Challenges for modern society encourage the interest of how the regions could increase opportunities to accelerate social and economic development and reach the level of developed regions. Especially it is important for rural areas. There is a search for new answers (ideas and innovations) on creating a competitive advantage of regions. Seeking for a better systematic (not chaotic) result of innovative activities various organizations (even working in different sectors) are tied up with other organisations by tight links in their regional innovation system. The collaboration among different organizations is argued to be the main axis for the stimulation of innovativeness. Besides, all innovative activities must be reinforced by organizations’ absorptive capacity (i.e. abilities to access external knowledge, anchor and diffuse it) that leads to innovativeness. This article argues the theoretical and empirical approach of how the regional development could be accelerated by empowered innovativeness as a capacity of participants of a regional innovation system. Lithuania as a modern country and the EU member declares the importance of the reduction of internal regional disparities. Consequently, the analysis of a particular regional innovation system, i.e. Šiauliai region, allows disclosing the regional peculiarities and weaknesses of its innovative activities limiting the development process. The goal of this article is to reveal the current situation of innovativeness in Šiauliai region and draw the directions of its empowerment for further regional development. The article consists of two parts: theoretical insights and explanation of methodological approach; and the presentation and discussion of quantitative research results.

The European Union livestock sector is a major player of the agricultural economy and its land use, and livestock is one of the fastest-growing sectors in agriculture, potentially presenting opportunities for economic growth and poverty reduction in rural areas. In Latvia, the year 2014 was quite difficult for the dairy industry both due to Russia’s embargo on dairy product import and low milk purchase prices and due to concerns that milk quotas had been exceeded. It is therefore important that cows are healthy and no additional losses are suffered from mastitis. Mastitis is a complex disease involving many factors, which is mainly caused by bacteria and there is no simple model that encompasses different possible aspects. Therefore, the research aim is to assess the effects of mastitis in cow herds for farms in Latvia. The research study proceeds in two stages or phases: firstly, to review the scientific literature on mastitis problems and solutions to the problems in other countries, secondly, to survey dairy farms of various sizes in the regions of Latvia in order to examine the real situation concerning mastitis and its effects on the economy of farms. A survey results of 74 farms in Latvia revealed that 90.5% of the farms had problems with mastitis. Consequently, if sick cattle are timely culled, it is possible to keep the herd milk yield without a significant drop. In case of cows with mastitis, farms suffer losses from smaller quantities of milk produced depending on farming intensity and due to cows culled with mastitis.

Considering the deficiencies of social services for the elderly in governmental institutions and growing demand of ensuring services in rural areas, the paper aims to assess the needs of elderly people for social services in the selected rural areas and to propose the social services’ development opportunities in terms of domestic help for the elderly. The social services facilitate support to elderly dependents in their homes, without interrupting their relationships with the family and the community, and improving their quality of life. The survey has shown that the municipality usually satisfies only basic biological needs of old people in rural areas. In order to ensure the well-being of elderly people, a complete cooperation among governmental and non-governmental institutions is required. Development of the services should be focused on the provision of the domestic help services for elderly people who do not receive them, and the diversity of the services for those residents who receive services from the municipality. The implementation of the development project of the domestic help services would enable the elderly residents of the rural municipality to have access to the most necessary services at the required frequency and intensity, considering the recipients’ needs, thus improving the quality of life of the elderly people of local community and ensuring their dignified ageing.

Energy transition from the fossil fuel dominating to the one based on renewable energy sources (RES) takes acceleration with the internationally recognised need to stabilise the global warming. Therefore, there is a general consensus that the initiative of the wide use of RES is manifold in its nature making an impact not only on the environmental issues, but also adding to the so desired customer involvement and rural development as well. Rural dimension in reaching the EU targets should arguably be a priority as RES utilisation is decentralised in its nature. Despite the fact that EU with its main strategic documents gives a clear direction on RES utilisation through wider involvement of citizens, especially in rural places, there are certain grounds for stating that a current situation and future insights among EU Member States still differ. Lithuanian case was chosen to explore the sustainability gaps regarding the RES utilisation development in rural places. Literature review is employed to choose the most suitable way aiming to explore and evaluate the RES utilisation development in rural places regarding the sustainability issues. This article adds to understanding and evaluating the main obstacles of the well balanced RES utilisation development in rural places.

Prolonged summer drought periods are forecasted for the Baltic Sea region during the 21st century, thus increasing the risk of drought stress of saplings used in forest regeneration. Nevertheless, the vitality of young stands might be increased by the selection of suitable planting material. The aim of this study was to estimate the effect of changes in distribution of summer precipitation on height increment, biomass distribution and root morphology of Scots pine and silver birch planting material commonly used in the forest regeneration in Latvia. Containerized pine and bare rooted birch saplings, planted in three different soil types, were subjected to altered distribution of summer precipitation, provided by the use of automated shelter. Sheltered saplings were weekly irrigated with the sum of precipitation of a corresponding period, while afield planted saplings had an unchanged precipitation regime and served as control. Height increment was measured once per week and estimation of morphology of saplings was done after the end of every vegetation season. Significant (p is less than 0.05) differences in height increment, and shoot and root biomass were observed among the same planting material in different irrigation regimes and soil types. In the control plots of peat soil, pine had a significantly (p is less than 0.05) larger height increment while birch-significantly (p is less than 0.05) smaller compared to experiment. Forecasted longer drought periods might reduce the growth of Scots pine in fertile forest types but silver birch growth might be affected in fertile mineral soils in future.

