Landscape Architecture for Coastal Informal Settlements is a practical, systems-based guide to improving health, hygiene, and everyday living conditions in coastal slums, shanty towns, and informal waterfront communities. Across the world, millions of people live in low-lying coastal settlements where flooding, tidal backflow, pollution, weak sanitation, and overcrowding combine to create chronic health risks. Conventional infrastructure often arrives too late—or not at all. This book shows how landscape architecture can intervene earlier and more effectively by working with land, water, vegetation, circulation, and public space to deliver measurable improvements. Written for practitioners and students, the book bridges landscape architecture with hydrology, engineering, public health, ecology, policy, and community governance . It moves from diagnosis to action: how to read informal settlements as living landscapes of flows and practices; how to design hygiene-first drainage and sanitation environments; how to build cooler, safer public space networks; how to stabilize vulnerable waterfront edges without displacement; and how to ensure projects last through maintenance systems and local stewardship. Inside you’ll find: Clear principles for hygiene-first landscape intervention - Tools for mapping flood risk, drainage failures, and hygiene exposure - Strategies for drainage networks, decentralized sanitation, gardens, shade, and blue-green infrastructure - Prototype models such as the Drainage Spine , Community Hygiene Court , Safe Alley Retrofit , and Tidal Edge Park - Guidance on co-design , maintenance, ethics, and scaling from pilots to citywide policy Grounded in global research and field-tested logic, this is not a utopian master plan. It is a realistic pathway for incremental, participatory transformation —helping coastal informal communities become cleaner, safer, greener, and more resilient, one connected system at a time.
