The expansion of the restoration efforts can be monitored using satellite images to track the progress of operations by observing changes in land cover area. Community forest certification also can enhance the success of land restoration endeavours. Therefore, this study aimed to show the change in forest land cover and the amount of carbon stored from 1972 to 2021. Landsat imagery was used to depict land cover conditions in 1972, 1982, 1993, 2000, 2008, 2014, and 2021, before and after the implementation of restoration and community forest certification programs. The Normalized Difference Vegetation Index approach was employed for satellite images captured in 1972 and 1982, while the Forest Canopy Density method was employed for images in 1993, 2000, 2008, 2014, and 2021, to illustrate the progressive increase in wono land cover. Meanwhile, carbon storage was analysed from 1972 to 2021 using national carbon storage conversion. The results indicated that restoration activity and the establishment of community forest certification increased wono area and carbon storage, which totalled 55.90 ha and 5,499.04 t C between 1972 and 2021. Augmenting carbon storage within wono land cover constituted an effective strategy for mitigating climate change.","PeriodicalId":36513,"journal":{"name":"Journal of Degraded and Mining Lands Management","volume":"77 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139126163","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The research was carried out in the tailings area of Mile 21.5 Timika from March to September 2022. The research aimed to study the dosage levels of Pistia stratiotes composts as an ameliorant to support the growth and yield of chili cultivated in the fresh tailings area. This study was laid out in a randomized block design with the Pistia stratiotes compost as a treatment, which consisted of PS1 = 1 kg/plant, PS2 = 2 kg/plant, PS3 = 3 kg/plant, and PS4 = 4 kg/plant in 6 replications. Based on the results, there was a significant effect of Pistia stratiotes compost on the growth and yields of chili. PS4 treatment produced the highest growth (plant height and leaf number) and highest yields (fruit number/plant, fruit weight/plant, fruit weight/plot, fruit weight/ha), while PS1 produced the lowest growth and yields. Chili produced 4.19 t/ha by PS4, indicating a high yield potential when tailings turned into a more stable growth media over time. There was a significant correlation between plant height and leaf number with the fruit weight. This shows that the vegetative growth component is closely related to increased chili yields. The high heritability value indicates the genetic factor influenced the growth and yields of chili more than the environmental factors. The metal contents in the chili fruit tissue are below the threshold level. The findings of this study emphasized the appropriate reclamation approaches using Pistia stratiotes compost as an ameliorant, which effectively improves the quality of tailing as growing media to maximize chili yields.","PeriodicalId":36513,"journal":{"name":"Journal of Degraded and Mining Lands Management","volume":"34 7","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139125723","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Poor management practises regarding peatlands can lead to land degradation, and peatland degradation typically has negative effects. Recent tropical peatland research in Indonesia has predominantly revolved around the examination of the ecological consequences resulting from various management approaches. There is little study on farmers' agroforestry efforts to preserve and restore degraded peatlands. A comprehensive examination was undertaken to assess a range of facts, information, and scholarly articles pertaining to the practise of agroforestry on peatlands in Indonesia. The primary incentive for farmers to adopt agroforestry systems originates from their recognition of the impending scarcity of trees. By integrating intercrops with cultivated trees, farmers anticipate generating adequate money to fulfil their family's economic requirements. Farmers who choose intensive intercropping practises are motivated by market demand, whereas farmers who do not adopt this approach tend to favour crops that necessitate less rigorous management. The provision of governmental assistance holds significant importance, and there is a pressing need for additional guidance and support. The potential for rehabilitating degraded peatlands by the implementation of agroforestry practises of native tree species is considerable. Their growth patterns contribute to enhanced vegetative coverage, resulting in heightened moisture levels, reduced temperatures, diminished fire hazards, and improved peat soil quality. The relationship between the physiography of the land and the depth of the peat is directly associated with the patterns and components of agroforestry in peatland environments.","PeriodicalId":36513,"journal":{"name":"Journal of Degraded and Mining Lands Management","volume":"86 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139128763","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study found that the soil microbiological and physicochemical properties varied widely. Dominant lignocellulolytic bacterial population and their cellulase enzyme activity were higher than fungi, regardless of sampling depth and management zone. PCA and GLMM analyses showed the significant importance of sampling depth and management zone in governing lignocellulolytic microbial population, their enzyme activities, and Rh. Microbial population and cellulase activity were also remarkably affected by the interaction of all studied factors. Peat chemical properties (pH and total Mn) controlled the natural variance of lignocellulolytic microbes and their enzymes, whereas total K regulate Rh.

In this study, remote sensing and geographic information system (GIS) techniques were employed to track LULC changes in the study area from 1992 to 2022. The supervised classification method in ArcGIS 10.8 software was applied to Landsat satellite data (Landsat 5-TM for 1992 and 2010, and Landsat 9-OLI/TIRS for 2022) to detect and classify five main LULC classes: agricultural land, barren land, vegetation, built-up, and waterbodies. The accuracy of the classification was assessed using kappa coefficients, which were found to be 0.882, 0.891, and 0.915 for the years 1992, 2010, and 2022, respectively. During the period 1992-2022, the areas of agricultural land, built-up, and waterbodies increased by 148.84 km2, 304.15 km2, and 41.04 km2, respectively. However, the areas of barren land and vegetation decreased by 289.39 km2 and 204.64 km2, respectively. Furthermore, the Normalized Difference Vegetation Index (NDVI) and Normalized Difference Built-up Index (NDBI) were utilized to rapidly assess changes in LULC, and their trends were found to be consistent with the supervised classification results.

This study aimed to (1) investigate the effect of rock/soil mineralogy characteristics and Au content on the diversity of vegetation types at gold mine sites, and (2) determine the type of potential hyperaccumulator vegetation as a phytomining agent based on the Biological Concentration Factor (BCF). This study was conducted at the Ratatotok gold mine in North Sulawesi Province, Indonesia. The sampling locations consisted of 3 sites, i.e., Bulex, Yance, and Leon, and each site consisted of 5 sampling plots. Soil samples were taken from each sampling plot and then tested for gold content using the ICP-MS method and mineral content using the XRD method. Mineralized bedrock samples were also taken for mineralogical analysis through petrography. Data analysis of soil geochemistry was carried out descriptively. Quantitative descriptive analysis was also carried out to determine the dominant type of vegetation, which was potential for hyperaccumulators at the mine site. The results showed that gold content in the soil affected the diversity of vegetation, which was possibly due to gold stress, which affected plant growth. Based on the BCF value, three local plant species having potential as gold hyperaccumulators with moderate bioaccumulation ability (BCF>0.1-1) were found, namely Pteris vittata, Syzygium aromaticum, and Swietenia mahagoni.
