本研究はIPCC Tier 1aプロトコルを用いてナイジェリアの反芻動物（牛、羊、ヤギ）からの温室効果ガス排出量を推定した。1998年から2022年にかけて、家畜頭数と排出量が大幅に増加しており、牛が最大の排出源であった。特に腸内発酵由来のメタンが主要な排出源であり、改善された飼養戦略や遺伝子改良、堆肥管理などの対策が緊急に必要である。

This study estimates greenhouse gas emissions from ruminants in Nigeria using the IPCC Tier 1a protocol. Over 1998-2022, livestock populations and emissions increased significantly, with cattle as the largest source. Enteric methane dominates emissions, urging interventions like improved feeding, genetics, and manure management. Provides insights for national climate strategies.

日本のGX文脈において
ナイジェリアの畜産由来GHGインベントリの研究であるが、日本においても農業分野の排出算定手法（Tier 1a）の適用例として参考になる。ただし、日本の畜産は集約的で規模や管理が異なるため、直接的な示唆は限定的。
In the global GX context
This paper provides a case study of GHG inventory for livestock in a developing country using IPCC Tier 1 methodology, relevant for global carbon accounting and national climate reporting. While not directly applicable to corporate disclosure, it highlights the importance of agricultural emissions in national inventories.

📄 Abstract（原文）
The objective of the study was to estimate greenhouse gas emissions from ruminants using the Intergovernmental Panel on Climate Change (IPCC) Tier 1a Protocol. Primary data were collected from 360 respondents across livestock producing regions of Nigeria via structured questionnaires, complemented by secondary data from Food and Agricultural Organisation, National Agricultural Extension and Research Liaison Services and National Bureau of Statistics. Primary and secondary data on enteric and manure methane (CH4) and nitrous oxide (N2O) emissions were computed, analysed and validated for reliability following IPCC guidelines. Results showed that between 1998 and 2022, cattle, sheep and goat populations increased by 34, 134 and 135%, respectively. Similarly, total enteric methane and manure emissions increased by 64 and 62%, respectively, corresponding to CO2– equivalent of 65%. It was also evident that N2O from manure also increased by 69%, a CO2-equivalent of 66%. Cattle contributed the largest proportion of emissions, followed by goats and sheep, respectively. Low and high productivity systems accounted for >70 and 30% of total emissions, respectively. A significant increase in ruminant greenhouse gas emissions over the 25-year period with enteric CH4 as the largest emission source was evident. There is the urgent need for targeted interventions like improved feeding strategies, improvements in genetics and manure management through composting, anaerobic digestion and vermicomposting, to mitigate greenhouse gas emissions and optimise nutrient utilisation. Our findings provide critical insights for national climate strategies and sustainable livestock development in Nigeria.
