v1.c24.s6.2

Scholars have made several, sometimes conflicting, assessment about the nature and volume of rainfall in the Harappan period, hence we cannot determine precisely the extent to which agricultural prosperity of the Harappans was due to this source of irrigation. In the absence of any definitive evidence about artificial irrigation the fact of the predominance of winter crops in the Harappan economy has been taken to be based on ‘flood irrigation farming’ using moisture and silt provided by river floods.
