Bhagat Singh : True Face of FEARLESSNESS

Bhagat Singh was a prominent freedom fighter of India. The courage with which Bhagat Singh fought the mighty British government for the independence of the country is a great role model for the youth of today. He also refused to run away by throwing a bomb in the Central Parliament (Central Assembly). As a result of which he was hanged on 23 March 1931 along with his two other companions, Rajguru and Sukhdev. The whole country remembered his sacrifice very seriously. First the Saunders-Slaughter in Lahore and then the Explosion of the Central Assembly in Delhi with Chandrashekhar Azad and other members of the Party gave rise to an open rebellion against the British Empire. Bhagat Singh was interested in anarchist and Marxist ideology. Early Life: Bhagat Singh was born on 27 September 1907. His father's name was Sardar Kishan Singh and mother's name was Vidyavati Kaur. It was a Sikh family. The Jallianwala Bagh massacre that took place in Amritsar on April 13, 1919 had a profoun

SOIL DEGRADATION

 

 The nation that destroys its soil, destroys itself

~ Franklin D. Roosevelt

What is soil degradation-

Soil degradation is the decline in soil condition caused by its improper use or poor management, usually for agricultural, industrial or urban purposes.

Causes of soil degradation-

The loss of farm land has been caused by a number of factors,

many or most of which are tied to human development. The primary causes are:

·         Deforestation

·         Overgrazing

·         Overexploitation for fuel wood

·         Agricultural activities

·         Increased flooding

·         Industrialization.


The following figure illustrates the relative sizes of the causal mechanism as a function of region


          On the global basis, the soil degradation is caused primarily by overgrazing (35%), agricultural activities (28%), deforestation (30%), over exploitation of land to produce fuel wood (7%), and industrialization (4%).

 

The main reasons for unproductiveness or degradation of soils are as follows:

1. Nutrient disorder

2. Water-logging

3. Salinity

4. Erosion

5. Biological degradation

6. Other causes

Impact of Soil Degradation:

The following are the impacts of soil degradation:

 

1. Degradation leads to reduction in crop yield in the affected lands and a possible decline in cropping intensity.

2. In extreme cases, soil becomes unfit for cultivation.

3. Silting of drainage, canals, rivers and reservoirs results in increased floods and droughts.

4. In some cases farmers use more fertilizer inputs to compensate reduced soil productivity while in other cases, they use excess fertilizers.

5. The rate of siltation in many water reservoirs are significantly high. According to Central Water Commission (1991), nearly 11 per cent of the total capacity of water reservoirs has been silted.

6. Soil degradation has several adverse impacts on the environment. It affects global climate through alterations in water cycle and energy balances and disruptions of carbon, nitrogen and sulfur cycles.

The estimated annual loss of different crops due to soil degradation ranges from Rs. 89 billion to 232 billion which represent a loss of 11 to 26 per cent yield.

Control of erosion-

(Adapted from ACS Distance Education 2009)

As erosion is caused by the effects of wind and water, control methods are generally aimed at modifying these effects. The following list describes some of the most common control methods:

·         Prevention of soil detachment by the use of cover materials such as plants.

·         Crop production techniques (e.g. fertilizing with organic fertilizer), to improve soil characteristics and promote plant growth and hence surface cover.

·         Ploughing to destroy rills and contour planting to create small dams across a field, to retard or impound water flow.

·         Filling small gullies with mechanical equipment or conversion into a protected or grassed waterway.

·         Terracing of slopes to reduce rates of runoff.

·         Prevention of erosion in the first place by careful selection of land use practices.

·         Conservation tillage methods.

·         Armoring of channels with rocks, tires, concrete and timber to prevent bank erosion.

·         The use of wind breaks to modify wind action.

·         Ploughing into clod sizes too big to be eroded, or ploughing into ridges.

Conclusion-

People can be a major asset in reversing a trend towards degradation. However, they need to be healthy and politically and economically motivated to care for the land as subsistence agriculture, poverty, and illiteracy can lead important causes of land and environmental degradation especially in Zambia which has inadequate laws and policies aimed directly at preventing land degradation.

Doctrine of Notional Extension under the Workmen Compensation Act, 1923

  There is no problem in detecting that the accident occurred in the course of employment when a workman is injured in the working place and in the working hour and doing his duty. The problem arises when these elements do not coincide together. But a workmen if injured just near the work premises or just before joining the work or in the way to work problem arises. To address this kind of problem and giving some kind of relief to the workmen the theory of notional extension evolved. “As a rule, the employment of a workman does not commence until he has reached the place of employment and does not continue when he has left the place of employment, the journey to and from the place of employment being excluded. It is now well-settled, however, that this is subject to the theory of notional extension of the employer’s premises so as to include an area which the workman passes and repasses in going to and in leaving the actual place of work. There may be some reasonable extension in bot

Peace - A Way Of Life

To be peaceful is the sign of a conqueror.  We have often heard people saying 'follow the path of peace and you will be happy', 'preach peace' and many other phrases emphasising on a way of living- Peace. But what is it really about?  With reference of the holy Bible, peace is defined with notions like  totality or completeness, success, fulfillment, wholeness, harmony, security and well being.  The definition of peace changes with mindsets of people. For one, it is a sense of accomplishment, non- violence for another, salvation to a few and a lot more to others. But what peace exactly is? And how can we attain it? Peace is acceptance. A vision of seeing things and extracting optimism out of it. Peace makes life easier. To be satisfied is what peace is. To be able to look back at your life and accept all its darks and jewels is what peace feels like. Peace is a state of mind where your soul feels calm, free from the dirt of hatred, negativity, criticism, inferiority and
