At different points in the history there have been attempts to evaluate the volume and value of separate game-related goods and services in Latvia; however, so far there have been no comprehensive studies covering the role of the game management and its impact on Latvia’s economy. Such data would be necessary not only to evaluate the impact of the game management on Latvia’s economy, but also to set appropriate priorities in cases where game animals cause damage to other sectors of economy. In order to evaluate the role of the game management in the national economy, lists of the game-related goods and services have been drafted, sources of information have been identified to determine the volume and monetary value of the goods and services in the 2009/2010 hunting season, as well as a methodology has been developed to acquire the missing information. It has been determined that the total monetary value of the game-related products was 3.66 million LVL, while the game-related services accounted for 18.86 million LVL. The total contribution of the game management to Latvia’s economy in the 2009/2010 hunting season has been estimated at 22.52 million LVL. Among the game-related products the most significant product is the game meat total amount (sales and own consumption) of which has been estimated at 2.8 thousand tons, while total value accounted for 3.6 million LVL. Among the game-related services the most significant contributors are the following: sales of hunting equipment (6.7 million LVL) and game-related transportation costs (4.7 million LVL).

Recreation services are the forests’ non-market goods which constitute a substantial part of the total economic value and are important for the choice of multi-functional forest policies. However recreational services do not always have a market price and comparatively less literature applies value orientations to examine issues concerned with recreational use of natural resources. This research reports on the findings of the comprehensive, national-level study about the contribution of forest recreational services to Latvia’s national economy in 2009 and about the respondents’ declared choices, travel costs and willingness to contribute some money for improvement of amenities in a forest. Two general information sources were used to obtain the information - available statistical data and the contingent valuation survey to estimate the respondents’ choices and habits for recreation activities in the forests. Results show that forest recreation is very popular and highly valued in Latvia. The statistical analysis confirms that the significant differences exist between varied respondents’ socioeconomic groups in their objectives, choices and preferences to use the forest recreational services.

Forest industry consists of two related industries forestry and wood processing. Wood processing industry, which is a direct consumer of timber resources generated by forestry sector is eager to search for an answer about kind and amount of round wood they can count on in long term period. In Latvia for every five years State Forest Service calculates cutting volumes for the state owned forests based on models which do not guarantee safe long term income maximization. Long term cutting volumes and assortments in privately owned forests have not been analyzed very deeply. The aim of the research was to estimate the hypothetic amount of different timber resources available in the territory of Latvia for wood processing industry within next hundred years and look at geographic location of timber resources and woodworking companies. Research results showed that forests in Latvia are not being depleted and current annual cutting volumes could be increased. Geographic observation of primary wood processing companies showed that most of them are located close to large cities or near main roads of Latvia. This location makes easier round wood deliveries to factory and facilitates transportation of produced goods to an end customer. To clarify where and what profile (softwood or hardwood) production volumes should be increased, model of timber resource demand indicator was implemented.

Due to currently aggravating problems of global warming, more and more alternatives are being developed using a mixture of different fuels. The rapid development of science and engineering solutions can be the most efficient burning of the local biofuels to a minimum harmful substances from combustion process - including the CO2 emitted into the atmosphere. The research concerns fuel problem of choice between cost-effective, but environmentally harmful fuels. Research data will help further studies on the fuel in order to increase energy efficiency and rational use. The research was done in 2010, in Riga Technical University laboratories. An aspen wood and hard coal was used to create this fuel mixture. During the research, sampling, grinding, sifting and blending of different proportions, moisture and calorific value determination were carried out. It was determined that the calorific value of the mixture would increase linearly, exactly in the proportion of coal quantities added.

Baltic States’ dairy sectors are important to their economies. All Baltic States have had substantial current account deficits that exceeded acceptable thresholds until the year 2009. The States are dairy product exporters. Export capability largely depends on international competitive position of dairy processing companies. Several factors, inter alia, company size determine the position. Largest companies have been formed by horizontal integration. At Baltic scale dairy processing is still fragmented. The aim of this paper is to evaluate economic effect aspects of integration related to exports in the Baltic States’ dairy sector secondary level. As the subject has not been explored earlier at company level, the author researched data of 188 annual reports of 53 Baltic dairy processing companies over the period 2003 to 2009. Descriptive statistics, time series analysis and regression analysis methods were primarily used. The author establishes that among dairy companies which generate significant exports turnover two-thirds are horizontally integrated and include all largest dairy processing firms in the Baltic States. A few smaller firms have succeeded in exporting due to suitable channel management. Among a large group of companies that generate less than 1% turnover from exports, 77% are non-integrated and all are small. Using regression analysis the author estimates that 1% increase in net turnover in the exporting dairy company group is expected to create 0.93 – 0.94% increase in net turnover from exports. Policies promoting mergers of some companies may thus lead to increased dairy exports, higher milk production and fuller realisation of economic potential of the sector.

The theme of landscape identity becomes actualized beside with the impact of globalization. Landscape identity is closely linked to the Latvian national identity. The concept of identity is multifaceted and touches on a number of scientific areas that currently in Latvia are actively investigating this phenomenon. Landscape investigators admit the multidisciplinary structure of the concept of identity, including in their researches the investigations of historical, visual and associative aspects. Landscape identity is related to detection, identification and definition of landscape elements, because landscape elements are the key to the perception of identity. The method of landscape identity assessment is based on three stages: the assessment of the historic, visual and cognitive elements in formation of landscape identity. The assessment of historic elements in formation of landscape identity is associated with the investigation of historic materials and description of structural elements according to the stages of development. The assessment of visual structural elements of landscape identity is based on the material collected during the field work by filling in the landscape assessment matrix. The assessment of cognitive structural elements of landscape identity is based on the opinion survey, which makes it possible to find out the concealed associative identity. The information obtained in all stages of landscape identity assessment forms the landscape identity model. The aim of the research is to develop the method of landscape identity assessment. The research was carried out at Latvia University of Agriculture in 2010.

