Treasuring trees to make cities greener and healthier
First World Forum on Urban Forests launched today 28 November 2018, Mantova - Forests and green spaces can help create more resilient and sustainable cities,
and address the challenges of an increasing urban population, is the message FAO delivered today to participants of the
first World Forum on Urban Forests. "More sustainable models of urban growth are urgently needed," said Hiroto Mitsugi, FAO Assistant Director-General, Forestry Department at the opening of the forum.
He also called on participants to endorse a set of urban forest solutions - listed below and launched at the forum - all aimed to create greener, healthier cities.
The Forum -
Changing the nature of cities: the role of urban forestry for a green, healthier and happier future - is organised by FAO, the Municipality of Mantova, the Italian Society of Silviculture and Forest
Ecology (SISEF) and the Politecnico di Milano. The forum provides a platform for sharing positive examples of urban forest planning, design and management around the world, and an opportunity to firm up participants' commitments to harness
the benefits of forests. Over 600 people - mayors, academics, foresters, landscape designers and town planers from more than 50 countries - are set to participate in the forum (28 November-1 December). Why invest in urban forests and green spaces?
Cities occupy only three percent of the planet's surface, but consume 75 percent of natural resources. Over half of the world's population lives in cities, but by 2050, this is expected to rise
to nearly 70 percent. At the same time, demand for urban water is likely to double.
"The expansion of cities often takes place without proper land use planning and the resulting human pressure has highly damaging effects on natural and agricultural landscapes in and around urban
areas," said Mitsugi. By better factoring in forest solutions in urban planning, forests and green spaces can address a range of challenges.
They can remove harmful pollutants, reduce noise, improve temperatures, mitigate impacts of climate change, supply a range of products and renewable energy, protect water sources, and prevent
soil erosion and floods. For example, trees can reduce air conditioning needs by 30 percent if properly placed around buildings. In cold climates, they can shield homes from the wind and save energy used for heating
by 20-50 percent. A mature tree can absorb up to 150 kg of CO2 per year, and thus help mitigate climate change. Green areas can also have a positive effect on people's health and well-being, and can help create more cohesive societies. How to create greener cities? The forum's organisers launched a
call for action, putting forward a set of forest solutions for participants to endorse. These include:
