Water security in Latin America is at a tipping point – despite holding 30% of the world’s freshwater, millions lack access to safe drinking water. Enter the Latin American Water Funds Partnership (LAWFP), a groundbreaking model of radical collaboration that unites governments, businesses, nonprofits, and philanthropy to drive systemic change in water security.

This chapter explores how Water Funds pool financial and technical resources, implement nature-based solutions, and foster cross-sector partnerships to deliver long-term, scalable impact. With over 26 Water Funds engaging 340+ organizations, LAWFP has protected over 565,000 hectares of watersheds, improved water access, and strengthened community resilience. A compelling case study in multi-sector cooperation, this chapter demonstrates how philanthropic capital can act as a catalyst for innovation, unlocking sustainable financing to combat climate change and transform water security.

Latin America and the Caribbean (LAC) hold one-third of the world’s biodiversity, yet climate change and deforestation threaten this vital ecological powerhouse. Despite the urgency, nature-based solutions (NBS) receive a fraction of global climate finance, while billions flow into environmentally harmful subsidies.

This chapter explores how philanthropy can help bridge the gap and reshape conservation finance by funding high-impact, scalable solutions that protect ecosystems, empower communities, and drive economic transformation. Through case studies of leading philanthropic initiatives – Arapyaú Institute in Brazil, Moisés Bertoni Foundation in Paraguay, and Grupo Argos in Colombia – it demonstrates how strategic investments in forest restoration, biodiversity conservation, and sustainable land use can accelerate climate mitigation and adaptation.
