Biodiversity ensures health and food security. Insect pollinators provide a crucial ecosystem service; however, they are under threat. This is a serious cause for concern because pollinators are an integral part of healthy ecosystems. Without them, many plant species would decline and eventually disappear along with the organisms that depend on them, which would have serious ecological, social and economic implications (NIB, 2019). In numbers, biodiversity benefits can add up to billions. Pollinators have a vital role in agriculture – they are instrumental in 35% of global crop production (Willige, 2019). The net worth of insect pollination is estimated to be around 10% of total worth of agricultural production. That adds up to around €153 billion globally and up to €22 billion in Europe every year.

Biodiversity on Urbanscape® Green Roof
There is growing evidence that green infrastructure, including green roofs and walls, can contribute to mitigating the loss of biodiversity.
Green infrastructure can improve the natural conditions needed to sustain thriving pollinator habitats. Green infrastructure is contributing to biodiversity as it provides nature-based solutions, and revitalises urban and industrial areas. Green roofs and green walls act as refuge habitats for numerous arthropod species and allow them to move and disperse within urbanised areas. Together with other green surfaces, such as parks and gardens and by connecting to natural and semi-natural areas in the countryside, they support a network of pollinator habitats in the wider landscape (Bevk D. 2021).
Green Solutions has performed a study on pollinators on Urbanscape Green Roof together with the Slovenian National Institute of Biology (NIB), where two Urbanscape® Green roofs, located in industrial and urban areas, were monitored.
