An example is the decision to concentrate effort on the expansion of land available for rice and maize such as the proposed reclamation of 300,000 ha of tidal lands in the West Coast area and the bringing into cultivation of a further 200,000 ha of arable land elsewhere. Its function is to supply materials according to the plan. It does not do the physical distribution itself but works through the State Planning Commission and its national, provincial and county transport companies. Such arrangements demonstrate the complexity of the arrangements for the organization of production. AMSD plays a merely administrative, logistics management role, relying on the CPD and the APD for technical .instructions.
Construction includes reservoirs, drainage, river and lake and field irrigation.
Maintenance section includes equipment, tidal wall protection, maintenance of lakes and rivers, field irrigation and water management. Given the importance of irrigation in the agricultural sector, this is a small office in marked contrast to the often massive irrigation Departments of some neighboring countries such as the National Irrigation Administration in the Philippines and the Royal Irrigation Department in Thailand. There are several reasons of this. First the rice areas have been served fairly comprehensively by irrigation for some time and no major new schemes are required. Secondly, for minor development or improvement, the counterpart offices at provincial and county level are responsible.
