Water supplied by GMW is not suitable for human consumption without first being properly treated. Variable Costs (from schedule C, see Table 20 for details): 1/ Land Productivity Index Level (1.0) represents the best quality land. Saline patches may cover 15 to 20 per cent of their surface. They may be very strongly saline/alkaline as indicated by their EC more than 16 micro mhos cm-1 at 25C, that of 1:2 soil: water suspension of more than 3.0 micro mhos cm-1 at 25C and ESP exceeding 30. Depth of water table is more than 5 m. Subsurface drainage is not required. This indicates that the soil mapping unit B has ceased to occur and the soil mapping unit C has begun to occur and so on. The classification of 'irrigable' land is more precise and should generally result in a determination of the number of hectares, by land suitability classes and subclasses, comprising a recommended irrigation service area under a project plan. Economic Land Suitability Evaluation for Irrigation in Dejen District, Ethiopia. Cogent, 2018. however, land with factor ratings of s1 and s2 would tolerate this cost but their final classifications might be downgraded to S2 and S3 because of such costs. Budgets are usually prepared in detail to show the net income for a farm, a unit of area, or an enterprise. The weighting analysis of all parameters resulted that 34.08% was classified as high suitable (S1), 58.08% moderately suitable (S2), 3.8% marginally suitable (S3), whereas 3.21% not suitable (N) for surface irrigation development. The draft Delhi Master Plan 2041 charts out a green belt and . Geography. Report a Violation 11. Such may not be the case where the land use is to be changed appreciably by the project. They are shallow soils with depth varying from7.5 to 22.5 cm and of texture sand or clayey having available water holding capacity varying from 2.0 to 6.0 cm per 90 cm soil depth. Irrigation of sugarcane has already been implemented in main sugarcane areas.Suitable water condition and reasonable nutrient supply are the basic guarantee of high yield and quality of sugarcane.Water stress, nutrient dificiency and the asynchrony of the two are bad for the growth of sugarcane[2].Moisture factor is an important factor influencing the elongation of sugarcane stalks.Many .

The objective of this study was to identify the availability of suitable land for surface irrigation systems for the production of . They are 45 to 90 cm deep, loamy sand or clayey in texture. Disclaimer 8. Two options for investment in irrigation improvements on the farm are compared with the option of no improvements. Detailed soil survey commences from a permanent object such as bench mark, building etc. Available moisture retentive capacity is at least 12 cm per 90 cm soil depth. R. G. Allen, L. S. Pereira, D. Raes, and M. Smith, Determination of ET. Suitable soil conditions for irrigation may be summarised as follows: The soil should be moisture-retentive type so that it may feed the crop for a considerable time. and Suitability:- Suitability as a statement of the adaptability of a given area for a specific kind of land use; others see capability as a classification of land primarily in relation to degradation hazards (FAO, 1976). 2/ Soil deficiency evaluated as having the same effect on crop production without and with the project. FAO, Aquastat: Ethiopia. pp. The 2 main types of systems are: primary simple systems which are comprised of only septic tank/s with no secondary treatment for sub-surface disposal only. An unfavourable outcome might result from any of the following: b. the assumptions used in farm budgets may be incorrect, unrealistic, or both; this could apply to economic and financial budgets, or both; c. financial prices or other factors subject to official intervention may be inappropriate; d. inequities may prevail, for example, due to institutional factors such as tenure, farm size, rents, taxes, etc. Land suitability assessment for irrigation is a very important tool not only in terms of agriculture development planning, but also to overcome the global problem of water scarcity. Pecan production is expanding the Southeastern part of New Mexico and there are currently 5 acres of Western Schley and 5 acres of Pawnee pecan trees to support pecan research at the center.New Suitability classes are applied according to economic measures rather than simply on the basis of assessments of physical productivity. 117126, 2012. They may be moderately alkaline as indicated by their ESP of 15 to 20. 3. The application of any formal economic analysis is, of course, seldom possible in the earlier stages of a land . Table 23 CALCULATION OF AN ECONOMIC CUT-OFF VALUE - 2 500 hectare irrigation project - Indonesia, Annual equivalent cost (at 12% over 50 years), Cut-off value, per hectare (or required net incremental farm income after attribution of area-specific development costs). In grid survey, soil observations are noted down in a grid pattern at short regular intervals. Irrigation in Ethiopia is considered as a basic strategy to alleviate poverty and hence to achieve food security . The rating of soil and landscape characteristics for a given land area will assist in making an initial assessment of land suitability for irrigated potato production. for land clearing, drainage, levelling, etc.). ii. Figure 2 Nomograph for correlating incremental net farm income, net incremental irrigation benefit and area-specific development cost (Rupiahs). Using a geographic information system, the researchers determined the physical irrigation suitability of the Sibilu River watershed. between S1, S2 and S3), the range of NIIB between the cut-off point (NIIB = 0) and the maximum obtainable in a project area may be divided into three equal or unequal segments. 7. The soil suitability index was combined with the terrain suitability categories to generate the final suitability map. suitable for permanent plantings, 3 Ag Wells, borders bypass . To begin the process of eliminating less promising LUTs, array the LUTs by land productivity index, net farm income, or NIIB, depending on which indicator is appropriate for the stage of the evaluation.

Live the dream and continue the cashflow with the productive irrigated land that is subdivided into 11 well fenced paddocks with a very good set of cattle yards. 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. Agriculture is a mainstay of Ethiopian economy. If the land development costs exceed the calculated amount for the class, the land should be downgraded. If the project plan is to be sustained, it must also be financially remunerative to individual farmers. Table 26 SUMMARY OF IRRIGABLE LAND CLASSES AND PROJECT AREA HYPOTHETICAL PROJECT - INDONESIA (Net Farm Income Rp/ha x 1 000), Class S2Land units: 1, 3, 4, 6, 8, 14, 19, 20, 21, 22. 192 ACRE OF RED SOIL CULTIVATION & WATER. Basins are to be made for fruit trees. 4, no. Table 27 illustrates a case in which the values for the cut-off and the range of permissible development costs are determined using economic criteria pertinent to the project (as described in Section 7.3). It is often desirable to examine more than one overall land use pattern for the project area. The critical objective of this study was to evaluate the suitable land resource potential for irrigation development for the Katar River watershed in the Rift Valley Basin in Ethiopia by using ArcGIS based on Multi-Criteria Evaluation (MCE) techniques. 109. The cut-off value is calculated by dividing the investment in common project facilities by the number of hectares in the project, converting to an annual equivalent cost, and adding the project's annual operation and maintenance costs (replacement costs are most readily represented as an annual equivalent in the operation and maintenance costs, OM & R).
