Nitrogen management and the future of food: Lessons from the management of energy and carbon

The food system dominates anthropogenic disruption of the nitrogen cycle by generating excess fixed nitrogen. Excess fixed nitrogen, in various guises, augments the greenhouse effect, diminishes stratospheric ozone, promotes smog, contaminates drinking water, acidifies rain, eutrophies bays and estuaries, and stresses ecosystems. Yet, to date, regulatory efforts to limit these disruptions largely ignore the food system. There are many parallels between food and energy. Food is to nitrogen as energy is to carbon. Nitrogen fertilizer is analogous to fossil fuel. Organic agriculture and agricultural biotechnology play roles analogous to renewable energy and nuclear power in political discourse. Nutrition research resembles energy end-use analysis. Meat is the electricity of food. As the agriculture and food system evolves to contain its impacts on the nitrogen cycle, several lessons can be extracted from energy and carbon: (i) set the goal of ecosystem stabilization; (ii) search the entire production and consumption system (grain, livestock, food distribution, and diet) for opportunities to improve efficiency; (iii) implement cap-and-trade systems for fixed nitrogen; (iv) expand research at the intersection of agriculture and ecology, and (v) focus on the food choices of the prosperous. There are important nitrogen-carbon links. The global increase in fixed nitrogen may be fertilizing the Earth, transferring significant amounts of carbon from the atmosphere to the biosphere, and mitigating global warming. A modern biofuels industry someday may produce biofuels from crop residues or dedicated energy crops, reducing the rate of fossil fuel use, while losses of nitrogen and other nutrients are minimized.

Measuring dietary intake in remote Australian Aboriginal communities

This paper reports a comparison of the practicality, acceptability and face validity of five dietary intake methods in two remote Australian Aboriginal communities: weighed dietary intake, 24‐hour recall, ‘store‐turnover’, diet history and food frequency methods. The methods used to measure individual dietary intake were poorly accepted by the communities. Quantitative data were obtained only from the first three methods. The 24‐hour recall method tended to produce higher nutrient intakes than the weighed intake method and certain foods appeared to be selectively recalled according to perceived nutritional desirability. The ‘store‐turnover’ method was most acceptable to the communities and had less potential for bias than the other methods. It was also relatively objective, non‐intrusive, rapid, easy and inexpensive. However, food distribution patterns within the communities could not be assessed by this method. Nevertheless, other similarly isolated communities may benefit by use of the ‘store‐turnover’ method.

Foodborne Yersinia : Identification and Molecular Epidemiology of Isolates from Human Infections

Yersinia enterocolitica and Yersinia pseudotuberculosis are among the major enteropathogenic bacteria causing infections in humans in many industrialized countries. In Finland, Y. pseudotuberculosis has caused 10 outbreaks among humans during 1997-2008. Some of these outbreaks have been very extensive involving over 400 cases; mainly children attending schools and day-care. Y. enterocolitica, on the contrary, has caused mainly a large number of sporadic human infections in Finland. Y. pseudotuberculosis is widespread in nature, causing infections in a variety of domestic and wild animals. Foodborne transmission of human infections has long been suspected, however, attempts to trace the pathogen have been unsuccessful before this study that epidemiologically linked Y. pseudotuberculosis to a specific food item. Furthermore, due to modern food distribution systems, foodborne outbreaks usually involve many geographically separate infection clusters difficult to identify as part of the same outbreak. Among pathogenic Y. enterocolitica, the global predominance of one genetically homogeneous type (bioserotype 4/O:3) is a challenge to the development of genetic typing methods discriminatory enough for epidemiological purposes, for example, for tracing back to the sources of infections. Furthermore, the diagnostics of Y. enterocolitica infections is hampered because clinical laboratories easily misidentify some other members of the Yersinia species (Y. enterocolitica–like species) as Y. enterocolitica. This results in misleading information on the prevalence and clinical significance of various Yersinia isolates. The aim of this study was to develop and optimize molecular typing methods to be used in epidemiological investigations of Y. enterocolitica and Y. pseudotuberculosis, particularly in active surveillance and outbreak investigations of Y. pseudotuberculosis isolates. The aim was also to develop a simplified set of phenotypic tests that could be used in routine diagnostic laboratories for the correct identification of Y. enterocolitica and Y. enterocolitica –like species. A PFGE method designed here for typing of Y. pseudotuberculosis was efficient in linking the geographically dispersed and apparently unrelated Y. pseudotuberculosis infections as parts of the same outbreak. It proved to be useful in active laboratory-based surveillance of Y. pseudotuberculosis outbreaks. Throughout the study period, information about the diversity of genotypes among outbreak and non-outbreak related strains of human origin was obtained. Also, to our knowledge, this was the first study to epidemiologically link a Y. pseudotuberculosis outbreak of human illnesses to a specific food item, iceberg lettuce. A novel epidemiological typing method based on the use of a repeated genomic region (YeO:3RS) as a probe was developed for the detection and differentiation between strains of Y. enterocolitica subspecies palearctica. This method was able to increase the discrimination in a set of 106 previously PFGE typed Finnish Y. enterocolitica bioserotype 4/O:3 strains among which two main PFGE genotypes had prevailed. The developed simplified method was a more reliable tool than the commercially available biochemical test kits for differentiation between Y. enterocolitica and Y. enterocolitica –like species. In Finland, the methods developed for Y. enterocolitica and Y. pseudotuberculosis have been used to improve the identification protocols and in subsequent outbreak investigations.

