INTRODUCTION
Nigeria's sustainable growth requires us to address the global issue of climate change as soon as possible(Anabaraonye, Okafor & Hope, 2018). "Adjustment in natural or human systems to a new or changing environment" is the definition of climate change adaptation given by the Intergovernmental Panel on Climate Change (IPCC).The term "adaptation to climate change" describes modifications made to natural or human systems in reaction to existing or predicted climatic stimuli or their consequences, with the goal of minimising harm or taking advantage of advantageous circumstances. One can distinguish between several forms of adaptation, such as planned and autonomous adaptation, private and public adaptation, and anticipatory and reactive adaptation (IPCC, 2001). Nigeria is severely affected by climate change, and planting trees has been identified as one method of coping with the effects of the shift for sustainable development in Nigeria(Anabaraonye, Okafor, Ewa & Anukwonke, 2021). Building projects create the much-needed roads, homes, train stations, airports, and other infrastructure. These are admirable, well-intentioned advances, but their sustainability must be considered.In the context of these kinds of advancements, sustainability refers to addressing the needs of the environment, future generations, and the present.
The Nigerian construction industry has demonstrated over time that it can boost the country's economy by delivering infrastructure projects on schedule and with significant economic benefits(Oke et al., 2018The sector's expansion has greatly increased the country's GDP, generating a large amount of jobs and possibilities for the populace (Saka and Lowe, 2010). On the other hand, it has also been discovered that its operations harm the environment in other ways, such as through the creation of trash and water scarcity(Toriola Coker et al., 2021). Without reducing it via sustainable methods within the building sector, these negative consequences on construction cannot go on. Given its effects on the environment, the building sector has been a crucial one for sustainable growth (Ofori, 2007). As a result, the construction of buildings has undergone a significant shift due to sustainable development, offering superior financial standing to promote social well-being in a conservative setting(Davies &Davies, 2017). These days, building must include these elements as sustainability and environmental friendliness go hand in hand(Aigbavboa et al., 2017).
The purpose of sustainable construction is seen to be a comprehensive concept aiming towards rebuilding and harmonising the environment and the economy, according to Agenda 21 for Sustainable Construction Industry in Emerging Nations(Du Plessis, 2002). The idea was to use resources more efficiently and have a less environmental effect; in contrast, the first method was more focused on technical problems than social economies(Shafii et al., 2006). Nevertheless, the impact on poor nations resulted in a low degree of accomplishment, which had an impact on the usage of sustainable construction practices. The obstacles pertaining to sustainability in the building industry have an impact on this practice's adoption(Toriola-Coker et al., 2021). These barriers are vital to the adoption of sustainable construction practices within the construction industry in Nigeria.
In earlier research on sustainable building practices in Nigeria, the capacities of construction companies were examined (Dania et al., 2014); sustainable health and safety practices in construction were examined (Okoye and Okolie, 2013); and obstacles to sustainable construction were identified (Daniel et al., 2018). Similarly, some authors have identified a number of obstacles as crucial to the full implementation of sustainable construction practices in Nigeria, including a lack of legislation and government support, inadequate perception and awareness, and poor knowledge.For instance, a research by Osuizugbo et al. (2020) identified ineffective government assistance as well as unnecessary rules and regulations as some of the obstacles to sustainable building. Nevertheless, despite the numerous obstacles highlighted in previous research, a lot of studies have fallen short in identifying the methods for fostering Sustainable Construction Practices within the same investigation. Furthermore, a number of tactics were investigated without the most effective ones being confirmed.As a result, this study has adopted a comprehensive strategy by highlighting the main obstacles to sustainable building methods and outlining the necessary steps to encourage the use of these methods in Nigeria's construction sector. It is based on this background that the present study seeks to examine the effect of climate on sustainability construction delivery.
Climate change poses significant challenges and risks to the construction industry, as it affects the availability and quality of resources, the performance and durability of materials, the design and planning of projects, and the health and safety of workers. The construction industry is also a major contributor to greenhouse gas emissions, accounting for 39% of global carbon dioxide emissions (Chen et al. 2023). Therefore, there is a need for the construction industry to adopt sustainable practices and technologies that can reduce its environmental impact, enhance its resilience, and improve its efficiency. The goal of this research is to investigate the effect of climate on sustainable construction delivery and propose solutions that can help the construction industry achieve the Sustainable Development Goals (SDGs) set by the United Nations. This research is important because it will provide insights and recommendations for the construction industry to address the challenges and opportunities of climate change, and to deliver projects that are beneficial for the environment, the society, and the economy.
The main objective of this study is to examined the effect of climate on sustainable construction delivery;
The following questions will guide this study;
The following will be hypothesized;
Hypothesis One
H0: There is no significant effect of climate on sustainable construction delivery in Nigeria
H1:There is a significant effect of climate on sustainable construction delivery in Nigeria
Hypothesis two
H0: There is no significant relationship between climate andsustainable construction delivery in Nigeria
H1:There is a significant relationship between climate and sustainable construction delivery in Nigeria.
The findings of this study will help the construction industry to reduce its environmental impact, enhance its resilience, and improve its efficiency by adopting sustainable practices and technologies that can cope with the challenges and opportunities of climate change.
The findings of this study will contribute to the achievement of the Sustainable Development Goals (SDGs) set by the United Nations, especially the goals related to clean energy, sustainable cities, climate action, and responsible consumption and production.
The findings of this study will provide insights and recommendations for the construction industry to address the issues of resource efficiency, carbon emissions, policies, models, life cycle assessment, and sustainable materials in the context of climate change.
The findings of this study will support the health and well-being of the building occupants and users by creating comfortable, safe, and durable spaces that are responsive to the local climate and culture.
The findings of this study will foster innovation and creativity in the design and construction of buildings, as well as the development and application of new materials and technologies that can mitigate or adapt to the effects of climate change.
It can enhance the competitiveness and profitability of the construction industry by reducing the costs and risks associated with climate change, as well as creating new market opportunities and value propositions for green construction.
This study will be limited to the effect of climate on sustainable construction delivery. Specific location for this study will be in Lagos State, Nigeria and the participants will constitutebuilding contractor, and engineers who reside in the area of the study.
