The establishment and alteration of any coastal feature is largely dependent upon complex hydrological and geomorphologic processes. Therefore, understanding hazard factors and threat risk level is crucial for mitigating risk in coastal zones. This study examines coastal vulnerability factors and their influence along the Coastal Andhra Pradesh (CAP) region in India. CAP has been exposed to frequent hydrological and meteorological hazards due to variations in the geographical, geological, and bathymetric characteristics. Despite substantial vulnerabilities, the risk to the coastline of Andhra Pradesh has not been rigorously evaluated. The current research systematically reviews the drivers and effects of hazards and vulnerabilities in CAP. Findings indicate that urban cities have a considerably higher risk of cyclones and floods due to their locations on the Bay of Bengal tectonic plate, the topology of this coastal region, and higher population density. The study revealed that the Coastal Vulnerability Index (CVI) data along CAP is mostly gathered using low-resolution satellite data and/or field observation surveys. The study further revealed that there are very few existing mitigation strategies developed or discussed within the obtained results. However, more accurate data gathering techniques for coastal vulnerability factors are available such as Unmanned Aerial Vehicles (UAVs): Air-borne and LiDAR sensors, which provide very high resolution data and low-cost accessibility to physically inaccessible places, making them suitable for vulnerability data collection in coastal locations. These findings are useful for stakeholders seeking to reduce or ameliorate the impact of coastal disasters and their impacts on the CAP economy, environment, and population. The study further helps to reduce the existing shortcomings in the assessment techniques used previously.

Many international organizations embrace the ideals of resilience and inclusion in the service of marginalized communities but neglect their inclusion in post-disaster settings. It is imperative to explore the challenges faced by marginalized communities to increase their inclusion in the post-disaster context. Therefore, this paper presents a systematic literature review of the challenges facing marginalized communities in the post-disaster context. The study identified 57 challenges faced by children, women, people with disabilities, and older adults under six categories: social, health, political, infrastructure, economic, and communication. The most common challenges all four marginalized communities face are the development of post-traumatic stress disorder, the struggle to acquire the necessities of life due to unequal distribution, the lack of income-generating opportunities, and sexual and gender-based violence. Most studies focus on women’s challenges, followed by those of children, older adults, and persons with disabilities. The study also explored the challenges faced in terms of intersectionality, experienced by groups of people who fall under more than one marginalized community. Finally, a conceptual framework was developed to improve the inclusion of marginalized communities during the post-disaster context by incorporating the challenges as one of the key components of the framework.

Purpose: Building information modelling (BIM) claims to be spearheading the modern technological revolution in the global construction industry. While scholars have emphasised the cruciality of BIM, associated costs have been identified as one of the major barriers to successful BIM implementation, as is the case in Sri Lanka. Besides, lean principles (LPs) are known for increasing efficiency, quality and eliminating waste, thereby reducing overall costs. Hence, this research aims at addressing the BIM implementation barrier associated with costs by applying suitable LP, enhancing overall value by minimising value-insignificant activities.Design/methodology/approach: The study adopted a qualitative research approach. 10 experts with expertise in both BIM and LP were targeted for the primary data collection through semi-structured interviews. The collected data were analysed using manual content analysis.Findings: Research findings discovered the cost centres that can be applied to the LPs and the effective LPs that can be applied with the cost centres of BIM implementation. The theoretical implication of the study is to provide insights into a potential application of LP for BIM cost centres, whereas practical consequences include the identification of LP's potential to minimise BIM cost centres, ergo, achieving a successful BIM implementation.Originality/value: This study will be the first of its kind in the Sri Lankan construction industry, intending to apply LP with BIM implementation cost centres to achieve a successful implementation. This research also has paved the way forward for further research on the application of both the BIM and LP concepts for similar construction industries in developing countries across the world and in addressing other BIM implementation barriers.

This study aimed to examine post-flood management, with a particular focus on enhancing the inclusivity of marginalised communities through stakeholder analysis. This study was based on an interpretivist mixed method approach, under which 30 semi-structured stakeholder interviews were conducted. Interest versus power versus actual engagement matrix, social network analysis, and thematic analysis techniques were employed under the stakeholder analysis tool to analyse the collected data. The findings highlight the lack of clearly defined responsibilities among key stakeholders. Marginalised communities and community-based organisations have a high level of interests but a low level of power in decision making, resulting in weak engagement and the exclusion of their perceptions. This lack of collaboration and coordination among stakeholders has made marginalised communities more vulnerable in post-flood situations, as their interests are not defended. The findings emphasise the importance of conducting stakeholder analysis in the decision-making process to enhance stakeholder engagement and interaction, as well as promote inclusivity of marginalised communities in the post-flood recovery efforts of the government. Finally, this study recommends developing strategies to improve collaboration among stakeholders, fostering inclusiveness and customising these strategies according to the different types of stakeholders identified through stakeholder analysis.

All over the world, environmental pollution has become a major environmental issue at present. As the construction industry extracts a high amount of natural resources compared to any other industry, it can be known as one of the significant causes of environmental pollution. In order to protect the environment from harmful human activities, there is a massive demand towards sustainable construction practices. Circular Economy (CE) concept has been identified as a way forward to sustainable construction practices. It has been identified that implementing CE in the construction industry has many barriers, enablers and drivers. Hence, this study aims to qualitatively analyse the relevance of the barriers identified through a literature survey in the global context towards circular economy implementation of the Sri Lankan context. Semi-structured interviews were carried out among industry experts and academics who have experience and knowledge of the CE concept. The findings of this study indicate that the practical implementation of CE in Sri Lankan built environment has many barriers as it is still in an early stage. This study concludes that the construction industry stakeholders should be aware of these concepts, and primarily the authorities should focus more on this concept to move forward with a sustainable construction industry and protect the environment.
