Food security has been an issue of concern in many of the developing countries. In fact it can be said that the problems related to food security have been a major cause of concern to mankind. In the past the food needs of growing populations were met especially by expanding the cultivated area. There were farming communities that cultivated in a particular place for few years and then later abandon the land for several years. However, as the most fertile land became scarce, researchers and agriculturists found that expansion of agricultural land for increasing production was not a good option for the future years. Further expansion meant bringing poorer and lower yielding land into cultivation. Hence it was found in 1960s that the present levels of production cannot sustain the population and maintaining food production per capita was a challenging task (Evenson, N.D).
The Green Revolution came as a boon to mankind and was a major turning point in agriculture. It helped to increase the food production predominantly by getting better strains of wheat, rice, maize and other cereals in the 1960s. The revolution as such began in 1945 when the Rockefeller Foundation and the Mexican government established the Cooperative Wheat Research and Production Program to improve the agricultural output. Dr Norman Borlaug is the father of green revolution and was awarded the Nobel Peace Prize in 1970 for developing this technology (Parks, N.D.).
Green revolution is the breeding of new plant varieties and the application of modern agricultural techniques such as use of chemical fertilizers, irrigation, use of heavy machinery and control of pests and diseases using synthetic pesticides. Probably without the use of Green Revolution technologies the basic food requirements of the world's current population would not have been possible. This technology is responsible for saving almost a billion human lives from starvation (Easterbrook, 1997). Green revolution technologies along with its gains also brought about several economic and ecological problems. Food security being one of the most important issues concerning mankind, the further increase in food production should be addressed with caution in the coming years.
Benefits of Green Revolution
The adoption of HYVs occurred quickly because farmers and researchers found a good yield from these varieties when compared to the traditional varieties. By 1970, about 20 percent of the wheat area and 30 percent of the rice area in developing countries were planted with the HYVs, and by 1990, the share had increased to about 70 percent for both crops which produced good yield. In fact it can be said that the basic yields of rice and wheat almost doubled. For instance, Mexico a country that adopted green revolution went from having to import half its wheat to self-sufficiency by 1956 and, by 1964, to exporting half a million tons of ...Download file to see next pagesRead More

...Running Head: GREEN REVOLUTION Here] [Your Here] Here] [November 20th, Green Revolution The primary energy source used by my electric company is Nuclear power. It is apparent that the company generates power by Nuclear as the name of the company has “Nuclear Power” attached to it. When talking about ways to reduce energy use, there can be many steps taken. Some of the examples can be that if we use public transport we can reduce electric or if we use the common washing machines instead of the multipurpose ones; we can reduce some good amount of energy.

Absolutism: The Scientific Revolution and Agricultural Revolution

...Absolutism, The Scientific Revolution and Agricultural Revolution Absolutism, or absolute monarchy, is the granting of ultimate authority to a king or monarch who claimed to rule by divine right. Philosophers in the 1600s believed that God gave people kings to rule over them. Since kings received their power from God, they had absolute power and will answer to no one except God. Kings had the authority when it comes to creating laws and policies, domestic and foreign, imposing tax, pass justice, and control the country’s administrative system. As it was believed that the king’s power was granted by God, it was assumed that they are governing the people according to the will of God and so it was considered sacrilege to go against the king...

A Critical Evaluation of Workplace Diversity: Measuring the Intended Benefits of Managing Diversity

Diversity represents a wide spectrum of tangible characteristics and somewhat less-transparent personality-driven attributes which either contribute or detract from various social interactions in the workplace. 

With this definition in mind, managing diversity represents the elements of embracing and incorporating a wide variety of human differences (or commonalities) into the daily practice of business so as to provide enhanced benefit to the entire workplace and its processes. The goal of managing diversity is for leadership and subordinates alike to take a rather proactive approach to building enhanced inter-personal relationships and then applying this harmony to goals of higher productivity and teamwork.

English Test Evaluation

First of all, if all this in a test paper is inserted in a test paper, one must be careful to balance the number of items for a selected category. Second of all, the test has to have a medium length. For example, if the test is too short, the evaluation of the gained knowledge cannot be assessed properly. On the other hand, if the test is far too long, the students will become anxious and nervous and they will have the constant feeling that they cannot finish the test in time and get a high score. A moderate, but the various test could be the answer. The test should assess all the information given, but do it with a variety of items, that challenge imagination and that do not get the students in the state of frustration.

Effective and Ineffective Evaluation Tool

It has been an endless matter of debate for decades as to which methods reap effective results and which not.
One of the most effective tools for assessing students’ annual performance has to the one with a more comprehensive approach. The feedback by the teachers is very crucial for the students. It is the assessment plan which is developed by the teachers upon the on-going students’ achievements throughout the course and not merely upon the written traditional examinations1.

Feedbacks also help the students to engage in reflective, constructive and analy...

An Evaluation of the Role That the Principles of Behaviour Therapy Have to Play in Clinical Hypnosis

Hamburg (2006) first used this combined effort to treat two patients who were scared of dying. He uses his paper to encourage clinicians to refrain from not using their knowledge at the introductory classes of hypnosis but to go into it deeper. Many therapists at that time were taking the bold step of combining behavior therapy with hypnosis (Chaves, 2006). One group used hypnosis for desensitization therapy (Kirsch et al, 1995). However, there was general disagreement about the manner of hypnosis being employed and the methods of mentalist constructs. Chaves who strongly believed in the treatment combination used it as a base for many of his therapeutic interventions (Chaves, 1997a as cited in Chaves, 2006). The hypnotic therapy...

Evaluation of Children with Visual Impairment between Ages 4-12

A visually impaired child may suffer from incomplete sight, reduced vision, total blindness as well as legal sightlessness (Kelley and Gale p 45). It is a condition that may become severe in a child, thereby affecting its growth and development. The impact is usually dependent on the kind of loss, age at which it occurs, as well as the general body functioning of the child. The normal interest that is usually evident amongst children on seeing attractive items in their surroundings lacks in a visually impaired child. This may interfere with the child’s learning capabilities unless he/she is assisted to learn. The development of social behavior in children usually depends on the ability to see parents or those in charge of ca...
