Over the past four decades, India’s cropping pattern has experienced profound structural changes, with crop diversification emerging as a defining feature. These transformations, spanning the period 1980–81 to 2023–24, have been driven by a combination of economic reforms, climatic variability, technological advancements, and policy interventions. A marked shift has occurred from a cereal-centric production system toward a more diversified agricultural base that increasingly includes horticultural crops, pulses, oilseeds, and other commercial crops. The study highlights the role of government initiatives, innovations in agricultural technology, and changing climatic conditions in shaping these dynamics. To investigate the determinants of diversification, explanatory variables such as percentage of irrigated area (PIA), road density (RD), agricultural credit (AC), and fertilizer use per hectare (FUPH) are examined. These infrastructural and technological factors together explain the evolving trajectory of cropping patterns across India.

This study compares the impact of migration on rural employment in Nigeria and India from 2005 to 2023, exploring its impact on the global economy. Using a dynamic panel Generalized Method of Moments (GMM) model with the Arellano-Bond estimator, the analysis covers 34 observations across two countries, sourced from the World Bank, Nigeria’s National Bureau of Statistics, and India’s Periodic Labour Force Survey. Rural employment rate is the dependent variable, with migration rate as the key independent variable, alongside controls for rural population, foreign direct investment (FDI), and agricultural output. Findings indicate that, a 1% increase in migration reduces rural employment by 1.5% (p < 0.05), driven by labor supply declines in Nigeria (1.2% to 1.6%) and India (0.4% to 0.55%). Rural population and agricultural output positively influence employment, while FDI shows a negative effect due to urban bias. Globally, Nigeria’s remittances (6% of GDP) and India’s urban productivity enhance international labor markets and supply chains, contributing to a $2 trillion economy. Policy recommendations include rural job creation through agricultural technology, economic zones in India, remittance-funded entrepreneurship in Nigeria, and FDI targeting rural development.
