Rio de Janeiro is falling behind on its promise to plant 24 million trees to offset the carbon emissions produced as a result of hosting the 2016 Olympic Games. According to the official counter, just 5.5 million have been planted, and time is running out to get the remaining trees planted before the end of 2015 deadline. Back in September 2012, State Environment Secretary Carlos Minc was so confident of reaching the goal of 24 million trees he increased the target to 34 million. But with less than two years remaining before the set deadline and little more than that More >
The critical period of potential landslides on hillsides is just beginning. Unlike floods, which form immediately during a very large rainfall, landslides generally depend on a slightly slower process, where the determining factor is the level of saturation of the soil. The houses that fell apart last month, in Complexo do Alemão, did so primarily because of fragile construction, and not movement of the soil. When there is heavy rain for many hours or days, water infiltrates the soil at a higher velocity than it seeps out, generally due to percolation or evaporation. The mechanical resistance of soil greatly diminishes More >
Last Wednesday December 11, heavy rains devastated large parts of Rio de Janeiro’s urban metropolitan region as rivers overflowed, areas flooded completely and landslides occurred on some hillsides. It’s estimated that at least four people died and around 6,000 people have lost their home and belongings.

On July 25th, residents living at the summit of the Santa Marta favela, known as “Pico do Morro” (or “Hill’s Peak”), gathered to listen to a presentation by engineer Mauricio Campos dos Santos, discussing the physical geology of where they live.
Resisting for over two years, most residents of Hill’s Peak want to remain in the location where they were born and where they have survived the more difficult moments of favela life. The site hosts one of the most beautiful views in Rio de Janeiro and today is considered a privileged place to live More >
