The objective of this work is to contribute to energy justice in rural areas in Togo by promoting entrepreneurship based on the productive use of energy. To this end, in 2019 we conducted surveys of 650 rural households spread across the five economic regions of Togo. The data were collected with CSPro 6.3 software, cleaned with STATA software and analyzed with Microsoft Office EXCEL 2013 software. Based on the results obtained, three electricity supply scenarios for a rural wet coffee processing company, envisaged in the plateau region, were simulated with the HOMER Pro 3.14.4 software. The results of the surveys show that only 16% of households are connected to the electricity grid and therefore indicate to develop the available energy resources expressed, namely solar (80.9%), biomass (68.9%), water sources (47.1%) and agricultural residues (44.5%). Respondents, 64.77% of whom work in agriculture and breeding, expressed the need for the use of productive electrical equipment. The best-case scenario simulated, a mini-grid supplying the wet coffee processing company and households, revealed a levelized cost of electricity of XOF 394/kWh; lower than the cost of electrification of the company, XOF 814/kWh or that of households, XOF 488/kWh. However, this cost must be further reduced if energy is to be financially accessible to rural populations. To validate this concept, two other rural entrepreneurial initiatives will be simulated in two different agro-ecological zones of Togo

AbstractThe compelling need to tackle climate change is well-established. It is a challenge which is being faced by all nations. This requires an approach which is truly inter-disciplinary in nature, drawing on the expertise of politicians, social scientists, and technologists. We report how the pace of the energy transition can be influenced significantly by both the operation of societal barriers, and by policy actions aimed at reducing these effects. Using the case study of South Africa, a suite of interviews has been conducted with diverse energy interests, to develop and analyse four key issues pertinent to the energy transition there. We do so primarily through the lens of delivering energy justice to that society. In doing so, we emphasise the need to monitor, model, and modify the dynamic characteristic of the energy transition process and the delivery of energy justice; a static approach which ignores the fluid nature of transition will be insufficient. We conclude that the South African fossil fuel industry is still impeding the development of the country’s renewable resources, and the price of doing so is being met by those living in townships and in rural areas.

AbstractObjective:To model the potential impact and equity impact of fortifying rice on nutritional adequacy of different subpopulations in Nepal.Design:Using 24-h dietary recall data and a household consumption survey, we estimated: rice intakes; probability of adequacy (PA) of eight micronutrients commonly fortified in rice (vitamin A, niacin (B3), pyridoxine (B6), cobalamin (B12), thiamin (B1), folate (B9), Fe and Zn) plus riboflavin (B2), vitamin C and Ca and mean probability of adequacy (MPA) of these micronutrients. We modelled: no fortification; fortification of purchased rice, averaged across all households and in rice-buying households only. We compared adequacy increases between population subgroups.Setting:(i) Dhanusha and Mahottari districts of Nepal (24-h recall) and (ii) all agro-ecological zones of Nepal (consumption data).Participants:(i) Pregnant women (n 128), mothers-in-law and male household heads; (ii) households (n 4360).Results:Unfortified diets were especially inadequate in vitamins B12, A, B9, Zn and Fe. Fortification of purchased rice in rice-purchasing households increased PA > 0·9 for thiamin, niacin, B6, folate and Zn, but B12 and Fe remained inadequate even after fortification (PA range 0·3–0·9). Pregnant women’s increases exceeded men’s for thiamin, niacin, B6, folate and MPA; men had larger gains in vitamin A, B12 and Zn. Adequacy improved more in the hills (coefficient 0·08 (95 % CI 0·05, 0·10)) and mountains (coefficient 0·07 (95 % CI 0·01, 0·14)) but less in rural areas (coefficient −0·05 (95 % CI −0·09, −0·01)).Conclusions:Consumption of purchased fortified rice improves adequacy and gender equity of nutrient intake, especially in non-rice-growing areas.

Several Western Balkan states face the consequences of the Yugoslavian war, which left hometowns with dilapidated electricity grid connections, a high average age of power plant capacities and low integration of renewable energy sources, grid bottlenecks and a lack of competition. In order to supply all households with electricity, UNDP Croatia did a research on decentralized supply systems based on renewable energy sources. Decentralized supply systems offer cheaper electricity connections and provide faster support to rural development. This paper proposes a developed methodology to financially compare isolated grid solutions that primarily use renewable energies to an extension of the public electricity network to small regions in Croatia. Isolated grid supply proves to be very often a preferable option. Furthermore, it points out the lack of a reliable evaluation of non-monetizable aspects and promotes a new interdisciplinary approach.

