“…A transição demográfica da população para as cidades demanda uma maior pressão sobre os recursos naturais disponíveis em sua área de abrangência, seja por alimentos, seja por recursos energéticos ou naturais (extração de materiais para a construção civil). Municípios que sofrem mudanças no número de habitantes em um dado período podem apresentar alterações no uso do solo do seu território, tanto em áreas urbanizadas, quanto em seus arredores (Rufino & Silva, 2017). Desta forma, esta variação do contingente populacional aumenta a demanda de recursos, a densidade demográfica e reflete o crescimento desordenado, comum em muitos centros urbanos.…”

A dengue tem sido uma preocupação constante na área da saúde pelas características endêmicas e virais da doença tornando-a um problema de saúde pública. Este estudo teve como objetivo descrever indicadores para a ocorrência da dengue em municípios da região Oeste de Santa Catarina. Trata-se de uma pesquisa quantitativa de caráter descritivo-transversal. A investigação ocorreu no segundo semestre de 2017 em quatro municípios (Chapecó, Descanso, Pinhalzinho e São Miguel do Oeste), que apresentaram os maiores índices de incidência de dengue no ano de 2016. Foi realizada uma busca em dados secundários na base de dados virtual do DataSus e do Instituto Brasileiro de Geografia e Estatística (IBGE) referentes aos municípios pesquisados rastreando informações sobre cobertura da Estratégia de Saúde da Família, índices de emprego e desemprego, escolaridade, Índice de Desenvolvimento Humano, saneamento básico, cobertura da rede de esgoto, gestão de resíduos, tratamento da água e taxa de urbanização. Observou-se déficits no sistema de esgotamento sanitário e percentual abaixo do esperado para a avaliação do IDEB no Ensino Médio. A urbanização acelerada favorece o aparecimento de situações que contribuem para a ocorrência de dengue. Indicadores como IDH, cobertura adequada da ESF podem ser fatores de proteção e prevenção da dengue.

“…In these places, the population density was not accompanied by the expansion of public services infrastructure, fostering urban agglomerations with poor living standards than the national average, while the countryside remained lacking investments [83]. However, underneath this apparent homogeneity, local dissimilarities still emerge as identified by other authors for economic, land use, and health indicators [13,14,[84][85][86][87]. Factor 1 ends up locally reflecting this bigger picture where poor human well-being and social/health inequalities are observed for the whole Semiarid region, strongly distancing it from the patterns observed for other Brazilian regions, while highlighting its local differences.…”

Health determinants might play an important role in shaping the impacts related to long-term disasters such as droughts. Understanding their distribution in populated dry regions may help to map vulnerabilities and set coping strategies for current and future threats to human health. The aim of the study was to identify the most vulnerable municipalities of the Brazilian semiarid region when it comes to the relationship between drought, health, and their determinants using a multidimensional index. From a place-based framework, epidemiological, socio-economic, rural, and health infrastructure data were obtained for 1135 municipalities in the Brazilian semiarid region. An exploratory factor analysis was used to reduce 32 variables to four independent factors and compute a Health Vulnerability Index. The health vulnerability was modulated by social determinants, rural characteristics, and access to water in this semiarid region. There was a clear distinction between municipalities with the highest human welfare and economic development and those municipalities with the worst living conditions and health status. Spatial patterns showed a cluster of the most vulnerable municipalities in the western, eastern, and northeastern portions of the semiarid region. The spatial visualization of the associated vulnerabilities supports decision making on health promotion policies that should focus on reducing social inequality. In addition, policymakers are presented with a simple tool to identify populations or areas with the worst socioeconomic and health conditions, which can facilitate the targeting of actions and resources on a more equitable basis. Further, the results contribute to the understanding of social determinants that may be related to medium- and long-term health outcomes in the region.

“…Guillermo Heider held that water is a key resource that affects decision-making in drylands, so from the perspective of hydrology and ecological science, he analyzed the land use of semi-arid areas by former Hispanics living in central Argentina, and discussed the spatial distribution and mobility of population in drylands [39]. According to the analysis by GIS (Geographic Information System) and geographic detector, Rufino believed that human activities and population dynamics are the main causes of land use changes in Brazil's semi-arid areas, and areas around major cities are undergoing more dramatic changes and are under greater pressure [40]. Taking Jinta Oasis in China as an example, Shanzhong Qi analyzed that the sustained growth of population and livestock leads to serious environmental degradation problems in the oasis, such as land pollution, desertification, degradation of water environment, and vegetation degradation [41].…”

Population migration is a major event of optimizing the allocation of production factors and a key way to construct regional relations and promote spatial reconstruction. However, there are few papers published on population migration that have a direct impact on the sustainable development of deserts owing to the more sensitive and complex man–earth relationship. Therefore, it is important to study the laws and characteristics of population migration in such regions. The study of Egypt by Zipf’s law shows that the spatial distribution of migration population size conforms to the law of power function with fractal characteristics of different types. The migration population is generally in a “Pareto” state in spatial distribution. Decentralization power is the leading driving force of spatial distribution, and scale-free regional distribution shows significant spatial agglomeration and gradient. Limited by research scope and “heavy tail” factors, Zipf’s law is not completely applicable. The spatial pattern and flow field characteristics of the migration population are analyzed in this paper by the conversion from “structural fractal” to “spatial fractal” based on scale-free geographic projection, providing the reference for the formulation of population governance policies and spatial planning strategies in Egypt and more desert countries.
