The necessity to increase genetic diversity in agriculture has been widely discussed during the last decades. Heterogeneous populations are one of the ways to increase genetic diversity in varieties of self-pollinating cereals. The aim of this research was to compare grain yield, its stability, foliar diseases severity and competitiveness against the weeds of spring barley (Hordeum vulgare) populations and homogenous varieties. Field trials consisting of three types of populations (simple, complex and composite cross populations – CCP) containing different levels of diversity and three check varieties were carried out during 2015−2018 under organic and conventional farming systems. No one of the populations had a significantly higher average yield than any of the check varieties. CCP1 showed a tendency to be more productive under organic growing conditions and can be characterized as widely adaptable to various growing conditions with a significantly higher yield as the average overall environments. One of the complex populations showed adaptability to favourable growing conditions and yield insignificantly higher than overall average. Other studied populations can be characterized with wide adaptability and various yield levels. For most of the populations under organic and conventional conditions, a significantly lower net blotch (caused by Pyrenophora teres) severity was observed in comparison with the most susceptible variety; infection with powdery mildew (caused by Blumeria graminis) lower than for check varieties was observed under organic growing conditions, whereas such trend was not observed under conventional conditions. All populations had a significantly lower crop ground cover and slightly lower competiveness against weeds than the variety with the best competitiveness

Grain legumes are important crops for the diversification of European farming system. In Latvia, the areas of faba beans (Vicia faba) and field peas (Pisum sativum) are increasing and legumes that have not been previously cultivated are sown. Globally, the important causal agent of legume diseases belongs to the genus Botrytis. Botrytis spp. cause significant losses in faba beans and infect a wide range of legume crops. Currently, the composition, pathogenicity and biological characteristics of Botrytis species in legumes in Latvia are not known. The aim of this study was to summarize the information about Botrytis spp. on legumes, using monographic method. The researches carried out all over the world show a high genetical diversity of Botrytis cinerea. Non-host specific B. cinerea has been found on 586 plant genera, including many legume crops. B. cinerea causes gray mold on leaves and pods of field peas, gray mold on pods of faba beans, and chocolate spot of faba bean leaves. B. fabae can infect plants from Fabaceae family. B. fabiopsis is known as a pathogen of faba beans. B. fabiopsis has been observed in Latvia, but no information is available on its presence in Europe. B. pseudocinerea has been found on beans, peas, and clover (Trifolium). Some other Botrytis spp. have been detected on legumes; however, their occurrence and importance are not clear. Summary of existing knowledge about Botrytis spp. on legumes is necessary to continue investigations about the diversity and economic importance of Botrytis spp. in legumes.

Brown rust caused by Puccinia recondita is a significant disease in cereal growing areas worldwide. On average, brown rust can cause yield losses from 10% to 40% resulting in economic losses. The disease damages the leaves, stems and glumes of cereals. Classification of the pathogen causing brown rust has undergone several revisions. There are two different opinions about the causal agent causing brown rust on rye and wheat. Some scientists consider that the causal agent of brown rust in wheat (Triticum aestivum L.) and rye (Secale cereale) is included in the broad species of P. recondita defined by Cummins, but other scientists consider that there are two species causing brown rust – P. recondita in rye and P. triticina in wheat. There are many studies about the races of P. recondita in wheat: in North America, 70 races are collected every year; in Canada, 35 races have been found; in Europe, 105 races have been found. Unfortunately, there are no studies about the races of the pathogen of rye. P. recondita is a heteroecious fungus with a complicated life cycle. For successful development, the fungus requires cereals as primary hosts and different alternative hosts, depending on the specialization of the pathogen. Specific studies about the biology, distribution and harmfulness of Puccinia recondita in Latvia are necessary. Monographic method was used for this study. The aim of this article is to summarize the information from the literature about Puccinia recondita, the causal agent of brown rust, with emphasis on the occurrence, harmfulness, taxonomy, and life cycle of P. recondita f. sp. secalis.

