With Julio César Mejía Tapia, lawyer, activist and researcher from Peru
and María Ximena González-Serrano, lawyer, activist and researcher from Colombia and Switzerland
and the Indigenous Women’s Network for the Protection of Lake Titicaca.
Rivers and lakes are sources of life and are also regarded as cultural foundations. Yet in many places they are threatened by human-induced pollution and overuse.
This webinar focuses on Lake Titicaca in Bolivia and Peru. For the Indigenous communities who live in and with it, the lake is a living and spiritual organism. They respectfully call it “Mamacota” – “Mother Water.” Its catchment area, with numerous rivers, is almost the size of Switzerland and has been an important cultural and habitat in the Andes for thousands of years.
Today, however, this unique ecosystem is under threat: from environmental pollution, mining waste, untreated wastewater and the impacts of climate change. Many people in the region are committed to protecting the lake—especially Indigenous women, who play a central role in local initiatives to defend water. This webinar highlights their engagement, creates space for a deeper understanding of water, and showcases the work of Mission 21 and its partner organizations in the region.
The webinar begins with a contribution from a representative of the Indigenous Women’s Network for the Protection of Water and Lake Titicaca. Julio César Mejía Tapia will then provide insights into the legal and social challenges of protecting water resources around Lake Titicaca. Finally, María Ximena González-Serrano will place the example of Lake Titicaca in a broader global context.
Julio César Mejía Tapia is a legal advisor to the Indigenous Women’s Network for the Protection of Water and Lake Titicaca. He also serves as director of the Institute for Law, Social Participation and Environment (IDEPAM) within the “Eco Legistas” network, as well as the “Pasión Constitucional” initiative. He has extensive experience in strategic litigation in constitutional, environmental and administrative law, and has worked with Indigenous and rural communities in various regions of Peru.

María Ximena González-Serrano is a Colombian lawyer, activist and researcher in social law based in Switzerland. For more than fifteen years, she has worked with local communities on collective strategies to defend territories and rivers against extractive economies and the discharge of toxic wastewater.
