Groundwater overuse puts Brazil’s river flow at risk, study finds

3 weeks ago | news.mongabay.com | Sarah Brown

A recent study reveals the potential risk of river water flowing underground in Brazil due to high groundwater extraction, which could lead to losses in streamflow. Researchers found a correlation between groundwater use and river flow reductions, particularly in dryland areas. Overexploitation of groundwater could severely affect Brazil’s agriculture, energy production, and ecosystems, with illegal and unregistered wells likely contributing to the problem.

A young jaguar that conservationists have named Tañhi Wuk has become the third male to be collared and released into Argentina’s El Impenetrable National Park as part of efforts to protect the species. Collaring jaguars provides vital tracking data that help in conserving their populations and preventing poaching, while also promoting coexistence with local communities through education.
Endemic fish wiped out in Brazilian Amazon hydroelectric dam area, study finds

1 month ago | news.mongabay.com | Sarah Brown

The construction of the Balbina hydroelectric dam in the Brazilian Amazon led to the loss of seven endemic fish species in the Uatumã River, researchers have found. The hydroelectric dam has transformed the Uatumã River’s fast-flowing habitats into static environments, making them unsuitable for certain fish species. Researchers call for the investigation of unaffected tributaries, such as the Jatapu River, as possible refuges for the missing species and future conservation efforts.

The United Nations framework for reducing emissions by protecting forests in less-industrialised countries, known as REDD+, isn’t doing enough to prioritise Indigenous peoples in the Amazon. That’s the finding from a new study, which proposes a dozen principles for giving local and traditional communities, the long-standing stewards of those very forests, more decision-making power within REDD+.

Climate policies like REDD+ often fail to prioritize Indigenous peoples, undermining their effectiveness in tackling the root causes of deforestation and climate change, according to a recent study. The authors propose 12 principles to improve climate policies, based on themes such as supporting Indigenous territorial defense and their rights, encouraging Indigenous-led climate initiatives, and directing climate funding to these populations.