The concepts of bioeconomy development require the integration of different sectors and economic activities. Bioeconomy helps to achieve the goals of sustainable development. This paper provides an overview of the cooperation for the need of bioeconomy development, examining it from agricultural cooperatives development, theoretical concept and European countries policy and Kazakhstan perspective. The research methods are induction and deduction, monographic, the group interview, statistical data analysis and synthesis, descriptive, matching and comparison and other methods. The cooperation passes through several levels of development – information, consultation, joint action, collective decision-making. The cooperation within farmers (horizontal cooperation) is so far narrow and limited to traditional cooperatives that bring together producers of the same product. New forms of cooperation and more diverse directions in national, regional and local levels are needed to develop the bioeconomy. Partnerships, the interdepartmental and interdisciplinary cooperation based on knowledge and innovation should be established between farmers, agri-food companies and scientific institutions, Kazakhstan and other countries universities. The agricultural and rural development advisory system should be improved, and new measures to promote communication, counselling and cooperation should be introduced.

Catch crops contribute to soil and environmental quality, which has determined a growing interest in their use as a nature-based solution. Though, the introduction of catch crops increases the complexity of farm management and is related with additional costs. In Latvia, the area under catch crops accounts for less than 5% of the arable land, while 30% is bare over the winter. In order to identify the possibilities for promoting of catch crops in Latvia, the objective of the study is to explore the support practices for growing of catch crops in the Baltic Sea region countries. The paper seeks to explore the main benefits associated with the growing of catch crops, followed by the study and synthesis of the main support measures. For the study, numerous information sources have been explored and appropriate research methods applied. Catch crops reduce nutrient leaching from the soil, transfer nutrients to the next crop, improve soil quality, reduce soil erosion, and mitigate climate change; these benefits can translate also at farm level, mainly as reduced N inputs. Growing of catch crops is being increasingly supported in the Baltic Sea countries – as a greening measure and by different agri-environment and climate measures of the RDPs 2014−2020. Growing of economic focus area catch crops (supported in quite a similar approach in these countries) and introduction of agri-environment scheme for catch crops (supported in directly and/or indirectly targeted way) can contribute to the solving of environmental problems and decrease the share of bare land left over the winter in Latvia.

The article deals with the issue of rural population decline in Poland in 1995−2017. The aim of the study was to present the phenomenon of depopulation involving a decrease in the number of people living in rural areas in Poland at the local level. Based on the literature, the potential effects of depopulation on local development were indicated. The data of the Central Statistical Office and the results of own research carried out in three rural communes in 2019 were used. The occurrence of regional differentiation of rural depopulation processes in Poland was found. Analysing the phenomenon at the local level, it was found that as much as 38.6% of rural communes were characterized by depopulation (a loss of over 5% of the population), including for 10.7% of communes, the population decline in the analysed period was more than 15%. These areas can be considered as problem areas. A particularly unfavourable situation occurs in eastern Poland and the Opolskie Voivodeship. There was a positive correlation between the loss of population and the development of own revenues of communes’ budgets. Studies show that the phenomenon of depopulation is mainly caused by a negative natural increase, which was preceded by a migration outflow associated with the lack of jobs in rural areas.

Baltic States and Finland are vibrant regions with similar sized population and historical experience. Their adaptation to the new digital era is undermined by lack of professionals. Across the EU a major reason for labour shortage in science, technology, engineering and mathematics (STEM) fields professionals lies in the insufficient supply of higher education graduates due to stagnant enrolment rates in STEM fields. The aim of this research addresses the existing trends in tertiary STEM education in Finland, Estonia, Latvia and Lithuania. This includes the tasks of analysing the quantitative trends (enrolment and graduation) in the HEIs of Baltics and Finland over the period from 2013 to 2017 as well as analysing the structural changes taking place in the respective higher education systems from 2013 to 2018. The Baltic States combined have numerical advantages in terms of young people, and young professionals (25−34 year olds) with tertiary education. However, in terms of the number of students and graduates Finland is at the forefront. The largest proportion of students enrolling in STEM fields lie within Finland (33.9%) whereas the smallest one is in Latvia (24.0%). Finland is also a leader in the share and total number of information and communication technology (ICT) graduates. In the period 2013−2017 Latvia’s results improved in two (5th and 6th) of the STEM study fields, Lithuania made a remarkable result in one STEM (6th) field by 46.9%, Estonia saw a relative increase in the 5th and 6th study field while Finland experienced a numerical decrease in all three STEM fields.

