Abstract

This paper studies the implications of high food prices resulting from climate change on food security in small islands, using Mauritius as a case‐study. Climate change may adversely impact prices of agricultural commodities. The study derives and calculates the government costs and the welfare effects of an increase in the world price of rice on consumers in Mauritius. Using an equilibrium displacement model, this study finds that an increase in the price of rice by 35%, as predicted by the literature on climate change and rice prices, will result in an increase of 28.8% in government spending, representing the additional outlays to support the subsidy scheme for food security. Using 2012 as the baseline, the welfare analysis results suggest that consumer surplus for ration rice consumers increases by 626 million Mauritian Rupees (MUR) or US$18 million while consumer surplus decreases by MUR454 million (US$13 million) for basmati rice consumers.
