The agricultural sector is a source of greenhouse gas emissions that directly affect the global problem of climate change and contribute approximately 11% in total greenhouse gas emissions in the world and in Croatia too. Irregular and irresponsible agricultural practices, such as excessive tillage and improper fertilization often lead to soil carbon loss and increased carbon dioxide emissions to the atmosphere. This field study provides results how agricultural practices affect carbon dioxide emissions from soil, carbon sequestration and soil quality during the cultivation of winter wheat. The field experiment was conducted in a temperate continental climate on distric Stagnosol. Four investigated treatments were: organic fertilization, mineral fertilization, control treatment and black fallow. The lowest carbon dioxide emission was recorded on bare soil and the highest on organic fertilization treatment. The application of manure, mineral fertilizers and calcification rendered significant effect on some soil chemical characteristics and daily carbon dioxide flux.

Few works have been carried out on the coupled impacts of different management practices and tractor traffic on soil properties and degradation in vineyards, grape productivity and must quality. The influence of different tillage practices (conventional tillage—CT; grass coverage in a given year—INV‐GC; tillage in a given year—INV‐T) and continuous grass coverage (CGC) on bulk density (BD), soil water content (SWC), CO2 emissions, grape yield and must quality have been investigated in a vineyard in Zagreb, Croatia. During 2017, soil properties were analysed in the 0–10 cm and 10–20 cm layers after 3, 6 and 11 tractor traffic passes. The results showed that tractor traffic increased the BD in the CGC, INV‐GC and INV‐T treatments. The BD at the 0–10 cm and 10–20 cm depths was significantly higher in CGC than in CT. During the wet year of 2017, CT and INV‐T had significantly higher SWCs than did CGC and INV‐GC. The CO2 emissions under different management practices were INV‐T (120.3 CO2 ha−1 yr−1) > CGC (111.4 CO2 ha−1 yr−1) > INV‐GC (71.7 CO2 ha−1 yr−1) > CT (51.5 kg CO2 ha−1 yr−1). The effects of soil management on must quality and grape composition measurements were also detected. Grape yield was as follows: CT (5.37 kg vine−1) > INV‐GC (4.43 kg vine−1) > CGC (4.06 kg vine−1) > INV‐T (3.87 kg vine−1). Treatments had a significant impact only on pruning weight, pH value and free amino nitrogen (FAN), whereas no significant differences were found in the cluster number per vine, mean cluster weight, sugar content and titratable acids.

This research focuses on analyzing residents' perception and attitude toward tourism development in the Federation of Bosnia and Herzegovina (FB&H). For the purpose of this research, the existing models on residents' perception and attitudes were modified and a new theoretical model of six constructs was tested applying Confirmatory Factor Analysis (CFA). The dimensions of the model, perception of tourism management, perception of economic, social and environmental impacts, residents' satisfaction, support for further tourism development, were formed as latent variables, accompanied with a set of three or four consonant questions. The model suggests that the support for tourism development is indirectly stipulated by the perception of tourism management, and by economic, social and environmental impacts. Analyses have shown that 6 out of the 7 suggested hypotheses have been confirmed. The findings indicate that the residents of the FB&H strongly support tourism development as they perceive it brings more positive impacts, which are greater than the actual governmental investment into the sector.
