In 2020, Johan Östberg and Cecil Konijnendijk founded the Nature Based Solutions Institute (NBSI), resulting from a strong wish to support the greening of cities with the best available knowledge and practice.
Nature-based solutions, ranging from planting a single tree to development of green infrastructure for an entire city or urban region, are needed to tackle the grand challenges human society is facing. They are natural solutions to urban problems.
NBI strives to be an internationally recognized institute for research, development, training, and policy advice within the fields of urban forestry and nature-based solutions.
When engaging in programs and projects of different scope and scale, NBSI can draw upon a global network of experts in the fields of nature-based solutions, urban forestry, and green infrastructure development.
We have introduced the 3-30-300 rule for developing urban forests and creating greener and healthier cities. Everybody should be able to see 3 trees from their home, live in a neighbourhood with at least 30% tree canopy (or vegetation) cover, and be no more than 300 metres from the nearest green space that allows for multiple recreational activities.
A presentation introducing the 3-30-300 rule, prepared for a webinar hosted by the UK Arboricultural Association in May 2021, can be found here.
