Abstract

 This paper considers the issue of mining non-metallic (rock) products in the context of transition economies. Our studies have shown that interest in non-metallic products is growing every year, as evidenced by the growing volumes of production both around the world and in the group of countries considered in the article. The market analysis for non-metallic minerals has revealed the market development dynamics; however, its high monopolization may lead to some restrictions on free competition in subsoil use. In order to assess such monopolization, we have calculated the Herfindahl-Hirschman index for each non-metallic mineral mined in countries with economies in transition. We have found that the entire product range under consideration is part of a highly concentrated market dominated by the Russian Federation. We have presented some options for designing and introducing various kinds of arrangements to develop the mining potential of non-metallic minerals in order to reduce the dominant component of individual countries or companies and to balance the market. It is proposed to consider a partial transition from the possibility of developing deposits to an underground one — as an alternative option that harms the environmental load on the situation in the mining area. The results of this study will be used to conduct a detailed analysis in each country under review, which will provide the most complete picture of the mining industry in countries with economies in transition.

Abstract

The utilization of natural resources in recent decades is not accompanied by proper and effective management. This has a major impact on environmental degradation in watershed scale and climate change. The study aimed to evaluate changes in soil characteristics at various ages of sand mining and the cost of reclamation of environmental degradation due to sand mining activities. The study was conducted in Sumberbulu Micro Watershed, which is located in Wajak Sub-District, Malang Regency. Soil sampling was collected from un-mined, 2 to 6 years old sand mining and post-mining lands. Natural resource equivalency analysis (REA) was applied for environmental damage assessment and reclamation cost calculation required to restore natural resource services to their original condition. The findings show that sand mining activities significantly decreased soil organic C in 0-40 cm soil depth, resulting in increased soil bulk density and decreased soil porosity at 20-40 cm depth of soil. Sand mining activities by using truck traffic carrying mining products, soil erosion, and the removal of topsoil during mining activities determined changes in soil properties. REA shows that the total area of land that must be reclaimed is 21,487 ha. The land will be reclaimed by revegetation (with maize) to restore the lost function of environmental services and income of local farmers, assuming a reclamation cost of 36,767,500 IDR/ha. Therefore, post-mining land reclamation should be encouraged by the government for mining business actors in Indonesia so that the land can be reused as before.

Abstract

The growing needs of mankind for minerals predetermine a systematic increase in the scope of mining operations. However, it is known that mineral resources are not evenly distributed in the bowels of the earth; therefore, due to their production, some regions of our planet can significantly outstrip other regions in their technical and, as a result, economic development; hence, the constant need to extract more minerals in order to develop the domestic industry and to strengthen the economy. This paper is devoted to the Central Asian states, their internal structure, economic integration into the world economy, and the mining sector development as the basis of a successful model for the development of the country as a whole. The study summarizes and analyzes the political system and socio-economic conditions in the Central Asian states. It presents a brief overview of the scale of mining operations; provides information about the mining industry structure in each country and the proceeds from its sales. Taking the Central Asian states as an example, we demonstrate the importance of the mining sector as an integral part of a country’s domestic economic structure.

Abstract

This paper focuses on the outbreak of illegal mining (galamsey) operations in Ghana in recent times claiming that the outbreak is accompanied by massive environmental destruction including pollution of water bodies, degradation of farmlands and forest landscapes. Despite the efforts of governmental, non-governmental and civil society organisations to streamline the artisanal and small-scale (ASM) sector since 2017, illegal mining activities remain a livelihood strategy for several Ghanaians. Institutions, politics and local manoeuvrings have rejuvenated and shaped by illegal mining activities. This study employs the narrative review approach to theorize and analyse the pertinent issues influencing the outbreak of ASM activities in Ghana. We draw on the extant theoretical and empirical perspectives to argue that illegal mining activities persist in Ghana today because every stakeholder wants to be a winner–the state institutions are weakened by politics for political triumphs. The local authorities collaborate and embrace illegal mining activities for economic gains while the local communities perceived illegal mining as a last resort to circumventing dispossession by state institutions and foreign mining conglomerates of their share of the mineral wealth. We posited that until the local communities’ share of mineral wealth is duly served them including desirable compensation regimes, illegal mining activities would continue to flourish in Ghana. It is therefore, suggested that mineral resource decisions in the country must identify and incorporate the needs of the local communities. Further research into the needs of local communities, expectations and challenges regarding mineral resources extraction within their range is pertinent.

