1. OPTIMA October 2004 WP01 Requirements and constraints

2. 1 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. 2 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. 3 Data - objectives  To list and document the data requirements for the proposed methods  To analyse local data availability against these requirements

5. 4 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. 5 Data – next steps  We will circulate a checklist of data requirements  You will be asked to fill in, indicating data availability and metadata

7. 6 Water issues - objectives  To compile comprehensive lists of water management issues, problems and respective information requirements across the set of case studies

8. 7 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. 8 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. 9 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. 10 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. 11 Water supply issues This part deals with questions of quantity and quality of water resources and the efficiency of their use

13. 12 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. 13 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. 14 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. 15 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 priority5 High priority4 Medium priority 3 Low priority2 Not relevant1
