Revolutionising agriculture and rural economy through digital transformation: Bridging theory with practice

Revolutionising agriculture and rural economy through digital transformation: Bridging theory with practice

The role of reskilling programmes on the digital transformation at a large financial services organisation

The primary goal of this study was to examine the role of reskilling programmes on digital transformation at a Large Financial Services Organisation. The business climate and the world of work are going through an unprecedented large-scale transition - such as the transition from the agricultural economy to the industrial revolution. The era of digitisation, automation and acceleration is upon us. The society is in an economy where new critical skills have emerged and these new emerging skills have become necessary for individuals, businesses, and the economy to succeed. However, very little research has been done on the role of reskilling programmes on the digital transformation at a Large Financial Services Organisation. The study employed quantitative research and a structured closed questionnaire was used to collect field data from a selected sample of 88 respondents drawn from a target population in the study area. The field data were analysed using the Statistical Package for Social Sciences (SPSS), version 29. Statistical tools, including frequency tables, pie charts, and graphs, were used to analyse data. The study findings indicate that jobs have been significantly affected by digital transformation and new emerging job functions in large financial services organisations. A digital transformation programme had a direct relationship with the implementation of reskilling programmes. The study recommended that designing technology-focused training programmes appropriately and selecting or creating technology-focused training programmes with essential elements are necessary for successful outcomes.

Agricultural Economic Water Productivity Differences across Counties in the Colorado River Basin

This study estimates the relative contribution of different factors to the wide variation in agricultural economic water productivity (EWP) across Colorado River Basin counties. It updates EWP measures for Basin counties using more detailed, localized data for the Colorado River mainstem. Using the Schwarz Bayesian Information Criterion for variable selection, regression analysis and productivity accounting methods identified factors contributing to EWP differences. The EWP was USD 1033 (USD 2023)/acre foot (af) for Lower Basin Counties on the U.S.–Mexico Border, USD 729 (USD 2023)/af for other Lower Basin Counties, and USD 168 (USD 2023)/af for Upper Basin Counties. Adoption rates for improved irrigation technologies showed little inter-county variation and so did not have a statistically significant impact on EWP. Counties with the lowest EWP consumed 25% of the Basin’s agricultural water (>2.3 million af) to generate 3% of the Basin’s crop revenue. Low populations/remoteness and more irrigated acreage per farm were negatively associated with EWP. Warmer winter temperatures and greater July humidity were positively associated with EWP. When controlling for other factors, being on the Border increased a county’s EWP by USD 570 (2023 USD)/af. Border Counties have greater access to labor from Mexico, enabling greater production of high-value, labor-intensive specialty crops.

Consumption Pattern of A2 Milk in Bengaluru City of Karnataka of India

The dairy sector in India, often referred to as the "milk bowl of the world," is a cornerstone of the nation's agricultural economy. A2 milk, derived from native Indian cow breeds, is gaining popularity due to its perceived health benefits over conventional milk. The research aims to provide a complete understanding of factors that influence A2 milk consumption in Bengaluru, addressing both consumer behaviour and market dynamics. The study used a mixed-method approach, combining quantitative analysis through surveys and factor analysis. Data were collected from 80 respondents across Bengaluru city of Karnataka. Garrett ranking was utilised to identify key constraints faced by consumers, while the Kaiser-Meyer-Olkin (KMO) measure and Bartlett's test were applied to ensure data adequacy for factor analysis. Results indicate that 82.50% of respondents are aware that A2 milk is a good source of lactose, but awareness drops significantly for other nutritional benefits, with only 19.16% aware of its omega-3 fatty acid content. The general awareness of A2 milk's health benefits of the A2 milk is moderate, with 57.5% of respondents exhibiting a medium level of awareness. Factor analysis revealed that product quality and market considerations significantly influence purchasing decisions, while high cost and lack of awareness are major constraints. The high price is attributed to lower yield per cow and higher maintenance costs. Furthermore, 90.50% of respondents highly accepted the taste of A2 milk, indicating a strong sensory appeal. In conclusion, the study highlights the need for targeted awareness campaigns and pricing interventions to enhance consumer education and engagement. Addressing these constraints could improve market penetration and maintain consumer interest in A2 milk, promoting its health benefits, and ensuring its competitive edge in the dairy market. The findings provide valuable information for producers and marketers aiming to expand the A2 milk market in Bengaluru and similar urban areas.

