Historical Analysis Exposes Catastrophic Seagrass Loss for the United Kingdom.

The spatial extent of seagrass is poorly mapped, and knowledge of historical loss is limited. Here, we collated empirical and qualitative data using systematic review methods to provide unique analysis on seagrass occurrence and loss in the United Kingdom. We document 8,493 ha of recently mapped seagrass in the United Kingdom since 1998. This equates to an estimated 0.9 Mt of carbon, which, in the current carbon market represents about £22 million. Using simple models to estimate seagrass declines triangulated against habitat suitability models, we provide evidence of catastrophic seagrass loss; at least 44% of United Kingdom's seagrasses have been lost since 1936, 39% since the 1980's. However, losses over longer time spans may be as high as 92%. Based on these estimates, historical seagrass meadows could have stored 11.5 Mt of carbon and supported approximately 400 million fish. Our results demonstrate the vast scale of losses and highlight the opportunities to restore seagrass to support a range of ecosystems services.

'Secret Lists and Sanctions': The Blacklisting of the John Lewis Partnership and the Politics of Pay in 1970s Britain.

In 1977, the John Lewis Partnership (JLP) was blacklisted for breaching the Labour government's pay controls under the Social Contract. As the Callaghan administration struggled to establish economic credibility, extending its reach into the private sector emerged as a political priority. JLP became a test case of government resolve months before the Ford strike of autumn 1978 that ushered in the Winter of Discontent. This article uses JLP records to create a more nuanced picture of the tensions, contestations, and vacillations of pay policy in the late 1970s. By doing so, gaps between policy conception and implementation emerge and intersect; both the business and the government faced constraints in implementing policy, despite powerful beliefs about the integrity of their actions. The article is not primarily a case study, however, and aims to contribute to broader debates. The constitutional significance, rather than the commercial impact, of government sanctions became a keynote of critique of JLP's blacklisting, suggesting that contemporaries recognized this was a confrontation of the political moment between the state and the private sector. By looking from a business's perspective, we also gain insight into how organizations approached, negotiated with, and responded to the government. Recovering the JLP blacklisting episode further shows how business archives offer great promise as resources for political history.

Variability of UK seagrass sediment carbon: Implications for blue carbon estimates and marine conservation management.

Seagrass meadows provide a multitude of ecosystem services, including a capacity to sequester carbon dioxide (CO2) within their sediments. Seagrass research in the UK is lacking and there is no published data on sediment carbon (C) within UK seagrass meadows. We sampled 13 Zostera marina meadows along the southwest coast of the UK to assess the variability in their sedimentary organic carbon (OC) stocks. The study sites were considered representative of sub-tidal Z. marina meadows in the UK, spanning a gradient of sheltered to exposed sites, varying in formation, size and density, but found along the same latitudinal gradient. OC stocks (Cstocks) integrated across 100cm depth profiles were similar among all sites (98.01 ± 2.15 to 140.24 ± 10.27 Mg C ha-1), apart from at Drakes Island, which recorded an unusually high Cstock (380.07 ± 17.51 Mg C ha-1) compared to the rest of the region. The total standing stock of C in the top 100cm of the surveyed seagrass meadows was 66,337 t C, or the equivalent of 10,512 individual UK people's CO2 emissions per year. This figure is particularly significant relative to the seagrass area, which totalled 549.79 ha. Using estimates of seagrass cover throughout the UK and recent UK C trading values we approximate that the monetary value of the UK's seagrass standing C stock is between £2.6 million and £5.3 million. The C stock of the UK's seagrass meadows represent one of the largest documented C stocks within Europe and are, therefore, of important ecosystem service value. The research raises questions concerning the reliability of using global or regional data as a proxy for local seagrass C stock estimates and adds to a growing body of literature that is looking to understand the mechanisms of seagrass C storage. When taken with the fact that seagrass meadows are an important habitat for commercially important and endangered species in the UK, along with their declining health and cover, this research supports the need for more robust conservation strategies for UK seagrass habitats.
