The paper presents findings of research about the classification of New Belgrade?s super-blocks using the typomorphology approach and the morphogenetic analysis of urban morphology in relation to land use. The example of New Belgrade is particularly interesting given the fact that the morphological patterns of land use within its superblocks were created during the period of non-market economy in Socialism, and now it is possible to review the effect that the socio-political transition into Capitalism, which started in the 1990s, has had on its land use. As a result, a data base with the typology of residential super-blocks of New Belgrade is created: from the perspective of urban land use there are four main morphological types (with the subtypes) taking into account the morphology of the position of the buildings on the terrain, and traffic (cars-pedestrian) flows. The morphogenetic analysis reveals that after the 1990s there are processes pointing to powerful influence of land policy driven by private interests. Research findings suggest that nowadays there are negative trends of using the land in super-blocks in New Belgrade - e.g. percentage of land occupancy by buildings is getting bigger and almost 100% of the un-built soil in the newly developed super-blocks is covered /paved.

This paper aims to establish a methodology for urban land use planning and management that provides an insight into the hierarchy of priorities between a large number of activities for planning actions, thus contributing to the concept of energy-efficient housing. This methodology includes three aspects of sustainable development: Economic, ecologic, and social, which serve as an overall criterion within which urban planners could make assessments of planned activities. The assessments are the core of the methodology—every aspect is assessed by concerning its costs, consequences on the urban environment, and the effects on the citizens’ quality of life. Ten experts were involved to prove the methodology’s effectiveness. As a result, a hierarchy between the activities is created, which would help an urban planner prioritize and order further activities. The applicability of the hierarchy was tested through a simulation of a reconstruction process of a collective housing area in New Belgrade, Serbia, from the view-point of land use and accessibility. This methodology contributes to the creation of the prioritized groups of activities, and a finalized hierarchy of the activities, while its application is seen in the process of making urban plans, and defining recommendations for its implementation.

Radon is the most important of all sources of natural radiation, and it belongs to the main air pollutants in closed space. It is necessary to develop awareness of its harmful effects in buildings in order to take appropriate measures to reduce the risk of exposure to it. This study assesses public awareness of radon-related risks in Serbia by analyzing four areas: general public, legislative framework, professional practices, and student knowledge. Data were collected from media sources, legal documents, conferences and scientific publications, and surveys among students of University of Belgrade. Student answers have shown that they are not aware of the danger of radon in buildings: there is a gap between knowledge about radon and about its effects in the interior space. The results also show low presence of this topic in the media and in professional circles in Serbia. This paper is a contribution to the overall efforts to spread awareness in Serbia about the problem of the presence of radon in closed spaces and the health problems it can cause. This is also important in the context of the search for energy-efficient building solutions, where the passive house is emerging as the most sustainable form. It is a relatively new concept in Serbia, so information about the harmful effects of radon in indoor spaces and about the implementation of certain strategies in passive construction for protection against radon is necessary in order to protect the health of the environment and the population.

Walkability for non-motorized users is crucial for fostering inclusive, healthy, and sustainable communities. By prioritizing modern human-centered design principles, social equality is promoted for all categories of users, regardless of physical abilities or socio-economic status. Despite the importance of this indicator, a series of inconsistencies that produce inadequate and inaccessible urban space can still be observed in cities. The aim of this paper is to present the methodology for the calculation of the walkability index at the local level. This new methodological procedure considers walkability for pedestrians, with a special focus on people with reduced mobility. Based on specifically defined criteria, initial calculations were performed and integrated into the dynamic walkability index (DWI). One of the main advantages of this index is that it includes the dynamic component of the share of different categories of users in the total sample, which enables simple time modification without repeating the entire procedure. The developed methodology can be used as a tool for ranking existing street segments according to the urgency of reconstruction, while on the other hand promoting equality and inclusion of all categories of users in decision-making processes, thus creating more comfortable and safer environments.

Context: the modern city and the privatization of space that occurs as a consequence of the economic interest of dominant social groups that treat space as a source of capital in the capitalist system. The reduction of public space or its transformation into commercial spaces leads to the creation of new public spaces that are privately owned and with a controlled use regime, with the intention of taking over the role of social spaces. Focus: due to the need for new space because of constantly growing objects of consumption, virtual space as an extension of real space allows performing functions without exhausting physical space, but it also affects our understanding of sociality as it takes on the role of providing social interaction that is historically associated with the city square and streets as well as with the trade function. This paper is about the new social space, as well as the changes in physical space that occur in contemporary social circumstances of rapid technological development.

One of the challenges of the modern world is climate change, the catastrophic consequences of which experts warn about, and which have become increasingly visible in recent decades. Within the broad field of climate change, the issue of water stands out - from large floods and rising sea and ocean levels that threaten coastal cities and settlements to drinking water shortages and droughts that degrade agriculture. In urban areas with large areas of impermeable surfaces, there is no natural water circulation - in the worst cases, almost 100% of the rain that falls remains on the ground. Rural, agricultural areas, unlike this, leak up to 35% of rainwater into the ground, about 50% returns to the atmosphere as water vapor and only 15% remains on the ground. In this regard, experts today, for rainwater and wastewater collection procedures, propose the application of the "soft engineering" system as a concept of ecological engineering with the aim of minimizing the impact on the environment, as opposed to the conventional "hard engineering". The paper will explain the "soft engineering" system as a part of the modern sustainable system of infrastructure in cities, and will point to modern approaches to the inclusion of water management issues in urban areas and urban planning with a presentation of key examples from world practice.
