Dodds Prison is aiming to boost its food security and maintain a high level of food self-sufficiency, farm manager Valiance Holder said on Tuesday.In addition to a plan to acquire two greenhouses, he said efforts were underway to expand crop and livestock production.Following the graduation ceremony for five inmates and five prison officers who completed an aquaculture farming course, Holder told Barbados TODAY that about 90 per cent of the produce grown at the facility in St Philip is used at the prison.Sweet potatoes, cassavas, yams, pumpkins, cucumbers, carrots, squash, tomatoes, watermelons, chives, parsley, turmeric, and marjoram are planted on a ten to 12-acre plot of land, while Blackbelly sheep, Landrace and Large White (breeds of pigs) and Redpoll cows are also reared on the compound.Holder said plans were in train to restart raising broilers.
