SOSCA is an alliance of individuals and groups involved in promoting the environment, community, and economy of Chichester’s coastal plain. Our district is one of the most beautiful destinations for residents and visitors on the south coast but its unique and fragile environment is under threat from both overdevelopment and climate change. As guardians of an area steeped in history and containing some of the south’s most important wetlands and wildlife habitats, we have a duty to safeguard the Chichester coastal plain for future generations.




We recognise there is a requirement for more housing.  What is not wanted is market led housing of high prices or housing for second homes.  What is needed is housing that is well built, sustainable, and affordable either to buy or to rent. And for local democracy through communities and local government to determine what is needed and where.





The imposition of a new system which gives priority of developers over communities and imposes a blanket ‘algorithm’ to determine the numbers and where they should be built.  The whole planning process would then be determined by central committee within Whitehall.  This process would take NO ACCOUNT of the damage to the environment or consequences of climate change.  It would result in the coalescence of the whole of the south coast and destroy the very environment the government is constantly saying it is protecting.




The Alliance has built up a wide and inclusive support from parishes across the Chichester Coastal Plain and others. Langstone, Emsworth & Westbourne, Southbourne & Nutbourne, Chidham & Hambrook, Bosham, Fishbourne, Donnington & Stockridge, Hunston, Mundham, Aldmonington, Sidlesham, Oving, Tangmere, Pagham,  Selsey Town, East Wittering & Bracklesham, West Wittering, Birdham, Itchenor, together with their many environment groups, residents’ associations and other local organisations. The Alliance works closely with Chichester Harbour Trust, CPRE Sussex, CPRE Hampshire, and other major national organisations. The Alliance has support across the whole of West and East Sussex, East Hampshire and parts of Surrey, Kent and South London.

Having had the good fortune to live and travel abroad for many years it was an obvious choice, on returning to England, to re connect with my childhood in West Sussex.  Seeing this wonderful landscape through the eyes of an adult and parent brought home how important it was to protect such a very special Area of Outstanding Natural Beauty for future generations.

I was born in Bosham so sailing has been and is an important part of my life. It has allowed me to build up a deep understanding of the complexities of the harbours that have given so much to so many.  Being on the committee of The Bosham Association keeps me in touch with the local community as so much of what we admire is now under threat as the continual discharges of raw sewage poison our seas.

I have lived near Chichester for 23 years and grown to love and respect its very special environment.  By working within the corporate risks industry the issues the country faced from climate change became more apparent. This insight was the force behind my being the Organiser of the Going Dutch Project to protect the Manhood Peninsula in 2001 which led to the creation of Europe’s largest coastal realignment scheme – Medmerry Nature Reserve.

There has been a steady stream of concerns over the levels of development across the Chichester Coastal Plain undermining the AONB and my experience has shown the importance of involving the general public in rethinking how to design sustainable communities and neighbourhoods. And so In March 2021 I co-organised a series of lectures for the CDC, parish councils and planners in order to not only raise awareness of the widely known threats the area faces, but also to show that with good design, collaboration, and good decision making there are opportunities to make the area better.

As a sailor the threats to the environment especially around the protected harbours of the Chichester AONB and beyond are of increasing concern. Motivated to become involved in environmental groups to fight the encroachment of so many unneeded developments causing irreparable long-term damage to our fragile wetlands and contributing to the decline in numbers of our local wildlife.

I have lived in Bosham for 20 years and it is more than ever important that we engage with the young to inspire them to protect this fragile and beautiful environment for their future.
