The Future: A Brief Comment
Avery pointed out in 1997 that without the crop yield increases that occurred since 1960, the world would have required an additional 10–12 million square miles (roughly the land area of the United States, the European Union countries, and Brazil combined) for agriculture, bound by 1950s technology, to achieve 1997 levels of food production. Avery claimed that modern high-yield agriculture is not one of the world’s problems, but rather the solution to providing sufficient food for all, sufficient land for wildlife, and protecting the environment. His claim is still valid and the need for further changes, many from chemical research, is unconditionally supported by the fact that all of the world’s land that is capable of supporting agriculture is now used and, barring a worldwide disaster, the human population will continue to increase for several decades. There is no land for agriculture to expand. That is not news to international organizations, most countries, nongovernmental organizations, companies engaged in agriculture, faculty of Colleges of Agriculture, and farmers. It may be a revelation to the vast majority of people who don’t farm. After all, how can there be a problem, the grocery store is always full.
Le Couteur and Burreson (2003, p. 351) correctly suggest that historical events almost always have more than one cause. Each of the chemicals and chemical reactions included in this book is a fundamental part of the changes in US agriculture that contributed to its enormous productivity—the envy of the world. Development of the agricultural potential of each of the chemicals herein can properly be regarded as a historical event, but not one of them is the sole cause of modern agriculture’s productivity. Combined, there should be no debate that they have contributed significantly to the productivity of modern agriculture. Together they enabled farmers to achieve a greater degree of long-range predictive control over production and our food supply.
The agricultural revolution gave rise to early civilizations. However, science and technological advances are not always exclusively good. Diamond (1987) regarded settled agriculture as “the worst mistake in the history of the human race.” He does not discount the contributions of chemistry and science to increasing agricultural
Answer:
in the earlier period people were used two factors -
1 Iron plough - it is used in a large scale improvement over the wooden plough.
2 the practice of transplanting paddy that is growing sapling separately and then planting in fields.
