This book aims to explore a science-based path to climate actions through planning and design interventions. It reports the latest outcomes (e.g., results, cases, schemes, and tools) by presenting a comprehensive framework for addressing climate change in (i) climate risk sssessment and analytical frameworks, (ii) nature-based and ecosystem-oriented planning approaches, (iii) design and technological innovations for climate adaptation, and (iv) governance, operational frameworks, and implementation pathways. The framework respects diverse application features and feasibility in a variety of geographical, social, economic, cultural, and morphological contexts.
