The Engineer’s role in addressing global poverty challenges has often been confined to village and community-scale interventions, product design and development, or large-scale infrastructure design and construction. Yet despite fifty years of these approaches, over half the world’s population still lives on less than $5.50 a day, the global burden of disease in low-income countries is overwhelmingly attributable to environmental health contaminants, and climate change is already negatively affecting people in developing countries. The conventional community, product or infrastructure focuses of development engineering is insufficient to address these global drivers that perpetuate poverty. The emerging field of Global Engineering can work to identify and address these structural issues. Global Engineering should be concerned with the unequal and unjust distribution of access to basic services such as water, sanitation, energy, food, transportation and shelter, and place an emphasis on identifying the drivers, determinants and solutions favoring equitable access. Technology development and validation, data collection and impact evaluation can contribute to evidence-based influence on policies and practice. Global Engineering envisions a world in which everyone has safe water, sanitation, energy, food, shelter and infrastructure, and can live in health, dignity, and prosperity.

The purpose of the present study was to evaluate the performance of a low-cost commercial smartwatch, the Xiaomi Mi Band (MB), in extracting physical activity and sleep-related measures and show its potential use in addressing questions that require large-scale real-time data and/or intercultural data including low-income countries. We evaluated physical activity and sleep-related measures and discussed the potential application of such devices for large-scale step and sleep data acquisition. To that end, we conducted two separate studies. In Study 1, we evaluated the performance of MB by comparing it to the GT3X (ActiGraph, wGT3X-BT), a scientific actigraph used in research, as well as subjective sleep reports. In Study 2, we distributed the MB across four countries (Austria, Germany, Cuba, and Ukraine) and investigated physical activity and sleep among these countries. The results of Study 1 indicated that MB step counts correlated highly with the scientific GT3X device, but did display biases. In addition, the MB-derived wake-up and total-sleep-times showed high agreement with subjective reports, but partly deviated from GT3X predictions. Study 2 revealed similar MB step counts across countries, but significant later wake-up and bedtimes for Ukraine than the other countries. We hope that our studies will stimulate future large-scale sensor-based physical activity and sleep research studies, including various cultures.

About 2 billion people in low-income countries are dependent upon smallholding farming for their livelihoods. These are among the world’s poorest people. Most of them lack land tenure and farm in regions with limited land and water resources. Many must cope with drought, desertification, and environmental damage caused by failed land reforms, large-scale monocropping, overgrazing, logging, destroyed watersheds, and the encroachment of new pests and diseases. They use only the most primitive of tools and they lack the knowledge and skills to improve their farming methods, value-add their produce, and compete in national and global markets. Many of these smallholder communities have been devastated by HIV/AIDS. In some regions of sub-Saharan Africa, food production has dropped by 40%, and it is estimated that over the next 20 years, 26% of the agricultural labour force will be lost to this pandemic. And demographic and economic changes in the low-income nations are increasingly leaving farming in the hands of women, who lack the knowledge and resources to farm efficiently.

The urban areas of many low-income countries must balance a rising demand for pit latrines for household sanitation provision against limitations in space, resulting in a need for pit latrine emptying services. This study was undertaken in the peri-urban neighborhood of Area 1B in the city of Mzuzu, Malawi, to examine the characteristics of household pit latrines for designing and selecting pit latrine emptying tools. We used 150 structured household surveys and field observations. From this, a subset was selected and 30 manual cone penetrometer tests were conducted at full latrines. Chemical oxygen demand analysis was also performed for 14 pit latrines. The results indicated that in addition to serving as a disposal for fecal matter, 90% of households also used pit latrines for domestic waste. Only 10% of the studied pit latrines were lined. The filling rate in the study area is calculated to be about three years, and no respondents reported previous emptying. It is suggested pit latrine emptying technology development focuses on a maximum tool diameter of 10 cm to fit through the keyhole (squat hole) and height of 146 cm to fit inside the superstructure, as well as supporting unlined pits and the ability to pump trash.

The COVID-19 outbreak was declared by the World Health Organization (WHO) as global pandemic in March 2020. Considering the necessity to implement rapid response to control the pandemic and the fragility and the state of need of low income countries, it will be mandatory to develop a global approach in order to reduce the spread of infection and the creation of community viral reservoirs. So far, we could hypothesize a worst case scenario in which when the COVID-19 outbreak hits a peak in Africa and in low-income countries, the majority of such countries will be unprepared, with low resources allocated for affording the viral emergency and the consequences will be catastrophic with no lesson learnt. In the best case scenario, the COVID-19 will not affect Africa or South America on a large scale and, if the prevention measures will be implemented, we could register a lower incidence of hygiene linked diseases that still represent leading causes of death.

The global burden of infectious diseases and the increased attention to natural, accidental, and deliberate biological threats has resulted in significant investment in infectious disease research. Translating the results of these studies to inform prevention, detection, and response efforts often can be challenging, especially if prior relationships and communications have not been established with decision-makers. Whatever scientific information is shared with decision-makers before, during, and after public health emergencies is highly dependent on the individuals or organizations who are communicating with policy-makers. This article briefly describes the landscape of stakeholders involved in information-sharing before and during emergencies. We identify critical gaps in translation of scientific expertise and results, and biosafety and biosecurity measures to public health policy and practice with a focus on One Health and zoonotic diseases. Finally, we conclude by exploring ways of improving communication and funding, both of which help to address the identified gaps. By leveraging existing scientific information (from both the natural and social sciences) in the public health decision-making process, large-scale outbreaks may be averted even in low-income countries.

