<![CDATA[One of the negative effects of the high rate and pace of urbanisation in developing countries is the decay of urban centres. While this decay has eaten deep into the fabric of these settlements turning them into urban slums and ghettoes with poor infrastructure, the effects of the decay are multifarious. Despite the fact that the economy is the “life-wire” of urban centres, its untold downturn consequent upon urban decay is unimaginable because of the relationship that exists between environmental quality and economic growth. This calls for a proactive approach called urban renewal towards the creation of successful urban places. This paper, therefore, reviews urban renewal strategies and their implications on economic growth with a particular focus on Ondo State, Nigeria towards identifying the means of enhancing the sustainability of its economic proceeds. The study relied on secondary information sources and discovered that appropriate urban renewal strategies yields corresponding economic growth. The paper asserts that the urban renewal fit achieved in the state during the period 2009 to 2012 can be replicated in other states in Nigeria if similar political willpower is available. The paper recommends the participation of the public combined with appropriate strategies in urban renewal schemes for the best result and argues in conclusion that urban renewal is the only feasible solution to the current dwindling economic sector in Nigeria and other developing economies.]]>

<![CDATA[Considering the three-dimensional process of sustainability (physical- economical and social), the aim of conservation for making historic urban environment sustainable should be matched with these dimensions. Therefore, earlier conservation policies have progressed from a simple and restrictive concern with preservation to an increased concern for revitalization and enhancement. This means a physical revitalization may be short-lived and un-sustained. Within the process of revitalization, historic environments become the main locations of gentrification induced by urban revitalization which may involve social cost. Accordingly, this paper develops theoretical concepts on “sustainability in historic urban environment” with a particular emphasis on a social issue in terms of gentrification. Also with the result derived from theoretical parts concludes that social changes through gentrification contribute to sustaining the historic environments.]]>

<![CDATA[Urban stormwater lakes in cold regions are ice-covered for substantial parts of the winter. It has long been considered that the ice-covered period is the “dormant season,” during which ecological processes are inactive. However, little is known about this period due to the historical focus on the open-water season. Recent pioneering research on ice-covered natural lakes has suggested that some critical ecological processes play out on the ice. The objective of this study was to investigate the active processes in ice-covered stormwater lakes. Data collected during a two-year field measurement program at a stormwater lake located in Edmonton, Alberta, Canada were analyzed. The lake was covered by ice from November to mid-April of the following year. The mean value of chlorophyll-a during the ice-covered period was 22.09% of the mean value for the open-water season, suggesting that primary productivity under the ice can be important. Nitrogen and phosphorus were remarkably higher during the ice-covered period, while dissolved organic carbon showed little seasonal variation. Under ice-covered conditions, the total phosphorus was the major nutrient controlling the ratio of total nitrogen to total phosphorus, and a significant positive correlation existed between total phosphorus and chlorophyll-a when the ratio was smaller than 10. The results provide preliminary evidence of the critical nutrient processes in Stormwater Lake during the ice-covered period.]]>

<![CDATA[The significance of neighbourhood in hosting a group of dwellings units and possessing adequate communal facilities could not be overemphasized in the study of people and place relationships. There are two main objectives of this study: (i) to study the neighbourhood’s associated challenges through the size, growth, and land use distribution, and (ii) to investigate the perceived inhabitants’ activities pattern within the neighbourhood. The objectives are explored through a morphological and GIS-based land use analysis of a rural neighbourhood in South-west, Nigeria. The town is studied in three transformation phases, dating back to five decades using ArcGIS version 10.3. The 1st phase spanned between the year 1910 to 1959, while the 2nd and 3rd phases ran through the year 1960 to 1999, and the year 2000 to 2015 respectively. The exploration in this study is to document the diverse neighbourhood challenges, features, and prospects, which remain uninvestigated in the case study area for the past years. In conclusion, human historical and social influences play a significant role in ameliorating the challenges associated with the spatial developments of the settlements. The implication of the study becomes vital to the major stakeholders and professionals in the built environment on the significance of enhancing the sustainable communities in Nigeria.]]>

<![CDATA[Northern Iraq as part of Iraq, has been witnessed a great population increment last few decades. However, housing stress in Northern Iraq has risen due to that. Environmental, economic and social sustainability became crucial in the movement towards a more effective built environment and community nowadays. This research seeks to evaluate the presence of sustainability aspects (environmental, economic, and social) in the housing sector, which makes them acquired and affordable for low-income earners in Northern Iraq. Housing projects as case studies were investigated in Erbil, the capital of Northern Iraq. The research examined, the presence of sustainability aspects. Field observations checklist has been prepared based on the theoretical analysis through literature review and applied to collect data on the case studies. The results demonstrated that applying the aspects of sustainability for the buildings is weak and not clearly familiar in Northern Iraq. The study concluded that the housing projects focusing on the case study not sustainable. The findings show that the application of sustainable principles in the housing projects in Northern Iraq is very weak. It is highly recommended to achieve sustainability, because it is a significant way to produce acquired and affordable housing and overcome the housing problems, socially, environmentally and economically. The recommendations have been suggested to formulate new ways of implementing sustainable principles in the housing sector to overcome housing stress in Northern Iraq.]]>

