At its very heart, iCASP has been designed to be about working in partnership with others across the region to generate benefits, create jobs and products, to save money and ensure that existing environmental research can be used to address the many different challenges we face.
So, we were delighted to win the University of Leeds’ Sustainability Awards 2020 Outreach category which is all about working beyond the University with a range of external organisations to achieve sustainable impacts. We are fortunate to work not only with our Springboard partners across the whole iCASP programme but with an even wider range of different organisations across our many projects as well.
While our nomination for this award focused mainly on the natural flood management work we do, it is just a small part of the wide range of activity we undertake with valued partners. You can find out more about our range of projects and which organisations and individuals are involved with them in the projects area of the website
As well as the various natural flood management (NFM) projects we have running within the iCASP programme at the moment, we also provide information and guidance to other organisations with their NFM projects.
A key aspect of this is providing advice about initial and ongoing monitoring of NFM measures. This means it’s possible to understand not only the impact the measures have had, but also to influence and inform the design, planning and installation of future measures, on the same and other sites to maximise their effectiveness. We also gather data and carry out analysis on the measuring and monitoring taking place.
Footage released in March from some sites in the Upper Calder valley showed the quantities of water that NFM measures have had to deal with over the past winter, especially when storms Ciara and Dennis arrived on our shores. The video footage below was captured by University of Leeds researchers as part of work being carried out for the National Trust who have been installing NFM measures across some of their land holdings.
But we don’t just provide scientific advice and guidance on measuring, monitoring and installing NFM; through volunteers from the University of Leeds the measures are also being installed in different locations. One of the great things about NFM measures are that they can be installed by members of the community with appropriate guidance and management. Staff and student volunteers who live, study and work at the University of Leeds are involved with several NFM and tree planting schemes in Yorkshire.
Volunteering doesn’t just benefit the communities downstream of where the NFM measures have been installed, but the health and well-being of the volunteers as well. Over the last six months, volunteers from Australia, China, Malawi, Pakistan, Spain, UK and USA have helped build leaky dams and plant trees. The University set up the volunteering scheme to provide staff and students with an opportunity to get out and about, to meet new people and learn new skills all while doing valuable work in local communities near the university.
XiaoXiao Ma, a PhD student researching the poet John Clare, has volunteered on workdays organised by Yorkshire Wildlife Trust to install leaky dams and plant trees. While her research would not seem the most obvious fit with building leaky dams, she was keen to get first-hand experience of working on the land and connecting with nature and her research has subsequently benefited through her growing understanding of the things John Clare was writing about. She outlines two benefits she got from being a volunteer:
“When I work in the field, when I use tools such as a hammer, a rake, or a spade to interact with the land, I can feel the interconnectedness between humanity and nature. We live on the land. Our life relies on the land. We are interdependent
Being a volunteer enables me to make new friends. I met Lee Galston in my first wild work day event and since then we have been very good friends. On the day when we first me, we found we shared common interests such as literature, walking, and nature. We fit in well with each other.”
Xiaoxiao Ma, University of Leeds
Lee Galston who works in the University’s Accommodation Team has also attended volunteer training days and recalls one led by Don Vine from Yorkshire Wildlife Trust as he outlined the work to be done and ensured this was done safely and effectively:
“Don was incredible at what he did, and a huge part of why I’ve enjoyed coming along to the volunteering days. He was great at teaching us how to do the tasks on the day, but he was also generous with his vast knowledge of nature (trees and water, he told me, were his thing, he wasn’t too bothered about birds). Volunteering with him has genuinely changed the way I look at the natural world.
My favourite conversation we had with Don was actually the day Xiaoxiao and I met. She’s writing her PhD dissertation on the poet John Clare and he got really excited talking about Clare’s poetry, which is very nature centric. He told us that he and some friends would play a game of bingo based on Clare’s Shepherd’s Calendar, which has a poem for each month of the year, where they’d try to take a photo of anything they saw that was mentioned in that month’s poem.”
Lee Galston, University of Leeds
Student volunteers at University of Leeds, drawn from 18 different countries around the world, have contributed to installing natural flood management measures on several sites and tree planting projects that have been informed by researchers to ensure they are sited appropriately for the role they are to play. Some of the measures are part of high profile flood risk reduction schemes, such as the Leeds Flood Alleviation Scheme, developed and funded in response to past flood events.
