Satisfactory background investigation and/or fingerprint check required. Multiple factors which affect irrigated agriculture productivity were considered, and an 85% threshold was applied to identify irrigable land. Suitability classes are applied according to economic measures rather than simply on the basis of assessments of physical productivity. Content Guidelines 2. 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. This study was conducted in the Abbay basin of Ethiopia to evaluate land suitability for irrigation considering both surface and groundwater sources using the analytic hierarchy process. In general, around 80.3 . Use email button above to contact. In general, a physical measure of productivity will be appropriate in reconnaissance low intensity studies. The unrecognised urban farmers of Delhi are caught in conflict over land. avoiding anomalies in classification caused by variations in cost recovery policy and law and in the extent of farmers' liability for land development costs; iii. 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. The NIIB may be calculated as follows: Minus (B) Annual Equivalent Value of Common Costs; Minus (C) Annual Equivalent Value of Area-specific Land Development Costs. 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. However, to determine the feasibility and actual design of specific projects, it is required to refine the land suitability classification by assessing water availability for irrigation and the economic viability of water supply. In-depth study of these provides clues to the nature of soil, land slope, soil depth etc. In this, only one soil property (say clay per cent) is examined in a grid pattern. FAO, Aquastat: Ethiopia. pp. 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. Final selection of LUTs for the 'irrigable' land - Incorporate organic matter in the soil. Figure 2 Nomograph for correlating incremental net farm income, net incremental irrigation benefit and area-specific development cost (Rupiahs).

The methods used in the study broadly follow the framework of the Food and Agriculture Organization of the United Nations (FAO) for land suitability evaluation. The maps rate land suitability for each crop/irrigation type as outlined below. 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. 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. The land evaluation team must decide which of these measures of suitability is most appropriate for a given evaluation. Extra profit from land levelling for furrow irrigating the unimproved land: $280 minus $127 equals $153 per hectare. Land irrigability assessment by Kolay (2008) is briefly presented. The surveyor resumes walking down the slope to demarcate soil B from C, soil C from D and so on. Srinivasan, Raghaven (Texas A and M AgriLife Research) Description. We use cookies on our website to give you the most relevant experience by remembering your preferences and repeat visits. Due to the main limiting constraints of depth, slope, and sand dunes, there is currently a small area that is not suitable for irrigation. Excessive percolation losses put a paddy rice crop on this land under more water stress resulting in yield depression. The study estimated that a total land area of 49.8 million hectares is suitable for irrigation in the Nile Basin, of which about 7.5 million hectares is highly suitable. Evaluating land suitability from the available land and water resources potential for irrigation development is very important for planning sustainable use of limited land and water resources. Soil water may be too saline or alkaline to support optimum growth and development of different crops for economic yields. Mr. Kiran M.

It is from this net income that repayment obligations must be met including, if any, costs for area-specific land development performed by the farmer or by the project and assigned to the farmer for repayment. Class 1Suitable land with negligible limitations (dark green) Class 2Suitable land with minor limitations (mid green) Use of costs and benefits in determining land suitability class, 7.4 Thus, a likely land use pattern for the project area as a whole will emerge. Using graph paper, the vertical scales are positioned equidistant from each other. The soil should not suffer from erosion, so that fertile soils remain intact in heavy rains and winds. Crop production may be risky without appropriate subsurface drainage. Analytical cookies are used to understand how visitors interact with the website. Boundaries between soils of clay percentages are successively drawn up as has been illustrated in Fig 15.3: Thorough knowledge of the land characteristics is necessary to assess leveling and drainage requirements for alignment of irrigation channels and drains. ; In the context of economic analysis any expenditure must be justified, on the grounds that benefits exceed costs, and enable the resultant productivity of the land (after the expenditure) to remain above the cut-off value. 2019).But, most researcher applied the biophysical factors for land suitability (Hailu and Shoeb . The farm land is in an area suitable for investment with gaining value every year. This residential plot has an on-sale . Use of this Web site signifies your agreement to the terms and conditions. The surveyor walks down the slope to observe soil surface features such as land slope, soil colour, texture and structure, erosion, vegetation etc. Sources of data. In making analyses at the farm level to choose the composition of enterprises or to test the feasibility of different kinds or levels of inputs or outputs, a shortened form of budget need only deal with the pertinent changes. They are 45 to 90 cm deep, loamy sand or clayey in texture. The Harmonized World Soil Database v1.2 (HWSD) and the Africa Soil Grids (AfSoilGrids250m) datasets were used to assess soil suitability. POWER SUPPLY: Other uncategorized cookies are those that are being analyzed and have not been classified into a category as yet. It will be noted that within any land suitability class, more than one LUT may be represented. Land suitability assessment for irrigation is critical to inform as well as manage current and future irrigated agriculture production systems. 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. Capability Vs Suitability Capability:- Capability is viewed by some as the inherent capacity of land to perform at a given level for a general use. For example, if the cut-off value were, say, Rp 250 000 per hectare and the best land would produce incremental benefits of Rp 323 000, the NIIB range for suitable land would be Rp 1 to 73 000 (annual), if the land in question had no area-specific land development costs. 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. pp. Land suitability Surface irrigation Weighted overlay ArcGIS Pair-wise comparison. shortened form of budgeting) could consist of a reduction of the land productivity index from, say 100% (i.e. A few full-farm budgets representing the modal tendency can serve as a basis for related partial budgets which subsequently examine the effects of variations such as technology and management levels, size of farm, levels of outputs and inputs, different crop yield assumptions, water supply variations, etc., depending on the level of detail needed.

