Hey, nice compilation! It really helped. I would like to recommend a written version on Concentric Zone Model with valuable facts and information. Details on other such topics also available!
The Lewis model, presented in , dominated development theory between the s and s. It is also known as the two sector model , and the surplus labour model. It focused on the need for countries to transform their structures, away from agriculture, with low productivity of labour , towards industrial activity, with a high productivity of labour. Though highly influential at the time , and despite the considerable logic of the Lewis approach , the benefits of industrialisation may be limited because:. A s early as , Allen Fisher had suggested that economic progress would lead to the emergence of a large service sector, which followed the development of a primary and secondary sector. Later, in , Colin Clark developed this theme to create the Clark-Fisher development theory, also called the Fisher-Clark model.
Sector Model also known as Hoyt Model and Hoyt Sector Model is an urban land use model which talks about spatial arrangement of activities in an urban area. Big cities and towns have always been an area of research and have caught the attention of scholars and academicians. Homer Hoyt gave sector model which is also known as Hoyt Model, in which explains how cities grew and activities arranged themselves in the form of concentric zone.
With passing time urban areas have become increasingly complicated. Each urban area has a variety of functions. The manner in which the humans use the land changes throughout the urban area due to the different activities that take place. With time, a number of models have been created based on studies to identify patterns of land use to overcome the complexity of land uses found throughout a city. Land use models are theories which attempt to explain the layout of urban areas.
