    Description: Following the Great Recession (2007–2009), growth in multiunit housing starts has been exceptionally strong and sustained. In this study, we examine empirical evidence for three possible explanations, namely, the passage of Baby Boomers into senior years, the depressed economic conditions, and rising preference of recent birth cohorts for residing in urban cores. Applying Age-Period-Cohort analysis to census data on multiunit housing occupancy from 1970 to 2010, we find evidence to support the explanations that a sharp increase in demand from Millennials drawn to urban cores and retiring Baby Boomers are contributing to the growth in multiunit housing starts. The results provide weak evidence of a negative relationship between depressed economic conditions and demand for multiunit housing starts. Over the long term, demand for multiunit housing can be expected to moderate as a result of the projected aging of the population.

    Description: Shrinking populations have been gaining increasing attention, especially in postsocialist Eastern and Central European countries. While most studies focus on specific cities and regions, much less is known about the spatial dimension of population decline on the national level and the local factors determining spatially uneven population change. This study uses Lithuanian census data from the years 2001 to 2011 to get insight into the geography of population change for the whole country. Lithuania has experienced one of the highest rates of population decline in the world in the last decades. The predictive models show that regional factors have a strong effect on the variation in population change throughout the country but also reveal that sociodemographic and economic area characteristics play a role in the process of decline. Our results give little hope to those who would like to reverse the ongoing trends of population change and emphasize the need for spatial planning to cope with the changes. This is an approach which currently does not exist in practice in Lithuania.

    Description: This study presents the analysis of Akure urban land use change detection from remote imagery perspective. Efforts were made to examine the direction that the continuous expansion of the city tends towards since its inception as a state capital in 1976. Using Aerial Imagery Overlay (AIO), the pattern of land use changes in Akure and its environs were determined. This involves imageries interpolation and overlaying to determine the land use changes, direction, and extent of the expansion. Findings revealed unguided expansion in the growth of the city which affects the pattern of land uses within the city and, by extension, into the adjoining settlements. There were incompatible conversions in land uses and undue encroachment into green areas in the adjoining communities. The study suggests effective zoning strategy on unguided nature of urban development whose effects on land use are very prominent in the study area. Adequate monitoring by the Development Control Department and other stakeholders in urban planning is equally suggested to mitigate the incompatible land use changes in the area.

    Description: The lower-class segment of the population of the developing nations often fails to form meaningful social relations and remain disengaged from essential social institutions. The research examines those people who live in refugee-camp and sullied slum of Dhaka city and inspect how much they are socially isolated. Certain characteristics, taken as indicators to test the level of social isolation, indicate that a large segment of camp and slum dwellers are feeling isolated. However, the evidence shows no differences in the predicted direction with respect to the objective demographic variables; nonetheless, a pattern of perceived social isolation was found from the survey data.

    Description: Research on urban heat island (UHI) mitigation has been carried out globally. Several strategies have been proposed or developed to mitigate UHI, including highly reflective (HR) envelopes of buildings, green roofs, urban vegetation, shading, heat sinks, and air-conditioning efficiency. Among these techniques, HR envelopes have been extensively studied as an effective method to mitigate the UHI effect by reducing energy consumption. However, because most of HR materials are diffusive, HR envelopes applied to vertical surfaces can reflect both onto roads and nearby buildings. Additionally, HR roofs cannot reflect all incoming solar radiation to the sky if there are high buildings around it. Thus, HR materials applied as building envelopes have a limited effect against the solar contribution to the UHI. In order to solve this problem, retroreflective (RR) materials, which reflect the solar radiation back towards the source, have been studied and developed to be applied as building envelopes instead of HR materials. This paper summarizes several previous researches on HR envelopes and cool roofs and summarizes several current researches on RR materials. The potential for application of RR envelopes in cities is proposed with consideration of economic and environmental factors.

    Description: This study was undertaken to obtain direct and useful data that support biodiversity awareness and management in two cities of Niger. 800 questionnaires were administrated to the populations of Niamey and Maradi. The results show that 99% of respondents are aware of the importance of biodiversity in urban areas. They assign multiple roles to it; however, climatic and managerial reasons explain why plants are most preferred to animals in these cities. Furthermore, shade and fruits are the criteria for plant species selection, and that explains the abundance of Azadirachta indica A. Juss. and Mangifera indica L. Even though plants are preferred to animals in houses, 47% of the respondents practice animal husbandry. Most of the animals are left wandering with risks of destruction of green areas, road unsafety, and zoonotic contamination. The results of this study also showed the ignorance of 55% of the respondents about the presence of wildlife in urban areas. The proliferation of cockroaches and rats could be an indication of insanitary conditions that are faced in some areas of the cities as mentioned by 81% of the respondents. This study shows the importance of local knowledge in the identification process of urban problems.
