The pollen analytical investigations of a 3·30 m deep profile from a horse-shoe lake in the Ganga Valley have been carried out. The lake is situated closeby to an archaeological site Sarai-Nahar-Rai in Pratapgarh District. The pollen frequencies were calculated in terms of total land plants and a pollen diagram has been constructed.
In the last 8000 years, there have been four phases of vegetational developments reflecting directly on four brief phases of climate such as Very Arid, Arid, Semi-Arid and Semi-Humid. The abundance of grasses throughout the pollen diagram has revealed the existence of an open savannah forest. The arboreal vegetation is poor and represented by a few scattered trees and shrubs.
The commencement of arable and pastoral economy chiefly based on cereal pollen has been recognized during ca. 4500 b.p. which prospered in the succeeding phases.
