Lazdins, A., Latvian State Forestry Research Inst. Silava, Salaspils (Latvia) | Thor, M., Skogforsk - The Forest Research Institute of Sweden, Uppsala (Sweden)
This article is covering results of pre-commercial thinning, forest infrastructure and undergrowth harvesting field studies implemented in July, 2007 by Skogforsk and LSFRI Silava. A scope of the study was to estimate prime costs of biofuel production from small trees and to compare two types of harvester heads (Bracke C16.a and Ponsse EH25). The productivity in pre-commercial thinning expressed as trees per E0-h (effective hour) ranged between 53 (Ponsse) and 118 (Bracke) in the pine stand and 150 (Bracke) in the mixed spruce stand. In comparison the LVm3 (LV - loose volume) ranged between 9.9 (Ponsse) and 14.1 (Bracke) in the pine stand and was 13.0 (Bracke) in the mixed spruce stand. In the forest infrastructure (roadside ditches) harvesting productivity was 8.2 LVm3 E0-hE-1 for Ponsse and 12.5 LVm3 E0-hE-1 for Bracke. Productivity was economically insufficient in undergrowth removal, both in harvesting (Bracke) and forwarding (Ponsse) operations, respectively 1.1 and 2.6 LVm3 E0-hE-1. Prime costs of harvesting, forwarding, comminution and chip transport (50 km one direction) in pre-commercial thinning in calculation to LVL LVm-3 were 5.93 for Ponsse and 5.85 for Bracke. Prime costs in forest infrastructure in LVL LVmE-3 were 4.97 (Ponsse) and 6.36 (Bracke). Only Bracke was tested in the undergrowth, where prime costs were 37.55 LVL LVm-3. 'Environmental footprint' of biofuel production from small trees in terms of carbon (C) emissions ranged from 2.6 to 10.2 kg CLVmE-3, including road transport (50 km) to terminal.

2010
Tunkele, S., Latvia Univ. of Agriculture, Jelgava (Latvia) | Marcins, J., Latvia Univ. of Agriculture, Jelgava (Latvia)
The forests and woods are the main resources in Latvia. It is vital to understand the amount of wood resources that is being extracted from private forests now and in future in order to be able to predict the forest sector development and growth. The study objective was to identify the key factors in the wood resource availability and assess their role in private forests. In October 2009, the study was conducted to appraise the private forest owners the operational results and find out the future plans in connection to wood resource extraction. In the study a random sampling method was applied, where in the respondent selection the State Forest Service database information was used. In the study the respondent interviewing method CATI with computerized telephone interviews was used. In the selection of affecting factors the expert's method was applied. The study showed that only 25.40% of all private forest owners claimed that there was wood resources extraction in forests, but 29.50% of all private forest owners claimed that they were planning to perform the wood resource extraction in 2010. If the timber selling prices increased by more than 10 LVL per m3 in 2010, then 38% of all respondents claimed that they would increase the wood resource extraction in forests. The study data show that 30% of all private forest owners admit that there are growing stands in the forests, but they can’t be harvested, because road infrastructure is poorly developed or there are no roads in the forests.

2017
Novikova, A., Aleksandras Stulginskis Univ., Akademija, Kauno reg. (Lithuania) | Vaznonis, B., Aleksandras Stulginskis Univ., Akademija, Kauno reg. (Lithuania)
Agriculture not only supplies food and fibre to the society, but also provides other services, which are not revealed in the market prices. The role of agricultural activities is essential in forming and improving the landscape, in particular, for Lithuanian case study. Therefore, the paper focuses on development of the framework for estimation of consumers’ willingness to pay for agricultural landscape improvements. The objectives of this paper are to present construction of the estimation framework for eliciting willingness to pay (WTP) for non- market agricultural landscape goods through choice experiments (CE) in Lithuania; then, to show the results of framework pre-test, and identify applicability of the framework designed. CE is a survey-based method implying creation of repetitive choice situations about alternatives of agri-environmental schemes for revealing how inhabitants of Lithuania value public goods from agricultural landscape (scenic views, variety of flora and fauna species, recreational infrastructure and services, the objects of cultural heritage), enabling to estimate Lithuanian residents’ WTP and the demand for improvements of agricultural landscape. The results of the pilot survey have shown that the questionnaire was comprehensible and interesting to the respondents, revealing that the valuation of agricultural landscape is in demand by the society. The results of modelling, applying conditional logit, have shown a good model fit, allowing the usage of the estimation framework for the main survey and an estimation of consumers’ willingness to pay for public goods/improvements from agricultural landscape.

