There are some environmentally critical areas (ECAs) in cities such as flood flow areas, agricultural land, canals, rivers, water bodies, forests and hills that need to be conserved from land transformation. The purpose of this paper is to review the compliance, challenges and significance of urban planning, and to develop a contextual framework of urban planning for environmental area conservation to improve the urban environment in case study city Dhaka, the capital of Bangladesh.

This research is based on a qualitative thematic analysis of the available relevant literature.

This research identified non-compliance of the contemporary urban plans such as indiscriminate land conversion activities in the ECAs. Conflicting interests between the urban plans concerning protection of the conservation areas and business interests of the community people and the real estate development companies are identified as the major challenges. Dhaka faces several environmental problems such as loss of biodiversity and ecosystem, waterlogging, flooding, pollution, reduction of vegetation, groundwater depletion, temperature increase and a reduction in agriculture and fishing because of land conversion in the ECAs.

Urban planning with effective conservation area management, conflict resolution through communication and participation, creation of economic opportunity to generate income from the ECAs and assessment of the conservation strategies and interventions might ensure environmental conservation in Dhaka.

The conceptual framework of urban planning for environmental conservation is innovative as this could be a basis for other cities in Bangladesh and in other developing countries.
