    The influence of energy policy on charcoal consumption in urban households in Tanzania

    The sustainability of energy use in the residential sector has relevance for global initiatives to achieve sustainable development and limit climate change. Using the city of Dar es Salaam, in Tanzania, as a case study, we look at how national energy policy has influenced household cooking energy use between 1990 and 2018, and how en- ergy policy could achieve further progress to realise national and global priorities. The study involved question- naire surveys of households, retailers, transporters and producers of charcoal; semi-structured interviews with government officials and non-charcoal fuel suppliers; price data collection; a comparative analysis of prices and taxes for different cooking fuels; and policy and document review. Trends in energy policy and demand for different fuels, are compared. We find that Tanzania's national energy policies have focused on achieving an energy transition from biomass to electricity and fossil fuels, with an increasing focus on supply-side issues. Fiscal policy tools have been used effectively to reduce demand for kerosene, while increasing demand for lique- fied petroleum gas. However, this has not resulted in a transition away from biomass, with most households using multiple fuels (fuel stacking). Charcoal remains the cheapest (excluding firewood) and most widely used fuel, reflecting the strong influence of price in consumer fuel choices. Energy policy needs to acknowledge the continued dominance of charcoal in urban energy use. In the context of rapid urbanisation and increased energy demand, there is a need for sustainable urban energy planning across a range of fuel types including charcoal, in ways that balance economic, social and environmental outcomes. Greater inter-sectoral coordination is needed to improve the sustainability of urban residential energy supplies. © 2020 The Author(s).

    Tobacco growers at the crossroads: towards a comparison of diversification and ecosystem impacts
    (2009) Geist, Helmut J; tsung Chang, Kang-; Etges, Virginia; Abdallah, Jumanne M
    An international Framework Convention on Tobacco Control has been in force since 2005, also aimed at regulating tobacco farming: FCTC article 17 on diversification, and FCTC article 18 on socio-ecological issues. Relating to the FCTC, information was gained and evaluated from tobacco farmers of growing areas sampled from major world regions (Rio Grande do Sul/Brazil, Tabora/Tanzania, Meinung/Taiwan, and Germany/Europe). A local farming survey was carried out in 2007, using a common data protocol, which covered, among others, questions on area and production development, energy used in curing, workforce, economic livelihood situation, and diversification opportunities. In addition to the survey, secondary (national-scale) statistics, public testimonies and other published data were explored. We analyzed these data using a portfolio approach, which combined statistical analysis, meta-analytical study and descriptive narratives. The projected trend of a global shift of tobacco cultivation into the developing world is confirmed, but also refined. Wood is used in Brazil and Tanzania for curing Virginia green leaf, thus contradicting the projected continuous reduction of this energy source. Child labour remains a major component of family farm tobacco operations in Brazil and Tanzania, while the cost and availability of seasonal labour turns into a bottleneck of production in Germany. More diversification opportunities exist than generally claimed, but no efforts are seen to address poor and vulnerable growers, in particular. German and Taiwanese tobacco growers can reasonably be predicted to discontinue farming in the near future, while tobacco cultivation in Brazil and Tanzania is seen to expand, mainly due to the political economy of low-cost production. Conclusions are drawn with respect to the work of the UN Study Group on Economically Sustainable Alternatives to Tobacco Growing (ESATG), effective since 2007.
