Fig. . Estimated mortality for scenarios of household energy futures in SSA. Diseases included are LRIs among children < years of age and COPD among adult women. Estimates account for forecasted demographic change (population growth and aging) and secular trends in background disease and mortality levels. The observed secular (BAU) decline in childhood LRI mortality is a result of factors such as increased coverage and efficacy of pneumonia case management using antibiotics; increased awareness and practice of breastfeeding, which increases child immunity and survival; and other secular trends caused by economic and technological factors (9). Secular (BAU) trends in COPD are upward mainly because of population aging (COPD mortality increases with age). There has been a slight increase in age-specific COPD mortality rates at older ages, possibly due to small increases in smoking among women in Africa, and a slight decrease in age-specific rates in middle ages, possibly due to competing causes of death (mainly human immunodeficiency virus/acquired immunodeficiency syndrome). Similar directions are seen for lung cancer, another disease affected by smoking, which is the main driver of secular COPD rates in Africa. See Fig. S11 for separate estimates by disease.

We analyzed the mortality impacts and greenhouse gas (GHG) emissions produced by household energy use in Africa. Under a business-as-usual (BAU) scenario, household indoor air pollution will cause an estimated 9.8 million premature deaths by the year 2030. Gradual and rapid transitions to charcoal would delay 1.0 million and 2.8 million deaths, res...

Introduction- Anaemia is a disease of public health importance with multi-causal pathways. Previous literature suggests the role of indoor air pollution (IAP) on haemoglobin levels, but this has been studied less due to logistic constraints. A high proportion of the population in developing countries, including India, still depends on unclean fuel,...

... In fact, gas is more advantageous than charcoal in terms of energy efficiency, the health quality of the food (formation of carbonaceous substances) and the environment. However, their high cost and availability limit their use in developing countries, particularly in sub-Saharan Africa, unlike charcoal which is available and affordable (IEA, 2002;Ellegard et al., 2003;Bailis, 2005;Jonhson, 2009). In addition, it was showed that the type of fuel used affects the formation of HAPs during meat grilling (El Badry et al., 2010;Viegas et al., 2012). ...
... In addition, it has been suggested that the use of coal as a fuel to replace wood shops lead to reduction of household indoor pollution levels and the related deaths. (Bailis, Ezzati, and Kammen 2005;Bakry et al. 2014) Although, the previous damage caused during biochar production, but there are many benefits of utilizing biochar in the production of plants. Lehmann and Rondon (2005) investigated that biochar can be applied to agricultural soil and turn it into a valuable resource to improve crop yield in infertility and acid soils which are scarce in food resources such as the sandy soil. ...

Biochar is a product resulting from pyrolyzing biomass and is rich in carbon and several mineral. Nowadays, biochar is widely applied to agricultural soils as a soil conditioner. This research focuses on using biochar as a foliar fertilizer for wheat plants. The experiment was carried out at Shebin El-kom, El-Menoufia, Egypt, during two successive winter seasons 2015/2016 and 2016/2017 to evaluate the effect of different concentrations of biochar on the plant growth, yield and the nutritive value of wheat plant. Results showed that, the high concentrations of biochar (300 mg/L) improved the growth and yield characteristics of wheat. Biochemical constituents as expressed as total sugars, protein, phenols and indoles, as well as free amino acids, and nitrogen varied by growth stage and concentration of biochar. As a result, biochar application can be utilized to enhance the cultivated food crop and decrease the dependence on chemical fertilizers.
... Of particular importance in the SSA context is the rising use of charcoal-the fuel of choice for many people in the region-and its impacts on emissions, forest cover, soil fertility, and biodiversity. Bailis, Ezzati, and Kammen (2005) have shown that charcoal-intensive future scenarios using practices of the time could increase emissions by 140 to 190 percent. With SSA undergoing changes in population profiles, it is time to update these scenarios while paying attention to ecosystem loss, deforestation, and degradationwhich SDG15 aims to address, but which could contradict SDG7. ...

