Item Landslide susceptibility mapping using the statistical method of information value : a study case in Ribeirão dos Macacos basin, Minas Gerais, Brazil.(2021) Rosa, Mateus Lima; Sobreira, Frederico Garcia; Barella, Cesar FalcãoThis research study was developed in the Ribeirão dos Macacos basin at the district of Nova Lima, Minas Gerais state, Brazil. The information value statistical method was applied in the construction of the landslide susceptibility map at the 1:25,000 scale. Different partitions of the inventory were tested, as well as different landslide predisposing factors. In the construction of the landslide inventory, the south, southeast and south-west slopes generally present a higher quality in aerial / orbital images due to the position of the sun (lighting direction), which emphasizes the surface structures and it may omit old landslides on slopes facing north, northeast, and northwest. This condition can generate misleading models when using the slope aspect. Another verifi cation was that the models with better Area Under the Curve index will not always restrict the high susceptibility class in smaller areas. This incongruence occurs due to the different curve conformations, since a smaller index curve can present more restrictive results than a larger index curve. The results showed that the model has a high capacity of adjustment to the input data and high landslide predictive capacity.Item The emergency law : is it able to create a DRM system in Brazil?(2018) Gouveia, Antônio Maria Claret deBrazil is increasingly impacted by natural disasters, forcing the Federal Government to improve the current disaster risk management (DRM) system. After the two big disastrous events of Nova Friburgo, RJ and of Vale do Itajaí, SC, during 2011, Brazilian Congress approved a new Emergency Law which is supposed to be the cornerstone of a Brazilian DRM system. The main purpose of this paper is to investigate how much this law is able to produce effective results in this direction. The methodology adopted is the hermeneutics analysis of the law text itself and of its reference texts but focus is on its engineering concepts and on the disaster management method proposed. United Nations International Strategy for Disaster Reduction priorities for action in the period 2005-2015 are taken as a reference. Conclusions suggest that a revision of the current Brazilian Emergency Law is needed and key aspects for this revision are described.
