Agriculture in Tonga contributes 16% of the country’s gross domestic product and, along with forestry, provides 44% of exports. More than 95% of Tonga’s agriculturally-active households engage in subsistence and semi-subsistence agriculture activity, and only 5% engage in commercial activities.

Established in Tonga in 2011, the PHAMA Program was designed to maintain and improve existing market access, and create new markets by developing the capacity of the public and private sectors to meet export market requirements.

The program transitioned to a new phase known as PHAMA Plus in 2018 and will continue until 2022. 

Priority areas identified for PHAMA Plus’ support in Tonga are root crops, specifically cassava, yam, taro and sweet potatoes, and horticultural produce including watermelon, squash, butternut and butterkin.
