Integrated approach to risk management of future climate change impacts

Pages 1-10 | Published online: 08 Feb 2011
 

Abstract

The vulnerability of the built environment will be influenced by global-scale climate change. However, there are large uncertainties associated with the future performance of buildings due to changes in regional- and local-scale climatic impact. The use of modern risk-management theories is discussed for developing cross-disciplinary strategies to meet the challenges of future climate change. It is shown that there are benefits to be gained from the introduction of risk-management strategies within a greater extent of the construction industry. Cross-disciplinary risk-based management strategies (ensuring cooperation along vertical decision-making lines), together with design guidelines that account for both historical local climatic conditions and scenarios for future changes, can be an important step towards a more active and dynamic way of ensuring a high-quality construction process and a sustainable built environment. Reducing the potential for defects or damage through the development of technical and organizational preventive measures (a risk-based management strategy) while at the same time applying the precautionary principle and discursive strategies in the design, construction and geographical localization of buildings, is likely to increase the robustness of the built environment in the light of the unknown risks of future climate change.

La vulnérabilité du milieu bâti va subir l'influence des changements climatiques à l'échelle du globe. Il reste toutefois de grandes zones d'incertitude associées aux futures performances des bâtiments du fait de l'impact variable des changements climatiques à l'échelle régionale et locale. L'auteur examine le recours aux théories modernes de gestion des risques afin de formuler des stratégies interdisciplinaires capables de relever les défis que posent les futurs changements climatiques. Il apparaît qu'une grande partie de l'industrie du bâtiment pourrait bénéficier de l'introduction de stratégies de gestion des risques. Ces stratégies interdisciplinaires (qui favorisent la coopération le long de processus décisionnels verticaux) ainsi que les lignes directrices qui tiennent compte à la fois des conditions climatiques locales historiques et de scénarios qui intègrent les changements à venir, peuvent constituer une étape importante vers une manière plus active et plus dynamique d'assurer un processus de construction de haute qualité et un milieu bâti durable. La réduction des risques de défauts ou d'endommagement par la mise en œuvre de mesures préventives sur les plans technique et organisationnel (une stratégie de gestion basée sur les risques), l'application du principe de précaution et des stratégies discursives sur la conception, la construction et la localisation géographique des bâtiments vont vraisemblablement améliorer la robustesse du milieu bâti à la lumière des risques inconnus posés par les futurs changements climatiques.
