Understanding the Sustainability and Growth Dynamics of Shrimp Aquaculture in Odisha, India: A Decomposition Approach

Abstract

In this paper, we examine the growth and decomposition trends of the area, production, and yield of the shrimp aquaculture sector in Odisha. We use annual time series data for the period 2010–11 to 2022–23, and with the help of exponential function, we evaluate growth rate and trend. CV and CDVI were used to analyze production instability. Minha’s decomposition model was used to evaluate the contributions of area and yield to change in farm production. Our findings show a commendably high compound growth rate of 11.55 per cent for area, 26.12 per cent for production, and 13.06 per cent for yield. The instability index, CV and CDVI of the area are low. The influence of the area, yield, and interaction effects accounted for 26.35 per cent, 22.18 per cent, and 51.47 per cent, respectively, of shrimp production. The analysis of decomposition and area effect stresses the need to understand shrimp production dynamics in Odisha. Monitoring land use patterns and markets and promoting research and innovation is not only securing sustainability, nutritional security, and employment but also the economic development of the state.