Although these sites have good groundwater recharge structure, they are often limited. There should be focused resources allocation on project mode . 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. L. You et al., What is the irrigation potential for Africa? G. G. Haile, Irrigation in Ethiopia, a review, J. Environ. The comparison of the different types of irrigation revealed that sprinkler irrigation was more effective and efficient than the drip and surface irrigation methods and improved land suitability for irrigation . Lighter shades indicate past erosion and soil texture. Other similar supporting data could include schedules of the monthly and seasonal pattern of labour requirements, agrochemical usage and costs, etc. Such information aids in accurate determination of mapping units in the proposed irrigation soil survey on aerial photographs. Energy use before and after farms, as well as . If the land development costs exceed the calculated amount for the class, the land should be downgraded. References in the bibliography (Brown 1982; Gittinger 1982; Yang 1965) provide guidance on preparing farm budgets and enterprise analyses for crops or livestock production. Suitability classes are applied according to economic measures rather than simply on the basis of assessments of physical productivity. 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/. Irrigation Soil Survey: Irrigation soil survey is undertaken at a scale of 1:25,000 or 1:20,000 in less developed countries. The NIIB scale at the centre is half the length of the two outside scales. By delineating watershed boundary, irrigation suitability factors such as soil type, slope, land cover/use, and distance from the water supply were classified based on the FAO . April, pp. A combined biophysical and socioeconomic approach, Food Policy, vol. Irrigation soil survey is undertaken at a scale of 1:25,000 or 1:20,000 in less developed countries.

