Telecommunications and Energy Infrastructure Sharing: Technical and Socio-Economic Impact Analysis in a Multi-Operator Environment in Burundi

The sharing of telecommunications infrastructure and power supply equipment is currently an applicable and very common model for grouping signal transmission and reception equipment and their power supply on the same site to ensure coverage of fixed, mobile, Internet and radio and television broadcasting networks. This study consists of producing an inventory of telecommunications and energy infrastructure sharing, focusing on the one hand on analyzing the impacts of active and passive sharing of telecommunications infrastructure from a technical point of view, particularly in terms of legal framework, deployment, coverage and exposure to electromagnetic radiation, and on the other hand on identifying the effects of infrastructure sharing from a socio-economic point of view in a multi-operator mobile telephony environment, by indicating the economic value of the revenue generated as a result of infrastructure sharing. Finally, the results will contribute to identify strategies for ensuring maximum deployment and coverage of the country, and for developing the information and communication technologies (ICT) sector in order to contribute to the digital transformation by digitising services using mobile telephony and the Internet in Burundi.

Some Reflections of the Geographies of Socio-Economic Impact of the Kosi River Floods, 2008

In India, floods remain a natural recurrent event of many major rivers of the sub-continent. Most frequently, it occurs during the ＂monsoon season＂ when precipitation remains very heavy and the natural watercourses fail to accommodate excess water. The river Kosi, located in Bihar, India too bears a long history of annual floods and is often labeled as a ＂Sorrow of Bihar＂ due to its strange behavioural attributes and the extensive damage it causes as a result of severe flood inundation. The river Kosi is one of the megafans of the Gangetic plains. Geologic evidence demonstrates that the megafans are prone to devastating flood hazards. On August 18, 2008, the river Kosi burst through its banks to flow into a channel it had abandoned more than 200 years ago, drowning towns, numerous villages and rendering over a million homeless and many were reported to have died. The research is an attempt to reflect on the geographies of socio-economic impact of the Kosi flood, 2008. For this, the research uses a holistic approach. The findings suggest that the rescue and rehabilitation operation continue in the post flood region. However, operations were significantly delayed as the result of inept bureaucratic process and insufficient funding. The final sections draw together, the threads of analysis and suggest suitable measures, so that the floods of such magnitude can be managed better in near future.

Social Determinants of Health in Understanding the Socio-Economic Impacts of Covid-19 Pandemic in Bangladesh

Social determinants of health are some indicating factors such as income, education, class, gender, and race that influence the socio-economic status of people living in a society. Coronavirus affects the social, economic, and also political sectors of people all over the world. In Bangladesh, during the Covid-19 pandemic, people of all ages and classes have faced social and economic crises based on the social determinants of health. Higher-class families had the facility of advanced medical services rather than the lower and lower-middle classes. This article aims to show the relationship between the social determinants of health and the socio-economic impact of the Covid-19 pandemic in Bangladesh. This paper presents some secondary data to describe the socio-economic impact of Covid-19 and the functions of the social determinants of health in this case.

Assessment of Socio-Economic Impacts of the December 2011 Flood Event in Dar es Salaam, Tanzania

Floods are the most devastating hazards that have significant adverse impacts on people and their livelihoods. Their impacts can be reduced by investing on: 1) improving the forecasting skills of extreme and heavy rainfall events, 2) development of Impacts Based Flood Early Warning System (IBFEWS) and 3) effective communication of impacts from anticipated extreme or heavy rainfall event. The development of IBFEWS however, requires a complete understanding of factors that relates to the formation of extreme or heavy rainfall events and their associated socio-economic impacts. This information is crucial in the development of Impacts Based Flood Forecasting Models (IBFFMs). In this study, we assess the socio-economic impacts of the December 2011 flood event in Dar es Salaam as the preliminary stage in the development of IBFFMs for the City of Dar es Salaam. Data from household survey collected using systematic random sampling techniques and structured questionnaires are used. The survey was conducted to acquire respondent’s views on the causes of floods impacts, adaptive capacity to extreme or heavy rainfall events and adaptation options to minimize flood impact. It is found that the main causes of floods were river overflow due to heavy rainfall and blocked drainage system. Poor infrastructure such as drainage and sewage systems, and ocean surge were identified to be the causes of observed impacts of the December 2011 flood event in Dar es Salaam. Death cases analysis showed that 43 people were reported dead. The flood event damaged properties worth of 7.5 million Tanzania shillings. Furthermore, the Tanzania Government spent a total amount of 1.83 billion Tanzanian shillings to rescue and relocate vulnerable communities that lived-in low-lying areas of Jagwani to high ground areas of Mabwepande in Kinondoni district.

