The comparative analysis of conservation management of Simien Mountains National Park (SMNP) and Qianjiangyuan National Park (QNP) in China provides deductions that can be successfully implemented as conservation strategies and replicated in other protected areas. QNP benefits from a tiered administrative framework with strong provincial leadership and stakeholder collaboration yielding versatile conservation strategies. Effective land-use regulations and zoning have kept more than 81.7% of the ...

As of 2005, the city of Saidia has undergone substantial urban expansion, which has led to the Tazgrarte Forest, a major urban green space, not just for the citizens but also for tourists alike, to decline in urban forests. In this regard, this research aims to assess the differences in the forest cover of Tazgrarte Forest from the period of 2005-2025, concentrating on the impact of urban expansion at three critical points in time: 2005, 2015 and 2025. Forested area reduction and urban growth dy...

Shanxi Province, a leading coal-producing region in northern China, holds abundant reserves of bituminous and subbituminous coal critical to the nation’s energy sector. However, extensive coal mining has left behind Goaf areas underground voids and fractured zones that pose serious safety hazards and environmental risks. These challenges require innovative approaches to ensure sustainable resource management and ecological protection. This work aims to enhance the exploration and management of G...

Pore structure determines the reservoir capacity and permeability, which is the key content of unconventional oil and gas exploration and development research. In this study, a series of analysis methods, such as casting thin sections, scanning electron microscope, X-ray diffraction and high-pressure mercury injection, are used to study the petrological characteristics, physical characteristics and micro-pore structure of the Chang 6 reservoir in the Wuqi area. Based on a clear comprehension of ...

Fluoride, whose levels are higher than the World Health Organization (WHO) recommended level of 1.5 mg/l, results in health issues. Therefore, fluoride contamination is a matter that calls for concern by all people and governments, especially in countries where volcanicity has been experienced. This study sought to model spatial variation, distribution, and prediction of fluoride levels in groundwater in the river Njoro catchment. This study aimed to observe the levels of fluoride and give recom...

Extensive research has been undertaken to model the petroleum system of the Maui Field within the Taranaki Basin, New Zealand. Nevertheless, there are persistent uncertainties surrounding its intricate petroleum system, the processes of hydrocarbon generation, and migration. Despite its status as New Zealand’s largest petroleum producer, the historical account of hydrocarbon formation, migration, and charging in this field remains largely enigmatic. This systematic literature review offers a com...

The physico-chemical characterization of the Nangongo peat bog in South Kivu province, Democratic Republic of Congo (DRC), was conducted in this study. The results show that the characteristics of this peat bog are like those of other peat bogs presented in the literature. The Nangongo peat bog belongs to the ombrotrophic peat bog category. The physical and chemical characteristics of the samples analyzed showed a generally low ash content compared with the volatile matter content, and a deficie...

Sedimentary environments are an important part of paleogeography and sedimentology, and there is a long history of using geochemical and mineralogical methods to analyze palaeoenvironmental problems using sedimentary rocks as a research vehicle. By summarizing the important results of previous work on tracing the palaeoenvironment using the composition and distribution characteristics of the macronutrients and trace elements as well as the characteristics of mineral composition, we aim to sort o...

In this paper, we analyzed the characteristics of fossil legume pods from the “Committee Creek” formation of the Teater Road, John Day Formation in Crook County, Oregon, in western North America. 23 fossil specimens were collected and compared with the existing genera of the family through detailed observation of the legume pods. A total of three genera and four species of nearest relatives were identified as extant, and four undetermined species were studied. These include the similar species o...

Based on the coring data of 48 wells and the logging data of 213 wells, this paper comprehensively analyzes the shallow water delta sedimentation and sand body stacking characteristics of the Yanchang 6 1-6 2 sub-member of the Triassic in the Zichang area of northern Shaanxi, as well as the corresponding relationship with reservoir physical properties. According to the accommodation space and sediment supply flux, the single sand bodies in the study area are distributed in an...
