Water is the blue thread of integration connecting people, places, and progress. It is essential to the well-being of children and their communities and creates pathways out of poverty. Water transforms lives by driving economic growth, food security, environmental resilience, safe healthcare, and educational success. Mapping the Blue Thread is World Vision’s 2026 to 2030 global business plan to deliver adaptive water, sanitation, and hygiene (WASH) solutions for a better, healthier world across 42 countries. Our data-driven approach enables country WASH teams to deliver targeted, location-specific strategies that maximize impact, effectiveness, and sustainability.
