In order for GDoFVA to develop its policies, it is necessary to identify the economical contribution of its practices at the local, regional and national level. To create awareness of the economical dimensions of the GDoFVA Solar Energy Systems practices, by assessing its contributions to the economy of the local, regional and national economy. The study takes within its scope the economical contributions of the GDoFVA Solar Energy Systems implemented in the forest villages in Turkey by taking into consideration the data from the forest villages of the Western Mediterranean Region. Written resources regarding the topic was obtained from related public organisations and institutions by the screening method. Unique data was collected with questionnaires developed for face to face interviews. The SES practices were implemented for 3,447 families in a total of 152 forest villages in the Western Mediterranean Region. A sample of 15-20% of the population of each village with the SES was obtained. According to the number of families for which the SES was implemented in the forest villages of the region between 2005-2011, the practice leads to a total annual saving of 10,800 stere. The SES practice has been implemented nationwide to 145 thousand families. According to this, the total annual contribution for the nation is 454 thousand stere. This amount shows that there is approximately an annual saving of 340.5 thousand m 3 of wood.","PeriodicalId":197799,"journal":{"name":"Eurasian Journal of Forest Science","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-02-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116519579","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"Assessing forest governance in Albania","authors":"Albora Kacani, Leonidha Peri","doi":"10.31195/EJEJFS.473633","DOIUrl":"https://doi.org/10.31195/EJEJFS.473633","url":null,"abstract":"In the last 20 years, Albania has transferred the ownership and the responsibility of the management of 80% of forest area from central government to local government. The process was part of a wide decentralization reform aiming to tackle the challenges related to illegal logging activities, weak institutions, and capacities, unclear laws and regulations, frequent reforms in forest administration, high sector informality etc. Due to decentralization forest governance involve two levels of government and a range of stakeholders with different interests (local communities, forest owners, private sector, etc.). Although the reforms are under implementation, there is a lack of assessments, to analyze the governance challenges for the sector. Therefore, the aim of this paper is to provide an assessment of the status of forest governance in Albania, using a comprehensive analytical framework developed by FAO and PROFOR. The framework is based on three columns (i) policy, legal, institutional and regulatory frameworks, (ii) planning and decision-making processes and (iii) implementation enforcement and compliance. A set of 84 indicators, considered to be relevant for Albania, has been chosen out of 130 indicators proposed by PROFOR. The assessment is carried out through a survey, with a cross-section of 30 experts from various forest-related institutions (state and non-state). The results show that forest governance in Albania is far from good forest governance, despite some positive efforts. The reasons for this are no clear set of policy directions, conflicting or confusing laws, complex forest law and bylaws, no secure access to forest resources by local communities, low capacities of government (central and local) and non-government stakeholders, lack of transparency and accountability etc.","PeriodicalId":197799,"journal":{"name":"Eurasian Journal of Forest Science","volume":"75 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-02-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125449921","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The pine plantations were selected at ages of 3, 10, 20 and 30 in Biga (Canakkale-Western Turkey) to harvest adequate sampling plots and the natural sampling plots were settled to the vicinity of the plantation plots. The soils were investigated in terms of chemical such as pH and EC (µS/cm) and physical such as soil volume weight, fine soil weight and skeleton weight (g/L) which were taken from 0-5 and 5-15 cm depths from 9, 5, 8 and 8 sites (30 sites in total) for 3, 10, 20 and 30-year-old sampling plots. We assumed that, plantation causes decrease at pH, EC, soil volume weight, fine soil weight and increase at skeleton weight which would have occurred because of tillage and in contrast, the soils in natural sites, should have the opposite properties of plantation sites. The results revealed that; pH was lower in natural plots than plantation at 20-year-old sites (no significant difference in other plots), EC did not show any significant difference between natural and plantation sites. Soil volume weight was higher in plantation plots than natural lands at 10 and 20-year-old sites; fine soil weight was higher in natural land which is in concordance with our hypothesis; and skeleton weight of natural sites was one third of plantation sites. The results showed that; soil chemical and physical properties do not alter immediately after the plantation of a natural site but is an efficient factor on soil.","PeriodicalId":197799,"journal":{"name":"Eurasian Journal of Forest Science","volume":"234 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-12-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125750407","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Turkey agricultural sector today is developing with new techniques and products. One of the best examples of this; is the production of vermicompost and its use in agriculture. Turkey is in Asian and European continents (Eurasia) with the population approximately 81 million. Turkey has 24 million hectares of agriculture land (excluding pastures+ meadows, including total arable land and under permanent crops). There is little data available on vermicompost production in Turkey. The production of vermicompost started after 2011. The average solid vermicompost production in the 2017 was about 20000 tonnes produced by 15 plants with official production permit by the Republic of Turkey Ministry of Agriculture and Forestry. Apart from this information, it is estimated that there are approximately 4200 unauthorized vermicompost producers in Turkey. The production of liquid vermicompost in Turkey is limited. A few producers also produce worm-tea in the country. On the other hand, livestock activities also increase day by day and a lot of waste comes out. It can be said that the most rational method for evaluation of waste is to produce vermicompost. Vermicomposting is an environment friendly process used to convert organic waste into valuable agricultural product. The interest in the vermicompost is increasing day by day in the whole country. As far as the vermicompost production is concerned, Turkey has a new specific legislation and published by the official newspaper no 30341 dated 23 rd February 2018. There are two big legally authorized associations in the country today. The number of academicians engaged in academic studies a vermicompost is limited and interest in the vermicomposting is increasing. One of the biggest companies producing solid-liquid vermicompost and all related machines is operating in Tekirdag province and this company has the largest production capacity of Turkey. The company operates by consulting with academicians who are experts in vermicomposting. The results of academic studies on vermicompost showed that there are many positive effects on soil quality and plant growth. However, many other benefits of vermicompost on soil-plant systems are not yet fully understood. The use of vermicompost is important for the sustainability of agriculture. The main aim of the paper is to demonstrate and share reasonable causes for the increased interest in vermicompost and earthworms. For the vermicompost sector by 2023 Turkey aims to be among the top three overall producers globally.","PeriodicalId":197799,"journal":{"name":"Eurasian Journal of Forest Science","volume":"53 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-12-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124481335","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, low-intensity surface fires and their effects on soil properties have been relatively less studied in comparison to moderate to high-intensity crown fires. In this study, the effect of a surface fire on the chemical and biological properties of soil with a thick organic layer was investigated in a mixed forest stand dominated by Castanea sativa , Fagus orientalis and Pinus nigra ssp. pallasiana in Bursa Province, Turkey. Soil samples were taken from burned and unburned (control) sites in three periods: December 2011, July 2012, and November 2013. Samples were analyzed to determine some chemical and biological properties in the soil. We tested the effect of fire and period on each variable by two-way ANOVA analysis. The results indicated that Nt and OM were not affected by fire, while C / N ratio decreased. The difference between the periods was significant as regards OM and acid phosphatase enzyme activity. Fire resulted in a significant increase in soil pH, Ca, Mg and no significant change in P 2 O 5 . Although we found that surface fires limited the effect on soil properties, we concluded that there might be positive interactions between increased available nutrients in the soil and the burning of soil with relatively low severity. Prescribed fire can be proposed as a management tool to mitigate fire risks and short-time enrichment of available soil nutrients in these ecosystems.","PeriodicalId":197799,"journal":{"name":"Eurasian Journal of Forest Science","volume":"206 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-12-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114298117","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
