Desafios alimentares, mudanças tecnológicas e geopolítica alimentar

Abstract In recent years, food insecurity has worsened despite decades of progress. Agrifood systems must evolve to address population expansion and climate change simultaneously. A problem of this magnitude necessitates the development of technologies that simultaneously increase (nutritious) food production and protect the environment. Based on an a diagram analysis of the economic model of technological change, this article explores various technological paths that can emerge in response to rising food prices and the need to preserve land. This article indicates, through the use of specialized literature, that the hypotheses derived from the analysis of the technological change model already exist. In addition, we investigate the potential geopolitical effects of these technological shifts on the global agri-food industry. Changes aimed at conserving land must encourage urban food production, systematic resource optimization on abundant high-quality land, and regenerative practices. In addition to rising food prices and population growth, the increasing significance of urban consumers and the internalization of environmental values should drive these various developments.

Research on technology innovation path of Intelligent Manufacturing enterprises-Based on qualitative comparative analysis of fuzzy sets under TOE framework.

Intelligent manufacturing enterprises play a crucial role in the modern industrial system and are key to high-quality economic development. However, most current research on intelligent manufacturing technology innovation focuses on single variables, lacking a comprehensive analysis from a linkage grouping perspective. This paper constructs an analytical framework for the technology innovation path of intelligent manufacturing enterprises from three dimensions: technology level, organization level, and environment level. Six antecedent variables are selected: R&D investment, digital transformation, human capital structure, profitability, government support, and competitive position. Using the fuzzy sets of qualitative comparative analysis (fsQCA) methodology, the paper examines the technological innovation paths of intelligent manufacturing enterprises in China. The research indicates that no single antecedent variable is necessary for high technological innovation; instead, the innovation path results from the synergistic effect of multiple conditions. The study identifies three paths leading to high technological innovation in intelligent manufacturing:"Government and Human Resource driven types," "Environmental-Organizational linkage types,"and"Organizational Resilience dominant types." This analysis provides reference suggestions for enterprises to adopt suitable development strategies based on their competitive positions.

Identification of Hydrogen-Energy-Related Emerging Technologies Based on Text Mining

As a versatile energy carrier, hydrogen possesses tremendous potential to reduce greenhouse emissions and promote energy transition. Global interest in producing hydrogen from renewable energy sources and transporting, storing, and utilizing hydrogen is rising rapidly. However, the high costs of producing clean hydrogen and the uncertain application scenarios for hydrogen energy result in its relatively limited utilization worldwide. It is necessary to find new promising technological paths to drive the development of hydrogen energy. As part of technological innovation, emerging technologies have vital features such as prominent impact, novelty, relatively fast growth, etc. Identifying emerging hydrogen-energy-related technologies is important for discovering innovation opportunities during the energy transition. Existing research lacks analysis of the characteristics of emerging technologies. Thus, this paper proposes a method combining the latent Dirichlet allocation topic model and hydrogen-energy expert group decision-making. This is used to identify emerging hydrogen-related technology regarding two features of emerging technologies, novelty and prominent impact. After data processing, topic modeling, and analysis, the patent dataset was divided into twenty topics. Six emerging topics possess novelty and prominent impact among twenty topics. The results show that the current hotspots aim to promote the application of hydrogen energy by improving the performance of production catalysts, overcoming the wide power fluctuations and large-scale instability of renewable energy power generation, and developing advanced hydrogen safety technologies. This method efficiently identifies emerging technologies from patents and studies their development trends. It fills a gap in the research on emerging technologies in hydrogen-related energy. Research achievements could support the selection of technology pathways during the low-carbon energy transition.

Projecting future carbon emissions from cement production in developing countries

Achieving low-carbon development of the cement industry in the developing countries is fundamental to global emissions abatement, considering the local construction industry’s rapid growth. However, there is currently a lack of systematic and accurate accounting and projection of cement emissions in developing countries, which are characterized with lower basic economic country condition. Here, we provide bottom-up quantifications of emissions from global cement production and reveal a regional shift in the main contributors to global cement CO2 emissions. The study further explores cement emissions over 2020-2050 that correspond to different housing and infrastructure conditions and emissions mitigation options for all developing countries except China. We find that cement emissions in developing countries except China will reach 1.4-3.8 Gt in 2050 (depending on different industrialization trajectories), compared to their annual emissions of 0.7 Gt in 2018. The optimal combination of low-carbon measures could contribute to reducing annual emissions by around 65% in 2050 and cumulative emissions by around 48% over 2020-2050. The efficient technological paths towards a low carbon future of cement industry vary among the countries and infrastructure scenarios. Our results are essential to understanding future emissions patterns of the cement industry in the developing countries and can inform policies in the cement sector that contribute to meeting the climate targets set out in the Paris Agreement.

