Urban novel ecosystems were sampled across vacant sites in two Portuguese urban regions. The flora studied with a focus on species’ origin, life form, ecological, chorological and naturalisation types. A multivariate constrained ordination technique was used to identify relationships between plant composition environmental factors. vegetation of the regions shows differences, highlighting biome...

Arid regions are an important part of the world as they cover more than 40% of the land surface and they can provide sufficient opportunities for extensive development. However, urban development of these regions is facing a set of problems. This is besides the development barriers due to the arid regions climate associated with a set of economical, social, administrative, and physical problems...

land use is often referred as the basis for urban planning. perhaps the main reason is that the discussion of fundamental related to urban planning objectives has play the first role in the land use studies. basic topics such as proper location, optimal allocation, diversification, functionality and … which are in direct contact with comfort goals, are the last objectives of urban planners and ...

The quality of life for people in urban regions can be improved by predicting urban human mobility and adjusting urban planning accordingly. In this study, we compared several possible variables to verify whether a gravity model (a human mobility prediction model borrowed from Newtonian mechanics) worked as well in inner-city regions as it did in intra-city regions. We reviewed the resident pop...

Data about points of interest (POI) have been widely used in 7 studying urban land use types and for sensing human behaviors. However, it 8 is difficult to quantify the right mix or the spatial relations among different 9 POI types indicative of specific urban functions. In this research, we develop a 10 statistical framework to help discover semantically meaningful topics and func11 tional reg...
