Abstract: Bulgaria has developed national emission reduction strategies for the period from 2020 to 2029 and the years after 2030, in accordance with EU Directive 2016/2284. Our fundamental aim in this study is to assess the effects of the strategy on the PM near surface concentrations in Bulgaria. All the simulation was done by the modeling system U.S. Environmental Protection Agency (US EPA) Models-3 for 2008 to 2014 period and with 9 km horizontal grid resolution for the selected region – Bulgaria. The meteorological background that was used is with 1°x1° resolution from the National Centers for Environmental Prediction (NCEP) Global Analysis Data. There are 5 emission scenarios structured: 2005 emissions (reference period), 2020–2029 emissions projected with existing measures (WEM) and with additional measures (WAM), projected after 2030 WEM and WAM emissions, as parallel calculations were performed with all of the scenarios. Making parallels between the concentrations, with different scenarios simulated, gives the possibility to evaluate the national emission reduction strategies’ effect.

Spatial analysis of public attitudes towards domestic leisure tourism in Bulgaria https://geostudies.net/article/115877/ GeoStudies 1: 11-25

Abstract: Tourism is a very important sector for the Bulgarian economy with its GDP share varying between 10 and 13% before the COVID-19 health crisis. In 2021 domestic tourism accounted for 89% of the personal travel expenditures of Bulgarians. The purpose of the present paper is to analyse public attitudes towards the domestic leisure tourism in Bulgaria and its spatial distribution at the NUTS-2 regions and the residence place type level. The data used in the research are from a national representative survey based on a two-staged random sample stratified by the Bulgarian districts and the residence place type (capital, district administrative centre, town and village). The methodology includes: literature review, descriptive analysis, spatial analysis, average values, building one- and two- dimensional frequency distributions, statistical hypothesis testing, etc. The indicators used in the paper are: practices for domestic leisure tourism, stay duration in domestic resorts, frequency of domestic leisure tourism, people not practicing domestic leisure tourism, domestic leisure tourism average satisfaction level. The obtained results show the differences between those indicators in NUTS-2 and residence place type level, as well as between summer and winter leisure tourism. The presented results are of particular importance, since some of these differences are significantly large.
