In a climate-smart millet system, GHG emissions from conventional farming are 2.4 t CO₂e/ha while CSA practices reduce them to 1.6 t CO₂e/ha. Calculate the mitigation potential (in %) and estimate carbon savings over 1000 ha for 5 years. Discuss how IoT-based monitoring can ensure data accuracy and verification.
Dear friend Himanshu Tiwari
Thank you for raising such a thought-provoking question regarding the quantification of greenhouse gas (GHG) mitigation in climate-smart agriculture (CSA), and the potential of IoT technologies to enhance monitoring accuracy. This is indeed a timely topic as sustainable farming practices become increasingly vital.
To calculate the percentage reduction in emissions per hectare, we use the formula:
Mitigation (%) = [(Conventional emissions – CSA emissions) / Conventional emissions] × 100
Applying your figures (2.4 t CO₂e/ha for conventional and 1.6 t CO₂e/ha for CSA), the reduction is [(2.4 – 1.6) / 2.4] × 100 = 33.3%. Over a 1000-hectare area for 5 years, the total carbon savings would be (2.4 – 1.6) × 1000 × 5 = 4,000 t CO₂e. This clearly demonstrates the significant mitigation potential of CSA practices at scale.
Regarding IoT, these technologies can greatly enhance the accuracy and reliability of GHG data by providing continuous, real-time monitoring of key environmental parameters such as soil moisture, temperature, and CO₂ levels. Such data not only verifies actual savings against projections but also ensures transparency and supports adaptive management. By enabling ongoing adjustments to farming practices, IoT systems help optimize both environmental and operational outcomes.
If you have further questions or would like to discuss specific IoT solutions for your context, please let me know. I look forward to your thoughts.

GHG mitigation = ((2.4 - 1.6) / 2.4) × 100 = 33.33%. Carbon savings = (0.8 t/ha × 1000 ha × 5 years) = 4000 t CO₂e. IoT sensors help monitor field emissions, soil health, and inputs in real time, enhancing measurement accuracy and informing adaptive practices for better mitigation.
Mitigation potential = ((2.4 − 1.6) / 2.4) × 100 = 33.33%
Reduction per hectare per year = 2.4 − 1.6 = 0.8 t CO₂e/ha/year
Over 1000 ha for 5 years: 0.8 × 1000 × 5 = 4,000 t CO₂e
