I find it difficult to sort through all the numbers and understand what they actually mean - they're all too simplified and too aggregated to really show what WASH conditions are on the ground for each specific scenario. Transnational comparisons don't really help in showing what was done (the means for measurement are completely obscured and one way of measuring that may have been appropriate for one context may not translate well to another context), nor in what needs to happen. I suppose it's useful for somebody at the international policy level, but it's utterly useless for anybody who is working on the ground or even at the national level where there are large regional discrepancies that are being hidden in these aggregate figures. Furthermore, we should be mindful that it uses political boundaries to assess WASH across different countries, and that these boundaries may not be the best way to differentiate between WASH contexts. Regional identities may be much more fruitful, as they speak to geographic and cultural entities which may exist across political borders and help us better understand appropriate strategies based upon contextual similarities.
