This study evaluates the impacts of climate change on food security and sustainable water resources in Nigeria. Stratified samples were taken from North Central States of Benue and Plateau, and South-South Cross River State and Akwa-Ibom. These four states are among the thirty six states in Nigeria that have been badly hit by climate change. This study used soft and hardware computer applications including German 12 handheld GPS, and Integrated Land and Water Information System (ILWIS), for data collection. Quantitative and qualitative data were collected for the evaluation. The GIS information software package was used to manipulate and perform feature identification, recognition, classification, calculation, and ground-trotting. A structured questionnaire was also used to collect data on some livelihood activities, the influence of livelihoods activities on water resources, food security, and climate change impacts. Data analysis, found that the forest and water bodies are shrunken. Industrial activities such as oil exploration and exploitation, mining, by Multinational Corporations, illegal mining, grazing, unsustainable farming practices, fishing and hunting for bush meats, bush fire, timber exploitation and deforestation have contributed to climate change. The study recommends climate action and climate diplomacy, building local capacity for resilience, engaging the private sector, partnerships and international assistance.
本研究评估了气候变化对尼日利亚粮食安全和可持续水资源的影响。分层抽样取自中北部的贝努埃州和高原州,以及南部的克罗斯河州和阿夸伊博姆州。这四个州是尼日利亚受气候变化严重影响的 36 个州之一。这项研究使用了软硬件计算机应用软件,包括德国 12 型手持式全球定位系统和水土综合信息系统(ILWIS)来收集数据。为评估收集了定量和定性数据。使用地理信息系统信息软件包来操作和执行地物识别、识别、分类、计算和实地考察。此外,还使用结构化问卷收集了一些生计活动、生计活动对水资源的影响、粮食安全和气候变化影响等方面的数据。数据分析发现,森林和水体正在萎缩。跨国公司的石油勘探和开采、采矿、非法采矿、放牧、不可持续的耕作方式、捕鱼和狩猎丛林肉类、丛林火灾、木材开采和砍伐森林等工业活动都加剧了气候变化。研究报告建议采取气候行动和气候外交,建设当地的抗灾能力,让私营部门参与进来,建立伙伴关系并提供国际援助。

Context Transformations of Panel-data values are routinely made for qualifying datasets with the intention of enhancing the quality of the decision-making-intel that may be gleaned from inferential-testing. Interestingly, there seems to be a “Spill-Over” of this “Conditional Data-Transformation Imperative” that impacts the development and execution of forecasting-protocols.Focus We offer inferential-tests of Transformations applied to randomly selected S&P500 Firm-datasets to address the following research Questions of Interest:(1) Is there Transformation-Jeopardy if the wrong Box-Cox-Carvalho-Transformations are selected re: (a) The Capture Rate Profiles for the 95% Forecasting Prediction Internals Or (b) The Relative Absolute Forecasting Error [RAFE] for the Forecasting Predictions?(2) In a consulting context, when Transformations are correctly used, the client almost always requires that the forecasts be re-transformed to the original measure of the data. Is there a Re-Transformation-Jeopardy re: the forecasting decision-intel needed to inform the decision-making processes of the client?Results We found that the theoretical expectations for the 95% Forecasting Prediction Intervals were founded even if the transforms were not to have been correctly selected. However, if the wrong transformation was to have been selected, non-trivial RAFEs are the likely result. Finally, if the correct transformation was to have been selected, re-Transformations to the original data-measures likely will inform the decision-making processes.
为了提高从推论测试中获得的决策信息的质量,通常会对面板数据值进行上下文转换。有趣的是,这种 "条件数据转换要求 "似乎对预测方案的开发和执行产生了 "溢出效应"。重点 我们对随机选取的 S&P500 公司数据集的转换进行推理测试,以解决以下感兴趣的研究问题:(1) 如果选择了错误的 Box-Cox-Carvalho 转换,在以下方面是否存在转换危险:(a) 95% 预测预测内部的捕获率曲线或 (b) 预测预测的相对绝对预测误差 [RAFE]?(2) 在咨询中,当正确使用转换时,客户几乎总是要求将预测重新转换为数据的原始量度。结果 我们发现,即使没有正确选择变换,95% 预测预测区间的理论预期也是成立的。但是,如果选择了错误的转换,则可能会产生非小的 RAFE。最后,如果选择了正确的转换,对原始数据措施的重新转换可能会为决策过程提供信息。

