Abstract Urbanisation is a complex global phenomenon driven by unorganised expansion, increased immigration, and population explosion. Changes in land cover are one of the most critical components for managing natural resources monitoring environmental impacts this context. In present study, hybrid classification approach was applied to Landsat data get insight into urbanisation Chandigarh capi...

Anthropogenic changes highly impact the world's biodiversity. An important human-driven change to natural environments is increasing urbanisation, which responsible for decreasing suitable habitats many wild species, including bees. In this study, we investigate if three levels of urbanisation (low, medium and high) affect body size, foraging efforts abundance sweat bee Agapostemon virescens. O...

The effects of urbanisation are increasingly pervasive across landscapes, and this has implications for animals the ecological functions they support. Differences in attributes assemblages between ecosystems means we cannot assume that different within same landscapes affected by trajectory or over spatial scales. We test whether how ecosystem type can modify responses to urbanisation, contrast...

It has been suggested that Perthes' disease is more prevalent in urban areas, and that the risk increases with deprivation. We present the findings of a preliminary analysis of Perthes' disease in Northern Ireland, which is shown to have one of the highest national annual rates of incidence in the world (11.6 per 100000). Of the 313 children diagnosed over a seven-year period, 311 were allocate...

Up to date urban mapping and population data are required by policy makers, economists and planners in the developing world, and particularly for cities in South Asia, Latin America and Africa, to enable informed decision making. For many of these regions (particularly in the tropics) the all-weather capability of spaceborne imaging radar could prove to be a reliable and systematic monitoring t...

Résumé. L’étude de l’évolution d’un système complexe spatialisé devient critique dans de nombreux domaines. Par exemple, pour comprendre l’influence de l’homme sur le ruissellement dans les entités spatiales et selon leurs types d’occupation du sol (culture, urbanisation, habitation...) de manière à permettre aux décideurs d’anticiper les politiques d’urbanisme et d’agriculture. Dans cette démo...

A brief history of air pollution Accounts of air pollution in the UK date back to the 13 century. Early occurrences resulted from rapid population growth, urbanisation and changes in fuel use – in particular the medieval switch from wood to coal, especially in brick kilns and domestic fireplaces. Coal combustion in industrial furnaces, boilers and, above all, in domestic fireplaces, was the mai...
