When Small Is Not Beautiful: Neglecting Cumulative Social and Environmental Impacts of Small Dams in Amazon

The number of small dams is growing around the world. Especially in Amazon, there was a five-fold increase in the number of this type of project in the last 20 years. The main drivers behind this boom are economic incentives for renewable energy, saturation of hydropower exploitation capacity in large rivers, allied with the perception […]

South-South Transnational Advocacy: Brazilian dams in the Peruvian Amazon

Congratulations to ADN members Paula Franco Moreira and Simone Athayde who recently published an article on transnational governance in the global south. The article abstract is included in English, Portuguese and Spanish below, along with short biographies of the international, interdisciplinary team. Next week, we will explore the article in depth and discuss connections between Brazil […]

Floating down the river

Speeding down the river in an aluminum boat, we set out to learn about the Tocantins system, and how it changed since the damming. Around 50 people left Palmas at 8 in the morning, headed towards the Lajeado dam, then downstream to visit a family of impacted fishermen, and finally to lunch and swimming on […]

Managing dams for sustainable fisheries

Tropical fisheries are some of the most productive and diverse in the world, and many who live near these fisheries depend on their catch as a primary source of protein. The Lower Mekong Basin is no exception to this, and houses fisheries which provide the people of the region with as much as 75% of […]

New research reveals risks of fragmenting Andes Amazon connections

Rivers of Andean origin contribute approximately half of the Amazon main stem’s annual flow. These rivers also are responsible for a large amount of sediment and nutrients deposited in the lowland Amazon. They also control processes which affect the geomorphology, sediment deposition, and formation of floodplains for thousands of kilometers downstream of the headwaters. The […]

Dams and flooded forests

Often, when we focus on dams and their effects on terrestrial ecosystems, the focus is on deforestation, mainly due to the reservoir creation. This is an important impact of dams, and definitely one that cannot be neglected. But for my PhD research, I keep thinking about the forests that are left behind. The Amazon is […]

A new semester, back to the blog

After most of the summer off and returning to school in the midst of the largest hurricane to hit the Atlantic, we are happy to announce that the Amazon Dams Network blog is back! This semester, we will be featuring some of our previous writers and we will also have some new contributors. It’s my […]

Tropical dams: a green alternative?

In our quest to overcome dependency on greenhouse-gas-emitting fossil fuels, we have been searching for creative ways to provide energy for growing populations. Along with solar, wind, geothermal, and nuclear power, hydroelectric dams show promise in curtailing our need for continuous use of energy sources which emit carbon into our atmosphere. Use of these alternative […]

A new year, a new direction for the Amazon Dams Network/Rede Barragens Amazônicas blog

The new year is a time when people think about the accomplishments of the last year and what progress they will make as they renew themselves. For the Amazon Dams Network/Rede Barragens Amazônicas (ADN/RBA), the last year brought exciting news: we were awarded a grant through the National Science Foundation’s Coupled Natural-Human Research Coordination Networks […]
