Continue: What is the role of nano technology in addressing issues related to food security?

iii) Reduced pests due to efficient killing of pests.

iv) Low nano-pesticide usage → reduced soil health issues.

v) Low emissions from fields.

vi) Improved soil biodiversity.

Potential Risks of usage of these:

i) Long term impacts still not fully known

ii) Bioaccumulation and biomagnification of nano-pesticide—may cause cancer.

iii) Infiltration into groundwater or surface runoff.

iv) Impact on biodiversity—may harm soil microorganisms.

Nano-technology in agriculture is helping improve farm productivity. However, the full impacts of it needs to be understood. Methods such as crop notation, diversification, permaculture can help improve soil health and improve from productivity.