Jankauskiene, D., Klaipeda State Univ. of Applied Sciences (Lithuania);Latvia Univ. of Life Sciences and Technologies, Jelgava (Latvia) | Kuklys, I., Klaipeda State Univ. of Applied Sciences (Lithuania) | Kukliene, L., Klaipeda State Univ. of Applied Sciences (Lithuania) | Ruzgiene, B., Klaipeda State Univ. of Applied Sciences (Lithuania)
Nowadays, the use of Unmanned Aerial Vehicle flying at a low altitude in conjunction with photogrammetric and LiDAR technologies allows to collect images of very high-resolution to generate dense points cloud and to simulate geospatial data of territories. The technology used in experimental research contains reconstruction of topography of surface with historical structure, observing the recreational infrastructure, obtaining geographic information for users who are involved in preservation and inspection of such unique cultural/ heritage object as are mounds in Lithuania. In order to get reliable aerial mapping products of preserved unique heritage object, such photogrammetric/ GIS procedures were performed: UAV flight for taking images with the camera; scanning surface by LiDAR simultaneously; processing of image data, 3D modelling and generation of orthophoto. Evaluation of images processing results shows that the accuracy of surface modelling by the use of UAV photogrammetry method satisfied requirements – mean RMSE equal to 0.031 m. The scanning surface by LiDAR from low altitude is advisable, relief representation of experimental area was obtained with mean accuracy up to 0.050 m. Aerial mapping by the use of UAV requires to specify appropriate ground sample distance (GSD) that is important for reducing number of images and time duration for modelling of area. Experiment shows that specified GSD of 1.7 cm is not reasonable; GSD size increased by 1.5 times would be applicable. The use of different software in addition for DSM visualization and analysis is redundant action.

This paper summarizes the results of a theoretical study as well as practically oriented research about the concept of managing the social sphere of the village and considers the problem-perspective field of development the social infrastructure management in the villages of the Republic of Kazakhstan. The chosen topic is relevant as an insufficiently studied scientific problem, and also has practical significance for the well-being and stable development of rural areas. The study describes the scheme of management of the rural social infrastructure in the Republic of Kazakhstan from the standpoint of object-subject, methods and results. Interviews of the rural population were conducted about the satisfaction with the rural social infrastructure and attitude towards the work of local governance. Rural settlements of Mangystau oblast currently have an average not significant level of social infrastructure development and the level of satisfaction of residents in different areas with its condition varies from very low to sufficient. The most important principles for the development of definition of rural social infrastructure management and its functions have been highlighted with the help of a comparative analysis of various approaches. According to the results of the study, it was concluded that the development of promising directions of management the rural social infrastructure requires a comprehensive study and evaluation of the facilities, mechanism and principles of this management and the identification of its current problems with regional development tasks.

2018
Straupe, I., Latvia Univ. of Life Sciences and Technologies, Jelgava (Latvia) | Liepa, L., Latvia Univ. of Life Sciences and Technologies, Jelgava (Latvia)
Green infrastructure (GI) is a strategically planned network of high quality natural and semi-natural areas and provides a range of ecosystem services and protects biodiversity in urban settings. It is very important to increase understanding of the role of GI from a scientific and a socio-economic perspective. The main goal was to understand and assess the ways that tourists use from experiencing urban green infrastructure in the cities they visit. An interview questionnaire survey took place among tourists of the following countries and cities: Latvia (Riga and Jelgava) and Portugal (Lisbon and Faro). The questionnaire includes perception, psychological aspects and preferences, behaviour and activities and general questions as well as biographical information about tourists. The study represents that no significant differences have been found between respondent groups in Latvia and Portugal. The results of the survey show that in future there is a need to improve the linkage between GI and social-cultural activities in cities. Therefore, studies for tourists’ perceptions, preferences and uses of GI will provide the alternative management approaches for urban planning and tourism development in future.

2015
Vaznoniene, G., Aleksandras Stulginskis Univ., Akademija, Kauno reg. (Lithuania)
This article presents analysis of the role of rural community in enhancement and implementation of changes in rural social infrastructure. Rural social infrastructure is a key part of rural social and economic system, the development level of which predetermines satisfaction of needs of rural residents, fulfilment of their range of choices and alternatives. The main objective of this article is to deploy the fact that application of “bottom-up” approach could stimulate rural community to make decision intended for promotion of positive changes when straining after the attractiveness of their locations through the rational development of social infrastructure facilities, supply of target, high-quality and multiple services. The following research question has been addressed – what is the potential contribution of rural community towards promotion of changes in social infrastructure of rural areas. The research aim is to disclose the role of rural community in enhancement of rural social infrastructure changes. An anonymous survey using questionnaire was implemented in five pilot rural areas and the summary of results is presented. It has been determined that activity and citizenship of rural community in assumption of liabilities for the wellbeing of all rural residents predefines the relevancy of their decisions and opinions before the local authorities and other concerned local or regional institutions. Consequently, the challenge for mentioned rural development actors is to identify or recognise the constraints on rural community participation in forming social infrastructure at local level, and to develop and enable specific initiatives in their favour.
