バングラデシュの稲作農家435戸を対象に、稲わらのすき込み導入への行動意欲と支払意思額（WTP）を分析。導入率は14%と低いが、31%が関心を示し、28%が平均37米ドル/ha/作期を支払う意向を持つ。気候脆弱地域（特に塩害地域）でWTPが高く、気候リスクが行動変容の触媒となることを示す。教育・世帯所得・農業機械へのアクセスが主要因で、機械レンタル補助が導入を促進しうる。
English
Surveying 435 rice farmers in Bangladesh, this study examines behavioral readiness and willingness to pay (WTP) for rice-straw incorporation. Adoption is low (14%) but 31% show interest and 28% would pay an average USD37/ha/season, revealing latent demand. Climate-vulnerable areas—especially salinity-affected—show higher WTP, suggesting climate risk catalyzes sustainable behavior change. Education, income, and farm-machinery access are key drivers; subsidized machinery rental could enable adoption below stated WTP.

日本のGX文脈において
日本では稲わら焼却は既に規制され、むしろ炭素貯留・バイオ炭・堆肥化による土壌炭素クレジット（J-クレジット）や農業由来GHG削減が関心領域。本論文は気候リスクが行動変容を促すという示唆を、日本の農業脱炭素・カーボンファーミング政策やScope 3農産物調達の議論に転用できる。
In the global GX context
While straw burning is largely regulated out in advanced economies, this study offers globally relevant evidence that climate risk itself can accelerate adoption of low-emission residue management in smallholder systems. It speaks to emerging agricultural carbon finance, Scope 3 agricultural supply-chain accounting, and just-transition finance for climate-vulnerable farm economies—areas increasingly addressed under CSRD and ISSB agricultural disclosures.

📄 Abstract（原文）
Abstract Open burning of rice straw remains widespread across many rice-producing regions, generating avoidable greenhouse gas emissions, air pollution, and soil degradation. Yet the transition to sustainable straw management remains limited, especially in climate-stressed smallholder systems. This study explores farmers’ behavioral readiness and economic preferences to adopt rice-straw incorporation, willingness to pay (WTP) for its adoption, and identifies how socioeconomic, farm and climatic factors shaping these decisions. Using a combination of contingent valuation method, ordered logit, Heckman selection, and double-hurdle models, we analyze survey data of 435 rice-farmers collected through stratified-random sampling from three climate-hazardous (i.e., drought, salinity, and flood) districts and one less climate-risk district of Bangladesh. Adoption of straw-incorporation is very low (14%), however, a larger share of farmers (31%) show interest in adopting and 28% are willing to pay an average of USD37/ha/season—revealing substantial latent demand for straw-incorporation. Farmers in climate-vulnerable areas show a significantly higher probability of paying for straw-incorporation than those in less vulnerable areas, with WTP highest in salinity-affected regions. The finding implies that climate risk acts as a catalyst for behavioral change toward adoption of sustainable straw-management. Education, household income and accessibility to farm-machineries are the key drivers of shifting towards straw-incorporation and its WTP. Given Bangladesh’s dependence on rental farm machinery, subsidized and accessible straw-management machinery rental services could enable adoption at costs below farmers stated WTP. These findings provide globally relevant evidence that climate risk can increase receptiveness to low-emission residue management in smallholder rice systems. For climate-vulnerable and resource-constrained agricultural economies, the results suggest targeted machinery access, increasing farmer’s awareness, and market-based incentives such as carbon finance to accelerate the shift from open burning to sustainable straw management.