The global sustainable development agenda, the Sustainable Development Goals (SDGs), places energy systems-technologies to improve energy access, increase renewable energy generation, and tap energy efficiency-at its core to deliver what the United Nations General Assembly envisaged to be sustainable development for "people, prosperity and planet." But a fourth "p"-for politics-needs to be enmeshed in this framework. This chapter maps the extant literature on the connections between the politics of energy systems and sustainable development in sub-Saharan Africa, a region where most of the world's energy poor live. A focus on the politics of energy and sustainable development for people, prosperity, and planet remains a rich, yet understudied, frontier for future research. This chapter suggests an inclusive, interdisciplinary, and influential research agenda.
... Traditional biomass cookstoves cause significant environmental degradation (Arnold et al., 2006), contribute to global climate change (Bailis et al., 2005;Bond et al., 2004), and cause an estimated 4 million deaths a year (Lim et al., 2012). Fuel-efficient cookstoves, depending on quality and construction, have the potential to reduce household air pollution substantially and improve the health of cooks and children. ...
... In recent years, increasing attention has been devoted to the co-benefits associated with interventions in household cooking systems in developing countries, e.g., (Bailis et al., 2005;Smith and Haigler, 2008). The initial indications from several co-benefit analyses of cook systems suggest that some interventions are very attractive, both from the health and climate perspective. ...

Background and Aim In order to achieve improved global health, environmental health risks that could affect this goal have to be reduced as much as possible. This review thus aimed at determining the exposure levels, health risk assessments, and public health effects of polycyclic aromatic hydrocarbons (PAHs) in sub-Saharan Africa (SSA). This review was developed using guidelines provided for Preferred Reporting Items for Systematic Review and Meta-Analysis. Search was done on Google Scholar, Scopus, and PubMed databases. A study was included if it was carried out in SSA from 2000 to 2020 and written in English language. Fifty-two studies were finally retained and used for the review. Extracted data included the concentrations of 8 selected priority PAHs (including the PAHs prioritized for their carcinogenic potentials), their sources and reported outcomes. In SSA, PAHs exposure has been linked to the use of unprocessed biomass fuels for cooking, release of poorly treated petrochemical effluents into water bodies, and so on. Related public health effects included the occurrence of respiratory, cardiovascular abnormalities, and so on. Others included destruction of natural biodiversity in soil, water, and atmospheric environmental media. Health risk assessments also buttressed the occurrence of these public health effects of PAHs. In SSA, the region is exposed to a substantial amount of PAHs pollution which is associated with deleterious environmental and epidemiological effects. The adoption of healthier forms of energy, a change of attitude to one that favors environmental sustainability, and proper enforcement of environmental regulations are, however, necessary for attaining environmental sanity in SSA.

The authors analyzed the dynamics of greenhouse gas (GHG) emissions from household fuel use in sub-Saharan Africa from 2000 to 2050. The scenarios included a business-as-usual (BAU) scenario, in which fuel consumption and tree-harvesting practices change little except through population growth and urbanization, and large-scale shifts to charcoal- and petroleum-based fossil fuels. The authors also considered the role of charcoal production technologies and sustainability of biomass harvesting. GHG emissions from the various scenarios varied by a factor of 4, with the lowest emissions in the BAU fuel-use scenario with charcoal production and sustainable biomass harvesting and the highest in the charcoal fuel scenario without sustainable harvesting and charcoal production. In only two scenarios, those with sustainable biomass harvesting and charcoal production, the emissions had an inverted-U pattern. Therefore, an inverted-U pattern was highly dependent on technology and policy instruments.

The paper considers the use of a non-edible plant, Jatropha Curcas (JC), for the production of biofuel as a substitute for traditional fossil fuel. The whole production chain is analyzed; energy and environmental balances are reported. The investment value in biofuel from JC is also studied, and both its intrinsic and option values are calculated. A reference case is evaluated, namely, the cultivation of JC as substitution for conventional fuel in a specific less developed country, Kenya, that lies in the tropical region where JC grows. The investment is modelled as a perpetual investment call option. It is shown that the Net Present Value is positive for a vast range of discount factors and investment costs, while the option value depends crucially on the parameters of the model. Finally, the case of a relinquishment requirement for the specific land-use is also evaluated by modeling the corresponding American call option value; it is shown that a land-use release requirement does not change the optimal investment strategy.
