Thought this example of regeneration in Sheffield may be of interest.
"Green Estate is part of the family of third sector organisations that operate from the Manor and Castle areas in South Sheffield . Our story started in 1998 when our inner city area, like many others, was suffering some of the worst effects of social, economic and environmental poverty. However, although in an appalling state at the time it was clear that this area itself had an exceptional history and heritage plus significant areas of uncared for green spaces. This inspired us up take on the role of stewards to what we called ‘our Green Estate’.
The idea was pretty simple - if the relationship between the land and people were made to work again, just as they would in a country estate, we could bring life back to the green deserts and make the green environment a valued and productive asset"
