Energy is a key factor in the economic development. Currently, however, millions of people across the world suffer from energy poverty, having little or no access to energy for cooking, lighting, heating, cooling, or using information and communication technologies. Objective of this study was to investigate the domestic energy sources for households and the impact of biomass use as a source of energy on the environment and food insecurity in the drought-affected northern highlands of Ethiopia. A total of 398 household heads were interviewed using a structured questionnaire, whereas 16 focus group discussions and 12 key informant interviews were conducted. Descriptive data analysis techniques were used to analyze quantitative data while content analysis methods were used to analyze qualitative data. The use of traditional biomass fuels such as firewood, charcoal, crop residue, animal dung, and biomass residue that can be combusted were prevalent in the area, which aggravated the degradation of agricultural lands. As commented by the majority of respondents, the move towards the adoption of modern energy sources was not common due to finance (98%), access (97%), durability (97%) and lack of awareness (93%). The findings showed that land degradation has been severe to the extent that no grain yield can be collected from crop production. As a result, people were exposed to both chronic and transitory food insecurity, and hence the majority of people make their living on food aid. In food-insecure areas, relying on biomass energy could increase land degradation or retard the speed of land restoration, which adversely affects agricultural production and food security. Investing in alternative energy technologies can improve the environment, food security, and people's health.
能源是经济发展的关键因素。然而,目前全球仍有数百万人遭受能源贫困,他们几乎无法获得用于烹饪、照明、取暖、制冷或使用信息和通信技术的能源。本研究的目的是调查埃塞俄比亚北部高地受干旱影响地区家庭的国内能源来源,以及生物质作为能源对环境和粮食不安全的影响。总共对 398 户家庭户主进行了访谈,使用了结构化问卷,同时进行了 16 次焦点小组讨论和 12 次关键知情人访谈。描述性数据分析技术用于分析定量数据,而内容分析方法用于分析定性数据。该地区普遍使用传统生物质燃料,如薪柴、木炭、农作物残渣、动物粪便和可燃烧的生物质残渣,这加剧了农业土地的退化。正如大多数受访者所评论的,由于资金(98%)、获取(97%)、耐用性(97%)和缺乏意识(93%),采用现代能源的举措并不常见。研究结果表明,土地退化已经非常严重,以至于农作物生产无法收获任何粮食产量。因此,人们面临着慢性和暂时性粮食不安全,因此大多数人依靠粮食援助维持生计。在粮食不安全地区,依赖生物质能源可能会加剧土地退化或减缓土地恢复的速度,这会对农业生产和粮食安全产生不利影响。投资替代能源技术可以改善环境、粮食安全和人民健康。
