Abstract

This study assessed urban growth in Kaduna using remote sensing indices, landscape metrics, and Landsat images (2003, 2013, and 2023). Land use/land cover was carried out using the decision tree algorithm, while the transition matrix was computed using ArcGIS 10.8. Landscape fragmentation was assessed using Fragstat 4.3. The results revealed that between 2003 and 2023, bare land, built-up areas, and water bodies increased by 596 km2, 121.04 km2, and 0.22 km2, respectively, while cultivated land and tree cover decreased by 525.54 km2 and 191.91 km2, respectively. For the rate of change, bare lands,   built-up areas, and water bodies increased by 29.81 km2, 6.05 km2, and 0.01 km2 annually, respectively, while cultivated lands and water bodies decreased by 26.28 km2 and 9.60 km2, respectively. For the land-use transition, 112.71 km2 of the built-up areas remained persistent. Cultivated lands, tree cover, and water bodies transitioned to built-up areas, losing 85.43 km2, 13.91 km2, and  0.91 km2, respectively. Landscape fragmentation analysis revealed that the number of patches increased from 405 in 2003 to 614 in 2023. Patch density, largest patch index, total edge, edge density, area-weighted mean shape index, and fractal dimension index decreased between 2003 and 2013 but increased between 2013 and 2023, indicating urban sprawl. However, the area-weighted mean contiguity index consistently increased between 2003 and 2023. The study concluded that urbanization is the leading driver of landscape fragmentation. This study recommends that development should be controlled to reduce encroachment on agricultural lands and habitats, thereby reducing landscape fragmentation and land degradation.

Abstract

Nickel (Ni) is considered a toxic heavy metal that causes serious diseases in humans and animals. Therefore, this study was conducted on common carp, which is considered an essential food item for humans. This study was designed to investigate the effect of nickel on the hepatic and antioxidant enzymes of Cyprinus carpio after 3 and 6 weeks of exposure to water contaminated with Ni. C. carpio fingerlings were purchased from a neighboring fish hatchery. The morphometric characteristics of the experimental fish were documented. All fish were stocked, regardless of gender. The fish were exposed to different concentrations (20, 40, 60, 80, and 100 mg/L) to obtain the LC50 for Ni during 96 hours, and the median lethal concentration of Ni was 80 mg/L through 96 hours. The fish were exposed to two safe concentrations, 1 ppm and 5 ppm. The results after 3 and 6 weeks were as follows: When compared to the control groups, all treated groups had significantly higher levels of liver function parameters (ALT and AST). Malondialdehyde (MDA) and catalase activity measurement (CAT) enzyme levels were considerably higher in all treated groups after 3 and 6 weeks as compared to control groups. These changes are trustworthy indications of the cellular and humoral immune responses in C. carpio.

Abstract

On December 14, 2021, an earthquake with a magnitude of 7.4 originated from the Flores Sea, impacting Kalaotoa Island in Indonesia, resulting in significant structural damage. Macroseismic observations at the site classified that there were 120 buildings slightly damaged, 108 buildings moderately damaged, and 201 buildings heavily damaged. The shakemap shows that Kalaotoa Island experienced VI-VII MMI shaking. The results of the field survey showed many indications of subsidence as many fractures were found in Kalaotoa Island. This study employed Differential Interferometry Synthetic Aperture Radar (DInSAR) to quantify land subsidence and uplift in Kalaotoa Island before and after the earthquake. Sentinel-1A satellite radar data from December 2 and December 14, 2021, were analyzed. The results revealed subsidence of up to 12 cm in Garaupa Raya Village and uplift of up to ±10 cm in Lembang Mate’ne Village. Approximately 50.50% of Kalaotoa Island experienced subsidence (39.4 km²), primarily in Garaupa Village (18.85 km²), while 49.02% of the island experienced uplift (38.2 km²), mostly in Lembang Mate’ne Village (19.03 km²). This spatial analysis underscores the efficacy of DInSAR in detecting and mapping surface deformation, offering critical insights for earthquake preparedness, mitigation efforts for impacted landscape topography, stability soils, structure of ecosystems, and infrastructure resilience.