The research was accomplished within the framework of the doctoral thesis, with the aim to clarify the role of Latvian Manor Park in the settlement landscape ecology. Significance of the Latvian Historical Park in the settlement landscape ecological processes in Kuldiga district was discussed and analyzed. To achieve set objective of the research, there was developed the landscape ecology assessment methodology of the settlements in the influence of the historical parks based on generalized scientific cognitions and researches in the landscape ecology, and scientific researches of the population loads and historical park value. The developed method was applied by surveying the selected historical parks in the settlement, and by assessing biodiversity factors, urbanization load, and landscape ecological networking compatibility degree. As a result, the selected settlements of historical parks were marked in the district of Kuldiga in the landscape ecological map, highlighting the importance of both national and European level. The results indicate significance of the historical parks in the settlement landscape ecology and that the role of historical parks in the settlement landscape ecology is essential, which ensures the natural basic resources air, water and soil quality. In the settlements, the historical parks existence is high value and quality environmental guarantee, which would have been managed according to the proposed principles of landscape ecology science.

Since the change of the paradigms of competitiveness is taking place now, the concept ‘competitiveness’ also changes its semantic meaning. In the article the concept ‘educator’s competitiveness’ is analyzed and scientifically substantiated according to different views. The aim of the article is to present the results of theoretical research, performed by author for several years in the field of concurentology, actualizing the new meaning of the concept ‘educator’s competitiveness’ in the pedagogy science and education, and proposing an insight into the substantiation of the philosophic methodological basis for the evaluation of educator’s competitiveness. In the article, the author applies the concept ‘educator’ according to its broader meaning. The research shows that there exists: 1) diversity in relation to the definitions and explanations of the competitiveness of an educator as a specialist; 2) three methodological approaches in the research of competitiveness: a biometric, a functional and a structural approach. According to the author’s opinion, the structural approach would be the most appropriate for the development of the evaluation methodology, including the system of evaluation indicators, in relation to the components of an educator’s competitiveness structure.

Lack of data about effect of meteorological conditions, sowing date, sowing rate, fungicide as growth regulator application and other agroecological factors on rape autumn growth is observed in Latvia. The aim of our research, started in autumn 2007 and continued up to autumn 2010 in Research and Study farm ''Vecauce'', was to investigate the influence of agroecological factors (sowing date, sowing rate and fungicide (as growth regulator in autumn)) application as well as meteorological conditions on autumn plant growth of two types of winter rape varieties. Winter rape biometrical parameters were estimated, and meteorological parameters (hydrothermal coefficient (HTC) and growing degree days (GDD)) were calculated. Four year results showed that winter oilseed rape seed germination was affected by precipitation and air temperature around the sowing time. Calculated GDD correlated with plant biometrical parameters during trial years. HTC showed moisture effect on rape emergence time. Sowing date was important factor which had strong and significant impact on biometrical parameters of rape plants in autumn. Earlier sowing date increased height of growth point, root neck diameter, plant and root mass, and main root length significantly for both cultivars in four trial years. Such agro-ecological factor as sowing rate (plant density) affected plant biometrical parameters only in some trial years. Plant weight was significantly influenced by sowing rate for both cultivars if sowing rates were equal. Other important parameter - height of growth point - was not significantly influenced by sowing rate for both cultivars when similar sowing rates were used in all years; exception was year 2009 for 'Californium'.

Research on identification of Ceutorhynchus spp. on winter oilseed rape in Latvia was done during the vegetation season of 2009 and 2010. Field trials were located in the Research and Study Farm ''Peterlauki'', Jelgava municipality, Latvia (56 deg 32 min 17.38N, 23 deg 43 min 17.65E). Four species of brassica stem weevils were identified: cabbage stem weevil Ceutorhynchuspallidactylus Marsh., syn. C. quadridens Pan., rape winter stem weevil C. picitarsis Gyll., blue stem weevil C. sulcicollis Pay., and C. typhae Herb. One of the most common species in winter oilseed rape was cabbage stem weevil C. pallidactylus. Use of a sweep net for identification of particular species cannot be applied, as in practice no specimens have been collected by this method. One of the most appropriate methods for identification of Ceutorhynchus spp. on winter oilseed rape has been yellow sticky traps and water traps that have been used to collect the greatest number of specimens (24) during the vegetation season. First pests appear during the 2nd decade of April, when the plant reaches 33 BBCH. Pest control using systemic insecticide Proteus 110 OD (tiakloprid 100 g LE-1, deltametrin 10 g LE-1) with a dose of 0.75 L haE-1 was applied when the plant reached 39-44 BBHC. Despite the high population density (2 to 10 insects on 40 plants), significant (p is less than 0.05) decrease in pest damage by 43-51%, when compared to untreated area, was recorded during vegetation seasons of 2009 and 2010. Pest control with a systemic insecticide when the plant is in the stem elongation phase provided a significant (p is less than 0.05) yield increase of 0.5 to 0.7 thaE-1.
