Using different proxies to predict hantavirus disease risk in São Paulo state, Brazil
Recent studies predict disease risk using different proxies, such as pathogen prevalence in hosts, abundance of the main hosts, and the number of reported disease cases. These proxies are used to build risk maps that can ...
Mapping hazard risk: A case study of Ubatuba, Brazil
Steep slopes in subtropical zones are always at risk from landslides. The risk greatly increases when there is rapid, unplanned urban growth. This has happened at Ubatuba on the Brazilian coast - tourism-related development ...
Landslide Hazard and Risk Zonation Mapping in the Río Grande Basin, Central Andes of Mendoza, Argentina
(Mountain Research & Development, 2002-05)
This paper presents an inventory of landslides and hazard and risk zonation mapping along the Río Grande basin in the Central Andes of Mendoza. The mapping was based on field work combined with interpretation of aerial ...
Identifying elements at risk from openstreetmap: the case of flooding
(The Pennsylvania State UniversityUniversity ParkPennsylvania, 2014-05-18)
The identification of elements at risk is an essential part in hazard risk assessment. Especially for recurring natural hazards like floods, an updated database with information about elements exposed to such hazards is ...
Hantavirus risk maps for Conguillio National Park, Southern Chile
(SOC BIOLGIA CHILE, 2007)
Participatory risk mapping of malaria vector exposure in northern South America using environmental and population data
Malaria elimination remains a major public health challenge in many tropical regions, including large areas of northern South America. In this study, we present a new high spatial resolution (90 × 90 m) risk map for Colombia ...
A classification methodology for the risk of weed infestation using fuzzy logic
Despite modern weed control practices, weeds continue to be a threat to agricultural production. Considering the variability of weeds, a classification methodology for the risk of infestation in agricultural zones using ...
Mapping of risk and susceptibility of shallow-landslide in the city of Sao Paulo, Brazil
(ELSEVIER SCIENCE BVAMSTERDAM, 2012)
In the city of Sao Paulo, where about 11 million people live, landslides and flooding occur frequently, especially during the summer. These landslides cause the destruction of houses and urban equipment, economic damage, ...
Mapping soil pollution by spatial analysis and fuzzy classification
Spatial analysis and fuzzy classification techniques were used to estimate the spatial distributions of heavy metals in soil. The work was applied to soils in a coastal region that is characterized by intense urban occupation ...
