Question

how food security is important for sustainable development of nation?

Answer 1

Threats to global food security present a challenge that most agree is only getting worse. The possibility of achieving a food secure world without sustainable development is highly debated in policy and academia. A recently published article in the journal of Public Health Nutrition explores this notion along with the evolution of food security from the 1970s to present day. In an analysis of more than 80 articles, the authors posit that one cannot exist without the other. This conclusion sheds light on previously unidentified challenges to food security, such as rural transportation, infrastructure, and even our diets.
 
The concept of food security has grown over time. In the 1970s the focused was solely on supply due to the extreme instability of agricultural commodity prices. Over time, it expanded to include food access and nutrition, embracing the critical needs of vulnerable populations. By 2001, the definition of food security had adopted nutrition and evolved to its most present definition: a situation that exists when all people, at all times, have physical, social and economic access to sufficient, safe and nutritious food that meets their dietary needs and food preferences for an active and healthy life.
