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 order to attribute net values to the production of each LUT, it is necessary to prepare full or partial crop or farm budgets. Agriculture is a mainstay of Ethiopian economy. Y. Chen, J. Yu, and S. Khan, Spatial sensitivity analysis of multi-criteria weights in GIS-based land suitability evaluation, Environmental Modelling and Software, vol. The latter are area-specific costs and are land class-determining. It does not store any personal data. Economic It provides baseline information for further more complex analysis of water and environmental suitability for irrigation development. The construction of a nomograph is quite simple. They are used to assess drainage conditions; g, u and f denote slope, undulation and flooding respectively; s, t ad d denotes soil, topography and drainage deficiencies respectively. Final selection of LUTs for the 'irrigable' land Before uploading and sharing your knowledge on this site, please read the following pages: 1.

The Sustainable Irrigation Program undertakes a range of actions to improve on-farm water use. A number activities are used to support improved irrigation water use efficiency, including: Property planning (including grants for the preparation or update of whole farm plans), and other decision support programs. October. Such may not be the case where the land use is to be changed appreciably by the project. production. 4, no. Land suitability assessment for irrigation is critical to inform as well as manage current and future irrigated agriculture production systems. As explained in Chapter 1, land suitability evaluation is essentially an economic concept. For any one land unit or grouping, one or more alternative LUTs may be recommended. These are excessively limited for normal crop production. for land clearing, drainage, levelling, etc.). within 3.0 m from their ground surface. The Annual Equivalent Value of Common Costs (B) thus represents the cut-off value for required net incremental farm income (after payment of area-specific development costs). 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. Note that the broken line on the nomograph intersects the NIIB scale at Rp 5 000 corresponding to a land suitability class of S3. 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. 117126, 2012. 114, 2006. Abraham Mahari, Azalu Alebachew, Debre Markos. Budgets are generally needed to represent: The first two of these budgets for the 'without' project situation are usually alike except when trends are judged likely to make the future setting different from the present. Less than 60 m of shallow drains are enough to drain away excess water. There should be focused resources allocation on project mode . Multiple factors which affect irrigated agriculture productivity were considered, and an 85% threshold was applied to identify irrigable land. For example, in irrigation water at Carnarvon, only about half . Detailed soil survey is necessary to assess their degree of suitability for irrigation and to know what precautions should be taken for an ideal irrigation system. 7989, 2004. Land with lower productivity would bear proportionately lower investment costs. Copyright 10. These lands are not suitable for sustained use under irrigation. ii. 5, no. January. All suitable land is shown in green. Letters X, Y and Z denote good, restricted and poor drainage conditions. Their effective depth exceeds 90 cm and texture varies from sandy loam to clay loam. Rock out crops may occur at an interval of 20 m apart. The cookie is used to store the user consent for the cookies in the category "Analytics". Presently, the agricultural sector contributes to between 19 and 29% of all global greenhouse Gas (GHG) emissions. Sources of data. 1423, 2013. Excessive percolation losses put a paddy rice crop on this land under more water stress resulting in yield depression. Agric., vol. These soils are suitable but approaching marginality for sustained crop production under irrigation. Table 25 PERMISSIBLE AREA-SPECIFIC LAND DEVELOPMENT COSTS, Permissible development costs (annual equivalent) Rp, Actual development costs, annual equivalent cost, say, Rp, NIIB (net incremental irrigation benefit) Rp. They are non-saline with EC less than 4 micro mhos cm-1 at 25C and that of 1:2 soil: water suspension of less than 1 micro mhos cm-1 at 25C and non-alkaline as indicated by ESP of less than 10. The economic consequences of changes in physical productivity and costs of production will demarcate a boundary or cut-off point between land which is suitable for irrigation and land which is not. It is often desirable to examine more than one overall land use pattern for the project area. Box: 27173-1000 Lamberet, Dessie Road,Addis Ababa, Ethiopia. Factors influencing cost: benefit ratio. Satisfactory background investigation and/or fingerprint check required. Lighter shades indicate past erosion and soil texture. Economic comparisons will assist the selection of 'class-determining' requirements and limitations for each LUT. For Sale: Condominium home, $349,000, 2 Bd, 2 Ba, 1,128 Sqft, $309/Sqft, at 466 Bouchelle Dr #202, New Smyrna Beach, FL 32169 Their suitability to irrigated crop production depends on effective soil depth, surface soil texture, permeability, water retentive capacity, severity of salinity or alkalinity, drainage characterstics etc. Table 28 FARM BUDGETS ESTABLISHING FARMER'S FINANCIAL VIABILITY UNDER IRRIGATION (FINANCIAL ANALYSIS) - 15 hectare farm, Less annual project operation and maintenance cost, Less annual charges for water (towards repayments). This residential plot can be utilized once you pay the booking amount of Rs 100000. Storage is accommodated with a 4-bay shed and irrigation equipment is included . . for comparisons of returns, 7.3 Elsevier B. V., pp. Long, efficient north running rows and fully irrigated, the farm also boast a great homestead, sheds and water allocation. Water holding capacity varies from 9, 0 to 12, 0 cm per 90 cm depth. Published 2013. 