The landscape in Latvia is managed and planned in different levels and regulations. The survey has been undertaken in Latvia with the aim to assess the landscape as regards the aesthetical quality assessment in Latvian watermills and small-scale hydroelectric power plant territories by means of public perception. Duration of research was from May 2011 till March 2012. The method used in this survey is the public questionnaire method. Public notions concerning researched landscapes territories in Latvia reveal that the landscapes in these territories are mainly assessed critically; however, in the assessment of visual information from pictures taken in particular territories the results are different, and the value of these territories is mainly assessed positively. The contribution of Latvian people’s knowledge regarding improvement in the landscapes situations in researched territories of Latvia has to be realized.

The research was carried out on ASU WRI grounds in Juodkiškes village in Endocalcari Endohypogleyic Cambisol (CMg-n-w-can). Research basis is 3 different field studies. In Variant I an organic cropping system was used with manure and without mineral fertilizers and pesticides, in II - organic-mineral cropping system with manure and mineral fertilizers, using pesticides, in Variant III - mineral cropping system with mineral fertilizers and pesticides. Minimum mineral nitrogen content in soil was in the organic cropping system, and the total minimal field crop capacity - in the mineral cropping system. However, it has the highest energy efficiency of this system (ETK - 13). Minimal N-NO3 - concentration in drainage water was in the mineral cropping system. In the organic-mineral and organic cropping systems concentration of this compound increases by 11 percent (to 21.8 mg l-1). The minimal concentration of ammonia nitrogen was under organic cropping conditions. The organic cropping system showed the highest runoff and maximum leaching of nitrogen compounds by drainage.

This work focuses on the demands of scientific and sociopolitical understanding of situation of Latvia where the interaction between different languages and cultures have produced the political map of today. The aim of this work was to determine the differences of election results between rural areas and the city area, as well as to determine the main factors affecting election results in rural areas. Results of the study show that the ethnic factor has a major role in interpretation of the distribution of election results. If the proportion of non-Latvians increased by one percent, then the proportion of voters for Harmony Centre would increase by 0.64 percentage points in Vidzeme and by 0.75 percentage points in Latgale. Conclusions of the study: election results in rural areas differ significantly from the results in towns and cities, but the difference between rural areas and small cities is smaller compared to the cities under state jurisdiction; in rural areas, the national composition of the population has the greatest influence on the election results.

Agriculture is a unique sector, because it is associated with negative outcomes stemming from imperfectly predictable biological and climatic variables. These variables include natural adversities (for example, pests and diseases), climatic factors are not within the control of agricultural producers. So in agriculture it is very important to identify and evaluate risk, only then decisions made in farm will bring profit and other positive results. Scientific literature distinguishes a lot of methods for risk evaluation, but it is not clear what methods could be adapted in agriculture sector. This article presents main risk types in agriculture and their features as well as introduces most popular risk evaluation methods and their possible use in assessing risks in agriculture.

Farm financial distress can be determined by many factors. Farm failure can be the result of macroeconomic environment, unsuccessful farmer’s management decisions, and even natural forces. Different financial distress determinants may have different influence on a farm financial position. This study presents average financial ratios (leverage, return on assets, and return on equity) and single ratio of rental equivalent to gross margin according to farm size, land quality, economic size, farmer’s age and type of farming in Lithuania. The new approach to financial distress diagnosis requires classifying farms into financial positions. Considering average financial ratios and single ratio of rental equivalent to gross margin, farms were classified according to financial positions in order to estimate these methods’ suitability for financial distress diagnoses. Using study results, farmers can identify their position according to the average ratios. This study could be a guide for farmers making the financial management decisions.

Food consumption becomes an increasingly important topic considering global and local environmental problems as well as health issues and wellbeing of nations in general. Also in Latvia people are becoming more aware of importance of food and its direct and indirect impact on their everyday life. Therefore it is very important to evaluate sustainable aspects of food consumption and look for the barriers and drivers in order to form more sustainable consumption patterns which are based on information, knowledge and consciousness. The aim of the study is to investigate the perspective of sustainable food consumption in Latvia. The tasks of the study are: 1. to review present food consumption patterns from sustainability perspective; 2. to elucidate consumers’ understandings, attitudes and behaviour towards sustainable food consumption. The empirical research was based on the online survey with a sample of 82 women in the age group from 19-35. Descriptive statistics were used to analyze the results of the questionnaire and data obtained from Central Statistical Bureau of Latvia. The results of the study indicate the gap between positive attitudes towards sustainable food and stated purchasing behaviour. There is an obvious perspective of growth of sustainable food market if we increase the awareness of consumers regarding sustainable consumption issues.

