“Natural Flood Management ‐ an Ecosystem Service”Arlin Rickard (CEO)

Natural Flood Management…

an Ecosystem Service


2

FRAMES – Flood Resilient Areas by Multi‐layered Safety

• Interreg VB North Sea Region

• 3 year project: 2016 – 2018

• Total project budget: €6.9M

• UK Trusts & NFF budget: €1.5M

• ERDF Grant Rate: 50% (effective rate ~46%)

• 3 Pilot Areas in UK• Tees• Trent• Kent

CaBA began life as a Defra Policy Framework initiative that arose, like the Natural Capital Committee from the Natural Environment White Paper “The Natural Choice” in 2011.

Catchment Based Approach (CaBA) ‐

Background


3

Catchment Based Approach (CaBA)

• Catchment partnerships established in all 108 WFD sub‐catchments across England – supported by EA Catchment Coordinators


National CaBASupport Group (NSG)


4

Collaborative Working• Environmental NGO’s & Civil Society

• Government & Agencies (Defra, EA, Natural England)

• Water Companies and 2nd sector business

• Landowner & Farmer Representative Groups

• Academia

• Local Authorities

• Local networks

• Local Communities etc

• Catalyst to bring a range of local stakeholders together

• Consensus – often between stakeholders with conflicting views & interests … integrated Catchment Plan

• Identify solutions to issues that are not easily addressed through direct regulation ‐Cultural change

• Co‐delivery of action on the ground

• Leveraging of funds from diverse sources

• Getting more for less – “synergy”

CaBA Benefits


5

Multiple synergies

• Improved Water Quality and Quantity

• Flood Risk Management

• Biodiversity

• Climate Resilience

• Green (& Blue) Spaces

• Community Health and Well‐being

• Sustainable Business & Agricultural Growth

• Socio‐economic including urban re‐generation

Community Engagement is key to CaBA success!

Training, webinars and tech support to help CaBApartnerships make the most of online and mobile data sharing technology

Using Story Maps to engage different audiences and stakeholders around catchment management

Combining government Open Data with local data to create a weight of evidence for collaborative action

Using mobile data capture technology to fill evidence gaps and report issues

GIS‐based education resources linked to the national curriculum to link schools with local CaBApartnerships

Catchment Plans • Clear sense of direction driving

collaborative action –“Defra down ~ Community up”

• Local stakeholders collectively prioritise action

• Catchment Plans can take on different but equally effective forms

• Plans capture quantitative evidence and data (linked to RBDMP’s)

• Can incorporate a series of project proposals (not just water)

• Rationale, Outcomes, Timelines, Roles & Responsibilities

• Build confidence in the partnerships as a delivery partner

CaBA Partnerships provide an ideal vehicle to mobilise debate and action bringing together flood threatened communities and those organisations (& individuals) able to enact mitigation

Managing Flood Risk at the Catchment Scale


17

Improving the weight of evidence required to deliver catchment scale NFM.

Key lessons learnt from the modelling work:

Large scale NFM delivery could significantly reduce flood risk & compliment traditional engineering even in extreme events.

Existing natural capital within the catchment is already providing significant flood risk benefits.

Collaborative modelling, in which the community help to identify NFM opportunities, can act as a powerful catalyst for catchment scale delivery of NFM.

Strategic NFM benefit maps (Derwent) + local opportunities

Local opportunities for river improvement to store flood water in

the Cocker sub‐catchment

Local opportunities for woodland planting in the Cocker sub‐

catchment

Healthy soils provide, both food, plentiful

supplies of clean water & flood risk reduction

• Estimated 2.2m tons of soil eroded annually in the UK• Soil losses are >20x the rate of recruitment

• Soils hold > third of the worlds organisms• Typical “cricket ball” of soil has 100 billion bacteria;

10x1000’s small organisms; 100’s km of hyphae fungus • 25 species of earthworms in the UK (Darwin’s plough)• Healthy soils have >2m earthworms/ha releasing 80kgsN/ha • Worlds soils hold 10x more carbon than worlds forests• UK signed up to Paris COP 2015 “4 per 1000” – increase soil

OM by 0.4% per annum to combat CC

PES Funding Mechanisms?

Loss of EU Funds & declining government grant in aid, means innovative funding sources are essential to maintain and improve the environment

• Water Co’s and PR19 ‐ catchment investment• Water for abstraction ‐Cap & Trade• Phosphorus / Nitrate ‐Cap & Trade• Community co‐funded Natural FRM • Healthy soils & carbon sequestration ‐ incentives • Natural Capital ‐ farm landscape features – e.g.

wetlands, woodlands, hedges & buffer zones
