In the southern, central and eastern parts of Patna district the water level has declined in recent years, presently being more than 10 meters below ground level mbgl. Laser levelling has been shown to improve crop yields, reduce labour time spent weeding, and, in particular, reduce water use for irrigation by up to per cent.
Various socio-economic studies have confirmed these consequences.
This programme was adopted as a package programme as the very success of this programme depends upon adequate irrigation facilities, application of fertilizers, high yielding varieties of seeds, pesticides, insecticides etc.
One of these is shown in the above photo. This means food security could again become a Impact of green revolution on india as the population continues to grow rapidly. A Reverse Osmosis RO plant for treating local groundwater for drinking in a village in Bathinda district, Punjab Groundwater contamination due to indiscriminate application of fertilizers and pesticides in the agricultural fields is emerging as a serious threat in a number of Green Revolution states, Punjab being on the forefront.
Paddy fields at different stages of cropping cycle in Nellore district, Andhra Pradesh Apart from growing crop varieties unsuitable to the existing agro-climatic conditions, further drain on the valuable water resources, whether surface or groundwater, comes from multiple cropping of HYV varieties.
The writer is a professor and senior soil scientist at Punjab Agricultural University Published on. A dried up handpump due to overexploitation of groundwater for irrigation in Patna district, Bihar In Bihar, not only are handpumps drying up as result of declining water tables, but even high concentrations of naturally occuring contaminants, particularly arsenic and fluoride, is increasingly reported.
According to a Greenpeace study fromconducted in farms across the Malwa region, most wells were contaminated with nitrates, and 20 percent of all sampled wells had nitrate levels above the safety limit of 50 mg per litre as established by World Health Organisation WHO. Similarly, the production of rice which stood at In 2, In 3, with rate of 1.
In its production was Intensification of agriculture over the years has led to overall degradation of the fragile agro-ecosystem.
Indian farmers have now shown their intelligence to adopt latest techniques of production. The marine fish and prawns that reproduce in saline waters of sea and move to the lake afterwards can no longer migrate, while breeding of the estuarine species is no longer possible because these require a small amount of salt water for the purpose.
Distances between rural and urban centers came down.
This implies that the water requirement for paddy crop in such soil becomes much higher than the estimated litres ordinarily required for producing a kilogram of the grains. There are large disparities in the state-wise consumption of fertilizers with Punjab being ranked as number one with respect to its per-hectare use.
No other activity has such immense impact on the socio-economic development of the people as the Green Revolution. Moreover, only those areas having irrigation facilities and package of other inputs could achieve success in HYVP of wheat.
Agriculture has emerged as a lucrative occupation.
A few decades down the road, it is evident that the benefits of the Green Revolution are associated with unanticipated harmful effects of chemicals.
Norman Borlaug of Mexico developed new high yielding varieties of wheat and accordingly various countries started to apply this new variety with much promise. Further, failure or absence of canal irrigation has led to large-scale dependence on groundwater instead. However, the use of pesticides is known to seriously affect environment as a significant portion of the applied chemical actually enters water through surface runoff or through leaching, ending up in ponds, lakes, rivers, etc.Green Revolution, however, reached India finally in the s.
Since it involved almost all the crops including rice (which is a very important staple food in eastern and southern India) and it covered. The Green Revolution has led to reduced genetic diversity, increased vulnerability to pests, soil erosion, water shortages, reduced soil fertility, micronutrient deficiencies, soil contamination, reduced availability of nutritious food crops for the local population, the displacement of vast numbers of small farmers from their land, rural impoverishment.
Jul 09, · The Green Revolution 35 years on – what are the impacts in India? Green Revolution technology was first introduced to India from the USA in the s.
