Stranding of oceanic-pelagic elasmo branchs in the southeastern Brazil are reported. Data comes from animals observed in the coast of São Paulo state, between 1999 and 2012. Nine individuals of two species were recorded: Pteroplatytrygon violacea (n = 5; mostly during the winter) and Isurus oxyrinchus (n = 4; two in the winter and two in the summer). For P. violacea the strandings restricted to the austral winter suggest that the species follows the intrusion of high temperatures water masses recorded in southeastern Brazil during this season, bringing some individuals to shallow waters. For I. oxyrinchus is possible that individuals escaped from hooks of the commercial pelagic long line fishery and suffered injuries in the esophagus and in the gastric wall, stranding due to difficulties in locomotion and feeding. As these stranded sharks were not necropsied and only two animals were observed during the austral summer, we cannot exclude other causes of beaching such diseases or the intrusion of cold water masses in the continental shelf during this season.

In managing water resources, indexes are used to simplify and quantify available information as well as report the characteristics of a region under study. These indexes may be extremely demanding concerning information required, or very simple, and the water poverty index and Falkenmark index are examples of both extreme situations, respectively. Searching for an index that considers regional and local complexities and information available in developing countries, a new index was developed to evaluate the population accessibility to water resources. This new index combines the Human Development Index and Falkenmark Index and geographic information systems. The results are presented in figures which show the situation at national level, highlighting that the Northeast and Southeast regions are the most vulnerable in Brazil.
