“…The analysis indicates some systematic transitions involving an increase in urban areas and a decrease in agricultural areas, as well as the transformation of forest types and the episodic occurrence of wildfires. The analysis also reveals a continuous increase in the number of polygons between 1958 and 2011, which demonstrates the fragmentation of the landscape, representing a fast expansion process with new corridors [4] with impacts on natural systems and landscape homogeneity [59,60]. In the study area, and having as focal point the city center-center of the considered circle, two different transformations can be observed.…”

Medium/small sized cities create a polycentric urban system representing the backbone of their territory, characterized by profound changes on land use. The objective of this study is to evaluate the spatial and temporal dynamics of land use in a medium/small city in Portugal during the period 1958-2011, and the relation with the planning framework. The assessment involves land use changes recognition in the period 1958-2011, calculation of the stability grade indicator, and the losses and gains between classes. The rate of artificialization and its relation with the planning framework was also evaluated. The results for the city of Viseu showed a main decrease in annual crops and arable lands, with an increase of the continuous and discontinuous urban fabric. The changes are systematic transitions, marked by planning framework and its typology, objectives and scale enforcement. A plan addressing the city encouraged land use changes in the fringe, while a municipal Master Plan determined sequent transformation in all areas. The land use changes and the artificialization processes enabled the identification of three periods where planning framework was forthright. The study underlines the importance of a planning framework for medium/small sized cities for urban sprawl and artificialization processes.

“…According to the study, the area loss of agricultural land with high fragmentation, which was stated to have negative effects on humans and nature [45,46], was already a severe problem in large cities like Shanghai around the world [47,48]. As a result, the rapid reduction of arable land and the prevailing abandoned farmland in this area not only resulted in great waste of land resources, but also decreased the resilience of eco-environment [49].…”

Abstract:Quantifying the landscape pattern change can effectively demonstrate the ecological progresses and the consequences of urbanization. Based on remotely sensed land cover data in 1994, 2000, 2006 and a gradient analysis with landscape metrics at landscape-and class-level, we attempted to characterize the individual and entire landscape patterns of Shanghai metropolitan during the rapid urbanization. We highlighted that a roadscape transect approach that combined the buffer zone method and the transect-based approach was introduced to describe the urban-rural patterns of agricultural, residential, green, industrial, and public facilities land along the railway route. Our results of landscape metrics showed significant spatiotemporal patterns and gradient variations along the transect. The urban growth pattern in two time spans conform to the hypothesis for diffusion-coalescence processes, implying that the railway is adaptive as a gradient element to analyze the landscape patterns with urbanization. As the natural landscape was replaced by urban landscape gradually, the desakota region expanded its extent widely. Suburb areas witnessed the continual transformation from the predominantly rural landscape to peri-urban landscape. Furthermore, the gap between urban and rural areas remained large especially in public service. More reasonable urban plans and land use policies should push to make more efforts to coordinate urban-rural development. This study is a meaningful trial in demonstrating a new form of urban-rural transects to study the landscape change of large cities. By combining gradient analysis with landscape metrics, we addressed the process of urbanization both spatially and temporally, and provided a more quantitative approach to urban studies.

“…The conglomerates allowed us to define landscape units with homogeneous characteristics [44], aspect that provides a general understanding of the dynamics of the undergone changes in the basin [12]. The cluster analysis clearly defined zones with similar characteristics; the cells that created each group tend to occur together due to spatial autocorrelation in the original variables used [42].…”

“…The chronological delineation of landscape units in some way reflects the pressure exerted by socio-economic activities tending to exploit the resources which are ongoing today in many regions of the world [44]. In 1983, there was little modification of the vegetation cover, aspect that determined the presence of only three landscape units, each consisting of wooded area, subtropical scrub, pastureland and, to a lesser extent, cropland (Figure 3).…”

“…The change in land use that leads to the delineation of landscape units and fragmentation of the territory is related to ideological, political and market trends. Most of the distribution of crops in the study area was a result of the emergence of transnational corporations combined with those already in existence, which are in competition for the exploitation of natural resources, a situation facing many regions worldwide today [44].…”

Historical Delineation of Landscape Units Using Physical Geographic Characteristics and Land Use/Cover Change

Landscape units are conceived as a part of the territory that share similar physical and geographic characteristics. Their delineation can contribute to identify the physical and social dynamics that emerge in the spatial environment and to propose strategies of planning and management of the territory. The main objective was to make a historical delineation of landscape units in the Duero river basin that demonstrate the dynamics of changes in the territory, the description of the actors involved, and the affectations in the natural and social environment. We analyzed the vegetation change and urban growth from 1983 to 2014, incorporating climatic, edaphic, and topographic variables. A Principal Component Analysis was performed with the information and results were used in Maximum Likelihood procedure to define different clusters based on environmental characteristics. We defined five categories from the Landsat images. Results showed landscape units with homogeneous environmental characteristics and some differences in the units' delineation were mainly influenced by political and socioeconomic factors. Temporally there was an increased tendency of landscape units, three in 1983, nine in 1990, 1995, 2000 and 2011, and eight in 2014. This increase resulted from territory fragmentation because of berries and avocado cultivars expansion over wooded area.
