Abstract
Geomorphic processes operate at multiple spatio‐temporal scales and different levels of hierarchy. It is therefore necessary to understand the linkages of landscapes across various scales and levels to gain insights into their interactions and feedbacks. Connectivity is an emergent property of the hydro‐geomorphic systems, and it is gradually evolving into a unifying concept in geomorphology. The connectivity approach has the potential to be applied extensively to diverse hydro‐geomorphic systems of India to understand their complexity as well as for designing effective management practices for river systems and wetlands, optimizing water resources for agriculture, and monitoring and restoration of habitats. Studies on connectivity, particularly in geomorphic context, have been growing steadily in India, albeit at a much slower pace compared to the global trends. This article undertakes a brief overview of the global developments particularly in terms of providing some clarity among the different types of geomorphic connectivity and their inter‐relationships and feedbacks. We then take stock of the connectivity research in India in recent years as applied in different hydrogeomorphic systems across the country. We utilize a number of Indian case studies to illustrate the important developments and applications of connectivity concepts, and also present future perspective of this important field with special relevance to India. © 2020 John Wiley & Sons, Ltd.
