Résumé
Around the world more than 2 million people die each year due to diarrheal diseases. Poor hygiene and ingestion of contaminated water are responsible for almost 90% of these deaths that mainly affect children. The economic impact of not investing in safe water and sanitation costs 4.3% of sub-Saharan Africa’s GDP. World Bank estimates that 6.4% of India’s GDP is lost on expenses associated with poor sanitation. About 2.2 billion people live below the poverty line at 2 $/day. World unemployment has risen from 170 million in 2007 to nearly 202 million in 2012, of which about 75 million are women and young people. Globally 470 million jobs are needed for new between 2016 and 2030. Unemployment directly affects national GDP. And, GDP per capita strongly explains the Human Development Index. For these reasons, it is crucial to understand water use globally. Offering insights from the perspective of urban water cycle management and the circular economy, this dissertation uses information from official sources to create a global snapshot linking water utilisation with development. Data on the urban water cycle, economy and society in 196 countries is statistically analysed. A factor analysis is performed that defines 5 key latent dimensions in this domain. Based on the factors found, countries were grouped into 6 groups to specify the connections between water use conditions and socioeconomic development. Selected case studies are presented, illustrating the groups of countries found, and highlighting restrictions and advances in the circular economy and urban water cycle management in these countries.
