Farmers must work with the government and come up with alternatives to the willing-buyer, willing-seller policy, Agriculture Minister Tina Joemat-Pettersson said on Tuesday.

She acknowledged the policy was not working, but emphasised this did not mean she supported land nationalisation, her spokesman Rams Mabote said.

He was commenting after she addressed an AgriSA policy conference in Stellenbosch in the Western Cape.

Mabote said the minister indicated she planned on raising the nationalisation issue at the African National Congress's policy conference in June.

In her address on Tuesday, Joemat-Pettersson also spoke of the importance of unity and clear communication between government and farmers, in order to stabilise the commercial farming sector.
