Automation and digitalization, as long-term evolutionary processes, cause significant effects, such as the transformation of occupations and job profiles, changes to employment forms, and a more significant role for the platform economy, generating challenges for social policy. This systematic literature review aims to provide an overview of the research to date related to influences of the Industry 4.0 Revolution on human capital development and consumer behavior. A search on the Web of Science identified 160 papers that met the inclusion criteria. The major objectives aimed to identify: the main types of influences of the Industry 4.0 Revolution on human capital development and consumer behavior; the main opportunities and challenges for new directions in education associated with shifting the work environment; and the drivers for human capital development and consumer behavior through the lenses of the Industry 4.0 Revolution. The results revealed some key aspects for the development of human capital: information, new jobs, the Internet, technology, training, education, new skills, automation, communication, innovativeness, professionals, productivity, artificial intelligence, digitalization, e-recruitment, and the Internet of Things, as well as the main drivers of consumer behavior: information, e-commerce, digitalization, the Internet of Things, e-distribution, technology, digitalization, automation, personalized, performance, artificial intelligence, behavior intention, e-shopping, and data mining.

Abstract:The paper analyzes the impacts of mining activities on sustainable land management in mining areas in the Republic of Serbia and Romania and discusses the main challenges related to the management of these issues in legislation and practice. Particular attention is paid to land disturbance, mine waste management and land reclamation, as well as access to land for mining purposes, the transfer of mining royalties and the partnerships of the mining industry, governments, communities and civil society for sustainable mining. Both governments are willing to provide the adequate role to mining in strengthening the national economies, but they face numerous constraints in this matter. Sustainable mining practices and consistent implementation of the mining for the closure planning approach, within an improved legislative framework and in cooperation with stakeholders at all levels, create conditions for the development of creative, profitable, environmentally-sound and socially-responsible management and reuse of mine lands.

A two-year field trial was conducted to study the effects of biohumus, biofertiliser, and soil conditioner application on spelt grain yield in different regions (plain, hilly, and mountainous regions) in Serbia. An analysis of economic efficiency indicators of spelt production in organic farming systems was also performed. The field experiment had a randomised complete block design with three replicates in each of the three regions. One winter spelt cultivar was also studied. The largest differences in spelt yield compared to control were found in the plain region in the biohumus + biofertiliser treatment (28.0%) and the hilly region in the organic fertiliser + zeolite treatment (28.8%). The differences in grain yield between control and treatment conditions in the mountain region were insignificant. Analysis of the economic effects of organic spelt production found a significantly lower gross margin in treatments with expensive organic fertilisers (3955.05 and 1104.75 € ha–1) than the control (5094.31 and 1833.85 € ha–1), leading to the conclusion that their application was not economically justified despite the increases in grain yield. The highest production costs (3569.71 € ha–1) were observed in treatments in the hilly region, resulting in the lowest benefit-cost ratio (0.1), while the greatest benefit-cost ratio was recorded in treatments in the mountainous region (2.1). Following the economic analysis results, a significant negative correlation between the benefit-cost ratio and the total production costs (r= –0.91**) was determined and a positive correlation between the gross margin and grain yield (r=0.66*). These results lead to the conclusion that the management strategy of spelt production in organic farming systems should be harmonised with the soil and agro-ecological characteristics of the region and directed at decreasing the costs and share of external inputs. In this case, organic spelt production can be economically profitable. Highlights - Organic fertilisers and soil conditioners affect spelt grain yield. - The analysis of the economic effects of organic spelt production concluded that fertiliser application was not economically justified despite the increases in grain yield. - Treatments in the plain region displayed the best production results compared to mountain region treatments, but these did not have the best benefit-cost ratio. - Knowledge of production costs is an important element in improving the economic efficiency of organic farming systems.

Water is the source of life for all living beings, but also an irreplaceable input in agricultural production. According to the available water and land potentials in Serbia irrigation is used at generally negligible arable areas. Although it represents an agro-technical measure whose implementation usually causes significant investment costs for the farm, its application ensures high and stable yields of high quality crops' fruits, while indirectly it affects increase in incomes and continuity in farm sustainability. The main goal of the paper is presenting an assessment of the effects of investing in implementation of the irrigation system (type Tifon) on a small family farm primarily active in crop farming. Investment analysis was based on basic static and dynamic methods for assessing the effectiveness of investments. The assessment was focused to two modalities in crop production, i.e. implementation of irrigation in crop farming at 25 ha and 30 ha. In both observed modalities the investment was assessed as economically justified alternative for farm business improvement, while there are shown slightly better results with the rise of used agricultural surfaces.
