Proper knowledge regarding the spatial dependence of ecosystem service values (ESVs) on the changes in land use dynamics is essential for environmental management as well as sustainable urban development. To investigate this complex association concerning a fast-growing secondary city, this study estimated the integrated land use dynamic degree (IL...

Urban heat island (UHI) related heat stress and its association with human comfort were mainly conducted mainly in the temperate developed countries. Lack of researches in underdeveloped and developing countries has somehow created a gap in advancing the knowledge on UHI-related issues. Further, it is well acknowledged that the issue of human comfo...

In evaluating the integrated remote sensing-based ecological index (RSEIPCA), principal component analysis (PCA) has been extensively utilized. However, the conventional PCA-based RSEI (RSEIPCA) cannot accurately evaluate component indicators’ spatially shifting relative significance. This study presented a novel RSEI evaluation strategy based on g...

Several cities in the world have been subjected to urban sprawl. For instance, in India, this process is responsible for environmental degradation. The case of Siliguri Municipal Corporation (SMC) is a good example. Therefore, a proper investigation of the urban expansion characteristics of SMC is required to provide a basis for sustainable urban e...

Rapid urbanization urges the immediate attention of policymakers to ensure sustainable city development. Understanding the urban growth drivers is essential to address effective strategies for urbanization-related challenges. This work aims to study Raiganj’s urban development and the factors associated with this expansion. This study employed glob...

A few recent studies revealed that the intensity of UHI is increasing in medium-class cities due to the rapid degradation of natural vegetation covers. This study explores the patch-level association between green space and LST on a spatial-temporal basis to reflect how green space concentration can influence the LST intensity. A total of 12 landsc...

Drainage modification alters the natural drainage condition of the river and the surrounding region. After the devastating flood in 2003, the irrigation department of West Bengal has constructed a permanent embankment at the junction of the Pagla and the Ganga River. As a result, Pagla River became separate permanently from the Ganga River and this...

India ranks over 100 in the Human Development Index (HDI). However, Kerala, a small coastal state of south India, has a high HDI and is commonly referred to as the master of social development. This paper analyses the nature of human development in the villages of Kerala to reveal the spatial pattern of human development at the local level. HDI is...

Improvement of a city's liveability, especially in developing countries, is increasingly viewed as a way to enhance city dwellers' quality of life. This study applied remote sensing and GIS-based techniques to assess urban livability conditions based on the World Health Organization guidelines. For this, 21 fine-grained spatial indicators were sele...

In recent times, the role of secondary cities is growing rapidly. It is observed that secondary cities in Latin America contribute nearly 25% of the country's GDP. Rapid urbanization in secondary cities is also noticed in developing South Asian countries. However, the investigations on the theme of urbanization and its associated facts largely rema...

The first incident of COVID-19 case in India was recorded on 30th January, 2020 which turns to 100,000 marks on May 19th and by June 3rd it was over 200,000 active cases and 5,800 deaths. Geographic Information System (GIS) based spatial models can be helpful for better understanding different factors that have triggered COVID-19 spread at district...

The existing model of urban development is found responsible for growing environmental problems in the cities. This is due to the greater focus on the economic development at the cost of the environment. As a result, it led to some serious problems like air, water, soil pollution in the cities. It urged for a better ecologically based urban plannin...

The loss of peri-urban wetlands is a major side effect of urbanization in India in recent days. Timely and proper assessment of wetland area change is essential for the conservation of wetlands. This study follows the integrated way of the peri-urban wetland degradation assessment in the case of medium and small-size urban agglomerations with a spe...

The emergence of COVID-19 has brought a serious global public health threats especially for most of the cities across the world even in India more than 50 % of the total cases were reported from large ten cities. Kolkata Megacity became one of the major COVID-19 hotspot cities in India. Living environment deprivation is one of the significant risk...

Application of importance-performance analysis (IPA) has received wide applicability to reveal resident’s satisfaction with the performance of ecological services. In recent days, researchers have expanded the horizon of IPA through the implication of this technique in case of different ecosystem services to find out the satisfaction of local peopl...

India is a large country with several axes of inequality. Among the various axes of inequality, the regional disparity is the prominent one. This study aims to find out the most backward districts in India with the help of the latest available statistics data. For this purpose, 25 indicators are selected and these are further categorized into six d...

Deprivation of socio-economic well-being is one of the major reasons behind the occurrence of regional disparity in India. The present study has attempted to present and compare the regional pattern of deprivation in rural India by formulating a simple summary index of multidimensional deprivation (IMD) at the district level using global principal...

The reason behind the landslides in Darjeeling Himalaya varies from place to place. Seepage of rainwater through fragile lithological structure initiates shallow landslides, while modification of slope due to unscientific anthropogenic activities led to the occurrence of deep-seated landslides. Besides this, this region does not possess any proper...

Landslide susceptibility map provides a useful tool to the decision-makers to prevent and mitigate landslide hazards. For this study 16 spatial parameters and past landslide inventory have been taken into consideration and these are categorized under six factors clusters. For providing relative importance to the parameters modified analytic hierarc...

Objectives Socioeconomic inequalities may affect COVID-19 incidence. The goal of the research was to explore the association between deprivation of socioeconomic status (SES) and spatial patterns of COVID-19 incidence in Chennai megacity for unfolding the disease epidemiology. Study design Ecological (or contextual) study for electoral wards (sub-...

Darjeeling Himalaya is one of the several mountainous areas of India which is often suffered from landslide hazards. In this paper, a multi criteria evaluation is applied using 16 morphometric indicators, geology and lineaments to identify the areas vulnerable in respect to drainage and relief conditions. As both drainage and relief parameters exer...

The present paper intends to delineate flood plain wetland in Tangon river basin (1988–2016) from Landsat images and to investigate the nature and causes behind squeezing wetland and losses. From the analysis it is found that the total recognized average wetland area in pre monsoon season and post monsoon season are respectively 13.37 and 67.05 km²...

Landslide is a major threat in the Darjeeling Himalaya within sub-humid climate. Hence proper identification of landslide susceptible zone (LSZ) is very much essential. In this case a multi criterion evaluation approach is applied using thirteen selected indicators. The parameters are categorized into five categories viz. anthropogenic factor, surf...

The occurrence of landslide in the hilly region of Darjeeling during monsoon season is a matter of serious concern. Every year this natural hazard damages the major roads at several places and thus disrupts the transport and communication system in this region. This paper tries to prepare a landslide susceptibility zone (LSZ) map for the Gish River...