However, echelon utilization is still in its early stages. In order to grasp the current development status of echelon utilization technology and to further solve the existing technological bottlenecks, this article analyzes the its process and current technological development status, and puts forward targeted suggestions.

Technological intensity and local socio‐economic development

AbstractThis study aimed to empirically analyse the relationship between technological intensity profile and local socio‐economic development, using the theories of path dependence and microregional agglomeration economies. We applied the technique of linear hierarchical modelling with data from 645 municipalities in Brazil. Our results demonstrated that current municipal socio‐economic development could be explained by the local technological path itself but even more so by the technological intensity of the microregion. This article's contribution lies in its union of two theoretical perspectives and its adoption of a quantitative approach, allowing for the analysis of municipal development at two levels, local and microregional.

Taking the carbon capture and storage, wind power, PV or other renewable technology path to fight climate change? Exploring the acceptance of climate change mitigation technologies – A Danish national representative study

Despite numerous prior studies regarding public acceptance of climate change mitigation technologies, most academic papers focus on individual technologies in their analyses. Little is known about the acceptance of multiple low-carbon energy technologies. This study bridges this research gap and explores the cross-technology acceptance of various energy solutions at different locations. Thus, we provide a comprehensive understanding of public acceptance patterns by analysing a broader range of technologies concurrently, focusing on: (a) nuclear power, (b) district heating, (c) energy-saving technologies, (d) onshore, nearshore, and offshore wind power (WP), (e) photovoltaics (PV) installed on agricultural land, industrial roofs, and private roofs, and (f) carbon capture and storage (CCS) in offshore, nearshore, rural onshore, and urban onshore locations. Based on Danish nationally representative survey data, our results give strong policy indications that PV on industrial rooftops is accepted at the highest level. In contrast, nuclear power, onshore rural and urban CCS, and nearshore CCS are the least accepted technologies to combat climate change among the Danish public. Additionally, we discover that the acceptance of a specific technology is contingent on locations. Specifically, the public acceptance of PV, WP, and CCS depends on the place of living and the potential location of technology placement. Finally, this study explores subgroup analyses to compare acceptance differences according to gender, age, education, income, and location of residence.

Energy trading model for multi-microgrid energy storage alliance based on Nash negotiation

With the continuous development of the electricity market and the gradual expansion of the number and scale of participation in market transactions, the traditional energy trading model has limited the formation of a competitive pattern of multi-agents. In this paper, a new multi-microgrid energy storage alliance energy trading model based on Nash negotiation is proposed. This model takes energy storage, multi-microgrid, and superior power grid enterprises as the main participants and establishes an energy market trading model with “buy–sell” cooperation and competition coexisting within the alliance based on Nash negotiation theory. Through the interaction of electricity between different entities, energy conversion and complementary utilization are increased, achieving reasonable allocation of resources, enhancing the overall flexibility of the alliance, and promoting the local consumption of a high proportion of new energy. The simulation results of the example show that the energy trading model based on Nash negotiation can fully leverage the initiative of demand-side participation in scheduling and improve the utilization rate of energy storage systems while ensuring the payment benefits of all participating entities, which can provide technical support for energy complementarity among multiple entities and provide new technological paths for the sustainable development of energy sharing mechanisms.

