“…LUCC is one of the main causes of global change, and it is the issues most closely related to natural and human processes, affecting the sustainable development of cities, societies and people's daily lives (Gao et al, 2015;Mottet et al, 2006). Economic and social factors were considered in the study of causes, mechanism, driving forces, and model building (Liu and Deng, 2009;Pelorosso et al, 2009;Tang et al, 2009). Recently, land change science has emerged as a fundamental component of global environmental change and sustainability research (Turner et al, 2007).…”

Abstract:Human activity intensity is a synthesis index for describing the effects and influences of human activities on land surface. This paper presents the concept of human activity intensity of land surface and construction land equivalent, builds an algorithm model for human activity intensity, and establishes a method for converting different land use/cover types into construction land equivalent as well. An application in China based on the land use data from 1984 to 2008 is also included. The results show that China's human activity intensity rose slowly before 2000, while rapidly after 2000. It experienced an increase from 7.63% in 1984 to 8.54% in 2008. It could be generally divided into five levels: Very High, High, Medium, Low, and Very Low, according to the human activity intensity at county level in 2008, which is rated by above 27%, 16%-27%, 10%-16%, 6%-10%, and below 6%. China's human activity intensity was spatially split into eastern and western parts by the line of Helan Mountains-Longmen Mountains-Jinghong. The eastern part was characterized by the levels of Very High, High, and Medium, and the levels of Low and Very Low were zonally distributed in the mountainous and hilly areas. In contrast, the western part was featured by the Low and Very Low levels, and the levels of Medium and High were scattered in Gansu Hexi Corridor, the east of Qinghai, and the northern and southern slopes of Tianshan Mountains in Xinjiang.

“…Finally, it should be noted that the ability to update this exposure map because, once known the keys for interpretation, it depends on land use update, that could be very fast and cheap using remote sensing technologies (Serra, Pons, & Saurí, 2008;Wood, 2009;Pelorosso, Leone, & Boccia, 2009). Likewise, changes in the behaviour of population (for example changes in the leisure spaces) or in the space functionality (for example a company closure) can be easily introduced through a reassessment of human exposure maps.…”

Mapping temporally-variable exposure to flooding in small Mediterranean basins using land-use indicators

2011

Keywords:Maps of exposure Risk Floods Hazard Land use a b s t r a c t This article deals with mapping exposure (or external vulnerability) to flood risk in two typical Mediterranean ephemeral streams: the Barranco de Carraixet and the Rambla de Poyo. The floodplains of both streams are within the metropolitan area of the city of Valencia (Spain's third largest city). Following the Mediterranean model, they are very fertile areas (with intense periurban and highly productive agriculture) which have recently absorbed the great urban expansion of the metropolis. Hydrologically these basins remain dry for most of the year, but become particularly dangerous during flash-flood events. They generate a risk pattern highly dependent on exposure since, in general, the hazard factor is very difficult to map, given the unpredictable nature of flash-floods.This work constitutes a proof of concept based on simple estimators obtained from land uses. External vulnerability or exposure is evaluated as a function of economic land value and human exposure to hazard. Land value is directly taken from the cadastre whilst human exposure is indirectly estimated from the location of population in relation to timeeactivity profiles. The temporal dimension is introduced and three exposure scenarios have been mapped, related to different time periods: working days, nights, weekends and holidays.The results show different patterns of exposure for each plain. In Carraixet floodplain exposure is greater at night and on weekends and holidays than during working hours, on account of the dominant agricultural and residential land uses. In the Poyo plain there are no major contrasts in absolute terms between day and night time, although spatial patterns of exposure vary from day to night: during the day, exposure is higher in industrial and commercial areas (around communication routes) whilst at night residential areas show more exposure.

“…The Mediterranean region has been affected by anthropic disturbances for thousands of years, and is, today, one of the most significantly altered hotspots in the world, with Italy following this general trend (Dalla Valle et al, 2009;Niedertscheider and Erb, 2014;Pelorosso et al, 2009;Shelef et al, 2016). Concurrently, the Mediterranean hotspots, similarly to other sites of biodiversity, are characterized by high human population densities (Aben et al, 2016).…”

A B S T R A C TWe conducted a GIS spatial analysis with the aim of providing the first quantitative large-scale overview of the distribution patterns of 1536 type localities (loci classici) of 1216 Italian endemic vascular plants and their relationship with a set of descriptive variables. Whereas some variables were used to model the presence-absence distribution patterns of the type localities for the whole set of endemics as well as for the subset of narrow endemics, others (e.g., presence inside or outside protected areas and Italian Important Plant Areas) were considered with the purpose of assessing potential assets or risks for conservation.The largest number of type localities was found within the Mediterranean biogeographic region (1134),http://dx
