Plankton net of mesh size 55µm was used to collect plankton samples from below the water surface, after towing for 5 minutes. The content was emptied into plastic containers and fixed immediately with 4% formalin in the field for preservation. After 48hrs in the laboratory, the preserved plankton samples were concentrated to 10 ml. The concentrated sample was agitated to homogenize before pipetting 1ml sub sample with sample pipette. Enumeration and identification were performed using a zeis inverted microscope at x400 and x 1000 magnification. Species identification was done using recommended keys and guides. A total of six hundred and fifteen (615) individual organisms comprising of thirty-five (35) species belonging to five (5) taxonomic groups were recorded from Mbiakong River. The most abundant group was the Bacillariophyceae which was represented by 12 species (302 organisms) consisting of 49.11%. This was followed by Chlorophyceae represented by 10 species (199 organisms) consisting of 32.36%, Cyanophyceae represented by 12 species (109 organisms) consisting of 17.72%, Euglenophyceae represented by 1 species (3 organisms) consisting of 0.33% and the least abundant was the Dinophyceae represented by 1 species (2 organisms) consisting of 0.14%. The study revealed that species composition and abundance was high in June.","PeriodicalId":186239,"journal":{"name":"Journal of Ecology & Natural Resources","volume":"92 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122672787","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}

Based on geographical location and lifestyle, an individual's contribution to the global carbon footprint has been estimated in this study. This study examines the household carbon footprint in different rural and urban regions of West Bengal. It analyzes the difference of contribution of the factors based on one’s geographical location and how an individual's socioeconomic status affects carbon footprint. Data on the consumption of goods and services resulting in GHG emissions was gathered at the household (N=243) level through a questionnaire survey in different districts of West Bengal. The average carbon footprint in rural areas is estimated to be 0.56 tones CO2e per capita per year. In urban areas, it is 2.33 tones CO2e per capita per year significant difference is found in the annual per capita carbon footprint (household, travel, lifestyle, and total carbon footprint) among the various income groups of rural and urban areas. Another significant difference is found among different monthly expenditure categories between urban and rural households. Based on the information given by the respondents of the rural and urban areas the difference regarding electricity consumption, travelling details, monthly expenditure category, type of energy used, cooking fuel, annual household, travel, and lifestyle carbon footprint have been discussed graphically. This study looked at the sectoral contribution (activity-wise, e.g., cooking, transportation, etc.) and the rural-urban disparity in the individual carbon footprint.","PeriodicalId":186239,"journal":{"name":"Journal of Ecology & Natural Resources","volume":"183 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121829799","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}

Water governance in Cambodia has been challenged by too much water in the wet season, causing flooding, and by too little in the dry season, inducing drought. A proper water practice is needed in place to manage water and reduce water security to support the development of the country. This study is designed to explore the best practice of water management in Cambodia. To provide an answer to this exploration, the study reviews the relevant literature and undertakes a case study of indigenous water management practice in the Tonle Sap Lake. In doing so, the study examines the Metuk water management practice and examines how it contributes to improving water security and reducing its impacts on the livelihoods of local communities. It concludes that the Metuk system is a best practice for water management, which is operated by local communities, using local human and financial resources, with little hands of government agencies from all levels, to address future water governance in Cambodia.","PeriodicalId":186239,"journal":{"name":"Journal of Ecology & Natural Resources","volume":"47 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122187116","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}

