The Degree of Urbanisation is a new definition cities, towns and semi-dense areas, rural areas endorsed by the UN Statistical Commission. urban population share according to similar one based on national definitions in Americas, Europe Oceania, but considerably higher Africa Asia. An empirical analysis comparison concepts suggest that are likely be classified as Asia other parts world. paper shows cities cover only small land, this doubled over past forty years, has number cities. Although...
Available statistics on tourism from official European sources are limited in terms of both the spatial and temporal resolutions, curbing potential analyses applications relevant for management policy. In this study, we produced a novel, complete consistent dataset describing tourist density at high resolution with monthly breakdown whole Union. This is achieved thanks to integration data conventional statistical big emerging sources, namely two major online booking services containing...
In the last few decades magnitude and impacts of planetary urban transformations have become increasingly evident to scientists policymakers. The ability understand these processes remained limited in terms territorial scope comparative capacity for a long time: data availability harmonization were among main constraints. Contemporary technological assets, such as remote sensing machine learning, allow analyzing global changes settlement process with unprecedented detail. Global Human...
The growth of the built environment is a global environmental change processes that can be measured and monitored with Earth Observation. That expected to continue as populations both increase urbanize. Global Human Settlement Layer (GHSL) project was set up measure monitor its changes [1]. GHSL layers presented herein are derived by processing archive Landsat imagery dating back 1975. from include four information corresponding epochs: 1975, 1990, 2000 2014 [2]. geo-information generated...
Better and more detailed analyses of global human exposure to hazards associated disaster risk require improved geoinformation on population distribution densities. In particular, issues temporal spatial resolution are important for determining the capacity assessing changes in these distributions. We combine best-available grids with latest data volcanoes, assess characterize worldwide from 1975–2015 relation recent volcanism. Both Holocene volcanoes those where there is evidence...
Sustainable Development Goal (SDG) 11 aspires to “Make cities and human settlements inclusive, safe, resilient sustainable”, the introduction of an explicit urban goal testifies importance urbanisation. The understanding process urbanisation capacity monitor SDGs require a wealth open, reliable, locally yet globally comparable data, fully-fledged data revolution. In this framework, European Commission–Joint Research Centre has developed suite (open free) tools named Global Human Settlement...
The application of last-generation spatial data modelling, integrating Earth Observation, population, economic and other spatially explicit data, enables insights into the sustainability global urbanisation processes with unprecedented detail, consistency, international comparability. In this study, land use efficiency indicator, as developed in Sustainable Development Goals, is assessed globally for first time at level Functional Urban Areas (FUAs). Each FUA includes city its commuting zone...
The Global Human Settlement Layer (GHSL) project fosters an enhanced, public understanding of the human presence on Earth. A decade after its inception in Digital Earth 2020 vision, GHSL is established European Commission's Joint Research Centre and integral part Copernicus Emergency Management Service. 2023 edition, a result rigorous research Observation data population censuses, contributes significantly to worldwide settlements. It introduces new elements like 10-m-resolution, sub-pixel...
Abstract. Disaster risk is not fully characterized without taking into account vulnerability and population exposure. Assessment of earthquake in urban areas would benefit from considering the variation distribution at more detailed spatial temporal scales, a explicit integration this improved demographic data with existing seismic hazard maps. In present work, "intelligent" dasymetric mapping used to model dynamics high resolution order analysis spatio-temporal exposure metropolitan area....
Data on global population distribution are a strategic resource currently in high demand an age of new Development Agendas that call for universal inclusiveness people. However, quality, detail, and census data varies significantly by country suffers from shortcomings propagate to derived grids their applications. In this work, the improved capabilities recent remote sensing-derived settlement detect mitigate major discrepancies with is explored. Open layers mapping built-up presence were...
The presence of green spaces within city centres has been recognized as a valuable component the landscape. Vegetation provides variety benefits including energy saving, improved air quality, reduced noise pollution, decreased ambient temperature and psychological restoration. Evidence also shows that amount vegetation, known ‘greenness’, in densely populated areas, can be an indicator relative wealth neighbourhood. ‘grey-green divide’, contrast between built-up areas with dominant grey...
Exposure is reported to be the biggest determinant of disaster risk, it continuously growing and by monitoring understanding its variations over time possible address risk reduction, also at global level. This work uses Earth observation image archives derive information on human settlements that are used quantify exposure five natural hazards. paper first summarizes procedure within settlement layer (GHSL) project extract built-up area from 40 year deep Landsat archive population density...
Abstract The knowledge of the spatial and temporal distribution human population is vital for study cities, disaster risk management or planning infrastructure. However, information on often based place-of-residence statistics from official sources, thus ignoring changing densities resulting mobility. Existing assessments spatio-temporal are limited in their detail geographical coverage, promising mobile-phone records hindered by issues concerning availability consistency. Here, we present a...
Human settlements typically expand to accommodate additional housing demand from a growing population and their socio-economic activities. This implies consumption of land, limited resource necessary for many other services. The efficiency this exploitation in relation demographic trends is key preserve land natural capital that could otherwise be degraded. Here, we assess patterns built-up area growth over the period 2000–2015, using statistics remote-sensing data. We find on average, EU27,...
Monitoring sustainable urban development requires comparable geospatial information on cities across several thematic domains. Here we present the first global database combining such with city extents. The Global Human Settlement Urban Centre Database (GHS-UCDB) is produced by data integration to characterise more than 10,000 centres worldwide. multi-dimensional and multi-temporal, containing 28 variables five domains having multitemporal attributes for one or epochs when UC are delineated...
Available global population grids suffer from limitations that constrain their usability. The Global Human Settlement Layer (GHSL) may benefit disaggregation and mapping. We test the integration of GHSL built-up grid Gridded Population World (GPW) in order to refine mapping distribution Syria, for year 2000, greatly improving depiction density. Preliminary results indicate is a good proxy disaggregation.
