The urban footprint of rural forced displacement

AbstractThe rapid growth of marginal settlements in the Global South, largely fueled by the resettlement of millions of internally displaced people (IDPs), underscores the urgent need for tailored housing solutions for these vulnerable populations. However, prevailing approaches have often relied on a one-size-fits-all model, overlooking the diverse socio-spatial realities of IDP communities. Drawing on a case study in Medellin, Colombia, where a significant portion of the population consists of forced migrants, this interdisciplinary study merges concepts from human geography and urban theory with computational methods in remote sensing and exploratory spatial data analysis. By integrating socio-spatial theory with quantitative analysis, we challenge the conventional housing paradigm and propose a novel framework for addressing the housing needs of IDPs. Employing a three-phase methodology rooted in Lefebvre’s theoretical framework on the production of space, including participatory mapping, urban morphology characterization, and similarity analysis, we identify distinct patterns within urban IDP settlements and advocate for culturally sensitive housing policies. Our analysis, focusing on Colombia, the country with the largest IDP population globally, reveals the limitations of standardized approaches and highlights the importance of recognizing and accommodating socio-cultural diversity in urban planning. By contesting standardized socio-spatial practices, our research aims not only to promote equality but also to foster recognition and inclusivity within marginalized communities.

Water, sanitation, and hygiene service inequalities and their associated factors among urban slums and rural communities in Eastern Ethiopia

BackgroundUnderstanding the level of inadequate water, sanitation, and hygiene (WaSH) services in urban and rural settlements is crucial for prioritizing community interventions and resource allocation. However, there is a lack of evidence regarding discrepancies in WaSH services across rural and urban slum communities in Ethiopia.ObjectiveThis study aims to assess inequalities in households’ WaSH services and their associated factors among urban slums and rural communities in Eastern Ethiopia from February to April 2024.MethodsA comparative community-based cross-sectional study design was conducted, with study participants selected through stratified random sampling using proportional-to-size allocation. Data were entered into Epi Data version 3.1 and then exported to STATA version 17 for analysis. Bi-variable and multivariable logistic regression was conducted, and associations were reported as odds ratios (ORs) with 95% confidence intervals (CI), using a p-value less than 0.05 as the significance threshold.ResultA total of 278 urban and 301 rural households participated in the study, with a response rate of 94%. Key indicators showed that WaSH services were significantly better in urban areas compared to rural households. For example, 98% (95% CI: 96, 99) of urban households had access to an improved water source compared to 76% (95% CI: 71, 80) of rural households. The proportion of households with improved latrines was 44% (95% CI: 38, 50) in urban areas and only 14% (95% CI: 11, 19) in rural areas. Handwashing practices at all five critical times were reported by 52% (95% CI: 46, 58) of urban household heads, compared to 22% (95% CI: 18, 27) of rural households. Additionally, occupation (such as being a farmer, p = 0.000) and water service satisfaction (p = 0.000) were significantly associated with these key WaSH outcomes.ConclusionThe study revealed that the WaSH services in urban slums are considerably better than in rural households. Socioeconomic factors significantly influence the existing disparities in WaSH services. Stakeholders should focus on providing targeted, strategic support to communities to address the challenges in WaSH service provision.

Identifying the Urban Development Pattern of Subway Cities Using Predictive Analysis

Starting from the hypothesis that there are structural differences in urban development between cities that have implemented underground transport and those that have not, the paper aims to provide a predictive analysis model to identify cities that show the pattern for the development of the subway network. In order to identify the predictive analysis model capable of classifying urban settlements, the predictive analysis part consisted of two stages. In the first stage, a Random Forest classification model will be estimated on a sample of the 27 capitals of the European Member States. Subsequently, based on this model, 9 cities in Romania will be classified from the perspective of the existence of the urban development pattern for the development of underground public transport. In order for the classification error of the predictive model to be as low as possible, variables from all areas specific to urban development (economic development, population density, circular economy, green city, digitalization, urban mobility) were used. The element of originality of the paper consists in calculating variables on the area of urban mobility, urban infrastructure and circular economy, using GIS coordinates. Thus, in addition to official international data sources, variables calculated by using geospatial technology (average distances, densities of green spaces, etc.) were included in this research. The main results of the research show that there are cities in Romania that present the same pattern of development similar to the capitals of the Member States of the European Union that have implemented underground public transport. Therefore, it can be said that for these cities it is necessary to implement this type of transport, the depreciation of the investment representing an easy process, which can be achieved in a medium or short term.