From bark bread to pizza - Food and exceptional circumstances: reactions of Finnish society to crises of food supply This study on the food supply under exceptional circumstances lies within the nutritional, historical and social sciences. The perspective and questions come under nutrition science, but are part of social decision-making. The study focuses on the first and second world wars as well as on contemporary society at the beginning of the 21st century. The main purpose of this study is to explore how Finnish society has responded to crises and what measures it has taken to sustain institutional food services and the food supply of households. The particular study interests include the school catering and food services in hospitals during the world wars. The situation in households is reflected in the counseling work carried out by state-run or civic organisations. Interest also focuses on the action of the scientific community. The decisions made in Finland are projected onto the solutions developed in some other European countries. The study is based primarily on the archive documents and annual reports prepared by food and health care authorities. Major source materials include scientific and professional publications. The evaluation of the situation in contemporary Finnish society is based on corresponding emergency plans and guidelines. The written material is supplemented by discussions with experts. Food rationing during the WWI and WWII differed in extent, details and unity. The food intake of some population groups was occasionally inadequate both in quantity, quality and safety. The counseling of the public focused on promoting self-sufficiency, improving cooking skills and widening food habits. One of the most vulnerable groups in regard to nutrition was long-term patients in institutions. As for future development, the world wars were never-theless important periods for public food services and counseling practices. WWII was also an important period for product development in the food industry. Significant work on food substitutes was carried out by Professor Carl Tigerstedt during WWI. The research of Professors A. I. Virtanen and Paavo Simola during WWII focused on vitamins. Crises threatening societies now differ from those faced a hundred years ago. Finland is bet-ter prepared, but in many ways more vulnerable to and dependent on other actors. Food rationing is a severe means of handling the scarcity of food, which is why contemporary society relies primarily on preparedness planning. Civic organisations played a key role during the world wars, and establishing an emergency food supply remains on their agenda. Although the objective of protecting the population remains the same for nutrition, food production, and food consumption, threat scenarios and the knowledge and skill levels of citizens are constantly changing. Continuous monitoring and evaluation is therefore needed.

Aplicando netnografía a la obtención del mapa de posicionamiento para empresas de distribución alimentaria

[ES] Las comunidades online se han convertido en un lugar de encuentro muy popular para los consumidores que les permite compartir información. En este artículo se presenta una técnica de información novedosa como la netnografía, y se aplica para determinar cuál es el posicionamiento de las empresas de distribución alimentaria. Tras la recogida y análisis de 506 mensajes válidos de la comunidad online Ciao, se pudo conocer qué atributos se asociaban a seis establecimientos de alimentación analizados. Mercadona se asocia con la calidad de su marca de distribuidor y una escasa variedad de marcas/productos. Las tiendas discount, Lidl y DIA, destacan por la posibilidad de mejora en la limpieza del establecimiento y la localización de los productos. Los hipermercados, Eroski, Alcampo y Carrefour, son destacados por su variedad de marcas/productos, y alejado del domicilio. También se ha identificado a los competidores más directos de cada empresa, encontrándose una competencia entre los formatos de venta del mismo tipo (intratipo). El uso de la netnografia, técnica relativamente reciente, supone la mayor originalidad del trabajo. Además, las conclusiones obtenidas, que son coincidentes con estudios anteriores, muestran que la netnografía puede ser una fuente de información para determinar cuál es la imagen comercial y el posicionamiento de las empresas.

