The Internet of Things (IoT) is a computing concept that describes the idea of everyday physical objects being connected to the Internet and being able to identify themselves to other devices, and day by day it becomes popular in everyday life as well as in entrepreneurship. The IoT covers broad areas, including manufacturing, the health sector, agriculture, smart cities, security and emergencies among many others. The market for the industrial IoT is estimated to surpass 107 billion euros by 2021 and reach a compound annual growth rate of 7.3% as of 2020. The IoT makes an impact on all industries and provides benefits for various areas of business; however, business may be faced with some risks as well. The research aim is to analyse the benefits and risks of the IoT in entrepreneurship. The descriptive method, analysis and synthesis, the induction and deduction methods were used to achieve the aim. The research has revealed that the IoT can provide several opportunities for business in all fields of operations – marketing, logistics, accounting and human resource management. However, businesses may be faced with some challenges related to privacy and security, processing, analysis and management of data, as well as monitoring and sensing.

Social enterprises have positive effect on sustainable development, and they have become an important instrument for solving social problems (especially in rural areas), as the national and local governments alone cannot solve all such problems. To foster the development of social entrepreneurship, Latvia has introduced several support instruments for social enterprises, which include tax relief, privileged procurement contracts, grants, as well as non-monetary kinds of support. However, social entrepreneurs often point out that support from the national and local governments is insufficient, while the support instruments stipulated in the Social Enterprise Law are not widely used. Therefore, the aim of the research is to analyse national and local government support instruments for social enterprises in Latvia. The research found that the most important financial instrument fostering the development of social entrepreneurship in Latvia is a grant scheme administered by the Ministry of Welfare and the JSC Development Finance Institution Altum, which is available in the range of EUR 5000 to 200 000 for investment and working capital. In the period 2017‒2020, 94 social entrepreneurship projects with a total budget of EUR 6 million were supported, which could be viewed as significant financial support. In contrast, immovable property tax relief, exemption from enterprise income tax (on profits) and relief from this tax for several categories of non-business expenses are considered by social entrepreneurs to be an insignificant kind of support. There is also lack of experience and practice regarding the inclusion of social criteria in public procurement in Latvia.

The article states that in the conditions of climate crisis aggravation the decarbonisation of the economy acquires the status of a global initiative aimed at achieving zero CO2 emissions by 2050. It is emphasised that this initiative is closely accompanied by legislation, business modernisation programmes and the creation of equal conditions for both domestic producers and exporters of carbon-intensive products (in particular, through the introduction of the carbon border adjustment mechanism – CBAM) and new rules of the world market. The consequences of CBAM implementation into Ukrainian metallurgical enterprises and the development of their foreign economic activity are determined in the example of Metinvest Group (Ukraine) enterprises. The ambivalence of CBAM is proven. It is substantiated that CBAM implementation will not accelerate, but, on the contrary, will slow down the process of decarbonisation, which will eventually lead to the loss of domestic metallurgical enterprises’ competitive position in the European market of metal products. Regarding the need to take transitional measures to decarbonise the metallurgical business (first of all, to ensure proper investment), the decision should be based on the expected decoupling effect – positive dynamics of economic growth while reducing the negative impact on the environment. The estimating method of the decoupling effect has been modified according to the integrated approach. A trend analysis of the integrated decalin effect indicator and its components was performed in Metinvest Group companies (Ukraine). Based on the results of econometric analysis of the impact of investment on greenhouse gas emissions, the author’s model for determining the volume of investment in the process of decarbonisation of metallurgical enterprises for the period up to 2050 is proposed. Comparative analysis is performed regarding investment in the process of decarbonisation under the scenarios by GMK Center, IEA, McKinsey and Roland Berger, as well as the author’s model.

This study aimed to identify the most characteristic trends in the area of fodder production and the use of fodder as factors in the development of animal husbandry in Ukraine under conditions of war as the modern challenge for these industries. Russian military aggression is a powerful challenge for the economy of Ukraine, including its fodder production, as well as other countries of the world, reflecting on the aggravation of global problems of food shortages and food security. The effect of the mentioned challenge in Ukraine is superimposed on the identified negative trends and situation, which were formed before the beginning of 2022. Calculations based on them show that the occupation of large areas of Ukraine by Russian aggressors and hostilities caused a significant decrease in the production of livestock products due to a 13–17% decrease in the number of animals. Accordingly, consumption of fodder at the expense of these regions decreased by 16%. However, the situation is very dynamic as the war continues. Given the limitations of state support for the industry, until the end of the war the main efforts to improve fodder production in Ukraine should objectively be related to the maximum optimization of the structure of fodder rations by increasing the share of less energy-intensive forages. Every challenge creates new opportunities, therefore the post-war development of fodder production and use in Ukraine will become highly innovative.

Unemployment is a major issue in Nigeria because the youth finds it difficult or impossible to secure jobs that meet their expectations. There appears to be a mismatch between graduate skills and those sought by employers. The study investigated the effect of International Institute of Tropical Agriculture (IITA) youth Agripreneurs (IYA) programme on employment and income generation on cattle fattening enterprise under the N2Africa Borno youth project. A two-stage sampling procedure was used to select IYA participants and non-participants. Results revealed that the majority of respondents were males in both categories. It also indicated that youths who are in their productive age are more into cattle fattening enterprise in both categories. The study also found that, unemployment and skill acquisition are the main driving reasons for participating in IYA. It also indicated that both categories of respondents’ required external capital support for start-up of their enterprise, and that IYA programme participants on the average earn more income per month than nonparticipants. IYA programme participants generated more employment opportunities which implied that the programme had not only empowered participants but also made the participants’ become employers. The study recommended that there is a need to support youths with funds, access to trainings on capacity development and skill acquisition to make them self-employed and job creators.
