The Rivers State University campus in Portharcourt is one of the university campuses in the city of Portharcourt, Nigeria covering over 21 square kilometers and housing a variety of academic, residential, administrative and other support buildings. The University Campus has seen significant transformation in recent years, including the rehabilitation of old facilities, the construction of new academic facilities and the most recent update on the creation of new collages, faculties and departments. The current view of the transformations done within the University Campus is missing from several available maps of the university. Numerous facilities have been constructed on the University Campus that are not represented on these maps as well as the qualities associated with these facilities. Existing information on the various landscapes on the map is outdated and it needs to be streamlined in light of recent changes to the University's facilities and departments. This research article aims to demonstrate the effectiveness of unmanned aerial systems (UAS) in geospatial data collection for physical planning and mapping of infrastructures at the Rivers State University Port Harcourt campus by developing a UAS-based digital map and tour guide for RSU's main campus covering all collages, faculties and departments and this offers visitors, staff and students with location and attribute information within the campus.Methodologically, Unmanned Aerial Vehicles were deployed to obtain current visible images of the campus following the growth and increasing infrastructural development. At a flying height of 76.2m (250 ft), a DJI Phantom 4 Pro UAS equipped with a 20-megapixel visible camera was flown around the campus, generating imagery with 1.69cm spatial resolution per pixel. To obtain 3D modeling capabilities, visible imagery was acquired using the flight-planning software DroneDeploy with a near nadir angle and 75 percent front and side overlap.Vertical positions were linked to the World Geodetic System 1984 and horizontal positions to the 1984 World Geodetic Datum universal transverse Mercator (UTM) (WGS 84). To match the UAS data, GCPs were transformed to UTM zone 32 north.Finally, dense point clouds, DSM, and an orthomosaic which is a geometrically corrected aerial image that provides an accurate representation of an area and can be used to determine true distances, were among the UAS-derived deliverables.Keywords; UAS, Geospatial, Acquisition, Orthophoto, Mosaic, Flying –Height.

This qualitative study argues that occupant involvement in housing design and construction process should lead to more appropriate buildings that can sustain their usefulness with minimal changes. It documents the design of a house in Bushbuckridge, Mpumalanga, South Africa that uses Open Building (OB) principles so that the house adapts to the changing needs of the family and maintains its intergenerational value. This project centres the occupant in the design and construction process and considers the house flexible and conceived by many authors. Based on this worldview, we use the following tools: a literature review on OB, an OB analysis of low-cost housing, and analysis of the design project. We compare low-cost housing projects using four OB principles: how the project involves the occupant’s agency to build; how the project separates its elements to facilitate this agency; whether the project focuses on providing a housing product, or a housing process; and, how sustainably the delivered structure can accommodate the occupant’s current and future construction. The paper illustrates these OB principles in the design of a low-cost, rural house project in Bushbuckridge to show that they also have value for the architecture at a small scale, and how a house can be designed to ensure that it adapts to the changing needs and creativity of the occupant. The paper concludes with the implications that OB principles have for the design process. The process no longer consists of a simple sequence that separated design and construction and ends with a housing product. Rather, the design and construction focus on delivering a building process that the occupant can take ownership of a sustain intergenerationally.

Recently, the direct causal relationship between the built environment and well-being has been shown to affect the quality of life as well as the performance of the urban environment. While it is often difficult to establish, the urban built environment plays a major role in shaping the way people act inside it. (Thwaites, Kevin, et al., 2016) While urbanisation takes place in a transforming society, societal development leaves its signature in urban spaces. When industries and development plans decline in some parts of the city, especially those with archaeological value, those parts will have been abandoned due to migration. Urban pockets or gaps inside the built environment are left behind to suffer from informality, deterioration, and increasing crime and unemployment rates. The aim of that research is to find some possible solutions in the direction of improving those public abandoned spaces that accommodate dangerous buildings, high rates of unemployment and unsafe urban areas in the regional range of Meet-Ghamr, Dakhlia governorate. (Aggnieszka Lisowska, 2017). The targeted area of the study is "minaret el Amir Hamaad" in Meet-Ghamr, Dakahleia, Egypt, one of the most important archaeological sites in the Islamic heritage of Dakhlia governorate, which is well known for its unique mosques and mosque minarets.

