In a report published in March, CPRE London are concerned for a number of open green spaces in London. The say:
There are currently more than 50 precious green sites across London threatened with development. These include parks, recreation grounds, open fields, small green spaces in housing estates, sports fields and nature reserves. Many of these sites have protected Green Belt and Metropolitan Open Land status.
This situation is extremely alarming. London only has half the green space it needs for a population its size [source: https://www.fieldsintrust.org/green-space-index]. And the limited green spaces we have are coming under more pressure since the start of the pandemic despite their greater use and value [source https://www.cpre.org.uk/about-us/cpre-media/green-spaces-and-community-thrive-during-lockdown/]. Additionally, proposed development in the Green Belt threatens to create sprawling, car-dependent housing estates. These destroy our countryside while simultaneously adding to congestion, pollution and carbon emissions, at a moment in time when London urgently needs to tackle climate, air quality and health crises.