The Socio-Economic Impact of Land Use and Land Cover Change on the Inhabitants of Mount Bambouto Caldera of the Western Highlands of Cameroon

This work assessed the impact of land use and land cover (LULC) change on the socio-economic conditions of the inhabitants in the Mount Bambouto Caldera from 1980-2016. To achieve this, three time series satellite images;Landsat Thematic Mapper (TM) (1980), Landsat Enhanced Thematic Mapper (ETM) (2001), and Landsat 8 Operational Land Imager (OLI) (2016) scenes were employed to investigate the changes in LULC. The use of satellite images was supplemented with individual interviews, discussions with focus groups and key informants, and direct field observations. Five categories of LULC classes were identified namely: thick woody vegetation (natural forest and oil palms), light vegetation (croplands), savannah (grasslands), buildings (settlements), and bare grounds. The results showed that between 1980 and 2016, croplands, buildings and bare lands increased by 4%, 0.43% and 5.7% respectively while savannah/grassland and natural forest decreased by 4.4% and 5.8% respectively. Household survey revealed soil fertility decline and lack of credit schemes to be major constraints to crop production. Many religious holidays contribute to seasonal food shortages and the community faces a host of socio-economic and institutional challenges. Consequently, majority of house-holds are destitute, live in abject poverty;which is an indication of the need for interventions by government and other development stakeholders to tackle the problems of soil fertility, land use change and food insecurity.

Brackish Shrimp Farming in Northeastern Brazil: The Environmental and Socio-Economic Impacts and Sustainability

Despite the economic importance of farmed shrimp, a number of technical, environmental, economic and social problems have been widely reported in the international literature. This paper focuses on the environmental and socio-economic impacts of semi-intensive and intensive shrimp farming in the coastal region of Northeastern Brazil and the identification of options for sustainable production. In this Region, the total area dedicated to shrimp farming is approximately 18,500 ha, of which 5750 ha are located in Ceará State. The estuary of Jaguaribe river has the largest number of shrimp farms in the state of Ceará. Currently, the industry has 64 participating farms with a total area dedicated to shrimp farming of 2411.3 ha. In 2011, the total production was 13,110 tons of shrimp with an average yield of 6330 kg ha1.year-1 in a pond area of 2071.2 ha. This industry employs 2350 people that represent 23.2% of jobs generated in the two municipalities where the Jaguaribe river estuary is inserted. Compared with other countries, Brazil has reduced its exports due to high cost inputs for shrimp farming. However, the Brazilian shrimp industry has benefited from high domestic prices, despite the decreases in international price of shrimp. In 2011, the prices for size category ranged between U$ 4.67 - 6.04 for 80/100 (count of head-on shrimp), U$ 4.95 - 6.60 for 70/80 and U$ 5.

Land Cover Change and Its Socio-Economic Impact on the Residents of the Mara River, Kenya

Anthropogenic activities are increasingly catalyzing natural climatic factors that drive land cover change at different spatial scales. Available land cover data of the Mara River basin however give a broader picture of the entire basin regardless of the heterogeneity that exists at the sub-catchment level. This study sought to establish sub-catchment specific information on land cover changes through examination of satellite images of four Mara River sub-catchments (Amala, Nyangores, Talek and Sand River) for the period 1987-2017. The relationship between temperature, rainfall and land cover was also computed. In addition, a household survey and focus group discussions were conducted in each sub-catchments to establish the socio-economic impacts of land cover change on the community’s wellbeing. Forest cover was dominant in Amala (39.8%) and Nyangores (43.7%) sub-catchments in 1987 but by 2017 crop lands had surpassed forest cover in the two sub-catchments, accounting for 53.2% and 45.7%, respectively. However, in Talek (52.8%) and Sand River (47.4%) sub-catchments, grassland was the dominant land cover type in 1987 and after the 30 year period, grasslands remained dominant in Sand River, while shrub land became dominant in Talek sub-catchment. A weak positive correlation was observed between rainfall and forest cover, shrub land and cropland, while a negative correlation was observed between rainfall and bare land. Average temperature showed a positive moderate correlation with bare land and built up areas. Analysis of survey data revealed that livestock keeping, temperature increase, type of trees, education level of household head and weak environmental laws were the main drivers of land cover change (P −0.587), beans (r = −0.5459), sorghum (r = −0.351), cow peas (r = −0.544), and pigeon peas (r = −0.337). Focus group discussions participants were supportive of environmental protective measures to reverse negative land cover changes, while planting drought resistant trees, crop diversification and awareness creation among community members were recommended as the most ideal environmental management strategies.

