Cidade Estrutural is the second most populated favela of Brasil’s Federal District. Waste picking is a major source of income for its inhabitants who live close to the biggest landfill in Latin America. Cidade Estrutural started as an illegal settlement created by waste pickers in the 60s and grew rapidly during the 90s, mostly due to incentives by political opponents to the Federal District Government of the time. However, the landfill is also a big source of contamination: dust and air pollutants; insufficient waste management and residual water treatment; slurry from organic waste decomposition. These factors pose a permanent health risk to Estrutural inhabitants, specially to children which are vulnerable population.
