“…Various studies [28,38,39] pointed out the relationship between environmental and socioeconomic variables affecting land degradation, especially for what concerns the Mediterranean region. The approach developed here allows for a multi-temporal assessment of land quality in metropolitan areas, providing comprehensive information to policy strategies combating land degradation.…”

Land degradation has expanded in the Mediterranean region as a result of a variety of factors, including economic and population growth, land-use changes and climate variations. The level of land vulnerability to degradation and its growth over time are distributed heterogeneously over space, concentrating on landscapes exposed to high human pressure. The present study investigates the level of land vulnerability to degradation in a shrinking urban area (Rome, Italy) at four points in time (1960, 1990, 2000 and 2010) and it identifies relevant factors negatively impacting the quality of land and the level of landscape fragmentation. A multi-domain assessment of land vulnerability incorporating indicators of climate quality, soil quality, vegetation quality and land management quality was carried out based on the Environmentally Sensitive Area (ESA) framework. The highest rate of growth in the level of land vulnerability was observed in OPEN ACCESSSustainability 2015, 7 11981 low-density suburban areas. The peri-urban mosaic formed by coastal woodlands and traditional cropland preserved high-quality land with a stable degree of vulnerability over time. Evidence suggests that the agro-forest mosaic surrounding Mediterranean cities act as a "buffer zone" mitigating on-site and off-site land degradation. The conservation of relict natural landscapes is a crucial target for multi-scale policies combating land degradation in suburban dry regions.

“…Finally, it should be noted that spatial analysis techniques have been used in many of the applications, in particular Geographical Information Systems (GIS) [30,31], which make it possible to integrate information generated from remote sensors, GPS, vectorial superposition, map algebra, field work, etc. Further examples may be found in [32], who used an indicator model with which they identified Drivers-Pressures-State-Impact-Responses (DPSIR) in the coastal zone of Granada (Spain) to explore the interactions and dependence of territorial dynamics in relation to the availability of water as a limiting resource.…”

Coastal zones are very dynamic and fragile environments, constituting a landscape ever more heterogeneous, fragmented and with increasing levels of complexity due to the changing relationship between man and nature. Integrated coastal zone management therefore requires detailed knowledge of the system and its components, based-to a large extent-on technical and scientific information. However, the information generated must be in line with the political requirements necessary for decision-making and planning. Thus the use of indicators to give a simplified view of the many components of the territory, and at the same time to provide important information about patterns or trends, becomes a tool of the utmost importance. These indicators can be understood as measurable characteristics of the environment, which facilitate comprehension of the processes occurring at different scales and serve as a reference to inform the population and support decision-making. The aim of the present note is to demonstrate briefly the need to develop geographical-environmental and natural risk indicators to facilitate comprehension of the dynamic of spatial and temporal landscape patterns, particularly in coastal environments. This approach offers an historical summary of the natural, socio-economic and political processes which currently make up the territory, and which without doubt will continue to influence it in the future. At the same time, it is proposed that information should be integrated on the basis of this framework with a view to generating spatial decision support systems in a context of planning and integrated management of the coastal zones of Chile.

“…The water deficit during several months requires irrigation while low quality water is used in the poorly drained soils of these coastal plains, being soil salinization an environmental problem. Thus, the study area soils are subjected to severe risk of physical, chemical and biological degradation (De Paz et al, 2006) that endanger agriculture sustainability.…”
