  1. OPTIMA October 2004WP01 Requirements and constraints

  2. Objectives • To compile comprehensive lists of water management issues, problems and respective information requirements across the set of case studies • To identify the major institutional structures, actors and stakeholders in water related decision making processes • To list and document the data requirements for the proposed methods • To analyse local data availability against these requirements • To analyse resulting constraints and alternative approaches where necessary

  3. Three building blocks • Data • Model requirements and data availability • Water issues • Characterisation of the case-studies, in a way suitable for quantitative modelling • Stakeholders • Identification of local actors

  4. Data - objectives • To list and document the data requirements for the proposed methods • To analyse local data availability against these requirements

  5. Data – requirements • Geographical Domain Definition • Surface Water River Network Geometry and Topology • River basin objects • subcatchements • aquifers • lakes, reservoirs, hydraulic structures • demand notes • treatment nodes • … • Water quality data • Land use and land use changes

  6. Data – next steps • We will circulate a checklist of data requirements • You will be asked to fill in, indicating data availability and metadata

  7. Water issues - objectives • To compile comprehensive lists of water management issues, problems and respective information requirements across the set of case studies

  8. Water issues - identification • Three components • Water demand • Water supply • Water management • Two types of information • Quantitative indicators (static and dynamic) • Assessment of relative importance, urgency etc.

  9. Demand-related issues This section deals with the economic sectors and spheres of human activity which, through their demand of water resources, exert a pressure on both quantity and quality of the resource.

  10. Water demand – the issues • Total water demand • Total demand and recent trends • Socio-demographic trends and water demand from househoulds • Resident population and demographic trends • Density of population, urbanisation and urbanisation trends • Access to safe, sufficient water supply • Water related diseases • …

  11. Water demand – the issues/2 • Economic trends and water demand (agriculture, industry, energy) • General • income per capita and recent economic trends • Agriculture • water demand from agriculture • irrigated areas • land use and change in land use • Industry • water demand from industry • heavy vs. light industry • Energy production • water demand from energy sector • Importance of hydropower and recent trends • Tourism and recreation • water demand from tourism • tourism and recent trends

  12. Water supply issues This part deals with questions of quantity and quality of water resources and the efficiency of their use

  13. Water supply – the issues • Total water supply and recent trends • Internal surface water and groundwater • Recyclable annd recycled water resources • Precipitations and temperatures • Vulnerability to climate change • Accessibility • Distance of water sources from main demand centres • Infrastructures • Artificial basins • Purification plants

  14. Water management issues This part deals with the existence of clear and efficient mechanisms of water regulation, adequate management resources and effective stakeholder participation.

  15. Water management – the issues • Institutions • Number of institutions dealing with water management • Relative role of private and public operators • Regulation • Characterisation of policies and regulations • Institutional forms of allocation • Water pricing • Prices of water and tariff structures • Infrastructures and technology • Efficiency in water use • Investment in water infrastrutures and water technologies

  16. Water issues - next steps • The list will be presented in the form of a questionnaire, in order to facilitate the collection of data about the quantitative and perceived relevance of the issues considered. • Example: Access to potable water • Percentage of resident population without access • Is the access to potable water a problem in your case?  • Very high priority 5 • High priority 4 • Medium priority 3 • Low priority 2 • Not relevant 1
