The main aim of the study was to assess the differentiation of natural green spaces (NGS) provision across
Warsaw districts. Provision of NGS was measured for two quantitative metrics: availability and accessibility
using a methodology adopted from British Accessible Natural Greenspace Standard (ANGSt). Availability
was measured as a ratio of natural green spaces per capita. Accessibility was calculated as a derivative of
the size of the area and their distance from the residential areas. According to the ANGSt recommendations,
each resident should have access to natural green areas of various sizes (from 2 to 500 ha), located in a radius
between 300 m and 10 km from the place of residence. Our study shows that despite the large share of natural
green spaces in the total area of the city (24.7%), access to NGS and a target of minimum 2 ha of NGS per
1,000 inhabitants in particular Warsaw districts is limited due to the uneven distribution of NGS within a city
structure. In total approximately 60% of the city’s residential areas lack access to NGS over 2 ha at a distance
of 300 m.
