Participatory Development by Arif Hasan emphasizes the importance of involving local communities in the planning and decision-making processes of urban development. The work advocates for a bottom-up approach, where communities actively engage in shaping their own development, ensuring that projects reflect their needs and priorities. Hasan argues that participatory development leads to more sustainable, inclusive, and contextually relevant outcomes, while also fostering social cohesion and empowerment. The book highlights case studies and practical strategies for implementing participatory practices in urban planning and development.
