Freshwater Ecosystems Services: The ESManage approach and some results
Picture by Giorgio Galeotti
Irish Freshwaters
Significant water quality challenges*
➢ Continuing decline in water quality – 3%
deterioration since 2015.
➢ 44% of water bodies at moderate status or worse =
biodiversity loss & ecosystem services
degradation.
➢ Further loss of high-status river sites- now 17%,
compared to 31.6% in the 1987–1990 period.
*Trodd, W. and O’Boyle, S. 2018. Water Quality in 2017: An Indicators Report. Environmental Protection Agency. Ireland.
‘The declines seen in our rivers’ indicators are an early warning signal that trends in water
quality may be at a turning point and heading in the wrong direction’ (Trodd et al. 2017)
Ecosystem Services Approach
‘a way of understanding the complex
relationship between nature and
humans to support decision-making
with the aim of reversing the
declining status of ecosystems and
ensuring sustainable
use/management/conservation of
resources’
From: Water Ecosystem Services by J. Martin-Ortega, R. Ferrier, I.J., Gordon & S. Khan.
Support of Water Resources Management Objectives?
➢Helps demonstrate the importance of healthy ecosystems
to economies and to human well-being, and account for
those benefits
➢Helps illustrate the links between ecological health/good
water quality and human wellbeing - more easily
appreciated that the WFD goal of ‘good ecological status’
➢Enables a more comprehensive evaluation of the benefits
and costs of measures to improve water quality.
➢Is a framework to better foster stakeholder engagement
and to integrate the knowledge of a range of disciplines &
stakeholder groups.
What is good
status?
ESManage
Incorporation of Ecosystem Services values in the Integrated Management
of Irish Freshwater Resources
Overall Objective
Harness the knowledge and tools required to embed the
ecosystem services (ES) approach into policy and practice in
Ireland for sustainable management of water resources, as
required by the Water Framework Directive.

Methodological Framework (ES ident. to valuation)
Study Catchments
Step 1: Identify the ES provided by Freshwater Resources
➢ Used the CICES framework to identify ES for standing & flowing water
➢ Used a matrix approach to assign their relative
importance (based on existing data and expert knowledge)
The hierarchical structure of the Common
International Classification of Ecosystem
Services (CICES)
e.g. Provisioning Services
Synthesis of current knowledge on Irish freshwater resources in the context of ecosystem
services http://epa.ie/researchandeducation/research/researchpublications/
researchreports/research207.htmlSynthesis
Step 2: Ranking of ES by the General Public
1. How do you use rivers?
2. What benefits from
rivers are important to
you?
mmm
Ecosystem Services %
Bankside activities (e.g. hiking, walking, dog walking) 14
Habitats for plant and animal nursery 13
Pleasure from knowing rivers and river wildlife exists 12
Wildlife watching 11.3
Leisure fishing and angling 11.3
Fish for consumption 8.6
Water sports (e.g. swimming, boating, kayaking) 6
Flood protection 5.2
Control of water borne fish diseases 5.2
Water purification 3.4
Drinking water 2.6
Erosion control 2.6
Renewable energy 1.7
Water for other purposes (e.g. irrigation, livestock) 0.8
Control of water borne human diseases 0.8
Carbon storage 0.8
Step 3: Selecting ES Attributes
Service Attribute
Water quality Presence/absence of scum and filamentous algae
Water health Risk of gastrointestinal infections
Habitat Vegetated (non-agricultural use) riparian buffer
Wildlife Numbers of mayfly species and numbers of dippers, kingfishers & otters
Angling Numbers of catchable fish
Challenges:
➢ Identifying attributes that respond to water quality change
➢ Few relevant data sets to link services and water quality
Scenarios: No change; Intensification
of agriculture; Extensification of
agriculture; Use of riparian buffers
SIGNIFICANT KNOWLEDGE & DATA GAPS
Linking changes in water quality to changes in ecosystem services
Inputs from
management/
land-use change
Change physico-
chemical conditions

Implementation
Strategy
1. ES approach presents clear opportunities to:
➢ Reconnect people to water, conservation of its biodiversity and protection of water quality
– particularly via cultural services.
➢Incorporate a wide range of benefits into decision making related to freshwater
management.
➢Help the Local Authority Waters Programme communicate the importance of water quality
to well being and the economy, and thereby foster bottom-up engagement and action.
2. Challenges remain:
➢Coupling models and creating decision-support tools.
➢Linking pollutants inputs to impacts on ES (especially in a multi-stressor environment)
3. We need to:
➢Collect data on relevant attributes of ES that respond to change in water and habitat quality
➢Initiate application of the ES approach

3. ES Manage Project: Incorporation of Ecosystem Services Values into the Intergrated Management of Irish Freshwater Resources - Profeessor Michael Bruen - Water Event 2019

