The Green Revolution took place in agriculture in several developing countries due to severe food shortages caused by intensive population growth. It covers the period from the 40s to the 70s of the last century and is associated with the widespread use of new technologies in agriculture.
Features of the "green revolution"
The need for a green revolution in developing countries was caused, first of all, by a small amount of land and a large number of people. Such an imbalance threatened mass death of people from hunger. At that time, it was necessary to take some constructive solution to the acute problem of hunger.
The Green Revolution began in Mexico with the development of new varieties of grain crops that are more resistant to the local climate and their further large-scale cultivation. Mexicans cultivated several high-yielding varieties of wheat. Further, the "green revolution" swept the Philippines, South Asia, India, etc. In these countries, in addition to wheat, rice, corn and some other crops were grown. At the same time, rice and wheat were the main ones.
Manufacturers used improved irrigation systems, since only a stably supplied and sufficient amount of water can ensure normal crop growth. In addition, the process of planting and harvesting was maximally mechanized, although human labor was still used in places. Also, in order to improve quality and protect against pests in acceptable quantities, various pesticides and fertilizers have been used.
