In the wake of increasing natural disasters, a recent study published in the journal ‘Sustainable Structures’ (translated from English as ‘Sustainable Structures’) is shedding light on the potential of earthen dwellings to bolster disaster resilience and contribute to sustainable development goals. Led by Harisankar R. from the Amrita School for Sustainable Futures at Amrita Vishwa Vidyapeetham in India, the research delves into the often-overlooked benefits of vernacular construction techniques, particularly those utilizing earthen materials.
The study examines the dual nature of earthen structures, highlighting both their vulnerabilities and strengths in the face of various hazards. “While earthen buildings can be susceptible to certain disasters, their inherent properties also offer unique opportunities for disaster resilience,” Harisankar explains. By analyzing case studies from around the world, the research demonstrates how modifications and adaptations can transform traditional earthen construction into a robust, disaster-resistant design.
One of the most compelling aspects of this study is its exploration of the intersection between earthen construction and the United Nations Sustainable Development Goals (UN-SDGs). Through a scoring matrix, Harisankar and his team illustrate how earthen materials and methods can significantly contribute to achieving relevant targets of SDGs 01 (No Poverty), 07 (Affordable and Clean Energy), 09 (Industry, Innovation, and Infrastructure), 11 (Sustainable Cities and Communities), 12 (Responsible Consumption and Production), and 13 (Climate Action).
The implications for the construction and energy sectors are substantial. As the world grapples with the need for sustainable, resilient infrastructure, earthen dwellings offer a viable, locally sourced solution that can reduce dependency on conventional building materials and energy-intensive processes. “This study underscores the importance of integrating indigenous knowledge and locally available resources into modern construction practices,” Harisankar notes. “By doing so, we can create buildings that are not only environmentally friendly but also better equipped to withstand the impacts of natural disasters.”
The research also presents a conceptual framework for disaster-resilient recovery planning, emphasizing the need for a community-centric approach that prioritizes vernacular housing techniques. This framework could inform and inspire policymakers, practitioners, and developers to formulate strategies that are both sustainable and resilient.
As the construction industry continues to evolve, the findings of this study could shape future developments in sustainable building practices. By embracing earthen construction techniques, the industry can move towards a more resilient and sustainable future, ultimately contributing to the achievement of the UN-SDGs. The study published in ‘Sustainable Structures’ serves as a timely reminder of the value of traditional knowledge and the potential for innovation within the construction sector.