Seven Local Government Areas within the region were selected for the study. Two (2) villages in each Local Government were further sampled making a total of 14 villages. The study employed both descriptive and quantitative method of data analysis. Twenty-eight (28) structured questionnaires out of 392 were distributed to Fourteen (14) communities, together with personal interview conducted at the sampled communities. SPSS manipulation using multiple regression analysis revealed that the Southern Akwa Ibom State is heavily endowed with natural resources and in the quest of harnessing the resources, a wide variety of ecological problems emerged such as oil spill, forest destruction, gas flaring, water pollution, air pollution, open defecation, ground water contamination, soil acidity and biodiversity loss. The study further noted that given the ever-increasing ecological degradation, the livelihood and socio-economic status of the region have been modified, jeopardized or absolutely destabilized with poor crop yield, fishery loss, soil infertility and land contaminant. It was however recommended that an impact prediction and proper assessment of anthropogenic activities including mineral and non-mineral exploitation within the area be carried out. This is with a view to touching essentially on the change brought about by anthropogenic activities including, sand dredging, deforestation, gas flaring as well as oil spill which subsequently impact upon agricultural productivity and environmental resources in the region. Also, all the key stakeholders in the various companies operating within the region including oil and gas industry should inject some funds and re-direct their attention toward effective ecosystem management for improved livelihood sustainability.","PeriodicalId":186239,"journal":{"name":"Journal of Ecology & Natural Resources","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116833627","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 tremendous accumulation of molecular data is revealing a vast diversity of microbial groups, as well as unique microbial functions. Plants are part of a varied ecosystem in their natural habitat, which includes numerous and different microorganisms in the soil. Some of these microbes, such as mycorrhizal fungi and nitrogen-fixing symbiotic bacteria, have long been known to improve plant performance through enhancing mineral nutrition. A substantial quantity of data on the structure and dynamics of plant microbiota, as well as the functional capacities of isolated community members, is currently available. The adoption of appropriate delivery techniques and formulations, as well as smart, knowledge-driven microbe selection, is required. Plant-microbe interactions may now be studied in greater depth thanks to modern biotechnology. In this review, we look at the interaction between the soil, the host, and the microbial population, as well as their involvement in plant sciences, to see what we can learn about the ecosystem function of plants and symbiotic microorganisms, which will help us to improve agricultural techniques.","PeriodicalId":186239,"journal":{"name":"Journal of Ecology & Natural Resources","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128483332","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}

As the interaction between land and water grows in its function and relevance, economic and regulatory attention should be paid to the behavior patterns of such connecting facilitators on the oceans. Against this backdrop, the notion of the \"Blue Economy\" was born. A review of the literature is conducted in order to determine a suitable definition for the Blue Economy. These definitions are examined in terms of the very minimum requirements for a Blue Economy. The article also tries to organize the many sorts of activity related to ocean services. It is really done with the goal of identifying what one would consider to be the primary considerations for the Blue Economy's growth. Article further proposes that blue oceans can be created via radical innovation, disruptive innovation, frugal innovation, and purely differentiation strategy and focused differentiation strategy rather than only value innovation. Furthermore, we suggest that strategy canvas is applicable not only for value innovation but all types of innovation. We, thus extend the boundaries of sources of blue oceans. Lastly, we explore if sustainable competitive advantage or blue oceans ae better sources of profitability.","PeriodicalId":186239,"journal":{"name":"Journal of Ecology & Natural Resources","volume":"102 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129321179","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 burgeoning population causes serious pressure on land to fulfill the increasing food demand, animal feed, fibre as well as fuel, which leads to adopting practices such as intensive tillage, monoculture, excessive and improper use of inorganic fertilizer, use of agro-chemicals, deforestation, over-grazing, among others. These modern practices of agriculture are considered to be the major unsustainable practices leading to soil health degradation. Some of these practices lead to climate change, which in turn accelerates the rate of soil health degradations. Perennial woody plant based systems has a prime role towards improvement of soil health to sustain production systems. Thus, agroforestry systems is win-a-win strategy which posses various agroforestry systems that are practiced by farmers over the ages and these systems are devoid of intentional intensification of soil for the production of tree in combination with agricultural or forage crops in the same land. This system is distributed and practices most parts of the tropics in the world with varying different models which depends on bio-physical, socio-economic attribute along varying ecological services specific to a particular continent, region, country or community. Organic residues input and its decompositions, nitrogen fixations, nutrient cycling process, carbon sequestration, erosion control and microclimate amelioration etc improve the soil health under agroforestry systems. This paper gives a comprehensive insight on agroforestry importance, history, scope and potential along with its role towards soil health management in the tropics of the world.","PeriodicalId":186239,"journal":{"name":"Journal of Ecology & Natural Resources","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124552816","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}
