Abstract

Changes in natural resources have presented major problems for farming communities in rural areas. In general, farmers diversify their livelihoods in the non-agricultural sector without paying attention to the impact on the availability of natural resources in the future. Sand mining activity has become one of the short-term solutions for farming communities in rural areas. As a result, a problem such as land degradation occurs in the village, thereby generating negative impacts on the availability of nature for the next generation. This study aimed to analyze the causes of land degradation and describe the Integrated Farming System (IFS) as a solution to address the land degradation problem in Bambang Village, Wajak District, Malang Regency. This study applied a qualitative case study research design, and the research methods included in-depth interviews with 40 informants, observation, and Focus Group Discussion (FGD). The location of this study was determined by purposive sampling, considering that Bambang Village is one of the villages affected by land degradation due to sand mining. The results of the study revealed that land degradation was due to the vulnerability of the farming community; thus, another alternative was proposed to utilize part of the land (20%) as a sand mining area without neglecting environmental preservation as a reward for environmental services. In addition, IFS and the actors as ecopreneurs were considered as alternative solutions to meet the needs and to prepare the farming community resilience through ecological preservation by sustaining the ecosystem balance. In practice, IFS requires integration among stakeholders, farmers and concerned institutions.

Abstract

Small-scale gold mining is one of the sectors that contribute to the world's largest mercury contamination through the tailings it produces. Many efforts have been made to reduce mercury concentrations from tailings, one of which is by utilizing a combination of plants and bacteria. This study aims to analyze the combination of mercury-resistant biofilm-forming bacteria and local plants in the phytoremediation of small-scale gold mine tailings. This study used ten plant species divided into three groups and three biofilm-forming mercury-resistant bacteria (Bacillus toyonensis, Burkholderia cepacia, and Microbacterium chocolatum). Parameters observed included plant biomass, total chlorophyll, plant mercury content and media. The results showed that adding bacteria to each plant in the treatment had a different effect. Some plants with the addition of biofilm-forming bacteria had a higher wet weight than others. However, the addition of bacteria was not effective in increasing plant dry weight. The combination of biofilm-forming bacteria in the first and second plant groups reduced tailings mercury concentrations better than without the addition of bacteria. The combination of plants and bacteria in the third group gave higher media and plant mercury concentrations. This study shows that the addition of biofilm-forming bacteria can lead to increased remediation by plants. The second plant group treatment with a combination of P. indica, P. conjugatum, and S. sesban plants was the most effective in reducing tailings mercury content.

Abstract

The extraction of mineral resources from the bottom of the continental shelf is presently becoming very promising in terms of their current depletion on the continents. However, the development of the mineral resource base of the world ocean requires the creation of specialized equipment and technological schemes for its use. Such equipment should ensure safe, environmentally friendly, trouble-free operation in difficult hydrosphere conditions. One of the innovative ways of such development is the use of autonomous mining vehicles. The most energy-consuming part of the work of these vehicles is the process of lifting the loaded vehicle to the surface. This article discusses the optimization of energy costs for lifting an autonomous mining vehicle from the bottom of the continental shelf with the use of gases formed during the detonation of explosives.

Abstract

The Suluh river basin is subjected to soil erosion due to land use and land cover change. Yet, the impact of land use/land cover change soil erosion has not been applied in the study area. Thus, the current study focused on the modeling of the impact of land use/land cover changes on soil erosion in the Suluh river basin, the northern highland part of Ethiopia. Landsat image data sources were used to achieve the objectives. Ancillary data was also used. The nearest neighbor's fuzzy way of classification and the land change modeler for modeling, and the revised universal soil loss equation model for estimating the soil erosion rate were employed. Both qualitative and quantitative data were analyzed qualitatively and quantitatively. The study's findings confirmed that cultivated land, bare land, and built-up areas significantly increased while areas occupied by natural vegetation such as forest land, shrub lands, and grazing lands decreased at a rapid rate in between 1990 to 2018. The predicted results suggest the continuation of the trend up to 2048 if business as usual is continued. The annual mean of soil lost in the study area was about 36.31, 43.32, and 47.78 in the years 1990, 2002, 2018, and will be 56.54, and 71.62 tons per hectare per year in 2028, and 2048, respectively. When we consider 15 t ha−1 year−1 as the maximum tolerable soil loss (TSL) rate for ease of presentation, the areas above the TSL have increased from 88.3% in 1990 to 88.6% in 2002 and to 89.6% in 2018, and are expected to increase to 89.9% and 99.8% in 2028 and 2048 periods, respectively. Thus, land use and land cover change information and its impact on soil erosion should be taken under consideration by land use planners to apply sustainable land management activities in the Suluh river basin.

