Step 1: Alternate structuring: a simple 'before vs. now' comparison:
Historically, land use change in India was mainly about EXPANDING cultivation into forest/wasteland to feed a growing population; today, the change is increasingly about CONVERTING farmland itself into urban, industrial, and infrastructural use.
Step 2: Draw the implication:
This shift — from land clearing for farming to farmland being consumed by cities — is what defines the 'changing' pattern referred to in the question, alongside continued degradation of the remaining agricultural land.
Step 3: Final Answer:
The historical trend of extending cultivation into new land has given way to a newer trend of agricultural and forest land being lost to urban and industrial expansion, alongside ongoing land degradation.
