English
This study analyzes farmer adoption of soil conservation practices under carbon payment programs, using a dynamic optimization model. Required payments vary from $8/ton C/year on well-drained soils to $32/ton C/year on poorly drained soils, highlighting the need for spatially targeted incentives. Risk in sequestration outcomes increases payment requirements and affects practice choice.

日本のGX文脈において
日本の農業分野でも、J-クレジット制度やみどりの食料システム戦略の下で土壌炭素隔離が注目されている。本論文はリスクを考慮した支払い設計の理論的基礎を提供し、日本の土壌特性や農家行動に合わせた制度設計に示唆を与える。
In the global GX context
Globally, carbon payment programs for agricultural soils are emerging (e.g., in the US and EU). This paper provides a rigorous economic framework for designing spatially differentiated payments that account for soil heterogeneity and farmer risk preferences, relevant for voluntary carbon markets and government programs.

📄 Abstract（原文）
Agricultural soils represent one of the largest underutilized opportunities for climate mitigation through land-based carbon sequestration. This study analyzes how farmers make long-term decisions about adopting soil conservation practices, such as no-till and reduced tillage, when soil organic carbon (SOC) accumulation generates additional payments, while explicitly considering risk associated with SOC sequestration variability. Using an infinite-horizon dynamic optimization model, the study quantifies the carbon payment levels required to incentivize adoption across different soil types. Results show that the required payments vary widely, from $8/ton C/year on well-drained soils to $32/ton C/year on poorly drained soils, highlighting the need for spatially targeted carbon incentives. The analysis demonstrates that risk in the SOC sequestration amount affects farmer choices: higher uncertainty increases the payments needed and can lead farmers to prefer lower-risk, lower-reward practices. For farmers who value intertemporal consumption smoothing, compensation requirements rise with the elasticity of intertemporal substitution. These findings underscore the importance of accounting for soil heterogeneity, outcome variability, and intertemporal preferences when designing effective carbon payment programs to promote long-term soil carbon sequestration.Institutional subscribers to the NBER working paper series, and residents of developing countries may download this paper without additional charge at www.nber.org.
