The techniques provided by spatial analysis have become a great ally of tourist planning as they allow the carrying out of exhaustive territorial analyses. The greater availability of georeferenced databases together with the more and more extensive use of GIS (Geographic Information Systems) is materialising in the proliferation of studies analysing the distribution patterns of tourist territories. The present study uses these techniques to study the degree of equilibrium in the distribution of places and its level of occupation in a region where the use of expansionary policies of growth of the tourism sector has been able to cause a strong imbalance in said activity, i.e., the case of the region of Extremadura. To verify this, both global contrasts, global Moran’s I and G (d) of Getis and Ord, are used, as well as local contrasts, to map LISA (Local Indicators of Spatial Association). The results obtained confirm the existence of strong imbalances in the effectiveness of the places created while allowing the identification of different clusters of high and low values. These findings represent an important output for the strategic planning of the territory in order to develop a strategy that allows the sustainable tourism development of the territory.

Planted forests have grown substantially in Brazil, especially in states such as Goias. While they may compete with native forest areas, planted forests also present themselves as economically viable solutions for the recovery of degraded areas. This study presents the market of wood in the Brazilian state of Goias analyzing the interaction between supply and demand curves of the product in a partial equilibrium analysis. In this sense, it is essential to understand the spatial issue to offer production by planning the transaction costs related to transportation. Therefore, the distribution of companies is linked to the production chain, mapped by means of labor market bases (Ministry of Labor), wood production (IBGE) and other industry data. The spatial analysis of the planted forest area (silviculture) in Goias between 2000 and 2016 was based on data from the time series, from mapping provided by the MapBiomas Project. In Goias, considering all sectors of the forest production chain, in 2015 alone, revenues exceeded US$ 1.24 billion and public collections US$ 24 million, employing more than 36 thousand people in 7 thousand firms. Thus, it is fundamental to understand this process, identifying the main determinants of planted forests, through statistical and spatial analysis. From a spatial point of view, planted forests and companies involved in wood production are relatively spread throughout the state, except for the state capital of Goiania, which has a large number of timber trade and manufacturing firms.

Natural resources, as the material basis of human life and production, play a crucial role in national economic and social development. It is essential to reveal the structural characteristics of global natural resource supply and demand, which has become one of the most critical factors affecting every country’s policy strategy and economic development. However, mining the characteristics of international natural resource trades is a huge challenge because of the availability and quality of trade data. In this study, the international natural resource trade system is modeled as networks based on the available bilateral trade data from 2000 to 2016. Complex network methods and spatial analysis are utilized to explore the networked and spatial characteristics of different international natural resource trade networks (INRTNs). First, we quantitatively present the overall evolution trend of INRTNs by calculating several indicators of network features at the macrolevel. Then, as the intermediate-level characteristics of INRTNs, the core–periphery structures are explored by applying hierarchical clustering and a visual matrix heatmap. Finally, at the microlevel, the imbalance in direction is detected through the combination of node importance in a complex network with bivariate choropleth maps of spatial analysis. The empirical evidence from INRTNs of different product types in this paper will help governments and business administrations to perceive the complex natural resource trade environment, which can instruct policymakers to formulate effective import–export policies and ensure national resource security and sustainable development.

The aim of this research was to assess–based on spatial analysis techniques and expert knowledge–the capacity of land covers to provide ecosystem services (ES) in the socioecological system (SES) “metropolitan area of influence of Cali”. In this manner, it was possible to identify the metropolitan ecological structure of said SES in order to establish a baseline from which its level of conservation or fragmentation can be identified in the future. The application of the methodology required the use of mixed research methods. In this regard, i) the SES area was defined from the combination of urban-functional and ecological-biophysical criteria; ii) criteria were defined to establish the unit of analysis and the land cover classification of the defined area at 1:25,000 scale; and iii) the assessment of ES was made based on a consultation with experts from academic, administrative and scientific institutions about the capacity to supply and demand ES present in the land covers that make up the SES. It was found that the metropolitan ecological structure is composed of ten natural and semi-natural land covers, which have the capacity to provide cultural ES (high level), regulation ES (high and medium levels) and supply ES (low level). In addition, as expected, the perception was validated that the flat area of the SES–which concentrates productive, economic and service activities–is clearly the demanding one, while the areas located in the periphery–i.e. piedmonts and the Eastern and Western mountain chains–are the suppliers. Finally, the results of this research once again demonstrate that, from the academic angle, there are novel ways to strengthen the processes of formulating guidelines for planning and environmental management of metropolitan SES, from the combination of spatial analysis and expert knowledge.
