Abstract

The identification of potential habitats of the largest and smallest flowering parasitic Rafflesia in the Philippines is a prerequisite in conservation of species and preservation of their habitats which have been being degraded due to anthropogenic activities and climate change. This research aimed at revealing the possible habitat suitability for Rafflesia schadenbergiana Göppert ex Hieron and Rafflesia consueloae Galindon, Ong Fernando throughout the Philippines using Geographic Information Systems (GIS). The selection criteria in this research were based on four parameters (elevation, annual rainfall, temperature, and land use / land classification) identified during the extensive literature review. The generated map shows that the optimal growth of the Rafflesia schadenbergiana can be observed with a temperature range of 20–22°C while Rafflesia consueloae can thrive within 24°C to 25°C. The importance of these criteria was evaluated using a pairwise comparison method and the final weight was computed for each criterion. Setting up of the values suiting the subject species was followed by weighted overlay analysis. The final output is the distribution and habitat suitability of the subject species.

Abstract

Due to the massive amounts of freshwater consumed in dairy industries, as a result, thousands of liters of wastewater were produced as one liter of milk produces 10 liters of wastewater which represents a major threat to the surrounding environment and aquatic life. The application of a promising technology called “effective microorganism (EM)” was the key solution due to its low operating cost, low technology, and eco-friendly condition. Three different effective microorganisms were used, such as Bacillus bacteria (EM1), Staphylococcus bacteria (EM2), and EM stoste + Molasses (EM3). EM1 and EM2 were isolated from the dairy wastewater by using streaking for isolation on an agar plate process, while EM3 was prepared by mixing 12 % EM stoste, 6% molasses, and 82% distilled water. A laboratory pilot consists of aeration and final settling tanks, both tanks followed by an activated carbon filter. Four trials were performed, the first trial was without any EM, the second trial was adding EM1 with a dose of 50 ml to the aeration tank, the third trial was EM2 with a dose of 50 ml to the aeration tank, finally adding EM3 with a dose of 30 ml to the aeration tank. Results showed that using Bacillus bacteria (EM1) was the most effective trial as it was effective in reducing TSS (total suspended solids), BOD (biological oxygen demand), COD (chemical oxygen demand), TN (total nitrogen), and TP (total phosphorous) concentrations by removal efficiency of 93%, 96.2%, 95.9%, 94%, and 64%, respectively which were below the limitations of the Egyptian code for reuse for irrigation purposes.

Abstract

Mining activities specifically Coal Mining have been long testified to be one of the major contributing factors to environmental crisis, with Acid Mine Drainage (AMD) as one of the leading indicators. The purpose of this study was to assess the potential of AMD generation from neutralized coal mining tailings. In order to achieve the ultimate objective of the study, analysis of chemical composition and mineral content of the tailings using XRF (X-Ray Fluorescence) and XRD (X-Ray Diffraction) respectively, lastly, a static analysis such as ABA (Acid Base Accounting) and TCLP (Toxic Characteristic Leaching Procedure) were also conducted. The results have shown that the studied tailing samples had relatively higher Acid Potential (19 kg CaCO3/t to 20 kg CaCO3/t) versus the Neutralizing Potential (NP) (14 kg CaCO3/t to 18 kg CaCO3/t). It was also found that the Net Neutralizing Potential Ratio (NNPR) is less than zero (-1.5 kg CaCO3/t to -5.40 kg CaCO3/t which indicates that the tailings have the potential to generate acid. The low concentration of CaO indicates acidic potential of the samples because CaO is a buffering mineral. Based on the results of the study, it was concluded that Mine Tailings has the potential to generate acid; therefore, the contamination to the nearby watercourses is extremely possible if necessary remedial actions should be considered.

Abstract

Irrigation improves the productivity of agriculture in any country. Irrigation is viewed as a fundamental approach to ensure food security, improve crop productivity, income of smallholder farmers, ensure food security, alleviate poverty and improve the economy of the farming community by generating additional income. As a result, the goal of this study was to identify prospective irrigated lands for agricultural land management in the Wanka watershed in northwestern Ethiopia using geospatial technology and multi-criteria decision-making analysis. Identifying sites for surface irrigation for agricultural land management is not a simple task, which needs consideration of many criteria such as slope, soil texture, soil depth, soil drainage, land use/land cover and distance from the water supply were used to determine the best possible location. Each factor was categorized into highly suitable, moderately suitable, marginally suitable and currently not suitable. The final result showed that the watershed had a high opportunity for surface irrigation. About 498 km2 of the watershed's total area is potentially suitable for surface irrigation, whereas the remaining 443 km2 is not. In the research area, there is sufficient land area accessible for surface irrigation development if those locations with highly suitable to marginally suitable areas are properly utilized.

Abstract

This study was conducted to determine mercury contamination contained in soils in Kalirejo sub-district, Kulon Progo, Indonesia. This contamination occurred as a result of traditional gold mining activities that used the amalgamation method of mercury. Soil samples were collected from 6 sites; one site was located in an uncontaminated location, and 5 sites in contaminated soil were taken from 10 meters distance from the tailing ponds. Samples were collected from each site at 30, 60, and 90 cm depths. Mercury concentrations in each sample were measured according to the US EPA method, using Mercury analyzer type VM-3000. Mercury concentrations in uncontaminated area at 30, 60, 90 depths were 0.19 mg/kg, 0.02 mg/kg, and <0.0001 mg/kg respectively. These values did not exceed the quality standard according to Government Regulation No 101 The Year 2014 concerning Hazardous Waste Management of 0.3 mg/kg. Meanwhile, mercury concentrations around the tailing ponds were 0.30 to 22.51 mg/kg, which exceeded the quality standard.

