Livestock became less prevalent because of how hard it was to maintain them, due to little grazing land available. Also the urban areas growing in size, to accommodate the increase in population in the areas. The yield per hectare of sugarcane crossed 60 tonnes per hectare in 1960-61 from 65 tonnes per hectare in 1990-91. Soil organic matter levels are declining and the use of chemical inputs is intensifying. They have multiplied their material assets, improved their caloric intake and overall standard of living. Due to population increase per capita income and per capita food availability has reduced.
However, the people who invested in crop agriculture were making big profits from these lands. Organochlorines , lindane etc 3. In India, for example, lower income groups often pay more than the rich for the cereal foods that make up so much of their diet Cleaver, 183. Newly introduced crop varieties have been responsive to inputs but this has necessitated both increased fertiliser application and use of irrigation resulting in water contamination by nitrate and phosphate and changes in the ground water table. The increased rate of soil erosion is not only affecting the areas from which soil is being removed, but also the areas in which it is deposited. The associated industries have created quite a large volume of transportation, marketing and food processing requirements.
In 1956 Mexico became self sufficient in wheat production and by 1963 it became a grain exporting country. Thanks for validating our work, really great post. The living conditions for the people of India and third world countries seemed to have changed to follow the technology and free market approach. The Green Revolution program, which began decades ago, had a noble goal -- increase the global food supply and reduce world hunger. In the post-Green Revolution period farmers also planted eucalyptus and poplar trees along the borders of their fields. The uneven regional growth was mainly responsible for the low absorption of labour within agriculture. Increase in Per Hectare Yield: With the adoption of modern technology, the yield per hectare has also shown considerable improvement.
Enlargement of Production Function: The new agricultural strategy green revolution has proved that more can be produced with the same resources. During this time period, new chemical fertilizers and synthetic herbicides and pesticides were created. Nitrate pollution is regarded as the major factor for blue baby syndrome. Traditional crops have the highest gene diversity and as they dwindle, those genes vanish. In order to help the farmers out with the increase in the cost of the new technologies, many governments allowed for farmers to take out loans and use a credit system.
These people would work and live at their jobs for about 5-6 months, then come back to their village to help them with agricultural work. Although the farmers specifically were not government members, they had political influence. Weeds or crop remains that harbour pests can be destroyed, planting and harvesting dates modified, crops rotated and several crops are sown together. These observed effects have invoked a great debate about whether the green revolution hurt the lower class and rural people with the population growth and the growth of agriculture or if it benefitted them. As a result of high-yielding varieties of wheat the production of wheat rose to high level of 5000 to 6000 kg. All these efforts of the Government led to a rapid improvement in productivity of different crops as shown The following in table: This Table shows that except pulses, average yield mostly rice and wheat per hectare has improved significantly due to new technology.
The farmers are aware of this fact and they often complain about the need of more inputs every year to get good returns from their lands. In the 1970s, all of India was in a state of major migration. Many industries producing agriculture, machinery, chemical fertilizers, pesticides, insecticides etc. In order to minimize the danger of soil erosion, the government and the farmers have taken a number of steps. Traces of lead, copper, zinc, cadmium and arsenic were also detected in rice, wheat, maize, mustard, cotton, sesame, fruits and vegetables.
The negative impact of the Green Revolution includes: 1. If scientific transformation in the cropping patterns and irrigation practices are not made, more agricultural land may become unproductive. . The promise of low-cost credit rises in production levels and increased income for small-scale farmers was proved false. If the tube-well irrigation continues for the supply of moisture to the crops like rice and vegetables, the apprehension is that the underground water table may not be in a position to recharge.
Frequent Occurrence of Famines The Bengal Famine 1943 the world's worst recorded food disaster. The less productive soils, deficient in humus are generally more vulnerable to soil erosion. It is this lack of money that has sent many of them into poverty and even cost them their jobs. The average annual production of rice rose from 35. The landless workers are now having more employment opportunities in agriculture, agro-based industries and other ancillary activities.