While this news article was being written, we heard the very sad news that Don Vine, who coordinated the activities of many of the volunteers on Yorkshire Wildlife Trust NFM workdays, had suddenly passed away a few weeks previously. He led volunteer workdays that the University was involved with for many years and clearly made an incredible impression on the people he worked with as became clear when I contacted volunteers and volunteer coordinators to write this news piece. The leaky dams he built with volunteers, and the trees planted to help reduce flood risk to communities across the region, remain dotted across the landscape he clearly loved and felt passionate about.
News articles about different NFM projects that iCASP and University of Leeds have contributed to:
It would be hard to have missed the vast quantities of water across parts of the UK over the past few months, but when water isn’t so obvious other ways are needed to track where water is, how much there is and what it is doing.
Monitoring of water is routine and carried out by the
Environment Agency, water companies and local authorities, amongst others, and
covers rivers, water and groundwater levels, pumping stations, overflows,
sewage treatment works and rainfall levels. Many of these monitoring and
gauging stations feed their results in automatically from remote or
inaccessible locations meaning many measurements can be recorded without human
interaction. In many cases measurements are captured every 15 minutes and fed
back to the system daily; data as far back as 10 years ago is available for
some gauges and monitors. Some of the Environment Agency’s gauges have been
taking measurements for almost 40 years
This vast wealth of data is held and used by different organisations and, until recently, had never been combined to create a better understanding of what is happening in a region. Until that is, the Living with Water (LWW) Telemetry Integration project team collaborated through their partnership work to share various data sets.
The LWW partnership are working together with other
organisations in this Catchment Telemetry Integration project to better
understand what data is being routinely captured and where, and will be using
it to identify ways for its use in improved forecasting and responses.
Ultimately the data will be used to influence where future monitoring might be
most usefully installed to provide the most useful data.
The project team produced the first ‘combined data’ maps earlier this year which show the locations and types of all the monitoring stations across Hull and East Riding, including how long they have been operating for.
These maps are provisional results so far, but show the amount of monitoring already taking place across the region.
By sharing this data, and ultimately combining it with
decision-making tools, the project team hope to develop an early warning tool
that will help improve operational preparedness and improve response times at
the outset of a flood risk event.
The cost of the 2015 Boxing Days floods was £47M in Calderdale alone, and the indirect knock-on effects to the regional economy was £179M. This is just from one flood event. In every flood event there is the immediate damage, loss and destruction which is often highly visible; the knock-on effects which are wide-reaching and significant are not always so obvious. With climate change we are likely to experience more extreme weather events that can lead to flooding, so we need to improve our resilience across society.
The Small and Medium Enterprise (SME) sector can be highly
vulnerable to flood impacts. Because a large proportion of the private sector
is made up of SMEs – about 99% of Yorkshire’s private sector is made up of SMEs
– flooding can have a massive impact across the wider region reaching areas
outside those that were flooded.
Our newest iCASP project seeks to address this issue through
supporting the SME sector to become more resilient to the impacts of flooding
so the negative impacts on the wider economy are reduced.
Currently there is a large knowledge gap about the impacts of flooding upon SME businesses; this lack of knowledge extends from the SMEs themselves, through insurers and lenders, local and sub-regional authorities to national government. The effect of this knowledge gap can mean SMEs not understanding how to protect themselves adequately, and insurers or lenders not understanding the risks and so not providing lending or insurance. At the government level this lack of knowledge can manifest as a lack of appropriate funding being included in businesses cases and missed opportunities for evidenced resource allocation and investment in preventive measures.
This project will bring together local authorities and the insurance sector to help them improve their understanding of the impacts of flooding upon SMEs, identify how they can support the sector to become better prepared for floods and help prioritise their responses if and when flooding occurs. A key aspect of the project will be a robust methodology that can be used to assess the direct and indirect costs of flooding. This will enable local authorities (LAs) to carry out future flood assessments and subsequently develop evidenced and robust business plans for funding to support better responses for any future flooding.
“The Leeds City Region Flood Review was published in 2016 and developed in partnership between West Yorkshire Combined Authority/LEP, local authorities, Yorkshire Water and the Environment Agency. The Review and its 19 recommendations aim to implement a more consistent and effective approach to both flood risk management and mitigation, and responding to future flood events across the City Region. Recommendation 3 of the Review relates directly to this project as it confirms the urgent need for a robust regional formula for modelling the indirect economic impact of flooding”.
The ability of lenders and insurers to accurately assess and understand the likely risks of flooding will enable them to understand the right level of risk, develop new products and properly price the current products unlocking access to them for SMEs who may currently be unable to do so. An improved understanding of the effectiveness of different protection and resilience measures could also boost an increase in lending for preventive purposes and thus better uptake of these important measures to improve resilience.
