Nos primeiros meses de pandemia, as estatísticas indicam que as grandes cidades tornaram-se palcos destacados de contágio e disseminação da Covid-19. Diante desse cenário, o presente estudo oferece argumentos que auxiliam na construção e aferição preliminar de três hipóteses: a estrutura urbana e a organização das cidades interferem na taxa de distanciamento social e, portanto, no ritmo de contágio da doença; na cidade, a forma com que o sistema de transporte de pessoas está estruturado desempenha papel relevante no ritmo de disseminação da Covid-19; e a pandemia e as práticas de distanciamento físico e social alteram os padrões de mobilidade intraurbana. Analisam-se dados nacionais e regionais disponíveis em órgãos oficiais e outros trabalhos empíricos sobre a Covid-19 à luz de estudos teóricos sobre mobilidade urbana. Em seguida, por método indutivo, é feita uma associação destes dados aos diferentes modelos de cidades (compacta x espraiada), considerando, em especial, aspectos de mobilidade urbana. Os argumentos desenvolvidos nesse estudo parecem corroborar o teor central das hipóteses apresentadas. É preciso desenvolver modelos que incorporem estes elementos para avançarmos na compreensão da pandemia e, também, de elementos que auxiliem na construção de cidades mais resilientes a fenômenos como a Covid-19.

First, we construct a typology of municipalities through principal component analysis and cluster analysis. Using this typology, we seek to identify changing deforestation frontiers in the study area based not only on forest loss levels, but also on sets of socioeconomic and demographic elements associated with human development. We find four well-defined macro-deforestation frontiers that exhibit distinct interactions between forest loss and human development levels. Our results show different levels of demographic and economic pressures in these frontiers while revealing some important trends such as the internalization of investments and demographic growth in the arc of deforestation. In addition, population growth and in-migration and out-migration patterns in the explored municipalities suggest a demographic complementarity among frontiers. Finally, we explore implications for public policies seeking to advance forest recovery and long-term conservation through sustainable development growth at the local and regional levels.

Notwithstanding, the arising of small municipalities with more diversified economy, after having experimented decades of population decrease, indicates that the dispersion of the population exceeds the new metropolitan agglomerations and the medium cities of São Paulo’s countryside limits. The present study aims to somehow contribute to the comprehension of the lack of demographic concentration in the state, based on a proper methodology of population growth analyses and recent inter-state migratory movement mapping.

However, Amazonian urban networks have several characteristics that should be studied without "euphoria", because of some peculiarities that deserve to be explored in greater depth. Even though there is an urban hierarchy that seems to be similar to the other regions of the country, with clearly distinguishable regional and local centers, the various urban hierarchical levels have different demographic, spatial and socioeconomic dynamics. The fragility of the Amazonian urban networks is related to the creation of barriers for the flows of people, goods and services, like: a) the great distances that separate the capital cities from the other towns and hamlets; b) the lack of transport and communication infrastructure in large areas of the Amazon territory; c) the large proportion of the population without material and educational resources needed for them to actively participate in the various kinds of flows.

In this study, GoM uses several types of variables so as to improve the understanding of the greatness and power of Amazonian cities. To accomplish this task, a model that takes into account a variety of aspects, which exceed a purely economic or demographic analysis, is proposed. Understanding the hierarchical organization of the cities in the Amazon seems to be a very important exercise in order to understand the dynamics and specific characteristics of regional urban nets. In this way, it is evident that policies which stimulate the establishment of more structured urban nets in the Amazon are needed. A more balanced population distribution throughout the territory could bring a series of benefits, especially when it comes to the offer and access to all different sorts of services.
