1.2 CONCEPTS TO REMEMBER<br />

Alternative Cropping Pattern<br />

It is important to adopt crop stabilization strategies to cope with<br />

drought situation. These are techniques that involve use of different<br />

crops such as drought resistant varieties in different seasons <strong>and</strong> also<br />

within <strong>the</strong> same seasons. So if one crop fails, <strong>the</strong> o<strong>the</strong>r could blossom.<br />

It is a curved structure in a building supporting itself over open space<br />

by pressure of stones one against <strong>the</strong> o<strong>the</strong>r.<br />

Condition Assessment<br />

Canal Irrigation<br />

Canal Irrigation is one of <strong>the</strong> ways to compensate <strong>the</strong> losses<br />

caused to irrigation due to disasters. Larger canal systems enable<br />

<strong>the</strong> transfer of water from one region to ano<strong>the</strong>r, which has many<br />

advantages. For instance, a region suffering from drought or low<br />

rainfall could receive water from ano<strong>the</strong>r region, which has had<br />

better or abundant rainfall. Large-scale canal irrigation is usually<br />

linked to a storage reservoir or a barrage/weir in a river.<br />

It implies recording of damages <strong>and</strong> finding out <strong>the</strong> causes of distress. Through this type of assessment,<br />

we can estimate <strong>the</strong> residual strengths of structural components <strong>and</strong> <strong>the</strong> system including <strong>the</strong> foundation.<br />

We can also plan <strong>the</strong> rehabilitation <strong>and</strong> retrofitting of <strong>the</strong> buildings.<br />

The essence of Crop Life Saving Technique is water harvesting <strong>and</strong> moisture stress alleviating<br />

practices. Short duration crops like grams, mustard <strong>and</strong> pulses can be very well intermixed with<br />

o<strong>the</strong>rs like sorghum <strong>and</strong> wheat. Some crops like bajra <strong>and</strong> jowar need less water than rabi <strong>and</strong><br />

groundnut. They have to be chosen as per wea<strong>the</strong>r conditions. Crop saving techniques could be of<br />

many types:<br />

Deforestation<br />

It refers to <strong>the</strong> process of continuous felling of<br />

trees <strong>and</strong> o<strong>the</strong>r plantation in <strong>the</strong> forests due to<br />

man-made <strong>and</strong> natural causes.<br />
