Every nation has some identity attributes that make it distinct from other nations, of which settlement pattern is the most important one. There are studies on essential components of a viable settlement and also there are studies on the evolution pattern of settlements in this region. But, no studies were found that explains the “generic pattern” of any particular settlement typology. It is observed in the Bengal delta that every time a settlement begins to evolve, it follows the same common principles, giving rise to a certain pattern. To identify that pattern of Bengal settlements, the present coastline, which is the active delta and represents the thousands of years old geo-climatic context of this region, has been analysed. The objective of this study is to identify the generic settlement pattern in the Bengal Delta. The sub-objectives are to find out the phenomenon behind the evolution of a particular settlement pattern in the Bengal Delta in response to traditional ecological knowledge (TEK) and finally to validate the settlement pattern as the generic one which can be used as a basis for future planning and design at any scale and level.
The research has been conducted through a triangulation of literature review, phenomenological approach and qualitative data analysis. The analogical context is identified through the historic phenomenological interpretation of available literature. The historic settlement pattern is reconstructed for the phenomenological study in the present context to verify the prevalence frequency and intensity of the historic pattern. This research essentially attempted to connect methodically, the various threads and fill up the gaps to identify the order that prevails in the settlement pattern of the Bengal Delta, thereby testing the hypothesis, that “Bengal Delta has a generic settlement pattern”. From the three stratified zones, 22 case study settlements were selected at random for the field survey, KII and FGD. On analysing all the data, historic interpretation of the settlement patterns and logically identifying the phenomenon behind the development, a ‘generic settlement pattern’ is revealed. Theoretically bracketed settlement components, their growth pattern and character is further scrutinized in the analogous historic Bengal delta context to ‘confirm’ that they are tied up in a single thread and further validated in both rural and urban context.
The generic settlement module is found to vary between (1 km to 1½ km) x (1 km to 1½ km) with a population ranging from 30-100 homesteads. Depending on the context, scale, and level of development, this module takes on various shapes through logical transformation, mutation, adaptations or resiliencies. The elements of a settlement are connected both physically and psychologically. The generic settlement pattern as identified comprises of four parts i.e. homogeneous part, central part, circulatory part and community interaction part. The communication route gives the settlement inter and intra-accessibility with the community facilities and organize the whole settlement spontaneously with TEK and gives shape to the settlement. Settlements in Bengal Delta employ the wisdom, knowledge, and practices handed down from generation to generation. There is an order both in the internal system and external outline of the settlements. The pattern that is identified is generic in nature because it is found to be the basis of all the organic settlements at various scales and levels in Bangladesh (which is a part of the Bengal Delta) unless it is modified by some external forces.
The studies in the Bengal Delta context found some common denominator that provides the basis of a ‘generic pattern’ persisting and prevailing in all levels and scales when evolved by TEK organically. Transplanted ideas not rooted in the context, particularly during the colonial era, has brought about some changes in the settlement pattern that cause chaos. For sustainability purposes ‘transformation’ instead of ‘transplantation’ is identified to be the right approach for settlement planning. The generic settlement pattern that is identified for Bengal Delta can be used as a basic framework for any future settlement planning and design in this region for its sustainability.
