Can regenerative farming reverse climate change and conservation agriculture contribute to mitigating climate change and reducing greenhouse gas emissions?
Conservation and regenerative agriculture Through the promotion of methods that improve soil health, biodiversity, and carbon sequestration, agriculture has promise in mitigating climate change. These techniques, which include crop rotation, cover crops, minimal soil disturbance, agroforestry, etc., assist in absorbing atmospheric carbon dioxide and storing it in the soil to lower greenhouse gas emissions. They also support long-term climate resilience and environmental sustainability in agricultural systems by enhancing soil structure, water retention, and resilience to extreme weather events. These factors all work together to promote sustainable agricultural productivity and ecosystem health.
Dear, Dr. RK Naresh
The answer to your question is almost yes.
But your question is incomprehensible considering the three components presented.
Because, all the agricultural process and involved with the climate depend on agricultural soils. In this case, the following link can help to ask more questions related to the state of the climate trend.

Climate changes are partly due to GHG.
GHG comes from many sources.
Methane is one of them. A farm could generate methane from rotting and composting piles.
To avoid this GHG, anaerobic digestion can be achieved.
Adding a BioDigester to a regenerative farm could contribute to reduce GHG and generate ENERGY, fertilizer, amendments.
In my area, Winter is defavorable to grow plants. Having BIOgas could enable gas-lighting (elongate photoperiod), produce heat and CO2 for the Greenhouse in the same time.
BURNING methane produce CO2.
The end is producing 1GHG of CO2 instead of 22@24 GHG from methane.
Direct contribution to climate change.
for all farming attitudes :
Carbon and Nitrogen sequestration : tillage is known to release lots of Nitrogen (easily returnable into atmosphere) and carbon (from dead mycroorganisms). Tillage should be avoided.
I think that this can be corroborated by some gasses analysis by satellites.
Less work, results into less pollution. (you could add the fuel for tractor), better soils health.
Undoubtedly, human activities, especially those altering the earth's surface, have a clear impact on climate. Adopting environmentally friendly agronomic practices can reduce greenhouse gas emissions and mitigate the intensification of climate change. Farmlands themselves can act as significant carbon sinks. Our task is to re-sequester the substantial carbon emissions caused by industrialization back into the soil, although the effectiveness of these technologies varies by region.
As others have stated, the answer is yes, but I will break down the reasoning in three categories: logical, theoretical, and practical.
Logically, the fact that humans have created, at least in part, climate change indicates that human activity if properly directed can have the opposite effect.
Theoretically, with a sufficient understanding of the systems in place we will be able to put efforts into leverage points where a relatively modest amount of efforts will have larger effects. Conversely, attempting to adjust climate without an understanding of the systems in play has a high likelihood of failure where we run out of finite resources trying to change a symptom rather than the cause.
Practically, the methods you specified are only part of the equation, just as CO2 is only one of the greenhouse gasses in play. To have a measurable effect, two conditions must be satisfied:
The trouble is when terms are either not fully understood, or intentionally "greenwashed". This is clearly not your intent, but understand that others may have a different definition of regenerative farming and conservation agriculture, so any such statement would do well with either an explicit or referenced definition. The definitions I am going to choose to work with are these:
- Regenerative Farming: https://regenerationinternational.org/2017/02/24/what-is-regenerative-agriculture/
- Conservation Agriculture: https://www.fao.org/conservation-agriculture/en/
Within the context of the question you asked "Can regenerative farming reverse climate change and conservation agriculture contribute to mitigating climate change and reducing greenhouse gas emissions"? and within the definitions above, I am sorry to say that the answer is no.
That said, using these techniques as part of a larger effort, the answer is a resounding yes, and in fact, it is the only way forward. One particular thing did not get us where we are today, nor did climate change occur overnight. We must act on multiple fronts, and with a sustained effort over time.

Regenerative farming and conservation agriculture hold significant promise in mitigating climate change and reducing greenhouse gas emissions. Regenerative farming focuses on restoring soil health, biodiversity and ecosystem resilience through practices such as minimal tillage, cover cropping, crop rotation and integrated livestock management. By enhancing soil carbon sequestration, regenerative farming not only improves soil fertility and water retention but also mitigates climate change by removing carbon dioxide from the atmosphere and storing it in the soil. Additionally, conservation agriculture emphasizes sustainable land management practices that minimize soil disturbance, maintain soil cover, and promote crop diversity. These practices help to preserve soil structure, reduce erosion and enhance carbon sequestration, thereby contributing to climate change mitigation and resilience to extreme weather events. Overall, the adoption of regenerative farming and conservation agriculture can play a vital role in reversing climate change by sequestering carbon, reducing greenhouse gas emissions and fostering sustainable food production systems.
