Bioclimatic distribution and prevalence maps forFasciola hepatica in Espírito Santo State, Brazil J. Venom. Anim. Toxins incl. Trop. Dis.
Freitas,Deivid França; Martins,Isabella VF; Santos,Gleissy MADA dos; Santos,Alexandre R dos; Gomes,Daniel da Silva.
BackgroundFasciolosis affects different ruminant species and leads to great economic losses for cattle farmers worldwide. Thus, the current study aimed to evaluate bovine fasciolosis prevalence in the state of Espírito Santo, Brazil, using slaughter maps provided by slaughterhouses and verifying the origin of cattle.Methods : A map was created based on analysis of epidemiological data. The ArcGIS/ArcINFO 10.1 software was employed in order to elaborate updated bioclimatic maps that displayed the fasciolosis prevalence within the state – per city– between 2009 and 2011.ResultsAccording to the bioclimatic map it was clear that 52.24% of the state’s total area comprise regions considered favorable for the development and survival of Fasciola hepatica....

Cadastral maps of irrigated areas by center pivots in the State of Minas Gerais, using CBERS-2B/CCD satellite imaging REA
Ferreira,Elizabeth; Toledo,Joice H. de; Dantas,Antonio A. A.; Pereira,Rafael M..
Medium-resolution satellite images have been widely used for the identification and quantification of irrigated areas by center pivot. These areas, which present predominantly circular forms, can be easily identified by visual analyses of these images. In addition to identifying and quantifying areas irrigated by center pivot, other information that is associated to these areas is fundamental for producing cadastral maps. The goal of this work was to generate cadastral mapping of areas irrigated by center pivots in the State of Minas Gerais, Brazil, with the purpose of supplying information on irrigated agriculture. Using the satellite CBERS2B/CCD, images were used to identify and quantify irrigated areas and then associate these areas with a database...

Monitoring shoreline change using remote sensing and GIS: a case study of Kunduchi area, Tanzania OceanDocs
Makota, V.; Sallema, R.; Mahika, C..
Data from aerial photographs taken in 1981, 1992 and 2002 of the Kunduchi shoreline off the Dar es Salaam coast were integrated in a geographic information system (GIS) to determine shoreline change in that locality. It was found that considerable changes have taken place, and that the two techniques are effective for shoreline monitoring.

Origen y distribución espacial de metales pesados en suelos de Zimapán, Hidalgo. Colegio de Postgraduados
Duarte Zaragoza, Víctor Manuel.
Se realizó un estudio en los suelos de Zimapán, Hgo, cuyo principal objetivo de este trabajo fue conocer el origen y distribución espacial de metales pesados y diferenciar las aportaciones geogénicas derivadas de la actividad humana; en particular sobre la influencia de los depósitos de residuos de mina. La investigación se desarrolló en dos etapas, en la primera, se analizó el grado de contaminación de los suelos superficiales y se determinó la distribución espacial de los metales, usando un análisis geoestadístico. En la segunda etapa, se calculó la tasa de transporte eólico de los residuos de mina, mediante el uso de los modelos teóricos de Bagnold y Kawamura; además se evaluó la contaminación en función de la profundidad de los sitios más contaminados;...

Proposal for a territorial assessment of the effects of agricultural policies with a georeferred mathematical programming model: a case study AgEcon
Scozzafava, Gabriele; Casini, Leonardo.
Over the past fifteen years, the common agricultural policy (CAP) is profoundly changed under the pressure of European society and economic trends. The reforms of 2003-2004 marked a new phase in this path. This process continued with the reforms of the sugar (2006) and fruit and vegetables(2007) and is still ongoing with the recent proposals to reform the wine sector. The dynamics of consolidation, evaluation and redirection of the legislative measures adopted are very important and topical in view of the definition of the common agricultural policy. These issues on the political side emphasize the need for policy makers to have evaluative instruments witch can analyze both the effects on farmers behaviour and the effects generated in the territory....
