Vietnam aims to transform its food systems in a transparent, responsible and sustainable manner. To help achieve this, the new CGIAR research initiative “Sustainable Healthy Diets through Food Systems Transformation” (SHiFT) is working with the emerging multi-stakeholder platforms in the country in order to support the planning and implementation of specific activities. This article demonstrates success already achieved.

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.

Semi-natural grasslands (SNG) are essential in the context of farmland biodiversity. The Common Agricultural Policy (CAP), on the other hand, is an important tool for the continuation of the management of semi-natural grasslands. Explicit knowledge on the pattern of grassland area changes is important to foster a more effective use of CAP for grassland biodiversity conservation. Our aim was to determine the habitat-specific changes in the distribution of Latvian SNG across different management regimes. Based on state-owned geospatial data of SNG distribution in 2014 and 2022, we assessed changes in semi-natural grassland areas over nearly ten years by analysing grassland management and spatial distribution including areas inside and outside the Natura 2000 network. The spatial distribution of SNG remained similar in both periods. Eastern Latvia retained the highest share of SNG while the central part showed the most pronounced increase in new localities of SNG due to extensive habitat mapping carried out in recent years. Abandonment appeared as a more important threat to SNG in the Natura 2000 network and more profoundly to unproductive habitat types while transformation into arable land and grassland intensification was a considerable threat to SNG outside the network and to more productive habitat types. We suggest that agri-environment schemes should address the different needs of SNG in the Natura 2000 network and outside it.

The use of the smoke released during the wood burning process to prepare food products is a centuries-long tradition, practically all over the world. However, during the combustion process, a group of compounds called polyaromatic hydrocarbons (PAHs) are formed in the flue gases, which are carcinogenic and condense during the smoking process and diffuse into the smoked food product. Therefore, permissible PAH norms have been set for food producers, which significantly complicate the use of wood. In the study, using a gas analyser, we measured the flue gases released during the burning of specially made, apple and grey alder wood pellets, with and without enrichment of the supplied air with ozone. The use of ozone does not ensure a higher burning temperature of pellets, but it stabilizes it – temperature fluctuations are significantly wider using non-ozonised air (697 to 817 and 611 to 817 ℃, respectively). The content of CO2, CO, as well as CH4 and N2O increases significantly in apple wood flue gases using ozonised air, while CH4 increases and N2O decreases in grey alder smoke. Which generally indicates specific reactions with ozone during combustion. Comparing the flue gases released during the burning of apple and grey alder wood pellets, grey alder smoke contains significantly more N2O and CO2 than apple wood pellet flue gases. On the other hand, using ozonised air in the combustion process increases N2O significantly in the flue gas of apple tree pellets compared to white alder.

Mortality rates and co-morbidities are high in people with psychiatric disorders. These patients have unhealthy dietary habits, which include increased consumption of fast food, snacks, sweets, saturated fats, and reduced consumption of protein, fruits, vegetables, and legumes, which contributes to the risk of developing chronic diseases such as obesity, type 2 diabetes, and cardiovascular disease. Unhealthy and monotonous eating habits lead to a significant lack of nutrients such as protein, omega-3 fatty acids, B-group vitamins, and fibre. The aim of the literature review is to investigate the main diet problems of patients with psychiatric disorders and, based on the studies on the nutritional value of legumes, to evaluate their suitability for the development of new products for patients with psychiatric disorders. Studies show the beneficial effects of legumes on the regulation of rapid fluctuations in cholesterol, blood pressure, excess body weight, and glucose levels, which in general delay the formation of inflammation and reduce the risk of psychiatric disorders. The benefits of legumes are due to their high protein and fibre content, low fat content, and content of iron, copper, magnesium, zinc, and B-group vitamins. In addition, legumes contain bioactive compounds that contribute to the prevention of chronic diseases.

