ABSTRACT.
Uruguay is pursuing renewable energy production pathways using feedstocks from its agricultural sector to supply transportation fuels, among them ethanol produced from commercial technologies that use sweet and grain sorghum. However, the environmental performance of the fuel is not known. We investigate the life cycle environmental and cost performance of these two major agricultural crops used to produce ethanol that have begun commercial production and are poised to grow to meet national energy targets for replacing gasoline.
Using both attributional and consequential life cycle assessment (LCA) frameworks for system boundaries to quantify the carbon intensity, and engineering cost analysis to estimate the unit production cost of ethanol from grain and sweet sorghum, we determined abatement costs. We found 1) an accounting error in estimating N2O emissions for a specific crop in multiple crop rotations when using Intergovernmental Panel on Climate Change (IPCC) Tier 1 methods within an attributional LCA framework, due to N legacy effects; 2) choice of baseline and
crop identity in multiple crop rotations evaluated within the consequential LCA framework both affect the global warming intensity (GWI) of ethanol; and 3) although abatement costs for ethanol from grain sorghum are positive and from sweet sorghum they are negative, both grain and sweet sorghum pathways have a high potential for reducing transport fuel GWI by more than 50% relative to gasoline, and are within the ranges targeted by the US renewable transportation fuel policies.

ABSTRACT - A better understanding of the key characteristics influencing consumers' perception and purchase decisions of mandarins can contribute to the selection of new cultivars that assertively meet their needs and expectations, as well as to the development of strategies to increase mandarin consumption in the different markets. In this context, the aims of the present work were: i) to explore Uruguayan consumers' perception of mandarins, and ii) to identify the key characteristics that drive mandarin purchase decisions. A consumer study with 197 con-sumers was conducted in a supermarket in the metropolitan area of Montevideo (Uruguay). A word-association task was used to identify consumers' associations with mandarins, whereas a best-worst scaling was used to estimate the relative importance of specific characteristics. Results from the word association task revealed that sensory characteristics (juiciness, sweetness, color, flavor and odor) were the most salient concepts associated with a mandarin, followed by fruit characteristics and consumption context. Mandarin flavor was identified as the most important characteristic underlying consumers' purchase decisions in the best-worst scaling, followed by juiciness and high vitamin content; while packaging, size or price resulted less relevant. Consumer segments who attached different relative importance to vitamin content, price, lack of seeds and easiness to peel were identified. Results from the present work suggest that strategies to increase mandarin consumption should focus on sensory and hedonic aspects rather than package appearance or health-related oneS.

RESUMEN - Conocer las características de las mandarinas que más influyen en la percepción y la decisión de compra de los consumidores contribuye a la selección de nuevos cultivares que cumplan sus expectativas, así como las estrategias que promuevan su consumo en diferentes mercados. En este contexto, los objetivos de este trabajo fueron: i) explorar la percepción de las mandarinas por parte de los consumidores uruguayos, y ii) identificar las características que influyen en la intención de compra de mandarinas. Para ello, se desarrolló un estudio en un supermercado del área metropolitana de Montevideo (Uruguay) que incluyó 197 consumidores. Para identificar las características que el consumidor asocia con las mandarinas se utilizó el método de asociación libre, mien-tras que el método de escala mejor-peor (best-worst scaling -BWS) se aplicó para estimar la importancia relativa de determinadas características. Los resultados del primer estudio revelaron que las características sensoriales (jugosidad, dulzor, color, sabor y olor) fueron los conceptos más destacados asociados con las mandarinas, seguidos por características de la fruta y del contexto de consumo. El sabor fue identificado como la caracte-rística más importante que determina la intención de compra de los consumidores uruguayos, seguido por el contenido de jugo y de vitaminas, mientras que el envase, el tamaño del fruto o su precio resultaron menos relevantes. Se identificaron diferentes segmentos de consumidores que difieren en la importancia relativa del contenido de vitaminas, el precio, la ausencia de semillas o la facilidad de pelado. Los resultados del presente trabajo sugieren que los esfuerzos para promover el consumo de mandarinas deberían centrarse en aspectos sensoriales y hedónicos más que en aspectos relacionados con la apariencia o la salud.

RESUMO - O melhor entendimento das principais características que influenciam a percepção dos consumidores e as de-cisões de compra de tangerina pode contribuir para a seleção de novas cultivares que atendam de forma as-sertiva às suas necessidades e expectativas, bem como para o desenvolvimento de estratégias para aumentar o consumo de tangerina nos diferentes mercados. Nesse contexto, os objetivos do presente trabalho foram: i) explorar a percepção dos consumidores uruguaios sobre o mandarim e ii) identificar as principais características que orientam as decisões de compra do mandarim. Um estudo de consumidor com 197 consumidores foi con-duzido em um supermercado na região metropolitana de Montevidéu (Uruguai). Uma tarefa de associação de palavras foi usada para identificar associações de consumidores com mandarins, enquanto uma escala de melhor-pior foi usada para estimar a importância relativa de características específicas. Os resultados da tarefa de associação de palavras revelaram que as características sensoriais (suculência, doçura, cor, sabor e odor) foram os conceitos mais salientes associados a uma tangerina, seguida pelas características da fruta e contexto de consumo. O sabor da mandarim foi identificado como a característica mais importante subjacente às deci-sões de compra dos consumidores na escala melhor-pior, seguida por suculência e alto teor de vitaminas, enquanto a embalagem, tamanho ou preço resultaram menos relevantes. Foram identificados segmentos de consumidores que atribuíram importância relativa diferente ao teor de vitaminas, preço, falta de sementes e facilidade de descascar. Os resultados do presente trabalho sugerem que as estratégias para aumentar o con-sumo de tangerina devem focar nos aspectos sensoriais e hedônicos, e não na aparência da embalagem ou relacionados à saúde.
