B) Regional and Areal analysis

During the later colonial period, there was a shift in the approach to understanding and studying different regions and areas. This shift can be categorized as regional and areal analysis.

Regional analysis refers to the study of specific regions or areas with a focus on their unique characteristics, including their physical geography, climate, resources, and cultural aspects. It involves examining the similarities and differences between different regions and understanding how these factors shape the development and dynamics of each region.

Areal analysis, on the other hand, looks at the spatial patterns and distribution of various phenomena within a specific area or region. It involves mapping and analyzing the distribution of different variables such as population, economic activities, land use, and cultural practices. Areal analysis helps in identifying patterns and understanding the spatial organization of different aspects within a given area.

By adopting a regional and areal analysis approach, scholars and researchers aimed to gain a deeper understanding of the complexities and diversities present within different regions. This approach allowed for a more nuanced and comprehensive understanding of the colonial territories and their unique characteristics.

The later colonial period was marked by increased exploration and description of different regions. Scholars and explorers ventured into new territories, documenting their findings and observations. This exploration and description of new lands contributed to the growing body of knowledge about different regions and laid the foundation for regional and areal analysis.

Overall, the regional and areal analysis approach during the later colonial period focused on understanding the unique characteristics and spatial patterns of different regions. It allowed for a more comprehensive understanding of the colonial territories and their diverse landscapes, cultures, and socio-economic dynamics.