FEATURES OF TRAINING A YOUNG DOCTOR IN MODERN CONDITIONS

Reforming the system of primary health care in healthcare in the Russian Federation over the past decade has been a priority task of the state. On instructions from the President, the Government continues to create conditions to increase the availability of medical care. A decision was made to expand the capabilities of the primary health care development program in rural areas, urban settlements and small towns of the country. This resolution was signed by Prime Minister Mikhail Mishustin (Resolution No. 2226 dated December 21, 2023). In the course of the conducted survey of 128 district therapists of the Stavropol Territory who started medical practice immediately after graduation, the main problems they faced when starting their work were identified: lack of practical training for independent professional activity, the assignment of a mentor to not every young specialist; insufficient equipment of the workplace with the necessary tools; incomplete computerization jobs (especially in rural areas); not all district doctors are assigned nurses; the number of attached population in 1 therapeutic area exceeds the norm. The difficulties of the professional activity of young specialists were associated with an insufficient number of hours of practical training in 5-6 years of study at the university and the cancellation of the internship. In order to revive the traditions of mentoring and increase the level of competence of young district therapists who received a diploma after 2017, the Ministry of Health of the Stavropol Territory, together with the Department of Polyclinic Therapy of Stavropol State Medical University, organized the work of the "School of a young therapist", which showed great effectiveness in the practical activities of young doctors in the region.

The Restoration of New Gourna: Safeguarding the Legacy of Hassan Fathy

Hassan Fathy’s New Gourna project in Egypt (1946-52) is renowned as a pioneering example of sustainable urban settlement, integrating traditional technologies with modern architectural principles and serving as an inspiration to architects and planners worldwide. But decades of neglect have resulted in major structural deterioration and demolitions of the original buildings. In response, a project titled “Safeguarding Hassan Fathy’s Architectural Legacy in New Gourna” has been undertaken through a collaboration between UNESCO and the Egyptian Ministry of Culture, as defined by the National Organization for Urban Harmony (NOUH) for the period 2019-21. This initiative aims to conserve and repurpose the public heritage buildings while addressing the critical issue of groundwater. NOUH has now taken the project into a second phase (2023-24). This paper outlines the symptoms and causes of deterioration in New Gourna Village and reviews the restoration efforts applied to four major buildings: the khan, the mosque, the theater, and Hassan Fathy’s house. Further research will detail the restoration project in each case, including the documentation phase and the specific restoration techniques applied to each structural element and material.

Land rights, resource allocation and urban settlement choices of migrant workers in Yunnan, Western China

Using the cross-sectional data from the 2015 and 2021 Yunnan Migrant Workers Urban Integration Survey, this study assesses the different effects of the three types of land rights that migrant workers possess in their rural hometowns on their urban settlement choices in Yunnan, western China. Specifically, it examined the existence of migrant workers moving between urban and rural areas in response to the importance of land rights for rural migrant workers, in western China, a region with the lower level of economic development and fastest growing number of migrant workers in China. After controlling for the impact of other variables, the multinomial Probit model was used to estimate the impact of the migrant workers' land rights in their rural hometowns on their settlement choices in urban areas. We found that rural land rights significantly increased migrant workers' willingness to return to their hometowns. This indicates that land right security is a key factor affecting Yunnan migrant workers' urban settlement intentions, although it is conditional in terms of age groups and places of origin. Importantly, we found that migrant workers in western China are more inclined to keep their dual identities as both urban migrant workers and rural residents. They, hence, are more inclined to rationally allocate their resources between urban and rural areas to maximize their economic outputs. Particularly, they prefer to only working - rather than settling - in urban areas, while retaining their rural land as assets and income sources. Instead of settling in either urban or rural areas, the older migrant workers who migrate to smaller and economically underdeveloped cities are more inclined to drift between urban and rural areas without permanent settlement. This confirms the argument of livelihood resource maximization and migratory bird-type migration as important mechanisms via which land right ownership affects migrant workers’ urban settlement intentions. This study suggests that policymakers should consider the land rights of rural migrant workers when making urban settlement policies, especially for small and medium-sized cities, where migrant settlement intention is weaker. Policymakers should also promote the flexibility of rural land use rights transfer and explore reforms concerning the separation of the three types of land rights to achieve a balance between urbanization and land use efficiency, particularly in small and medium-sized cities.