Climatic changes are shifting the potential tree distribution limits of many tree species northwards. One of such species is Fagus sylvatica, currently represented in Latvia only by a few stands. In order to increase knowledge on its potential use in the forest management, the aim of our study was to characterize the growth of beech in a young stand in the central part of Latvia. The stand of beech and spruce, mixed in rows with an initial spacing of 2.5 x 2.5 m in Oxalidosa forest type was assessed. Survival of European beech in clear cutting was similar to that observed for the native Norway spruce (73% and 79%, respectively), but both height and diameter were notably and significantly superior for wildlings at the mean age of 15 ± 2 years, reaching on average 7.4 ± 0.30 m and 8.9 ± 0.69 cm, respectively. Increasing ring width with increasing tree age for both tree species was observed until the last four years, when large and increasing superiority of beech over spruce, coinciding with reduction of ring width of spruce, was noted. It was most likely caused by intensified competition due to very wide crowns formed by young beech trees in the plantation with wide spacing: average crown radius reached 2.4 ± 0.16 m, for few trees exceeding even 4 m.

Latvia at the moment does not have precise data about long-term storage of Scots pine. Long-term storage in warm season may lead to significant damages for high priced timber, income reduction for timber sellers and quality loss risk for timber buyers, therefore, roundwood is transported as soon as possible, because of the risk of blue stain, crooks and insect damages. Results of this study on Scots pine were obtained during summer–autumn season of year 2015. Scots pine timber quality changes in long-term storage were analysed in 4 sample stacks – set up in summer (25 July) and stored for 100 days. In every sample plot there was a control pile, a pile with harvester spike damages, a pile with bark damages and a pile with harvester spike and bark damages. There were 32 timber assortments in every pile in order to determine also the emplacement effect in stack. In this study a high correlation was found between pine timber quality changes and meteorological conditions, side surface damages and storage length. By analysing the proportion of blue stain in cross-section and its changes during storage between control assortments and assortments with bark and harvester damages, significant differences were observed, therefore it can be concluded that not only bark damages influence the proportion of blue stain, but also harvester spike rollers. Based on the results of this study, we can predict maximum storage duration during summer–autumn period in Latvia, and it is set from 9 – 16 days.

Fast-growing hybrid aspen clones are recommended for establishment of plantation on abandoned agriculture land in Northern Europe. In this study we assessed the productivity, quality and assortment structure of hybrid aspen clones at final felling. Data were collected during the hybrid aspen clonal experiment conducted in the central part of Latvia. Large variation in the productivity level between different clones was affected by growth and survival. From the compared 5 most and least productive clones, based on the yield m**3 haE-1, the faster growing clones have about 17% better survival rate at age 10. Also, the mean annual increment (MAI) differed notably and significantly (p is less than 0.05, α = 0.05) between hybrid aspen clones at the age of 18 years ranging from 7 to 34 m**3 haE-1 yearE-1. Theoretical assortment structure of hybrid aspen at the age of 18 years was the following: 43 ± 4.86% of small dimension saw logs (SDS logs), 21 ± 4.86% high quality saw logs (HQS logs), 18 ± 4.33% pulpwood, 4 ± 0.77% firewood and 13 ± 0.08% of logging residues (tops). The outcome of HQS logs on average is more than 30% from the 5 best clones and further increase can be predicted with age. Stem volume (H2 = 0.32), height (H2 = 0.47) and quality parameters (stem straightness - H2 = 0.73, branch angle - H2 = 0.60) had a high heritability and large differences between clones, indicating notable possibilities to improve the productivity of plantations via selection of the best-growing genetic material.

Impact of a variety of forestry machine types on soil compaction is evaluated in this study according to the measurement of soil penetration resistance at 0 to 80 cm depth. It is concluded in the study that soils with poor bearing capacity (PBC), comparably small penetration resistance and organic layer thicker than 5 cm are less vulnerable to soil compaction. The use of small-size forwarder Vimek 610 allows to reduce soil compaction to an insignificant level in comparison to the control sites, and most or ruts disappear within a few days in PBC conditions. Whereas John Deere 810E, which belongs to the middle-size class of forwarders, significantly compacts soil through the whole measured depth in similar conditions. Rottne F10B and John Deere 810E forwarders represent the same weight category, and soil compaction due to the use of these machines on soils with moderate bearing capacity (MBC) is similar too; however, on soils with weak (WBC) and good (GBC) conditions results are different, mostly due to a different amount of extracted roundwood in both trials. Tracked forwarder was used only in GBC conditions and the results demonstrated significant compaction only down to 22 cm depth. The trials confirm that the depth of the intensity of impact depends on the weight of the machine and amount of material extracted; however, additional measurement data are necessary to characterize the impact quantitatively in different conditions.

The aim of this paper is to evaluate ecosystem services in riparian forests of Latvia using benefit transfer method. The core of benefit-transfer method is to transfer economic costs from one economic situation to another by using pilot indicators, thus saving time and monetary resources of the research. This method also is applicable for transfer of value of ecosystem services to research territories where such values have not been set. As to the evaluation of ecosystem services in riparian forests, data derived from these indicators are compared with the situation in riparian forest stands. Successful application of this method depends on the quality of existing research and their transferability. For example, the data on research of non-timber values can be used to set these values in riparian forests. Value of ecosystem services for 1 ha riparian forest stand in Latvia judging by 1) N and P removal (N - 8.14 euro haE-1 yE-1; P - 2.16 euro haE-1 yE-1); 2) Valuing carbon capture (478.6 euro haE-1 y-E1); 3) Valuing noise buffering (2.02 euro haE-1 yE-1); 4) Valuing air purification (NOx - 1332.5 euro haE-1 yE-1, NH3 - 216 euro haE-1 yE-1, particulate matter - 792 euro haE-1 yE-1); 5) Valuing pollination (timber - 15.25 euro haE-1 yE-1, non-timber - 4 euro haE-1 yE-1) total at 2850.67 euro haE-1 yE-1, which is significantly more than just the traditionally viewed timber value.
