2 DROUGHT PART OF CLIMATE AND CULTURE RECURRENT TEST INDICATOR AND DRIVING FORCE EREMERGENCY AND CRISIS UNCERTAINTY AFFECTIONS (RISK --RISK FACTOR MANAGE OF AFECCTIONS RISK MODIFICATION) IT IS NOT A SUDDEN PHENOMENON 2

3 Planning investments in infrastructures and in the permanent management of demand Integrated operation of resources and of own hydraulic systems Preventive actions and actions to mitigate the effects of insufficient resources Laws and Protocols to solve situation of emergencies caused by scarcity or by droughts 3

4 HOW ARE THEY FACED? NORMATIVE AND INSTITUTIONAL FRAMEWORK - Reliability criteria - Drought plans requirements - Emergency plans requirements - Basin master plans PREVENTIVE ACTIONS RESOLUTION ACTIONS SOCIAL INVOLVEMENT - Participating - European water framework directive - Suffering - distribution of affections according to the severity 4 INTEGRATED OPERATIONAL PLANNING Preventive planning Mitigation Resolution Within droughts & in between droughts

5 WHICH IS THE KEY? REAL INTEGRATION PLANNING <> OPERATION EMERGENCY <> ROUTINE INSTITUTIONS <> OPERATORS <> USERS RESOURCES <> INFRASTRUCTURES TECHNICIANS <> POLITICIANS <> MEDIA THEORY <> PRACTICE CULTURE <> ECONOMIC DEVELOPMENT <> RISK ACCEPTANCE 5

24 CONCLUSIONS Droughts are one of the components of water management in many areas of the world. Droughts are a recurrent challenge for water services and a significant opportunity for improvement and efficiency. Droughts are integrated in the climate, hydrologic regimes and cultures. They must be integrated in all processes of Planning and Operation of water systems. Real Integration is the key for many processes and for drought prevention and mitigation. Risk, Rigor and Responsibility are the main pillars and the existence of updated operational protocols are one of the most useful tools. Drought management in Madrid (Spain) is a good example of Local Action which could be explored in many other water systems in the world. 24