Assessment of climate change knowledge of residents of informal sectors of Abuja Federal Capital City, Nigeria

ABSTRACT Urban informal settlement dwellers face uncertainties from climate change (CC) and need to understand its causes and impacts to adapt effectively. Few studies explore their levels of CC knowledge. This research surveyed 388 purposively selected households across five informal sectors in Abuja, Nigeria (Apo, Gaduwa, Garki, Jabi, and Mabushi), using structured questionnaires. Key variables assessed for their influence on CC knowledge included age, family size, education, income, livelihood type, tenure security, and marital status. Mann-Whitney and Chi-Square tests evaluated the significance of these factors. Findings showed that most households are aware of local CC trends, with perceptions closely aligning with scientific insights. However, understanding of CC causes and consequences remains limited. Among seven hypotheses tested, age, family size, income, and livelihood type significantly influenced CC knowledge, while education, tenure security, and marital status had little effect. The study highlights that even educated residents may lack comprehensive knowledge of CC causes. Enhancing scientific understanding in CC-prone communities is essential for effective adaptation and mitigation strategies.

Research on the evolution and driving factors of the coupling relationship among tourism industry, urbanization and human settlements of the urban agglomeration in the middle reaches of the Yangtze River.

This study examines the evolution of the coupling relationship among the tourism industry, urbanization, and human settlements of the urban agglomeration in the middle reaches of the Yangtze River from 2005 to 2019. By employing a constructed evaluation index system and a quantitative analysis model, the study aims to characterize and analyze this relationship. The key findings are as follows: (1) The coupling coordination level of the three major systems exhibits a continuous upward trend over the study period, albeit with a gradually slowing growth rate. The Changsha -Zhuzhou-Xiangtan urban agglomeration shows the highest average growth rate, followed by the Wuhan metropolitan area and the Poyang Lake urban agglomeration. (2) The variation coefficient and Taylor index of the coupling coordination degree demonstrate a fluctuating downward trend, indicating a convergence in spatial differences in interregional coupling coordination levels. Internal differences between city clusters within urban agglomerations are identified as the main source of overall differences in coupling coordination levels. (3) The coupling coordination levels of the three major systems follow an evolutionary trajectory characterized by "serious imbalance, moderate imbalance, mild imbalance". Clear features of level transitions are observed among various cities. (4) The endowment of tourism resources emerges as the primary factor driving the evolution of the coupling relationship among the tourism industry, urbanization, and human settlements. The study highlights the increasing diversification of driving forces and significant spatiotemporal heterogeneity in interregional driving forces for coupling relationship evolution factors.

User Perception-Based Optimal Route Selection for Vehicles of Disabled Persons in Urban Centers of Saudi Arabia

People with disabilities (PWD), in their routine commutes, confront hindrances associated with road infrastructure in busy urban centers. The present study developed a user perception-based methodology to evaluate optimal routes for PWD in urban settlements in the Kingdom of Saudi Arabia (KSA). A survey captured the preferences for 105 PWD, consisting of 37 powered wheelchair users, 62 manual wheelchair users, and 6 artificial limb users. The multi-criteria decision analysis evaluated the accessibility index for PWD based on four criteria: length, number of junctions, absence of footpath, and slope. This study revealed that manual wheelchair users prefer the length criterion, powered wheelchair users emphasized the absence of footpaths, and artificial limb users were concerned about slope. The result showed that only two routes out of ten showed medium, while those remaining exhibited low accessibility. Most routes were relatively long for people with disabilities, focusing on the need for public transportation with special arrangements in most small and medium-sized cities, like the study area of Hail and Qassim province of the KSA, to reduce the distance and travel time. The proposed framework provides valuable insights to route evaluation for persons with special needs in the KSA and elsewhere.

Who Were the Kazakh Jadids?

Abstract Located between the Volga-Ural region and Central Asia, where jadidism has been scrupulously studied over the past half century, the Kazakh steppe was nevertheless also an arena for the development of jadid thought, here, as elsewhere, characterized by the coexistence of modernist and Islamic reformist ideas. During the later imperial period figures identifying themselves, or subsequently identified as jadids were numerous. Jadids were active in urban commercial settlements, including Troitsk, Petropavlovsk, and Omsk, as well as in nomadic encampments on the steppe, and included Tatars, Bashkirs, and Kazakhs. The Kazakh case brings into question problems in defining jadidism itself. This is because figures identified in Kazakh Soviet, post-Soviet and in Western historiography as “intellectuals” or supposedly secular reformers also fit the definition of jadidism.

