“…This indicates that the number of applied adaptation measures was not at all, or only insignificantly, reduced due to ICS usage in Idifu. Hafner et al (2018) show that the fuelwood savings of ICS in Idifu is between 15.6% and 37.1% compared to TSF. Hence, we would expect that the overall number of coping strategies in Idifu to be lower than in Mzula due to the reduced demand for fuelwood in Idifu.…”

In Tanzania, the majority of the rural population still relies on fuelwood as their major source of cooking energy. The adaptation measures of small-scale farmers in response to increasing fuelwood scarcity play a key role in altering the course of nutrition insecurity, environmental degradation, and economic instability. This study delivers a classification of coping strategies that does not exist in the literature. Furthermore, it analyses the adaptation measures applied by small-scale farmers in the semi-arid region of Dodoma district in response to fuelwood scarcity. A comparison between two case study sites provides information on the choice of adaptation measures by households. Overall, 28 coping strategies from 24 studies are identified, then differentiated into preventive and acute measures that are arranged into eight clusters. The classification is then used as a codebook to identify applied coping strategies at two case study sites. In total, 23 adaptation measures, including two strategies not cited in the literature, were identified through 39 household interviews. This suggests that the majority of coping strategies applied are independently from regional and social conditions. The majority of the strategies applied at the case study sites and described in the literature are acute measures that do not tackle the underlying problem triggering forest degradation. It is observed that the adaptation measures across the case study sites are widely congruent, thus showing that acute strategies are not replaced by preventive strategies but rather co-exist.

“…At the same time, farms steadily move into new areas, accelerating the clearing of forest land (Goulden et al 2009), leading to dilapidated forest and woodland areas (Mutabazi 2016). Idifu has approximately 1200 households (Hafner 2016), while Mzula has around 750 households (Mutabazi 2016). Most of the households are subsistence farmers.…”

“…Despite the fact that collecting biomass fuel to provide cooking energy for rural families is an unpaid burden, women in the rural areas of developing countries devote valuable time and effort at the expense of education and income generation, to this work [29,35]. This study however indicates that when this labour is quantified and monetarised, the positive impact of utilising improved cook stoves [30] on feedstock collection is evident in economic terms, in addition to their contribution in reducing carbon footprint [23,24] and health impacts.…”

In near future, wood-based biomass energy will remain the main cooking energy for households in East Africa, especially for poor households due to its availability and affordability. Alternative biomass fuels however exist. Economic viability of these alternatives is important due to its potential to influence their adoption and sustained use. This research evaluates the economic efficiency of firewood, charcoal, biogas, jatropha oil, and crop residue briquettes value chains in the rural-urban contexts of Kitui, Kenya, and Moshi, Tanzania, using Life Cycle Costing (LCC) methodology. LCC helps to identify areas along the value chains where costs occur and where improvements are feasible. Jatropha oil manual value chain has the highest cost. Firewood use with improved cook stoves is cost efficient. In Moshi’s rural context, royalty fees increases cost of charcoal. Similarly, biogas in Kitui is less likely to be economically viable. Briquettes however have a competitive advantage over charcoal. The costs are dominated by fuel provision compared to cost of stoves. Therefore, payment schemes that improve adoption of improved stoves perceived as expensive will substantially reduce fuel cost. Enhancing availability and accessibility of technologies such as briquette presses will enhance biomass energy access and provide a source of income for households.

“…Most households comprise subsistence farmers, who use fuelwood as their main energy source for cooking and boiling water in both villages. Idifu consists of approximately 1,200 households (Hafner, 2016) and Mzula has around 750 households (Mutabazi, 2016). Two different cooking technologies are used at the case study sites.…”

About 3 billion people worldwide depend on fuelwood to meet their domestic energy needs. Almost 90% of the population in Sub-Saharan Africa use fuelwood-based forms of energy. However, its use is often unsustainable and is one driver of environmental degradation. In Tanzania, the majority of rural residents depend on fuelwood as their major source of cooking energy. The adaptation measures applied by small-scale farmers in response to fuelwood scarcity are typically unsustainable with regard to socioeconomic , environmental, and food security dimensions. This study applies a methodological framework that assesses the personally experienced impact of coping strategies by local stakeholders on sustainability criteria. This framework comprises (1) the selection of appropriate adaptation measures; (2) the identification of local sustainability criteria; and (3) the participatory impact and frequency assessments at two case study sites in the semi-arid region of Dodoma in central Tanzania. Overall, eight coping strategies from 23 measures applied in the region were selected and four sustainability criteria defined by local key informants were identified. The participatory impact and frequency assessment show that the strategies of "on-farm tree planting" and "use of improved cooking stoves" are rated as positive across all four sustainability criteria and are regularly applied by the farmers. Two of the eight strategies are clearly negative: "eat fewer meals" and "increase in walking distance to collect fuelwood." These measures are regularly and widely used by farmers, thus amplifying the negative rating. Overall, the experiences of farmers suggest that applied coping strategies have the greatest negative effect on the environmental condition and, on average, a rather positive effect on economic conditions. The results offer an approach for developing a reliable monitoring of how adaptation measures are applied in response to fuelwood scarcity and to achieve distinct values for benchmarking.