Abstract

Amending Ultisols using organic matter encourages a paramount improvement in its chemistry and fertility characteristics. This study was aimed to evaluate the changes in soil chemical properties due to the animal manure amelioration in Ultisol in the Jasinga, Bogor, West Java, using classical and advanced statistical methods. Composite soil samples were collected then incubated with three types of animal manure (cow, chicken, and goat) and four rate levels (0, 2.5, 5, and 7.5% of dry weight). The dynamics of eleven soil variables (pH, organic C, total N, cation exchange complex/CEC, base saturation/BS, and exchangeable Al, H, Ca, Mg, K, and Na) were observed four times (0, 2, 4, and 6 weeks). Basic cation saturation ratio/BCSR and sufficiency level of available nutrients/SLAN soil fertility approaches were applied. Modeling comparison was done among multiple linear regression/MLR, machine learning/ML (tree regression/TR, random forest/RF, gradient boosting machine/GBM), and deep learning/DL (multilayer perceptron/MLP). Most of the soil chemical and fertility parameters exhibited strong relation among three applied factors. Generally, their values failed to reach the BCSR’s ideal soil and national SLAN’s sufficiency criteria; oppositely, they were categorized as sufficient based on the global SLAN approach. Multivariate analysis revealed the similarity among manure type and rate, whereas incubation time showed the opposite trend. MLR usage was convenient in modeling BS, pH H2O, and Al saturation. Meanwhile, CEC modeling requires more sophisticated methods. This study highlighted the possible improvement of Ultisol chemical properties and fertility characteristics by amending it with a higher rate and low C/N ratio of animal manure, and using ML to capture non-linear relationships in soil.

Abstract

Since Inceptisols, in general, contain low soil organic matter and major plant nutrients, inorganic fertilizers are commonly added during corn cultivation. In order to maintain long-term soil health and fertility, bioferilizer and organic ameliorant application are suggested. The addition of nitrogen (N)-fixing bacteria (NFB) can benefit plant growth through the supply of available nitrogen for plant uptake. Organic ameliorants can enhance soil chemical and biological properties. A field trial had been performed to observe the effect of biofertilizer and organic ameliorant on corn growth, N status in soil and plant, and the yield and wasteof corn. The experiment was designed in a Completely Randomized Block Design that consisted of four treatments and six replications. The treatments were 1.2 kg/ha N-fixing mixed biofertilizer, 2 t/ha organic ameliorant, and mixtures of biofertilizer and ameliorant. Control plants received neither biofertilizer nor ameliorant. The experiment results found that N-fixing biofertilizer and ameliorant increased plant height, fully-developed leaves number, soil reaction and N uptake of corn compared to the control. The total-N content was slightly increased after NFB inoculation with and without amelioration over other treatments. Plots treated with biofertilizer and ameliorant produced a higher grain weight compared to the control treatment. Corn wastes such as empty corn cob and husk weight were increased in plants treated with biofertilizer, ameliorant and a combination of both. This study suggested that the combined application of biofertilizer and ameliorant produced 66% more grain yield and 84 % more cob and husk waste compared to untreated plants.