Abstract

The quality of acidic soil is determined by organic C content produced from rice straw biochar in agriculture. In this context, liquid extract from Kappapychus alvarezii (K-sap) is used as a biochar enrichment agent. Therefore, this research aimed to (i) analyze the character of K-sap enriched rice straw biochar with different volumes, as well as (ii) evaluate the impact on soil water holding capacity, size class distribution, aggregate stability index, respiration rate, and acidic soil chemical characters. The treatment tested was the volume of K-sap kg-1 biochar, namely (i) without biochar, (ii) 0 mL, (iii) 500 mL, (iv) 1,000 mL, and (v) 1,500 mL. Each treatment was repeated three times and placed according to a randomized block design procedure. The area covered by K-sap, pore size, and amorphous degree increased while the pore volume of the biochar surface decreased. The addition of 1,000 mL of K-sap kg-1 biochar released a new peak number associated with the aliphatic and aromatic groups. The K-sap enriched biochar increased the proportion of soil aggregate size of 1-2 mm, water holding capacity, carbon storage, pH, total N, available P and K, exchangeable base cations as well as base saturation. Meanwhile, the concentration of Al3+ and H+ were decreased in the acidic soil solution. The results showed that the performance of rice straw biochar, K-sap volumes, soil chemical quality, water holding capacity, and ability to store carbon of the acidic soil was improved by adding K-sap volume.

Abstract

The study aimed to determine the effect of biochar on the growth and yield of several rice varieties in a tidal wetland agroecosystem. This research used a split-plot design with the main plot was biochar application, consisting of three levels (no biochar, rice husk biochar, and coconut shell biochar), and the subplot was rice variety consisting of ten varieties (Inpara, Inpari 30, Kuning, Karya Rendah, Bujang Pelawah, Pandan Wangi, Bujang Berinai, Kwatek Tinggi, Candu, and Serai). Plant parameters observed were plant height, number of tillers, productive tillers, panicle length, number of grains per panicle, number of empty grains per panicle, milled rice weight, and weight of 1,000 grains. Results of this study showed that the application of biochar improved soil fertility by increasing organic carbon, available phosphorus and potassium, cation exchange capacity, and reducing the soluble iron in the soil. However, the application of biochar did not significantly affect the height of rice plants. The application of coconut shell biochar yielded the best results in increasing the number of productive tillers, the number of grains per panicle, grain dry weight, and reducing the number of empty grains per panicle.

Abstract

The article presents unique research conducted in Bidoup-Nui Ba National Park, Vietnam, focusing on the biogeochemical element migration in soil and plants. The study aimed to identify element content changes, biological accumulation, and biogeochemical mobility during wet and dry seasons across different landscape conditions. The research revealed the active elements involved in migration and accumulation, assessed mobility and accumulation in bamboo organs, and highlighted the peculiarities within the "soil-plant" system. The study found that the uptake of certain microelements by plants is influenced by landscape facies and moisture conditions. For example, Zn, Cu, and Co were introduced through plant litter during the wet season and accumulated, while Mo accumulation was more pronounced in the dry season. Furthermore, the research observed variations in biological uptake by bamboo organs, with different landscape conditions and seasons playing a role. The biogeochemical mobility of elements in bamboo organs increased significantly with soil moisture during the wet season. Overall, the research provided insights into element accumulation and biogeochemical migration. Notably, the accumulation of element B was found to increase with soil moisture, while its reduction was associated with slope process activation during the wet season.

Abstract

Diesel fuel pollutants contain toxic hydrocarbons dominated by aliphatic and aromatic hydrocarbons. Hydrocarbon pollutants can be degraded in an environmentally friendly manner through bioremediation using hydrocarbonoclastic bacteria, i.e., Pseudomonas aeruginosa B031, which harbors the alkB gene that encodes an alkane hydroxylase that degrades alkane chains in hydrocarbons. This study compared the ability and efficiency of P. aeruginosa B031 to degrade diesel pollutants in a batch system and a continuous system using a column bioreactor, as well as the expression of alkB. P. aeruginosa B031 could more efficiently degrade diesel fuel in a continuous system in a column bioreactor than in the batch system. The concentrations of phenol, total organic carbon, chemical oxygen demand, and biological oxygen demand in the column bioreactor underwent a greater decrease than those in the batch system, namely 1.5-fold, 1.7-fold, 1.4-fold, and 1.3-fold, respectively. The decrease in these concentrations was followed by changes in functional groups, as shown via Fourier transform infrared spectroscopy. The number of bacteria and the concentration of exopolysaccharide increased in the column bioreactor by 4-fold and 2.3-fold more than the increase in the batch system. The ability of P. aeruginosa B031 to degrade diesel fuel in the column bioreactor was also demonstrated by the higher expression of alkB than that in the control.

