{"title":"Palm Waste Management and Environmental Sustainability in Sombo Community, Cameroon","authors":"Chi Chantal Ngwelum","doi":"10.2139/ssrn.3894522","DOIUrl":"https://doi.org/10.2139/ssrn.3894522","url":null,"abstract":"The management of waste produced during processing remains a major preoccupation to the local environment. This study aims to assess palm waste management on environmental sustainability, identify different waste management practices, environmental problems, and identify measures that can be set forth for proper waste management in Sombo. Soil and water samples were collected and analysed, while field observations and interviews were conducted. Results showed that almost all artisanal palm oil mills produce different types of waste, including empty fruit bunches (EFB), palm oil mill effluent (POME), palm kernel shell (PKS), palm pressed fibres (PPF), etc. but their disposal remain a major challenge. EFB, PPF, and kennel shells are usually managed by open dumping practices, which, when dry, are then burnt around the milling sites; POME waste is commonly emptied into the nearby land surface and water bodies. These practices have led to a change of soil texture, increase soil bulk density, increase total exchangeable bases, organic carbon, and organic matter content, and also decrease total soil nitrogen, carbon to nitrogen ratio (C:N ratio), increase soil available phosphorus, and decreases soil cation exchange capacity (CEC). Also, the water quality indices for three out of five nearby streams were poor (>50 units) and were unfit for consumption in one of the palm oil milling sites. Producers showed limited knowledge about these environmental effects caused by unsustainable waste management methods. The study concluded that Oil palm waste management practices in Sombo are unsustainable, and producers continue to use inefficient local technologies for palm oil production, thereby increasing the pollution rate of the environment. The development of a local, sustainable oil palm waste management strategy, sensitisation, and capacity building of producers is highly recommended for this community.","PeriodicalId":301349,"journal":{"name":"Agricultural Soil Science eJournal","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-07-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125770255","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 first part of the study describes the method of determining and characterizing areas with natural constraints (LFA) of specific type located in zone I in Poland designated by the Institute of Soil Science and Plant Cultivation – NRI (IUNG-PIB) on behalf of the Ministry of Agriculture and Rural Development (MRiRW) and the European Commission (EC). These areas were determined on the basis of the threshold values of the Nature and Tourism Index (WCPT) and the Index for the Valorisation of Agricultural Production Area (WWRPP). They have functioned in our country since 2019 and include 1233,7 thousand ha UAA. The second part of the study presents the functioning of farms located in municipalities with a high share of LFAs (specific type zone I) (at least 80% UAA LFA specific type zone 1 in total UAA) against the background of analogous farms in non-LFA municipalities that kept accounts for the Polish FADN continuously in 2016-2018. It was found that farms located in LFAs are characterized by lower capital value, older farm owners, and poorer quality of used soils. In addition, they incur lower costs per 1 ha of UAA, have worse production effects and lower factor productivity. Moreover, they have lower income per 1 ha of UAA, and thus smaller development opportunities.","PeriodicalId":301349,"journal":{"name":"Agricultural Soil Science eJournal","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-09-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132486641","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}
