Ben Plummer, Climate Emergency Project Officer, attended the meeting to present
the report and assist the Panel with its enquiries. Colchester Borough Council (the
Council)’s first Climate Emergency Action Plan (CEAP) had been published in June
2021, and the Plan had been reviewed both to include new actions and update
existing ones. The new Plan contained more information for residents on how they
could contribute to reducing their environmental impact and tackling climate change,
and this was supported by illustrative case studies.
A new theme on climate adaptation had been introduced to the Plan, which reflected
that many impacts of climate change were already visible and could not be changed,
and the only action that was available was to adapt to the changes in environments.
Work was being carried out with the University of Essex (the University) on a project
called ‘Building With Nature’ which looked at natural sea defences to protect from
rising sea levels and coastal erosion.
Dr Michel Steinke, a marine scientist working at the University, attended the meeting
and gave a presentation to the Panel on a project which had been developed in
conjunction with Council Officers Rosa Tanfield and Ben Plummer. The project was
entitled Building with Nature for Ecosystem-Based Coastal Defence & Economic
Resiliency in Colchester, and the Panel heard about the economic and social
importance of the oyster industry to Colchester. In the past, Colchester’s coastline
had been completely buffered by native oysters, which sadly had now largely
disappeared due to overfishing and disease. Sea rise, coupled with the fact that East
Anglia was sinking into the sea, meant that the coastline needed to be protected.
Hard engineered coastal defences were expensive and unsustainable, and would
eventually fail, and it was hoped that over the coming years, coastline seabed which
was currently muddy and devoid of life would be turned into a dynamic and
adaptable oyster reef which would assist with defending the coastline by reducing
the energy contained in waves which were pounding the shore. Such a living
dynamic reef would constitute a soft-engineered coastal defence which would grow
with sea level rises and be economically beneficial and sustainable. It was
considered that the returns on an investment in such a reef would be maximal, and
could support fish habitats and biodiversity, bolster bird habitats and provide
economic support for local communities.
The Panel heard that it was considered that Colchester was uniquely placed to
tackle such a project, and there was a rich tradition of coastal ecosystem
management in the area which was supported by a large number of community based organisations. Consideration had been given to recycling oyster shells to
create an artificial reef, and the successful use of this method to create natural
oyster reefs had been seen in similar projects in America. The project would be
presented at the United Nations Climate Change Conference 2022 (COP 27), and
engagement had been undertaken with a wide variety of local stakeholders and
other groups working on similar projects in the United Kingdom. The next steps for
the project centred around continuing community engagement and analysis of
community feedback, and the production of a project website and fact-based
summary report.
The Panel heard that it was intended to further support the project though raising
awareness within the Council and continuing to foster good relationships with the
authority. The Project was searching for funding to allow it to continue, and the
Council’s support was considered to be very useful in bidding for this funding. The
project had meaning and benefit for local communities, and it was hoped that the
support of Councillors could be counted on to promote and support the project when
required.
In response to enquiries from the Panel Dr Steinke confirmed that the expectation
was that initial seeding of the oyster reefs would take place in areas where it was
very important to protect the coastline. It may be more economically viable to use
limestone or other shellfish in place of recycled oyster shells for this purpose, as
there could be logistical difficulties in sourcing oyster shells for seeding. Once
seeded, the reef would grow on its own, and would need to be kept separate from
any commercial fishery area. The Panel heard that if seeding material was placed in
the water in the summer of 2023, by September 2023 the first oysters would be
settling on it, producing a benefit relatively quickly.
In response to a question from a Panel Member in relation to the impact of the
project on the existing ecosystem, Dr Steinke confirmed that the Pacific Rock oysters
which were being commercially grown in the estuary were an invasive, introduced
species. Although it had been argued that oyster reefs could have an impact on bird
populations, it was considered that there was insufficient data to prove this. Studies
had been started to measure the output of climate warming gasses from oyster
reefs, including methane and carbon dioxide.
A Panel member considered that there would be significant barriers to the project in
the form of the studies which would be required, and the number of agencies who
would have to approve the work. This meant that there was a need to become more
entrepreneurial and flexible in dealing with climate change. Dr Steinke explained that
he considered that the political support of the Council would be very important to the
project in helping to overcome some of these barriers, and the biggest challenge
which was being faced was that of sourcing additional funding. It was not considered
that the timescale of implementing the project was important, as long as there was
continued progress towards its conclusion.
John Akker, West Mersea Town Councillor, attended the meeting remotely and, with
the permission of the Chair, addressed the Panel. Mr Akker offered his support for
the project, and confirmed that the Town Council was very interested in the proposal.
The project was in its infancy, but the Council’s Officers, together with the University,
had produced detailed plans, and it was considered that there were similarities
between Mersea and successful oyster seeding which had taken place in New York
and South East Asia. West Mersea Town Council would offer its support in any way
it could for the project, and it was hoped that the project would obtain more funding
in the near future.
The Panel discussed the level of funding which would be required to support the
project, and Dr Steinke confirmed that the funding required would depend heavily on
the type of project which was carried forward. Less funding would be required for a
community lead project, and more would be required for a project which was more
technically focused and which required surveys to be carried out, together with work
at sea. A two to three year project was estimated to cost between £750,000 to
£800,000, and would deliver implementation at a small but meaningful scale.
Although similar projects had been implemented elsewhere, local conditions differed,
and although there would be areas of commonality, each area would require different
research to maximise the chances of success.
The Panel offered unanimous support for the project, and was happy for the Council
to continue working with the University and supporting the project wherever possible.
The Panel turned its attention to the proposed CEAP, and wondered what impact
budgetary pressures and the potential lack of grant funding would have on the
progress of the Plan in the coming years. Assurance was offered to the Panel that
although more limited grant funding was available, a set of costed actions was being
prepared, and where the Council had to borrow money to complete projects, it was
hoped that the savings benefits realised from decarbonisation projects would serve
to pay back any loan quicky.
A Panel member considered that when recommending actions which residents could
take to combat climate change, the economic benefits or savings which could be
made as a result of the action be emphasised. This was of particular importance
given the current cost of living crisis faced by many. The Panel was assured that the
direct benefits to residents of any retro-fitting works was being woven through any
communications issued, and Officers were currently investigating obtaining access to
a new Energy Company Obligation Scheme which was being run by Ofgem, and
which would allow funding to be made available for residents on low incomes to
support energy efficiency changes to be made in their homes. Noting the concerns
raised with regard to funding, a Panel member wondered whether there was any
potential to use the government’s Green Investment Bonds as a source of funding,
and Officers would look into this.
Concern was raised that the phasing out of certain weedkillers may have led to the
prevalence of more deep-rooted weeds this year, and Councillors had been required
to purchase their own strimming equipment to deal with these as hand pulling the
weeds had proved impossible. Would the Council ensure that when its weed control
programme was altered, suitable replacements were put in place, to prevent this
happening again in the future?
It was suggested that the concept of biodiversity net gain could potentially be added
to the CEAP, to ensure that where developers were unable to meet the requirement
for biodiversity net gain on their own developments, the Council was in a position to
offer its own projects which could utilise section 106 funding provided in this way,
keeping the biodiversity net gain as local as possible. The Council needed to be proactive in developing policies to provide guidance to developers once the net gain
requirement became mandatory next year, although the Panel accepted that these
policies would likely fall under the remit of the Planning and Local Plan Committees
of the Council.
A Panel member recommended that when communicating with residents, the
Council did not shy away from including scientific detail in communications, as this
detail was of interest to residents.
RESOLVED that: the new iteration of the Climate Emergency Action Plan had been
reviewed, and feedback had been provided.
