As the problem arises it solution is also explored. I think in such situations hydroponics, aeroponics  and plant biotechnology would be extremely helpful in meeting the food and nutritional securities of the growing population.

Especially in peri-urban areas much agricultural land is lost by land use changes to residential and commercial / industrial development. Depending on the situation of the region involved it can create challenges to food production and food security, although the latter one is more complex than just considering food production alone; her eequally, if not even more important is access to food which often is a function of food prices and people's income.
