Belo Horizonte currently has several areas of social interest, which present irregular occupation and a lack of infrastructure. This scenario demands methodologies that can quickly respond to the main problems of the many areas, and that also contemplates a participatory planning. In this context, the article presents a Geodesign study conducted by the City Hall with the goal of evaluating the suitability of the methodology as a reference in the process of participatory planning for technicians and the population. It used a pilot area, called Maria Tereza, which is a relatively recent occupation located in the Northeastern region of the municipality.
The paper presents the study about the potential of the use of an interactive visualization tool, based on dynamic cartography, as resulting from the process of academic exercises on participatory planning. The case studies took place in 2015 in "Mirafori Sud", a neighborhood of the city of Turin, Italy, and in "Pampulha", a district of Belo Horizonte, Brazil. In both cases, the interactive visualization of maps was used for information gathering, sharing information and knowledge production among different target audiences.
The study area was surrounding Córrego do Feijão Mine, located in the city of Brumadinho/MG, Brazil. From this proposal, we present the analysis of the effect of disruption of one of the tailings dams of the Córrego do Feijão Mine, which took place in January 2019, under the responsibility of Vale S.A. The rupture culminated in mud flow. A study and characterization of the area was made, to understand the flow of the waters, and consequently, the mud. In addition, it was possible to obtain information on the land use of the area before and after the break using remote sensing (Sentinel-2A) supervised image classification. Through a spatial and temporal analysis, it was estimated that the mud reached a total of 2.48 km

, being the class of robust vegetation the most affected by the disaster in numerical terms. The typology of anthropic areas, despite being the smallest area hit by mud, was the one that suffered the greatest impact. The importance of an analysis of the elements that belong in the area of study and how they behave, in order to avoid and mitigate situations of vulnerability is considered very important. Finally, it is emphasized the relevance of a spatial planning studies that considers the integrated planning between the juxtaposition of human activities, social and spatial relations and their various impacts on the landscape.
This article aims to present a Methodological Guide to add gamification elements to the Geodesign framework when planning the future of the city, using Geogames such Minecraft, with the participation of children in Tirol, in Brazil. The problematic tackled is related to the challenges that participants of a Geodesign workshop face when co-designing projects as alternative futures for the territory, such as losing engagement and involvement. To support the participants overcome these challenges we incorporate playfulness into the some of the Geodesign workshop phases enhancing geovisualization, collaboration and cognition.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
