Describe one challenge to food production in Vietnam:

• Climate change is happening, the greater challenge for humanity on food security and poverty. People can be hungry due to drought, floods, and falling into poverty. Our agricultural production is excessive not because the markets do not need the products but because we do not produce the new products that the market requires. The situation is ore difficult through the appearance of new agricultural exporters. They are competing hardly with us in our traditional markets.
• Severe weather changes constantly. Production level is backward, people are not aware of  the important part of food production in our country. They unknown application of scientific advances in the production techniques.
