Crop Diversification in India (1990–2016): Implications for the Eastern and Northeastern States

Abstract

This study utilises data from the Agriculture Census for 1990–1991, 2005–2006 and 2015–2016, employing the Herfindahl-Hirschman Index (HHI) to assess crop diversification in Indian states. The overall HHI declined from 1990–1991 to 2015–2016, indicating increased crop diversification nationally. However, the proportion of states exceeding the overall average HHI significantly decreased, indicating a shift towards specialisation or monoculture in some states. The analysis notes a decrease in the gross cropped area (GCA) under total food crops (TFC) and an increase in total non-food crops (TNFC). Despite the overall decline in TFC, high-value crops like horticultural produce, sugar crops, spices, and condiments have seen improvement. Focusing on the Eastern region (ER) and the Northeastern region (NER), the study reveals diversification in NER due to higher allocation of land to high-value crops, while economically disadvantaged states in the ER, such as Bihar and Odisha, show a trend towards crop specialisation, potentially affecting overall food security in the region. The study emphasises the need for government support to address persistent vulnerabilities in poverty, unemployment, and low yields in cereals, pulses, and oilseeds in these regions, recommending inputs, infrastructure development, insurance, and market linkages for perishable items to enhance food security.
