These issues raise new questions as to how demandswill be met in future in future, even with a slowing down of population growth .Today,the world is seeling a changing trend in dietayhabits .As living standards are improving ,people are eating more non-vegeteraian food.As people change from eating grain to meat ,the world's demand for feed for livestock ,base on agriculture ,increases as well ,This uses more land per unit of food produced and the result is that the world's poor do not get enough to eat.
Women play an extremely vital role in food productin as well as in cooking meals and feeding children.In most rural communities they have the least exposure to technical training and to health workers trained in teaching/learning on issues related to nutritional aspects,women and girls frequently recieve less food than the men .These disparties need to be corrected .
In India there is a shortage of cltivatable productive land.Thus,farm sizes are too small too support a family on farm produce alone.with each generation famrs are being subdivivded further.poor environmental agricultural practices such as slash and burn ,shifitng cultivation or rab cultivation degrade the forests .
Globally ,5 to 7 million half of famland degraded eacj year.The loss of nutrients and the overuse of agricultural chemicals are major factors in land degradation.water scarcity is an important aspect of [ppr agricultural outputs.Salinization and water]-logging has aggected a large amount of agriculture worldwide.
The loss of genentic diversity in crop plants is another issue that is leading to a fall in agriculturral produce.Rice,wheat and corn are the staple foods of two-thirds of the world's grasslands,wetlands and other natural habitats are being lost ,the ability to enhance traits that are resistant to diseases,slinity,etc.,is also being lost.Genetic enginering is an untried and risky alternative to traditional cross-breeding.
