Climate change is a widespread and ongoing issue that is threatening our existence more and more every day and is reflected in matters such as global warming and food and water scarcity. Human activities have become the main factor at play when it comes to the rapid deterioration of our environment, mainly due to the burning of fossil fuels which consequently produces heat-trapping gases when burned.

Besides threatening life on earth for humans and all of biodiversity, these environmental changes affect human health, causing physical and even psychological conditions such as asthma, renal failure, pre-term birth and anxiety-related response or disorders. There are ongoing efforts to decrease the rate of our climate’s deterioration such as attempting to use renewable energy rather than fossil fuels and opting for more green alternatives in general and not just in regards to fuels.

In an effort to keep to conversation going, IEREK is planning its 3^rd international conference on "Health & Environmental Resilience and Livability in Cities (HERL)", which is a chance for scientists and researchers from around to globe to come together and excavate solutions for the ongoing and recent environmental threats. IEREK welcomes participants of various backgrounds and offers them the opportunity to publish in Scopus-indexed ASTI book series by Springer. The proceedings of the 3rd International Conference on Health & Environmental Resilience and Livability in Cities (HERL), will be hosted online in collaboration with the esteemed Perugia University, Italy. In recent decades, the world has witnessed an unprecedented pace of urbanization, with a significant majority of the global population now residing in urban areas. As cities continue to expand and evolve, the interplay between health, environmental sustainability, and urban livability has become an increasingly pressing concern.

The theme of this conference underscores the critical importance of fostering resilient, sustainable, and livable urban environments for the well-being of current and future generations. As cities grapple with multifaceted challenges ranging from public health crises and environmental degradation to social inequities and infrastructure deficiencies, the need to engage in interdisciplinary dialogue and collaborative action has never been more pertinent.

We extend our sincerest gratitude to all contributors, participants, and supporters who have contributed to the success of the 3rd HERL conference. Your collective dedication to advancing the cause of urban health and environmental resilience is truly commendable, and we look forward to the enduring impact of our shared endeavors.

Against this backdrop, the 3rd HERL conference provides a platform for scholars, practitioners, policymakers, and stakeholders from around the globe to convene, exchange insights, and chart a course toward healthier, more resilient, and livable cities. By delving into topics such as urban health disparities, green infrastructure, green energy, material for sustainable and renewable energy, climate resilience, community engagement, and innovative urban planning, this conference aims to catalyze transformative approaches that can enhance the health and well-being of urban residents while safeguarding the natural environment.

Furthermore, the collaboration with Perugia University underscores the international scope of this undertaking and the shared commitment to advancing knowledge and solutions in the realm of urban health and environmental resilience. Through this collective endeavor, we aspire to harness the collective expertise and experiences of diverse participants to generate actionable strategies and best practices that can be applied in urban settings worldwide.