Soil salinity may be moderate when the soil water is in equilibrium with irrigation water. Factors influencing cost: benefit ratio. Table 23 illustrates how the cut-off value might be calculated for a hypothetical project. Furthermore, the land suitability classes obtained using these three measures may differ, as explained in Section 2.4, for any given land unit or LUT combination. ii. The country is endowed with ample water resources with 12 river basins. 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. The suitable land for irrigation from surface water was compared with small- to large-scale existing irrigation projects command areas for irrigation diversion in the basin. When he observes a change in any one of the features, he follows the line of change. January. Note that the broken line on the nomograph intersects the NIIB scale at Rp 5 000 corresponding to a land suitability class of S3. Appendix 2 shows how the discounting is performed. 15, p. 38, 2016. The annual equivalent value of this investment is Rp 25 000 at an interest rate of 12% over 50 years. Examples of the calculation of cut-off values, permissible development costs and NIIB, and of the translation of NIIB into land suitability classes are given below. Their lower subsoil is moderately permeable or they possess 15 cm thick permeable layer of sand, gravel etc. These cookies ensure basic functionalities and security features of the website, anonymously. The objective of this study was to evaluate the suitability of the soil properties of the area for irrigation purpose. Table 18 illustrates how three optional choices can be tested in terms of farm income. This chapter explains, with reference to examples, how economic considerations are introduced into the selection of LUTs and land suitability classes. The permissible area 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. The area of planned irrigation schemes under each land suitability category is also provided. Permeability of the subsoil and feasibility for installing drainage system, 6. They are temporarily considered to be non-irrigable due to severe limitations for sustained utilisation under irrigated conditions. Values used for the nomograph are generated by determining the cut-off value, the net farm income values in farm budgets, and the range of permissible area-specific land development costs. for comparisons of returns, 7.3 International work experience in preparation of Land Use Plans, implementation of irrigation systems or similar interventions in arid regions preferably of Eastern Africa/HoA ; . They may be slightly alkaline with an ESP of 10 to 15. Use of costs and benefits in determining land suitability class, 7.3.1 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. The land suitability parameters such as soil properties, slope, land use and land cover were used to identify the suitable irrigable land. The soil suitability index was combined with the terrain suitability categories to generate the final suitability map. Then he digs the soil profile in each of the soil units A, B, C . This study applied a GIS-based Multi-Criteria Evaluation (MCE) technique to evaluate the suitability of land for irrigation in Ghana for a baseline period (1990 to 2010) and future time horizons . Numerical 1, 2, 3, 4 and 5 denote land irrigability classes which are used for these appraisals relating them. These soils are not suitable for irrigated agriculture. The irrigation land suitability of each physical land parameter was classified into four suitability classes (S1, S2, S3, and N) based on the Food and Agricultural Organization guideline . Table 19 FULL FARM BUDGET FOR LUT A (1.0) ON THE BEST LAND 1/PADDY RICE FARM - 2.0 HECTARES WITH AND WITHOUT SUPPLEMENTAL IRRIGATION - Indonesia. As explained in Chapter 1, land suitability evaluation is essentially an economic concept. One combination of surface features and soil characteristics continue up to certain distance when the soil surveyor continues to examine the soil in grid pattern. Each position will be for three years. However, there is a practical limit to the number of plans that can be analysed when deadlines must be met. In Ben Tre province, shallow groundwater found at a depth of 8 to 60 m is exploited for domestic use and for irrigation of crops in rural areas. To set the boundaries of 'Suitable' classes (i.e. Saline patches may cover 15 to 20 per cent of their surface. 129. pp. Agric., vol.

It follows from this that if (A) minus (C) is less than (B), the land in question is 'Not Suitable' for irrigation development and can be classified as N1 or N2. Table 22 is a partial budget that shows the changes in variable costs and returns for such a situation, and derives the net farm income. The 150 acres of land at the center has diverse soil types and utilizes Artesian water rights making it suitable for growing a variety of perennial and annual crops. 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. Land that cannot generate a net incremental value of production equivalent to or greater than the cut-off value would normally be classified as 'Not Suitable'. M. Bousquet, K. Frenken, L. Verelst, and W. D. Division, Assessment of irrigation potential in Africa. pp. The present conditions have the following disadvantages which are evaluated in terms of yield depression, inefficient irrigation application, higher labour requirements, loss of fertilizer due to uneven water distribution, and higher costs for some field work. Soils have been divided into A, B, C and D irrigability classes, with conditions deteriorating from A to E. These soils have no limitations for sustained crop production. Land suitability was evaluated by assessing the soil and terrain suitability for irrigation. Potential crop yields and cost of production, 7. Encourage best practice in the management of land and water. Adequate precautions are to be taken to develop land for different methods of irrigation without causing erosion or waterlogging. This land has a selling price of Rs 20.6 Lac and spreads across an area of 1500.0 square feet with dimensions of 50 X 30. October. Five land suitability classes are defined for use in Queensland, with land suitability decreasing progressively from class 1 to class 5. Land suitability is the fitness of a given type of land for a defined use. In some cases (e.g. Detailed soil survey may be free survey or grid survey. Price update on 11.01.2023, 13.10. 2/ Soil deficiency evaluated as having the same effect on crop production without and with the project. Agriculture is extremely vulnerable to climate change, creating more difficult challenges. The application of any formal economic analysis is, of course, seldom possible in the earlier stages of a land evaluation exercise when only rough estimates of development costs and of potential levels of productivity are usually available. 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). Table 27 FARM BUDGETS ESTABLISHING NIIB RANGE FOR IRRIGABLE LAND (ECONOMIC ANALYSIS) - 15 hectare farm, Less: Annual equivalent of common project investment, Annual operation, maintenance and replacement, Net Incremental Irrigation Benefit (NIIB) 6/.
