Abstract

The Kolaka Regency has significant mining potential; however, mining activities in this area have environmental impacts, particularly on agricultural land in Pesouha Village. This study examined the effects of acid mine drainage on the soil conditions of agricultural land and its influence on nutrient availability of Pesouha Village, Kolaka Regency. The method included direct observation at the agricultural site in Pesouha Village; the selection of sampling stations based on distance from the irrigation contaminated by acid mine drainage, comprising Station 1, Station 2, Station 3, and Station 4 as a control; assessment of soil conditions and characteristics; and soil sampling at each station for nutrient analysis, including organic carbon, total nitrogen, and the availability of phosphorus and potassium. The results indicated that the agricultural soil has a clay texture and has been contaminated by acid mine drainage, as evidenced by the reddish-brown color of the soil at the three stations, except for Station 4, which exhibited a grayish-black color. Furthermore, rice growth was abnormal, characterized by stunted plants and some leaves displaying pale yellow coloration. The levels of carbon, nitrogen, phosphorus, and potassium were all relatively low at Stations 1, 2, and 3, as well as at Station 4, except for organic carbon, which was optimal at Station 4, following the standards set by the National Standardization Agency (BSN) at the Ministry of Agriculture.

Abstract

This study optimized maize cultivation in Gowa Regency, South Sulawesi, Indonesia, a tropical region with diverse topography and environmental constraints, by integrating Fuzzy Analytical Hierarchy Process (Fuzzy AHP) and spatial autocorrelation analysis to assess land suitability. Using a two-stage Fuzzy AHP, 12 criteria (e.g., slope, landslide risk, rainfall) were normalized via fuzzy membership functions and weighted through expert pairwise comparisons in a GIS framework, with spatial autocorrelation identifying clustering patterns. A 30-meter resolution dataset covering topographic, soil, climatic, land use, and environmental risk factors, prioritized slope, landslide risk, and rainfall, yielding a consistent model (CR = 0.0093). The suitability map classified 1.35% (2,445 ha) as highly suitable (S1), 18.1% (32,868 ha) as moderately suitable (S2), 49.1% as marginally suitable (S3), and 31.45% as unsuitable (N). Spatial autocorrelation (Moran’s I = 0.81, p = 0.001) revealed S1/S2 hotspots in the northern plains, ideal for maize expansion, and N coldspots in the eastern highlands, limited by steep slopes and landslide risks. Overlay analysis highlighted land-use conflicts, with moderately suitable land in settlements and unsuitable land in nature reserves, underscoring the need for integrated planning. The framework prioritizes low-risk S1/S2 hotspots for cultivation, restricts high-risk zones, and promotes sustainable practices like terracing and agroforestry for marginal lands. This replicable methodology offers policymakers and farmers actionable insights to enhance maize productivity while ensuring environmental resilience in tropical landscapes. Policymakers should enforce zoning to protect S1/S2 hotspots and subsidize sustainable practices.

Abstract

Degraded peatlands are natural resources that must be managed properly. The unique characteristics of degraded peatlands, such as high acidity and low availability of macro and micronutrients, are the main challenges in soybean cultivation. The pot experiment was conducted using a completely randomized design consisting of four dolomite dosage levels, namely 0, 3, 6, and 9 t/ha, with five replications. The research objective was to assess the effect of dolomite application on the chemical properties of degraded peatland, physiological characteristics, and soybean yield. The results showed that dolomite application significantly improved the chemical properties of degraded peatlands and increased the physiological characteristics and yield of soybeans. Dolomite at a dose of 6 or 9 t/ha achieved the highest pH, exchangeable Ca, and exchangeable Mg after incubation and after harvest. The highest total chlorophyll and average net assimilation rate were obtained at 9 t/ha dolomite application of 3.95 mg/g and 0.048 g/cm2/day, respectively. The relationship between dolomite and the total chlorophyll content of soybean plants was very strong (r = 0.94) with the equation y = 0.35 + 0.37x. The highest soybean seed weight was observed when dolomite was applied at a dose of 9 t/ha, resulting in 9.72 g/plant, an increase of 219.70% compared to the control. These findings suggest that optimal dolomite application can enhance the fertility of degraded peatlands and improve soybean productivity while supporting the sustainable management and rehabilitation of these ecosystems.

