Today, October 5, marks the World Habitat Day, a day established by the UN in 1985 to talk about if everyone has a safe place to live and fundamental right to adequate housing.
This year's theme is "Adequate Housing for All." The numbers are difficult to ignore. More than 3 billion people lack adequate housing, while over 1.1 billion people live in informal settlements worldwide!
π Adequate housing means secure land tenure, access to safe water and sanitation, drainage, roads and essential services, and also homes that can survive disasters.
This is where GIS matters. What isn't mapped isn't included, and what isn't included is not planned. Satellite imagery helps us understand how settlements grow and transform, while land-use data can reveal where people face risks such as environmental hazards, or inadequate access to basic services.
π€ If you could map your own neighborhood, what would you want it to point out?
