Hello sir,

Agricultural system contributes a lot to the global green house gas emissions and really there is a need to quantify it, so that potential measures can be adopted to control it.

While searching on the internet, I came across one technique called as Chamber based flux measurement technique. You can access the details from the link given below.

Hope it solves your query.

Thanks and Regards

Emissions of greenhouse gases (GHGs) is the most important driver of human-induced climate change. Agricultural activities contribute 10%–14% of global anthropogenic GHG emissions . The main gases emitted by agricultural activities are:

Carbon dioxide

Methane

Nitrous oxide

Agriculture is a victim of climate change. Rising temperatures, erratic rainfall and extreme weather events can lower productivity, destroy harvests and threaten food security and livelihoods.But this is only half the story. Agriculture also contributes to climate change. Even by modest estimates, it is responsible for nearly 14 percent of greenhouse emissions - primarily through nitrous oxide, methane and carbon dioxide. When land conversion and deforestation are taken into account, the figure is closer to 30 percent.

If land management practices are changed in ways that increase the soil organic carbon, CO2 is effectively removed from the atmosphere and stored or 'sequestered' in the soil. The size of the 'sink' is increased. Farm practices that contribute to the carbon sink are:

1. Reduction in tillage.

2. Restoring degraded land, improving pasture management.

3. Reducing fallow periods.

4. Adding animal manures to the soil.

5. Crop residue management.

6. Using legumes and/or grasses in crop rotations.

7. Converting marginal crop land to perennial grass or trees.

8. Using rotational grazing and high-intensity/short duration grazing.

9. Planting shrubs and trees as shelterbelts.

10. Restoring wetlands.

Thank you Richa Khanna and Prem Baboo for your detailed inputs and suggestions. I will also go through the link shared by you.

Thank you sir for your kind consideration.

During last couple of days. I was doing some desk research to find the tools for measuring GHG emissions in Agriculture. Recently rI came through the EX-ACT Carbon tool developed by #FAO and #World Bank. I found this tool quite comprehensive and practical. Sharing the link.

Still, if anyone has any tools and mechanism in minds. May refer the same.

Thanks