Abstract

Socioeconomic activities and natural environmental changes are the main drivers of land use and land cover (LULC) changes worldwide and this directly affects the amount of soil organic carbon (SOC) stock. Though LULC affects the amount of SOC stocks and fluxes, the mid-lands of Tigray are less studied and represented. In this study, an attempt has been made to determine the effects of LULC change on SOC at watershed scale in the Central Tigray, Northern mid-lands of Ethiopia. Geographically the study area is found in Kola Tembien district, which is about 125 km away from Mekelle, the capital city of Tigray to the west. Five LULC types (cropland, grazing land, forest land, shrub/bush land and settlement) were identified. Nine composite and undisturbed soil samples at a depth of 20 cm and 10 cm respectively were collected randomly from each LULC type. Analysis of LULC change has been undertaken using satellite images of Landsat 5 TM, Landsat 7 ETM+ and Landsat 8 (OLI) with 30 m spatial resolution in ArcGIS10.3 and ERDAS Imagine14. One-way ANOVA was used for SOC analysis among LULC types. The analysis has showed that LULC change was undertaken in Jira watershed during the last 30 years (1987-2017). The highest SOC concentration was observed in forest land and the lowest was observed in cropland in all studied years. The amount of SOC concentration between each LULC types during all study years was significantly different at p < 0.05 except, cropland and grazing land in 1987 and grazing land and shrub/bush land in all study years. Change in LULC has affected the amount of SOC stock in the LULC types. For example, 18.7 t/ha of SOC was gained during the last 30 years due to the conversion of grazing land into forest land. During the thirty years interval (1987-2017) a total of 714.7 ton of SOC stock was gained due to the conversion of the land uses and management interventions. The highest SOC was gained due to the conversion of grazing land in to forest land (2007-2017) which has offered a total of 635.53 ton of SOC. A model was created to predict SOC of similar environments by using the observed SOC and NDVI values of the 2017 LULC types. Finally, the study concluded that the LULC change has affected the amount of SOC stock in the watershed and it is better to increase coverage of forest lands to store more organic carbon in the soil.

Abstract

Open-pit coal mining activities have an impact on environmental changes, one of which is the emergence of acid mine drainage. Acid mine drainage (AMD) arises from sulfide minerals that react with oxygen and water. Coal utilized in electric steam power plants as fuel to produce electrical energy results in combustion residue known as fly ash and bottom ash (FABA). FABA has alkaline properties and has the potential to be combined with plant species that are resistant to acid mine drainage (AMD). This study aimed to explore the potential use of FABA as a growing medium for eucalyptus (Melaleuca cajuputi) to neutralize the pH of acid mine drainage (AMD) in artificial wetlands. FABA block medium was made by mixing FABA, cow manure, and cement as an adhesive and incorporating holes as planting media. The results of this study showed that the application of FABA and cow manure increased the pH of AMD from 3.27 to 6.27 in 24 hours. FABA medium blocks could adsorb heavy metals in AMD, such as Fe in the K1-P1 treatment, from a value of 0.15 mg/L to 0.08 mg/L, and heavy metal Mn in the K3-P3 treatment, from a value of 4.1 mg/L to 0.2 mg/L. In addition, medium blocks K2 (50% FABA + 30% cow manure + 20% cement) and K3 (30% FABA + 50% cow manure + 20% cement) had a good effect on the growth of M. cajuputi seedlings in the K3-P1 treatment with an average height of 17.67 cm and a stem diameter of 9.2 mm for 8 weeks.

Abstract

Zinc is considered an essential mineral, in addition to being a toxic metal that causes serious diseases in humans and animals. Fingerlings of Cyprinus carpio were acquired from a nearby fish hatchery. The experimental fish's morphometric features were noted. All fish were stocked, regardless of gender. The fish were exposed to different concentrations (75, 100, 125, 150, and 175 mg/L) of Zn to obtain the LC50 for 96 hr. The median lethal concentration of Zn was 150 mg/L through 96 hours. As recorded, the fish were exposed to three safe concentrations, 10 mg/L, 30 mg/L and 50 mg/L. The results after 3 and 6 weeks were as follows: When compared to the control groups, all treated groups had significantly higher levels of ALT, AST, and MDA. While catalase was lower than control in some treated groups, GPX results were substantially higher in all treatment groups compared to control groups, and the concentration of MT increased in the treated groups. Glutathione peroxidase (GPX) and metallothionein (MT) gene expression in the blood are markers for metal pollution and abiotic stressors. These changes are trustworthy indications of the cellular and humoral immune responses in Cyprinus carpio. Blood levels of glutathione peroxidase (GPX) and metallothionein (MT) signal exposure to metals and other environmental stresses. These alterations in Cyprinus carpio are reliable markers of the humoral and cellular immune responses.

