Nighttime light (NTL) is a reliable indicator for measuring urban development, population density, and economic activities. This study sets out to explain the spatio-temporal pattern of urbanization and population distribution using pixel-based NTL data. Changes in NTL intensity in Puglia (Italy) were evaluated from 2014 to 2023, and how NTL is affected by various spatial metrics was investigated. Summer–winter differences at the pixel level were monitored utilizing the Normalized Nighttime Light Index (NNLI), and the relationship between this indicator and tourism was assessed. A consistent increase in NTL across the region in both summer and winter was measured, with variations among provinces. Urban areas with high population density showed greater NTL values, while inland areas showed low NTL intensity. The study also revealed that proximity to urban areas was the most influential factor in predicting NTL intensity. The analysis revealed that differences between summer and winter correlated with tourist activity, especially in coastal municipalities. Leveraging NTL images can support decision-making across various sectors and aid in developing evidence-based urban strategies tailored to local needs and challenges.

Limited research has explored associations between blue spaces and mental health, specifically in children. This study assessed links between coastal proximity and depression and anxiety among children in Australia and tested whether duration of residency at current address moderated associations. It also explored associations between within‐individual changes in coastal proximity and changes in depression and anxiety. Data were from 2400 children aged 11–12 years in Wave 5 (2012) and aged 14–15 years in Wave 6 (2014) of the national Longitudinal Study of Australian Children. Outcomes were children's self‐reported symptoms of depression and anxiety. Exposure was coastal proximity (<2, 2–<5, 5–<10, 10–<20, 20–<50, and ≥50 km). Linear models were fitted to examine cross‐sectional associations and fixed effects models for within‐individual associations. After adjustment for potential confounders, findings suggested that those living close to the coast (<2 km) had lower levels of depression than those living the furthest from the coast (≥50 km) during childhood (Wave 5) but not adolescence (Wave 6). No associations were observed with anxiety. There was weak evidence to suggest residency duration moderated associations. No associations were observed for within‐individual changes. Further research is needed to understand whether and what characteristics of coastal environments may benefit children's mental health. This study assessed links between coastal proximity and depression and anxiety among children in Australia. Findings suggested those living close to the coast (<2km) had lower levels of depression than those living the furthest from the coast (≥50km) during childhood (11–12 years old) but not adolescence (14–15 years old).

We investigate georeferenced household‐level data consisting of up to 128,609 individuals living in 11,261 localities across 17 coastal sub‐Saharan African countries over 20 years. We analyze the relevance of coastal proximity, measured by the geographic distance to harbors, as a predictor of individual economic living standards. Our setting allows us to account for country‐time fixed effects as well as individual‐specific controls. Results reveal that individuals living further away from the coast are significantly poorer, measured along an array of welfare indicators. Our findings are robust to the inclusion of other geographic covariates of development such as climate (e.g., temperature, precipitation) or terrain conditions (e.g., ruggedness, land suitability). We also explore mechanisms through which coastal proximity may matter for individual welfare and decompose the estimated effect of coastal proximity via formal mediation analysis. Our results highlight the role of human capital, urbanization, and infrastructural endowments in explaining within‐country differences in individual economic welfare. [ABSTRACT FROM AUTHOR]

Background Recent findings suggest that individuals living near the coast are healthier than those living inland. Here we investigated whether this may be related to higher levels of physical activity among coastal dwellers in England, arising in part as a result of more visits to outdoor coastal settings. Method Participants (n = 183,755) were drawn from Natural England's Monitor of Engagement with the Natural Environment Survey (2009-2012). Analyses were based on self-reported physical activity for leisure and transport. Results A small, but significant coastal proximity gradient was seen for the likelihood of achieving recommended guidelines of physical activity a week after adjusting for relevant area and individual level controls. This effect was statistically mediated by the likelihood of having visited the coast in the last seven days. Stratification by region, however, suggested that while the main effect was relatively strong for west coast regions, it was not significant for those in the east. Conclusions In general, our findings replicate and extend work from Australia and New Zealand. Further work is needed to explain the marked regional differences in the relationship between coastal proximity and physical activity in England to better understand the coast's potential role as a public health resource.

