How to Reduce Food Wastage?

I have made one Survey across India in which I found some Ideas about how we can conserve our Food.
Some of there Ideas are as follows :

• Make a small group that you can run successful for long time for the foods which is remaining at any party , conference, marriage, etc and collect that food and give it to them who really need and first search for some people who really need the food and do not give the food to the same person to whom you give it last.

• In a family, only that much food should be cooked as is required by the family. Cooking surplus results in wastage which is undesirable. Also, if the quantity cooked is too much, some of it should be kept aside and given to the needy if they are willing to take it.
•  Keep one person outside the main dining hole and give him responsibility to check dishes , if there is really proper reason regarding to quality of food then one can pass through gate otherwise tell him to finish his food then come back.
• In party, party organisers should estimate about the crowd and then prepare the food. Party organisers should tell their servents to serve small quantity of food, so that it will produce less food wastage.
•  The wasted food from all our homes(i.e. people living in a society) should be picked up by a person and then distributed among the needy.In this way the food wasted at our homes can be reduced to a greater extent.
• It happens where bulk cooking is going on...So at that places instead of Quantity of Food,Cooks should focus on Quality and Great Taste that people Eat the Last grain Of food as well.
• Extra food should be converted to compost by decomposition and used as fertilizer. To minimise food waste, appropriate quantity of food should be prepared and served.
• Try to improve the quality and take the food in less quantity even if you are too hungry. The wasted food can be collected and given to the people who needs it.
• Food collection from the functions like wedding and then distributing it to poor. 
• First a huge amount of awareness should be created among younsters. Food should be collected from functions by an organization and provided to the needy.
• Good food should be served and it is our duty to take as much as we want.If we have extra food,it should be given to the poor.
• Awareness of food wastage amongst citizen is most important step which should be taken for avoiding food wastage
