Example of nature-based solution for an urban area: Chicago City Hall green roof. One of the benefits is that it mitigates the urban heat island effect, Since around 2017, many studies have proposed ways of planning and implementing nature-based solutions in urban areas. [33] [34] [35]
Urban planners are increasingly exploring nature-based solutions such as temporary lagoons, which can store excess water during heavy rains, and green roofs that help to absorb rain and cool down ...
Nature-based solutions address societal challenges such as climate change or natural disasters by protecting, managing or restoring natural or modified ecosystems for the benefit of humans and nature simultaneously. Examples of nature-based solutions include urban trees, urban green and blue space, and afforested landscapes. [101] [102]
Cities require a very large input of freshwater and in turn have a huge impact on freshwater systems. Urban and industrial water use is projected to double by 2050. [51] In 2010 the United Nations declared that access to clean water and sanitation is a human right. [52] New solutions for improving the sustainability of cities are being explored.
Nature-based solutions (NBS) work with nature and ecosystems to provide benefits to both societies and overall biodiversity. In the context of climate change, they provide adaptation and mitigation options that benefit and support wild species and habitats. In doing this they often contribute to other sustainable development goals. [61]: 303
An example of an ecosystem service is pollination, here by a honey bee on avocado crop. Ecosystem services are the various benefits that humans derive from healthy ecosystems . These ecosystems, when functioning well, offer such things as provision of food, natural pollination of crops, clean air and water, decomposition of wastes, or flood ...
[275]: 8–63 This is for example the case for many nature-based solutions. [ 276 ] : 4–94 [ 277 ] : 6 Examples in the urban context include urban green and blue infrastructure which provide mitigation as well as adaptation benefits.
