Assertion: Land use under the head " non-agricultural uses" has registered the highest growth in India since its Independence.
Reasoning: The area under non-agricultural uses is increasing at the expense of wastelands and agricultural land.

Both Assertion (A) and reasoning (R) are correct and but R is not the correct explanation of A.

India has undergone major changes within the economy over the past four or five decades, and this has influenced the land-use changes in the country. These changes between 1950–51 and 2014–15 have been shown below. Four categories have undergone increases, while four have registered declines. Share of area under forest, area under non-agricultural uses, current fallow lands and net area sown have shown an increase. The rate of increase is the highest in case of area under non-agricultural uses. This is due to the changing structure of Indian economy, which is increasingly depending on the contribution from industrial and services sectors and expansion of related infrastructural facilities. Also, an expansion of area under both urban and rural settlements has added to the increase. Thus, the area under non-agricultural uses is increasing at the expense of wastelands and agricultural land.
