Selection of rice varieties and cultivation methods for reducing rice contamination in Bangladesh, and approaches to the spread of such information

Research grant

Project Description

In Bangladesh, the use of water from rivers contaminated with arsenic contaminated ground water and industrial wastewater on agricultural lands is leading to the contamination of rice and causing health issues for the people of Bangladesh. In order to reduce the health risks associated with rice contamination in Bangladesh, this research, through field-based testing, will evaluate and select rice varieties which enable a reduction in heavy metals in rice grains without loss of production volumes or nutritional value, as well as considering and selecting the ideal cultivation management method. Additionally, a quantitative evaluation will be carried out on the degree to which the selected rice variety and cultivation management method can reduce health risk to the people of Bangladesh, thereby helping to address social issues currently faced by the country.