Abstract

Artisanal gold miners usually dispose of gold mine tailings in storage ponds or agricultural land used for farming. However, the gold mine tailings still contain heavy metals such as cadmium, copper, lead, and zinc and can lead to bioaccumulation in food chains. This study investigated the influence of composted cow manure as organic fertilizer on heavy metals (Cd, Cu, Pb and Zn) content in sweet potatoes grown on soil contaminated by gold mine tailing. The MZ119 clone sweet potato plants were grown on soils added with mixtures of gold mine tailings at ratios of 0% (control), 30%, 50%, 70%, and 100% (w/w), and composted cow manure (0, 250, 500, and 750 g/10 kg of soil). The results showed that the higher the ratio of gold mine tailings to the soil, the higher the accumulation of metals in sweet potatoes. According to the translocation factor (TF) value, heavy metals (Cd, Cu, Pb and Zn) accumulated higher in the shoots than in the roots of sweet potatoes. Accumulation of heavy metals in sweet potato occurred in the following order: Zn>Cu>Pb>Cd. This study recommends that sweet potatoes could be used for the phytoremediation of heavy metals (Cd, Cu, Pb and Zn) in polluted soils, but the plants may not be used for consumption.

Abstract

The Musi Hydropower-Plant catchment area is susceptible to soil erosion and sedimentation. Therefore, this research aimed to predict land use and land cover changes (LULCC) as well as their impact on soil erosion and sedimentation in the Musi Hydropower-Plant catchment area. The prediction of LULCC was calculated using Land Change Modeler module on IDRISI Terrset, while soil erosion and sedimentation were estimated with the Revised Universal Soil Loss Equation (RUSLE) and Sediment Delivery Ratio (SDR) models. The result showed that forest cover and paddy fields decreased significantly from 18.580 ha and 4.044 ha to 12.907 ha and 2.019 ha, respectively, in the periods of 1993 to 2019 and were predicted to reduce until 2032. Meanwhile, the built-up area and dry agricultural land increased from 818 ha and 2.116 ha in 1993 to 2.229 ha and 5.778 ha in 2019, which is expected to increase until 2032. The estimation of soil erosion rate also gave an increase from 75 t/ha/year to 113 t/ha/year, continuing to reach 122 t/ha/year until 2032. The escalation of soil erosion rate contributed to the change of sediment yield from 68.048 t/year in 1993 to 103.190 t/year in 2019,which is estimated to reach 111.028 t/year. These results are expected to be used by decision-makers and policymakers for the operation of the Musi Hydropower-Plant and the catchment area maintenance.

Abstract

In Algeria, solid waste management (SWM) is considered a major problem; most of this waste is dumped in landfills without any control. The Algerian authorities have developed a national strategy for the integrated management of urban solid waste by 2035 by working on the implementation, development and equipping of technical landfill centers (TLC). Therefore, the aim of this study was to help local authorities in choosing the optimal locations for the completion of the proposed TLC between municipalities. This research used a combination of the multi-criteria decision aid (MCDA) and geographic information systems (GIS). It combines two aggregation methods: Linear Combination of Weights (WCL) and Criteria Weighting. The analytical hierarchy process (AHP) pair-wise comparison method was applied for assigning weights to the 11 criteria that were divided into environmental, social, and economic criteria according to previous studies in the field and the characteristics of the HODNA area. The results showed that 22.56% is the most suitable location for a landfill site, especially on the southeastern side, while 20.70% was suitable and 18.40% was moderately suitable. Finally, the process of assessing the spatial suitability of public emptying sites based on the results obtained in the final digital map,4.76% of the landfill sites are located in inappropriate areas, 14.29% are located in less suitable areas, 33.33% are located in suitable areas, 33.33% are located in moderately suitable areas and 14.29% are located in very suitable areas.