This study is on the impact of tax revenue on income inequality and poverty in Nigeria from 1995 to 2022, variables used are total tax revenue as the independent variable, poverty rate and income inequality proxy by Gini coefficient as dependent variables. Multiple taxation, corruption, value added tax, policy failures and inefficient fiscal operations are identified by this study as contributive factors to income inequality and poverty in Nigeria. The findings revealed that the relationship between total tax revenue and poverty rate is positive (as against apriori expectations). The estimated results are R2 at 0.626243 and adjusted R2 0.588253 which are the coefficient of determination or explainability of the independent variable (TTR) for the dependent variable (GIN), 63% of the changes in the dependent variable (GIN) is caused by changes in (TTR). The study concluded that tax revenue has a significant positive impact on poverty rate and income inequality in Nigeria. Major recommendations are that the Ministry of Finance, the Federal Inland Revenue Service (FIRS) the state board of Internal Revenue Service, the Joint Tax Board (JTB) should improve the dividend of taxation through accountability, transparency, better revenue generation and tax revenue expenditure on infrastructure and basic services.
本研究涉及 1995 年至 2022 年税收对尼日利亚收入不平等和贫困的影响,使用的变量包括作为自变量的税收总额、作为因变量的贫困率和以基尼系数表示的收入不平等。本研究将多重征税、腐败、增值税、政策失误和财政运作效率低下确定为造成尼日利亚收入不平等和贫困的因素。研究结果表明,税收总额与贫困率之间的关系是正向的(与先验预期相反)。估计结果 R2 为 0.626243,调整后的 R2 为 0.588253,这是自变量(TTR)对因变量(GIN)的决定系数或可解释性,因变量(GIN)63% 的变化是由(TTR)的变化引起的。研究得出结论,税收对尼日利亚的贫困率和收入不平等有显著的积极影响。主要建议是,财政部、联邦内陆税收局(FIRS)、国内税收局各州委员会、联合税收委员会(JTB)应通过问责制、透明度、更好的创收以及用于基础设施和基本服务的税收支出来提高税收红利。

The need for adequate food production in Nigeria is increasingly becoming a must-achieved objective for policy makers and government agencies owing to continuous rise of food prices. Notwithstanding this, food production requires adequate financing and by extension, plays some important role in reducing poverty level. Hence, this study investigates the extent to which specific agricultural financing will impact food production and reduce poverty level. The study employs secondary data which spans 1981 to 2021 and adopts Autoregressive Distributed Lag (ARDL) for the methodology. The choice of ARDL is to capture the impact for short- and long-run period. The findings from the study highlight the following: specific agricultural financing is found to be highly instrumental in promoting food production in the country. Aside this, food production is equally found to have much impact in reducing poverty level. This impact is assured in both short- and long-run periods. However, while available arable land significantly influences agricultural finance, it is much found to be sustained and long lived in the long run. Thus, the policy implication arising from this study gives necessity to a policy that will enhance credit facilities to the farmers and other supports that will ensure food surplus.
由于粮食价格持续上涨,尼日利亚对充足粮食生产的需求日益成为决策者和政府机构必须实现的目标。尽管如此,粮食生产仍需要充足的资金,进而在降低贫困水平方面发挥重要作用。因此,本研究调查了特定农业融资对粮食生产和降低贫困水平的影响程度。本研究采用了 1981 年至 2021 年的二手数据,并采用了自回归分布滞后(ARDL)方法。选择自回归分布滞后法是为了捕捉短期和长期的影响。研究结果强调了以下几点:特定农业融资在促进该国粮食生产方面发挥了重要作用。除此以外,还发现粮食生产对降低贫困水平也有很大影响。这种影响在短期和长期都得到了保证。不过,虽然可用耕地对农业融资有重大影响,但从长远来看,这种影响并不持久。因此,本研究产生的政策影响使得有必要制定一项政策,加强对农民的信贷服务和其他支持,以确保粮食过剩。

The Effects of Industrial Park Development on Export Earning, Employment and FDI Attraction: Evidence from Ethiopia 工业园区发展对出口收入、就业和吸引FDI的影响:来自埃塞俄比亚的证据
Pub Date : 2023-07-28 DOI: 10.22158/jetr.v4n2p20