“The work package on insurance will cover an important gap as it provides valuable information to insurers/lenders and surveyors to increase our understanding of SME flood risk. When I hold my regular meetings with insurers, they are bought into the concept of resilience, but cannot move forward meaningfully to acknowledge it without more information and evidence. They want to understand from SMEs what is the real financial impact of a flood. But also, what difference in financial terms has, or could, a resilient strategy make to the cost of the claim. The tool that the project will co-create to assess the effectiveness of resilience measures will be key to identifying the most beneficial strategies SMEs can take to protect themselves”.
Insurance broker specialising in flood risk
As with all iCASP projects this has been co-designed and will be carried out in close collaboration with partners and stakeholders. Co-creation ensures efforts are joined-up to support widespread uptake in the Yorkshire region, and nationally, to spread the benefits of closing this current gap in our knowledge. This exciting new project will push the limits of our understanding on the economic impacts of flooding on SMEs and the effectiveness of property flood resilience measures. And, in collaboration with the City of York Pathfinder project “Yorkshire Future Flood Resilience”, it will work to improve the uptake of Property Flood Resilience across Yorkshire and the UK.
As part of the Natural Flood Management (NFM) work being undertaken on the Calderdale Flood Action Plan, which iCASP’s Calderdale NFM project is contributing to, three sub-catchments in Calderdale are being modelled to improve understanding of how the current land management impacts upon flooding.
On 14 November, Tom Willis held a workshop to explore the modelling work he has been undertaking. Tom has been using SD-TOPMODEL which helps identify which areas of the 3 sub-catchments contribute most to flooding in the lower valley. Knowing which parts of a catchment contribute most to peak flows makes it easier to assess the impact of locating an NFM measure in one place rather than another, and allows prioritisation of those measures that will have the greatest benefits.
Having seen how the model works, workshop participants could apply their knowledge and insight of the catchment into devising different scenarios for the next on-the-ground stage of the project. They then live-tested them during the session to see their impact upon peak flood levels
The next steps in this project will be the creation of a
handbook to assist landowners and managers in targeting the most appropriate
NFM measures across the catchment.
At times when we experience floods, such as those currently devastating people’s homes and businesses in parts of Yorkshire, Derbyshire and Nottinghamshire, it is very common to see people attempting to distill the problem down to a single cause. In complex hydrological systems there is no sense in taking this simplistic approach; rather the whole catchment needs to be considered and we need to think about how we make entire catchments more resilient to extreme events. This is one reason for the ’i‘ in the NERC-funded Yorkshire Integrated Catchment Solutions Programme (iCASP). We work on the understanding that what happens in one area of the catchment affects other parts of the catchment because it is a whole system.
Our work looks at how processes integrate across the entire catchment and while finding solutions to environmental problems we also seek ways to address multiple problems at once, thereby delivering value for money. It isn’t just physical elements of catchment management, there’s a human element too: we work closely with partners and stakeholders on all projects to build relationships and trust and to support organisations to work together in confidence to maximise beneficial outcomes.
Flood Forecasting, and Drought & Flood Risk Mitigation are two of our six workstreams that determine the work we fund. We draw upon the research of several universities in the region including the University of Leeds, University of Sheffield and the University of York to address problems that organisations across Yorkshire are seeking to tackle. This ranges from trying to improve the ability of local councils to respond to weather forecasts by improving the advice provided in a forecast, or implementing measures that slow the flow of water across the landscape so it takes longer to move into the rivers and doesn’t contribute to sudden peak flows.
Restoring the peatland in the upper reaches of a catchment means that rainfall there takes longer to move through and into rivers downstream. Our Peatland Restoration project has developed guidance for practitioners and managers to help their decision-making as to the best restoration techniques to return the system to its normal functionality of water storage and slowing downstream flow. An added benefit of this kind of restoration is that functioning peatland acts as a sink/store locking up carbon that might otherwise be driving climate change.
Natural Flood Management: modelling, mapping and monitoring
Several of our other
projects are on the same theme as this: using natural processes to slow and
store water moving through the landscape to avoid the mass flows and peaks that
cause problems. There are many Natural Flood Management (NFM) pilot projects
throughout Yorkshire funded by government. Our iCASP projects are supporting
these by working with partner organisations to develop modelling, mapping and
We use computer models to understand which parts of a catchment contribute greater quantities of water into a watercourse than other parts, and to understand the role that landscape features – both natural and human-made – may play in this process either slowing or storing water. Our modelling expertise is currently being used in our Calderdale NFM project to understand how three tributaries contribute to water flows further downstream.