Loreto, the largest Amazonian region in Peru, is home to more than 200,000 inhabitants that live in traditional riverside rural communities adapted to an amphibious lifestyle, with houses that rise or float on the river in times of flooding and perch on the dried riverbed in low water times. Nevertheless, these amphibious communities are not exclusive to rural areas. Iquitos, the largest city of Loreto, is surrounded by alluvial plains, where more than 90,000 people live on the water and bring a rich social, cultural, and environmental vibrancy to the regions. However, poor infrastructure conditions and limited resources in this communities affect the ecosystem and the population's health. The objective of this qualitative study was to understand the physical, sociocultural, and environmental conditions in which these amphibious communities live and identify the political, legal, and cultural barriers that prevent their healthy urban development. Data collection was conducted through semi-structured interviews, surveys, and observation of physical and environmental conditions. The results suggest conflicts in the formalization processes of theses informal communities, from administrative and legal aspects to a limited definition of habitable territory. We identified the benefits of the current urban-architectural conditions of these communities, whose housing typologies, adapted to the seasonal change of the rivers, may provide a alternative model to adapt with resilience to the impacts of climate change and sea level rise. We also identified challenges in sanitation, accessibility, public space, and strengthe of community networks, as well as challenges in the response of the government whose proposals for relocation of the amphibious communities have not fully considered these communities' economic, social, and cultural values.

This paper investigates opportunities to connect divided cities by analysing ways in which occupation practices operate alongside, subvert and potentially transform historic, and presently developing urban infrastructure divisions in Tshwane’s eastern urban region. Through a critical theory lens existing and perpetuating conditions of infrastructural segregation are examined in order to understand scenarios through which built environments, as assemblages, maintain conditions of extreme inequality and power. In this respect, urban spatial research projects, analysing formal and informal settlement patterns are presented. The projects form part of an architecture design lead research studio that focuses on discovering alternative scenarios for urban environments by examining existing infrastructure barriers, and unpacking methods for the transformation of segregative systemic forms. Extracts of the projects are presented as case studies with a focus on areas around Mamelodi east and Moreleta Park in rapidly growing parts of Tshwane. These projects demonstrate conditions through which urban divisions of scarcity are established and constructed along infrastructure development zones in the region. They also raise key spatial questions pertaining to inequality and the role of capital investment in its perpetuation. The second part of the project involves socio-spatial methods of mapping self-build situations occurring alongside hard infrastructure zones in the region. The studies focus on the composition of building fabrics that actively attempt to circumvent issues of scarcity and unequal access to material and social infrastructures. Through the establishment of physical interfaces, people form modes of operation despite extreme resource limitations. The project aims to identify alternative ways of reading territorialised urban infrastructure assemblages by examining critical zones of urban occupation. While the examples expose many of the volatile situations that the urban majority experience on a perpetual basis, the primary aim is to reveal - from the everyday – urban spatial emergence and methods of coding and mapping these emergences towards an adaptive, reparative and transformative approach to divided cities.