Developmental and ecological stages in the life history of milkfish Chanos chanos Forsskal

Seven stages in the life history of the milkfish C. chanos , are recognized and suggested: A, embryonic; B, yolksac larval; C, larval; D, postlarval; E, juvenile; F, subadult; G. adult. An outline is presented of the life history. It is concluded that the milkfish, throughout the known stages of their life history are well adapted and equipped for optimal survival. High swimming performance, broad flexibility in feeding habits, high adaptability to a wide range of physicochemical conditions of the environment are but a few of the adaptations. The main driving force in all developmental stages is the evolutionary response to food distribution and availability followed by predation pressure.

The nutritional status of fishing and non-fishing communities of Lake Victoria basin

An individual-based model of the early life history of mackerel (Scomber scombrus) in the eastern North Atlantic, simulating transport, growth and mortality

The main purpose of this paper is to provide the core description of the modelling exercise within the Shelf Edge Advection Mortality And Recruitment (SEAMAR) programme. An individual-based model (IBM) was developed for the prediction of year-to-year survival of the early life-history stages of mackerel (Scomber scombrus) in the eastern North Atlantic. The IBM is one of two components of the model system. The first component is a circulation model to provide physical input data for the IBM. The circulation model is a geographical variant of the HAMburg Shelf Ocean Model (HAMSOM). The second component is the IBM, which is an i-space configuration model in which large numbers of individuals are followed as discrete entities to simulate the transport, growth and mortality of mackerel eggs, larvae and post-larvae. Larval and post-larval growth is modelled as a function of length, temperature and food distribution; mortality is modelled as a function of length and absolute growth rate. Each particle is considered as a super-individual representing 10 super(6) eggs at the outset of the simulation, and then declining according to the mortality function. Simulations were carried out for the years 1998-2000. Results showed concentrations of particles at Porcupine Bank and the adjacent Irish shelf, along the Celtic Sea shelf-edge, and in the southern Bay of Biscay. High survival was observed only at Porcupine and the adjacent shelf areas, and, more patchily, around the coastal margin of Biscay. The low survival along the shelf-edge of the Celtic Sea was due to the consistently low estimates of food availability in that area.

Pelham Cares Inc. fonds, 1980-2015

The beginnings of Pelham Cares occurred in 1982 when the Mayor of Pelham, Eric Bergenstein, received a letter from Janet Hassall, a social worker with Niagara Regional Home Care. Hassall requested that a Social Service Committee be established in Pelham to address gaps in community services, a practice that several other communities in the Region had adopted. Such committees were commonly composed of church parishioners, so Bergenstein contacted Canon J. Nowe of the Holy Trinity Anglican Church, who expressed an interest in participating in such a committee. Bergenstein arranged a meeting in June, 1982 at the United Church Hall in Fonthill, for any interested parties to learn more about the existing Social Service Committees in the Region. The meeting was not part of a Town Council project, but rather an initiative undertaken by Mayor Bergenstein in a personal capacity. Subsequent meetings chaired by Eric Bergenstein were held throughout the remainder of that year, during which the name of Pelham Cares was decided, a steering committee established, and services to be offered were determined. These initially included “visits with the lonely, the shut-ins, at home, hospital or on an outing ; run errands for those who are “stuck”; step in, in emergencies, or regularly, to free a parent or spouse who can’t otherwise get a “break”; in emergencies, provide food, clothing, furniture, medicine and other necessities”. The first official meeting of Pelham Cares occurred in January 1983. Currently, the main services offered by Pelham Cares are a food bank; transportation services to medical appointments; and sponsorship programs to allow youth with limited financial means to participate in sports, recreational and educational activities. The organization also provides emergency food, supplies or short term accommodation due to fire or other catastrophic loss, as well as providing referrals to appropriate organizations or agencies. Pelham Cares is dependent on the funding from community partners such as service clubs, citizens, local businesses, financial institutions and churches. These services are provided by volunteers and one part-time employee. A permanent location for Pelham Cares was established in 2014 with the purchase of a property on Highway 20 East in Fonthill, after a 30 years search for a permanent facility.

Cadeia produtiva da farinha de mandioca na perspectiva da análise de filière e supply chain management :um estudo de caso das relações entre a agroindústria e a distribuição

This research aims to study the manioc flour productive chain in order to understand how the relationship between its segments happens, specially between the flour agroindustry and the distribuition. This research was made from a study of case that envolved three agro industries from the Potiguar wasteland and a company of food distribution. The filiére and the supply chain management analysis were applied to identify the functioning and the organization of the manioc flour productive chain. From the study of case it s noticed that the existing contracts, even the informal ones, has mutual benefits and it suggests that they be legalized
