While access is mainly an issue for developing countries, the sustainability aspects are key for all.
The main challenge for access remains in the poorer developing countries, particularly in rural areas. Within the first target that aims for universal and equitable access to safe and affordable drinking water to all, significant gaps remain. Sanitation is less developed than drinking water, and the same geographical pattern is seen as for safe water scarcity. The situation is likely to improve, but not disappear, over the next 15 years. Water sustainability is an issue in large parts of the world, correlated with precipitation patterns, but not well associated with normal developing-developed country status.
ROW gets a red rating, with significant challenges in both water and sanitation. BRISE and China both get yellow ratings, but with China on the borderline to achieving a green rating. USA and OECD score green.
Understanding the score
Five regions: USA, OECD (excl. USA), China, BRISE (Brazil, Russia, India, South Africa and 10 other emerging economies), ROW (rest of the world).
Green light: Goal likely to be reached.
Orange light: Goal not likely to be reached, but more than 50% of the gap between today's status and the goal is likely to be closed.
Red light: Goal not likely to be reached, and less than 50% of the gap between today's status and the goal is likely to be closed.
