墨西哥巨大的人类环境多样性为初步了解贫富之间的巨大差距提供了一个框架。墨西哥的许多地区仍然以农业为主，在过去25年中，与天气有关的灾害占经济损失的80%左右。这是戏剧性的，特别是考虑到这个部门只生产ca。4%的GDP，同时为该国四分之一的人口提供生计。基于一个空间模型，本文测试了自然灾害的贡献，以催化整个墨西哥脆弱地区的移民过程。除了应付和适应能力外，我们还评估了1990年代灾害造成的经济损失加上不利的生产和贸易条件对引发向外移徙的影响。
The great human-environmental diversity of Mexico provides a framework for an initial understanding of the wide disparities between rich and poor. Mexico is still dominated in many regions by agriculture, and during the last 25 years, weather-related disasters have accounted for about 80% of economic losses. This is dramatic, especially considering that this sector produces only ca. 4% of GDP while providing a livelihood to one-quarter of the country’s population. Based on a spatial model, this paper tests the contribution of natural disasters to catalyzing the emigration process in vulnerable regions throughout Mexico. Besides coping and adaptive capacity, we assess the effect of economic losses from disasters in combination with adverse production and trade conditions during the 1990s in triggering out-migration.