Socio-Economic Impacts of Flooding on the Residents of Port Harcourt Metropolis in Rivers State, Nigeria

Floods are naturally occurring phenomena that are part of the physical and biological process which have shaped our nation’s landscape. It occurs in Nigeria environment when there is heavy rain fall for prolonged period of time. The data collection for this research was by use of primary and secondary information;questionnaire was administered by face to face interviews and key informant surveys. Analytical technique was the univariate statistical methods. The results revealed that there is clear evidence of damages to properties and that there are hazards and risks faced by these households as shown in Tables 1-4 respectively. Table 3 specifically shows the financial losses incurred annually by residents to the tune 5 million naira and above. However, the continued hazards and risks as a result of flood incidence have affected their overall income which hitherto is found within (N20000.00 - N25000.00) about 22.8% of the respondents fall in this income bracket. Furthermore, the research also revealed that about 30% say the flood has affected their income, while 29.4% say their buildings are affected. Also about 37.8% of respondents say that the flood incidence occurs all through the rainy season. The research recommends an aggressive review of the Port Harcourt Master Plan and the implementation of the development control tools in the 1992 Urban and Regional Planning Law.

The Socio-Economic Impacts of Aged-Dam Removal: A Review

Water storage dams worldwide are ageing, and many will reach the end of their designed lifespan by the middle of the 21st century. Some of these dams will likely need to be removed. While dam construction impacts have been widely discussed, dam removal impacts on society and the economy need to be synthesized and considered in the ageing dams’ decision-making process. This paper summarizes dam removal impacts on the local economy and industry, culture, history and heritage, property value, recreation, aesthetics, and disaster avoidance from identified studies worldwide. It demonstrates that these impacts may vary depending on geography and between developed and developing countries. It concludes that dam removal should consider the cost, environmental, and the socio-economic impacts while including all stakeholders who could be positively and negatively impacted by dam removal.

Ulcero-Necrotic Wound: Socio-Economic Impact, Kayes, Mali

The issue of wound care has always played an important role in the practice of medicine. This is evidenced by Ambroise Paré’s decision to publish his first work on this subject, “La manière de traiter les Plaies” (The Way of Treating Wounds) in 1545. Objective: To evaluate the therapeutic methods we practice and to describe the impact of the pathology on socio-economic and professional development. Patients and Method: This was a retrospective study carried out at the Fousseyni Daou Hospital in Kayes from January 1, 2018, to December 31, 2020. We included all patients with an ulcero-necrotic wound on immunocompetent terrain hospitalized in the department. Patients with ulcerative necrotic wounds of diabetes, HIV, or cancerous origin were not included. The parameters studied were: etiologies, local care, sequelae, and socio-economic and professional aspects. Results: We collected 57 patients of whom 43 were men and 14 were women, i.e. a sex ratio of 3. The mean age was 40.7 years with a standard deviation of 8.4 with extremes (7 years and 80 years). The average consultation time was 25.1 days. The most represented socio-professional stratum was agropastoralism in 37 cases (65%). The predominant etiological factor was neglected traumatic wounds in 34 cases (59.6%). The site was the lower limb in 39 cases (68.5%). The germ found was Staphylococcus aureus in 21 cases (36.8%). The particularity during local care was the use of table sugar in 9 cases (15.7%) and maggot therapy in 2 cases (3.5%). Hyperthermia was the clinical sign of aggravation in 22 cases (38.6%) and we diagnosed 2 cases (3.5%) of tetanus. The mortality rate was 15.7% (9 cases) and 30 cases (52.7%) of sequelae after recovery. The average length of hospitalization was 38 days. Hospital care was provided by the social welfare service in 35 cases (61.4%). Nineteen (19) patients (39.5%) were unable to resume their socio-professional activity. Conclusion: Ulcero-necrotic wounds are complex to manage and can have a lifelong influence on the socio-professional and economic activity of patients.