Structural dynamics and sustainability in the agricultural sector: the case of the European Union

This paper seeks to draw a research agenda for unveiling the underlying bottlenecks and possibilities for improving the agricultural total factor productivity in the European Union (EU). To this aim, the paper first surveys the key challenges for the modern agricultural economy. Then, the case of the EU is discussed by looking at the convergence in the partial productivity indicators (including the GHG emission) and growth efficiency that relate to the gap in the total factor productivity growth. The results suggest that the EU member states exhibited growth inefficiency (i.e., a gap in the total factor productivity growth) of 5–9% on average during 2004–2021. The paper also discusses the possibilities to utilize the production theory for assessing the pathways towards improvements in the productivity and sustainability of the EU agriculture.

A Study of Suitable Forecasting Model for the Export Quantity of Fresh or Chilled Fish in Thailand

The aim of this study was to find a suitable forecasting model for the export quantity of fresh or chilled fish in Thailand using seven statistical methods including Box-Jenkins method, Holt’s exponential smoothing method, Brown’s exponential smoothing method, damped trend exponential smoothing method, simple seasonal exponential smoothing method, Winters’ additive exponential smoothing method, and Winters’ multiplicative exponential smoothing method. The average monthly export quantity from the website of the Office of Agricultural Economics was used for data analysis. The data set used to create the models was the export quantity from January 2011 to December 2020 for 120 months. The data set used to compare the accuracy was the export quantity from January to December 2021 for 12 months using the lowest mean absolute percentage error. The results indicated that the most accurate method was the damped trend exponential smoothing method.

Fermented aquatic weed meal (FAWM) as a protein source in Asian Catfish Clarias batrachus diets: Impacts on growth, blood chemistry profile, liver and gut morphology and economic efficiency

The global aquaculture industry is increasingly seeking sustainable alternatives to fishmeal (FM) due to its high price and shortfall in supply. In this context, fermented aquatic weed meal (FAWM) could emerge as a viable plant protein source for aquafeed. Four isoproteic diets [30 % crude protein (CP)] were formulated, incorporating 50 % total protein from FAWM comprising fermented Azolla diet (D1), Pistia diet (D2), and Eichhornia diet (D3). The control diet (D0) did not contain FAWM. At the end of the 90 days feeding trial, their growth performance, whole-body proximate composition, gut microbial load, haemato-biochemical indices, liver and gut health, and economic efficiency were determined. Fish fed with D0 had significantly (p < 0.05) improved growth performance and feed utilization compared to other treatment groups. Meanwhile, the fish supplemented with D1 diet exhibited significantly (p < 0.05) higher final weight (g), specific growth rate (%/day), weight gain (%), total biomass (g), and protein efficiency ratio among the FAWM dietary groups. The D1 group also demonstrated the significantly (p < 0.05) highest whole-body CP (64.27 ± 0.40 %) and lower crude lipid (8.24 ± 0.28 %) compared to other test diets. The total bacteria (TB) and lactic acid bacteria (LAB) in the fish gut were found to be significantly (p < 0.05) higher in D1 group. Furthermore, most of the hemato-biochemical indices of fish were significantly (p < 0.05) affected by FAWM inclusions, with few exceptions. The histological findings indicated that amongst the FAWM groups, D1 fish exhibited improved intestinal health. Nonetheless, the gut of the control fish demonstrated substantially (p < 0.05) lower villi width and crypt depth than other treatments. The D1 and D2 diet groups had significantly improved liver health. Moreover, FAWM inclusion enhanced economic efficiency by considerably reducing farm feed cost (US$/kg) and increasing return on investment (%). In summary, dietary inclusion of fermented Azolla pinnata (D1) protein at 50 % in aquafeed promoted feed utilization, growth, health, and farm economics of Asian catfish fingerlings compared to other FAWM diets.

