Alternatives must be resolved into specific cropping, irrigation and management systems proposals that are realistic, practicable and likely to occur. The farm has 7 boreholes, 6 sun pumps and +/- 20 -x 5000 L water tanks, 1 x earth dam and water is piped to a 200 000 L Sink dam/ reservoir which again feeds tanks for domestic use, irrigation and livestock watering purposes. Table 23 illustrates how the cut-off value might be calculated for a hypothetical project. Factors such as water supply, climate, agronomic practices, or economics that influence the decisions of whether land . Results of the land suitability evaluation for surface irrigation showed that, a total area of 3064 ha (72.6%) was slightly suitable (S3) and area of 1154 ha (27.4%) was currently not suitable (N1). If the figure Rp 73 000 (Table 24) is the NIIB for LUT A (1.0) (from Tables 19-21) for land classified as S1 in an 'irrigable' classification and if the NIIB is capitalized (12%, 50 years), an investment limit of Rp 606 200 for an area-specific land development cost applies on the best land in the project. Water Land Dev. Available moisture retentive capacity is at least 12 cm per 90 cm soil depth. Each land unit-LUT combination is finalized (i.e. 15, p. 38, 2016. S. B. Awulachew and M.

Saline patches may cover 15 to 20 per cent of their surface. The area of planned irrigation schemes under each land suitability category is also provided. Permeability of sandy loam soils varies from 5.0 to 60.0 mm h-1 and that clay loam from 5.0 mm h-1. These lands are not suitable for sustained use under irrigation. Land irrigability classification is based on the: 4. Content Guidelines 2. Interest and Discounting Calculations. (The assumptions about water charges will, of course, vary widely from project to project.). Adequate precautions are to be taken to develop land for different methods of irrigation without causing erosion or waterlogging.

Evaluation of Land Suitability for Irrigation Development and Sustainable Land Management Using ArcGIS on Katar Watershed in Rift Valley Basin, Ethiopia, Journal of Water Resources and Ocean Science. This land can be farmed under irrigation in the natural condition in spite of the undulating topography. The aim of this study is to spatially evaluate land suitability of the study area, Kilte Awulaelo district in Ethiopia, for surface and drip irrigation methods . These soil units are provincially designated as the soil series possessing specific combination of surface features and profile characteristics. FAO, Irrigation in Figures - AQUASTAT Survey 2005. pp. Establishing the range of permissible area-specific land development costs, 7.3.3 Nomograph
These are excessively limited for normal crop production. Improving irrigation facilities is considered as a key strategy to enhance agricultural productivity. Land irrigability classification needs informative appraisals by an integrated analysis involving economic, hydrological, engineering, land and soil characteristics. production. This chapter explains, with reference to examples, how economic considerations are introduced into the selection of LUTs and land suitability classes. 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). Numerical 1, 2, 3, 4 and 5 denote land irrigability classes which are used for these appraisals relating them. If the financial residual, after water and operation and maintenance charges are paid out, remains more than the cost of area-specific development costs to be borne by the farmer, the farm's financial viability at the cut-off point is confirmed. Highly suitable for sustained irrigated agriculture. This is not to imply, however, that economic considerations should be disregarded at the outset of studies, when even 'back-of-the-envelope' calculations may help in distinguishing between land which is provisionally 'irrigable' and that which is not. Report a Violation 11. References in the bibliography (Brown 1982; Gittinger 1982; Yang 1965) provide guidance on preparing farm budgets and enterprise analyses for crops or livestock production. The result of land suitability of study area for the development of surface irrigation system (Table 6), indicated that 9.32% (1303 ha) are highly suitable, 32.5% (4558 ha) are moderately suitable, 23.82 %( 3335 ha) marginally suitable and 34.30 (4802 ha) are not suitable for surface irrigation systems. 5, no. 8, no. 5769, 2011. Such information aids in accurate determination of mapping units in the proposed irrigation soil survey on aerial photographs. ii.

Three alternative measures of land suitability class have already been defined in Chapter 2, namely: - Net Farm Income, i.e. 129. pp. A good friable topsoil of sandy loam, loam or sandy clay loam, of 35 to 40cm depth with an abundance of organic matter (2% organic carbon) in the first 20cm. 7.3
Suitability classes are applied according to economic measures rather than simply on the basis of assessments of physical productivity. When he finishes the soil examination, he draws the boundary between soils mapping units A, B, C (Fig 15.2). Extra profit from land levelling for furrow irrigating the unimproved land: $280 minus $127 equals $153 per hectare. 109. Because a major concern for most countries which embark on the development or rehabilitation of irrigation systems is the impact that the required investments will have on the economy as a whole, it is appropriate to apply economic rather than financial methods of analysis in the final classification of land suitability for irrigation 1/. If the project plan is to be sustained, it must also be financially remunerative to individual farmers. Rock out crops may occur at less than 5 m apart. W. Negash, Gis Based Irrigation Suitability Analysis (a Case Study of Abaya-Chamo Basin, Southern Rift Valley of Ethiopia), Lake Abaya Research Symposium 2004 - Proceedings, no. The land is suitable for many applications whether you are a retiring farmer or a first time lifestyler. 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). 1.

Agriculture is extremely vulnerable to climate change, creating more difficult challenges. The use of a nomograph simplifies the attribution of classes (see Subsection 7.3.3 and Figure 2). The procedure described enables a determination of irrigation benefits, but avoids dictating the precise land use pattern to the farmer. There is no necessity for subsurface drainage. The key factors considered evaluating the suitability of land for irrigation include biophysical features (such as climate, land use and land cover, soil proximity to the river, and slope) and socioeconomic factor (such as proximity to road and population density) (Worqlul et al. 15, no. 264269, 2015. In general, a physical measure of productivity will be appropriate in reconnaissance low intensity studies. increased investment costs charged to the farmer must be covered; iii.
