Item type:Publication, A review of root, tuber and banana crops in developing countries: past, present and future(Wiley, 2020-09-16)For many of the developing world's poorest farmers and food-insecure people, roots, tubers, bananas and plantain crops (RTBs) serve as a critical source of food, nutrition and cash income. RTBs have been particularly important in areas where local agri-food systems are under stress. Under such circumstances, growers, processors and traders often see opportunities to improve food security or increase their incomes with those crops due to shifting tastes and preferences for food and non-food products. Since the early 1990s, cassava output surged in sub-Saharan Africa, while potato production expanded rapidly in Asia. RTBs are consumed by over three billion people in developing countries with a market value of US$ 339 billion. This paper analyses the major changes in production, utilisation and trade of RTBs over the last six decades, assesses estimates of their future trajectory and offers recommendations so that they might achieve their full potential. - Some of the metrics are blocked by yourconsent settings
Item type:Publication, The influence of ethnic identity on Peruvian quinoa consumption: a top Lima and modern metropolitan Lima approach(BioMed Central Ltd, 2022-12-01)The International Year of Quinoa (IYQ) (2013) showcased quinoa to the world and generated a rapid expansion in international demand for quinoa. It also increased the level of consumption in Peru. Peruvian ethnic identity reflects the food culture of origin. This research aims to determine the relationship between ethnic identity and other Theory of Planned Behavior factors on quinoa consumption intention and frequency of consumers in Top Lima and Modern Metropolitan Lima, Peru. A survey of 381 respondents was conducted between April and September 2017, and structural equation modeling was used to analyze the data. Contrary to expectations, intention and frequency of consumption of quinoa were negatively affected by “ethnic identity” (p < 0.05). This result is related to the promotion by the IYQ and Marca Perú (brand name Peru) and the gastronomic boom. - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Growth, innovation, and policy for chicken in Latin America 1961–2019(Wiley, 2022-03-24)Summary Motivation Latin America has witnessed massive increases in production and consumption of chicken meat over the last 60 years and well beyond its share of the developing world's population. Chicken is now a major source of livestock protein in regional diets; leads livestock production in 25 out of the region's 33 countries; production, slaughtering, and sales provide millions of jobs. Purpose To analyse growth rates for chicken meat in Latin America, why they have differed, how the role of innovation and development policies contributed to bringing about this growth, in turn leading to the patterns of governance of these activities today. Methods and approach This study used a modified value chain framework along with FAO statistics, national data, published and unpublished studies to analyse macro‐level developments and their linkages to shifts in the organization of activities in the value chain for chicken from pre‐production through to consumption and trade from past to present. Findings Different natural resource endowments, demographics, and dietary preferences combined with frequent innovations and an array of policy measures led to a spectacular surge in output and productivity, lower costs, and facilitated a steady rise in consumption. As part of that growth, these activities became increasingly concentrated in Brazil, Mexico, and Peru and within those countries in a few very large firms. Their operations expanded in the value chain beyond the farm gate, across the region, and in some cases around the world. Policy implications This paper has implications for greater transparency in grower contracts, better working conditions for slaughterhouse workers and bird catchers, more environmentally and bird‐friendly chicken production, accelerated adoption of practices as per Principles for Responsible Investment in Agriculture and Food Systems in the value chain for broilers in Latin America and the Caribbean, and improved enforcement of laws and regulations governing the technical and financial operations of value chains for chicken, along with renewed collaboration among government authorities to that effect. - Some of the metrics are blocked by yourconsent settings

Item type:Publication, Responsible consumption trend in Generation Z and millennials: Its impact on SDG 12. A Peruvian case study(Emerald Publishing, 2024-10-09)This study aims to analyze the responsible consumption of Generation Z and millennials in the Latin American market, with special emphasis on the Peruvian case, to identify their differences with consumers born in 1980 and earlier and to evaluate their contribution to Sustainable Development Goal 12. Design/methodology/approach: The study was conducted on a sample of 309 persons living in Lima. After developing and validating an instrument, an online questionnaire was used to collect data. These data were analyzed descriptively and inferentially, using chi-square tests to validate the relationship between variables. Findings: The study identifies and explains the new trend of responsible consumption among Generation Z and millennials in emerging markets, where end consumers interact with and prefer products and services from companies that demonstrate responsible behavior and offer trust. It identifies new consumption variables that go beyond the traditional ones. Research limitations/implications: The study reveals a trend in the responsible consumption of Generation Z and millennials in Peru. However, it is necessary to complement the study in other countries in the region, as well as to study the new generations, such as the alpha generation and their consumption patterns. Practical implications: The new trend of responsible consumption among Generation Z and millennials is forcing companies to implement strategies and develop corporate social responsibility programs. These companies must demonstrate ethical, environmental, socially responsible and sustainable behaviors in their daily operations to satisfy their stakeholders. Originality/value: The study reveals a new trend in Peru, a developing country, where the market – the end consumer – is more informed and therefore demands better corporate performance from companies, including care for the environment and a contribution to society that includes a good relationship with its stakeholders. - Some of the metrics are blocked by yourconsent settings
