本研究は、ネパール・チュリヤ地域の3つのアグロフォレストリーシステム（農林複合、放牧林、家庭菜園）の炭素蓄積と経済性を統合評価。総炭素蓄積に有意差はないが、農林複合が年間蓄積速度で優れる。放牧林が最も高い費用対効果を示し、家庭菜園は低収入・炭素優先型のニッチを占める。統合指標RBPIでは放牧林が最適と判定。
English
This study integrates carbon stock measurements (five pools) and economic indicators (NPV, BCR, opportunity cost) for three agroforestry systems in Nepal's Churiya Hills. While total carbon storage does not differ significantly, agri-silviculture accumulates carbon faster annually. Silvopasture is the most financially attractive and ranks highest on a composite Ratio-Based Performance Index, with homegardens providing a low-income, carbon-priority option. Institutional support is needed for scaling.

日本のGX文脈において
日本ではアグロフォレストリーは一般的ではないが、温暖化対策としての土地利用評価手法や、小規模農家の便益と炭素貯留のトレードオフ分析は、国内外のJ-クレジットや生物多様性施策に示唆を与える。
In the global GX context
This paper provides a replicable multi-criteria framework for evaluating land-use systems that balance carbon storage and economic returns. It is relevant for global climate-smart agriculture programs and REDD+ projects, demonstrating how integrated assessment can inform smallholder adoption and policy design.
👥 読者別の含意
🔬研究者:Offers a methodological template integrating carbon and economic indicators via weighted performance index, applicable to other land-use systems.
🏢実務担当者:Shows which agroforestry system (silvopasture) provides best financial return and carbon performance, aiding land-use planning.

📄 Abstract（原文）
Abstract Agroforestry is widely promoted as a climate-smart land use system, yet most studies evaluate its carbon, economic, or opportunity-cost dimensions in isolation, leaving the integrated trade-offs faced by smallholders unclear. In this study, we compared the integrated performance of three agroforestry systems: agri-silviculture, silvopasture, and homegarden in Nepal’s Churiya region. Carbon stocks across five pools (above and below-ground biomass, saplings, litter, and soil organic carbon) were measured. Also, household economic data collected yielded net present value (NPV), benefit–cost ratio (BCR), and opportunity cost per tCO 2 e. The three normalized indicators (total carbon stock density, BCR & cost-efficiency) were combined into a weighted Ratio-Based Performance Index (RBPI), with a sensitivity analysis under four different weighting scenarios. Total carbon stocks did not differ significantly across all three systems however agri-silviculture accumulated total carbon faster annually than silvopasture and homegarden. All three systems were financially viable, with cumulative three-year NPVs ranging from USD 939 to 4097 ha −1 . The benefit–cost ratio identified silvopasture as the most financially attractive agroforestry system, while homegardens delivered the lowest opportunity cost of carbon. The RBPI ranked silvopasture as the highest, homegarden as the intermediate, and agri-silviculture as the lowest, and this ranking held across all four weighting scenarios. Hence, silvopasture emerged as the most balanced multifunctional system in the Churiya context, with homegardens occupied a complementary low-income, carbon-priority niche. Realizing these gains, however, will require institutional support, durable tenure, and farmer-led extension embedded within Nepal’s existing community-forestry architecture.
