“…DF transmission mainly depends on mosquito breeding activities. Meteorological factors, such as temperature, relative humidity and atmospheric pressure, could affect the breeding activities of mosquito vectors [1,12,18,23]. Increased temperature could stimulate the breeding activity of mosquito vectors; increased rainfall and relative humidity could increase mosquito breeding sites, and decreased atmospheric pressure could increase the contact probability of Aedes mosquitoes and people.…”

“…Referring to mosquito breeding and DF transmission, meteorological conditions [11,12] as well as human (demographic structure, population size) [13,14,15] and land-use factors (traffic, standing water) [16,17] have been identified as important factors affecting the transmission of DF disease. For example, mosquito breeding activities are affected by temperature: Aedes albopictus are most active in breeding activities when the temperature is between 26 °C and 30 °C, but the feeding activity of mosquitoes decreases and mortality increases when the temperature is lower than 15 °C or higher than 35 °C [12]. Rainfall and humidity are positively associated with the reproduction of Aedes at the initial life stage of Aedes mosquitoes [18].…”

Dengue fever is one of the most common vector-borne diseases in the world and is mainly affected by the interaction of meteorological, human and land-use factors. This study aims to identify the impact of meteorological, human and land-use factors on dengue fever cases, involving the interplay between multiple factors. The analyses identified the statistically significant determinants affecting the transmission of dengue fever, employing cross-correlation analysis and the geo-detector model. This study was conducted in Guangzhou, China, using the data of confirmed cases of dengue fever, daily meteorological records, population density distribution and land-use distribution. The findings highlighted that the dengue fever hotspots were mainly distributed in the old city center of Guangzhou and were significantly shaped by meteorological, land-use and human factors. Meteorological factors including minimum temperature, maximum temperature, atmospheric pressure and relative humidity were correlated with the transmission of dengue fever. Minimum temperature, maximum temperature and relative humidity presented a statistically significant positive correlation with dengue fever cases, while atmospheric pressure presented statistically significant negative correlation. Minimum temperature, maximum temperature, atmospheric pressure and humidity have lag effects on the transmission of dengue fever. The population, community age, subway network density, road network density and ponds presented a statistically significant positive correlation with the number of dengue fever cases, and the interaction among land-use and human factors could enhance dengue fever transmission. The ponds were the most important interaction factors, which might strengthen the influence of other factors on dengue fever transmission. Our findings have implications for pre-emptive dengue fever control.

Purpose Urban built-up has been increasing exponentially in the world. Urban population growth and migration are depleting the land resources and creating thermal discomfort. Cities all around the world are facing urban heat island effects and increased temperatures. This study aims to map land cover and formulate local climate zones for enhancing urban resilience against disaster and climate risks. Design/methodology/approach This study uses exploratory research to identify local climate zones for Lahore, Pakistan. Landsat 8 imagery was used to develop a land use land cover map. For mapping local climate zones, the standard World Urban and Access Portal Tool procedure was used. Findings Results have revealed that Lahore has grown exponentially. Compact low rise and open low rise were the two most common local climate zones prevalent in the city. In contrast, the outer regions of the city consisted of LCZ D (low plants) and LCZ F (bare soil). Practical implications This study highlights the need to consider local climate zones in future development plans and policies for ensuring sustainable, resilient and climate-friendly cities. Originality/value Local climate zone studies are missing in Pakistan. This study has empirically analyzed the ground situation of local climate zones for Lahore metropolitan city. This study will provide baseline support for future studies on urban heat island and climate change adaptation planning.

“…Studies of dengue seroprevalence in Lahore and other Pakistani cities have indicated that disease incidence correlates with lower income and higher density urban environments—in short, there is higher risk of disease for the urban poor (Mahmood et al. 2019; Qureshi et al. 2017; Raza et al.…”

“…While breeding occurs within quite different landscapes, epidemiological risks are nonetheless distributed unevenly with respect to class. Studies of dengue seroprevalence in Lahore and other Pakistani cities have indicated that disease incidence correlates with lower income and higher density urban environments-in short, there is higher risk of disease for the urban poor (Mahmood et al 2019;Qureshi et al 2017;Raza et al 2018). Urban scholars have examined the "splintered" spaces of the contemporary city, where infrastructural unevenness is juxtaposed with logics of privatised provision and secessionary spaces (Graham and Marvin 2001).…”

In 2011, an outbreak of dengue fever struck the most urbanised districts of Punjab. After an initially slow response, the Punjab Government set up a digital disease surveillance system which was soon hailed as a model for epidemic control and public health governance. Despite these successes, Aedes aegypti mosquitoes have continued to take advantage of the micro‐ecologies of Lahore’s urban landscape—in part because of the fragmented and uneven socio‐spatial dynamics of water access, storage, and use. This paper brings into conversation, and in tension, these different infrastructural dimensions of dengue, namely the celebrated system of vector surveillance and the fractured infrastructures of water, within a single frame of “epidemic infrastructures”. It conceptualises the long‐standing unevenness of Lahore’s water systems as “infrastructures of transmission” and techno‐managerial systems of control as “infrastructures of problematisation”. The paper uses the lens of heterogeneity to bring together different components of these systems and explore their intersecting effects. I show how the transmission of dengue paradoxically follows both the scarcity and abundance of water use in the city. Yet these socio‐ecological complexities are bypassed in the technical matrices to visualise, enumerate, and emplace vectors, which also provide the means to narrativise state successes. I argue that epidemic infrastructures work together to reinforce individualised responsibilities for infrastructural maintenance and urban health to residents and workers.
