Solution Overview

WWF GreenSpaces is a mobile application to help citizens evaluate their city's green spaces.[1] This technology enables residents to make their voice heard by indicating what they do or do not like regarding their neighbourhood's green spaces, while municipal authorities can directly access visitors' opinions and intervene accordingly to improve the situation.[3] The application helps users discover green oases and find green spaces that suit their interests, such as playground areas, lush greenery, and sports facilities.[3]

Technical Components

The mobile application platform provides functionality for citizens to rate and evaluate urban green spaces through a user-generated feedback system.[1][3] The technology collects visitor opinions and ratings on municipal green spaces, enabling direct data access for local authorities.[3] Users can search and filter green spaces based on specific amenities and features including playground areas, vegetation density, and sports facilities.[3]

Implementation Details

The majority of GreenSpaces application users gave a 6.1 rating out of 10 for the quantity and quality of green spaces countrywide.[2] According to a study conducted by Aristotle University, Thessaloniki has 2.14 m2 of greenery per resident.[3][4] The World Health Organization states that the minimum rate for urban greenery should not be lower than 9 m2 per resident.[3]

Benefits and Impacts

The application provides municipal authorities with direct access to citizen feedback on green space quality, enabling data-driven interventions to improve local conditions.[3] Users benefit from enhanced discovery capabilities to locate green spaces matching their specific interests and amenity requirements.[3] The platform facilitates citizen engagement by providing a structured channel for residents to communicate preferences and concerns about neighborhood green infrastructure.[3]

Climate Adaptation Relevance

This approach addresses urban heat island effects and climate resilience through improved management and expansion of green infrastructure. By enabling systematic evaluation and citizen feedback on green space quantity and quality, the technology supports municipal efforts to increase urban greenery toward WHO-recommended minimums, enhancing climate adaptation capacity through ecosystem-based solutions.

[2]: Greeks are not happy with the quantity and quality of green spaces countrywide, according to WWF Greece's GreenSpaces application with the majority of users giving a 6.1 rating out of 10. [3]: Moreover, using the WWF GreenSpace app, citizens are able to make their voice heard, indicating what they do or do not like as regards their neighbourhood's green spaces. The app can thus be useful to municipal authorities, who can directly access visitors' opinions on the municipality's green spaces and intervene accordingly to improve the situation. Moreover, this app helps users discover green oases and find green spaces that suit their interests, such as playground areas, lush greenery, sports facilities, etc. According to OECD data, there is a mere 0.96 m2 of greenery per resident in Athens, while a study conducted by Aristotle University reveals that the corresponding figure for Thessaloniki is 2.14 m2 per resident. This so, at a time when the World Health Organization (WHO) states that the minimum rate for urban greenery should not be lower than 9 m2/resident. [4]: Another study by the Aristotle University of Thessaloniki put the ratio in Greece's northern port city at 2.14 square meters per person.
