As aquaculture plays a crucial in meeting global seafood demands, understanding the dynamics at the regional level become imperative. The study employed a multifaceted approach to assess the financial viability of aquaculture farming, technical efficiency of aquaculture production. By adopting a cluster based perspective, the research aims to unravel the intricacies of collaborative farming operations, identifying synergies that contribute to enhanced financial outcome. Insights garnered from this financial evaluation can provide stakeholders with strategic guidance for sustainable economic practices within the aquaculture sector. The research draws on a diverse set of data source, including financial records, production metrics, focus group discussions and questionnaire distributions. Statistical tools and econometric models are applied to quantify the relationships between various variables, providing a clear understanding of the factors influencing technical efficiency and financial Findings from this study showed that the price of labour, price of fish feeds and price of medicine had a significant effect on efficiency of aqua farming with a coefficient of 0.5468**,-0.7862**, -0.8896** respectively. The result of the technical efficiency , (25.0%) falls within the 0.71 - 0.8 range, indicating a high level of technical efficiency of aqua farmers. This is followed by those in the 0.31 - 0.4 and 0.51 - 0.6 ranges, each with 11.2% of farmers. In contrast. The result of the BCR showed a significant variation in profitability highlights of aqua farming operations in the study area are more financially rewarding, with a net return on investment (ROI) of 0.58. However, the technical efficiencies and productivities of aqua farmers in clusters were significantly high regardless of how biases were corrected, implying that participation in cluster group is positively related to increases in aqua farmers output.","PeriodicalId":12791,"journal":{"name":"GSC Advanced Research and Reviews","volume":"22 3","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-03-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140362021","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}

Adaptation to salinization, one of the great challenges of modern agriculture, is possible through the use of halotolerant varieties which could be selected early during seed germination. The general objective of this study is to evaluate the effect of salinity on the germination of peanut, cowpea, millet and sorghum. The effect of NaCl (0, 40, 80 and 120 mM) was tested on seed germination for one week at 30°C in a culture chamber. The parameters evaluated are: the final percentage of germination (FG), the germination vigor index (GVI), the coefficient of velocity of germination (CVG), the percentage reduction in germination compared to the control (PRG) and the daily average germination (DAG). The FG, GVI and CVG of millet, cowpea, sorghum and peanut show significant differences (p<0.01) for each NaCl concentration. On the other hand, DAG and PRG give significant differences only at 80 mM and/or 120 mM NaCl. FG, CVG, DAG and GVI decreased with increasing salinity for all varieties unlike PRG. Cowpea (V4) are less sensitive to salinity than peanut (V3), which tolerate NaCl better than cereals. Millet (V5) is more resistant than sorghum (V7). The increase in NaCl led to a significant difference in germination. Cowpea (V4) would be more osmotolerant than peanut (V3) which is more tolerant than cereals such as millet (V5) and sorghum (V7) to salinity. These varieties would be the most recommended for successful cultivation in a saline environment.","PeriodicalId":12791,"journal":{"name":"GSC Advanced Research and Reviews","volume":"4 3","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-03-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140364558","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}

It examines various aspects such as the current state of LNG usage, its environmental impacts, technological advancements, regulatory frameworks, and the challenges and opportunities associated with its integration into the energy mix. Through a comprehensive analysis, this review aims to provide insights into how project management principles can facilitate the effective implementation of LNG projects to support the transition towards a carbon-neutral future. The transition to a carbon-neutral global economy is an imperative challenge of the 21st century, necessitating a profound shift in energy systems and practices. At the forefront of this transition, liquefied natural gas (LNG) has emerged as a potential bridge fuel, offering a pathway towards decarburization. This project management review delves into the multifaceted role of LNG within the context of global carbon neutrality efforts, examining its current usage, environmental implications, technological advancements, regulatory frameworks, and the associated challenges and opportunities. Through a comprehensive analysis, this review aims to shed light on how project management principles can effectively facilitate the implementation of LNG projects to support the transition towards a carbon-neutral future. LNG's emergence as a potential bridge fuel stems from its relatively lower carbon intensity compared to other fossil fuels. As nations strive to reduce greenhouse gas emissions and meet their commitments under the Paris Agreement, LNG presents an opportunity to mitigate climate change while addressing energy security and economic development objectives. However, a nuanced understanding of LNG's role requires a thorough examination of various dimensions. Firstly, the current state of LNG usage underscores its growing significance in the global energy landscape. With LNG trade reaching record highs in recent years, countries are increasingly turning to LNG to meet their energy needs. Major LNG-producing nations such as Qatar, Australia, and the United States have invested in liquefaction infrastructure, enabling the export of LNG to markets around the world. Additionally, LNG is utilized across diverse sectors, including power generation, industrial processes, transportation, and residential heating, highlighting its versatility and applicability. Despite its potential benefits, LNG is not without environmental impacts. The extraction, production, and transportation of natural gas, the primary component of LNG, can result in methane emissions, a potent greenhouse gas. In conclusion, LNG has emerged as a potential bridge fuel in the transition towards a carbon-neutral global economy. Its relatively lower carbon intensity, versatility, and scalability make it a viable option for reducing greenhouse gas emissions while meeting energy demand. However, realizing the full potential of LNG requires care","PeriodicalId":12791,"journal":{"name":"GSC Advanced Research and Reviews","volume":"40 5","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-03-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140364268","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}