Item type:Publication, George Ritzer: The man, the sociologist, the legend(SAGE Publishing, 2025-12-01)This Festschrift honors the enduring legacy of George Ritzer, one of sociology's most influential and recognizable figures. Ritzer's scholarship has helped shape core areas of the discipline—ranging from consumption and social theory to globalization and beyond—while also generating new conceptual terrains such as McDonaldization, prosumption, and the study of “nothing” and “something.” The Festschrift opens with a biographical essay authored by Ritzer himself, highlighting his unconventional path to becoming one of the leading figures in sociology. Beyond his published work, Ritzer has shaped the field through founding key academic outlets, editing influential reference works, mentoring numerous scholars, and inspiring broad audiences by translating complex ideas from the ivory tower into concepts that can be more easily understood.2 - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Development and Validation of a Methodology for Predicting Fuel Consumption and Emissions Generated by Light Vehicles Based on Clustering of Instantaneous and Cumulative Vehicle Power(Multidisciplinary Digital Publishing Institute (MDPI), 2025-03-01)In the global context, transportation contributes 26% of the total CO2 emissions, with land transport responsible for 92% of the emissions within the sector. Given this significant contribution to climate change, it is crucial to quantify vehicular impacts to implement effective mitigation strategies. This study introduces an innovative method for predicting fuel consumption and emissions of carbon monoxide, hydrocarbons, and nitrogen oxides in vehicles, based on instantaneous vehicle-specific power (VSP) and mean accumulated power. VSP is a parameter that measures a vehicle's power in relation to its mass, providing an indicator of the efficiency with which the vehicle converts fuel into motion. This indicator is particularly useful for assessing how vehicles utilize their energy under different driving conditions and how this affects their fuel consumption and emissions. Using data collected from 10 vehicles over 2000 h and covering altitudes from 0 to 4000 m above sea level in Ecuador, the method not only improved the accuracy of consumption predictions, reducing the margin of error by up to 10% at high altitudes, but also provided a detailed understanding of how altitude affects both consumption and emissions. The precision of the new method was notable, with a standard deviation of only 0.25 L per 100 km, allowing for reliable estimates under various operational conditions. Interestingly, the study revealed an average increase in fuel consumption of 0.43 L per 1000 m of altitude gain, while CO2 emissions showed a significant reduction from 260.93 g/km to 215.90 g/km when ascending from 500 m to 4000 m. These findings underscore the relevance of considering altitude in route planning, especially in mountainous terrains, to optimize performance and environmental sustainability. However, the study also indicated an increase in CO and NOx emissions with altitude, a challenge that highlights the need for integrated strategies addressing both fuel consumption and air quality. Collectively, the results emphasized the complex interplay between altitude, energy efficiency, and vehicular emissions, underscoring the importance of a holistic approach to transportation management, to minimize adverse environmental impacts and promote sustainability.1 - Some of the metrics are blocked by yourconsent settings
Item type:Publication, ¿A quién se le ocurre escribir con guantes? Objetos, consumo, circulaciones y subversiones en Mi vida con Enrique Gómez Carrillo (1929), de Aurora Cáceres(Autonomous University of Barcelona, 2026-07-13)Mi vida con Enrique Gómez Carrillo (1929) es un texto autobiográfico en el que convergen distintas textualidades que revelan los desafíos planteados por Aurora Cáceres al campo literario y sus sistemas de clasificación. Siguiendo la lectura del texto como una crónica modernista a contrapelo, me detengo en la dimensión material: el mundo de los objetos y sus circulaciones, clave para el desmontaje que plantea Cáceres del imaginario del artista modernista, excluyente frente a las mujeres. La foto que le envía Gómez Carrillo a Cáceres, una foto de sí mismo escribiendo con guantes, es el detonante de este resquebrajamiento, pues la autora expone la impostación del artista modernista al evidenciar su banalidad no celebratoria, visible en su reticencia a ensuciarse o comprometerse ideológicamente. También, le permite mostrar la dimensión laboral, desgastante y corporal de la escritura, encarnada en su propia trayectoria. Desde la cultura material tan soslayada por el ethos modernista que la vinculaba al prosaico mundo burgués, el texto produce un conocimiento revelador de la falaz superioridad ética del artista y su cómoda inserción en las lógicas mercantiles de producción serial propias de la modernidad industrial.
