The preliminary findings of a report on nutrition and food systems were presented at an international seminar on sustainable food security and nutrition under agriculture transformation and urbanization on May 26.

According to the findings current social dietary patterns are changing and face serious challenges: growing demand, poor-quality of intake -- more sugar but fewer fruits and vegetables -- and expensive food supplies that may not be sustainable.

Professor Jessica Fanzo, head of the High Level Panel of Experts (HLPE) project team that conducted the research, explained that climate change has reduced food supplies.

What's worse, increasing population pressure and urbanization have led to a decrease of cultivated areas, which results in even lower food production and unhealthy population conditions.

One example of such a condition is obesity, which, although perhaps easily ignored, is increasingly prevalent according to the World Health Organization.

China is now 57 percent urbanized, a figure that will reach 70 percent by 2050.

"Urbanization changes nutrition. When a country gets wealthier, it urbanizes and when a country urbanizes, (its people) get fatter," Professor Fanzo said.

Such problems have appeared not only in China but also in the rest of the world. "No country has been able to stop the obesity trend from going up," she added.

To help people fight obesity and re-gain a healthy and nutritious diet, Professor Fanzo suggests "Food system can shape consumer demands."

"We need to keep in mind that we have trade, agriculture and subsidies policies and we have the power to shape supply," she stressed.

At the seminar, Zhang Lubiao, deputy-director general of the Department of International Cooperation, Ministry of Agriculture, suggested the importance of innovative technologies for agriculture development.

"Food production will not meet demand by 2035 or 2050 without advanced technology," Zhang said, "We also need innovations in management. Without investment, we can’t make agriculture big."

He also mentioned that China has been devoted to food security and nutrition advancement and will keep offering investment, training and extension of agriculture demonstration centers to other developing countries.
