Description

This contract will be focused on delivering the required updates to the EED and the Estuary Guide Website
previously discussed.
Enhanced Estuaries Database (EED):
The required EED updates identified and prioritised, are individual tasks that check and improve the data and 
functionality of the EED.
- Update #1: General check of all EED data, including, but not limited to presentational items such as 
consistency in data processing systems, fonts, etc., plus any equation coding, dynamic links, etc. in the 
original EED and update the Excel spreadsheet format of the EED where required;
- Update #2: Provision of clear explanations and terminologies regarding parameters and their 
calculation methodology (based on the original HRW TR167 report (Manning, 2012));
- Update #3: Description of parameters and units and why they're important (again, initially building on 
Manning, 2012) and scoping of the infographics associated with some key parameters considered 
useful for improving future communications and wider learning of key geomorphological and 
hydrological data and processes for nontechnical audiences reliant on this information;
- Update #4: Scoping of works needed to update the EED to be of relevance to WER waterbodies; and
- General: Developing an agreed maintenance and communications plan for the EED.

This contract was awarded by EA.

Capturing transitional changes in GHG fluxes following peat restoration

There is approximately 1,420,000 hectares of peat in England, with deep peat accounting for approximately 680,000 hectares. However, the majority of our deep peat is degraded, damaged and dried out, with only 13% of deep peat remaining in a near natural state. As a result, peatlands in England emit approximately 8 million tonnes of carbon dioxide equivalent per year, about 2% of England's total greenhouse gas (GHG) emissions. There is an urgent need to re-wet peatlands to abate these GHG emissions to meet our net zero targets. In Carbon Budget 7, the Climate Change Committee recommends that by 2040, peatland restoration should represent over 50% of the emissions savings in land use, and 17% of the savings in the agriculture and land use sector. Peatland restoration targets have been set in the 2023 Environmental Improvement Plan (EIP), with an aim to restore 280,000 hectares by 2050. When peat is restored or re-wet, it moves from a degraded condition category to a restored or re-wet condition category in the UK National GHG Inventory using an IPCC Tier 2 methodology. This move is treated as a step-change without considering any transition between the two steady states. However, it has been hypothesised that this methodology is failing to consider a significant transitional removal of CO2 when a heavily degraded peat is restored. Thus, the CO2 sequestration potential of peat restoration may have been significantly underestimated. To date, the abatement potential of peat restoration has focused only on avoided emissions, however, the potential transitional removal of CO2 could make peat restoration a significant net greenhouse gas removal (GGR), which would be a game changer for attracting carbon finance. The report by Evans et al (2022) on ‘Aligning the Peatland Code with the UK Peatland Inventory’, proposes a model for capturing transitional changes in GHG fluxes post-restoration for CO2. However, this model needs to be refined and validated before it can be used to support investment in peat restoration or to understand the transitional removal of CO2 and its contribution to emissions savings. Therefore, research is required to refine and validate the model approach and to establish the criteria and method for how transitional CO2 uptake could be applied within the National GHG inventory and the Peatland Code.
