Background:Ample information is available on extreme heat associated mortality for few Indian cities, but scant literature is available on effect of temperature on spatial variability of all-cause mortality for coastal cities.Objective:To assess the effect of daily maximum temperature, relative humidity and heat index on spatial variability of all-cause mortality for summer months (March to May) from 2014 to 2015 for the urban population of Surat (coastal) city.Materials and Methods:Retrospective analysis of the all-cause mortality data with temperature and humidity was performed on a total of 9,237 deaths for 184 summer days (2014-2015). Climatic and all-cause mortality data were obtained through Tutiempo website and Surat Municipal Corporation respectively. Bivariate analysis performed through SPSS.Observations:Mean daily mortality was estimated at 50.2 ± 8.5 for the study period with a rise of 20% all-cause mortality at temperature ≥ 40°C and rise of 10% deaths per day during extreme danger level (HI: > 54°C) days. Spatial (Zone wise) analysis revealed rise of 61% all-cause mortality for Southeast and 30% for East zones at temperature ≥ 40°C.Conclusions:All-cause mortality increased on high summer temperature days. Presence of spatial variation in all-cause mortality provided the evidence for high risk zones. Findings may be helpful in designing the interventions at micro level.

Population growth drives the process of urbanization and associated landscape changes. The conversion of natural landscape to anthropogenic landscape represents the most visible and pervasive form of human impact on the environment. The impact of population growth on Bundelkhand Landscape, Central India was analyzed using Landsat series satellite and MODIS Terra products. Population growth (total, urban and rural), landscape changes and variability in land surface temperature were analyzed for the last decades. The population has been increased manifold since 1901 and urbanization has also increased with the rate of 1.4km 2 a -1 during last 24 years. This increase was rapid in current years (2000)(2001)(2002)(2003)(2004)(2005)(2006)(2007)(2008)(2009)(2010)(2011)(2012)(2013) as compared to previous years (1989 -2000). Due to rapid population growth, forest cover has been reduced by ~54% while agricultural land has been increased by ~76%. The mean land surface temperature has also increased by ~0.5 o C during last 14 years (2001)(2002)(2003)(2004)(2005)(2006)(2007)(2008)(2009)(2010)(2011)(2012)(2013)(2014). It is observed that the population growth was proportional to the growth of agriculture land (r = 0.91, p < 0.05, n = 4) and the built up area (r = 0.94, p < 0.05, n = 4) while inversely proportional to the forest resources (r = -0.99, p < 0.001, n = 4). The study indicates the phenomena "human environment interaction" where rapid population growth has lead LULC changes. This study also reveals that population growth is imposing an increasing burden on the limited and continually degrading natural resources thus altering the local environment.

In developing countries like China, urbanization is still occurring at a rapid pace. During urbanization, the urban land expands drastically, which makes suburbs the most affected area facing urban expansion. The land transition has proven to threaten the function and security of ecosystems, and therefore the topics of suburban land transition and ecological security have raised much attention. However, the urban-suburban interaction, which is one of the basic characteristics of suburbs, has been insufficiently considered. The urban-suburban interaction is developed based on the flows of people, materials, and information between urban and suburban areas, and it essentially reveals the relationship between human activities and land-use optimization. To fill the research gap, this study adopts a case study of Wuhan city, and first quantifies the urban-suburban interactions from a symbiotic perspective, and investigates rural residents and public buses to verify the estimated interactions. The results show that there is obvious heterogeneity in urban-suburban interactions in different suburban towns. Correlation analysis and geographic weight regression are then applied to demonstrate the relationship between the urban-suburban interaction and urbanization in the suburbs. Additionally, urbanization potential in the suburbs is estimated. Then, a suburban ecological security assessment is conducted by a "pressure-status-response" (PSR) model, and the urbanization potential that is estimated based on urban-suburban interaction is integrated as a "pressure" indicator. The comparison between the suburban ecological security assessment results based on considering and not considering urban-suburban interaction demonstrates the importance of considering urban-suburban interaction. This study contributes to the understanding of the complicated relationships of urban-suburban socio-economic, spatial, and ecological environments, and offers suggestions for suburban planning and ecological protection.Sustainability 2020, 12, 1600 2 of 22 and ecological threat [2][3][4][5]. Hence, studies on urban-suburban interaction have caught much attention in recent years.Despite the existing studies on urban-suburban interaction analysis, the effects of such interactions on land transition and the eco-environment are insufficiently discussed. Land transition is one of the biggest challenges that the suburbs face in both developing and developed countries. In developing countries, urbanization is occurring at a rapid pace and is accompanied by fast urban land expansion. During this process, a large amount of ecological land transits into the urban area, including natural land and cropland [6][7][8]. Developed countries also confront similar problems. For example, Salvati, et al. [9] concluded that the urban expansion in discontinuous and low-density Mediterranean regions threatens soil quality and vulnerable ecologies. Ustaoglu and Williams [10] pointed out that there is a significant land conversion from agricultural land to urban land i...