<![CDATA[In this article, the study assessed the domestication process of humankind within the frame of urbanization and power accumulation. Within this framework, by giving various examples from chicken farms. The study expresses the author’s opinions on the analogy of the “liberated human beings” in cities and the “free-range” chickens in farms. It has also been tried to explain how a city acts as a human farm. Cities are governed by the ones holding power similar to the farms are ruled by farmers and humans during their history of civilization have lost their right of deciding on their lives and fates against this power as the domesticated animals in farms. It is necessary to give up these cities which are models of life organizations from the Old and the Middle Ages. Models of settlements which became even more inhumane as results of modernization and neo-liberalization strategies. The study revealed that With the scientific and technologic improvements and the developments of in science and humanities, it is possible to easily replace the city model of communal life with a better one -The one in which people can be more free and happy and will give more life to the earth and contribute to the aliveness within it.]]>

<![CDATA[Modern architecture developed more than a century ago to find solutions suitable to solve the new concerns of the industrial revolution that changed the social idea of the world in all aspects. Bauhaus school which established by Walter Gropius in 1919 adopted too many principles and ideas that were totally new to the architectural concept and theory at that time; their principles started from Simplicity, Angularity, Abstraction, Consistency, Unity, Organization, Economy, Subtlety, Continuity, Regularity, and Sharpness. Those principles affected the architectural world and found its way through many applications in different parts of the world. The unlimited space or the international space that had a significant influence on the architecture space and form as well as the introduction of the new material, the anti- decorating, and Platonic forms had worked to reconstruct the architecture in the world. Cyprus as an island close to the sources of the movement got the influence from the modern movement. The study will concentrate on Efruz Housing which designed by Ahmet Vural, who developed the project in the 60th of the last century. The aim of the research is to find the relationship and effects of Bauhaus school in Cyprus through studying and analyzing some of Ahmet Vural works. The methodology will depend on a comparison with the traditional housing that preceded Mr. Vural work and how the Modernism changed the main features of the housing on the Island.]]>

<![CDATA[The most critical factors in the acceleration of climate and environmental changes are related to industrial development and consequently to an increase in the demand for electricity. Looking for measures that minimize impacts on the environment, alternative energy sources are gaining more and more space in the Brazilian energy matrix. Brazil presents a great solar potential for the generation of electric energy, so the knowledge of solar radiation and its characteristics are fundamental for the study of energy use. Due to the above, this article aims to verify the climatic variability corresponding to the variations in solar radiation patterns, in the face of climate change scenarios. The database used in this research is part of the Phase 5 Intercomparison of Matching Models (CMIP5). It is important, first of all, to determine its availability in order to enable the use of solar radiation as a source of energy in a given location and/or region. The climatic projections, based on the pessimistic scenario, in a 75-year period (2026-2100) showed a fall in solar radiation in all of Rio Grande do Sul, reaching 12% in the eastern region of the state. A concern with the factors that influence the pessimistic perspectives of this scenario, as it may affect a possible production of electric energy from solar radiation.]]>

<![CDATA[An exergy analysis has been performed to determine the potential for useful work in a latent heat storage system with phase change material (PCM) for a flat-plate solar collector. Commercial paraffin wax is used as PCM to store and release energy in the solid-liquid transformation; this material is located in metal containers under the absorber plate on the bottom insulation of the collector. The exergy analysis is performed in outdoor conditions for days of the low, medium and high radiation taken from October 2016 to March 2017 at Barranquilla city (latitude: 10º 59' 16" N, longitude: 74º 47' 20" O, Colombia). The system is evaluated throughout charge and discharge periods. The energy and exergy balance equations based on the first and second law of thermodynamics is formulated and solved for each element of the collector system as well as for the PCM. Results obtained show the energy distribution and energetic destruction for each system component and its variation as a time function. It was observed that the average energy and energetic efficiency are 28.7 %, 13.2 % for of low radiation days. 26.9%, 20.56% for of medium radiation days, and 23.2%, 18.6% for of high radiation days, respectively. Results of the analysis are shown in detail in the present paper.]]>

<![CDATA[The hydroelectric plants are first in the Brazilian energy matrix, so irregularities in the rainfall regime can affect the energy generation, thus evidencing the need to know the rainfall distribution in the studied area. This work aimed to evaluate possible analysis of the impacts of climate change on the rainfall regime in the Machadinho hydroelectric region. For the research development, the IPCC-AR5 pessimistic scenario was used, representing a scenario with a continuous population growth and high carbon dioxide emissions. From the historical series and organized projections, precipitation anomalies were calculated. Analyzing the difference between the average of the month and the climatological normal, it was inferred that the model used presented a positive trend for precipitation in the period from 2026 - 2100, projecting anomalies between 25 and 200 mm per month. A greater amplitude is observed in the precipitation of 2076-2100, indicating an increase in the occurrence of extreme events of precipitation, mainly in the spring period. Considering that the rains in the Machadinho hydroelectric region are increasing in the scenarios analyzed, the average water level in the reservoir of the plant tends to increase.]]>