Digital-twin-based multi-scale simulation supports urban emergency management: a case study of urban epidemic transmission

ABSTRACT Improving emergency management capabilities is vital for sustainable cities. However, urban emergency management is a complex, giant system that interacts between urban virtual and real spaces, requiring simulation in the virtual space and feedback to the real space. The digital twin model can potentially play an important role in this process, but still faces significant challenges in terms of modeling, simulation, and visualization. In this study, we propose a digital-twin-based multi-scale simulation method and take epidemic transmission as a case study. First, an entity-oriented unified urban database integrating multi-source urban data was constructed as the digital twins of urban human settlements for emergency modeling. Then, a multi-scale urban emergency simulation method in 3D geographic environment was proposed to support emergency simulation for multi-level urban management units. Moreover, an adaptive fusion rendering of emergency information and 3D scene was proposed to support the refinement of emergency visualization. An experimental case study on epidemic risk estimation was conducted through thousands of outbreak scenarios. The results demonstrate that the proposed method can establish the digital twins of urban human settlements, where modeling, simulation, and visualization of emergency at multi-scales can be carried out, thus enhancing the efficacy and efficiency of emergency management.

Food Security Status and Associated Drivers Among Climate Migrant Households in Bangladesh: Insight From Urban Informal Settlements

ABSTRACTClimate migrants and their food accessibility are a pressing issue in Bangladesh that has not been adequately addressed in previous studies. This research aimed to examine the food security status and its associated drivers among climate migrant households' residing in urban informal settlements in Khulna city. This study was conducted in three selected wards (12, 21, and 31) known for their urban informal settlements and high concentrations of climate migrants. Data were collected on socioeconomic, demographic, COVID‐19 impacts, and the Household Food Insecurity Access Scale using an interview schedule. Descriptive (mean, standard deviation, and percentage) and inferential statistics (chi‐square test and binary logit model) were used to analyze the data. The study found a large portion of households to be food insecure (83.3%). Several socio‐demographic and economic issues, including the household head's education, occupation, and health, the number of working members, monthly income, savings, debt, and access to a safety net, were identified as significant drivers of food insecurity. Moreover, COVID‐19 impacts, considering loss of employment, income, and savings, shortages of daily needs, and price hikes on food items, were identified as the significant contributors to food insecurity. Responsible stakeholders may utilize the outcomes of this study to combat food insecurity and hunger among climate migrants residing in urban informal settlements through necessary policy measures.

A Review of Environmental Conditions between Planned and Unplanned Urbanization with Special Emphasis on Kalyani and Ranaghat Urban Areas

Urban settlements in India are generally classified as planned or unplanned as opposed to planned or unplanned urban areas due to land use and taking into account various factors including physical social and economic considerations and land use patterns. Rapid urban growth in India, mostly in an unplanned fashion, is currently a major problem. Urban growth occurs through replacement of vegetation, agricultural areas, wetlands, etc. This results in an unprecedented increase in heat, which dominates the microclimate of urban areas and creates an environmental crisis. Geospatial technology plays a unique role in planned and unplanned urban areas of West Bengal by monitoring spatio-temporal changes in urban heat by estimating land surface temperature and analyzing built-in indices of vegetation cover. It can be classified as NDVI and NDBI suggests that urban heat is controlled by surface character which is analyzed for proper planning for sustainability of urban areas

Bone and antler products from the Toretskoye urban settlement of the 15th century ad

Products made of bone and antler complement the characteristics of the material culture of the Toretskoye urban settlement, a major centre of crafts and international trade in the Kazan Khanate. In accordance with the general dating of the single-layer site, all items made of bone and antler have a reliable period of existence within the 15th century AD. Based on frequent numismatic material and other related context, the products receive the status of a chronological and, in some cases, ethnocultural reference point, and in terms of inventory and manufacturing techniques they represent products of urban production. No specialized bone-carving workshops have been found at the site; however, the presence of blanks and faulty products in the coppersmith and blacksmith workshops makes it possible to conclude that bone and antler processing was a related craft of complex production.

A GIS-Based Framework to Analyze the Behavior of Urban Greenery During Heatwaves Using Satellite Data

This work proposes a new unsupervised method to evaluate the behavior of urban green areas in the presence of heatwave scenarios by analyzing three indices extracted from satellite data: the Normalized Difference Vegetation Index (NDVI), the Normalized Difference Moisture Index (NDMI), and Land Surface Temperature (LST). The aim of this research is to analyze the behavior of urban vegetation types during heatwaves through the analysis of these three indices. To evaluate how these indices characterize urban green areas during heatwaves, an unsupervised classification method of the three indices is proposed that uses the Elbow method to determine the optimal number of classes and the Jenks classification algorithm. Each class is assigned a Gaussian fuzzy set and the green urban areas are classified using zonal statistics operators. The membership degree of the corresponding fuzzy set is calculated to assess the reliability of the classification. Finally, for each type of greenery, the frequencies of types of green areas belonging to NDVI, NDMI, and LST classes are analyzed to evaluate their behavior during heatwaves. The framework was tested in an urban area consisting of the city of Naples (Italy). The results show that some types of greenery, such as deciduous forests and olive groves, are more efficient, in terms of health status and cooling effect, than other types of urban green areas during heatwaves; they are classified with NDVI and NDMI values of mainly High and Medium High, and maximum LST values of Medium Low. Conversely, uncultivated areas show critical behaviors during heatwaves; they are classified with maximum NDVI and NDMI values of Medium Low and maximum LST values of Medium High. The research results represent a support to urban planners and local municipalities in designing effective strategies and nature-based solutions to deal with heat waves in urban settlements.