Student Engagement in the Online Learning Environment during the COVID-19 Pandemic in Sri Lanka

Aims: This study focuses on factors affecting students’ engagement, and their issues and perceptions of online education in Agricultural Economics and Agribusiness Management related curricula in Sri Lankan state universities during the COVID-19 pandemic. Place and Duration of the Study: Data were collected from university undergraduates who studied Agricultural Economics and Agribusiness Management subjects in six state universities in Sri Lanka from January 2022 to February 2022. Methodology: The primary data were collected from 215 university undergraduates in relevant discipline through a pre-tested questionnaire developed by the researcher via Google form. All the respondents were volunteered to complete the questionnaire and submitted their responses online and those responses were collected anonymously. The Factor analysis was employed in the study to generate a single value for the dependent variable and the multiple linear regression was used to understand the factors affecting Student engagement in online learning. Results: The study indicates that the majority of students showed a positive attitude toward online education. The study findings show the student-teacher interaction is a positive and significant factor in online education in Agricultural Economics and Agribusiness Management disciplines but student-to-student interaction is not a significant factor for student engagement in online education. Moreover, when the students are female and students are in their final year, they are most likely to engage in online education. The study also shows that the majority of students prefer online education even though some highlighted the negative issues. However, providing continuous and stable access to the internet connection and providing other infrastructure facilities to students and teachers are some of the main challenges in promoting online education in Sri Lanka. In addition, proper attention should be paid to assure the quality of online education to develop students holistically. Conclusion: Study concludes that building and maintaining student-teacher interaction is one of the key determinants in student engagement in online education. Also student engagement can be enhanced through a student-centered learning activities which focus on their active contribution.

Unintended food safety impacts of agricultural circular economies, with case studies in arsenic and mycotoxins

For millennia, food systems worldwide have employed practices befitting a circular economy: recycling of agricultural and food waste or byproducts, environmentally sustainable production methods, and food preservation to reduce waste. Many modern-day agricultural practices may also contribute to a circular economy through the reuse of waste products and/or reducing agricultural inputs. There are, however, food safety impacts. This paper describes two sustainable agricultural practices that have unintended positive and negative impacts on food safety: alternative rice cultivation practices and no-till agriculture. We highlight how alternative rice cultivation practices have intended benefits of water conservation and economic savings, yet also unintended effects on food safety by reducing foodborne arsenic levels while increasing cadmium levels. No-till agriculture reduces soil erosion and repurposes crop residues, but can lead to increased foodborne mycotoxin levels. Trade-offs, future research, and policy recommendations are discussed as we explore the duality of sustainable agricultural practices and food safety.

Uncovering leveraging and hindering factors in socio-ecological interactions: Agricultural production in the Yellow River Basin as an example

Agricultural production and sustainable human livelihoods in large river basins are threatened by climate change, human activities, and resource constraints. However, due to the complexity of socio-ecological interactions and agricultural sustainability, current studies are still limited by a priori knowledge and systematic analyses, as well as by the lack of quantification and identification of key factors and valuable pathway structures for agricultural production activities. Here, we combined observation-based causal inference and network analysis to quantify and assess the complex interactions in agricultural production in the Yellow River Basin (YRB) based on data from 12 factors relevant to agriculture over 40 years. We quantitatively assessed the leveraging and hindering roles of the factors in the interacting network system and provided managers with optimization priorities and possible causal pathways to achieve sustainable agriculture in the basin. For example, the fruit yield and income of rural households were identified as leveraging factors that positively affect the agricultural economy. Groundwater was seen as a hindering factor in dampening the negative impacts of the system, highlighting the importance of preventing groundwater depletion. Moreover, the findings suggest that spatially diverse causal interaction structures exist in the YRB and have shaped a variety of distinctive agricultural development modes. Our research ideas and results highlight both systemic considerations and the amplifying or dampening role of factors in interaction pathways, providing valuable quantitative insights into the management and intervention of sustainable agriculture in large river basins. Owing to replaceable and extensible network models, the methodology has the potential to be utilized in a variety of study areas and topics with complex socio-ecological interactions.

Salt-Tolerant Plant Growth-Promoting Bacteria (ST-PGPB): An Effective Strategy for Sustainable Food Production.

