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.

气候变化对小岛屿粮食安全的影响：毛里求斯案例

本文以毛里求斯为例，研究气候变化导致的高粮价对小岛屿粮食安全的影响。气候变化可能会对农产品价格产生不利影响。该研究推导出并计算了政府成本以及世界大米价格上涨对毛里求斯消费者的福利影响。本研究使用均衡置换模型发现，如气候变化和大米价格的文献预测的那样，大米价格上涨 35% 将导致政府支出增加 28.8%，即额外支出支持粮食安全补贴计划。以 2012 年为基准，
