ナイジェリアの石油補助金撤廃と通貨安によるエネルギー危機が、都市部カツィナの家計の調理燃料選択に与えた影響を評価。384世帯の調査とロジスティック回帰分析により、LPG利用が58.9%から39.8%に減少し、木炭・薪への回帰が確認された。燃料スタッキング戦略が一般的で、エネルギー貧困と室内空気質への悪影響が示唆される。
English
This study evaluates the impact of Nigeria's energy crisis on urban household cooking fuel choices in Katsina. A survey of 384 households and logistic regression reveal a significant shift from LPG to biomass fuels, with LPG use dropping from 58.9% to 39.8%. Fuel-stacking is common, indicating energy poverty and indoor air quality concerns.

日本のGX文脈において
日本のGX文脈では、エネルギー危機下での燃料転換の実証データは、途上国支援や国際協力の政策立案に参考となる。また、エネルギー貧困の指標や家庭部門の脱炭素化の課題を理解する上で示唆に富む。
In the global GX context
This paper provides empirical evidence on energy poverty and fuel switching in Sub-Saharan Africa, relevant to global discussions on just transition and universal energy access. It highlights the risk of energy regression due to price shocks, informing policies for clean cooking and social protection.

📄 Abstract（原文）
The global energy crisis driven by crude oil price volatility, currency devaluation, and the removal of Nigeria's petroleum subsidy, has placed unprecedented strain on urban household energy budgets. This study evaluates household energy transition in Katsina metropolis, the capital of Katsina State, Nigeria, using the energy ladder and fuel-stacking models as its conceptual anchor. A cross-sectional survey of 384 households, sampled proportionately across nine metropolitan wards using Cochran's formula, was analysed alongside binary logistic regression to identify determinants of downward energy switching. Results show a marked reversal in household cooking-fuel choice: the share of households citing LPG as their primary cooking fuel fell from 58.9% before the crisis to 39.8% currently, while reliance on charcoal and firewood rose by 11.0 and 8.4 percentage points respectively. Regression results indicate that perceiving the LPG price increase as "severe" (OR = 3.14, p < 0.001) and lower household income (OR = 0.52, p < 0.001) were the strongest predictors of downward switching, while tertiary education and grid electricity access were protective. Rather than fully abandoning modern fuels, most affected households adopted a fuel-stacking strategy, retaining LPG for quick tasks while reverting to biomass fuels for daily cooking, consistent with the fuel-stacking rather than the strict linear energy-ladder model. The findings suggest that urban Nigerian households are experiencing crisis-induced energy regression despite urban status, with implications for indoor air quality, gender burden, and energy poverty. The study recommends targeted LPG cylinder subsidies, cash-transfer-linked clean cooking support, and expanded solar mini-grid access for urban low-income wards. Keywords: Household Energy Transition, Energy Ladder, Fuel Stacking, Energy Poverty, Global Energy Crisis.
