“…In addition, the increased size of greenspace patches may further contribute to the decrease of land surface temperature (Zhou et al, 2011aLi et al, 2012). Consequently, local residents suffer less from diseases caused by high temperature (Kenney et al, 2014;Sun et al, 2014), and may also consume less energy to maintain a comfortable indoor temperature. The increase in greenspace and change in spatial configuration may also have significant impacts on urban biodiversity (Kong et al, 2010), stream biotic conditions (Shandas and Alberti, 2009), and air quality (Nowak et al, 2006;Nowak et al, 2014).…”

a b s t r a c tUrban greenspace plays an essential role in urban ecosystem and highly contributes to the welfare of urban residents. Understanding the dynamics of greenspace is crucial for its planning and management. Previous studies have largely focused on changes in greenspace in urbanizing regions, using medium resolution remotely sensed data. However, the changes of greenspace in urbanized areas need to be accurately quantified based on high spatial resolution images because they are directly related to human health and well-being. This paper aims to enhance the understanding on dynamics of greenspace within well-developed areas of the city, using Beijing City, China as a case study. Using high spatial resolution remotely sensed imagery, we analyzed the spatial pattern of greenspace and its change on two scales: (1) the entire area within the 5th ring road, and (2) in 4 belts from urban center to fringe. We found urban greenspace was very dynamic. The proportion of urban greenspace increased by 5.45%, or 36.3 km 2 in size from 2005 to 2009. The amounts of gain and loss of greenspace were 69 km 2 and 32.7 km 2 , respectively, or 10.36% and 4.91% of the entire study area. Because of the very limited lands for greening in urbanized areas, the new patches of greenspace were generally small, with the mean patch size of 676.31 m 2 . However, those small patches enhanced the connectivity and continuity of urban greenspace. In addition, we found the differences in configuration of greenspace patches across the 4 belts were greater than the differences in total percent cover, indicating that compared to percent coverage, greenspace configuration may be more influenced by the development age.

“…Europe, especially Russia, also experienced an extremely hot summer accompanied by strong heat extremes in 2010 [4]. In East Asia, there was a total of more than 3000 deaths in South Korea because of a record-breaking heat extreme that occurred in 1994 [5], while a number of fatal heat extremes in 1998 [6], 2003 [6,7], and 2013 [8] had exceedingly adverse effects on several regions in China. With increasing global warming, heat extremes have tended to increase in their intensity and frequency [9,10].…”

Spatial Characteristics of Heat Extremes in South Korea from the Climatological Mean Perspective

We investigated the spatial characteristics of heat extremes in South Korea from the climatological mean perspective. A heat extreme was defined as a day when the daily maximum temperature was higher than 33 °C. According to our analyses, the eastern area of the Sobaek and Taebaek mountain ranges (hereafter called the eastern district) is significantly more exposed to heat extremes compared to other areas. The onset date and total number of days of annual heat extremes in the eastern district are approximately 13 days earlier and 3 days higher than those in the western district on average, respectively. Likewise, the annual mean of daily maximum temperatures during heat extreme days are approximately 0.25 °C higher. This larger exposure to heat extremes in the eastern district appears to be attributable to the Föhn phenomenon, which is likely induced by the dominant southwesterly monsoon during the early-to-peak summer. In contrast, differences in the ending dates of annual heat extremes are not noticeable between the eastern and western districts, when the southerly winds are dominant. Our analyses suggest that heat extremes in South Korea cannot be understood by a simple function of latitude, but in conjunction with atmospheric physical processes.

“…Excess outdoor temperature in the summer has resulted in an increased mortality during heat waves, especially among vulnerable older persons, in Europe [1,2] and worldwide [3,4,5]. At present, there are few recommendations on how to help older people adapt to these challenging conditions [6].…”

Indoor temperature is relevant with regard to mortality and heat-related self-perceived health problems. The aim of this study was to describe the association between indoor temperature and physical performance in older adults. Eighty-one older adults (84% women, mean age 80.9 years, standard deviation 6.53) were visited every four weeks from May to October 2015 and additionally during two heat waves in July and August 2015. Indoor temperature, habitual gait speed, chair-rise performance and balance were assessed. Baseline assessment of gait speed was used to create two subgroups (lower versus higher gait speed) based on frailty criteria. The strongest effect of increasing temperature on habitual gait speed was observed in the subgroup of adults with higher gait speed (−0.087 m/s per increase of 10 °C; 95% confidence interval (CI): −0.136; −0.038). The strongest effects on timed chair-rise and balance performance were observed in the subgroup of adults with lower gait speed (2.03 s per increase of 10 °C (95% CI: 0.79; 3.28) and −3.92 s per increase of 10 °C (95% CI: −7.31; −0.52), respectively). Comparing results of physical performance in absentia of a heat wave and during a heat wave, habitual gait speed was negatively affected by heat in the total group and subgroup of adults with higher gait speed, chair-rise performance was negatively affected in all groups and balance was not affected. The study provides arguments for exercise interventions in general for older adults, because a better physical fitness might alleviate impediments of physical capacity and might provide resources for adequate adaptation in older adults during heat stress.