7.2 Budgeting Available moisture retentive capacity is at least 12 cm per 90 cm soil depth. The outputs could be suitable for basin-level land suitability assessments, and for the identification of potential regions for further exploration of water availability and subsequent irrigation development. The NFU pledges to: Promote the implementation of contingency planning on farms to tackle the dual risks of flooding and water supply disruption. They are temporarily considered to be non-irrigable due to severe limitations for sustained utilisation under irrigated conditions. Land Suitability Evaluation for Irrigation in Dejen District, Ethiopia. Blue ribbon farming at its best in the Isis region. No other permeable layer of at least 15 cm thickness occurs within 3.0 m from ground surface. This approach contrasts with that adopted by the USBR which classifies land according to its 'payment capacity'; this is essentially a measurement of financial impact of irrigation development on the income of the typical farmer (see Chapter 10). On many rainfed areas, the future situation without the project can be represented by a single budget (or a limited few) if the present situation is fairly uniform and stable throughout. The country is endowed with ample water resources with 12 river basins. FAO, Guidelines for Intergrated Planning for Sustainable Management of Land Resources. p. 88, 1999. The land use map has eight types which includes wetland, water body, urban, shrubs, grassland, forest, bare land and agricultural land. Soil suitability was assessed using parameters such as drainage, texture, available water storage capacity, pH, physico-chemical organic carbon, salinity, sodicity and soil depth. the value obtained by subtracting both the variable and fixed costs from the gross value of production on a given unit of land (Section 2.4); - Net Incremental Irrigation Benefit (NIIB), a measure of the potential increase in productivity of a unit area of land when developed under a specified plan, expressed in economic terms as an Annual Equivalent Value (see later in this Chapter). Support to the restructuring of irrigation and drainage institutions of the Government of Ghana; and; Support for the development of Water Users' Associations and new scheme management institutions. 117136, 2003. 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. Assessing the Suitability of Water for Irrigation ; Assessing Soil Salinity ; Soil Salinity Patterns and Irrigation. Other considerations might apply where it would be desirable to specify ranges of land use, as appropriate, for the envisaged degree of control over land use. in a classification of 'irrigable' land. No other permeable layer of at least 15 cm thick occurs within 3.0 m from ground surface. The overall intention of the assessment was to identify soil and land resources in the Darwin region suitable for a potential new irrigated horticultural precinct. Each position will be for three years. (email: brhanson@ucdavis.edu) or Stephen Grattan (email: srgrattan@ucdavis.edu), Department of Land, Air and Water Resources, University of California, Davis, CA 95616-8628; telephone .

Farm budget calculations are carried out using production or relative yield levels corresponding to the economic cut-off boundary between 'Suitable' and 'Not Suitable'; and also using ceiling values for the most productive land. 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. 118128, 2013. Permeability of sandy soils and clayey soils varies from 130 to 250 cm h-1 and from 0.3 to 1.3 mm h-1 respectively. MoA, Small-Scale Irrigation Situation Analysis and Capacity Needs Assessment:, Natural Resources Management Directorate, no. In general, a physical measure of productivity will be appropriate in reconnaissance low intensity studies. The poorest land to be classed as 'Suitable' must be able to carry its share of the common project costs, otherwise it should be classified as 'Not Suitable'. After consultation among appropriate personnel, a likely pattern of land use should evolve which meets the project objectives and the approval of the authorities, and produces sufficient benefits to justify the project in economic terms. S. B. Awulachew and M. Ayana, Performance OF irrigation: An assessment at different scales in ethiopia, Exp. evaluation of land suitability for irrigation, 7.2 Budgeting Result of suitability of land evaluation ratings based on the qualitative land suitability for irrigation indicated that, 9.32% (1303 ha) are highly suitable (S1), 32.5% (4558 ha) are moderately suitable (S2), 23.82% (3335 ha) marginally suitable (S3) and 34.30 (4802 Main water supply 8-12-meter (25-40 feet) pressure will delivery a standard two- storey building, although taller buildings will include pressure booster systems. Land suitability analysis determines whether a given land area could potentially be used for specific crop production. - Destroy weeds. 2. pp. 7.3.3 Nomograph 3. pp. Soils may be slightly saline as indicated by EC of saturation extract of 4 to 8 micro mhos cm-1 at 25C and that of 1:2 soil: water suspension of 1.5 micro mhos cm1 at 25C. Crop production may be risky without appropriate subsurface drainage. Budgets representing the future situation 'with' the project will be required for whatever number of LUTs it is desired to examine for a land unit. International work experience in preparation of Land Use Plans, implementation of irrigation systems or similar interventions in arid regions preferably of Eastern Africa/HoA ; . Agriculture is extremely vulnerable to climate change, creating more difficult challenges. 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 based on GIS and remote sensing approaches.
