AI 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.
Article Abstract
Wetland ecosystems (WE) are considered the most productive ecosystems on the globe which provide a range of basic and critical ecosystem services (ES) to humans. However, WE are constantly being degraded because of a poor understanding of social benefits at a local level and the lack of recognition of economic values for ES at sub-national and national levels. This study aims to compare a peri-urban wetland with a riverine wetland from lower Gangetic plain, Eastern India, to identify the bundle of ES based on its perceived importance from multiple perspectives at a local level. Participatory research tools have been employed (i.e., key informant interviews, household survey, and field observation) for data collection. Based on rapid assessment of wetland ecosystem services (RAWES) approach, a priority ranking analysis was used to examine ES. A Mann-Whitney U test was performed to find out significant differences in RAWES approach between riverine and peri-urban wetlands. Multiple regression model (MRM) was also performed to explore the impact of socio-demographic factors towards the perception of WES. Results showed that (i) the utilizations of WES largely vary between riverine and peri-urban wetland; (ii) provisioning and regulating ES were attributed relatively higher importance by the people of riverine and peri-urban wetlands in comparison to other ES; (iii) as per RAWES approach, the ESI value for riverine wetland was higher (0.58) than the peri-urban wetland (0.44) indicating the higher importance and dependence on WES; and (iv) population growth, expansion of settlement, climate change, and agricultural expansion were attributed as significant drivers of WE change (particularly for urban wetland). This study suggests the much-needed policy interventions and future pathways of research for developing effective measures to ensure livelihood sustainability of the dependent communities and to sustain (active) the ecosystem health of riverine and peri-urban wetlands.

Opposing objective and subjective wellbeing outcomes within an environmentally vulnerable delta: a case study of Volta Delta, Ghana.

Article Synopsis
- - The study investigates the relationship between objective and subjective wellbeing, particularly in environments vulnerable to climate change, emphasizing the need for comprehensive research that considers both measures rather than just objective ones.
- - Using a combination of binary logistic regression and qualitative methods in Ghana's Volta Delta, the findings reveal distinct wellbeing outcomes linked to environmental conditions, such as drought in agricultural areas versus flooding in coastal zones.
- - The research suggests that differences in livelihood vulnerability and perceptions of wellbeing are key factors influencing how individuals experience and respond to their environmental contexts.

This study represents the pioneering effort in employing 16S rRNA-bacteria and 18S rRNA-microeukaryotes to construct the microbial community-based index of biotic integrity (MC-IBI) for assessing the ecological health of riverine ecosystems. The MC-IBI was developed, validated, and implemented using water samples from the Changle River watershed, encompassing both wet and dry seasons. A total of 205 metrics, containing microbial diversity, composition, pollution tolerance/sensitivity, and functional categories, were selected as candidates for evaluation.

Integrating TB screening into house-to-house polio vaccination campaigns.
Public Health Action
March 2023
WHO Awka Field Office, Anambra, Nigeria.
Setting: In July 2019, the Anambra State (south-east Nigeria) TB Control Programme implemented the integration of TB case-finding with the polio vaccination campaign with the support of the WHO.
Objective: To improve TB case-finding from communities leveraging already existing polio structures.
Design: Vaccination teams were trained to ask for symptoms of TB in each household and to document details of people presumed to have TB.

Article Synopsis
- Organochlorine pesticides (OCPs) were extensively used in India for pest control, leading to their detection in water and sediment samples from the Krishna River Basin (KRB).
- Diagnostic ratios indicated ongoing use of Lindane in rural and peri-urban areas, while urban sites showed new inputs of technical HCH, suggesting varied pesticide usage based on land type.
- The study found that river sediments act as a sink for OCPs, with DDT posing significant ecological risks to aquatic life, particularly affecting zooplankton and certain fish species.
