A thematic landscape designed masterplan integrating urban ecology, water planning and social improvements : a vision for the former airport Tejgaon and the district Karail, Dhaka City, Bangladesh

Sammanfattning

The aim of this thesis paper is to integrate three important thematic aspects i.e., improve qualities in the urban ecological situation, provide ideas for handling stormwater flooding and ideas to improve socio-economic aspects for inhabitants. The integration of ideas is illustrated in a masterplan program-sketch in three phases. Dhaka is the capital of Bangladesh. Dhaka is a densely populated fast developing city. The chronological changes of the natural setting due to rapid growth of urbanization in Dhaka city creates an imbalance with nature and disrupts urban ecology. The green and blue structures are replaced with built areas and hard surfaces. The situation for urban ecology in the city of Dhaka affects storm water flooding and social wellbeing. The methods used for background knowledge to this proposal are literature reviews, document searches, interviews, GIS analysis and a study of role models from different countries and contexts where a variety of solutions, proposals and functions inspired me in my own sketching. The methods and the background for this thesis were used to formulate guidelines to support the overall program-sketch for the three phases in a masterplan. The first phase program-sketch includes redesigning the informal settlements in Karail into better living conditions for the dwellers according to Patrick Geddes theories by keeping the overall road- and block structure and provide new shelter, job opportunities and adding recreational values to the area. The second phase concentrated on re-establishing of water streams in a green park according to the philosophy of Fredrick Law Olmsted, and in the third phase the former airport Tejgaon to become a large green area for social meetings, recreation activities for the Dhaka city inhabitants and provide job opportunities for the informal dwellers. The discussion on strengths, limitations, challenges, and further development ends with a conclusion that it is of great importance to work integrated with the three thematic aspects urban ecology, storm water flooding and social wellbeing on an overall level and with understanding of the issues among both specialists, politicians, and inhabitants to be able to implement necessary change towards sustainability.
