In Brazil, the Semi-arid is the poorest region in the country, where a significant part of the population is not adapted to drought and fluctuations in rainfall. Based on multivariate methods, I investigate here the spatial patterns of drought and socioeconomic variables between 2000 and 2010 within the Brazilian Semi-arid. In this work, I find five well-defined socio-environment clusters presenting distinct characteristics: developing cluster, demographic gains cluster, stagnated cluster, socio-environmental challenges cluster and undeveloped cluster. My results show that there are vast areas in the Brazilian Semi-arid that demand development strategies and deep structural changes. Policies for development and poverty alleviation focused essentially on increasing income will not necessarily have an immediate impact on other important social indicators, such as mortality and illiteracy rates. Multidimensional approaches and multiscale interventions considering partnerships among all levels of government (local, state and federal) are essential to overcome this vicious cycle linking environment constrains with poverty and low development levels. Finally, this paper shows that integrating socioeconomic, demographic and environmental indicators is vital to understanding development patterns throughout the Brazilian Semi-arid.

在巴西，半干旱地区是该国最贫困的地区，那里的很大一部分人口无法适应干旱和降雨波动。基于多元方法，我在这里调查了 2000 年至 2010 年巴西半干旱地区干旱和社会经济变量的空间格局。在这项工作中，我发现五个定义明确的社会环境集群呈现出不同的特征：发展集群、人口增长集群、停滞集群、社会环境挑战集群和未开发集群。我的研究结果表明，巴西半干旱地区有广阔的地区需要发展战略和深刻的结构变化。主要侧重于增加收入的发展和减贫政策不一定会对死亡率和文盲率等其他重要社会指标产生直接影响。考虑到各级政府（地方、州和联邦）之间的伙伴关系的多维方法和多尺度干预对于克服将环境限制与贫困和低发展水平联系起来的这种恶性循环至关重要。最后，本文表明整合社会经济、人口和环境指标对于了解整个巴西半干旱地区的发展模式至关重要。州和联邦）对于克服这种将环境限制与贫困和低发展水平联系起来的恶性循环至关重要。最后，本文表明整合社会经济、人口和环境指标对于了解整个巴西半干旱地区的发展模式至关重要。州和联邦）对于克服这种将环境限制与贫困和低发展水平联系起来的恶性循环至关重要。最后，本文表明整合社会经济、人口和环境指标对于了解整个巴西半干旱地区的发展模式至关重要。