Combining rainfall data and
high resolution terrain data, combined with the knowledge gained from site
visits means we can create ‘Opportunity Maps’ that allow an identification of
what the current landscape management means for flood risk and what might be
done in future.
Once developed, Opportunity Maps allow us to identify locations where NFM interventions such as tree planting, aerating soil, buffer strips or leaky dams may best be sited for maximum effect. In the case of our Don Catchment project, we work with the land managers to identify which interventions could be installed by volunteers, what interventions would be best and where our mapping allows us to identify the additional impacts these interventions may play. Many NFM interventions can serve multiple purposes; they may not only slow down the flow of water across the landscape, but they might also improve water quality or provide valuable habitat for wildlife, contributing to improved biodiversity and species richness in an area.
“We feel very privileged to have benefited from our involvement in iCASP, as it has given us access to expertise that has resulted in opportunity maps that are guiding our decision-making in relation to our Hidden Heritage Secret Stream (HHSS) project. These maps identify locations in the landscape where we can have the most impact, and they have also helped highlight the types and locations of NFM interventions that not only slow the flow of runoff, but also reduce diffuse pollution and increase ecological connectivity across the landscape. Our team is using the maps to identify sites for investigation on the ground, and they have been very useful when engaging with our partners and landowners.”
Ed Shaw, Director Don Catchment Rivers Trust
Monitoring the impact and effectiveness of NFM interventions is critical; both to being able to identify what impact is delivered, but also in being able to make the case for funding such measures and for their ongoing maintenance. A key aim of another of our Natural Flood Management projects is to improve the monitoring capability of those using NFM so they are able to carry out rigorous monitoring to contribute to the evidence base for this kind of flood risk intervention.
In our Payment for Outcomes project we are working with the National Trust to build NFM measures into their payment for outcomes trial. Farmers on some of the Trust’s tenanted farms will receive payment for the environmental outcomes they achieve, and this work will eventually inform Defra’s new Environmental Land Management Scheme and show how NFM can be integrated within this.
To maximise all the benefits of this work, we’ve developed a Natural Flood Management Community of Practice (CoP) to bring together people working on NFM to share skills, experience and best practice, build capacity and discuss challenges and opportunities. The CoP meetings draw upon the expertise we are deploying in the NFM projects we work on and also brings together people from across the region – and increasingly from beyond it too – to understand how best to manage their areas of land in the most appropriate ways for our future climate.
Slowing the flow of water through a catchment, and the measures put in place to do this are just one aspect of the measures we are working on. As demonstrated in the last week, at times rainfall is extreme and even if there are lots of interventions in place upstream, the sheer quantity of water is overwhelming, so we also work on improving flood forecasting. Our Enhanced Surface Water Flood Forecasts project worked with a range of partners to trial new forecasting software to assess whether it helped flood risk managers and emergency responders in the decision-making processes they go through in a flood event.
“In response to Defra’s Surface Water Management Action Plan, the Environment Agency and Met Office are scoping a new capability for sharing with responders very short range and rapid update forecasting (“nowcasting”) for the type of rainfall that causes surface water flooding. The Enhanced Surface Water Flood Forecasts project final report, including feedback from the incident response workshop, has provided valuable information and user response insight for the discovery phase of this project and we expect that continued engagement with the iCASP team will continue to be beneficial for understanding user needs and exploring piloting opportunities.”
Graeme Boyce, Project Executive, Flood Forecasting Centre
Our Living With Water Catchment Telemetry Integration project, which the Living with Water Partnership are undertaking in Hull, will bring together remote monitoring data of water flows carried out by several organisations with decision-making software to create a tool that will help deliver operational preparedness for events such as those we have seen in the last week and identify optimal locations for future monitoring. Combining such data collected by these organisations has not been done at this scale before; this way of joint working will be extremely powerful in making higher levels of knowledge available to decision makers and first responders about actions to take and deployment of flood defences.
