Global farming is at a crucial juncture in its evolution. Over 9000 years ago, humanity shifted from a hunter-gatherer lifestyle to stationary agriculture, sparking the "Agricultural Revolution" and putting soil at the forefront of agricultural focus. However, contemporary farming practices have seen an extreme shift in focus from the original revolution, that is, from tending plants to highly chemical-centric and extractive farming methods known as the "green revolution". In this process, soil has paid a heavy environmental price, with a substantial amount of land becoming unsuitable for agriculture over the past century. The 1992-93 World Resources Report by the United Nations issued alarming conclusions, revealing that nearly 10 million hectares of the world's best farmlands have been destroyed by human activity, including the green revolution. Additionally, over 1.2 billion hectares of land worldwide have suffered serious damage and can only be restored at a great cost. This loss of soil capability can result in significant food shortages in the next two to three decades.
One significant impact of this issue is that as usual, people in the disadvantaged nations will bear the brunt of the consequences. Approximately two-thirds of the seriously eroded land is located in Asia and Africa, with around 25% of the cropped land in Central America being moderately to severely damaged. The percentage of affected land in North America is relatively low, at only 4.4%. Soil degradation is the primary cause for the dramatic decline in food production in 80 developing countries during the past decade, with nearly 40% of global farming conducted on small parcels of land measuring 1 hectare or less. This situation is characterized by ignorance and poverty. In India alone, more than 120.40 million hectares of the total 328.73 million hectares of geographical area have suffered from degraded soils due to the green revolution. The State of Punjab, known as the "cradle of Indian green revolution" is a clear example of this environmental hazard, specifically in relation to soil resources. Thousands of hectares in this region cannot sustain plant growth without significant investment in soil reclamation, resulting in a substantial drain of national resources. All of this, proves beyond a shadow of doubt, the critical role that soil plays in human sustenance.
