145 Wahyunto et al. low fertility), eh (slope/erosion hazard), oa (oxygen availability /poor drainage), rc (rooting condition), fh (flood hazard/ water inundation), ps (peaty soil). For example the result of land evaluation is (S)3,nr means that the land (S)3 is marginally suited due to low nutrient availability. Land suitability evaluation resulted in 28 Physiographic Mapping Unit (PMU) are as follows: PMU 1 was dominated by recent sand beach and thus is not suitable (N) for any kinds of crops. The main limiting factors are rooting condition /loose sand accumulation of tsunami material. PMU 2, 3, 4, and 5 (complex of recent beach ridge and swale in marine region) are marginally suitable (S3) for cocoa, coconut and coffee, rambutan duku, durian, citrus, manggo, peanut, long bean, sweet potato, cassava and maize. The major limiting factors are low nutrient availability and rooting condition (sandy texture of sub-soil), and brackish water. PMU 6 and 8 (complex of beach ridges and swalle-resent with poor drainage) both units are not suitable for tree crops, however moderately suitable for wetland rice. The limiting factors are water inundation, low nutrient content and sandy texture sub soil. PMU 9 and 10 (complex of sub recent beach ridge and swale in marine region) are moderately suitable for coconut, rubber, papaya, banana, oil palm, rambutan, and citrus, manggo, manggoesten, water melon, nilam, shallot, red chili, maize, peanut, mustard, egg plant, sweet potato and cassava. The main limiting factors are low nutrient content and sandy texture sub soil. PMU 7 and 14 (sub recent of beach ridges and swalles covered by shallow peat), both units are marginally suitable for rubber, oil palm, coconut, rambutan, manggoesten, papaya, banana, peniaple and paddy. The limiting factors are water inundation, low nutrient and sandy material of sub soil. PMU 13 (beach ridges sub recent) is moderately to marginally suitable for Cacao, coconut, coffee, duku, durian, mango, manggosten, rambutan, banana, shallot, red chilli, mungbean, long bean, sweet potato and cassava. The limiting factors are low nutrient, sandy material of sub-soil, and water availability. PMU 15 (shallow peat: 0,5 – 1,0 m) this unit is marginally suitable for rubber, oil palm, coconut, banana, pineaple, egg plant, water melon, long bean. The limiting factors are water inundation, low nutrient content and the peat susceptibility to subsidence and oxidation. PMU 16, 17 (moderately shallow to moderately deep peat, peat depth 1,0 to

The limiting factors are water inundation and low nutrient content MU 18 (deep peat with peat depth >3 meters, peat depth localized areas reach 6 to 9 meters). This unit is not suitable for agriculture, recommended for conservation due to it’s fragile ecosystem. PMU 19 (levee) both unit are moderately suitable for coconut, coffee, duku, durian, manggoesten, rambutan pineaple, mung bean, long bean, soy bean, peanut, mustard, sweet potato and cassava. The limiting factors are low nutrient and water inundation PMU 11, 12, 20, 21, 22 and 23 (swalle, river backswamp, narrow criver valley, alluvio-marine deposits dominated by aquepts and aquents soil are moderately suitable for paddy. The major limiting factors is low nutrient availability PMU 24 and 28 (alluvial plain and undulating tectonic plain), both unit are moderately to marginally suitable for rubber, oil palm and paddy. The major limiting factor is low nutrient availoability and drainage assessibility. PMU 25, 26 and 27 (undulating to rolling tectonic plain) are suitable for rubber, oil palm, cacao, clove, banana, coconut, duku, durian, papaya, banan. The limiting factors are low nutrient and erosion hazard. Landuse Recommendations Numerous potential land-use for certain crops are feasible and can be identified by land evaluation of each physiographic mapping unit. To interpret the combination of land suitability class, screening is necessary based on the priority of regional/district development (Rencana Tata Ruang Daerah) and existing landuse. In the screening for annual food crops and vegetable crops, only S1 and S2 classes are considered, but for the perennial tree crops, S3 or marginally suitable class is also included because of the higher priority of the current project on perennial tree crops suitability evaluation. The approach in screening of land suitability is given in Table 2. The land that is currently being utilized, especially for perennial tree crops/ estate crops and paddy field fields are left as such as long as they fall into suitable class. Those lands may be recommended for intensification for increasing their productivity. Land that currently are not optimally used or not being used such as shrub, conversion forest, or absentee agricultural land were recommended for extensification for other suitable commodities. Landuse recommendation for Aceh Barat district coastal areas post calamity is presented in Table 3 and Figure 1 (Agricultural Recommendation map for West Coast of Aceh Barat District).