Our newest project – Bridging the knowledge gap to boost SME resilience – starting later this month will be working on ways to build the resilience of the SME sector. Here in Yorkshire, much of the private sector is made up of SMEs who can be very vulnerable to flooding and the knock–on effects to the regional economy of a flood event can be significant and far-reaching. The project will work with local authorities and the insurance sector to develop a robust methodology for assessing the direct and indirect costs of floods on the SME sector so they are able to tailor their flood assessments and responses appropriately. By providing detailed information on the effectiveness of resilience measures and risk reduction activities, flood risk can be properly priced and managed by SMEs and appropriate support can be given to SMEs to make them more resilient and able to reduce their risks. Local Authorities will be better able to carry out future flood assessments, lobby for additional funds to better prepare for future flooding and, in the event of a flood, prioritise their response in a consistent and timely manner.
This just a snapshot of some of the work we are undertaking to produce solutions to water challenges across Yorkshire, the UK and globally. Our work extends right across catchments, from high and remote peatlands where some of the water that floods peoples’ homes begins its journey, to the streets where we live and the monitoring and forecasting that takes place to try to improve the way we respond, the advice given and the deployment of measures to reduce flood risk.
“Over time, we are increasing the number and diversifying the types of flood management techniques that will reduce peak flows downstream providing new tools to support farmers, villages, towns and cities susceptible to floods.”
Joe Holden, Director, iCASP
The environment is a complex system and we need to work at many different levels to tackle integrated problems. With climate change increasing the likelihood of extreme weather events, it is clear that we need to continue to invest in ways to address resilience and to use a wide range of solutions across the landscape to tackle flooding, rather than think about each component of the system in isolation.
In 2008 Joe Holden and colleagues published research that showed how water running over Sphagnum on blanket peatlands moved much more slowly (often ten times slower) than water running through sedges or bare peat. This spawned a new body of research which has shown how revegetation of peat, particularly if it is possible to get a dense Sphagnum cover, can slow the flow of water during storm events to reduce the flood peak downstream. The research indicates priority areas in the landscape for dense surface revegetation that will generally maximise flood benefits. Given that research has also recently shown sediment release from bare peat strongly influences peatland stream ecosystems this gives added impetus to revegetating peatlands and enhancing Sphagnum cover to achieve maximum downstream benefits for river habitats and flood risk.
Unlike most soil types where movement of water through the
soil attenuates the rate of water loss into rivers, research has shown that
water movement in blanket peatlands tends to be dominated by flow very close to
the surface or at the surface1. This means large volumes of
water move over short periods of time, associated with rainfall or snowmelt,
producing very high flow peaks in blanket peatland rivers compared to the flows
that occur during dry weather2, 3. The condition of the
peatland surface may therefore be crucial in determining the downstream flood
peak during storms.
Over a decade ago research was published that showed how water running over Sphagnum on blanket peatlands moved much more slowly than water running through sedges or bare peat4. This spawned a new body of research which tried to establish whether such effects made any difference to riverflow. This work, which included both empirical field demonstrations5, 6 and modelling experiments7-9, has now shown that revegetation of peat, particularly if a dense Sphagnum cover can be achieved, can slow the flow of water during storm events reducing the flood peak downstream. These effects hold (and can be proportionally greater) even for the very largest storm events10. The research indicates priority areas for the densest revegetation in the landscape to maximise flood benefits. These areas include strips of peatland several metres wide that run either side of streams, ditches and other watercourses, and areas of peatland covering other gently sloping parts of the catchment.
Research has also recently shown that sediment release from bare peat strongly influences peatland stream ecosystems11, 12 affecting both their biodiversity and functioning. This shows that we need to do all we can to disconnect sediment sources from the peatland streams. The most effective way to do so is to support revegetation of peatlands, especially near any watercourses. Thus, targeted restoration work that aims to achieve an end-point with a dense Sphagnum understorey will deliver maximum downstream benefits for river habitats and flood risk, while simultaneously adding resilience to the peatland ecosystems in the face of climate change, drought and wildfire.

Until 15 January 2020, iCASP will be carrying out a survey to better understand people’s views on measures to avoid flooding, in particular, Natural Flood Management (NFM).
We invite anybody who is interested or involved in NFM to take part and share your views. We want to hear about, and better understand, how you feel about NFM. You may have been a volunteer installing NFM interventions, or own land where NFM measures have been installed, you may have walked past some when out and about, or you may not have encountered them at all – whatever your experience, we would like to hear what you think about them.
Over the last few years there have been a wide range of NFM measures implemented across the UK. Here in Yorkshire we have several pilot schemes being trialled and monitored to build up our understanding of the processes, benefits and considerations when installing these kinds of flood measures.
