The country imports the vast majority of its fruit and vegetables. Only 6% of the fruit and vegetables served in its schools is grown in Wales, the BBC reported.
Droughts and wildfires this summer were a wake-up call, and winter flooding could leave Wales' food supply vulnerable, an expert has warned.
Wales needs to grow more fruit and vegetables or it will be at the mercy of wars and climate change, the expert said.
Despite 90% of Wales being used for agriculture, only about 0.1% is used for horticulture, the BBC said, citing official surveys.
Fisher, referencing the appeal to grow more produce at home, said the UK"has an incredibly centralised food system with 95% of the food we eat bought from nine supermarkets".
She does not believe it will necessarily be as bad every year, but she accepts there will be more hot summers and unpredictable weather such as flooding.
"There will also be a focus on how to grow more fruit and vegetables in Wales, and we have already begun mapping the current position of the sector with key stakeholders,"a spokesperson said.
