Urban expansion is a global phenomenon that impacts biodiversity loss and climate change. Soil sealing increases land degradation and the ecosystem services supply. This degradation also negatively affects ecosystem health, essential to make cities more sustainable and liveable.

Urban green space (UGS) provides multiple cultural ecosystem services (CES) and enhances people's physical and mental well-being. The importance of UGS was more critical during crisis periods such as the COVID-19 pandemic. Recently, UGS has been under severe threats due to rapid urban expansion and climate change.

Mountains are one of the most ecological functional areas and provide wide range of ecosystem services (ESs) to the adjoining people. However, the mountainous ESs are highly vulnerable due to land use and land cover (LULC) change and climate change. Therefore, evaluations of the nexus between ESs and mountainous communities are essentially required for policy purpose.

Burdwan City experienced an important urbanization trend inducing dramatic land use/land cover (LULC) changes over the past 28 years. However, their effects on ecosystem services value (ESV) remain unknown. The prime objective of this study is to analyze the spatial heterogeneity of ESV in the Burdwan Planning Area (BPA) from 1990 to 2018.

Rapid urbanisation and climate change have emerged as serious threats to ecosystem services (ES), and the deterioration of ES is affecting the quality of life. The research on ES was long performed from monetary perspectives and neglected evaluation of ES from social perspectives. This study proposes a social appraisal approach for evaluating urban river ES on Mahananda River in English Bazar Urban Agglomeration (EBUA), Eastern India, through the social perception and preference (SPP) approach.

The diurnal and seasonal variation of PM, SO, NO, NH and water-soluble compounds were studied in Naraina industrial area; Delhi from January to December, 2017. It was observed that annual average concentrations of PM SO, NO, NH SO, NO, NH,Na, K, Ca, Mg, Cl and F in the day time were 227 ± 91, 9 ± 5, 59 ± 22, 65 ± 15, 17.45 ± 5.

Air pollution in India during COVID-19 lockdown, which imposed on 25th March to 31st May 2020, has brought a significant improvement in air quality. The present paper mainly focuses on the scenario of air pollution level (PM, PM, SO, NO and O) across 57 urban agglomerations (UAs) of India during lockdown. For analysis, India has been divided into six regions - Northern, Western, Central, Southern, Eastern and North-Eastern.

Article Synopsis
  • - Wetland ecosystems (WE) provide essential services to humans but are threatened by a lack of understanding of their local social benefits and economic values, particularly in Eastern India’s lower Gangetic plain.
  • - The study compared a peri-urban wetland to a riverine wetland to assess ecosystem services (ES) using participatory methods, revealing significant differences in their utilization and highlighting the greater importance placed on provisioning and regulating ES.
  • - Findings indicated that riverine wetlands have a higher ecosystem service importance index (ESI) value than peri-urban wetlands, with factors like population growth and climate change impacting wetland health, prompting the need for policy intervention for sustainable livelihoods and ecosystem preservation.

The flows of ecosystem services (ESs) from ecological patches (EPs) are being severely challenged due to global change. However, the evaluation of nexus between tribal society and ecological units with focus of tribal livelihood was not a subject of enquiry until recent past. Present study hypothesized that the different EPs has differential nexus in terms of delivery of ESs in Barind region, Eastern India.

Present study aims to examine the impact of lockdown on spatio-temporal concentration of PM and PM categorized and recorded based on its levels during pre-lockdown, lockdown and unlock phases while noting the relationship of these levels with meteorological parameters (temperature, wind speed, relative humidity, rainfall, pressure, sun hour and cloud cover) in Delhi. To aid the study, a comparison was made with the last two years (2018 to 2019), covering the same periods of pre-lockdown, lockdown and unlock phases of 2020. Correlation analysis, linear regression (LR) was used to examine the impact of meteorological parameters on particulate matter (PM) concentrations in Delhi, India.

UN-Habitat identified the present COVID-19 pandemic as 'city-centric'. In India, more than 50% of the total cases were documented in megacities and million-plus cities. The slums of cities are the most vulnerable due to its unhygienic environment and high population density that requires an urgent implementation of public healthcare measures.

The well-being of the human society cannot be ensured and sustainable unless the flow of Ecosystem Services (ESs) would be matching with their consistent demand. The consistent flow of ESs required sustainable management of ecological resources of the ecosystem. The management of ecosystem can be ensured with variety of approaches.
