日本語
保全型農業（CA）は不耕起・永続的被覆・輪作を原則とし、土壌健全性と資源効率を高める持続的農法である。本論文は土壌炭素・水分保持・養分動態・エネルギー使用・GHG削減への影響を整理し、生産性と資源利用効率の向上を示す。一方、初期投資・機械化不足・残渣管理・社会経済的制約が普及を妨げると指摘し、気候スマート農業への道筋を論じる。
English
Conservation agriculture (CA) — minimum tillage, permanent soil cover, and diversified rotations — is reviewed for its effects on crop productivity and resource-use efficiency. Evidence shows gains in water-use efficiency, soil organic carbon, nutrient availability, and reduced GHG emissions versus conventional tillage. Adoption barriers include upfront costs, mechanization gaps, residue management, and socio-economic constraints, especially in developing countries.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本では農林業はGX推進の対象だが、本論文は国内のSSBJ・有報開示やScope3算定に直接接続しない。ただし農業由来排出削減や食料システムの脱炭素に関心を持つ事業者・自治体には参考となる。
In the global GX context
Globally, agriculture accounts for roughly a fifth of GHG emissions, and CA is relevant to land-sector transition pathways and climate-smart agriculture finance. It connects indirectly to CSRD/ISSB land-use and Scope 3 agriculture categories, though it offers no disclosure framework itself.

📄 Abstract（原文）
Conservation agriculture (CA) has emerged as an environmentally sustainable and economically viable farming system capable of addressing the growing challenges of food security, climate change, soil degradation, and declining agricultural productivity. Based on the principles of minimum soil disturbance, permanent soil cover, and diversified crop rotations, conservation agriculture seeks to improve soil health while enhancing the efficient utilization of natural resources. The adoption of CA practices has gained momentum worldwide due to their potential to increase crop productivity, reduce production costs, conserve soil moisture, and improve resilience against climatic variability. Numerous studies have demonstrated that conservation agriculture contributes to higher water-use efficiency, enhanced nutrient availability, improved soil organic carbon, and reduced greenhouse gas emissions compared to conventional tillage systems. Moreover, these practices support sustainable intensification by maintaining long-term soil fertility and minimizing environmental degradation. However, the effectiveness of conservation agriculture varies across agro-climatic regions, crop types, soil characteristics, and management practices. Factors such as limited awareness, initial investment costs, inadequate mechanization, residue management challenges, and socio-economic constraints often hinder its widespread adoption, particularly in developing countries. This paper examines the influence of conservation agriculture practices on crop productivity and resource use efficiency by analyzing their impact on soil health, water conservation, nutrient dynamics, energy use, and environmental sustainability. It also discusses the major challenges associated with adoption and highlights future opportunities for promoting climate-smart and sustainable agricultural systems. The study concludes that conservation agriculture offers a practical pathway toward achieving productive, resource-efficient, and environmentally resilient agriculture for future generations.