The Neighborhood Impact Assessment (NIA) [1]is an important instrument of the Brazilian Urban Policy enacted in the City Statute, Federal Law 10.257/2001. Considered by the national academic literature as a relevant instrument for local urban environmental management. However, in Brazil, the understanding that the environmental and the urban are part of the same context is not yet a reality within the local public administration sectors, with a deep disconnection of management and governance between the urban and environmental departments. The objective of this work was to analyze the application of NIA in medium-sized cities in the state of São Paulo and to evaluate its contribution to the local urban environmental management of these cities. We also intend to evaluate the NIA integration with other sectors of local public management such as the environment, urban mobility, social housing, etc. As a methodology, we used NIA Process Components, verifying the absence or presence in the urban laws of four (04) medium-sized cities in the state of São Paulo. We also interviewed civil servants from the environmental and urban sectors, supplementing information that was absent in laws and official documents. The results reveal that most municipalities do not have a specific law that regulates the NIA, and Master Plans, Land Use and Occupation Law regulate this instrument. Civil servants emphasize the weaknesses and strengths of the instruments. As potentialities of this instrument, they observed public participation, increased state control in environmentally sensitive areas, greater urban-environmental compensation mechanisms, and so on. Weaknesses signalize were: conflicts involving urban land subdivision, interference of the real estate market in the use and occupation of urban land, changes in the Master Plans by the city councilman aiming to meet the interests of private financial capital. The four cities, which are part of the Case Studies, have not yet effectively incorporated elements of climate change in their local governance. Issues related to social housing, expansion of slums, occupation of protected environmental areas by poor populations are still the most urgent priorities in these cities, as well as in many Latin American cities. The improvement and advancement of the articulation of the urban and environmental sectors in Brazilian cities must require thinking about better scientific methodological and governmental improvements. [1] Brazilian authors often use the terminology in English “Neighborhood Impact Study”. However, we chose to use “Neighborhood Impact Assessment” according to (Abiko & Barreiros, 2014) to facilitate the understanding of the instrument for the international audience, as it has similarities with the Impact Assessment. However, in Brazil, the NIA is known as the “Estudo de Impacto de Vizinhança”.
社区影响评估(NIA)[1]是巴西城市政策的重要工具，在城市法规(联邦法律10.257/2001)中颁布。被国家学术文献认为是地方城市环境管理的相关工具。然而，在巴西，地方公共行政部门还没有认识到环境和城市是同一背景的一部分，城市部门和环境部门之间的管理和施政严重脱节。这项工作的目的是分析NIA在圣保罗州中型城市的应用，并评估其对这些城市当地城市环境管理的贡献。我们还打算评估NIA与其他地方公共管理部门(如环境、城市交通、社会住房等)的整合情况。作为一种方法，我们使用NIA流程组件，验证了圣保罗州四个(04个)中型城市的城市法律中是否存在。我们还采访了来自环境和城市部门的公务员，补充了法律和官方文件中缺失的信息。结果表明，大多数市政当局没有具体的法律来规范NIA，总体规划、土地使用和占用法规范了这一工具。公务员强调这些工具的优缺点。作为这一工具的潜力，他们观察到公众参与、加强国家对环境敏感地区的控制、更大的城市-环境补偿机制等等。弱点信号是:涉及城市土地细分的冲突，房地产市场对城市土地使用和占用的干预，市议员为满足私人金融资本的利益而修改总体规划。作为案例研究的一部分，这四个城市尚未有效地将气候变化因素纳入其地方治理。与社会住房、贫民窟扩大、贫穷人口占领受保护的环境地区有关的问题仍然是这些城市以及许多拉丁美洲城市最紧迫的优先事项。要改善和促进巴西城市中城市和环境部门的联系，就必须考虑更好的科学方法和政府改进。巴西作家经常使用英语术语“Neighborhood Impact Study”。然而，根据(Abiko & Barreiros, 2014)，我们选择使用“邻里影响评估”，以促进国际观众对该工具的理解，因为它与影响评估有相似之处。然而，在巴西，NIA被称为“Estudo de Impacto de vizinhana”。

Urban intensification seems to be a growing trend, especially in the context of severe land scarcity. Brownfields offer great potential in meeting the increasing demand for housing in major cities worldwide. Redevelopment projects appear to provide immediate solutions to housing shortages that are being experienced due to population pressures in large metropolitan areas. The paper explores the range of factors that property developers need to consider in their decision-making process when assessing the viability of brownfield redevelopments. This research, which employed a comparative case study approach, and examined two brownfield redevelopments in Auckland, focused on the economic, social, and environmental criteria that were utilised in the decision-making process. Document analysis of the two case studies, site observations, and semi-structured interviews with the property developers were the main data collection methods. The results suggested that the economic aspects of a brownfield redevelopment are the most important criteria that developers consider during the feasibility assessment of proposed projects. Projects that offer the potential for quick investment returns for all stakeholders are the preferred choice for developers. Brownfield redevelopments offer significant potential for invigorating local areas through urban intensification which boosts local businesses and encourages community revitalisation. The environmental concerns appear to be the lowest priority and little consideration is given to reducing the environmental impacts or incorporating green building practices in the new developments. A major shift from a purely economic focus toward a comprehensive environmental approach to new developments is needed to ensure the sustainable development of cities.

Coastal communities will be more vulnerable to floods in low-lying areas and seawater inundation as the sea level rises. Users will have to take a detour to use alternate roads while the vulnerable roads are closed, increasing travel time. A large amount of literature has been focused on addressing climate change and sea-level rise impacts, vulnerability, economic evaluation, and adaptation. However, few studies have been conducted to study the impacts of population dynamics due to sea level rise within future transportation network modeling. This study aims to identify the future transportation infrastructure in the 2035 model that is vulnerable to a two-foot sea level rise in the Tampa Bay Region, Florida. The impacts of these changes have been considered within three different relocation scenarios for the affected population in the inundated zones. This analysis uses the two-foot Mean Higher High-Level water surface data and the digital elevation data provided by NOAA for 2035. The findings of this study reveal how different sea level rise scenarios could affect the future estimates of the transportation system and could potentially inform future transportation planning decisions. The analysis found that approximately 358 lane miles of highway links will be inundated. Moreover, the number of trips produced, and the amount of congestion generated with each scenario were dependent on the population and employment relocation. The key recommendation of this research is to incorporate the potential impacts of population relocation due to sea level rise into transportation modeling. Generally, different scenarios for relocating population and employment generate new traffic demands, which could result in traffic congestion. Thus, transportation planners should simulate future sea level rise scenarios and evaluate their impact on the current transportation system. Findings from this study could help transportation planners and decision-makers identify the locations and transportation facilities that are most vulnerable to rising sea levels, allowing them to make more informed decisions about adaptation planning.