Understanding how people perceive NFM, their levels of knowledge of different interventions and their views on NFM allows us to ensure this is considered when designing future schemes so that they are more acceptable and the benefits are more clearly articulated.
On 28 October, Dr Alison Dunn, lead academic on iCASP’s Invasive Non Native Species (INNS) project gave a keynote presentation at the International Conference on Aquatic Invasive Species about the growing problem of invasives, and the work she is doing to address this.
Because of the growing threat that some invasive species pose to our natural environment, and even in some cases to human health, there’s a real need to stop or dramatically slow their spread. One example of a particularly nasty invasive species is Giant Hogweed , a plant that can cause severe burns on human skin resulting for some people in long-term skin sensitivity problems; the current cost to UK local authorities of tackling this particular plant species is over £365,000 a year. It is this growing problem and cost of dealing with invasive species that is the driver for much of Dr Dunn’s work.
Her iCASP project is breaking new ground by working with local authorities to improve their biosecurity policies and procedures, and embedding this into their routine activities to slow the spread of invasive species. The project draws upon learning from another of her projects working with several organisations in the heart of the Yorkshire Dales to ensure that learning, resources, and successful ways of improving biosecurity are shared.
Local organisations and authorities are not the only people whose awareness and actions Dr Dunn is seeking to change; she gave evidence to the House of Commons Environmental Audit Committee’s inquiry into Invasive Species earlier this year stressing the importance of improved and robust biosecurity:
“Check Clean Dry and Be Plant Wise are flagship campaigns by DEFRA and we have found that where people are aware of those campaigns, their biosecurity behaviour does change, but awareness is not very high”
The report of the inquiry was published last week and biosecurity features strongly in the recommendations from the Committee to the Government. We now need to wait for the government’s response and whether changes are made to policy and legislation longer term.
The INNS iCASP project runs for another year and seeks to develop guidance and biosecurity protocols that will be embedded within local authorities across the Yorkshire region and will ultimately be made available to be used by organisations worldwide to help slow the spread of INNS.
iCASP is working on a project to integrate Natural Flood Management (NFM) into the National Trust’s ‘Payment for Outcomes’ trial. The Trust are undertaking the trial on some of their tenanted farms working with the Yorkshire Dales National Park Authority and Yorkshire Dales Rivers Trust. Their work will help to inform Defra’s new Environmental Land Management Schemes (ELMS). It seeks to pay for farmers for the environmental outcomes they achieve on land they farm.
The iCASP project is focused on identifying opportunities for NFM measures and discussing with farmers how NFM could fit into a payment scheme that would make business sense for them. These valuable insights will help inform future payment schemes which focus on payment for outcomes.
iCASP produced maps of each farm showing the parcels of land tenanted from the National Trust. The land parcels were overlaid on to maps, produced from SCIMAP. These maps show areas of risk related to diffuse pollution (e.g., fine grained sediment) and the connectivity of overland flow of water to the main channel network – together, these maps show which areas of land could benefit from further management. This allows us to generate ‘opportunity maps’ that indicate where NFM interventions might best be sited; for example installation of a leaky dam in a particular location might work well to slow peak flows of water or buffer strips to help reduce sediment (soil) being washed away.
Ground-truthing of the map outputs is crucial to understand the farm in more detail to ensure NFM opportunities are placed in the correct locations. For example, smaller flow pathways that connect sediment and water to the main channels, may not have been picked up during the modelling due to the resolution of data used. Speaking to the land owner is vital at this point to understand how the land is currently used and managed and where there are current issues (e.g., waterlogged soil). This is another layer of information that can be used to ground-truth the modelling output and also verify the locations of potential NFM interventions.
We have recently visited five farms taking part in the trial to do this ground-truthing. This has meant we’ve been able to annotate all the maps to verify the modelling output. This has allowed us to come up with a better understanding of which NFM interventions could be used and their locations on the farms.
The next step in this process will be to meet with all the farmers and other organisations involved in the project to share the knowledge gained by the process and produce final maps of the suggested interventions. Meeting with the farmers will also provide valuable feedback on the opinions of NFM, which interventions the farmers would be willing to install on their land and how these efforts might be incorporated into a payment scheme that pays the farmer for the environmental benefits they produce by installing NFM. iCASP will feed the key points of these discussions to DEFRA to inform the development of ELMS as well as share this useful insight with other projects looking at payment for outcomes (e.g. the Horizon 2020 CONSOLE project iCASP is part of). The National Trust will use the insights to evaluate how NFM could be incorporated into their Payment for Outcomes trial.
