The document discusses the need for societies to rethink the relationship between spatial planning and water management as urban areas intensify and expand their use of land and water. It notes there are governance challenges at the vertical frontier between levels of government, the horizontal frontier between public and private actors, and the fluid frontier of trans-boundary resources that require legitimacy, fairness, efficiency and effectiveness across scales and boundaries over the short and long term.