Socio-Economic Impacts of Primary Open-Angle Glaucoma in Rural Environment in Mali

Primary open-angle glaucoma (POAG) is an optic neuropathy that affects the patient’s quality of life. The present study aims to write the socio-economic factors influencing the management of glaucomatous patients in rural areas. This was a retrospective, descriptive cross-sectional study, carried out from October 19 to 31, 2017 in a rural town. The variables studied were age, sex, occupation, level of knowledge about the disease and its treatment, average monthly income, accessibility of eye care service, health insurance membership, degree of severity of the disease. The frequency of POAG was 5.68%. The average age of the patients was 52 years old with extremes ranging from 25 to 73 years old;the female sex was the most represented with 19 cases out of 36 or 52.77%. 66.67% of our patients were at their first ophthalmological consultations. Health insurance coverage was 2.78%. The average monthly income was 10,000 to 25,000 FCFA in 58.33%. More than half of our glaucomatous patients, 63.89%, think they are affected by their disease. 80% of patients are unaware that they have eye disease. Many lost vision in one or both eyes and were unaware of the disease affecting their eyes. Accessibility to health services and their costs seem to be a factor, in addition to illiteracy.

Socio-Economic Impacts of Tourism in Axum Town, Tigray Regional State, Ethiopia

This research paper tries to assess the multi-dimensional impacts of tourism in Axum which increases from time to time as the tourist flow increases, identifying problems which hindered the tourism environment and examining the magnitude of the multi-dimensional linkages between tourism and the local community. The main objective of the study is to understand the socio-economic impact of tourism. To achieve the objective, the researcher designed a proper methodology which includes both primary and secondary data. The primary data were collected through questionnaires, key informant interview （KII）, focus group discussion （FGD）, and observations from 208 total respondents. To support the primary data, secondary data were also collected and were all analyzed both qualitatively and quantitatively. As the finding indicates, tourism has a multi-dimensional impact, economically, socio-culturally, environmentally as well as politically. For instance, the positive contributions of tourism are： source of employment for 2,389 people and the number of employed workers in business household heads （HHs） also increases by 11% every year, similarly the income of business HHs also increases by 8.8% every year as the tourist flow increases. Similar to economic impact, the sector has also socio-cultural, environmental, and political importance such as infrastructural improvement, preservation of attractions, creating environmental awareness, and encouraging power and librating effect of women which are few among the positive impacts. On the contrary, the sector has also negative impacts in terms of motivating begging and dependence, seasonal unemployment and unstable income, aggravating prostitution and student dropout, loss of cultural identity, environmental and heritage degradation and taking of intelligence, which are few among the negative one but the positive impact of tourism outweighs the negative one. Even though the sector has its own contribdtion in the town in a multi-dimensional way, the town cannot gain from the sector as its potential of attraction endowment due to poor infrastructure and accommodation provision, social-related problems such as begging, theft and high entrance fee of attractions, inadequacy in quality and quantity service pervasion, lack of awareness and promotional works, lack of coordination as well as geographical location which are among the few factors for the underdevelopment of the sector in the town. Finally, this paper recommended that participation and coordination of all concerned bodies and stakeholders should be very imperative in supporting and expansion of infrastructures which helps to increase tourist flow and income earned from it and its consequences to socio-economic benefits by giving higher attention to minimizing the negative impacts.

National Social Investment Programmes in Nigeria:A Descriptive Analysis of the Socio-Economic Contributions of N-Power Programme in Benue State

This study analysed the socio-economic contributions of N-Power programme amongst the beneficiaries of the scheme in Benue State.Prior to the introduction of N-Power programme,successive administrations in Nigeria have made concerted efforts towards improving the standard of living of the citizenry through the execution of various welfare or social intervention programmes,but not much successes were recorded.Learning from the mistakes of the past regimes,and by way of deliberate state policy,the Buhari’s government initiated a multi-pronged social investment policy,one of which is the N-power programme that came onboard in 2016,which also doubles as the subject of this study.To achieve the goal of this study,a combination of desktop research and survey design was employed.Questionnaires were administered to 390 respondents through a combination of stratified and random sampling techniques.The results of the survey were matched with that of the secondary data obtained through online websites and other related sources.The result indicated that N-Power made positive contributions to the socio-economic life of the beneficiaries in Benue State:specifically,the scheme contributed in poverty eradication,employment generation,skills acquisitions and capacity building.However,some aspect of our findings revealed that the programme has a number of challenges such as:inadequate cash support,delay in monthly cash transfer to beneficiaries,distance participants had to move to their work stations,absence of posting in N-Teach scheme,and lack of adequate working tools amongst others.To salvage this problem the paper recommended the following solutions:expansion of the scheme to cover N-Teach and other aspects,increment in the monthly cash transfer to cushion the high rate of inflation,support for the participants/beneficiaries in transportation and logistics,enrolment of more youth into the various schemes,proper monitoring and evaluation of the implementation of the schemes amongst others.