Study on the impact of industrial digitization on carbon emissions: evidence from China’s Logistics Industry

Digitization of the industrial sector is critical to combat climate change and reduce carbon emissions. The application of digital technology in traditional high-carbon emission industries can improve energy use efficiency and provide an essential technological path for carbon reduction. This study uses a coupled coordination degree model to measure the degree of integration between China’s logistics industry and the digital economy. An environmental Kurtzwarts curve (EKC) panel and a non-linear mediation model was then constructed to analyse the impact of digitization of China’s logistics industry on carbon emissions and its driving mechanisms using panel data from 30 regions in China from 2011 to 2020. The empirical results show that: (1) The level of integration between the logistics industry and digital economy led to an evident characteristic of ‘high in the east and low in the west.’ However, the regional differences are gradually decreasing over time. (2) The influence of the integration between the logistics industry and digital economy on carbon emission is in an inverted U-shape when the integration degree of the two exceeds the inflection point value of 0.76 to play the role of carbon At present, only in Guangdong, the degree of integration crosses the inflection point and plays an environment-friendly digital role. (3) As a crucial external environmental condition affecting carbon emissions, the degree of integration between logistics and digital economy will play an early role in carbon emission reduction under environmental regulation. (4) The degree of integration of the logistics industry and digital economy achieves carbon emission reduction through strengthening energy use efficiency and technological progress, in which the mediating effect of energy consumption intensity accounts for 23.05% of the total effect, ranging from 18.82% to 31.68%; the mediating effect of technological progress accounts for 13.25% of the total effect, ranging from 12.67% to 14.40%.

Technological search strategy and breakthrough innovation: An integrated approach based on main-path analysis

The significance of breakthrough innovations is not only reflected in their technological novelty but also in their impacts on the evolution of industrial technology paths. In the context of accelerating digitalization and industrial upgrading, it is particularly important to investigate how can firms manage their technological search strategies to generate breakthrough outputs. We develop a main-path-based approach to complement the existing method of breakthrough innovations in terms of their impact on industrial technology evolution. Besides, based on a sample of 29,620 USPTO patents of the electric communication industry, for the period 1976–2021, we further link firms' technological search strategies of local and distant modes to their breakthrough innovation and find that the two search modes have respective and joint effects on firms' breakthrough performance concerning both technological novelty and industrial impact. This paper not only provides a more integrated approach to identifying breakthrough innovations but also explores the impact of a firm's technological search strategy on them.

High stability and low noise laser-diode end-pumped Nd: YAG ceramic passively Q-switched laser at 1123 nm based on a Ti3C2T x -PVA saturable absorber

We report a high repetition frequency, high power stability and low laser noise laser-diode (LD) end-pumped Nd: YAG ceramic passively Q-switched laser at 1123 nm based on a Ti3C2T x -polyvinyl alcohol (PVA) film as a saturable absorber (SA). A Brewster polarizer (BP) and a birefringent crystal (BC) are incorporated to enable frequency selection and filtering for the passively Q-switched 1123 nm pulsed laser to improve the power stability and reduce the noise. When the pump power is 5.1 W, an average output power of 457.9 mW is obtained, corresponding to a repetition frequency of 1.09 MHz, a pulse width of 56 ns, a spectral line width of 0.65 nm, a power instability of ±0.92%, and a laser noise of 0.89%. The successful implementation of the “Ti3C2T x -PVA film passively Q-switching” combined with “frequency selection and filtering of BP + BC” technology path provides a valuable reference for developing pulsed laser with high repetition frequency, high stability and low noise.

Research on the Impact of Digital Economy on Residents' Consumption Upgrading

The deep integration of digital technology and the real economy has injected new power into the consumer market, and the role of digital economy in promoting residents' consumption upgrading is especially obvious in the post epidemic era. Panel data from 2014-2020 of 30 provinces in China except Tibet are selected to examine the driving role of digital economy on residents' consumption upgrading based on the perspective of technological innovation intermediary. The results of the study show that: from the overall level, the digital economy significantly promotes the upgrading of residents' consumption, but there is obvious regional heterogeneity; from the perspective of the mediation effect, the digital economy promotes the optimization of the residents' consumption structure through the channel of technological innovation; however, the technological innovation path of the digital economy to promote the level of residents' consumption is not significant, due to the impact of the two types of technological innovation, namely, product innovation and technological innovation, which are offsetting the impact of the two types of technological innovation on the level of residents' consumption. significant. Therefore, we should accelerate the breakthrough of digital technology innovation, fill the gap of digital economy development between regions, promote the coordinated development of East, Middle East and West China, and promote the upgrading of residents' consumption.