Abstract

Sustainable agriculture is a crucial solution to address land degradation and food security. This study examined the effects of Chromolaena odorata green manure and botanical pesticides on the chemical properties of degraded Inceptisols, which in turn affect the growth and yield of peanuts. The treatments tested were combinations of four dosages of Chromolaena odorata green manure (0, 10,000, 15,000, and 20,000 kg/ha), and three concentration levels of Chromolaena odorata botanical pesticide (0, 250, and 500 L/ha). Each polybag contained 10 kg of topsoil. The twelve treatments were arranged in a factorial randomized block design with three replications. The results showed that the application of Chromolaena odorata green manure at 20,000 kg/ha significantly improved soil pH, total nitrogen, and C/N ratio, which, in turn, increased leaf area, pod number, and fresh and dry pod weight of the plant. The application of botanical pesticide at 500 L/ha improved leaf area and reduced empty pods of the plant. The combination of green manure and botanical pesticides synergistically boosted soil fertility and peanut productivity. The application of (20,000 kg/ha green manure + 500 L/ha botanical pesticide) yielded the most significant improvements in soil organic C (54.28%), available P (65.11 ppm), and cation exchange capacity (13.10 cmol(+)/kg), along with plant growth and yield. These findings highlight the potential of Chromolaena odorata as an eco-friendly input for sustainable peanut cultivation.

Abstract

This study develops an innovative framework to assess fiscal vulnerability in regions dependent on mining resources in Peru. Using data from 25 departments (2015-2023), this study constructed a multidimensional taxonomy that integrates dependency, volatility, predictability, and temporal trends. The results reveal substantial differences in predictability between resources: Mining License Fees show high predictability (R²=0.953), contrasting with Mining Royalties (R²=0.497). This study identified three distinctive regional profiles where Ancash exhibits the highest fiscal vulnerability (0.723). The practically null correlation (0.02) between dependency and volatility confirms that they are independent and complementary dimensions for assessing fiscal risks. The proposed framework allows the identification of regions requiring priority interventions and offers analytical tools with applicability in similar mining contexts.

Abstract

Exopolysaccharides (EPS) and salt-tolerant, EPS-producing bacteria have attracted increasing attention due to their diverse applications across various fields. This study investigated the characteristics and EPS production potential of Bacillus velezensis DTA1, a salt-tolerant, EPS-producing strain isolated from coral island soil in Vietnam. Strain DTA1 demonstrated notable versatility in utilizing various carbon sources and exhibited a wide tolerance range to temperature, pH, and NaCl concentrations. Response Surface Methodology (RSM) was employed to optimize the culture conditions, resulting in an EPS yield of 32.80 g/L, achieved under optimized conditions of 7.26% sucrose, 3.27% NaCl, and pH 8.46. Through the evaluation of water-holding capacity, this study demonstrated the notable properties of the EPS and culture broth of strain DTA1 in enhancing water retention and soil component aggregation. These findings highlight the potential of strain DTA1 for arid land reclamation applications, particularly in harsh environments such as saline, alkaline, and arid coral sand areas on offshore islands.

Abstract

Coastal regions are highly sought after for human habitation, exhibiting a population density that is threefold greater than the global mean. These zones are pivotal for environmental resources, human prosperity, and economic activities, providing a suite of services. The concept of ecosystem services has garnered international focus for its contribution to sustainable development. These services represent the myriad benefits that ecosystems confer, meeting socio-economic demands and enhancing human welfare. This analysis endeavors to appraise the value of ecosystem services in coastal areas, with a particular emphasis on the physicochemical properties of soils along Djibouti's coastline. It incorporates an assessment of local characteristics, climatic conditions, and the anthropogenic influence on the environment. Despite facing considerable threats to its biodiversity, Djibouti's coastline offers a plethora of vital ecosystem services to its inhabitants. Among the regulatory services rendered by these locales are air quality management, erosion mitigation, soil and sediment retention, climate and microclimate stabilization, carbon storage and sequestration, nutrient recycling, and facilitation of pollination.
