Nigeria has experienced severe farmers-herders conflict that has negatively influenced her agricultural production capacity, resulting in severe food insecurity. Tensions have grown over the past decades, with increasingly violent flare-ups between the farmers and the herdsmen spreading across the entire country. In recent times, many scholarly studies and inquiries on the impact of Information Communications Technology, particularly with respect to promoting food security in Nigeria, have been engendered mainly by the need to ensure greater agricultural outputs among farmers and other agriculturists. However, only scanty attention had been devoted to the need to understand the imperativeness of the use of Information Communications Technology in the quest to proffer solutions to the incessant farmers-herdsmen conflicts that have also contributed to the unpalatable state of food security in Nigeria. The study adopts Karl Marx’s Conflict Theory as a framework of analysis and qualitative date elicited through content analysis of desktop date. Hinging on this theory, this study contends that the farmers-herdsmen conflict is inevitable like every other conflict due to the competition for limited land resources. The study however found out that why the farmers-herdsmen conflict has persisted, among many other factors, was due to the failure of relevant stakeholders to leverage on the possibilities of Information Communications Technology to address the technological gap in the conflict. While further findings suggest that the principal causes and aggravating factors behind the escalating conflict are climatic changes; population growth; technological and economic changes; crime; political and ethnic strife; and cultural changes, the lack of use of Information Communications Technology in the areas of educating both the farmers and herders, awareness creation, crime reporting and conflicts resolution further compounds the farmers-herdsmen conflicts. This study recommends the need for proper and improved use of I.C.T. in the processes to address the farmers-herdsmen conflicts.","PeriodicalId":385880,"journal":{"name":"Journal of Digital Food, Energy & Water Systems","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128788897","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 objectives of the study were to establish the relationship between the prepaid metering system and customer satisfaction; and to evaluate the level of satisfaction with respect to the usage of the prepaid metering system in Niger State, Nigeria. In carrying out the study, the structured questionnaire was administered to 393 randomly chosen respondents drawn from prepaid meter users, out of which 344 responded generating a response rate of 87.5%. The data derived were subjected to spearman correlation and multiple regression models. The major findings from the study showed a significant, moderate and positive relationship between the prepaid metering system and customer satisfaction. Additionally, three significant predictors, Affordability, Availability and Flexibility with p < .01 are statistically significant. Further findings from descriptive statistics revealed that users had the highest level of satisfaction with the privacy they had as a result of no meter readers and no accumulated. The study concluded that there exist a positive and beneficial link between the prepaid metering system and customer satisfaction. The study therefore recommends the provision of a smart metering system, good customer care units and a marketing campaign for better knowledge of the prepaid metering system.","PeriodicalId":385880,"journal":{"name":"Journal of Digital Food, Energy & Water Systems","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131841809","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 aim of the study is primarily to assess the awareness of AI in facility management, and to identify the prospects and challenges of the adoption of AI in the energy sector. The study adopted the quantitative methodology approach, using a structured questionnaire to a sample size of 384 respondents. The questionnaire was administered to professionals such as mechanical, civil, electrical, computer, and mechatronics engineers, and project managers within the North-central geopolitical zone of Nigeria. Data gathered was analysed using descriptive analysis (mean value, weighted total, and relative importance index). The study based on findings concludes that there exists high awareness level about the concept of AI in the energy sector. However, regarding the awareness about some selected AI technologies, machine & deep learning, robotics, and speech recognition had high awareness level. The study also concludes that improved energy management, efficiency and transparency, remote reading of energy meters, and improved planning, operation & control of power systems were prevalent prospects of AI adoption. The major challenging factors to the adoption of AI in the Nigerian energy sector are outdated power system infrastructure, cellular technologies, lack of qualified experts and data science skills, and growing threat from cyber-attacks. The study recommends improved awareness and technical know-how of energy sector personnel, and provision of adequate power system infrastructure to provide stable power supply.","PeriodicalId":385880,"journal":{"name":"Journal of Digital Food, Energy & Water Systems","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121751793","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}

