"This book offers a comprehensive exploration of sustainable solid waste management practices in delta regions worldwide. With attention to detail, this work presents a systematic review, illuminating case studies, original research, and insightful meta-analyses tailored to address the unique challenges faced by delta environments. Home to over half a billion people, or approximately 7% of the global population, delta regions are dynamic ecological and social landscapes, despite accounting for only 1% of the world's land area. Yet, they play a pivotal role in national economies. Given the significant size and density of populations in these regions, understanding solid waste generation patterns, trends, and impacts is essential for global sustainability efforts. By focusing on deltaic regions, we aim to provide essential insights into effective policy planning and advancements in social and ecological sustainability. Explore a diverse array of topics, including the bioconversion of food waste into environmentally friendly compounds, sustainable production and disposal practices to address water quality concerns, and innovative waste management applications to combat channel clogging and flooding in delta districts. Delve into best practices for managing climate-related flood risks, addressing urban responses, and tackling environmental pollution associated with unmanaged waste disposal in delta catchments. Additionally, gain valuable insights into the regulatory framework guiding waste management practices, particularly in delta regions facing significant plastic pollution challenges. This book navigates the complexities of solid waste management in delta regions, paving the way for a more sustainable future."
