This is caused primarily by the covering up of natural land by roads and buildings, which absorb heat during the daytime and re-release it at night. One countermeasure is therefore to attempt to reverse this by carrying out a process of greenification. This was discussed in an earlier paper. Besides greenification, though, there are other practical methods available. These include utilizing the wind paths along rivers ; making use of mountain and sea breezes and 'cool' islands ; "dry mist" (whereby fine droplets of water are released from a height of about four meters) ; and 'uchimizu' (the traditional activity during which water is splashed over a road in order to cool it) and the modern high-tech version in which chemicals are added to the road-making materials so as to retain water and thereby allow the cooling effect of evaporation to take place over a longer period of time. This paper considers the non-greenification options for mitigating the heat island effect. 中央大学総合政策学部 2014-03-28 eng departmental bulletin paper VoR https://chuo-u.repo.nii.ac.jp/records/6428 1341-7827 総合政策研究(CJPSCS) Chuo Journal of Policy Sciences and Cultural Studies (CJPSCS) 22 57 63 https://chuo-u.repo.nii.ac.jp/record/6428/files/1341_7827~22~57.pdf application/pdf 84.9 kB 2019-04-22
