15. Veículos de tração animal no Distrito Federal : dos invisíveis ao paradigma da governança ambiental como trilha para construção de um ideário socioambiental e respeito a todas as formas de vida
The Federal District (DF) is an example of contradictions and contrasts emerging from migration processes that led to an increase in the population density and expansion of urban areas - a landscape which is a byproduct of a perverse paradigm of economic development. Part of the internal migrants, which were excluded from the formal labor sector, appeal to t

16. Ecomigrantes, refugiados ou deslocados ambientais: populações vulneráveis e mudança climática
Droughts, floods, severe storms, melting ice caps and consequent rise in sea level are some of the consequences of climate change. Concerning the human side of the climate change, some experts estimate that 200 million to 250 million people will be forced off their land by mid-century and the European Union itself has already established that migration press

19. Predicting population level of Delphacodes kuscheli, vector of Mal de Río Cuarto virus, and climate risk in the Argentine Pampas using meteorological models
The planthopper Delphacodes kuscheli Fennah (Hemiptera: Delphacidae), principal insect vector of Mal de Río Cuarto virus on corn in Argentina, produces severe disease outbreaks when migration of large macropterous populations coincides with early corn growth stages. Linear models based on winter environmental variables were developed to explain variation of

22. The role of population movement in the epidemiology and control of schistosomiasis in Brazil: a preliminary typology of population movement
This paper examines recent developments in migration studies. It reviews literature related to the potential role of internal population movement in the occurrence of schistosomiasis in Brazil and modifies Prothero's typology of population movement for use in Brazil. This modified classification system may contribute to a better understanding of schistosome