BackgroundPneumonia is the largest cause of child deaths in low-income countries. Lack of availability of oxygen in small rural hospitals results in avoidable deaths and unnecessary and unsafe referrals.MethodWe evaluated a programme for improving reliable oxygen therapy using oxygen concentrators, pulse oximeters and sustainable solar power in 38 remote health facilities in nine provinces in Papua New Guinea. The programme included a quality improvement approach with training, identification of gaps, problem solving and corrective measures. Admissions and deaths from pneumonia and overall paediatric admissions, deaths and referrals were recorded using routine health information data for 2–4 years prior to the intervention and 2–4 years after. Using Poisson regression we calculated incidence rates (IRs) preintervention and postintervention, and incidence rate ratios (IRR).ResultsThere were 18 933 pneumonia admissions and 530 pneumonia deaths. Pneumonia admission numbers were significantly lower in the postintervention era than in the preintervention era. The IRs for pneumonia deaths preintervention and postintervention were 2.83 (1.98–4.06) and 1.17 (0.48–1.86) per 100 pneumonia admissions: the IRR for pneumonia deaths was 0.41 (0.24–0.71, p<0.005). There were 58 324 paediatric admissions and 2259 paediatric deaths. The IR for child deaths preintervention and postintervention were 3.22 (2.42–4.28) and 1.94 (1.23–2.65) per 100 paediatric admissions: IRR 0.60 (0.45–0.81, p<0.005). In the years postintervention period, an estimated 348 lives were saved, at a cost of US$6435 per life saved and over 1500 referrals were avoided.ConclusionsSolar-powered oxygen systems supported by continuous quality improvement can be achieved at large scale in rural and remote hospitals and health care facilities, and was associated with reduced child deaths and reduced referrals. Variability of effectiveness in different contexts calls for strengthening of quality improvement in rural health facilities.Trial registration numberACTRN12616001469404.

This paper examines whether Amartya Sen’s entitlements and capabilities concepts can be transferred in their application from low-income countries to high-income countries, specifically Cumbria, Northern England. Originally used to understand the causes of famine, these concepts have previously been used in several different geographical contexts to broadly understand poverty and inequality but almost entirely in low-income countries. This paper applies these concepts to a United Kingdom context in an attempt to understand the causes of poverty and inequality among people experiencing “livelihood crisis.” The research uses data from two nongovernmental social welfare projects to examine the causes of crisis and the remedial effects of the intervention. Our findings indicate that these concepts can help to explain how people find themselves in crisis in Cumbria. On a broader level, they can also be used to explain poverty, inequality, and disadvantage in communities in the United Kingdom. The authors put forward that entitlements and capabilities provide a useful framework to advance the policy and political debate on the causes of poverty by providing a straightforward language and broad application. Entitlement and capabilities can also assist social welfare programs in framing their aims and objectives and through improved understanding about the causes of inequality, will be better able to support people out of disadvantage by strengthening entitlements and building capabilities, without the necessity of large-scale investment.

An estimated 80% of the world's disabled people live in low-income countries. The majority of them are poor and do not have access to basic services, including rehabilitation facilities. Motivation is an international organization working in low-income countries to improve opportunities for disabled people by positively influencing their physical, social, and economic situations to enable their full participation in society. Providing good-quality, low-cost, ergonomic wheelchairs in low-income countries is extremely challenging. These complex issues are best addressed by establishing comprehensive services with trained staff and a range of innovative product solutions.

Studies from both high and low-middle income (LAMI) countries have documented how being reared in poverty is linked to compromised child development. Links between poverty and development are mediated by the timing and extent of exposure to both risk factors nested under poverty and to protective influences which can attenuate the impact of risk. While children from high-, middle-, and low-income countries are exposed to similar types of developmental risks, children from low- and middle-income countries are exposed to a greater number, more varied and more intense risks. Given these contextual differences, cumulative risk models may provide a better fit than mediated models for understanding the nature of pathways linking economic insufficiency and developmental inequality in low- and middle-income countries, and for designing interventions to promote development of children from these countries. New evidence from a large scale UNICEF data set illustrates the application of a cumulative risk/protective perspective in low- and middle-income countries.

Abstract Background The UNODC with the collaboration of the Government implemented in Nigeria a large-scale project to promote healthy lifestyles in schools, families and communities. Within the project, the prevention program Unplugged was tested through a randomized controlled trial. This study aims to evaluate the implementation of the program in the intervention schools and the satisfaction of teachers and students. Methods 32 schools were randomly extracted from a list of 60 schools provided by the Federal Ministry of Education. 16 schools were randomly allocated to intervention and implemented Unplugged. To monitor program implementation, the teachers filled a form reporting data on fidelity of implementation. To monitor satisfaction, teachers and students filled an anonymous form at the end of the program. Results 69% of intervention schools participated in the process evaluation. The duration of the units was on average 55 min. The implementation rate was very high. All classes implemented six units whilst less than 10% did not implement the other six units. The highest rate of not implementing classes was observed for unit 11 and 12. The highest student interest as declared by the teachers was observed for Unit 1 and 8, the highest interactivity for Unit 9 and 8. Most teachers found the units easy to lead and referred an improvement of teaching skills, knowledge about substances, relationship with the students and class climate, and found very useful the Teacher Handbook. Ninety percent of students considered Unplugged useful for their choices, for 82% it improved the vision of themselves, for 95% their knowledge, for 80% the relationship with mates and for 77% the relationship with teachers. 97.5% of students would like to have a similar program next year. Conclusions Unplugged reached in Nigeria very good results in terms of implementation and satisfaction of teachers and students. Process evaluation is useful to improve the quality of prevention interventions. Key messages School based prevention interventions like Unplugged can be successfully implemented in low income countries, especially when supported by printed Handbook for teachers. Teachers and students participating in Unplugged perceived an improvement of class climate and relationship between teachers and students due to the program.