Abstract

Land use changes become a problem that contributes to the decline in the watershed function and performance. Bedadung watershed divides Jember Regency, which has upstream from Mount Raung and a downstream Indonesian Ocean. During the last ten years in Jember, there has been a flood from the overflow of the Bedadung river, which is unable to accommodate water from upstream. It is alleged that the cause of flooding in upstream of the Bedadung watershed is land cover and land capability that has changed. The purpose of this study was to assess land use changes using a composite approach to Landsat 8 imagery and land capability index for the upstream of the Bedadung watershed. The results showed that land cover of the Kesambi sub-watershed during 1995-2020, forest decreased by 34.74%, settlements and open land decreased by 47.25%, dry land increased by 120%, while plantations and rainfed rice fields were fixed. The decrease in forest area can disrupt the water cycle, thereby increasing runoff volume and water discharge, causing flooding downstream of the Bedadung watershed and upstream of the Bedadung watershed. Land capability evaluation of the upstream of Kesambi sub-watershed, area of Bedadung watershed was mostly in class III, covering 5782.9 hectares (85.53%), class IV covering 214.8 hectares (3.18%), class VI covering 379.7 hectares (5.62%), and class VII covering 383.9 hectares (5.68%) with limiting factors of effective soil depth, land slope/slope, erosion sensitivity, and drainage. Areas with class III land capability covering land mapping units 1, 2, 3, 6, and 7 can be utilized as agricultural with good conservation technology, while land mapping units 4.5, and 8 are only capable for forest areas.

Abstract

Forest rehabilitation of Timor Island's dryland ecosystems using eucalyptus plants plays an important role in improving land cover but also in mitigating climate change and providing an alternative renewable energy source. The aim of this study is to explore the enormous energy storage potential of eucalyptus plants for commercial purposes using a high spatial resolution remote sensing approach. The Pléiades satellite imagery acquired on 10/09/2021 covering ca. 27 ha study area managed by Timor Tengah Selatan Forest Management Unit was used to identify the density of eucalyptus plants using Normalized Difference Vegetation Index (NDVI) values greater than 0.699. The density of eucalyptus plants is classified into low, moderate, and high tree density with NDVI values greater than 0.699 to 0.765, greater than 0.765 to 0.833, and greater than 0.833 to 0.901, respectively. The total potential energy production of the study area was estimated using a combination of assumed eucalyptus tree density, the calculated area of each density, and the average energy storage of individual trees. The results showed that the density of eucalyptus trees was classified as low, moderate, and high, with coverage areas of 6.8 ha, 12.9 ha, and 3.0 ha, respectively. The potential energy production of low, moderate, and high density approaches 1,103,432.33 MJ; 5,522,999.19 MJ; and 2,120,715.04 MJ, respectively, with a total estimated energy storage of 8,747,146.57 MJ. This obtained number of potential energy estimations indicates that forest rehabilitation of dryland ecosystems through eucalyptus plantations has a promising future as an alternative renewable energy source.

Abstract

Root system mechanical reinforcement through root-soil cohesion on slope stability is important. However, the root cohesion of Tectona grandis, Maesopsis eminii, and shrubs (Chromolaena odorata) on slope stability is rarely studied and modelled. This study aimed to model the mechanical effect of vegetation through root cohesion, namely teak (Tectona grandis), Maesopsis eminii, and shrubs (Chromolaena odorata). The study was conducted in a simultaneous landslide on January 1, 2020, that dominantly occurred on vegetated slopes of Sukajaya District, Bogor Regency, West Java. The Wu model's root cohesion (CR) was modelled on slope stability using a modified Bishop model. The modelling used the data from field and laboratory-measured. The study found that the presence of a root system increases slope stability's factor of safety (FOS). The root system of young Maesopsiss eminii produces the largest effect of FOS compared to the root system of shrubs, teak, and old Maesopsis eminii. The slope stability of vegetated slopes is a function of the CR and the effective root zone depth. The highest total CR of vegetation was teak with 0.398 kPa, followed by shrubs, young Maesopsis eminii, and old Maesopsis eminii with 0.202 kPa, 0.191 kPa, and 0.087 kPa, respectively. The effective root zone of teak, young Maesopsis eminii, and shrub were 500, 230, 140, and 66 cm, respectively.
