“…For all four groups, we find that MHHs, FHHs, de facto FHHs and de jure FHHs who use fuel wood are 13.2%, 12.8%, 12.5% and 13.9% respectively, less likely to be food secure. This outcome contradicts the notion that abundance of/or the reliance on wood fuel would be helpful in dealing with the food security issues in developing countries ( Waswa et al., 2020 ; Mulhollem, 2018 ). The results found is an indication that the food security status of the about 50% of Ghanaians who rely on fuel wood for cooking is at risk.…”

“…(2016) among other things indicated that fuel wood dependent households that lack access to fuel wood were more food insecure. In Kenya, Waswa et al. (2020) found that the scarcity of wood fuel resulted in changes in cooking habits whereby households opted to cook composite meals as opposed to single meals.…”

“…Another emerging issue in the literature is the role of wood fuel 1 - the direct use of wood (firewood), charcoal and recovered wastes in wood ( Kwarteng 2015 ; Arnold et al., 2003 ) - in attaining food security. It is argued that the abundance of/or the reliance on wood fuel would be helpful in dealing with the food security issues ( Waswa et al., 2020 ; Mulhollem, 2018 ). Wood fuel is the commonest cooking source for many households in developing countries, particularly those in the sub-Saharan region of the African continent.…”

“…This has serious implications for health, with 490,000 premature deaths per year in SSA, which are mainly children and women [3]; for the environment, with the striking loss of forests and biodiversity due to the unsustainable biomass source [7]; and for productivity, due to the time expenditure for wood collection that increases with deforestation. Indeed, forest depletion has consequences over nutrition, fostering faster recipes with a lower use of wood or charcoal that are also frequently less healthy [8]. In the last decades, the efforts of governments and international agencies have been focused on the promotion of improved cook stoves [9], with a higher thermal efficiency compared to traditional open fire or "three stone" cookers and allowing the same biomass fuels.…”

Solar E-Cooking with Low-Power Solar Home Systems for Sub-Saharan Africa

et al. 2021

The e-cooking feasibility was evaluated for two of the main staple foods across rural Sub-Saharan Africa (rice and maize porridge) considering basic solar home systems (SHS) of 100–150 W and using inexpensive market available low-power DC cooking devices (rice cooker and slow cooker). The coverage of e-cooking necessities was spatially evaluated for the African continent considering households of two, five, and eight people. While households of two people were able to be covered >95% of the days, the increase in e-cooking necessities implied that only larger PV generators (150 W) located in high irradiation sites (>2400 kWh/m2/year) were able to fulfill e-cooking, even in scenarios of households of five and eight people. Furthermore, the economic cost and the greenhouse gases emission factor (GHG) of e-cooking via small SHS were evaluated and benchmarked against traditional technologies with wood and charcoal considering three-stone and improved stoves and liquefied petroleum gas (LPG) cookers. The GHG for e-cooking was 0.027–0.052 kgCO2eq./kg·meal, which was strikingly lower than the other technologies (0.502–2.42 kgCO2eq./kg·meal). The e-cooking cost was in the range of EUR 0.022–0.078 person/day, which was clearly lower than LPG and within the range of the cost of cooking with wood and charcoal (EUR 0.02–0.48 person/day). The results provided a novel insight regarding market available technologies with a potential of changing cooking conditions in this region.

“…The situation is aggravated by the fact that most smallholder farmers in rural Tanzania use unimproved cooking devices to cook their daily food [3], which reportedly consume more fuel than Improved Cook Stoves (ICS). Studies have shown that fuel scarcity leads to shifting cooking habits, including skipping meals, cooking composite meals, reducing the number of cooked meals per day, and cooking fast meals, which are often nutrientpoor [2,4]. Around 80% of the Tanzanian population depends on fuelwood to meet domestic needs, including cooking, boiling water, lighting, and heating [5].…”

Allometric equations for estimating on-farm fuel production of Gliricidia sepium (Gliricidia) shrubs and Cajanus cajan (pigeon pea) plants in semi-arid Tanzania

et al. 2021

Background Fuelwood is considered to be the primary source of cooking energy in Tanzania and, due to ongoing deforestation, access to fuelwood is becoming more cumbersome. On-farm agroforestry systems can reduce dependency on off-farm fuel; however, the output of on-farm produced fuel is typically uncertain as production potentials are often not known. In this paper, we have developed allometric equations to model the above-ground woody biomass (AGWB) production from intercropped Gliricidia sepium (Jacq.) Kunth ex Walp (Gliricidia) shrubs and Cajanus cajan (L.) Millsp. (pigeon pea) plants. Methods We used a destructive sampling approach, for measuring the dendrometric characteristics, such as the root collar diameter at a 20 cm stem height (RCD20) and the stem height to estimate the AGWB production. The models are based on 112 Gliricidia and 80 pigeon pea observations from annually pruned plants. Seven allometric equations were fitted to derive the best-fit models for the AGWB production. Results We found that using a natural log-transformed linear model with RCD20 as a single predictor variable provides the highest explanatory value to estimate the AGWB production (Gliricidia: R2 = 95.7%, pigeon pea: R2 = 91.4%) while meeting Ordinary Least Square (OLS) estimator requirements. Adding stem height as an additional variable to predict the AGWB production does not improve model accuracy enough to justify the extra work for including it. Conclusions While on-farm pigeon pea plants produced a stable amount of woody biomass per annum, annual fuelwood production from Gliricidia shrubs increased over the years. Compared to the annual fuelwood consumption data from the literature, our results show that on-farm produced fuelwood can substantially offset the demand for off-farm fuel, potentially resulting in household fuelwood autarky.
