  • Preliminary Studies on Existing Scenario of Selected Soil Property in
           Cheddikulam DS Division Vavuniya, Sri Lanka

    • Authors: M.A. R. Aashifa, P. Loganathan
      Pages: 1 - 11
      Abstract:  This study was conducted to quantify the spatial variability of soil properties, use this information to produce accurate map by means of ordinary kriging and find the ways to reclaim the problem soil and make suggestions to cultivate the crop variety which is suitable for the existing soil property.70 sampling points were selected for that research using stratified random sampling method. Stratification was based on the type of land cover, and following land cover patterns were identified forest patches, agriculture land patches, grass land patches and catchments. Sampling points were randomly selected from each land cover types. Minimum distance between two adjacent sampling points was 500m. Soil samples were analyzed for pH, EC, exchangeable K, available P. In each location, soils were collected from top to - 30 cm depth (root zone) using a core sampler and sub soil samples were collected around the geo-reference point to obtain a composite sample. Geostatistical tool of the software (ArcGIS 10.2.2. trail version) was used to construct semi-variograms and spatial structure analysis for the variables. Geostatistical estimation had done by kriging. 13% of agriculture land area was acidic soil and 5.7% alkaline soil. 13% of agriculture land area was identified as saline soil. 67.11% of agriculture lands contain more phosphorous concentration than the optimum range. 3.4% agriculture lands contain higher potassium concentration than the optimum range. 98% of forest lands and 100% of grass lands contains phosphorous concentration higher than the optimum range. But forest lands and catchments shows lower level of potassium concentration. 22% of grass lands contain higher potassium than the optimum level. Agriculture practices leads to change in the soil hence identified soil problems should be reclaimed in order to maintain the fertility of soil for sustainable production. Proper management of soil can be a better solution for supporting the successful agricultural activity of community in future and socio-economic development of this region.INTERNATIONAL JOURNAL OF ENVIRONMENT

  • Households’ Fuel Wood Dependence, REDD+ and Gender Coping Strategies: An
           Empirical Review and Policy Implication in the Northern Region of Ghana

    • Authors: Jamal Mohammed, Anthony Kofi Osei-Fosu, Hadrat Yusif
      Pages: 12 - 31
      Abstract: This paper reviewed existing literature on fuel wood dependence, REDD+ and gender coping strategies. Out of 180 sets of empirical studies in this domain, twenty five (25) were considered to have a bearing on our topic. The review showed that REDD+ policy in the Northern Region has not provided for REDD+ finance to curb the possible negative effects of the implementation of the programme. It is recommended that there should be a clear cut policy on REDD+ finance for those who depend on the forest. It is also recommended that there should enough public education for communities’ acceptance and integration.INTERNATIONAL JOURNAL OF ENVIRONMENT

  • Stakeholders Behaviour towards Clean India Mission's New Municipal
           Solid Waste Collection System in Chandrapur City, Central India

    • Authors: R. K. Kamble, Namrata R. Nimgade, Priyanka V. Patil
      Pages: 32 - 43
      Abstract: The study was carried out to analyze behavioural pattern of stakeholders–inhabitants of Chandrapur city as well as employees of Chandrapur Municipal Corporation (CMC)–towards the "Clean India Mission" scheme as compared with previous scheme of women’s self help group. For behavioural change analysis field survey was carried out in October 2015 in Chandrapur city. Total 41 respondent including inhabitants and employees of CMC were interviewed. The results of the study shows that, previously municipal solid waste (MSW) collection was irregular (41.66%) however, since the implementation of this new scheme it has become regular (100%). Enhanced MSW collection frequency was observed (once a day, 83.33%) with alternative staff arrangement in case of staff is absent. The work was monitored by officials (79%) which were previously not existing. In previous scheme, extra money was charged for collection of MSW, however no such charges are levied in this new scheme. Satisfaction rate of this new scheme was 95.83% among inhabitants. As reported by MSW collection employees, there was awareness among inhabitants about dry and wet waste (41.17%). The employees were satisfied with the scheme (94.11%) as there is improved and timely salary with a job guaranty.INTERNATIONAL JOURNAL OF ENVIRONMENT

  • Evaluation of Methane and Carbon Dioxide Emission Decrease Through Waste
           Composting

    • Authors: Apinan Pitaratae, Somsak Pitaksanurat, Atsamon Limsakul
      Pages: 44 - 55
      Abstract: The organic waste disposal under anaerobic conditions emits Methane, which causes increased global warming. This study attempts to find the emission factor in windrow waste composting systems from two sizes of gathered organic waste piles. Designed to compare two groups of composting piles, one pile consisted of 500 kilograms of waste originating from local authorities while the other amounted to 250 kilograms of waste collected from households. With six piles of each type, aeration was done by manual turning and emissions were sampled in closed flux chambers and analyzed by gas chromatographs. A control experiment, modeling landfill sites, was set up in a one x one x one meter hole. Results from the experiment showed that emission ratios from the 500 kg was 1.3613 x 10-3 g CO2-eq kg-1 wet waste, and 1.3427 x 10-3 g CO2-eq kg-1 wet waste from the 250 kg experiment. The 500 kg experiment decreased emissions by 0.059185 g CO2-eq kg-1 wet waste and the 250 kg experiment, emissions decreased by 0.059206 g CO2-eq kg-1 wet waste when compared to the control group. In summary, pile size has no effect on emission ratios. Statistical testing found no significance difference between emissions from the 500 kg compared with the 250 kg. This study tells us that massive landfill or waste composting is difference effect.INTERNATIONAL JOURNAL OF ENVIRONMENT

  • Recycling of Date-Palm Fiber to Produce Pleurotus Cornucopiae Var.
           Citrinopileatus Mushroom

    • Authors: Mustafa Nadhim Owaid, Sajid Salahuddin Saleem Al-Saeedi, Idham Ali Abed
      Pages: 56 - 65
      Abstract: In this study, some local available organic matters, which are including wheat straw (Triticum aestivum), sawdust, and fiber of date palm (Phoenix dactylifera L.), were used for growing and cultivating of bright yellow oyster mushroom Pleurotus cornucopiae var. citrinopileatus. The possibility of using date palm fiber (in mixtures with other organic residues) as a substrate for the cultivation and production of fruiting bodies of P. cornucopiae var. citrinopileatus was investigated. This mushroom is capable of biorecycling and utilization of some mixtures of lignocellulosic substrates successfully, especially the mixture S3 (50% wheat straw, 30% sawdust, and 20% date palm fiber). The lower mycelia completion time was 17 days, that shown in bags of the S3 substrate. Date-palm fiber substrate exhibited best growth intensity level (moderate) significantly (p<0.05). The total yield and biological efficiency percent recorded approx. 90 g and 23% on the S3 substrate respectively, as a higher percent significantly (p<0.05), while sawdust substrate alone was an unsuitable medium for cultivation and production of this mushroom. Finally, the use of date-palm fibers in mixtures is usefulness in producing a fresh edible and medicinal mushroom.INTERNATIONAL JOURNAL OF ENVIRONMENT