Agricultural practices in the country are still mainly based on conventional, traditional methods of farming which usually results in wastage of water resources and low production of crops to meet the country's demand. There is a need to transform farming from the traditional way to a more efficient method with optimum water utilization. Irrigation is an assistive measure to salvage the problem of inadequate water for dry season farming. Irrigation consumes a lot of water, time and must be done on a timely basis. The automated irrigation system helps to curb the problem of overwatering and under watering of the land. This research proposed an Arduino-based smart irrigation system using a wireless sensor network to overcome the problem of overwatering, underwatering, and efficient time utilization in farming. The system is implemented using Arduino IDE, Proteus Simulation Tools, and Blynk Platform. The effect of the four-mobile network: MTN, GLO, Airtel and 9mobile on response time for Gidan- Kwano area was evaluated. Testing carried out on the system resulted in a response time of 0.75 seconds for Glo 2G network and 0.45 seconds for Glo 4G network. Less than 1sec in the worst-case scenario. This makes the system effective in terms of time response, thereby eradicate the waste of time that manual system operation poised to irrigation scheduling. Also, the appropriate soil moisture content is maintained, whether it rains or not. This reduces excesses and ensures healthy plant growth, increasing agricultural productivity, and cultivating crops are made possible throughout the year. The system also will help in driving agricultural innovation through the use of IoT. \u0000 ","PeriodicalId":385880,"journal":{"name":"Journal of Digital Food, Energy & Water Systems","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122320751","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}

Nigeria was used as a case study and an observed climatic dataset was obtained and used alongside collected 20 year cassava, rice and soybean yield data to develop models that were applied to estimate future crop yield. Four statistically downscaled and bias-corrected Global Climate Models (GCMs): NOAA, MIROC5, ICHEC, and NCC performed simulations for the period 1985–2100 under the Representative Concentration Pathway RCP8.5. These were used to predict how the yields of cassava, rice and soybean will be in the years 2020-2050 and 2070-2100 for the 36 states in Nigeria and the FCT. 89 Empirical models were developed to estimate the yields of the three crops earlier mentioned across Nigeria with their coefficient of determination (R2) ranging between 15% - 99%. The result showed an increase of 3.91% (P<0.001), 0.08, 1.79 (P<0.1) and a decrease of 0.93% for cassava yield for ICHEC, MIROC, NOAA and NCC respectively.

Energy generation from fossil fuels is not sustainable and leads to global warming, which is detrimental to the environment. This study seeks to establish how renewable energies are embedded and utilised in the Ghanaian energy system and the factors that can expedite the speedy penetration of renewable technologies into the country, particularly solar PV, wind, and biogas. The study adopted a mixed research approach which includes quantitative and qualitative studies. The findings revealed that solar energy is the most available resource in the country compared to other renewables. It was also indicative that integrating solar PV, wind and biogas in the national electricity grid will improve the percentage of energy generation mix, which will help sustain constant power supply, reduce the cost of energy charges, and consequently improve the country’s economy. The results also showed the possible factors that affect future penetration of these technologies, including unavailability of consumer financing opportunities, inadequate training facilities, lack of adequate regulations/policies, lack of information on the cost and benefits of renewable energies. The six findings of the paper established the availability of renewables in Ghana and the prospect of their related technology. While solar PV is on the ascendency, biogas is progressing gradually and wind is moving at a snail’s pace. This study significantly established the benefits of incorporating solar PV, wind and biogas in the Ghanaian energy mix to improve the electricity supply and further outlined the impeding factors that need to be improved upon through policy.","PeriodicalId":385880,"journal":{"name":"Journal of Digital Food, Energy & Water Systems","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122613223","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}

Intervention measures to reduce the risk of water shortages now and the near future are urgently needed. This can possibly be attained through the diversification of water sources and the application of smart or digital technologies to reduce water wastage.  Meaning that, cities which are at risk of water scarcity may consider a variety of alternative means, which includes smart technologies and efficient use of recycled water to meet the ever-increasing demand.  In this study the status of water security and sanitation in two inland cities (i.e. Mbombela (Nelspruit) and Polokwane (Pietersburg)) was investigated.  A gap between supply and demand for water to households was found to be large. The primary demand for water derives from households that are connected to the municipal reticulation system and used for drinking and sanitation.  Water security concerns were found to be from households in need of water supply and unmeasured demands from informal settlements that are illegally connected to the system. The uncertain nature of water availability due to climate change meant that the risk of water insecurity in studied cities was high. To ameliorate this, municipalities need to adopt new ways of managing water.  This may include the use of digital technologies and the promotion of harvesting rainwater as an alternative source.  Maintenance of existing infrastructure is highly recommended to improve efficiencies in water usage.  Overall, results reflect the high risk of water security in Mbombela and Polokwane. Of great concern is the need to manage water to improve the efficiency of its use to meet the ever-increasing demand.","PeriodicalId":385880,"journal":{"name":"Journal of Digital Food, Energy & Water Systems","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2020-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131077470","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}