Energy Advantages and Thermodynamic Performance of Scheffler Receivers as Thermal Sources for Solar Thermal Power Generation

This article examines the prospects of Scheffler solar receivers integrated into renewable energy power plants for civil applications. This kind of solar receiver can offer satisfactory energetic performance with acceptable energy conversion efficiency when compared to other technologies to harness solar energy since the high-quality focal receiver can reduce heat losses also supposing great levels of evaporation temperature. In this research, energetic optimization and a broad assessment of Scheffler-type solar receivers are thoroughly conducted for variable sun radiation and considering a broad range of working conditions. To achieve this goal, thermodynamic optimization of the chief factors was attained via a numerical model which calculated the energy efficiency of the Scheffler solar receiver at part-load working conditions by computing all energy losses negatively affecting the heat exchange phase in the cavity receiver. The results obtained in this study show that the solar collector efficiencies of Scheffler receivers appear more promising than that of usual parabolic trough collectors; moreover, Scheffler receivers persisted with less sensitivity to reductions in solar radiation intensity. For these reasons, solar power systems based on Scheffler-type systems can be used from tens to hundreds of kW to ensure the energetic supply of small urban settlements with acceptable efficiency, optimistic investments, simple construction and reduced overall sizes.

Navigating the challenges of public transport and urban mobility in Thohoyandou, South Africa

Background: Transport systems are an essential feature of functional urban settlements. Yet, almost all of South Africa’s secondary cities and small towns lack a true public transportation system. Because of this, quasi-public, privately operated mini-bus taxis are the main form of transport for most urban residents. Thohoyandou, Limpopo, a town of over 70 000 people, is a typical South African town in this regard.Objectives: The purpose of this research was to understand passenger experiences of mini-bus taxis in Thohoyandou, Limpopo province, South Africa.Method: This study used semi-structured interviews to explore the mobility challenges faced by the residents of Thohoyandou.Results: This study revealed several negative aspects impacting passenger experiences. Passengers consistently reported concerns regarding driver’s behaviour that compromised safety and security. This included overloading of vehicles and disregard for traffic regulations. Passengers also highlighted the challenges posed by poor transport infrastructure and a lack of reliable service. Collectively, these factors contribute to limited mobility options, increased transportation costs and a reduced quality of life. Furthermore, the shortcomings of mini-bus taxi services disproportionately affect people with disability, who already face significant societal barriers, further marginalising them within the transportation system.Conclusion: The government should increase investment in transport infrastructure, the enforcement of traffic laws and better driver training. However, a strong government combined with much political will is required if passengers and safety are to be the main priorities of the mini-bus taxi industry.Contribution: This study highlights challenges faced by public transport users in Thohoyandou, where mini-bus taxis serve as the main mode of transport. The challenges experienced by transport users not only reduce their mobility but also contribute to marginalisation of vulnerable groups, especially people with disability.

Remarks on sustainable disposal and potential reuse of greywater in an informal urban settlement, Cape Town, South Africa

Background The disposal of greywater is a challenge for informal urban settlements that do not have a reticulation system to collect the wastewater they generate. Greywater, which includes domestic wastewater, represents a potential resource that can alleviate water stress if efficiently managed. This study aimed to provide sustainable disposal and potential reuse of greywater produced using informal settlements in Cape Town, South Africa. Greywater has the potential to contribute significantly to food security in such settlements by providing a source of both irrigation water and toilet flushing. Methods A combination of desktop research and interviews was employed to gather and analyze the data. A total of 69 questionnaires were administered in the study, and greywater management practices were investigated. Results The findings showed deficiencies in the sustainable disposal of greywater from households. To understand the volumes of greywater generated from a household, a model has been proposed in the study, as there has been a lack of focus on making predictions that quantify the volume of greywater recovered from these households. Conclusions In the context of sustainable development, water management, and considering the scarcity of water resources, particularly in semi-arid regions, the use of treated greywater is an alternative method that can reduce the burden of withdrawals. The study has demonstrated that socio-economic status and education level has reciprocal outcomes on the communities’ understanding of environmental issues. Eliminating inappropriate disposal and providing means to sustainable reuse of greywater effluent is the key.
