The Pantanal and Gran Chaco represent two ecologically distinct yet interconnected landscapes—the world’s largest tropical wetland and one of the most extensive dry forests—which, together, help conserve biodiversity, store carbon, regulate water flows, and provide critical habitat for a wide array of species.

The Pew Charitable Trusts is working alongside national and regional governments, partner organizations, local communities, and Indigenous peoples in Bolivia and Brazil to solidify and expand protection of the region’s extraordinary biodiversity, as well as to promote sustainable land uses that support local residents’ livelihoods. And Pew is also beginning to expand this collaborative work into northern Argentina.

About The Pew Charitable Trusts

Founded in 1948, Pew is a nonpartisan philanthropic organization that uses data to make a difference, addressing the challenges of a changing world by illuminating issues, creating common ground, and advancing ambitious strategies that lead to tangible progress.

Pew works closely with governments, civic organizations, Indigenous communities, and research institutions that share our commitment to conservation, public service, and evidence-based decision-making. These partnerships combine essential expertise, local knowledge, and effective leadership to advance solutions that work within local cultural, policy, and environmental contexts.

Pew’s work in Bolivia

Pew’s efforts in Bolivia focus on the Pantanal and Gran Chaco regions, including key watersheds, Indigenous territories, and protected areas. In collaboration with our partners, this work centers on four interconnected priorities.

  • Strengthening protected areas: Improving the effective management of national, regional, and local protected areas.
  • Creating new protected territories: Securing new conservation designations that expand protections in Bolivia.
  • Advancing Indigenous governance: Supporting Indigenous peoples in strengthening their own territorial governance and management systems.
  • Developing sustainable finance: Supporting the design and implementation of long-term financing mechanisms to ensure that conservation efforts will be ongoing and lasting.

A map of eastern and southern Bolivia focusing on protected areas and Pew program work areas across the Gran Chaco and Pantanal regions. The map highlights 15 distinct numbered conservation zones and Indigenous territories. Different colors and patterns distinguish the categories: Dark green indicates national protected areas; light green shows other protected areas (municipal and departmental areas); orange represents Indigenous conservation areas; and the brown crosshatch pattern indicates Indigenous territories. The map shows major cities including Santa Cruz de la Sierra, Tarija, Villa Montes, Yacuiba, Charagua, Roboré, San Matías, and Puerto Suárez. Highways are shown as yellow lines, and rivers such as the Parapetí and Pilcomayo are marked in blue. International borders with Brazil, Paraguay, and Argentina are clearly delineated, alongside departmental boundaries for Santa Cruz, Chuquisaca, and Tarija.
