Green Revolution: Impacts, limits, and the path ahead

green revolution and its impact on environment

Finally, at the global level, there has been an increased tightening of food markets driven by population and income growth as well as diversion of food grain for biofuel and livestock feed. Adoption of improved varieties across sub-Saharan Africa reached 70% for wheat, 45% for maize, 26% for rice, 19% for cassava, and 15% for sorghum by 2005. The Green Revolution reduced production costs and prices of food. In 1956 Mexico became self sufficient in wheat production and by 1963 it became a grain exporting country. The chemicals can seep into groundwater and pollute it.

He introduced this variety of wheat in Mexico and within twenty years the production of wheat had tripled. There is also a growing body of evidence of spillovers from the productive regions that benefit the more marginal environments. The land carrying capacity status was deficit. As we now know, as a result of advances in agricultural technology, commercial farms were able to produce more food and sell it at lower prices. Borlaug an American scientists Plant pathologists who was quietly been working for years on new agriculture techniques in Mexico Norin 10 a semi dwarf variety from Japan with some Italian varieties, was used by Dr.

This is demonstrated by the fact that from 1961 to 2008, as the human population increased by 100% and the production of food rose by 150%, the amount of forests and natural land converted to farm only increased by 10%. This role requires policies that i emphasize agriculture as an engine of growth and poverty reduction, ii enhance competitiveness of modernizing agricultural systems, and iii focus on sustaining the resource base by correcting distortions that create incentives for unsustainable use. While many pesticides used in organic farming are safer than common chemicals we come into contact with every day, it is important to be careful. For example, the removal of pesticide subsides in Indonesia in the early 1990s led to a dramatic drop in insecticide use ,. Thus, in other words this new technology is known as Package Programme, i.

This paper analyzes the pollutants generated from the manure of the five principal commercial animals in different farming practices. The harvest index refers to the above ground weight of the plant. The Green Revolution was a period when the productivity of global agriculture increased drastically as a result of new advances. The growth of output was also slow to generate adequate employment opportunities. The emphasis of global public good research in resource management must be on such strategic knowledge generation rather than development of location-specific techniques and products. The sudden rise in the demand for labour in these areas induced mechanisation and labour-saving practices in general. After year 2000, F-, Cu, Fe, Pb, Cr and Cd became beyond permissible limit.

It was 71% in case of cereals, 104% for wheat and 52% for paddy over the period 1965-66 and 1989-90. Analysis revealed the presence of lindane in less than 1 % of milk samples. Father Green Revolution became successful in irrigated areas whereas in the rained belt the new technology couldn't be properly implemented. Monitoring of 210 bovine milk samples collected from local markets in the Nadia district of West Bengal during 2011 was performed. At the country level, public policy can play an important role in ensuring that new innovations reach and benefit smallholders and encouraging the sustainable use of natural resources.

Various scientific studies and surveys conducted on fertilizer and pesticide residues during last 45 years indicate the presence of residues of fertilizers and pesticides like nitrates, organochlorines, organophosphates, synthetic pyrethroids and carbamates at higher level than permissible limit in milk, dairy products, water, fodder, livestock feeds and other food products. In the years since intensifying its agriculture, India has added several hundred million more people and continues to suffer widespread poverty and hunger. The term Green Revolution refers to the renovation of agricultural practices beginning in Mexico in the 1940s. Irrigation also played a large role in the Green Revolution and this forever changed the areas where various crops can be grown. Moreover, the beef cattle exert the largest environmental impact for unitary production, about 2-3 times of pork and 5-20 times of chicken. These substances are harmful and can cause serious health problems. Because of its success in producing more agricultural products there, Green Revolution technologies spread worldwide in the 1950s and 1960s, significantly increasing the amount of calories produced per acre of agriculture.

This was introduced by M S Swaminathan in India. There is a large econometric literature that uses cross-country or time series data to estimate the relationship between agricultural productivity growth and poverty. In India, it is estimated that a 1% increase in agricultural value added per hectare leads to a 0. The Disadvantages of the Green Revolution are- 1. For instance, in eastern and southern Africa, the amount of arable land has risen only marginally, but the percentage of households engaged in agriculture has grown threefold. The use of chemical fertilizers and synthetic herbicides and pesticides dramatically influenced the environment by increasing pollution and erosion.

Increase in productivity in these areas has enhanced the status of agriculture from a low level subsistence activity to a money- making activity. During this time period, the amount of crops produced rose due to the introduction of chemical fertilizers and synthetic herbicides and pesticides. Yields growth for roots and tubers rose sharply between 1980 and 2005, increasing 40% during this period. The Pakistan and India were the first South Asian nation to use these varieties. Feed is a main factor of sustainable livestock population, where the availability of suitable land for grass growth is urgent. One primary mission of the Green Revolution was to improve the production of wheat and rice -- two high-yield plants. Organochlorines , lindane etc 3.

The attitude of the Government towards the problems of treatment and rehabilitation of victims of accidents on farm machines is that of total ambivalence. More recent evidence does suggest that diets are shifting in urban and rural Asia to include fewer cereals and more milk, meat, vegetables, and fruits. Less than 15% of land had low water carrying capacity. These new farming techniques and advances in agricultural technology were utilized by farmers all over the world, and when combined, intensified the results of the Green Revolution. They may also harm the environment by using too many of those products.

Increasing Population's Carrying Capacity: Critics argue that the Green Revolution has temporarily increased the carrying capacity of a population thus allowing the population to grow. Output price protection and input subsides—especially fertilizer, pesticide, and irrigation water—distorted incentives at the farm level for adopting practices that would enhance efficiency in input use and thereby, contribute to sustaining the agricultural resource base. The pesticides cover a wide range of compounds including insecticides, fungicides, herbicides, rodenticides, molluscicides, nematicides, plant growth regulators and others. Increasing cereal productivity not only meets demand for staples, it also allows for the release of land to diversify into high-value crops and movement of labor out of agriculture, where other economic opportunities provide greater returns. Furthermore, a probusiness policy environment that includes intellectual property protection, reduced trade barriers, and a transparent biosafety procedure will lead to additional private sector research investments in the emerging economies. As these studies show, there is evidence of continuing high rates of return for crop breeding improvements that have wide adaptability, such as those improvements for wheat, rice and maize.
