“…Out of the 43% that have some soft landscape planted within the church premise, a very few were seen to have used these plants to direct traffic, restrict vehicular movement and deter intrusion while some others used it to soften the hard physical security elements. Most of the churches that planted soft landscape within were basically for beautification of the church as agreed by [15,21]. Credit should be given to churches like RCCG at Tunga West as seen in Plate 2…”

“…Adaptation simply refers to the different measures that should be taken to reduce the adverse impact of global warming on human life and the environment of which the buildings inhabited by humans. Examples of the adaptation methods include: changing the cropping patterns; stopping further development on wetlands, flood plains, and close to sea level; developing crops that are resistant to drought, heat and salt; strengthening public health and environmental engineering defense against diseases; designing and building new water projects for flood control and drought management; construction of dykes and storm surge barrier against sea level rise [14,15]. On the other hand, adaptation involves coping with climatic change, taking measures to reduce the negative effects, or exploit the positive ones by making appropriate adjustments.…”

Nigeria is faced with several risks ranging from problems of climate change to security challenges and this is not limited to a specific aspect of the built environment as all buildings and environment are affected. The places of worship are greatly affected in terms of security which affects the disposition of Christians during worship at churches. Many of the studied churches were seen to have made use of landscape elements but these were not placed with the aim of using them to deter intrusion as in the case of security but rather for beautifying the church. The challenge for architects and church administrator is how to cope with challenges of security and climate change. This paper examines landscaping as a catalyst for deterring intrusion of threats passively and enhancing climate adaptation in church environment in Nigeria. The research method adopted for this study is the descriptive survey method by collecting qualitative and quantitative data. The results were analyzed using descriptive tools in SPSS and are presented in tables and charts while the pictures are presented in plates. The study reveals that it is possible to achieve passive security and solve some climatic challenges in church environment using soft landscape elements. The paper is concluded by determining the aspects of the building where the architect can infuse the specific landscape elements to achieve the aim of the paper. It further states the type of landscape elements that could be used to achieve the aim of the study hence developing a responsive building design scheme. http://dx.doi.org/10.4314/njt.v36i1.2

“…Under the environment category, there were cases of desert encroachment, loss of wetlands, loss of biota resources, and rapid reduction in the amount of surface water (Ebele and Emodi, 2016;Akande et al, 2017;Abdulkadir 2017). Other forms of impacts on the environment reported were; effects on infrastructures (Adegoke and Sojobi, 2015), built environment (Ede et al, 2013;Ezeabasili and Okonkwo, 2013), flooding (Adeoye et al, 2009), coastal erosion and vegetation change (Akinro et al, 2008). Climate change also resulted in freshwater scarcity (Audu et al, 2013) and affected rural water supply (Adebo and Sekumade, 2013), as well as soil degradation in the country (Usman et al, 2013).…”

“…In the future, buildings with reduced carbon dioxide emissions, improved ventilation, and those that provide a highquality indoor environment, are imperative towards a sustainable built environment (Celadyn, 2018;Sojobi and Zayed, 2021). In addition, weather data is also required to evaluate how water delivery systems and urban drainage would function in future (Ezeabasili and Okonkwo, 2013).…”

There is evidence that Nigeria is already experiencing environmental challenges attributed to climate change (CC) and its impacts. This has clearly highlighted the need for knowledge-based strategies to help plan adequate mitigation and adaptation measures for the country. One of the basic requirements to ensure such strategies is the development of a database of national CC research. This will aid in the assessment of past and present scientific publications from which directions for future study can be mapped. The present study used standard, systematic, and bibliographic literature reviews to analyse the trend, focus, spatial variability, and effectiveness of published research on CC impacts in Nigeria. Four thematic areas of CC impact research were defined: Agriculture, Environment, Human and Multi-disciplinary study. A total of 701 articles were found to be relevant and the review shows that CC impacts and adaptations in the literature vary across research categories and locations. The period between 2011 (68 studies) and 2015 (80 studies) showed a tremendous rise in CC impact research with a peak in 2014 (84 studies). Studies in the agriculture category had the highest publications in 23 States of Nigeria. The review revealed three research gaps: (1) lack of research that investigated the magnitude of present and potential future impacts in the aquatic environment (2) little attention on CC impacts and adaptation in the Northern regions of Nigeria (3) absence of study investigating the effects of multiple variables of CC at the same time. The findings suggest that it would be useful to advance CC research in Nigeria beyond perceptive approaches to more quantitative ones. This is particularly important for highly vulnerable animals, crops, locations, and for better planning of adaptation strategies.

“…Consequently, Schramn and Dries [2] argued that flooding is the topmost natural disaster which rather than declining, is becoming a greater threat. Every time and anywhere flooding occurs, lots of damages are incurred and these damages range from considerable loss of lives, economic loses, destruction of built and natural environment, disruption of local institution to livelihood, and disempowering of the local community thereby hindering nations from achieving sustainable development [3]. These damages are associated with environmental, economic, social, and demographic and psychological dimensions.…”

Flood remains one of the most common natural disasters. Its rate of occurrence and the associated destructive tendency are on a rising scale across the globe. Flood risk may increase due to human activities. It could also decrease by appropriate flood management and planning. However, this requires upgraded and newly generated reliable and up to date floodplain and flood vulnerability maps. Hence, this study analysed the Niger-Benue river flood risk and vulnerability of 256 communities in Kogi State. The aim is to generate reliable up to date flood vulnerability maps that categorises the communities into different vulnerability zones and identify likely locations for erecting flood shelter/refugee camps during flood events in the State. Shuttle Radar Topography Mission (STRM) Digital Elevation Datasets, the spatial location of 256 communities, shapefiles of Kogi State’s administrative boundaries and Niger-Benue river basin were among the datasets acquired for the study. The Digital Elevation Model (DEM) of the study area was created to depict topography and the heights of each component of the terrain. Also, a 3km buffer distance was created around the Niger-Benue river and four vulnerability zones were defined based on the terrain and proximity components of each community. Furthermore, choropleth maps were generated for each vulnerability zone based on the number of communities per Local Government Area (LGA). Findings of this study revealed that out of the 256 sampled communities, 161 representing 62.89% are exposed to varying degrees of vulnerability due to Niger-Benue flooding. Out of these, 33 (12.89%) are highly vulnerable, whereas each of the vulnerable (64) and marginally vulnerable (64) communities accounted for 25%. The rest 37.11% constituted the not vulnerable communities (95). Out of the highly vulnerable communities, 27.27% accounted for those located on river banks and 72.73% for those located within a 3km distance from the river. The majority of the riverbank communities were found in Kogi, Lokoja and Ajaokuta LGAs. Igalamela Odolu, Kogi, Ofu and Bassa were among the LGAs with a high number of vulnerable communities. The not vulnerable communities were mostly located around the Agbaja Plateau and Okoro-Agbo hills in Ijumu, Kabba/Bunu and Yaba East LGAs. It was concluded that the 9 communities (Ajaokuta, Eroko, Iche, Jamata, Numai, Okume, Agodo, Denbor and Gunji Twaki) located on river banks are exposed to the highest level of flood risk and invariably, the devastating impact of flood in Kogi State. Most communities in Ijumu, Kabba/Bunu and Yaba West LGAs are less likely to be affected by Niger-Benue River flooding. It is therefore recommended that communities within the highly vulnerable zones, beginning with the 9 located on river banks should be relocated to higher terrains. Also, future settlement development should be discouraged in the zone by the collaborative efforts of the State and LGA authorities. Further studies should be conducted around Ijumu LGA in view of identifying the most suitable locations for possible flood shelter/refugee camp development in the study area.