Abstract

Groundwater quality assessment study was conducted in Wera Dijo, Southern Ethiopia. The study's objective is to understand water chemistry suitability for domestic and irrigation activities. In the study area, only regional hydrochemistry work has been done; hence this study focused on the detailed water chemistry of the study area. Twenty-eight shallow and deep water samples were collected, and major physical and chemical parameters were studied. The important hydrochemical facies of water present throughout this region are Ca–Mg–HCO3, Ca–Mg–SO4 and Na–HCO3–Cl. Except for fluoride, sodium, and potassium ion, the levels of major cation and anion were found to be below the World Health Organization's allowable limits for drinking purposes in the majority of the study area. The fluoride ion in groundwater exceeded the highest allowable amount of 1.5 mg/L for drinking water in fifteen of the samples. The sodium percentage, permeability index, sodium absorption ratio and The United States Salinity Laboratory (USSL) categorization were used to evaluate the water in this study location for irrigation purposes. Based on several water quality parameters overall, the research area water chemistry was suitable for drinking, agricultural activity and industrial use.

Abstract

The presence of groundwater in the groundwater basin increases the potential of rainwater seeping into the soil and reaching the groundwater system. As a result, the soil takes longer to get saturation and maintain its stability. The groundwater basin stability is also influenced by the layer's lithological, soil, and morphological properties above the groundwater system and human activities on the land. The purpose of this study was to characterize the groundwater basins, non-groundwater basins, and landslides that happened in those locations in the tropical region of Bogor, Indonesia. The characteristics of landslide events, including lithological, groundwater table, soil, slope, and land use in each groundwater basin zone, were evaluated using quantitative descriptive analysis. The result showed 686 landslides from 2015 to 2019 that mainly occurred in the discharge zone, characterized by slope classes of >45%, soil types of Technosol (Inceptisols), Quaternary lithology periods, and settlement land use. The landslide type in the groundwater basin is dominated by surface landslides, while the landslides in the non-groundwater basin are mostly shallow landslide types.

Abstract

This study was conducted in El-Abyar area in El-Jabal El-Akhdar region, northeast Libya. The aim was to study the environmental settings and the potential and possibility of establishing a protected area in this important region from a historical, biological, social, and economic point of view. The methodology included an intensive literature review, distribution of 300 questionnaires, soil and water analysis, fauna and flora survey, in addition to extensive field observation during the period from 2011 to 2021. The study highlighted the significant representative state of the study area for the whole El-Jabal El-Akhdar region in terms of environmental conditions and inappropriate anthropogenic pressure. Although the area has been severely degraded due to the arid climate coupled with decades of mismanagement, it still has remarkable ecological and environmental features and there is a feasible possibility of being converted into an effective protected area for biodiversity conservation with sustainable use of its natural resources by the local population (Category VI on the International Union for Conservation of Nature Classification for protected areas). The remaining barriers for which drastic solutions need to be implemented are a lack of awareness, a lack of protected areas guidelines and national perspectives, interest conflict with local people, a lack of constant funding, and failure of legislation enforcement.

Abstract

Chromium pollutants in textile wastewater can be removed by bioremediation using sulfate-reducing bacteria (SRB) from forested wetland soil. Biostimulation of carbon sources in the form of molasses and a supporting material in the form of zeolite to trap bacteria and create biofilms can improve the ability of SRB to bioremediate chromium. The batch bioremediation technique was further examined by including molasses, a combination of molasses and zeolite, and SRB, which has been adapted to acclimatize wastewater that is diluted two times. Adaptive SRB aged 7 days, which had reached the exponential growth phase, showed optimal bioremediation activity when molasses and zeolite were added. Results of further observations of the consortium on continuous bioremediation with the same treatment showed decontamination of chromium efficiency that reached about 94%. In addition, pH values decreased efficiency at approximately 7.3 in 14 days of incubation. The biological oxygen demand, chemical oxygen demand, and sulfate concentrations also decreased at around 89%, 92%, and 91%, respectively. SRB immobilization with zeolite-induced biofilm formation was observed at 9 days, and it further increased at 14 days. SRB cells observed were attached to the surface of the zeolite, between cells connected to each other by extracellular polymeric substances. The mass of sulfur and chromium on the surface of the zeolite increased from the 9th and 14th days. Sulfur increased from 0.07% to 0.27%, whereas chromium increased from 0.21% to 0.84%. The increase in the percentage of the two elements on the zeolite surface indicated the decontamination of sulfate and chromium pollutants in wastewater.
