This paper is based on a large resurvey of villages, after a gap of 20 years, in the eastern and western regions of Uttar Pradesh. Some of the findings from the study indicate that significant changes have taken place during these years in the two regions in respect of socio-economic features, role of groundwater irrigation including groundwater markets, productivity of crops and changing face of the rural elite. The most important trend is that the high-caste supremacy in terms of ownership of modern agricultural implements is on the wane, while backward castes are surging ahead in such ownership.
