本研究分析了在非洲背景下(布基纳法索、西非)造成省际移徙的因素，特别侧重于环境因素在推动生态边缘地区大规模移徙方面的作用。它使用统计方法模拟移徙数据，以评估社会人口和生物物理变量的相对重要性。前者包括男性人口比例、识字率和经济活动率，以及重新安置政策的存在。后者包括对土地退化、土地可获得性和气候变异性的衡量，这些指标在该国不同地区之间差别很大。结果表明，正如预期的那样，各省的人口和社会经济特征与移徙模式有关，环境变量也很重要。然而，环境变量在解释移徙中的贡献略低于社会人口变量。结果表明，布基纳法索的跨省移徙受到以下因素的影响：原籍和目的地的识字率和经济活动率高，原籍男子比例高，目的地男子比例低，以及原籍地降雨量变化、土地退化和土地可获得性等不利条件，以及目的地对这些变量有利的条件。(C)2003爱思唯尔有限公司。保留所有权利。
This study analyses the factors that cause inter-provincial migrations in an African context (Burkina Faso, West Africa), focusing specifically on the role of environmental factors in driving large migration flows in ecologically marginal regions. It uses statistical methods for modelling migration data to assess the relative importance of socio-demographic and biophysical variables. The former included the percentage of the population who are male, literacy and economic activity rates, and the presence of a resettlement policy. The latter included measures of land degradation, land availability and climatic variability, which vary considerably between different regions of the country. The results demonstrate that, as expected, demographic and socio-economic characteristics of Provinces were associated with migration patterns, and that environmental variables were also significant. However, the contribution of environmental variables in the explanation of migration was slightly lower than for the socio-demographic variables. The results show that inter-provincial migrations in Burkina Faso are influenced by high literacy and economic activity rates at the origin and destination, a high proportion of men at the origin, a low proportion of men at the destination, as well as by unfavourable conditions concerning rainfall variability, land degradation and land availability at the origin, and favourable conditions at the destination for these variables.