Abstract

This research aimed to determine the effectiveness of several types of liquid organic fertilizer (LOF) derived from plant waste and the dose of P fertilizer on the growth and yield of upland rice on degraded acid soil. The treatments consisted of two factors. The first factor (A) was several types of LOF consisting of A1 (control), A2 (LOF containing isolates of P-solubilizing bacteria), A3 (LOF-banana waste), and A4 (A2+A3). The second factor (B) was fertilizer doses consisting of B1 (50% of the recommended dose of P fertilizer), B2 (75% of the recommended dose of P fertilizer), and B3 (100% of the recommended dose of P fertilizer). The treatment combinations were arranged in a factorial randomized block design with three replications. The research results showed that applying either LOF-banana waste or the mixture of LOF-banana waste and LOF-containing isolates of P-solubilizing bacteria improved plant height, the number of tillers, and N and P uptake by the plant. The rice grain yields among the treatments were not significantly different, but the highest rice grain yield (139.8 g/pot) was obtained at the treatment of the mixture of LOF-P isolate + LOF-banana waste (A2+A3 treatments). The 75% of the recommended dose of P fertilizer was not significantly different from 100% P fertilizer with LOF on growth and yield upland rice and nutrient uptake by the plant.

Abstract

Land degradation in Ethiopia is a pressing issue that demands immediate attention. Although various sustainable land management options have been introduced through top-down approaches, farmers have shown low adoption rates. The objective of this research was to assess the community prioritization of landscape restoration technologies and the appropriation of ecosystem services in the Basona-Worena and Doyo-Gena woredas of Ethiopia. The evaluation of land management option tool was used to survey farmers' preferences and compare different land management options based on input, cost, perceived advantages, and potential drawbacks.Data from 64 participants revealed that farmers were interested in a wide range of benefits. However, their top three preferences were increased food supply, enhanced soil fertility, and improved water supply. The study emphasized the need for site-specific land management measures. Farmers in Basona-Worena favored terrace and bund practices, while farmers in Doyo-Gena preferred exclosure and agroforestry practices. Conversely, the propensity of terracing to attract rodents and pests, the lengthy time takes to see results from bunding, and the cost of gabions were among the shortcomings that farmers identify in conservation techniques. Terracing was the first option for supplying fundamental ecosystem services in both locations, followed by biological measures, water percolation pits, and bunds. All farmers ranked the business-as-usual option as their least preferred option because they perceived it to have limited potential for yielding desired benefits. These findings provide a robust model for informed decision-making on suitable restoration technologies, holding promise for landscape restoration initiatives in Ethiopia and similar locations worldwide.

Abstract

Bantul Regency, located on Java Island, is one of the areas in Indonesia with abundant groundwater sources, thus experiencing rapid urban growth. The hazard of groundwater vulnerability in this area has increased due to urban expansion that coevals with changes in land use and human population growth. The objective of this study was to analyze how groundwater vulnerability has changed due to land use conditions and what impact those changes have had. Because of the various variables associated with urban growth, the sub-districts of Bantul and Bambanglipuro were explicitly chosen as research areas. This study compared groundwater vulnerability and land use between 2009 and 2021 in a spatiotemporal manner. The vulnerability determination method used is the Susceptibility Index (SI), which consists of the parameters depth of groundwater table, groundwater recharge, aquifer media, topography, and land use. Each parameter is processed into an index of groundwater vulnerability by scoring and weighting methods. Techniques for descriptive comparative analysis are employed to ascertain how changes in land use will affect the degree of groundwater vulnerability. The results of the land use classification show that the agroforestry area has decreased while the semi-urban area has increased in 2009 and 2021. The sub-district of Bambanglipuro underwent numerous changes. On the other hand, it is known that medium and high vulnerability levels dominate groundwater vulnerability. In this instance, it is concluded that variations in land use have impacted how groundwater vulnerability levels are distributed.