Soil is the backbone of the agricultural economy of any country. Soil salinity refers to the higher concentration of soluble salts in the soil. Soil salinity is a ruinous abiotic stress that has emerged as a threatening issue for food security. High salt concentration causes an ionic imbalance that hampers water uptake, affecting photosynthesis and other metabolic processes, ultimately resulting in inferior seed germination and stunted plant growth. A wide range of strategies have been adopted to mitigate the harmful effects of salinity such as efficient irrigation techniques, soil reclamation, habitat restoration, flushing, leaching or using salt-tolerant crops, but all the methods have one or more limitations. An alternative and effective strategy is the exploitation of salt-tolerant plant growth-promoting bacteria (ST-PGPB) to mitigate salt stress and improve crop productivity. ST-PGPB can survive in salinity-tainted environments and perform their inherent plant growth-promoting and biocontrol functions effectively. Additionally, ST-PGPB can rescue plants via stress-responsive mechanisms including production of growth regulators, maintenance of osmotic balance, aminocyclopropane-1-carboxylate (ACC) deaminase activity, exopolysaccharides (EPS) activity, improvement in photosynthesis activity, synthesis of compatible solutes, antioxidant activity and regulation of salt overly sensitive (SOS) signaling pathway. Several well-known ST-PGPB, specifically Azospirillum, Bacillus, Burkholderia, Enterobacter, Pseudomonas and Pantoea, are used as bioinoculants to improve the growth of different crops. The application of ST-PGPB allows plants to cope with salt stress by boosting their defense mechanisms. This review highlights the impact of salinity stress on plant growth and the potential of ST-PGPB as a biofertilizer to improve crop productivity under salt stress.

Agricultural sector circular economy development: Agroecological approach

This study aimed to investigate the feasibility of using agroecological concepts to establish a circular economy in the agricultural industry. The paper examined circular economy as a novel economic development paradigm that seeks to optimise resource utilisation and reduce waste, particularly in the agriculture industry. The main principle of the circular economy is resource conservation, which includes the rational use of land, water and energy, as well as the preservation of biodiversity and the improvement of soil fertility. An analysis was conducted on the economic advantages of adopting a circular economy in the agriculture industry, which include the reduction of production costs, enhancement of productivity, and generation of new employment opportunities. The study also addressed the importance of digitalisation, which can significantly increase the efficiency of agricultural production using modern digital technologies for monitoring soil conditions, managing water resources and optimising processes. This paper examined the effects of the war in Ukraine on the agricultural industry, specifically highlighting a substantial decrease in the output of key crops and livestock products. A comprehensive examination of the destruction of infrastructure, soil, and water contamination exposed severe environmental issues resulting from the attacks. The successful circular concepts implemented by European countries such as the Netherlands, Sweden, Denmark, and France can be applied to the post-war revival of the Ukrainian agriculture industry. The study also addressed the experience of the Ukrainian company Kernel, which successfully implements circular practices such as recycling of production waste, use of biomass and introduction of precision farming, which reduces environmental impact and increases production efficiency. Based on the analysis, recommendations for the post-war reconstruction of Ukraine’s agricultural sector were proposed, including the identification of priority regions for recovery, stimulation of innovation and modern technologies, support for small and medium-sized farms, development of irrigation systems, environmental restoration and protection, international cooperation and support, and education and training

How increased heifer growth rate and reduced dairy cow replacement rate can improve farm economy and reduce greenhouse gas emissions - a win to win situation?

Rearing of replacement heifers makes up a significant part of the total costs in dairy farming. Nevertheless, the average age at first calving for dairy heifers still stays well above 2 years in many countries. This study examined the economic and environmental impacts of increased heifer growth rates and reduced replacement rates on Norwegian dairy farms. The current average growth rate in Norway (baseline scenario) was compared to an accelerated growth rate scenario. Within each of the two growth rate scenarios, we compared three different cow replacement rates. A farm account survey dataset containing physical and economic data on 311 Norwegian farms was clustered into three farm groups: small, medium, and large. To model economic consequences, we used the whole-farm linear programming model ScotFarm. A life cycle analysis model was used to model the environmental impacts of the baseline scenario and an accelerated growth rate scenario on the three farm groups. Accelerated heifer growth rate had a positive effect (14–28%) on farm annual gross margin depending on farm size. While accelerated growth rate resulted in only minor reductions in total emissions at farm level compared to the baseline scenario, reduced replacement rate lowered total farm level emissions by up to 8%, and emissions per unit of output by up to 6%. We conclude that an accelerated heifer growth rate scenario could potentially increase farm gross margin by some 14–28% compared with a baseline growth rate scenario. Reducing the replacement rate would be more efficient to reduce farm−level greenhouse gas emissions.

