6. The hydroelectric threat to the Amazon basin


For decades hydroelectric power was seen as the solution to Latin America’s energy needs. However, serious questions have arisen over its long-term viability. Ecologists warn of the potentially catastrophic impact of dams on the Amazon basin, the most complex network of river channels in the world.


Dams have also had hugely damaging impacts on indigenous and riverine communities. Moreover, major hydro projects have been plagued by massive corruption.

The Synod on the Amazon

A synod is a meeting of representatives of Church communities to discuss issues of doctrine or Church governance.  So far, for most people, so boring.  But when, in February 2019, General Augusto Heleno, President Jair Bolsonaro’s senior security adviser, described October’s Catholic Church synod on the Amazon as ‘relevant to Brazil’s national security’ and having a ‘left-wing agenda’, he was on to something.  Of course, Heleno was expressing a fear deep-rooted in the Brazilian military that the long Amazon frontier makes the country vulnerable to foreign infiltration.  Construction of the Trans-Amazonian Highway started in the late 1950s and always had a strategic as...

Bolsonaro: is there method in his madness?

11 August 2019, São Paulo. Each day the list of outrageous, insulting, untruthful comments by the president grows longer as President Jair Bolsonaro takes aim at scientists, environmentalists,  lawyers, foreigners, gays, indians, civil servants, anyone who crosses his sights, while at the same time declaring his ‘passionate’ love for Donald Trump.  Murdered political activists are insulted, dead torturers are praised.  But is there a method behind his revolving rhetorical machine gun as it targets anyone or any question that happens to attract his attention? Are these all deliberate red herrings to...

With notable melancholy, the 84-year-old says that she does not know how to begin talking about the countless memories she has of her former home in the east of Paraguay alongside the Paraná—one of South America’s great waterways—and of the hardships she has faced since her indigenous community, Tekoha...

I’m gradually getting used to meeting a new organizing team twice a day, so my experience in Germany pushed me outside my comfort zone to begin to appreciate living with the unexpected. We reached Germany after an hour and a half’s train journey and were met at the super-modern station of the mediaeval city of Cologne by...

An Amazon view of Brussels

Letter from Elisa. Rios de Encontro. 4 June 2019 Dear Friends, When I was leaving Marabá, I realised I was entering on a new phase of my life, one which I'd always fought to reach. It’s not just through the knowledge I've gained thanks to the hard work I've put in and the training I've received in the Rios de Encontro project, and of wanting to be someone who is well-informed. But through being an artist, an art educator, and an active member of the afro-indigenous community, capable of defending...
