Northern Europe will be one of the locations where the renewable energy from forests could displace fossil fuels as a result of climate change: therefore, it will become more crucial to maintain renewable materials that also collect CO2. By taking tree biomass out of forest stands, we could create more renewable resources to use in practice, but this has certain negative effects on the forest ecology, including nitrogen leaching and vegetation degradation. The goal of the study is to investigate the effects of full biomass removal (FBR) in Norway spruce (Picea abies (L.) H. Karst.) forest stands and how this forest management affects vegetation regeneration, tree stock and carbon storage overall. The aforementioned structures were assessed at various forest ages. The central region of Latvia contains Norway spruce stands with all of the sample sites under study situated on drained peaty mineral soils and weakly aerated gleyic soils. As a result of the long-term evaluation, it was determined that the forest vegetation in FBR was similar to that in the same-age control stand (SAC) and that vegetation can successfully regenerate. The average tree height and DBH is lower in areas where stump removal and understory biomass was not carried out. Statistically significant (p<0.05) long-term influence of stump removal on the average height and diameter of Norway spruce can be identified in all parameters, except, tree height in Myrtillosa mel. forest type. Total biomass removal in long term has almost no significant effect on tree stand and vegetation regeneration.

Nowadays, different sun protective creams are available in the market, but most of them contain harmful synthetic chemicals and minerals which can induce skin allergies and premature ageing. Usage of sunscreens and photoprotectors of natural origin and natural antioxidants can reduce skin damage caused by excessive sun exposure. The effectiveness of the use of β-carotene — vitamin’s A precursor against excessive irradiation caused by oxidative stress cell damages has been proven of its very good antioxidative properties and leading to sooner regeneration of the skin after several environmental damages. Carotenoids and high value oil can be extracted from pumpkin (Cucurbitta spp.) by-products — peel and seeds with SC CO2. The objective of this study was to incorporate pumpkin seed oil (PSO) and carotenoid extract (CE) from pumpkin by-products in to facial creams for UV protection. Two types of creams with PSO and CE were prepared emulsion o/w and w/o. A cream without extracts and natural ingredients was used as control sample. The sun protection factor values in vitro (SPF = 0.92 to 1.18), total content of carotenoids (TCC = 1.08–17.95 µg mLE−1), β-carotene content (0.64–0.72 µg mLE−1), total phenolic content (TPC = 62.64–95.82 mg GAE gE−1), antiradical scavenging activity (11.26–43.66 %) and rheological behaviour of facial creams were determined. Although creams with CE and PSO show comparatively low SPF values, ß-carotene and phenolic compounds found in samples demonstrated very high antioxidant abilities valuable for skin protection.

Information technology is increasingly permeating the lives of every modern individual, profoundly impacting them as consumers. With e-commerce and online shopping now firmly entrenched in daily routines, it becomes imperative to conduct research and establish a comprehensive e-shopper/e-buyer profile. The purpose of this article is to study modern Internet shoppers in Latvia and describe the profile of a typical e-buyer to identify possible problems and prospects for the development of e-commerce for Latvian companies during the relevant period. The article highlights some aspects that characterize Latvian e-buyers and their behaviour as consumers, analysing their buying habits by age structure in dynamics and comparing data for the period from 2010 to 2021. The frequency of online purchases by Latvian users is also examined. The key characteristics of several basic portraits of the typical e-shopper in Latvia are substantiated. The analysis employs monographic and statistical methods, and visual images are presented based on Eurostat data. The research authors conclude that the Latvian segment of online buyers is rather conservative, but it is becoming more and more active in exploring the possibilities of online shopping. The key characteristics of several basic profiles of an average e-shopper in Latvia are also justified.

