    Developing an Agro-Ecological Zoning Model for Tumbleweed (Salsola kali), as Energy Crop in Drylands of Argentina
    (2016) Falasca, Silvia; Pitta-Álvarez, Sandra; Ulberich, Ana Cristina
    Salsola kali is considered extremely valuable as an energy crop worldwide because it adapts easily to environments with strong abiotic stresses (hydric, saline and alkaline) and produces large amounts of biomass in drylands. This species is categorized as an important weed in Argentina. The aim of this work was to design an agro-ecological zoning model for tumbleweed in Argentina, employing a Geography Information System. Based on the bioclimatic requirements for the species and the climatic data for Argentina (1981–2010 period), an agro-climatic suitability map was drawn. This map was superimposed on the saline and alkaline soil maps delineated by the Food and Agriculture Organization for dry climates, generating the agro-ecological zoning on a scale of 1 : 500 000. This zoning revealed very suitable and suitable cultivation areas on halomorphic soils. The potential growing areas extend from N of the Salta province (approximately 22° S) to the Santa Cruz province (50° S). The use of tumbleweed on halomorphic soils under semi-arid to arid conditions, for the dual purpose of forage use and source of lignocellulosic material for bioenergy, could improve agricultural productivity in these lands. Furthermore, it could also contribute to their environmental sustainability, since the species can be used to reclaim saline soils over the years. Based on international bibliography, the authors outlined an agro-ecological zoning model. This model may be applied to any part of the world, using the agro-ecological limits presented here.

    Industrias de fundición: aspectos ambientales e indicadores de condición ambiental
    (2013) Sosa, Beatriz Soledad; Banda Noriega, Roxana Bettina; Guerrero, Elsa Marcela
    El empleo de indicadores ambientales es, actualmente, una herramienta que colabora en el proceso de toma de decisiones en la gestión de la administración pública y privada. La falta de antecedentes de Indicadores de Condición Ambiental (ICA) en lo regional y local, la información asociada a la generación de residuos, efluentes y emisiones gaseosas provenientes de la industria de fundición, y la particularidad de encontrar a estas industrias en el ámbito urbano en la ciudad de Tandil, Argentina, orientan el principal objetivo del presente trabajo: la construcción de un conjunto de ICA que proporcionen información sobre el estado del ambiente en relación a este tipo de actividad. El campo de la investigación comprendió el total de industrias de fundición de la ciudad en el periodo marzo – abril de 2010. Se generaron ICA para el recurso, aire (9), suelo (5) y agua (1) con metodología adaptada a cada caso particular.

    Patrimônio industrial e turismo: análise de potencialidade e proposta de circuito de turismo industrial em Barracas, Buenos Aires, Argentina
    (2016) Guzmán Ramos, Aldo; Fernández, Guillermina; Basavilbaso, Héctor; Bordoli, Mariana
    O desenvolvimento industrial na Argentina iniciado a finais do século XIX e que sofreu a queda a partir da década de 1970 deixou numerosos bens imóveis e móveis, em grande parte do território nacional. O mesmo é fatível de re-utilizar através do turismo industrial como um mecanismo para reativar económica e socialmente espaços abandonados e em crise, mas também como uma forma de revitalizar a identidade e cultura, para recuperar uma parte da história. A metodologia de tipo exploratória e descritiva implicou um relevamento dos bens industriais localizados no bairro de Barracas da cidade de Buenos Aires, Argentina. Aplicando variáveis para determinar o estado e a potencialidade turístico-recreativa mediante usando uma escala de Likert. Como resultado selecionaram-se 68 locais dos quais através da aplicação das variáveis ficaram 24 locais, que foram organizados para desenvolver um circuito de turismo industrial que poderia permitir complementar a oferta de turismo cultural em Buenos Aires.

    Water Footprint and Virtual Water Trade of Maize in the Province of Buenos Aires, Argentina
    (2021) Arrien, María Macarena; Aldaya, Maite M.; Rodríguez, Corina Iris
    Agriculture is the largest fresh water consuming sector, and maize is the most produced and consumed crop worldwide. The water footprint (WF) methodology quantifies and evaluates the water volumes consumed and polluted by a given crop, as well as its impacts. In this work, we quantified for the first time the green WF (soil water from precipitation that is evapotranspired) and the green virtual water exports of maize from Buenos Aires province, Argentina, during 2016–2017, due to the relevance of this region in the world maize trade. Furthermore, at local level, we quantified the green, blue (evapotranspired irrigation), and grey (volume of water needed to assimilate a pollution load) WF of maize in a pilot basin. The green WF of maize in the province of Buenos Aires ranged between 170 and 730m3/ton, with the highest values in the south following a pattern of yields. The contribution of this province in terms of green virtual water to the international maize trade reached 2213 hm3/year, allowing some water-scarce nations to ensure water and water-dependent food security and avoid further environmental impacts related to water. At the Napaleofú basin scale, the total WF of rainfed maize was 358 m3/ton (89% green and 11% grey) and 388 m3/ton (58% green, 25% blue, and 17% grey) for the irrigated crop, showing that there is not only a green WF behind the exported maize, but also a Nitrogen-related grey WF.