This study examines the effects of industrial parks on export earnings, employment creation, and FDI attraction in Ethiopia. Furthermore, the study aims to identify the constraints and potential to achieve sustained and dynamic results expected from the industrial park development. Despite varying degrees of successes and failures, several countries have utilized industrial park and other types of special economic zones as a policy instrument for fostering economic transformation. Ethiopia is one of the African countries that have adopted industrial park development as a policy tool to enhance its economic growth and transformation. However, the effect of the industrial park policy initiative of the country is not well researched. The analysis of the study reveals that industrial parks in Ethiopia have contributed statistically significant effects on export earnings, employment creation, and FDI attraction with significant levels of p= <.001. The analysis also showed that the top five binding constraints for the effectiveness of the industrial park development are low labor productivity, domestic raw material supply constraints, weak forward and backward linkage, transport cost and logistic constraints, and institutions’ capacity constraints. On the other hand, the availability of a trainable labor force, raw material potential, preferential policies and incentives, the economic growth of the country, and the labor wage rise in China and other emerging countries are identified as the top five potentials and opportunities to achieve sustained and dynamic benefits of industrial park development in Ethiopia.
本研究考察了埃塞俄比亚工业园区对出口收入、创造就业和吸引外国直接投资的影响。此外,本研究旨在找出工业园区发展的制约因素和潜力,以达到预期的持续和动态的结果。尽管有不同程度的成功和失败,一些国家利用工业园区和其他类型的经济特区作为促进经济转型的政策工具。埃塞俄比亚是将工业园区发展作为促进经济增长和转型的政策工具的非洲国家之一。然而,国家产业园区政策举措的效果研究并不充分。研究分析表明,埃塞俄比亚工业园区对出口收入、创造就业和吸引外国直接投资的影响具有统计学意义,显著水平p= <.001。分析还表明,制约产业园区发展有效性的前五大约束性约束分别是劳动生产率低、国内原材料供应约束、前后联动弱、运输成本和物流约束、机构能力约束。另一方面,可培训劳动力的可获得性、原材料潜力、优惠政策和激励措施、国家经济增长以及中国和其他新兴国家的劳动工资上涨被确定为埃塞俄比亚工业园区发展实现持续和动态效益的五大潜力和机会。

Developing the surface transportation systems the United States needs will require asking and answering a series of questions, beginning with the most basic:What is the main purpose of surface transportation?What resources are available and what is the best way to deploy those resources?How do we measure success?Determining what future transportation systems should look like will require analyzing a range of economic, demographic, technological and socio-political variables.As management guru Peter Druker famously said, “The primary goal of every enterprise should be to create customers”. Transportation leaders must undertake the critical task of determining what transportation customers want and are willing to pay for. In doing so, they must understand that there are many categories of customers—such as commuters, businesses, and logistics companies—each with different priorities. Measurements of success should also be customer-focused.Finally, state departments of transportation—not their federal counterparts—are often best positioned to ask these questions and develop the right answers for their own states.
发展美国所需的地面运输系统需要提出并回答一系列问题,从最基本的问题开始:地面运输的主要目的是什么?有哪些可用资源,部署这些资源的最佳方式是什么?我们如何衡量成功?确定未来的交通系统应该是什么样子,需要分析一系列经济、人口、技术和社会政治变量。正如管理大师彼得·德鲁克的名言:“每个企业的首要目标都应该是创造客户”。交通运输领导者必须承担关键的任务,即确定客户想要什么样的交通运输,并愿意为之付费。在这样做的过程中,他们必须明白,有许多类别的客户——比如通勤者、企业和物流公司——每个类别都有不同的优先级。衡量成功也应该以客户为中心。最后,各州的交通部门——而不是他们的联邦部门——通常最有资格提出这些问题,并为自己的州找到正确的答案。

Sustainable Development mindset with servant leadership has been mentioned in past studies for transformations. Under covid-19, there is a need for new way of committed organizations to provide professional services, for example, business related training services with United Nations sustainable development goals (UNSDGs) and ESG (Environmental, Social and Governance). Moreover, digital art related business services may be a future area for the education sector too. It is time to explore attitudes, skills and values needed for a professional business servant leader to re-design workflow with transformations and services with innovations for driving economic growth.
在过去的转型研究中提到了可持续发展思维与仆人式领导。在2019冠状病毒病背景下,需要有承诺的组织以新的方式提供专业服务,例如,与联合国可持续发展目标(UNSDGs)和ESG(环境、社会和治理)相关的业务培训服务。此外,数字艺术相关的商业服务也可能是教育部门的未来领域。现在是时候探索一个专业的业务服务型领导者所需要的态度、技能和价值观,通过变革和服务创新来重新设计工作流程,以推动经济增长。
