Water as a coolant of cities

Solcerova, A. (author)

Since more than half of the world population already lives in cities, it is important to understand the urban climate and its particularities. One of the typical aspects of urban areas is that cities are generally warmer than their rural surrounding. This phenomenon was first time described 200 years ago in the case of London and is commonly...

Regionalist principles to reduce the urban heat island effect

Echevarria Icaza, L. (author), van der Hoeven, F.D. (author)

Scientists, climatologists, and urban planners have started to recognize the importance of nature at two very different scales: the global (metabolic) and the local (liveability) scales. The regional scale is the one at which these macro and micro approaches overlap. Future predictions foresee an increase of more than 2450 million urban...