Business and Artistic Legitimacy in Antioqueña Advertising 1920–1930

In the Colombian case, in the twenties of the 20th century, businessmen made their way into a coffee agriculture economy and mining, and for this reason, in addition to ensuring the sociopolitical and economic conditions that allowed their activities, they also had to work on their legitimation before society, and to do so they turned to already recognized painters and draftsmen to carry out the advertising of their companies, adding ideological content related to modernity and progress to their products, as the brands gained their visual distinctiveness. Thanks to this contribution, the artists also legitimized their profession as publicists and designers.

Time for a change? Investigating shifts in agricultural economies and food in southern-central Norway (11th -16th c. AD)

Cattle and, to a lesser extent, sheep/goat and pigs, were crucial components of Norway’s socio-cultural and economic dynamics in the Middle Ages. Zooarchaeological analyses of faunal samples from different urban sites reveal that changes in cattle husbandry practices occurred in Norway over the medieval period, and especially in its early phases. This is clearly demonstrated in the case of medieval Oslo, where an in-depth zooarchaeological study provides the first comprehensive review of cattle husbandry strategies. In the first centuries of the medieval period (11th -mid 12th c. AD), cattle were mainly raised for milk and meat production, while fewer young and more numerous older individuals, most of which probably oxen, were present from mid 12th -13th c. AD onwards. This hypothesis is supported by biometrical analyses of cattle postcranial bones, indicating changes in the sexual composition of cattle herds over time. Therefore, from ca. mid 12th -13th c. AD onward, cattle seem to have been more used for ploughing and, only once old, to have been culled for their meat. In turn, this evidence suggests that more arable lands had to be ploughed, especially in eastern and central Norway. Here, demographic growth and settlement expansion would have led to an increase in food demand; at the same time, more favourable climatic conditions might have contributed to an increase in the availability of arable fields. This article suggests that medieval Norwegian farming was not static as historically thought, but rather connected to wider-scale agricultural innovations characterising other parts of medieval Europe.

Sustainable potato farming in Shandong Province, China: a comprehensive analysis of organic fertilizer applications

IntroductionThe potato holds the distinction of being the world’s largest non-cereal food crop and ensuring its sustainable production is imperative for global food security. Notably, China leads in both the planting area and output of potatoes globally, cementing its crucial role in the nation’s agricultural economy. A scientific assessment of the effectiveness of organic fertilizers on potato cultivation can significantly contribute to the promotion of sustainable agriculture.MethodsThis study utilizes a Propensity Score Matching (PSM) model and introduces a novel cost-efficiency approach to analyze and evaluate the production efficiency and economic impact of organic fertilizer application among 546 potato growers in Shandong.ResultsThe research findings reveal the following: Firstly, compared to the control group without organic fertilizer application, it is evident that the use of organic fertilizers enhances production technology efficiency, labor productivity, land productivity, and net profit per unit by 3.6%, 1588.47 kg/person, 16346.77 kg/ha, and 16135.32 yuan/ha, respectively. Secondly, an examination of cost efficiency among growers with different production scales indicates that those with a planting scale of 0.667-1.333 hectares demonstrate relatively high production efficiency across multiple factors. Additionally, there is an observable inverted U-shaped trend in the relationship between planting scale and production efficiency. Thirdly, the continuous application of organic fertilizers proves advantageous in mitigating inefficiencies in investment techniques, leading to cost savings and efficiency improvements in potato cultivation.DiscussionConsequently, it is recommended that the government and relevant departments enhance technical support, elevate professional training programs, and optimize the allocation of input factors. These measures aim to encourage farmers to adopt organic fertilizers, thereby promoting sustainable agricultural practices.