Volunteer work has been identified as a relatively new kind of leisure activities. It plays an important role in various, at the same time it is a great possibility to learn, acquire new skills and accumulate human capital while taking part in volunteer activities. Therefore, the objective of the study is to research the policies related to voluntary work and their relevance in realization and development of volunteer work in Latvia. Theoretical literature shows that in Latvia the volunteer work is mentioned in some policies – economic, youth policies and civil society. In the framework of economic policy successful development of volunteering enhances the progress of economic processes in the state in two ways by making contributions to Gross Domestic Product; by accumulating person’s human capital, results illustrate that although the term “voluntary work” has a long history, infrastructure for realization of the voluntary work has not been developed in Latvia, and regulatory enactments do not cover voluntary work in an adequate manner. After the analysis the author believes that volunteering is widely discussed in the youth policy as there is law and a range of structured documents where aspects of volunteer work are mentioned. According to the results of research, in the frame of civil society it must be noted that in Latvia the voluntary work movement has to be examined in the context of the establishment of non-governmental organizations because voluntary work movement started to develop in a purposeful and organized manner only in 1998 in non-governmental organizations.

The article analyses organizational internal and external environments, their possible correlations with 4 components of sustainability, and the principal determination models for sustainability of organizations. Based on the general principles of sustainable development organizations, a model for the determination of organizational sustainability has been developed. The use of self-organizing neural networks allows the identification of the external sustainability of each forest enterprise and the endeavour to explore vital, social, anthropogenic and economical efficiency. The determination of the forest enterprise external sustainability is expected to help better manage the external sustainability of forest enterprises and explain the reasons for a respective level of external sustainability.

Environmental pollution that has been one of the key issues for decades has still not lost any of its topicality. In order to study the impact of air pollution on the growth of Norway’s spruce (Picea abies (L.) Karst.), 31 sample plots were established at different distances and directions from the pollution points in the Western part of Latvia. The plots were established starting from the year 2008 summer-autumn season and finishing with the spring of 2009. The selected stands were 32 - 171 year old and of different forest site types. The selection was used in the State Forest Service database and cartographic materials. Empirical data was obtained from each of the plots which reflected the environmental effects on the trees. To ascertain the effect of air pollution on the growth of Norway spruce, the algorithm based on additional increment to volume was used. Air pollution affects eating, regardless of age and the type of growing conditions. Pollution effects are closely related to the distance from the source.

It is essential to have information on the tree biomass due to the fact that it is an important ecosystem pool for reporting changes in carbon stocks of forests and increased attempts to diversify the energy sources. In Latvia, comparatively few studies have focused on this topic so far. Our study was conducted on two 36 - 38 years old Norway spruce plantations. Detailed stem analysis of 39 trees was performed, and biomass of the above-ground tree components was determined. We analyzed tree and clone-level biomass distribution, biomass relations with tree dimensions and dependence on the genetic factors. The mean total biomass (kg d.w.) of all analyzed sample trees was 131.4 ± 10.58 kg, the mean biomass of stem 85.9 ± 6.98 kg, the mean biomass of dead branches 8.3 ± 0.82 kg, the mean biomass of living branches 23.5 ± 2.34 kg and the mean biomass of needles 13.7 ± 1.22 kg. On average, 66.1% of biomass was allocated to the stem, 6.4% to the dead branches, 17.4% to the living branches and 10.1% to the needles. The biomass of the analyzed trees positively correlated with all tested tree parameters - DBH, tree height, stem volume. Typically, with increasing tree parameters total biomass and stem biomass increased rapidly but branch and needle biomass increased slowly. Significant differences of tree dimensions were detected between the clones, and the differences in total biomass and stem biomass were clearly correlated with the differences in tree dimensions over clones. No significant impact of the clone was found specifically on the tree biomass or its distribution.
