 Themes of the conference

A. Deciding factors

 A.1 The management of sanitation and drinking water supply

  • Strategies for access to water and sanitation, connection with urban planning
  • Elimination of wastes and management of the quality of  the water resources
  • The cost of access to water and sanitation
  • Access to water and sanitation in poor suburban areas
  • Territorial conflicts on water supply
  • Water management standards in megacities

A.2 The position and the role of water in megacities

  • Water and Nature restoration vs artificiality of towns  (Green vs. Gray Infrastructure)
  • Water as a marker of seasons and passing time, in very urbanized human societies
  • Water in the city as a potential for climate change adaptation
  • New water culture: social, cultural, resources

A.3 The resiliency of megacities vs main risks, the effects of climate change and their mitigation

  • Identification and definition of the evolution of the risks in the megacities, in the context of climate change
  • Tools for diagnosis and analysis of the resiliency of megacities
  • Planning and integrating today the possible effects of climate change
  • Population and decision-makers awareness
  • Thinking and designing the urban development and being prepared for extreme risks (hurricanes, floodings, heat waves, droughts). Designing the resiliency of megacities.

A.4 Megacities and new risks

  • Public health, micro pollutants, management scales

A.5 Weight of the assets on present management choices

  • Technical heritage and systems organization: advantage or constraint to adaptation?
  • Asset management, maintenance and durability

B - Solutions

B.1 Forms of innovations by technical approaches

  • Global change and availability of the resources (including energy) and suitability of classic sanitation models. Wastewater added value
  • Water and the « metabolism » of megacities: energy flows, nitrogen and phosphorus flows, food production

B.2 Forms of innovation in economy, in politics, and in institutions

  •  Social inequities and access to water and sanitation: issues and solutions
  • Water management in megacities: inspiring tools for financing the investments and how to use them
  • Existing or future regulatory models at these levels
  • Governance, cooperation and coordination between the actors. Sharing/dilution of power and responsibilities.
  • Case studies of such innovations in megacities

B.3 Human actors and the technology: benefits and limits of smart tools

  • Potential and limits of the smart city concept. Political issues and technical realities. Man/machine complementarity in smart systems
  • New behaviors and perceptions for new water management models ?
  • New issues in data production and data control: methods, technics and ethics

B.4 The paradoxes of sustainable development: incompatibility of objectives, constraints and setting up of priorities

  • Evaluation of sustainable development and water management
  • Sustainable water management in a city: meaning and case studies of public policies related to megacities specific issues
  • Environmental norms and restoration of aquatic environment
  • Environmental norms and preservation of public health within the framework of water policy
