Abstract: Moreover, as the world globalizes, waterrelated risks that were once considered local supply limitations or weather hazards are increasingly seen as regional and global challenges.Globalization can help mitigate local water-related challenges through food trade, financial risk management tools, foreign direct investment, and cooperative disaster warning and response mechanisms.Yet, the negative impacts of these risks can also be propagated through the global economy, and through social disruptions, population displacement, disease, and species and habitat losses. Conceptual framework of the dynamic of water security and sustainable growth Economic growth, hydrological variability, and investment in water securityThis graphic illustrates the relationship between economic growth, hydrological variability, and investment in risk mitigation.It shows that wealthy river basins (green dots, clustered in the upper left-hand quadrant) generally feature simpler hydrologies and larger investments in water security.Poorer basins (red dots, clustered in the lower half of the chart) have invested less in water security, and many face complex hydrologies.The investment required to transition from water insecurity to water security is greatest in those basins with highly variable hydrology (see coloured contour lines).Note: The horizontal axis summarizes hydrologic variability.The vertical axis is a composite indicator of investment in infrastructure and institutional capacity.The dots represent all river basins with populations greater than 2 million, coloured to indicate high (green), middle (yellow), and low (red) levels of GDP per capita (using World Bank definitions).The coloured contours are a linearly interpolated surface reflecting the association between variability, water security investments, and GDP.
