ナイジェリア農業セクターのボランタリー炭素市場について、制度・市場構造が透明で小規模農家を包摂する炭素プロジェクトを支えられるか評価した研究。文献レビューと関係者インタビュー、PAC評価ツールで5本柱の準備指数を構築。政策・規制72%に対し金融が33%と遅れ、総合55%で「政策意図は強いが運用能力が弱い移行段階」と結論。MRV統一、炭素権利の明確化、アグリゲーションモデル、包摂的金融の優先介入を提言する。

English

This study assesses whether Nigeria's institutions and market structure can support transparent, smallholder-inclusive carbon projects in the voluntary market. Using a realist systematic review, key informant interviews, and a PAC readiness tool across five pillars, it finds uneven progress: policy/regulation 72%, institutional coordination 60%, market infrastructure 58%, inclusiveness 52%, and finance lagging at 33%, for an overall 55%. Nigeria sits in a transitional phase of strong policy intent but weak operational capacity, with gaps in AFOLU MRV, carbon ownership rights, and blended finance. Priority interventions include MRV harmonization, clarifying carbon rights and benefit-sharing, aggregation models, and inclusive financing.

日本のGX文脈において

日本企業のScope 3排出削減や海外クレジット調達の文脈で、途上国農業由来クレジットの品質・包摂性・MRV整備度を測る枠組みとして参考になる。JCMや二国間クレジットの案件形成時の制度リスク評価にも示唆。

In the global GX context

Adds a readiness-assessment framework for host-country carbon market integrity relevant to Article 6, ICVCM Core Carbon Principles, and corporate Scope 3 offset sourcing. Highlights MRV and carbon-rights gaps that determine credit quality in voluntary markets.

📄 Abstract（原文）

Abstract This study, which assesses readiness for inclusive and high-integrity carbon markets in Nigeria’s agricultural sector, evaluates whether Nigeria's existing institutional systems and market structure can support transparent, credible, and smallholder-inclusive carbon projects in voluntary carbon market opportunities in Nigeria. Using a realist systematic review of recent literature (2021–2025) and key informant interviews across public and private stakeholders, this study also adopted the PAC assessment tool to construct a readiness index across five pillars: policy and regulation, institutional coordination, finance, market infrastructure, and inclusiveness. The findings reveal uneven progress across these pillars, with policy and regulation scoring 72%, institutional coordination scoring 60%, market infrastructure scoring 58%, inclusiveness scoring 52%, and finance lagging 33%. This produces an overall readiness score of 55%, indicating that Nigeria is in a transitional phase characterized by strong policy intent but weak operational capacity. Despite the presence of guiding frameworks such as the Climate Change Act and the Long-Term Low-Emission Development Strategy, critical gaps persist. These include fragmented institutional mandates, the absence of a unified AFOLU MRV system, unclear carbon ownership rights (particularly on customary lands), and limited access to blended finance mechanisms necessary to support smallholder participation. The study identifies priority interventions: strengthening MRV harmonization, clarifying carbon rights and benefit-sharing frameworks, developing aggregation models, and expanding inclusive financing structures. Addressing these constraints will be essential for lowering transaction costs, improving transparency, and ensuring equitable participation. The paper concludes that translating policy ambition into functional carbon markets requires coordinated institutional reform, targeted investment, and inclusive governance to develop outcomes.
