South Africa marked International Day of Plant Health on Tuesday, 12 May, with renewed calls for stronger biosecurity measures to protect crops, food systems and rural livelihoods from destructive pests and diseases.
The department of agriculture, together with the Mpumalanga department of agriculture, rural development, land and environmental affairs, commemorated the day in Mbombela under the global theme “Plant biosecurity for food security and nutrition”.
Agriculture minister John Steenhuisen used the occasion to stress the direct connection between healthy plants and national food security.
“Plant biosecurity is active involvement. Fighting plant pests and diseases today secures food security for tomorrow for animals and humans,” Steenhuisen said.
“By strengthening plant biosecurity, we are locking the doors against devastating pests and securing the nutrition, livelihoods and future for all South Africans. Protecting plants today is the only way to feed tomorrow.”

Plants make up around 80% of the food consumed globally and are also a major source of oxygen, yet they remain under constant threat from invasive pests and diseases.
According to the Food and Agriculture Organisation of the United Nations, up to 40% of global food crops are destroyed every year by pests and diseases.
Speaking during the commemoration, Dipepeneneng Serage, deputy director-general for agricultural production, biosecurity and natural resources management, said plant protection could not rest solely on the shoulders of government or farmers.
“Protecting plants is not just the responsibility of farmers or government or scientists, or an agricultural issue, but a shared responsibility. It is a national and global responsibility,” said Serage.

Serage said the department plans to strengthen collaboration with universities, the Agricultural Research Council, provincial governments, municipalities, traditional leaders and the private sector to improve plant biosecurity systems across the country.
