🗞️ Driving the news: Dams, once hailed as symbols of economic prosperity, are now scrutinized for their significant ecological impacts
• Their construction disrupts river ecosystems, contributes to greenhouse gas emissions, and poses risks of catastrophic failures, as evidenced by recent incidents in Canada, the US, and China
🔭 The context: While dams support agriculture, irrigation, and hydroelectric power, they also cause soil erosion, species extinction, and other environmental damages
• They interfere with natural river flows, impacting aquatic life and riverine biodiversity, and are responsible for substantial methane emissions from trapped organic matter
🌍 Why it matters for the planet: The environmental costs of dams are increasingly recognized as outweighing their economic benefits
• They contribute to climate change and disrupt natural ecosystems, challenging the sustainability of such infrastructure in the face of global environmental crises
⏭️ What's next: There's a growing call for strategic planning in dam construction to balance human needs with environmental protection
• Individual actions, such as conserving water and energy and voicing concerns about new dams, can contribute to a more sustainable approach to managing water resources
💬 One quote: "It would be a grave mistake to continue to finance those [dams] with the impression that they were part of the solution to the climate crisis” (Kate Horner, Executive Director of International Rivers)
📈 One stat: The world’s reservoirs lose about 170 cubic kilometers of water to evaporation annually, equivalent to 7% of all freshwater consumed by human activities
