To test the newly developed Green Factor Tool for the City of Helsinki, with a focus on water management, two test sites (ätkäsaari pilot block and the three model yards in Kuninkaantammi) were created at residential blocks in Jätkäsaari and Kuninkaantammi. The tool itself is an Excel interface that calculates the quantity and quality of the city's green spaces per unit of area, It is part of the larger iWATER (integrated stormwater management) project (Ref 2). Specifically, after testing it on these two pilot sites, it is to support land use planning processes by providing a way to account for the quantity and quality of green space. The project aimed to analyze the cost-benefit of implemented sustainable stormwater solutions, compile stormwater-related planning tools as well as increase and strengthen the capacity of cities to work with stormwater issues (ref. 2).
One of the key objectives of developing the green factor method was to create green urban environments that have social value. Also, functionality was the second most important and cityscape (or landscape value) was the third most important category in green factor scoring.

GIFT-T (Green Infrastructure For Tomorrow - Together!) is a four-year European project of which Medway was one of five case studies. In this project communities, businesses and governments were brought together to facilitate bottom up planning and implementation of green infrastructure (Ref 1). The product of this is a general business plan, and the planned intervention of focus here is the "Thames Terrace Invertebrates - corridors for wildlife" (Ref 2). Hoo Island already has areas that serve well to sustain invertebra species, but as of yet also has underutilised potential in this respect. This intervention addresses the latter.

The Royal Society for the Protection of Birds (RSPB) ran a project to turn Belfast into the first-ever “Swift City”. The Belfast Swift City project aimed to bring nature back to the city and protect the swifts (ref 1). The aim was to find out where the birds are nesting, so work can begin to protect them. Additionally, there was said to be potential for the creation of community gardens in the area of residential buildings undergoing regeneration to aid this project. (Ref 2). As thousands of swifts migrate from Africa and nest in crevices in buildings, nesting boxes were put in a few locations like the parliament building to attract more swifts. (Ref 4)