Abstract A nonmedical switch policy is currently being considered in Alberta, which would force patients on originator biologics to biosimilar alternatives with the hypothetical aim of reducing costs to the health care system. The evidence to support the safety of nonmedical switching in patients with inflammatory bowel disease (IBD) is of low to very low quality; in fact, existing data suggest a potential risk of harm. In a pooled analysis of randomized controlled trials, one patient would lose response to infliximab for every 11 patients undergoing nonmedical switching. Switching to a biosimilar has important logistical and ethical implications including potential forced treatment changes without appropriate patient consent and unfairly penalizing patients living in rural areas and those without private drug insurance. Even in the best-case scenario, assuming perfectly executed switching without logistical delays, we predict switching 2,000 patients with Remicade will lead to over 60 avoidable surgeries in Alberta. Furthermore, nonmedical switching has not been adequately studied in vulnerable populations such as children, pregnant women, and elderly patients. While the crux of the argument for nonmedical switching is cost savings, biosimilar switching may not be cost effective: Particularly when originator therapies are being offered at the same price as biosimilars. Canadian patients with IBD have been surveyed, and their response is clear: They are not in support of nonmedical switching. Policies that directly influence patient health need to consider patient perspectives. Solutions to improve cost efficiency in health care exist but open, transparent collaboration between all involved stakeholders is required.

The Portuguese population is aging at an increasing rate, which introduces new problems, particularly in rural areas, where the population is small and widely spread throughout the territory. These people, mostly elderly, have low income and are often isolated and socially excluded. This work researches and proposes an affordable Ambient Assisted Living (AAL)-based solution to monitor the activities of elderly individuals, inside their homes, in a pervasive and non-intrusive way, while preserving their privacy. The solution uses a set of low-cost IoT sensor devices, computer vision algorithms and reasoning rules, to acquire data and recognize the activities performed by a subject inside a home. A conceptual architecture and a functional prototype were developed, the prototype being successfully tested in an environment similar to a real case scenario. The system and the underlying concept can be used as a building block for remote and distributed elderly care services, in which the elderly live autonomously in their homes, but have the attention of a caregiver when needed.

Abstract Background: Vector control is the main intervention to control arboviral diseases transmitted by Aedes mosquitoes because for most there are no effective vaccines or treatment. This vector control relies heavily on the use of insecticides, effectiveness of which may be impacted by resistance. In addition, rational insecticide application requires detailed knowledge of vector distribution, dynamics, resting, and feeding behaviours, which are poorly understood for Aedes vectors in Africa. This study investigated the spatio-temporal distribution and insecticide resistance status of Ae. aegypti from across ecological extremes of GhanaMethods: Immature mosquitoes were sampled from containers in and around human dwellings at each of seven study sites in urban, suburban, and rural areas of Ghana. Adult Aedes mosquitoes were sampled indoor and outdoor using Biogent sentinel-2 mosquito traps, human landing catches, and prokopack aspiration. Distributions of immatures and adult Aedes mosquitoes were determined indoors and outdoors during dry and rainy seasons at all sites. Phenotypic resistance status of Aedes mosquitoes to insecticides was determined using WHO bioassays. Host blood meal source was determined by PCR.Results: A total of 16,711 immature Aedes were sampled, with over 70% found in car tires. Significantly more breeding containers had Aedes immatures during the rainy season 70.95% (11,856) compared to the dry season 29.05% (4,855). A total of 1,895 adult Aedes mosquitos were collected, including Ae. aegypti (97.8%), Ae. africanus (2.1%) and Ae. Luteocephalus (0.1%). Indoor sampling of adult Aedes mosquitoes yielded a total of 381 (20.1%) and outdoor a total of 1,514 (79.9%) (z = -5.427; p = 0.0000) over the entire sampling period. Aedes aegypti populations were resistant to DDT at all study sites. Vectors showed suspected resistance to Bendiocarb (96-97%), Permethrin (90-96%) and Deltamethrin (91-96%) and were susceptible to the organophosphate malathion from all study sites.Blood meal analysis showed that the Aedes mosquitoes were mostly anthropophilic with HBI of 0.9 i.e. [(human = 90%), (human and dog = 5%), (dog and cow = 5%)].Conclusion: Aedes mosquitoes were found at high densities in all ecological zones of Ghana. Resistance to pyrethroids and carbamates may limit control efficacy and requires careful monitoring.