Supplemental irrigation can be a viable means of increasing lowbush blueberry (Vaccinium angustifolium) crop yields in humid environments. To best utilize this management technique, Maine growers require accurate knowledge of regional crop water demands. Meteorological data and weighing lysimeters were used to determine Penman-Montieth grass reference evapotranspiration (ETo) rates and actual evapotranspiration rates of the lowbush blueberry at five irrigated and two nonirrigated fields of varying distance from the Maine coast. Mean daily values of air temperature, relative humidity range, and solar flux were all found to increase with increasing distance from the coast. The frequency of growing season fog hours increased from 3.7% of all hours at a distance of 22.5 km from the coast, to 11.1% of all hours at a distance of 0.8 km from the coast. Water equivalent inputs from fog per growing season at these two sites averaged 7.2 cm and 18.3 cm, respectively. These geographic climatic differences were reflected in the calculated evapotranspirationo rates, which also generally increased with distance from the coast. Four-year mean weekly ETo rates for July, the month of greatest potential water demand, were 2.76 cm/week, 3.21 cm/week, 3.52 cm/week, and 4.23 cm/week for sites located 0.8 km, 6.4 km, 22.5 km, and 48 km, respectively, from the coast. Actual ET rates for both crop and prune rotations followed a similar pattern of increasing magnitude with distance from the coast. For July, mean crop and prune year pooled weekly ET rates at 0.8 km, 6.4 km, and 22.5 km from the coast were: 1.69 cm/week (0.85), 2.28 cm/week (0.73), and 2.40 cm/week (0.83), respectively. Standard condition crop coefficient (Kc) values for both rotations during the months of May through September were calculated to be 0.68 for sites 6.4 and 22.5 km from the coast. Thus, it would appear that the same Kc value can be used universally within the typical growing range of the Maine lowbush blueberry. These findings should substantially contribute to improved water use efficiency for the irrigated lowbush blueberry in Maine. [ABSTRACT FROM AUTHOR]

Consideration of spatial distance friction is important for ensuring that marine services and productivity are not misused. Based on data from Chinese seafood restaurants, this study constructed a distance decay model to identify the spatial trends and changes in seafood availability at different geographical distances. The results show that the distribution of seafood restaurants from coastal to inland areas has the characteristics of a core periphery circle structure, with the core concentration area, the diffusion area, and the boundary of seafood availability being 50–350 km, 350–1200 km, and more than 1200 km, respectively, from the coastline to inland. Additionally, we found that seafood availability has the characteristics of distance decay, with the best distance decay function to identify the number and density distributions of restaurants being the square exponential and exponential models (their spatial friction coefficients are −3.450e-7 and -0.002, respectively). In the pure distance model, coastal proximity and distance decay jointly restrict the geographical scope of seafood availability. Coastal proximity leads to the rapid decay of seafood restaurant distribution, and distance decay makes the distribution of seafood restaurants more centralized. Our research can provide some reference for solving the scalar dilemma of fisheries, fishery management, and spatial planning. [ABSTRACT FROM AUTHOR]

The article presents a study on the climatological temperature and precipitation in the U.S. It uses the Parameter-elevation Relationships on Independent Slopes Model (PRISM) interpolation method to develop data sets that reflected and the current states of knowledge of spatial climate patterns in the country. PRISM interpolation uncertainties were estimated with cross-validation mean absolute error and the 70 percent prediction interval of the climate-elevation regression function. It demonstrates that using a relatively dense station data set ad the physiographically sensitive PRISM interpolation process resulted in improved climate grids over those of WorldClim and Daymet.

Almost half a century has passed since Jean Gottmann coined the term “Megalopolis” in reference to the almost continuously urbanized stretch of land spanning the East Coast of the United States from southern New Hampshire to northern Virginia. Because a disproportionate concentration of population resided in this Megalopolis, the northeastern core enjoyed an economic and cultural supremacy, and he termed the Megalopolis “The Main Street of the Nation.” By the later 1960s and 1970s, however, population migration patterns began to reflect the influence exerted by the emergence of a second national core centered on the large metropolitan areas along the Pacific Coast, especially those of the Los Angeles and Bay Area conurbations in California. Although of different character, this burgeoning concentration of population, economic activity, and cultural influence may reflect the development of a West Coast Megalopolis that could soon rival the original Megalopolis of the Northeastern Corridor. Today, the U.S. population distribution is largely a bicoastal one. This article documents the emergence of this bicoastal population distribution. Using historical census data and GIS technology, we present a number of novel ways to graphically portray and examine this population redistribution phenomenon. The United States is not unique in witnessing an increasing share of its inhabitants clustering in coastal zones. Current critical policy concerns about the worldwide vulnerability of coastal populations have focused the need for better coastal population estimates and better mapping methods for portraying population redistribution trends.
