Abstract
A unified land use classification system with mutually exclusive definitions of each land use category helps to avoid inconsistencies in the planning process and, most importantly, ensures effective implementation of development control tools. In Bangladesh, the planning authorities prepare land use plans by independently deciding the land use classes. This study aims to explore the nature of inconsistencies in the land use classification systems followed by different planning institutions in Bangladesh and understand their corresponding consequences. To conduct the study, land use plans prepared by different planning institutions have been collected. Based on descriptive analysis, the study shows that the types of land use classes in land use plans change over time, between administrative units, and in different parts of the country. Even authorities are not consistent in maintaining a classification system in their subsequent plans. Moreover, the plans retain ambiguous definitions of land use classes. The classification and definitions of the land use classes are not well linked with different national acts, rules, and policies relating to environmental and natural conservation, which makes it difficult to control development and protect natural, environmental, and cultural resources. This study has the potential to help us understand the importance of a unified land use classification system. Utilizing concept hierarchy, the study has also developed a system for land use classification in Bangladesh that will assist in future research, planning, and policymaking.
