We are witnessing a paradox in the consumption space, in relation to retail activity within urban and suburban areas: One can observe over‑retailed areas, featuring retail chains and shopping malls, oftentimes occurring close to other unoccupied, abandoned, dying shopping malls, called dead malls. The phenomenon of dead malls is widespread in the USA, is strongly visible in Canada and China, and is now starting to occur more often in Europe. This paradox can be partially explained using a series of concepts, and in this paper we introduce the main pillars in understanding the socio‑economic reasons and the spatial patterns contributing to this phenomenon. The research method employed here is the ESDA (Exploratory Spatial Data Analysis).

The presence of wildlife in each forest represents the prolific eco-system, wealth and fertility of the region. The literatures on the species distribution consider the global and climatic factors, with special attention to local condition, where the species exists. This study analyzes various factors (Environmental, Social, Economic, Institutional) associated with the existence of the species (Pavo Cristatus) within the forest range of Coimbatore region in two different years (2005 and 2013). A regional level perspective is carried out by investigating the factors associated with the distribution of Pavo Cristatus and estimates the impacts on the species found during analysis. The proposed analysis makes use of Exploratory Spatial Data Analysis (ESDA) to visualize and analyze the local spatial distribution of the species. The results reveal that no exclusive single aspect, but a collection of common factors regulates the species distribution. Further the analysis indicates that the augmentation of species distribution in an area is a healthy sign of the forest regions

Abstract As the world moves towards urbanization, the demand for land for urban land use increases. If left unmanaged, this might result in the wastage of land that could have been used for more productive purposes, such as agriculture. Other developments can also pose risks to the environment and to those who inhabit it. Therefore, land suitability analyses must be carried out before proceeding to urban planning. This study produced an urban suitability analysis of the municipality of Diffun in Quirino Province as a basis for future urban planning. Conducting this analysis will be very timely, considering that the revision of the municipality’s Comprehensive Land Use Plan (CLUP) will start in 2021. In this study, two methods of doing the analysis were integrated: Boolean overlay and weighted overlay. Using the gathered spatial data, a total of 18 factors and restrictions were produced for the analysis. Restriction layers used in the Boolean overlay method include existing built-up areas, erosion risk, flooding susceptibility, protected agricultural lands, other protected lands, Quirino Protected Landscape (QPL), slope, waterway buffers, and ecotourism site buffers. Meanwhile, the weighted overlay analysis used the following factors: elevation, land-use type, distance to ecotourism sites, distance to local roads, distance to national and provincial roads, proximity to the downtown, distance to protected agricultural lands, distance to waterways, and slope. The weights of the factors were calculated using a pairwise matrix. The study concluded that only 0.32% of the total land area of the municipality is most suitable for urban land-use, while 87.36% is considered not suitable for the development of built-up areas.
