Thanks to our supporters last Giving Tuesday, in 2023:

  • RioOnWatch will complete the year with over 90 publications and video reports primarily by favela-based journalists covering numerous subjects with a special focus on climate justice and democracy. We also trained over 20 young favela reporters in community journalism and further consolidated our role as media watchdog and defender of favela narratives.
  • The Sustainable Favela Network ran a series of favela climate memory circles, uncovering an interconnected and rich history of environmental concerns and adaptation and producing a touring exhibition. We also launched energy and water justice data in 11 favelas across Greater Rio, data used by the state’s Public Defenders’ Office in a public lawsuit against the water utility that fails to guarantee water access, and published a one-of-a-kind Energy Efficiency in the Favelas report. A 10-week solar energy training culminated in an emotional installation of solar panels that is resignifying how a woman’s association sees its future. And our first national exchange was held with indigenous, quilombola and favela leaders from across Brazil.
  • The Favela Community Land Trust program celebrated its 5th anniversary welcoming international CLT leaders to Rio for an event attended by 550 people in person and online in a year marked by continued national and legislative expansion. After Rio’s civil society showed up over and over again at public hearings to defend it, the CLT is likely to pass in Rio de Janeiro’s new Master Plan later this year. Several pilot communities are finalizing setting up their associations.
