Technology Specifics Key to Efficient Risk Assessment, Says ExpertsDecember 1, 2022
Risk assessments are part of an evaluation process when developing and implementing new technologies. In the case of gene drives, risk assessments should be done on a case-by-case basis under context-specific considerations and backed by scientific evidence, according to experts.
Owain Edwards, Group Leader at the Environmental and Synthetic Genomics, CSIRO Land and Water, defines risk assessment as determining the likelihood of unintended consequences when releasing a technology, such as genetic modification and gene drives, in the environment.
Every organism is different in terms of its behavior, biology, genetics, and genome. For this reason, risk assessments should be context-specific and done on a case-by-case basis, says Brinda Dass, Policy Lead for Gene Drive Research at the Foundation for the National Institutes of Health.
Evaluators must consider the technology, how it functions, the proposed method of use, and the environment in which it will be released into. It is also vital to weigh the benefits of the new technology against the risks it can bring, and take into consideration the risks of other available tools used for the same purpose.
In the case of gene drive for malaria control, Shaibal Dasgupta, Group Leader at the IATA Institute for Genetics and Society, notes that mosquitoes are not key species in the ecosystem; therefore, risk assessment should cover their potential to change their disease-carrying behaviors rather than their ecological impacts.
