DESCRIPTION:Nathalie Baumann\, Urban ecologist\, consultant\, lecturer and
  researcher | ZHAW School of Life Sciences and Facility Management\nThe TR
 ANSFORM Institute (HEIA-FR) invites Nathalie Baumann\, urban ecologist\, l
 eader of the Urban Ecosystem Design Group at the ZHAW School of Life Scien
 ces and Facility Management\, and co-author of the book "Végétalisation 
 biodiverse et biosolaire des toitures" (2018) for a talk at the Smart Livi
 ng Lab in Fribourg on 20 February from 11 am to 12 pm.\n\nGlobal warming i
 s an acquired fact. One of the main results of climate change is the fact 
 of increase of temperature – but not only: another important fact is the
  rapid decline of biodiversity worldwide\, increasing temperature of the o
 ceans and more intensive natural hazards.\nUp to 75% of urban zones of man
 y cities across the world are covered with permeable and warm absorptive (
 and highly reflective) surfaces (asphalt\, concrete). This means that 75% 
 of normal rains will not be absorbed in the soil\, ground waters and runof
 fs\, through drainage systems\, into the rivers. The lack of vegetation in
  urban zones means that the following important functions in the cycle of 
 water\, absorption and retention\, which are assured by the vegetation and
  open soils (and rooftop substrates) are missing.\nThe urban sprawl linked
  to population growth and other human connected activities such as the pro
 duction and transport of goods are the main causes of habitats fragmentati
 on and biodiversity loss. The conflict between people and wildness in urba
 n areas (e.g. allergies\, anxiety\, unawareness) limits the chance of spec
 ies survival in built environments where land price discourages investment
 s towards nature conservation in favor of more lucrative ones (e.g. housin
 g\, construction of shopping centers and other places for entertainment). 
 Moreover\, our cities are often characterized by the unequal access of the
  population to green spaces\, the distance of semi-natural areas from city
  centers\, but also the low amount and poor quality of green spaces of the
  peripheries and suburban areas\, often polluted or neglected.\nBy returni
 ng directly to the 75% of permeable surfaces in urban zones\, when the sam
 e surface is planted\, thanks to divers existing measures like: green roof
 s\, green facades\, parks\, trees etc. up to 90% of the rain is progressiv
 ely absorbed by the soil and will reduce flash flooding.\nAll these above 
 mentioned surfaces can provide\, if planned as nature-based-solutions (NBS
 )\, suitable habitats for animal and plant species – so let’s have a c
 loser look to this and discuss\, share and plan our cities now and in the 
 future: biodiverse greener and healthier.