The Baltic States have a three-tier pension system. Pillar II is the state funded pension scheme in which contributions are made automatically from an employee’s gross salary as part of social contributions. The contributions to Pillar II state funded pension schemes may be invested in several pension plans with different risk ratios of which three types are the most common: active, balanced and conservative ones. The accumulation of funds and consequently a partial amount of an old-age pension depends on the chosen pension plan and the manager of funds. The research aim is to assess the operation efficiency of the state funded pension schemes in the Baltic States. The research mainly employs and provides the analysis on the statistical data on the value and return of assets and number of Pillar II scheme participants. Theoretical discussion is built upon the use of scientific publications by means of monographic descriptive method, correlation and regression analyses as well as the methods of analysis and synthesis. In Latvia, 25.62% on average of all state funded pension plans participants have chosen conservative strategy, while only 8.36% on average have chosen this strategy in Lithuania. In Estonia (75.49%) and Lithuania (69.13%), the majority of assets are accumulated in the balanced strategy pension plans. The research results show that pension plans have positive return in long-term; though, sharp fluctuations and negative return might be demonstrated in short-term. Both in Lithuania and Latvia exists a negative correlation between Pillar II pension schemes and inflation, i.e. the return of a pension scheme decreases with the increase of inflation meaning that inflation alongside with other economic and political factors might be considered as a factor affecting the return of pension schemes.

Performance is a concept which is critical to both conventional businesses as well as social enterprises. However, for the latter, performance is closely tied to social impact which social enterprises and governments supporting the social entrepreneurship field are seeking to achieve. Despite the criticality of the topic, in Latvia performance of social enterprises has not been analysed in detail before; therefore, this study serves as a valuable starting point for discussions and evidence-based policy and also as a benchmark for future development in the field. Research results indicate that the Latvian social enterprises regard their performance across the social dimensions to be stronger, compared to their results in the business/financial dimensions. A greater balance between the social and businesses/ financial performance dimensions is desirable, providing ample space for interventions aimed at strengthening the business skills and capacities of social enterprises, paying particular attention to those engaged in work integration.

It is generally estimated that gas, which generates more than half of the greenhouse gas (GHG) emission from waste industries in landfills, is seen as a serious environmental problem worldwide. It is therefore essential to promote management methods to reduce GHG emissions from landfills as well as other sources. One way of achieving this is the usage of different types of biocover applied to them. The aim of this study is to clarify the impact of the biocover created on GHG emissions. An experiment was conducted in laboratory conditions that studied the effectiveness of biocover developed in the laboratory. Three experimental columns with a diameter of 160 mm and a height of 1500 mm were created. Active compost saturated with water at a thickness of 500 mm was used as a source of methane, a permeable layer of sand at a thickness of 300 mm was further formed and finally covered with biocover. Biocover represented 60% of fine-fraction waste, 20% of soil and 20% of compost. The experiment was launched on June 6, 2022, and the first measurements were made two weeks later. All measurements were performed with the CRDS gas measurement device Picarro G2508 (Picarro Inc., USA California). All data analysis was carried out using Descriptive statistics methods. The largest reduction in emissions is projected directly for methane emissions, as biocover technology is appropriate to reduce methane emissions. Other GHG emissions are also expected to be reduced. NH3 emission measurements were also carried out to investigate the impact of the biocover on it. This experiment shows that the biocover created is effective and can be composed of material that has already been served. The experiment is intended to continue to obtain long-term data on the development of biotransformation and to develop more promising approaches in the future to reduce GHG emissions from landfills.

The topic of this article is relevant because in Lithuania the assessment of the area occupied by plantations and green spaces has shown that the area standards do not meet the requirements and recommendations of the World Health Organisation. Green spaces are regulated differently in different countries of the European Union. Lithuania has also developed a legal framework for the protection, management and establishment of new plantations and green spaces. However, this legal framework is im-proving and new laws are being added to it. Comparative, analytical, as well as statistical, and logical analysis methods were used for the investigation. The data of the Land Fund of the Republic of Lithuania for 2002–2022 were used for comparative investigation. The aim of this article is to perform an analysis of the change in the trees and shrubs greenery area of Lithuania in 2002–2022. In Lithuania, for example, trees and shrubs occupied 84,687.48 ha in 2002. In 2022, the plantation area amounted to 208,609.48 ha. From 2002 to 2022 the area of tree and shrub plantations in Lithuania increased by 123,922.00 ha or 146.33%. The analysis shows that in the period between the years 2002 and 2022 the biggest increase in the area of shrubs and plantations took place in Utena County (32,715.83 ha or 395.27%), but the smallest increase in Tauragė County (2,642.93 ha or 37.69%) and Marijampolė County (4,581.39 ha or 72.25%).The development of plantation areas has been positively influenced by the creation of an appropriate legislative framework and the implementation of plantation programmes in counties and municipalities.
