The town of Todos Santos is located between the Pacific Ocean and the Sierra de la Laguna mountain range in the west end of the Baja California peninsula. The fresh water reserves in the region are supplied by various aquifers that descend from streams located in the upper parts of the Sierra de la Laguna.  The Sierra was declared “Biosphere Reserve” in 1994 because of ts rich biodiversity and the importance of its environmental services for the region. The Sierra de la Laguna Biosphere Reserve, as it is called, has the highest levels of rainwater catchment statewide (700mm compared to 100mm-150mm in other parts of the state), which is critical given that Baja California Sur is listed as the driest state in Mexico.

Roger Herrera Tapia is the Todos Santos Waterkeeper.  Upon moving to Baja in 1996, Roger fell in love with the region's natural beauty. He’s an experienced rock-climbing, kayak and surf instructor with over 20 years in environmental education. After graduating with a degree in business and management from the Universidad Autonoma de Baja California, Roger worked as an operations and project manager for the US-based National Outdoor Leadership School (NOLS), an international nonprofit school that leads wilderness expeditions that teach technical outdoor skills, leadership, and environmental ethics. The skills he picked up while working with adults, Roger now uses when educating young leaders-in-the-making. He leads an outdoor leadership program for middle and high school students from a local school and leads two annual ocean-mountain wilderness camping trips.
