. Food diversification policy can not be separated from dry land empowerment program, as dry land was a major producer of food alternatives to rice. However, the fertile dry land area is getting limited, so the suboptimal upland as an alternative. Therefore, it is necessary technological innovation to overcome suboptimal land limiting factor, so it can be utilized to the development of agriculture especially for food crops. This paper discusses the effort to empower sub-optimal dry land to support food diversification policy, the discussion includes the potency of sub-optimal upland for food crop development, the main constraints of suboptimal dry land for food crop development, and various technological innovation to empower land management and optimization of suboptimal upland as support food security.
