In this research, the authors propose a supervised machine learning approach, Random Forest, for population density appraisal in a large and dense developing city.
Using survey data were collected from 657 married women between April and July 2018, the study investigates whether fertility decline was significantly higher in neighborhoods containing known Zika cases, compared to unexposed neighborhoods in the city state of Singapore.
The paper explores the impacts of climate and disaster-induced relocations on communities living on, or neighbouring, relocation site land in two countries, Fiji and the Philippines.
The authors use use a new high-resolution geospatial model to measure and map nitrogen (N) and pathogen—fecal indicator organisms (FIO)—inputs from human sewage for ~135,000 watersheds globally to assess the the potential impacts of human sewage on coastal ecosystems.
The article “looks back” to the origins of environmental demography, identifying pivotal agenda-setting moments in the 1990s and tracing the impact on contemporary research. Then, it also “looks forward” to identify critical gaps and challenges that remain to be addressed and to set an agenda for future research on population responses to environmental change.
This sequel to the Groundswell report includes projections and analysis of internal climate migration for three new regions: East Asia and the Pacific, North Africa, and Eastern Europe and Central Asia. Qualitative analyses of climate-related mobility in countries of the Mashreq and in Small Island Developing States (SIDS) are also provided. This new report builds on the scenario-based modeling approach of the previous Groundswell report from 2018, which covered Sub-Saharan Africa, South Asia, and Latin America.
Analysing qualitative data from interviews of residents' concerns about local coastal changes, the authors examine the experiences of residents in three low-lying villages across two small island states: Dreketi and Karoko in Fiji, and Funafala in Tuvalu.
Combining current and projected populations at settlement level with permafrost extent, this study presents the first estimates of the number of inhabitants on permafrost in the Arctic Circumpolar Permafrost Region (ACPR) and project changes as a result of permafrost thaw.
The authors assess the performance of four gridded population data sets from 2015 for the Dian-Gui-Qian region of Southwest China: Gridded Population of the World version 4 (GPW4), Global Human Settlement (GHS), LandScan, and WorldPop.
The authors examined associations between the sociodemographic composition of Gulf Coast census tracts and the density of petrochemical facilities that reported releases in the month following Hurricane Harvey by calculating a Hurricane Harvey petrochemical hazard density index (PHDI) based on the locations of 42 facilities with reported releases along the Texas Gulf Coast and using sociodemographic data from the American Community Survey to examine census tract-level social inequalities in PHDI (n = 1099 tracts).