Abstract

The present study assessed the acceptability of the rehabilitation efforts conducted by the University of the Philippines Los Baños (UPLB) Bioremediation Team in an inactive mined-out area in Mogpog, Marinduque, Philippines from 2006 to 2016. A researcher-made semi-structured questionnaire was used to interview key informants, like members of the local government unit (LGU) of Mogpog, Marinduque, head of the Provincial of Environment and Natural Resources Office (PENRO), and selected residents of Barangay Ino and Capayang near the mining site. The selection of the respondents (n=112) was done through a stratified random probability sampling among residents ages 20 years old and above to determine their awareness and knowledge about the mined-out area before and after its rehabilitation. Interview with key informants revealed different functions towards the rehabilitation of the mined-out area. Results also showed that 59% of the respondents were aware of the rehabilitation efforts made on the site, and 98% of them strongly agreed on the presence and harmful effects of toxic chemicals in the area.   They also strongly agreed that the rehabilitation efforts had a positive impact on the environment, biodiversity and the community nearby. Interventions implemented by the government and other agencies are likely to succeed with the help of the nearby community and therefore, the same community can also be the best judge to determine the acceptability of the interventions.

Abstract

The rehabilitation of abandoned mines begins with the characterization and ranking of these mines. Based on this, countries, organizations, and individual researchers have developed tools for ranking abandoned mines for rehabilitation. This paper comments on the issues of abandoned mines which include their definition and the problems they possess. It then critically examines the criteria used by different tools to prioritize the rehabilitation of abandoned mines. It showed that there is a sharp increase in the number of academic tools developed for the ranking of abandoned mines over the years. These tools demonstrated how the parameters disregarded in official ranking tools can rank the abandoned mines for rehabilitation. The paper recommends that the main issues of abandoned mines and their rehabilitation be part of the criteria of ranking these mines for rehabilitation. The inclusion of such parameters in the ranking criteria promises to improve the accuracy of the ranking process. It will go a long way in ensuring that the ranking tools provide the correct advice on what strategies can be used to rehabilitate these mines.

Abstract

Coal fly ash (CFA) is a coal-burning by-product containing macro and micronutrients, and it is the potential material for improving available P in Ultisols. Phosphate-solubilizing bacteria (PSB) play a role in phosphorus solubilization. This study aimed at elucidating the potential use of phosphate-solubilizing bacteria to optimize the use of coal fly ash for increasing soil available P. This study was conducted in two stages, namely isolation of indigenous PSB from an Ultisol and application of the PSB and CFA to improve soil available P. Five indigenous PSB isolated from the soil had the ability to dissolve phosphate. Isolate B5 could dissolve 9.89 ppm P and had a 99.57% closeness to Pseudomonas stutzeri. The application of 20 and 40 t CFA ha-1 increased the soil pH by 4.2% and 7.2%, respectively. Increasing the dose of CFA decreased the content of available P by 50.6%. However, the combination of PSB and 20 t CFA ha-1 increased soil available P, plant growth, plant dry biomass, and P-uptake by plant.

Abstract

This paper deals with the evaluation of rehabilitation of spoils depositions of asbestos mine MABE, Kozani, in northern Greece, eight years after restoration works. In order to succeed this, we monitored all the restoration actions during the period of restoration works, as well as during the post-restoration period of eight years after the end of restoration works. The evaluation showed that the mining area subjected to restoration is now characterized, eight years after restoration, by high land stabilization, satisfactory woody vegetation cover, low erosion risk, low concentration of asbestos fibres in the air and water, and furthermore it was aesthetically integrated in the surrounding landscape. Even though the great difficulties due to the huge pile of spoils depositions that had been created during mining, the selection of the specific restoration actions greatly contributed to the achievement of a sustainable post-mining environment. The suitable land transformation, and the satisfactory establishment of forest vegetation created a safe from asbestos fibres environment, and for a sustainable future land use of the previous mine area as forest, which in many cases is the most appropriate post-mining use for contaminated mining areas.

Abstract

Indonesia is one of the countries with the largest Au deposited. Gold mining has been the backbone of Indonesia’s economy. However, Indonesia also faces huge problems of Artisanal and Small Scale Gold Mining (ASGM) in a number of areas of Indonesia. A number of problems follow this Au mining method, including environmental, social and economic problems. Green innovation and technologies are needed to solve the problems. To date, Au agromining has been considered as a technology that can solve the numerical problems of Au conventional mining in the sector mentioned before. Gold agromining also has been proposed as a solution for the ASGM problem in Indonesia. However, until now, there have been no reports on the use of Au agromining technology in Indonesia. In fact, agromining research has been very advanced and is considered very prospective. This paper outlines the potentials of Au agromining to be implemented in Indonesia to overcome the social and environmental problems of ASGM.