De- and repeasantisation through wolves: a political ecology of predator-friendly farming

While wolves are often described as 'ecological engineers', this article reframes the image of this predator as a socioecological engineer. Adopting a more-than-human political ecology perspective, I highlight the imbrication of wolf agency with the political economy of farming in co-shaping processes of agrarian change in Tuscany, Italy. A multispecies ethnography elucidates how wolves are simultaneously contributing to and undermining a modernization of sheep husbandry practices in the region. This entanglement of wolf agency in processes of de- and re-peasantization is politically relevant, affecting human-wolf relations and local levels of conflict. Through their return, wolves are necessitating shifts in farming practices and affecting the topology of agricultural landscapes, favoring either an intensification of husbandry regimes (i.e., more sheep raised indoors) or a greater competitiveness of family-led free-ranging farms with a high availability of family labor. Emphasizing this aspect is important to politicize current discussions surrounding coexistence, and supports the rise of practices that are considered to be most socially, culturally, and ecologically valuable. A focus on wolf agency in this case entails 'thinking with' wolves in co-designing alternative (co)existences, providing a more nuanced understanding of socioecological change and human-wolf relations. This article informs critical scholarship on the value of moving beyond dualist lenses while still maintaining a focus on structural processes. These are an important though not unidirectional force of change. Reframing wolves as socioecological engineers calls for further research exploring such entanglements of human and non-human agencies in the coproduction of agrarian change and human-wildlife relations.

Half a century of Japanese research on two Neglected Tropical Diseases (trypanosomiasis and leishmaniasis): Overseas scientific cooperation

Trypanosoma and Leishmania species are responsible of a range of Neglected Tropical Diseases (NTDs) from disfiguring conditions to fatal processes in humans. Both genera also affect wild and domestic animals causing diseases of public health significance and high economic impact on farm economy of developing areas. Japan has been actively involved in overseas cooperation and the country has a large scientific community. However, there is no information on the scientific output of Japanese scientists and institutions on these two NTDs. To explore the Japanese contribution and its profile, we have mined Web of Science database from 1971 to 2022 the articles by Japanese scientists, scientific areas and institutions, time-related variations of these parameters, and involvement in cooperation activities with foreign scientists. Research on Trypanosoma has been present in all the studied period, with higher production, whereas Leishmania-related activities showed a delay. A steady increased of Japanese scientific output was found up to the beginning of 2000s, whereas a certain stagnation was found in the present century. Low growth rate of research output on these two NTDs by Japanese authors in the 21st century is not correlated neither to the pattern found globally nor the situation in other parasitic infections. Thus, other elements should be considered in future analysis including the actual number of scientists involved and the available funding. Reinforcement of research groups from Japanese institutions and widening the scope of collaborations, particularly with health and academic centers from endemic regions, could trigger the Japanese productivity in the research area.

The Role of Precision Agriculture Technologies in Enhancing Sustainable Agriculture

Despite the known benefits of precision agriculture, the adoption is challenging due to the cost of investment and the farm sizes. Therefore, profitability is an important aspect to consider. This study aimed to evaluate the net returns, profitability, and investment efficiencies of PA by different economic farm sizes. The study was based on data retrieved from the Farm Accountancy Data Network (FADN) and Eurostat (year 2021). The study examined four countries (Poland, Germany, France, and Romania) under field crop farming using an investment cost of EUR 35,941–EUR 71,883 and a 20% and 15% reduction in the cost of crop protection and fertilizer usage, respectively, without compromising productivity. There is a positive relationship between the adoption of PA and farm returns for larger-scale farms. The result of the profitability and analysis of investment efficiency using Net Present Value (NPV) showed a positive value for economic farm sizes of EUR 100,000 and above. Hence, it is not economically advisable that all farmers use PA technologies with the hope that they will be profitable but with public support (subsidies) more farms will be able to use PA and be profitable. This is also an opportunity to meet the goals of the European Union Green Deal of minimizing emissions that cause climate change.
