Most farmers in Cambodia grow rice. Many also may grow cassava and maize. But very few farmers in the country grow other vegetables. And more Cambodians are demanding organic produce.
    (5)A recent study from the World Bank shows strong growth in Cambodia’s agriculture industry. This has helped reduce the number of people in poverty from seven million in 2007 to three million in 2012.
   Part of this growth has come from increased land cultivation for rice farming. But growth has slowed in the past two years. (6)The World Bank says farmers need to increase their yields and grow more kinds of crops, such as vegetables. The bank says vegetables earn average returns of $ 1 575 per hectare for small farmers. This compares to $ 544 per hectare of cassava and only $ 307 per hectare of rice.
    (7)An expert says it will be difficult for farmers to change crops. Many of them may lack the skills, technology and investment money to grow vegetables. Most vegetables sold in Cambodia are imported from Vietnam and Thailand. The local competition means that there are no quick gains for Cambodian farmers.