The Nigerian indigenous chickens (NICs) are a critical component of the global animal genetic resources. They are distributed in rural areas, kept by the majority of the rural poor. They constitute different strains, or ecotypes local to tribes, regions, or ecological zones and are valued for their disease resistance, adaptation, and yield of valuable products and income on marginal inputs making them a low risk species. They are hence a unique and vital genetic resource and gene pool for present and long-term genetic improvement and human need for food and sustenance. The NIC is however; threatened by extinction owing to neglect, negative selection, breed substitution, and genetic introgression. There is need to draw research and policy attention to the conservation of NICs in accord with the global effort for the conservation of indigenous chickens which is probably the most neglected among farm animal species. The present review therefore, focuses on the physical and performance characteristics, genetic diversity and improvement, utilization and conservation of NIC genetic resources.

Learning outcomes The learning outcomes are that at the end of the case discussion, the students should be able to evaluate the drivers of social innovation in an African context; discuss social entrepreneurship as a process-driven set of activities; assess the organisation–environment–opportunity fit when innovating; analyse and resolve practical issues in developing simple and affordable social innovations; appreciate how social enterprises are mission-based businesses rather than charities; and evaluate how an organisation may achieve social objectives and remain sustainable. Case overview/synopsis SolarTurtle is an award-winning South African social enterprise that manufactures and supplies secure, mobile, solar power stations and kiosks to communities where the electricity grid does not reach. The company converts shipping containers into housings for solar panels to protect them from theft and extreme weather conditions. These units are called “PowerTurtles”. Through the franchise model, the company supplies PowerTurtles to off-grid institutions in rural areas. PowerTurtles are also sold to private sector enterprises and are scalable to suit the energy needs of customers. With the successful launch of the AutoTurtle in 2018 (which folds away the solar panels automatically, where the PowerTurtle requires them to be folded away manually), the company started to develop a new lightweight, fibreglass, solar kiosk with roof-mounted solar panels called the MiniTurtle, and a mobile trolley version known as the BabyTurtle. Now, in 2018, Van der Walt hopes to develop the business to the point where it can sustain itself.

Providing energy to areas isolated from the electricity grid through the use of a smart integrated renewable energy system (SIRES) is proposed in this study for Valparaiso, Chile. The study analyzes the process of identifying the appropriate size of a SIRES considering technical and economic factors. An optimization model proposed in the literature was modified, and a subsequent spatial–temporal analysis of the different variables was conducted. The model comprises locally available renewable energy resources, such as biomass, biogas, wind power, solar photovoltaic, and thermal power. Furthermore, it was used to determine the energy potential of each of the isolated areas, identifying those areas in which the SIRES could be implemented as a sustainable solution. The design simulates the cost of the initial investment and energy generation in the chosen areas. The study also includes the selection of different system components and the use of the general model to determine the optimal combination of energy subsystems for isolated areas with the aim of minimizing the cost of energy generations. Finally, an economic evaluation showed that the use of a SIRES based mainly on solar energy supported by biomass, biogas, and mini-wind power costs approximately three times less than extending the electricity grid network.

Modern renewable energy is an important tool to achieve socio-economic transformation, particularly in rural areas of developing countries like Ethiopia. However, most people do not access modern energy and thus providing it is one of the daunting tasks that the government has faced. Knowing energy choice of households is one of the important factors to bring energy transition. However, limited studies are undertaken in the Country on this area. Thus, this paper tried to address the gap by investigating factors affecting households lighting energy choice by taking sample of 442 households in Mida Oromo and Wonisho Districts of Ethiopia. Both descriptive and inferential statistics were employed for analyzing the data. The result shows that households consume a range of traditional, transitional and modern lighting energy sources available in their areas. Wealthy households prefer lighting energy sources that are clean and relatively expensive including, grid electricity and solar energy unlike households in lower income category who opt to cheap and easily available energy sources. The study further highlighted that income is not the only factor affecting household energy transitions. Family size, access to market and road infrastructure, asset of the household and the district of the households, mobile and radio ownership and education attainment of the head or family members are found to be an important determinants affecting energy transition of rural households. The study concluded that any program that aim to provide modern lighting energy sources need to consider all these diverse factors and local contexts.