The aim of this paper is to summarise the experience gained at different levels of tourism destination planning in Latvia, identify the problems encountered during strategy planning and implementation, analyse the causes, and search for solutions. Theoretical aspects of the tourist destination planning have been extensively reviewed in publications, yet the research on what main problems planners have faced during the planning process, has been insufficient. In the last twenty years of Latvian tourist destination planning, at different levels, part of the plans were developed as documents; however, not all of them were implemented. The qualitative research summarises the experience of municipalities and tourism destination planning in Latvia. The research results show formally drafted tourism development documents of different levels and types in Latvia conform to modern planning theory and practice. In some cases even the latest knowledge and experience; create unique, innovative and competitive solutions. Tourism planning at the local level is often a painful process which raises a number of unresolved issues and unimplemented activities. The most significant differences observed from a comparison of theory and good planning practices in tourism development planning in Latvia are that the planning process is implemented within the boundaries of one municipality without taking into account the larger boundaries of tourist destinations. The involvement of entrepreneurs has only been formal and major, large-scale investment projects have not been planned or implemented.

Tourism development contributes to the vitality of rural areas: it increases employment opportunities for residents, promotes the development of relations among different business entities and attractiveness of rural environment. In this article, the situation regarding the development of one type of tourism – educational tourism – in Lithuanian rural areas, factors encouraging and limiting this development have been analysed. The research question is what are the main problems regarding the development of educational tourism in rural areas. The aim of the research is to present relevant solutions after the analysis of the problems regarding the development of educational tourism in rural areas. Theoretical research was performed while applying methods of content analysis and synthesis of scientific literature and other researches. The method of case analysis was chosen to describe the state of the development of educational tourism and to identify main problems. In total 18 cases were analysed (18 providers of the educational tourism services in rural areas). In order to collect necessary information, methods of semi-structured interview, analysis of secondary informational resources and direct participation in researched educational programs were applied. The development of educational tourism is promoted by the factors related to the environment of manor, historical place or nature as well as professional qualification, working experience, enthusiasm and ability to be flexible about customers’ needs of actors responsible for rural development. Volatility of demand regarding educational programs, lack of specialists and challenges related to cooperation were identified as problematic issues.

Today technological progress is reshaping global economic development and changing the overall welfare of societies. Therefore, it is important to assess challenges and readiness of the European Union to use its capacity to ensure that technologies benefit people and bring them towards more inclusive societies enhancing opportunities to use artificial intellect for making health, education, agriculture, services and manufacturing industries more efficient and user friendly. The Digital Economy and Society Index analyses the digital performance of the EU Member States across five main dimensions: connectivity, human capital, use of internet, integration of digital technology, digital public services. However, despite intention to jointly develop Digital Single Market, the gap between the EU top digital countries and less digitally advanced countries remains large. The aim of this paper was to evaluate the digital performance indicators of the EU countries, in particular focusing to Poland and Latvia to assess their progress and potential of their human capital’s digital skills. The research is based on theoretical literature studies on industrial revolution stages, European Union Commission documents, indexes and publications available in relevant public institutions such as ministries and industry reports. The research employed monographic method, analysis and synthesis methods as well as graphical data analysis. The research results give evidence that currently Poland’s human capital is significantly better prepared for making use of future digital economy challenges than Latvia’s human capital, and there is a close link between countries’ R and D expenditures proportion of GDP and their human capital’s readiness to integrate in digital economy.