Go-Ahead Element of Domestic Architecture:Socio-Economic and Cultural Characteristics of the Residents in Benin

The domestic architecture of a traditional settlement is greatly influenced by the socio-economic and socio-cultural characteristics of its residents.Benin City which is the focus of the paper is a case of a traditional settlement undergoing domestic architectural evolution with the changing times influenced by factors of growth and development.The paper has examined the effect of socio-economic and socio-cultural characteristics as factors that partly determine the design,style,pattern,space use,organization,location and meaning as well as land use of the domestic architecture of Benin.The study employed the use of questionnaire administered to residents across the cross-section of the city.In the end,descriptive frequency tables were used to analyse the data collected from the residential zones in Benin.The research has been able to corroborate the theory that socio-economic and socio-cultural factors are some of the determinants/elements of domestic architecture of a people.

Socio-Economic Impact Assessment of Intelligent Transport Systems

A general review of the socio-economic impact of the intelligent transport system （ITS） is presented with a case study to demonstrate the data envelopment analysis method. Cost-benefit analyses are still the dominant method for evaluating ITS and other transport engineering projects, while cost effective analyses and multi-criteria appraisals are widely used to define and prioritize objectives by providing useful information for the most promising policy decisions. Both cost-benefit analyses and a data envelopment analysis method are applied to analyze the socio-economic impact of convoy driving systems. The main findings are that a convoy provides a worthwhile benefit-cost ratio when more than 30% of the traffics in the convoys and the traffic load exceeds 5500 vehicles/h for a three-lane motorway. The results also show that for a fixed percentage of convoys, increased demand will increase the data envelopment analysis method relative efficiency and that the neglect of certain output indicators of an ITS may result in underestimation of the system effects.

Effects of projectile parameters on the momentum transfer and projectile melting during hypervelocity impact

The effects of projectile/target impedance matching and projectile shape on energy,momentum transfer and projectile melting during collisions are investigated by numerical simulation.By comparing the computation results with the experimental results,the correctness of the calculation and the statistical method of momentum transfer coefficient is verified.Different shapes of aluminum,copper and heavy tungsten alloy projectiles striking aluminum,basalt,and pumice target for impacts up to 10 km/s are simulated.The influence mechanism of the shape of the projectile and projectile/target density on the momentum transfer was obtained.With an increase in projectile density and length-diameter ratio,the energy transfer time between the projectile and targets is prolonged.The projectile decelerates slowly,resulting in a larger cratering depth.The energy consumed by the projectile in the excavation stage increased,resulting in lower mass-velocity of ejecta and momentum transfer coefficient.The numerical simulation results demonstrated that for different projectile/target combinations,the higher the wave impedance of the projectile,the higher the initial phase transition velocity and the smaller the mass of phase transition.The results can provide theoretical guidance for kinetic impactor design and material selection.

The impact of demographic dynamics on food consumption and its environmental outcomes:Evidence from China

With increasing population and changing demographics,food consumption has experienced a significant transition in quantity and quality.However,a dearth of knowledge remains regarding its environmental impacts and how it responds to demographic dynamics,particularly in emerging economies like China.Using the two-stage Quadratic Almost Demand System(QUAIDS)model,this study empirically examines the impact of demographic dynamics on food consumption and its environmental outcomes based on the provincial data from 2000 to 2020 in China.Under various scenarios,according to changes in demographics,we extend our analysis to project the long-term trend of food consumption and its environmental impacts,including greenhouse gas(GHG)emissions,water footprint(WF),and land appropriation(LA).The results reveal that an increase in the proportion of senior people significantly decreases the consumption of grain and livestock meat and increases the consumption of poultry,egg,and aquatic products,particularly for urban residents.Moreover,an increase in the proportion of males in the population leads to higher consumption of poultry and aquatic products.Correspondingly,in the current scenario of an increased aging population and sex ratio,it is anticipated that GHG emissions,WF,and LA are likely to decrease by 1.37,2.52,and 3.56%,respectively.More importantly,in the scenario adhering to the standards of nutritional intake according to the Dietary Guidelines for Chinese Residents in 2022,GHG emissions,WF,and LA in urban areas would increase by 12.78,20.94,and 18.32%,respectively.Our findings suggest that changing demographics should be considered when designing policies to mitigate the diet-environment-health trilemma and achieve sustainable food consumption.
