The value of community technology workers for LPG use: A pilot in Shirati, Tanzania

Background Sustainable Development Goal (SDG) 7 calls for the adoption and continued use of clean-burning stoves by the 2.9 billion people relying on unclean fuels (both solid biomass and kerosene). However, to date, the clean cooking literature has found low rates of efficient stove adoption and continued use. This paper presents the application of a public health community engagement model to the use of clean cooking fuels. We implemented a pilot study with Community Technology Workers (CTWs) as a means to overcome maintenance, education, and behavioral barriers to clean fuel use in rural Tanzania. Methods The intervention was a free 6 kg Liquified Petroleum Gas (LPG) cylinder and stove coupled with education from a local technically trained CTW on LPG use. We evaluated the training, work, and impact of a CTW on LPG use on 30 randomly selected households from two villages in a rural district of Tanzania over a 1-year period. After an initial baseline survey, technically trained local CTWs educated the households on safe LPG use and conducted 34 follow up surveys over the next year on their cooking fuel use. Additionally, we conducted qualitative interviews with all households and a focus group with six of the households. Results The results from the mixed methods approach show that 80% of families (n = 24) consistently refilled their LPG cylinders and ~ 40% of households exclusively used LPG. Households reported appreciating the CTWs’ visits for providing education and maintenance support, giving them confidence to use LPG safely, reminding them to save for their cylinder, and providing a community driven effort to use clean fuel. Conclusions The findings demonstrate the feasibility of this type of community infrastructure model to promote and facilitate consistent LPG use, but suggest the need to couple this local support with financial mechanisms (e.g., a microsavings program). This model could be a mechanism to increase LPG use, particularly in rural, low-income areas.

Socio-biomedical predictors of child nutrition in India: an ecological analysis from a nationally representative Demographic and Health Survey, 2015–2016

Background Despite significant economic growth and development, undernutrition among children remains a major public health challenge for low- and middle-income countries in the twenty-first century. In Millennium Development Goals, India committed halving the prevalence of underweight children by 2015. This study aimed to explain the geographical variation in child malnutrition level and understand the socio-biomedical predictors of child nutrition in India. Methods We used the data from India’s National Family Health Survey 2015–2016. The survey provided estimates of stunting, wasting, and underweight at the national, state, and district level to measure nutritional status of under-five children. Level of stunting, wasting and underweight at the district level are considered as outcome variables. We have used variance inflation factor to check the multicollinearity between potential predictors of nutrition. In this study, we performed spatial analysis using ArcGIS and multiple linear regression analysis using Stata version 15. Results Five states (Uttar Pradesh, Bihar, Madhya Pradesh, Jharkhand and Meghalaya) had very high prevalence of stunting (40% and above). High prevalence of wasting was documented in Jharkhand, Madhya Pradesh, Chhattisgarh, and Karnataka (23 to 29%). Jharkhand, Madhya Pradesh, Maharashtra, and Chhattisgarh had the highest proportion of underweight children in the country. We found that electricity and clean fuel use in the household, use of iodized salt, and level of exclusive breastfeeding had significantly negative influence on the stunting level in the districts. The use of iodized salt has similar effect on the wasting status of under-five children in the districts (b: − 0.27, p < 0.10). Further, underweight level had a negative association with clean fuel use for cooking (b: − 0.17, p < 0.01), use of iodized salt (b: − 0.36, p < 0.10), breastfeeding within one hour (b: − 0.18, p < 0.10), semisolid/solid food within 6–8 months (b: − 0.11, p < 0.05) and Gross Domestic Product of the districts (b: − 0.53, p < 0.10). Conclusion In the study, a variety of factors including electricity and clean fuel use in the household, use of iodized salt, level of exclusive breastfeeding, breastfeeding within one hour, semisolid/solid food within 6–8 months and Gross Domestic Product of the districts have a significant association with nutritional status of children.

Cooking Fuels and Respiratory Infirmity in Rural Barak Valley: An Analysis of Pradhan Mantri Ujjwala Yojana Period

This study is an attempt to examine the fuel use pattern and its impact on the respiratory health of the users in the rural area of Barak Valley region of southern Assam. The effectiveness of Pradhan Mantri Ujjwala Yojana (PMUY) in mitigating the practice of unclean fuel has also been analysed in this study along with other related issues. The results based on personal information of 2,541 individuals from 530 households of Barak Valley reveal that incidence of respiratory illness is more profound in the households of solid biomass fuel users. The study further reveals that though PMUY has equipped the rural households with clean fuel connections but failed to change the fuel use practice of the beneficiaries. Among the barriers of clean fuel use practices, insufficient income of the households and availability of free and low-cost alternative fuels are found to be more prominent. The ordered probit model to examine the factors posing risk to respiratory illness reveal that women are at higher risk of developing respiratory syndromes as they spend more time in cooking space. While among others, smoking habit and age of the person are significant in increasing the risk pulmonary syndromes. JEL: I15, I38, Q52, Q58

Design and fabrication of solar powered bicycle

The paper focuses on the design of an electric driven bicycle that can stimulate power using solar energy and the rear wheel is provided with motor. The vehicle is being designed to house one driver; essentially, there would be need for additional space for other passengers and materials In India, the pollution rate caused by fuel-consuming vehicles is very high. It is necessary to reduce the consumption of fuel/use of fuel consumption vehicle and its hazardous emissions. The sunny weather in India lasts around 9 months, hence solar powered bicycle seems to be appropriate in India. Solar powered bicycle can become an alternative to the fuel consuming bikes and scooters.
