Substantial loss of nitrogen (N) in reactive forms (nitrogen species except for N 2) induced by agro-food system is a cause of the environmental degradation and harms human health. The main factors influencing the food N footprint of the Indian Subcontinent (ISC) are the nitrogen use efficiency (NUE) of crop cultivation and religious dietary cultur...

The study conducted a time series analysis on the religion-sensitive food phosphorus (P) footprint of the Indian subcontinent which had increased from 0.91 in the 1960s to 1.18 kg-P capita-1 year-1 in the 2010s. Buddhists had the lowest food P footprint consistently. The food P footprint is expected to decrease by approximately 19% in the 2050s if...
Article
Full-text available
The excessive consumption of nitrogen (N) and phosphorus (P), two vital nutrients for living organisms, is associated with negative environmental and health impacts. While food production contributes to a large amount of N and P loss to the environment, very little N and P is consumed as food. Food habits are affected by multiple regulations, inclu...

The study estimated the food N footprint of Indian subcontinent considering religious food cultures since 1960s to 2010s, and forecast that up to 2050. It was found that average food N footprint of Indian subcontinent had been increased from 7.96 kg-N capita-1 year-1 to 9.41 kg-N capita-1 year-1 since 1961 to 2013. The Buddhist had the lowest food...

Nitrogen (N) is an essential nutrient for all living organisms. Excessive N loss in air and water can cause both environmental problems like acid rain and ozone layer depletion, and human health problems like respiratory issues. The N footprint explains anthropogenic N loss in the environment. Food N footprint is controlled by multiple stimuli incl...

Phosphorus (P) is an essential nutrient for all living organisms. With 80% of global P consumed as fertilizers, the agriculture sector acts as the largest user of P. However, only 20% of mined P is actually consumed as food. This study takes the first step toward estimating a detailed food P footprint of a South Asian country (India) by considering...
