The agriculture minister, Matai Seremiah, described the country's export dilemmas at the Pacific Week of Agriculture conference in Port Vila.
Mr Seremiah said Vanuatu was running short of kava due to increased demand locally and internationally.
The recent El Nino weather pattern and 2015's Cyclone Pam compounded the shortage by curtailing production.
Islands Business reported plans to boost production of high quality kava were already underway.
On beef, Mr Nawalu said his ministry was continuing with plans to increase cattle numbers.