Gomaa","doi":"10.21625/essd.v7i2.884","DOIUrl":"https://doi.org/10.21625/essd.v7i2.884","url":null,"abstract":"Coastal communities will be more vulnerable to floods in low-lying areas and seawater inundation as the sea level rises. Users will have to take a detour to use alternate roads while the vulnerable roads are closed, increasing travel time. A large amount of literature has been focused on addressing climate change and sea-level rise impacts, vulnerability, economic evaluation, and adaptation. However, few studies have been conducted to study the impacts of population dynamics due to sea level rise within future transportation network modeling. This study aims to identify the future transportation infrastructure in the 2035 model that is vulnerable to a two-foot sea level rise in the Tampa Bay Region, Florida. The impacts of these changes have been considered within three different relocation scenarios for the affected population in the inundated zones. This analysis uses the two-foot Mean Higher High-Level water surface data and the digital elevation data provided by NOAA for 2035. The findings of this study reveal how different sea level rise scenarios could affect the future estimates of the transportation system and could potentially inform future transportation planning decisions. The analysis found that approximately 358 lane miles of highway links will be inundated. Moreover, the number of trips produced, and the amount of congestion generated with each scenario were dependent on the population and employment relocation. The key recommendation of this research is to incorporate the potential impacts of population relocation due to sea level rise into transportation modeling. Generally, different scenarios for relocating population and employment generate new traffic demands, which could result in traffic congestion. Thus, transportation planners should simulate future sea level rise scenarios and evaluate their impact on the current transportation system.

Chaoshan vernacular house is an important branch of Lingnan traditional houses in South China, with a long architectural history and excellent climate responsiveness to the hot-humid climate. The modern rural houses learn the traditional experiences mainly in the form but fail to inherit the climate-responsive design and wisdom of the traditional houses. This study took the widely distributed Xiashanhu houses in Chaoshan as the object, generated 128 Xishanhu parametric models by combinations of various parameters on design factors of building, opening, shading, construction, and street layout, and investigated the climate-responsive design techniques by using the parametric methods. The results show that the hall width, room width, cornice height, orientation, and wall construction are the key climate-responsive design factors oriented towards thermal performance of Xiashanhu houses. The optimized designs are: the smaller hall width (4.05m，4.32m，4.59m), the smaller room width (2.7m，2.97m，3.24m), the larger cornice height (4.92m，5.1m), the orientation ranged from 30° north by west to 30° north by east, and the brick and concrete wall. The rationality and validity were verified by applying the optimized climate-responsive designs to the re-construction of a new rural house. Compared to the original case, the thermal performance is significantly improved by 5.18-9.98%. A detailed discussion was also provided on considering the actual situation and needs of the modern buildings in the process of "using the past for the present." This study is believed to provide valuable references for the research and modern applications of climate-responsive designs of traditional vernacular houses. It also contributes to the preservation of architectural and cultural regional characters and the inheritance of architectural climate responsiveness in contemporary times.

Cities and towns are the social constructs in regional settings. They physically manifest and exist as power centres through various layers of culture, economy, politics, and religion. There was a symbiotic relationship between the ‘setting’ and the ‘construct’ in the past. With time and advent of technology, haphazard developments led to degradation of ecological systems and have become a confronted affair. Global warming, its adverse effects and the constant references to the words ‘sustainability’ and ‘resilience’ pose questions on the existing planning models. Small towns experiencing a tremendous pressure of urbanisation and rich in natural resources, coherence and identity are fast changing. An indispensable change in the planning models is necessary to mitigate this existential crisis and condition the emerging urbanism in small towns sustainably. This paper unearths the role and possibilities of bioregional planning as a sustainable urban development paradigm and suggests few indicative parameters for envisioning bioregionalism in small towns.
