You are posted as head of district which is severely affected by water crisis. The situation has worsened to the extent that it has disrupted the law and order. Presently cricket tournament is going on in the country. Matches are held all over the country. You get a call from the state cricket association that a cricket match is to be held in your district. A good sum of money is offered for the match. However when you discuss the matter with your colleagues they suggest you to decline the offer as the district is facing severe water scarcity and this would further add to the problem as a large volume of water will be needed for irrigating the pitch. If you accept the offer, you would get a good sum of money which would compensate for the water used for irrigating the pitch. ¤ Will you accept the offer? ¤ What are options before you? Explain the merits and demerits of each option. ¤ Also suggest what course of action will you take?
