“…Mean values of UA and PA are given in Table 2 for each class. Assessing class-wise UA and PA provides more insight in the classification accuracy of individual classes [53]. Most of the LULC classes have more than 70% UA and PA in each of the years indicating good classification accuracy as generally accepted.…”

“…This study offers a detailed account of urbanization in the largest urban settlement in the Himalaya, providing a gauge to compare urban growth in cities located across different mountain valleys. Evidence from Himalaya suggest an increasing urbanization extent [38,54] along with potential landscape ecological risk from the coupled effects of growth [53]. A major attempt at understanding the urban growth in Himalayan cities was made by Diksha and Kumar [54], analysing their urban sprawl and land consumption pattern.…”

Analysis of urban dynamics is a pivotal step towards understanding landscape changes and developing scientifically sound urban management strategies. Delineating the patterns and processes shaping the evolution of urban regions is an essential part of this step. Utilizing remote-sensing techniques and Geographic Information System (GIS) tools, we performed an integrated analysis on urban expansion in Srinagar city and surrounding areas from 1999 to 2017 at multiple scales in order to assist urban planning initiatives. To capture various spatial indicators of expansion, we analysed (i) land use/land cover (LULC) changes, (ii) rate and intensity of changes to built-up areas, (iii) spatial differentiation in landscape metrics (at 500, 1000 and 2000 m cell-size), and (iv) growth type of the urban expansion. Global Moran’s I statistics and local indicators of spatial association (LISA) were also employed to identify hotspots of change in landscape structure. Our methodology utilizes a range of geovisualization tools which are capable of appropriately addressing various elements required for strategic planning in growing cities. The results highlight aggregation and homogenization of the urban core as well as irregularity and fragmentation in its periphery. A combination of spatial metrics and growth type analysis supports the supposition that there is a continuum in the diffusion-coalescence process. This allows us to extend our understanding of urban growth theory and to report deviations from accepted stages of growth. As our results show, each dominating growth phase of the city—both diffusion (1999) and coalescence (2009 and 2017)—is interspersed with features from the other type. An improved understanding of spatial differentiation and the identification of hotspots can serve to make urban planning more tailored to such local conditions. An important insight derived from the results is the applicability of remote-sensing data in urban planning measures and the usefulness of freely available medium resolution data in gaining a comprehensive understanding of the evolution of cities.

“…Road and infrastructure construction is considered to be an essential part of forestry as forests become sustainable and profitable only if they are connected with a suitable road network, (see, for example, road network assessments in Europe [1], Turkey [2], the Himalayas [3], and the Amazon [4]). With the construction of forest roads, any forest can potentially be opened for financial gain and sustainable maintenance; they are the skeleton of integrated openings of forests, mountains, etc., and are the basis for any activity.…”

Forest traffic networks receive considerable structural stress from supporting heavy vehicles and machinery. Usually, in forest areas, artificial waterways are constructed on the side of the road and feature open constructions, so that solid materials blocking the waterways may be easily cleared. The use of closed bridges at vehicle crossing points, though infrequent, necessitates the use of installing closed water pipelines of large diameters. However, these closed, reinforced concrete (RC) water pipelines suffer structural damage over time. Here, we propose the strengthening of existed old concrete pipes using sheets of carbon fiber reinforced polymer (CFRP) at increasing levels. The assessment of the results, which were conducted in ABAQUS, is done in light of the stress tests and suggests that the use of a simple, cost-effective method, such as the installation of composite materials, can potentially increase the structural strength of these pipes and allow their re-use for forest roads.

“…In recent years, a morphological spatial pattern analysis method (MSPA) focusing on measuring structural connectivity has been introduced into the identification of ecological sources. Emphasizing on structural connection, this method only depends on land use data [14][15][16]. After the classification of land use to extract forest, wetland, water, and other natural ecological elements as a foreground and other land use types as the background, a series of image processing methods are used to divide the foreground into seven non-overlapping categories (namely, core, bridge, ring, edge, branch, loop, islet, and performation), and then landscape types that are important for maintaining connectivity are identified, which increases the scientific nature of ecological source and ecological corridor selection [17,18].…”

The rapid urbanization process, accompanied by the transformation of high-intensive land development and land use, constantly encroaches on habitat patches, making them increasingly fragmented and isolated, which directly influences the regional landscape pattern and sustainable development. Taking the Tomur World Natural Heritage region as the study area, the morphological spatial pattern analysis (MSPA) method and landscape index method were used to extract the ecological source areas of great significance to the construction of ecological corridors. Then, using the minimum cumulative resistance model (MCR), the comprehensive resistance surface was constructed and the potential corridors were generated by the minimum cost path method. Finally, according to the gravity model, the important corridors of the study area were designed. Results showed that the MSPA method and MCR model can be used in combination to identify the potential ecological corridors in the study area and clarify the priority of landscape element protection in the study area, which can provide guidance to construct the ecological network and provide reference for other regions as well.
