Plenary Talk at the 3rd CaBA Training Workshop (Slimbridge)
- 2. TheTamar Plan Developing a shared catchment vision
- 4. It provide us with…. – food and materials – energy / fuel – drinking water It regulates…. – climate gases – flooding & drought It also gives us areas for…. – culture – recreation – habitat for wildlife A catchment provides many Ecosystem Services
- 5. Many pressures act to reduce ecosystem health
- 6. Reduced ecosystem health impairs service provision
- 7. Heavily exploited ecosystem ‘Natural’ ecosystem Provisioning services Regulating services Cultural services Crops Meat Timber Spaces forWildlife Recreation Pest control Water regulation Water purification What services are we currently getting?
- 8. Developing a shared understanding The Ecosystem ServicesWorking Groups (1 – 5) Water Quality: The provision of clean water into the aquatic environment for the benefit of river ecosystem health, recreational safety and drinking water supply. Water Quantity: The regulation of water movement in the landscape to ensure that base-flows are maintained and to reduce the risk of flooding. Space for Wildlife: The protection and enhancement of functional networks of habitat to support healthy wildlife populations and biodiversity at a landscape scale. Carbon Sequestration: The regulation of carbon dioxide and other greenhouse gases through land management. Recreation, Leisure & Culture: The provision of accessible spaces and resources for recreation, leisure and cultural activities and to increase health and wellbeing. A participatory stakeholder-led approach…
- 9. A participatory stakeholder-led approach… What services do we get? Are we getting enough? What areas effect provision? What can we do to provision? Where should they be targeted? How is it funded? What are the outcomes? Are the new sources of funding? Developing a shared vision & a shared language - Habitat creation - Landuse change - Farm infrastructure - Best practice advice - Stewardship - Water Company - Biodiversity offsetting - Flood Risk - Research findings - Spatial data - Monitoring - Reports & plans
- 10. Water Quality Is there a problem…where is it experienced…? Local ecological impacts priority – opportunity – suitability – risk
- 11. Water Quality Is there a problem…where is it experienced…? Local ecological impacts priority – opportunity – suitability – risk
- 12. Water Quality Is there a problem…where is it experienced…? Local ecological impacts priority – opportunity – suitability – risk
- 13. Water Quality Is there a problem…where is it experienced…? Local ecological impacts priority – opportunity – suitability – risk
- 14. Water Quality Is there a problem…where is it experienced…? Local ecological impacts priority – opportunity – suitability – risk
- 15. Water Quality Is there a problem…where is it experienced…? Local ecological impacts Distal ecological, social & economic impacts priority – opportunity – suitability – risk
- 16. Water Quality Is there a problem…where is it experienced…? Local ecological impacts Distal ecological, social & economic impacts Raw drinking water impacts WFD: Article 7 “…avoid deterioration in [water] quality to reduce the level of purification treatment required in the production of drinking water.” priority – opportunity – suitability – risk
- 17. Water Quality – point sources The contribution of point sources of pollution Variety of different pollutants Many different sources Varying contributions in different locations
- 18. Ecosystem services: Water regulation & quality The water cycle is one of the fundamental processes we all depend on – priority – opportunity – suitability – risk
- 19. Ecosystem services: Water regulation & quality The water cycle is one of the fundamental processes we all depend on – Water regulation is dependent on - Direction of water movement: laterally or vertically Rate of water movement / timing of release Interactions with contaminants priority – opportunity – suitability – risk
- 20. Ecosystem services: Water regulation & quality The water cycle is one of the fundamental processes we all depend on – Some land areas play a role in water regulation and water quality - Innate characteristics - Condition/health priority – opportunity – suitability – risk
- 21. Ecosystem services: Water regulation & purification 3 4 3 6 9 62 21 INHERENT RISK PRACTICE Source Receptor We want to understand why water quality is (or is not) degraded in certain locations… +++ Importance/opportunity priority – opportunity – suitability – risk
- 22. Ecosystem services: Water regulation & purification Seasonally wet gley 3 4 3 6 9 62 21 INHERENT RISK PRACTICE Identifying areas of high importance/risk to water regulation - Soil type & condition/practices Free-draining brown earth Gley with impeded drainage priority – opportunity – suitability – risk
- 23. Natural habitat Cultivated land 3 4 3 6 9 62 21 INHERENT RISK PRACTICE Permanent pasture Ecosystem services: Water regulation & purification Identifying areas of high importance/risk to water regulation - Landuse & practice (intensity of use) priority – opportunity – suitability – risk
- 24. Direct connection to watercourse Steeply sloping 3 4 3 6 9 62 21 INHERENT RISK PRACTICE Hydrologically connected Ecosystem services: Water regulation & purification Identifying areas of high importance/risk to water regulation - Location, topography & hydrological connectivity priority – opportunity – suitability – risk
- 25. Water Quality Soil hydrology & condition • Run-off risk • Leaching risk Topography (i.e. slope) Hydrological connectivity • Proximity to watercourse • Flood plain • Surface & sub-surface flow accumulation Land cover • Natural habitats (wetland, woodland or peatland) • Farmed land (tillage or permanent grass) The group identified land most likely to have an impact on water quality: priority – opportunity – suitability – risk
- 26. Water Quality – diffuse sources A well established toolbox of measures to reduce rural diffuse pollution
- 27. Flooding Spaces for wildlife priority – opportunity – suitability – risk
- 28. DroughtCarbon sequestration priority – opportunity – suitability – risk
- 29. Land valueRecreational resources priority – opportunity – suitability – risk
- 30. Bringing it all together…
- 31. Multifunctional priority areas Toolbox of interventions Habitat creation Landuse change Farm infrastructure Best practice advice Integrated vision for the catchment WIN-WIN “Provider saves” Delivery Framework REGULATION “Polluter pays” INCENTIVES “Provider is paid” WHERE? WHAT? WHO? …& who pays?
- 32. We now have a shared understanding of what outcomes will come from a better catchment, who will benefit and importantly who might pay…
