Abstract

This study assessed the impact of tilapia farming on poverty in the States of Oaxaca, Guerrero, and Chiapas, which have the highest levels of poverty in Mexico. The study uses both 2018 data from a sample of micro- and small-sized farmers in these States, and the Mexican government’s multidimensional poverty methodology. Results show fewer tilapia farmers in extreme or moderate poverty compared to the general population’s value in the municipalities and States where these farms are located, therefore asserting the positive impact of the activity. While cage farmers have more social rights deprivations, their income is greater compared to that of tank and pond farmers. Tilapia projects are also relevant to food security, increasing both household fish and animal-protein consumption.

摘要

本研究评估了罗非鱼养殖对墨西哥贫困程度最高的瓦哈卡州、格雷罗州和恰帕斯州贫困的影响。该研究使用了来自这些州的微型和小型农民样本的 2018 年数据，以及墨西哥政府的多维贫困方法。结果显示，与这些养殖场所在的市和州的一般人口价值相比，处于极端或中等贫困状态的罗非鱼养殖者较少，因此肯定了该活动的积极影响。虽然网箱养殖者的社会权利被剥夺更多，但与水箱和池塘养殖者相比，他们的收入更高。罗非鱼项目也与粮食安全相关，增加了家庭鱼类和动物蛋白的消费。
