Busk Forestry Enterprise (Ukraine): Historical and Geographical Formation Features and Current State | Chapter 10 | Research Advances in Environment, Geography and Earth Science Vol. 8

 

Our research is based on the processing and territorial interpretation of statistical data from the Busk Forestry Enterprise. Based on these data, we constructed and analyzed maps showing species composition, age structure, and wood stock across different forestry districts. The following characteristic features of the region's forestry were identified: uneven forest cover in the studied area, significant fragmentation of the forest fund in the southern part of the forestry's activity zone, the location of large forested areas in the northwestern part of the forestry, dominance of species such as pine, oak, and alder, slight increase in forest cover in certain areas due to the creation of pine plantations on non-agricultural lands, and the active expansion of black alder forests on waterlogged pastures.

 

The aim of the proposed study is to conduct a geospatial examination of the species composition, age structure, and economic use of the Busk Forestry Enterprise's forest plantations, as well as a retrospective geographical assessment of the forestry territory formation. The practical importance of the research increases in the context of land resource management in newly created communities. The spatial aspects we have developed will also be useful for forestry workers both in the process of consolidating forestry enterprises and in the formation of new forest plantations.

 

The research was conducted using cartographic materials from different periods, allowing us to trace the development of typical forested areas from the late 18th century to the present. We employed the method of temporal cross-sections and a diachronic approach. The study includes fragments of cartographic materials for key areas.

 

We examined the division of the forest fund by categories and established that the largest portion of the Busk Forestry Enterprise's forest fund is occupied by operational forests. Protective forests account for 1.5% of the total forest area in the studied region. Forest availability for the population in the Krasnensky territorial community averages 0.12 hectares per person, while in the Busk community, it is 0.61 hectares per person.

Research on Soil Seed Banks of a Rangeland Area White Nile State, Sudan | Chapter 13 | Cutting-edge Research in Agricultural Sciences Vol. 7

 At the study site, three soil depths (0 to 5, 5 to 10, and 10 to 15 cm) were selected, and the number of live and dead seeds for each were counted in the soil seed bank. The results of the investigation were as follows: In comparison to the lower soil depths (0 to 5 and 5 to 10 cm), the seed bank density was higher in the upper soil depths (0 to 5 and 5 to 10 cm) (10 to 15 cm). The seed density was discovered to be decreasing as the depth was increased. The density of live seeds ranged from 1015 to 5371 seeds/m2, while the density of dead seeds was 3215 to 6957 seeds/m2. Grass species such as Schoenefeldia gracilis, Brachiaria spp., Dactyloctenium aegyptium, and Aristida spp. were the most common, with Schoenefeldia gracilis, Brachiaria spp., Dactyloctenium aegyptium, and Dactyloctenium aegyptium, and Aristida s Panicum turgidum, Euphorbia aegyptiaca, and Cyperus rotundus were among the dominant species to which the dead seeds belonged. The percentage of dead seeds was also higher than that of live seeds, according to the report.

Assessment and Analysis of Pond Fisheries in Climate Change Scenario in the Haor Region of Bangladesh | Chapter 8 | New Ideas Concerning Science and Technology Vol. 5

 Aims: As the monsoon rains taper off, water from the hair recedes, providing fresh nutrient rich lands for seasonal cultivation like aquaculture. Identify the future environmental effects and the effect of climate change on pond fisheries in the haor area and the impact of invasive species through aquaculture on native and natural species.


Study Design: An investigation into the effects of the approach to pond fisheries to decide if the approach is effective with respect to the impacts of climate change on the haor region.

Place and duration of the study: The sites of the study are located for a period of one year in five haor districts in Bangladesh (May 2018 to April 2019) covering the working area of HILIP.

Methodology: The report involves both quantitative and qualitative data collecting and review. 92 sample households in 58 unions of 28 upazilas (sub-districts) in five project districts were chosen randomly for a quantitative analysis. Fish capture data was collected from perennial and seasonal ponds, including information on species composition, development and sales. This paper used qualitative primary data gathered through in-depth interviews, main informant interviews, and focus group discussions.

Results: In perennial ponds, fish production was found to be greater, but not significantly higher than that in seasonal ponds. Biodiversity in seasonal ponds, however, has been found to be higher and greater than that in perennial ponds. The results clearly support the observation that pond fish culture is an attractive activity for haor individuals, especially those who can operate both perennial and seasonal ponds and handle minimum feeding requirements, sustain them, and effectively market the outputs. The present study fills gaps in established knowledge of the diffusion of fish pond culture in Bangladesh's haor area.

Conclusions: pond fisheries tend to perform better, so that the development of aquaculture will offset some of the lost catch fisheries in Bangladesh's haor region. Established cultural practices could encourage innovation and learning in the field of haor under future initiatives. In the haor field, pond fishery mainly has an income-generating aspect and is less likely to be affected by the impacts of climate change. Future programs, however, should prioritize the farming of fish with the ability to balance the ecosystem of haor. The approach should be applied beyond the areas of research and implemented as a key strategy for the production of Bangladesh's hair fisheries resources.
