This book presents the proceedings of the 2024 Research Day on Human Settlements Planning. The book contains abstracts of the oral and poster presentations of the research outputs of students taking up Bachelor of Science in Human Ecology at the College of Human Ecology, University of the Philippines Los Ba˜nos, Laguna, Philippines. The outputs are from their Undergraduate thesis (CERP 200), Research Methods in Human Ecology (HUME195), and Seminar in Human Ecology (HUME 199) courses. The contributions in this proceedings emphasize the interrelationships between human societies and their ecosystems. Drawing on interdisciplinary perspectives, the research papers presented explore how human settlements, whether urban or rural, can be designed and managed to enhance the well-being and quality of life for all its inhabitants. The discussions range from studies on human and family development including individual and family dynamics, social organizations and policies, and climate change and disaster risk reduction. By engaging with both theoretical frameworks and practical applications, the students’ research offers valuable insights into how human ecological principles, theories, and frameworks can be applied to the development, planning, and management of sustainable and resilient communities. This collection of abstracts provides a platform for young scholars to contribute to the ongoing discourse on human settlements planning, with the aim of advancing solutions that meet both the present and future challenges in environment and development.
