There are both semantic and technical differences between land use (LU) and land cover (LC) measurements. In cartographic approaches, these differences are often neglected, giving rise to a hybrid classification. The aim of this paper is to provide a better understanding and characterization of the two classification schemes using a comparison that allows maximization of the informative power of both. The analysis was carried out in the Molise region (Central Italy) using sample information from the Italian Land Use Inventory (IUTI).

Several recent reports on cropland soil organic carbon (SOC) stock changes throughout Europe indicate a general continuing loss of SOC from these soils. As most arable soils in Europe are not in an equilibrium situation because of past changes in land-use and management practices, shifts in both have been suggested to drive this decline of SOC stocks. A lack of data has prevented the unambiguous verification of the contribution of these factors to SOC loss.

Land-use/land-cover change is the most important factor in causing biodiversity loss. The Mediterranean region has been affected by antropic disturbance for thousands of years, and is, nowadays, one of the most significantly altered hotspots in the world. However, in the last years a significant increase in forest cover has been measured. These new patterns are independent from planned conservation strategies and appear to have a substantial impact on landscapes and biodiversity.

Recent advances in fire management led landscape managers to adopt an integrated fire fighting strategy in which fire suppression is supported by prevention actions and by knowledge of local fire history and ecology. In this framework, an accurate evaluation of fire ignition risk and its environmental drivers constitutes a basic step toward the optimization of fire management measures.

An analysis is made of the land use transformations over the last sixty years, as well as the consequences of these transformations on the naturalness of the territories of three municipalities of the Nuovo Circondario Imolese (Bologna, Italy). The selected municipalities are: Medicina, Borgo Tossignano and Castel del Rio, which represent the main territorial aspects of the Nuovo Circondario Imolese.The land use transformations are quantified through the GIS comparison of the land use maps of the years 1995, 1976, 1994 and 2003.

A study on different types of bioindicator was carried out to detect river habitat quality in Central Italy. It was investigated the effectiveness of different bioindication models based on three biotic components: (i) vascular plants – hemeroby index for aquatic (Hw) and terrestrial species (Hₛ), and Ellenberg's soil nutrients indicator (N); (ii) aquatic macroinvertebrates – extended biotic index (EBI); (iii) soil microarthropods – index of soil biological quality (QBS-ar).

The present study investigates the relationship between land degradation and the evolution of the productive structure in Italy during the last 50Â years (1960â2010). The objectives of the study are twofold: (i) to present and discuss an original analysis of the incomeâenvironment relationship in an economic-convergent and environmentalâdivergent country and (ii) to evaluate the impact of the (changing) productive structure and selected socio-demographic characteristics on the level of land vulnerability.

Nature conservation is a very important issue in the sustainability assessments and spatial planning context. Knowledge of the suitability of the land to behave as an ecological corridor thus provides very significant input to land-use planning. Nature conservation and land-use planning are by their nature spatial problems.

Land degradation is a process negatively affecting environmental sustainability and requires permanent monitoring for understanding its nonlinear trajectories of change over time and space. Environmental sustainability is linked to a theoretical definition of dynamic balance among various components contributing to the ecosystem quality and functioning.

The aims of this study are to describe the ecological classification of land in Italy and to show how the resulting land units can act as reliable frameworks for coarse scale environmental analyses that can be used to implement national conservation strategies. We first collected, homogenised and drew physical thematic maps, which were then linked to biological and human features. We then performed a gap analysis of land heterogeneity compared with Natural Protected Areas and Natura2000 network on the basis of three categories: Total gaps, Partial gaps, and Protected.
