility to identify markets for products and products for markets, and to facilitate the sale of produce at advantageous prices.
  • Various villages: facilitate growth and expansion of existing honey production by establishing a Fair Trade partner in the UK
  • Establish Fair Trade partner in the UK or USA for chocolate (cacau) production; investigate organic certification; technical assistance in the propagation, collection, transport, storage and processing of cacau.
  • Medicinal plant nursery so that the knowledge of medicinal plants can be safeguarded and extended.
  • Reforestation of recovered land.
  • Assistance with video camera and ancillary equipment for recording cultural and historic material.
  • Assistance with recuperation of traditional crop plant species.
