All suitable land is shown in green. If the project plan is to be sustained, it must also be financially remunerative to individual farmers. (a)Is a situation in which least possible cultivation operations are carried out in crop. The conversion of investment values to annual equivalent costs (and any other discounting processes required) will utilize the investment rate of interest or opportunity costs of capital specified by the project sponsor. The results demonstrated that by applying sprinkler irrigation instead of surface and drip irrigation methods, the arability of 12 590 ha (94.7%) in the Gotvand Plain would improve. This study was initiated with the objective of analyzing land suitability for surface irrigation in Humbo woreda, Southern Ethiopia. Such initial calculations may also help identify alternative LUTs, including possible cropping, irrigation and management systems, and the approximate amount which can be invested in land development. 1. Permeability of the subsoil and feasibility for installing drainage system, 6. Finally, comparing the required gross irrigation water requirement and available monthly flow of the River, the River has the capacity for the fulfilling irrigation water demand to irrigate command area of the watershed during dry season. The Openn Offers is under way and the property can sell at any time. For example, in the case where the per hectare ranges for 'Suitable' are established as follows: the permissible area-specific land development costs for any given land suitability class can be calculated, using the value at the bottom of each class as a cut-off, as illustrated in Table 25. GCAP is looking for suitable candidates for a number of key positions as specified in detail below. Land Suitability, Irrigation Potential, Slope Suitability, Water Availability, ArcGIS, Katar Watershed, http://creativecommons.org/licenses/by/4.0/.
