Brief communication: Radar images for monitoring informal urban settlements in vulnerable zones in Lima, Peru

Lima, Peru's capital, has about 9.6 million inhabitants and keeps attracting more residents searching for a better life. Many citizens, without access to housing subsidies, live in informal housing and shack settlements. A typical social phenomenon in Lima is the sudden illegal occupation of areas for urban settlements. When such areas are unsafe against natural hazards, it is important to relocate such a population to avoid significant future losses. In this communication, we present an application of Sentinel-1 synthetic aperture radar (SAR) images to map the extension of a recent occupation of an area with unfavorable soil conditions against earthquakes.

Predictors of COVID-19 Vaccine Confidence: Findings from Slums of Four Major Metro Cities of India

There are limited studies on COVID vaccine confidence at the household level in urban slums, which are at high risk of COVID-19 transmission due to overcrowding and poor living conditions. The objective was to understand the reasons influencing COVID-19 vaccine confidence, in terms of barriers and enablers faced by communities in urban slums and informal settlements in four major metro cities in India. A mixed method approach was adopted, where in field studies were conducted during April–May 2021. First, a survey of at least 50 subjects was conducted among residents of informal urban settlements who had not taken any dose of the COVID-19 vaccine in Mumbai, Bengaluru, Kolkata and Delhi; second, a short interview with five subjects who had taken at least one dose of the vaccine in each of the four cities to understand the factors that contributed to positive behaviour and, finally, an in-depth interview of at least 3 key informants in each city to ascertain the vaccination pattern in the communities. The reasons were grouped under contextual, individual/group and vaccine/vaccination specific issues. The most frequent reason (27.7%) was the uncertainty of getting the vaccine. The findings show the need for increasing effectiveness of awareness campaigns, accessibility and the convenience of vaccination, especially among vulnerable groups, to increase the uptake.

Systematic review of lay consultation in symptoms and illness experiences in informal urban settlements of low-income and middle-income countries

ObjectivesLay consultation is the process of discussing a symptom or an illness with lay social network members. This can have positive or negative consequences on health-seeking behaviours. Understanding how consultation with lay social networks works in informal urban settlements of low-income and middle-income countries (LMICs) is important to enable health and policy-makers to maximise its potential to aid healthcare delivery and minimise its negative impacts. This study explored the composition, content and consequences of lay consultation in informal urban settlements of LMICs.DesignMixed-method systematic review.Data sourcesSix key public health and social science databases, Google Scholar and reference lists of included studies were searched for potential articles.Eligibility criteriaPapers that described discussions with lay informal social network members during symptoms or illness experiences.Data analysis and synthesisQuality assessment was done using the Mixed Methods Appraisal Tool. Data were analysed and synthesised using a stepwise thematic synthesis approach involving two steps: identifying themes within individual studies and synthesising themes across studies.Results13 studies were included in the synthesis. Across the studies, three main categories of networks consulted during illness: kin, non-kin associates and significant community groups. Of these, kin networks were the most commonly consulted. The content of lay consultations were: asking for suggestions, negotiating care-seeking decisions, seeking resources and non-disclosure due to personal or social reasons. Lay consultations positively and negatively impacted access to formal healthcare and adherence to medical advice.ConclusionLay consultation is mainly sought from social networks in immediate environments in informal urban settlements of LMICs. Policy-makers and practitioners need to utilise these networks as mediators of healthcare-seeking behaviours.PROSPERO registration numberCRD42020205196.

Factors Influencing Choices for Early Marriage in Urban Informal Settlements of Bangladesh

This study explores factors that shape parents’ decisions as to whether or not to arrange an early marriage of a girl child in the context of urban informal settlements in Bangladesh. The article draws on data from a larger mixed methods study conducted in two informal urban settlements of Bangladesh, and the analysis was guided by the theory of social exchange. The study found the following factors leading to early marriage: endemic poverty, high dowry costs for older girls, parents’ lack of wider social networks, adolescents dropping out of school, crime and insecurity, love affairs between adolescents and community pressure. Collaboration between government and non-government programmes to improve education, implementation of supportive laws, and greater formal economic opportunities for residents, including adolescents, in urban informal settlements, are critical to prevent early marriage in these environments.
