Purpose: The UK has experienced a number of flood events in recent years, and the intensity and frequency of such events are forecast to further increase in future due to changing climatic conditions. Accordingly, enhancing the resilience of small and medium‐sized enterprises (SMEs) – which form an important segment in a society – to flood risk, has emerged as an important issue. However, SMEs often tend to underestimate the risk of flooding which tends to have a low priority in their business agenda. The purpose of this paper is to undertake an investigation of adaptation to the risk of flooding considering community‐level measures, individual‐level property protection, and business continuity and resilience measures.Design/methodology/approach: A total of four short case studies were conducted among SMEs to identify their response to flood risk, and what measures have been undertaken to manage the risk of flooding.Findings: It was observed that SMEs have implemented different property‐level protection measures and generic business continuity/risk management measures, based on their requirements, to achieve a desired level of protection.Practical implications: SMEs are likely to positively respond to property‐level adaptation following a post‐flood situation. It is important that information such as costs/benefits of such measures and different options available are made accessible to SMEs affected by a flood event.Social implications: Implementation of property‐level adaptation measures will contribute towards the long term adaptation of the existing building stock to changing climatic conditions.Originality/value: The paper contributes towards policy making on flood risk adaptation and SME decision making, and informs policy makers and practitioners.

Wider scientific community now accept that the threat of climate change as real and thus acknowledge the importance of implementing adaptation measures in a global context. In the UK, the physical effects of climate change are likely to be directly felt in the form of extreme weather events, which are predicted to escalate in number and severity in future under the changing climatic conditions. Construction industry; which consists of supply chains running across various other industries, economies and regions, will also be affected due to these events. Thus, it is important that the construction organisations are well prepared to withstand the effects of extreme weather events not only directly affecting their organizations but also affecting their supply chains which in turn might affect the organisation concerned. Given the fact that more than 99% of construction sector businesses are SMEs, the area can benefit significantly from policy making to improve SME resilience and coping capacity. This paper presents the literature review and synthesis of a doctoral research study undertaken to address the issue of extreme weather resilience of construction sector SMEs and their supply chains. The main contribution of the paper to both academia and practitioners is a synthesis model that conceptualises the factors that enhances resilience of SMEs and their supply chains against extreme weather events. This synthesis model forms the basis of a decision making framework that will enable SMEs to both reduce their vulnerability and enhance their coping capacity against extreme weather. The value of this paper is further extended by the overall research design that is set forth as the way forward. Santruka Gana daug mokslininku jau sutinka, kad klimato kaitos gresme yra reali, taigi pripažista, kaip pasauliniame kontekste svarbu diegti prisitaikymo priemones. Tiketina, kad Jungtineje Karalysteje fizinis klimato kaitos poveikis bus tiesiogiai jaučiamas per ekstremalius meteorologinius reiškinius. Prognozuojama, kad kintant klimato salygoms ju skaičius ir intensyvumas ateityje dides. Tokie reiškiniai paveiks ir statybu pramone, kuria sudaro per kitas ivairiausias pramones šakas, ūkius ir regionus einančios tiekimo grandines. Taigi svarbu, kad statybu organizacijos būtu tinkamai pasiruošusios atlaikyti ekstremalius meteorologinius reiškinius, kurie daro tiesiogine itaka ne tik šioms organizacijoms, bet ir ju tiekimo grandinems, kurios savo ruožtu gali paveikti atitinkama organizacija. Daugiau kaip 99 proc. statybu sektoriuje veikiančiu imoniu priklauso SVV kategorijai, tad šiai sričiai išties praverstu politika, gerinanti SVV atsparuma ir gebejima susitvarkyti. Šiame darbe pateikiama literatūros apžvalga ir trumpai pristatomas daktaro disertacijos tyrimas, kuriuo siekta išnagrineti statybu sektoriaus SVV ir ju tiekimo grandiniu atsparuma ekstremaliems meteorologiniams reiškiniams. Pagrindinis darbo indelis, pravartus ir mokslininkams, ir praktikams, tai sintezes modelis, kuriame suformuluojami veiksniai, didinantys SVV ir ju tiekimo grandiniu atsparuma ekstremaliems meteorologiniams reiškiniams. Šis sintezes modelis yra sprendimu priemimo sistemos pagrindas, o sistema SVV leis ne tik mažinti pažeidžiamuma, bet ir didinti gebejima susitvarkyti esant ekstremaliems meteorologiniams reiškiniams. Šio darbo verte dar labiau padidina bendras tyrimo modelis, pateikiamas kaip žingsnis pirmyn.

This study evaluated the build-back-better considerations in post-disaster recovery, following the devastation of Chipinge and Chimanimani communities by Cyclone Idai-induced floods in 2019. Conducted in 2020, the study assessed the impact of Cyclone Idai-induced floods on communities in Chipinge and Chimanimani Districts of Zimbabwe; evaluated the build-back-better considerations; and analyzed the lessons learned. Based on a qualitative approach and case study design, the study depended on focus group discussions, interviews, and researcher observations to gather data from 85 participants. The findings indicate that Cyclone Idai-induced floods seriously impacted human lives, infrastructure, and livelihoods of communities that had been living with flood risk and vulnerability. Build-back-better considerations were absent in much of the post-disaster recovery effort to address the cyclone disaster impact. There are important early lessons for both practitioners and community members to learn from the Cyclone Idai event. These lessons still can inform policy and disaster risk reduction practice in the medium and long term. Build-back-better should be a mandatory objective in the recovery from any disaster impact. Continuous training is also recommended to improve the disaster knowledge of stakeholders and increase local ability to cope with future disaster events.

The construction industry is susceptible to extreme weather events (EWEs) due to most of its activities being conducted by manual workers outdoors. Although research has been conducted on the effects of EWEs, such as flooding and snowfall, limited research has been conducted on the effects of heatwaves and hot weather conditions. Heatwaves present a somewhat different risk profile to construction, unlike EWEs such as flooding and heavy snowfall that present physical obstacles to work onsite. However, heatwaves have affected the construction industry in the UK, and construction claims have been made due to adverse weather conditions. With heatwaves being expected to occur more frequently in the coming years, the construction industry may suffer unlike any other industry during the summer months. This creates the need to investigate methods that would allow construction activities to progress during hot summer months with minimal effect on construction projects. Hence, the purpose of this paper. Regions such as the Middle East and the UAE in particular flourish with mega projects, although temperatures soar to above 40̊C in the summer months. Lessons could be learnt from such countries and adapted in the UK. Interviews have been conducted with a lead representative of a client, a consultant and a contractor, all of which currently operate on UAE projects. The key findings include one of the preliminary steps taken by international construction companies operating in the UAE. This involves restructuring their entire regional team by employing management staff from countries such as Lebanon, Palestine, Iraq, and their labour force from the sub-continent such as India and Pakistan. This is not only due to the cheap wage rate but also to the ability to cope and work in such extreme hot weather conditions. The experience of individuals working in the region allows for future planning, where the difference in labour productivity during the extreme hot weather conditions is known, allowing precautionary measures to be put in place
