No full textProblem bezpieczeństwa ekologicznego Ziemi, w tym zrównoważonej konsumpcji, od ponad sześciu dekad stanowi jeden z najważniejszych tematów debat prowadzonych przez ekonomistów, socjologów, polityków, naukowców i biznesmenów, dotyczy on bowiem przyszłości naszej planety. Celem artykułu jest określenie warunków zrównoważonej konsumpcji dla utrwalania i ulepszania prozdrowotnego stylu życia. Badania oparto na literaturze przedmiotu, a zrównoważona konsumpcja została omówiona w ramach ujęcia zawężonego do wyborów konsumenckich, nakierowanych na aspekt ekologiczny oraz związany z jakością życia, a postrzegany w kontekście żywności funkcjonalnej. Żywność funkcjonalna ma wymiar proekologiczny, służy maksymalizowaniu użyteczności konsumpcji, przy jednoczesnym zachowaniu zasobów naturalnych i poszanowaniu całego ekosystemu.The ecological safety of Earth, including the sustainable consumption, has become one of the key topics linking economists, sociologists, politicians, researchers, and businesses for the last decades. The report address focuses on the significant issue within this topic, regarding sustainable consumption for the consolidation and improvement of a healthy life. The research is based on literature analysis. The question of sustainable consumption is discussed with respect to consumer choices focused on the ecological aspects, related to life quality. The discussion focuses on functional food within this framework because just functional food has the essential pro-ecological dimension. Functional food can support the optimization of sustainable consumption regarding feeding and pro-health targets while preserving natural resources and respecting the ecosystem
Food Preservation in the Industrial Revolution Epoch: Innovative High Pressure Processing (HPP, HPT) for the 21st-Century Sustainable Society
No full textThe paper presents the ‘progressive review’ for high pressure preservation/processing (HPP) (cold pasteurization) of foods and the next-generation high-pressure and high temperature (HPHT, HPT) food sterilization technologies. It recalls the basics of HPP and HPT, showing their key features and advantages. It does not repeat detailed results regarding HPP and HPT implementations for specific foods, available in numerous excellent review papers. This report focuses on HPP and HPT-related issues that remain challenging and can hinder further progress. For HPP implementations, the reliable modeling of microorganisms’ number decay after different times of high pressure treatment or product storage is essential. This report indicates significant problems with model equations standard nonlinear fitting paradigm and introduces the distortion-sensitive routine enabling the ultimate validation. An innovative concept based on the barocaloric effect is proposed for the new generation of HPT technology. The required high temperature appears only for a strictly defined short time period controlled by the maximal pressure value. Results of the feasibility test using neopentyl glycol as the barocaloric medium are presented. Attention is also paid to feedback interactions between socioeconomic and technological issues in the ongoing Industrial Revolution epoch. It indicates economic constraints for HPP and HPT developments and emerging business possibilities. The discussion recalls the inherent feedback interactions between technological and socioeconomic innovations as the driving force for the Industrial Revolution epoch
Verhulst-type equation and the universal pattern for global population growth.
No full textThe global population [Formula: see text] (growth from 10,000 BCE to 2023) is discussed in frames of the Verhulst-type scaling, recalling the sustainable development concept. The analysis focuses on the per capita global population growth rate, for which the analytic counterpart is considered:[Formula: see text]. The focused insight reveals two near- linear domains for [Formula: see text] changes: from ~ 700 CE till ~1968 and from ~1968 till 2023. It can be considered a reference pattern for long-term global population changes. For models recalling the Verhulst-type scaling, such analysis indicates that a single pair of growth rate and system resource coefficients [Formula: see text] should describe the rise in the global population. However, the Verhulst relation with such effective parameters does not describe [Formula: see text] changes, which raises the question of whether it is adequate to describe global population changes. Notably is the new way of data preparation, based on their collections from various sources and numerical filtering to obtain a 'smooth' optimal set. The changes of [Formula: see text] were analyzed via the 'reversed protocol' analysis, in comparison to the standard pattern, namely: (i) first, the linearized, distortions-sensitive transformation of [Formula: see text] data is carried out; it indicates domains where the validated application of a given scaling equation is possible and yields optimal values of relevant parameters, (ii) the final fitting via the selected scaling equation is carried out for identified domains, and using obtained optimal values of parameters. The analysis reveals links between [Formula: see text] local 'disturbations' and some historical and prehistorical reference events, showing their global scale impacts
Global Population, Carrying Capacity, and High-Quality, High-Pressure Processed Foods in the Industrial Revolution Era
No full textThe report examines food availability and demand in the Anthropocene era, exploring the connections between global population growth and carrying capacity through an extended version of Cohen’s Condorcet concept. It recalls the super-Malthus and Verhulst-type scalings, matched with the recently introduced analytic relative growth rate. It focuses particularly on the ongoing Fifth Industrial Revolution (IR) and its interaction with the concept of a sustainable civilization. In this context, the significance of innovative food preservation technologies that can yield high-quality foods with health-promoting features, while simultaneously increasing food quantities and reducing adverse environmental impacts, is discussed. To achieve this, high-pressure preservation and processing (HPP) can play a dominant role. High-pressure ‘cold pasteurization’, related to room-temperature processing, has already achieved a global scale. Its superior features are notable and are fairly correlated with social expectations of a sustainable society and the technological tasks of the Fifth Industrial Revolution. The discussion is based on the authors’ experiences in HPP-related research and applications. The next breakthrough could be HPP-related sterilization. The innovative HPP path, supported by the colossal barocaloric effect, is presented. The mass implementation of pressure-related sterilization could lead to milestone societal, pro-health, environmental, and economic benefits
Verhulst Equation and the Universal Pattern for the Global Population Growth
Get PDFThe global population growth from 10,000 BC to 2023 is discussed within the Verhulst scaling equation and its extensions framework. The analysis focuses on per the capita global population rate coefficient Gp(P)=[dP(t)/P(t)]/dt=dlnP(t)/d, which reveals two linear domains: from 700CE till 1966 and from 1966 till 2023. Such a pattern can be considered a universal reference for reliable scaling relations describing P(t) changes. It is also the distortions-sensitive test indicating domains of their applicability and yielding optimal values of parameters. For models recalling the Verhulst equation, a single pair of growth rate and system capacity coefficients (r,s) should describe global population rise in the mentioned periods. However, the Verhulst equation with such effective parameters does not describe P(t) changes. Notable is the new way of data preparation, based on collecting data from various sources and their numerical filtering to obtain a smooth set of optimal values enabling the derivative-based analysis. The analysis reveals links between P(t) changes and some historical and pre-historical references influencing the global scale.29 pages, 3 figure
Econo- and Socio- Physics based Remarks on the Economical Growth of the World
No full textAbstract. It has been shown that the long term evolution of the Gross Product of the World after World War II can be well portrayed by the simply exponential function with the crossover at the year 1973, which coincides with the Oil Crisis onset. For such basic parameter as the S&P 500 index the single exponential behavior extends down to at least the mid of the nineteen century. It is notable that the detailed short-term insight focused on the last quarter of century revealed the emergence of the power like dependence, despite notable irregularities. However, such dependences can be introduced only when taking into account the behavior at reference-baselines years, clearly related to the society – important events in the past. The possible relationship to the growth/death evolution of microorganisms is also discussed.Keywords. Global product growth, Econophysics, Sociophysics, Microbiology.JEL.E20, F43, D24
