Agriculture and the problem of overpopulation in India

The Green Revolution

When the population of a country grows so fast that it cannot produce sufficient food in the long run, it eventually leads to famine. India is such a country that could not succeed in feeding its entire population, for it is overpopulated to the worst degree, while primitive farming methods have caused the country’s crops to be of the lowest in the world. In an effort to align the production of food with the growing population, they have over the past thirty years tried to apply the so-called Green Revolution in India. The Green Revolution is based on the increased productivity of already cultivated land. This is achieved by the application of bigger amount of fertiliser and the cultivation of new crops. Training programmes have been developed to introduce inhabitants in rural areas to new ideas, farming methods and techniques. New wheat, rice and maize varieties were also developed which produced more seed, yielded higher crops, reacted better to the application of fertilisers, and contained more proteïn.

The effective use of fertilisers did not increase only the agricultural production, but also the water capacity of the soil.

Chemical as well as organic fertilisers were applied.

Consequently there was a total increase in the production that was slightly higher than the annual population growth. Several record grain crops were yielded from time to time.

Although the objectives of the Green Revolution were realistic and attainable, several problems regarding their application are still being encountered thirty years later.

The extremely conservative peasant farmers are very traditional in their ways, so that and renewal and change are met with scepticism and bias.

Most peasant farmers are still illiterate.

The peasant farmers are poor and cannot afford farming implements, insecticides, pesticides and fertiliser.

The Green Revolution is an expensive programme and there is a lack of capital for meeting the costs. The country increasingly relies on loans from abroad to pay for their programmes.

The only way to make the Green Revolution succeed, is to ensure that a balance is maintained between the growing population and the production of food. The population growth needs to be carefully controlled and planned.

To establish if famine can be avoided by applying technological development

[lo 2.2]

Do we need technology to beat famine?

Study the following notes and use them as a basis to answer the above question in your own words.

yes:

There is no doubt that genetically manipulated seed yields higher crops. The Green Revolution has made a difference – experience and statistics have proved this.

It is therefore a tried and tested way to produce larger amounts of food over a short period.

anybody can imagine what will be happen after 100 years from now in nano tech world
Prasenjit
after 100 year this will be not nanotechnology maybe this technology name will be change . maybe aftet 100 year . we work on electron lable practically about its properties and behaviour by the different instruments
Azam
name doesn't matter , whatever it will be change... I'm taking about effect on circumstances of the microscopic world
Prasenjit
how hard could it be to apply nanotechnology against viral infections such HIV or Ebola?
Damian
silver nanoparticles could handle the job?

Hello
Uday
I'm interested in Nanotube
Uday
this technology will not going on for the long time , so I'm thinking about femtotechnology 10^-15
Prasenjit
can nanotechnology change the direction of the face of the world
Prasenjit Reply
At high concentrations (>0.01 M), the relation between absorptivity coefficient and absorbance is no longer linear. This is due to the electrostatic interactions between the quantum dots in close proximity. If the concentration of the solution is high, another effect that is seen is the scattering of light from the large number of quantum dots. This assumption only works at low concentrations of the analyte. Presence of stray light.

the Beer law works very well for dilute solutions but fails for very high concentrations. why?
