Research Reports

This section features research papers and reports relevant to, commissioned by, or carried out by the Partnership.


  • Overview of Solent Eutrophication and Recovery January 2023 – This report shows, at the larger waterbody scale for the purposes of the Water Framework Directive, a reduction in the amount of macroalgae within the estuaries of the Solent, compared to the last two decades. The report concludes that recovery from eutrophication in parts of the Solent area is well underway. These changes are the result of a range of nutrient reduction measures introduced at wastewater treatment works and through changes in agricultural practice over the last 20 years.


  • Economic, Employments and Commercial Needs (including logistics) Study Final Report (March 2021) – The PfSH Joint Committee agreed a Statement of Common Ground (SoCG) at its meeting in September 2020. It set outs the strategic issues that need to be addressed in the review of the 2016 Spatial Position Statement and the production of a new Joint Strategy.  The SoCG identifies the evidence base workstreams needed to achieve this and the need to commission the Economic, Employment and Commercial Needs (including logistics) Study to inform the need for employment land allocations in local plans.  Stantec UK Ltd. (supported by Vail Williams) were appointed to undertake the Study.


  • Update to Integrated Water Management Study 2018 – review of methodology and assumptions (2020). This technical note was commissioned by the Partnership for South Hampshire following a decision made by the PfSH Planning Officers Group to review the assumptions on which the 2018 was based. It presents the results of an updated calculation of the increase in TON loading to
    the Solent that could potentially result from projected housing growth in the PfSH area.


  • Integrated Water Management Study 2018. The report was commissioned by the Partnership for South Hampshire (PfSH) to assess any implications from the planned growth in the region on the water resource and water quality environment. For information, in 2019 an OFWAT investigation found that Southern Water had manipulated its wastewater sampling process which resulted in it misreporting information about the performance of a number of sewage treatment sites. This would be need to be taken into account in informing any decisions made based on the findings of the report, if relevant.


  • Centre for Cities published an independent report which looks at how the Solent LEP and PfSH can support economic growth in light of City Deal negotiations and their commitment to develop and new strategic plan for local growth in the Solent area. The report reflects on the successes and strong history of partnership working in the Solent area, recognising however that more needs to be done in these challenging economic times if the area is to ‘punch above its economic weight’ and succeed in its ambition to safeguard and create more jobs and homes.
