Environmental challenges in the contemporary world are posing significant vulnerabilities to society. Disasters are not simply “natural” phenomena; they are truly socially manufactured events in which preexisting social, economic, and political injustice cause vulnerable communities to lose their homes and means of livelihood at disproportionate levels. Ecological crises are one of the worst threats in the modern-day world, from pollution to the climate crisis. This introductory chapter explores the critical nexus of social work and environment in the context of Disaster Risk Reduction (DRR), emphasizing the interrelationship between social justice, environmental justice, and community resilience. This study investigates the key themes and concepts related to the physical and social environment, social work and environment, DRR and social work practice, contributions of Lena Dominelli and Margaret Alston, and the nexus of social and environmental justice and finally introduces a praxis-based eco-social resilience model. In order to effectively address the social and ecological vulnerabilities exacerbated by ongoing environmental concerns, social work and environmental justice must be integrated.