  • 1. River Boyne at Brú na Bóinne Freshwater Ecosystems Services: The ESManage approach and some results Picture by Giorgio Galeotti
  • 2. Irish Freshwaters Significant water quality challenges* ➢ Continuing decline in water quality – 3% deterioration since 2015. ➢ 44% of water bodies at moderate status or worse = biodiversity loss & ecosystem services degradation. ➢ Further loss of high-status river sites- now 17%, compared to 31.6% in the 1987–1990 period. *Trodd, W. and O’Boyle, S. 2018. Water Quality in 2017: An Indicators Report. Environmental Protection Agency. Ireland. ‘The declines seen in our rivers’ indicators are an early warning signal that trends in water quality may be at a turning point and heading in the wrong direction’ (Trodd et al. 2017)
  • 3. Ecosystem Services Approach ‘a way of understanding the complex relationship between nature and humans to support decision-making with the aim of reversing the declining status of ecosystems and ensuring sustainable use/management/conservation of resources’ From: Water Ecosystem Services by J. Martin-Ortega, R. Ferrier, I.J., Gordon & S. Khan.
  • 4. Support of Water Resources Management Objectives? ➢Helps demonstrate the importance of healthy ecosystems to economies and to human well-being, and account for those benefits ➢Helps illustrate the links between ecological health/good water quality and human wellbeing - more easily appreciated that the WFD goal of ‘good ecological status’ ➢Enables a more comprehensive evaluation of the benefits and costs of measures to improve water quality. ➢Is a framework to better foster stakeholder engagement and to integrate the knowledge of a range of disciplines & stakeholder groups. What is good status?
  • 5. ESManage Incorporation of Ecosystem Services values in the Integrated Management of Irish Freshwater Resources Overall Objective Harness the knowledge and tools required to embed the ecosystem services (ES) approach into policy and practice in Ireland for sustainable management of water resources, as required by the Water Framework Directive. www.ucd.ie/esmanage Mary Kelly-Quinn1, Michael Bruen2, Michael Christie3, Craig Bullock4, Hugh Feeley1, Edel Hannigan1 Fiona Kelly5, Ronan Matson5 , Thibault Hallouin2, Eva Siwicka3 1 School of Biology & Environmental Science, University College Dublin, Ireland 2 Dooge Centre for Water Resources Research, University College Dublin, Ireland 3 Blue Island Consulting Limited, Ceredigion, Wales, United Kingdom 4 School of Architecture, Planning and Environmental Policy, University College Dublin, Ireland 5 Inland Fisheries Ireland, Dublin, Ireland
  • 6. Methodological Framework (ES ident. to valuation)
  • 8. Step 1: Identify the ES provided by Freshwater Resources ➢ Used the CICES framework to identify ES for standing & flowing water ➢ Used a matrix approach to assign their relative importance (based on existing data and expert knowledge) The hierarchical structure of the Common International Classification of Ecosystem Services (CICES)
  • 9. e.g. Provisioning Services Synthesis of current knowledge on Irish freshwater resources in the context of ecosystem services http://epa.ie/researchandeducation/research/researchpublications/ researchreports/research207.htmlSynthesis
  • 10. Step 2: Ranking of ES by the General Public 1. How do you use rivers? 2. What benefits from rivers are important to you? mmm Ecosystem Services % Bankside activities (e.g. hiking, walking, dog walking) 14 Habitats for plant and animal nursery 13 Pleasure from knowing rivers and river wildlife exists 12 Wildlife watching 11.3 Leisure fishing and angling 11.3 Fish for consumption 8.6 Water sports (e.g. swimming, boating, kayaking) 6 Flood protection 5.2 Control of water borne fish diseases 5.2 Water purification 3.4 Drinking water 2.6 Erosion control 2.6 Renewable energy 1.7 Water for other purposes (e.g. irrigation, livestock) 0.8 Control of water borne human diseases 0.8 Carbon storage 0.8
  • 11. Step 3: Selecting ES Attributes Service Attribute Water quality Presence/absence of scum and filamentous algae Water health Risk of gastrointestinal infections Habitat Vegetated (non-agricultural use) riparian buffer Wildlife Numbers of mayfly species and numbers of dippers, kingfishers & otters Angling Numbers of catchable fish Challenges: ➢ Identifying attributes that respond to water quality change ➢ Few relevant data sets to link services and water quality
  • 12. Scenarios: No change; Intensification of agriculture; Extensification of agriculture; Use of riparian buffers SIGNIFICANT KNOWLEDGE & DATA GAPS Linking changes in water quality to changes in ecosystem services Inputs from management/ land-use change Change physico- chemical conditions Impacts (+/-) on selected ecosystem services STEP 4 STEP 6 STEP 8 - Valuation STEP 5 Response of aquatic biota STEP 7 Hydrological modelling…….Bayesian Belief Network modelling

  • 24. 1. ES approach presents clear opportunities to: ➢ Reconnect people to water, conservation of its biodiversity and protection of water quality – particularly via cultural services. ➢Incorporate a wide range of benefits into decision making related to freshwater management. ➢Help the Local Authority Waters Programme communicate the importance of water quality to well being and the economy, and thereby foster bottom-up engagement and action. 2. Challenges remain: ➢Coupling models and creating decision-support tools. ➢Linking pollutants inputs to impacts on ES (especially in a multi-stressor environment) 3. We need to: ➢Collect data on relevant attributes of ES that respond to change in water and habitat quality ➢Initiate application of the ES approach Concluding Comments
