Green Horizons: Sustainable Urban Development for Malabe

Project idea

The "Green Horizons" project aims to address the rapid, unplanned development in Malabe, Sri Lanka, which has led to significant environmental degradation, including the loss of wetlands, reduced air and water quality, and increased flooding risks. By integrating sustainable practices and eco-friendly infrastructure, this project seeks to enhance the quality of life and well-being of Malabe's residents. The project leverages the natural ecosystem, particularly wetlands, to create a balanced urban environment that supports food security, reduces pollution, and provides recreational and cultural benefits.

Project description

This project focuses on several key areas to create a sustainable and livable urban environment in Malabe: Wetland Restoration: Restoration of 20% of Malabe's land, currently covered by wetlands, to improve food security, flood protection, and air quality. Development of the canal system for transportation and livelihood opportunities​. Sustainable Building and Infrastructure: Incorporation of green covers and use of renewable energy sources like solar power to reduce CO2 emissions and the urban heat island effect. Design of buildings and infrastructure to promote social cohesiveness, economic development, and increased land value​. Mixed-Use Development: Encouragement of water-dependent and water-enhanced recreational, public, residential, and commercial uses that complement the natural ecosystem. Enhancement of public access to natural resources like rivers and wetlands, ensuring harmony with ecological systems​. Community and Economic Benefits: Creation of a city identity that includes cultural and recreational facilities, fostering community pride and asset development. Development of a diverse neighbourhood with various housing types and transportation alternatives, including public transit, walking, and cycling.