Today the demand for plant-based protein is growing rapidly due to increased awareness of animal protein growing costs and limited supply and has been highly related to biodiversity loss, climate change, and freshwater depletion. Legumes are in demand for their high content of protein, minerals, vitamins, and carbohydrates, also including dietary fibre. Legumes are rich not only in macronutrients and micronutrients but also contain anti-nutritional factors. One of the most important anti-nutritive properties of legumes is their high trypsin activity. The length of time required for the preparation of legumes has limited their frequency of use compared to recommended intake levels. By heat treatment, an anti-nutritional component in legumes can be mostly separated. The possibility of using extrusion cooking, microwave dryer, roasting equipment, etc., is widely studied. Roasting is one of the widespread methods for treatment of legumes that significantly enhances the texture, flavour, colour, and product appearance. The latest studies in the legume treatments report valuable results after the combined treatments, wet roasting, which includes: dehulling, soaking, and roasting. Heat treatment can be a potential way to improve legumes use in food production: reducing the time required for treatment, preparation and improving nutritional value. l

A review of the available literature revealed that there was no information about public opinions on start-ups; therefore, the authors set the main aim to theoretically examine the nature of start-ups and identify the opinions of residents on start-ups in Latvia. The specific research tasks were defined as follows: 1) to conduct a theoretical review of literature on start-ups and the ecosystem thereof in Latvia; 2) to identify the knowledge and opinions of residents aged 18 to 75 about start-ups in Latvia. As part of the present research, the authors conducted a survey in Latvia to identify the population’s knowledge of start-ups, differences between start-ups and other kinds of enterprises as well as the role of start-ups in entrepreneurship. The research employed the monographic and descriptive methods, the descriptive statistics method and a sociological method – an Internet survey using quota sampling. The survey was conducted in January 2023 and involved 1005 respondents throughout Latvia. The survey found that most of the respondents (73%) generally knew or had heard about start-ups and, according to the respondents, the main features that distinguished start-ups from other kinds of enterprises were innovation (54%), use of modern technologies (48%) and fast growth (41%). 63% of the respondents who had heard about start-ups noted that the start-ups, compared with other kinds of enterprises, were generally important for further development of the business environment in Latvia.

Social enterprises, as an interdisciplinary form of business, often face problems that traditional enterprises and civil society organizations have already overcome: lack of legal framework, complex business models, business identity problems, lack of public awareness, lack of visibility and difficulty in accessing investment markets. The name ‘social entrepreneurship’ makes it clear that it is not easy to have a business oriented towards a social goal, because ‘social’ implies that the business is directed to the goal of reducing social problems and enhancing the quality of life, which, besides being expensive, is also a complex process. The purpose of the article is to reflect the challenges faced by representatives of social entrepreneurship in Latvia: before April 1, 2018, when this type of business was non-profit, and after, when the opportunity was given to establish a profit-making social enterprise. In order to achieve the goal, following tasks are set — to provide a theoretical explanation of social entrepreneurship, as well as, with the help of empirically obtained information, to reveal the challenges faced by representatives of social entrepreneurship in Latvia. According to interviewed informants, the main challenges for social entrepreneurs in Latvia are the lack of qualified employees, institutional cooperation and funding, which would allow organizations to effectively carry out their business; in addition, difficulties are caused by situations when financing is too complex or difficult to access, and social entrepreneurship lacks public support. Rather often, social entrepreneurs lack knowledge about business risks and how to plan their business in the long term.

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.

Tourists’ environmentally responsible behaviour (ERB) in response to climate change is a topic that is becoming increasingly important during the Covid-19 pandemic as people’s values change. Tourism is facing an economic downturn and now is the time to prepare for a new upswing. Meanwhile, a new narrative is needed in response to climate change, as tourism is a net polluter of the environment. That is why tourist ERB studies are becoming more and more relevant in the world, including Latvia, too. The objective of this paper is to determine the ERB of tourists in response to climate change. The questionnaire included 30 research questions and generated 383 answers from respondents from the Vidzeme region of Latvia. Several research methods were used in the study: descriptive and correlation method, KMO and BARLETT’S, Cohen’s Kappa and Cronbach’s alpha tests, Exploratory factor analysis and Principal Components Analysis. The study found that the factors attitude, behaviour, awareness, control, environmental knowledge, experience and values influence tourists’ ERB; however, environmental knowledge and experience show a slight advantage. To direct the continuation of the research towards the creation of the tourism ERB model in Latvia.
