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. Table 18 illustrates how three optional choices can be tested in terms of farm income. The FAO methodology employs financial analyses, using farm budgets, as explained later in this chapter, to confirm that, under current or expected market conditions, there are financial incentives for farmers to participate in a proposed irrigation development programme on a particular land area. A multi-criteria evaluation (MCE) procedure following Analytic Hierarchy Process (AHP) method was used on a geographic information system (GIS) platform to develop a composite soil suitability index. 47, no. Class 1 land is highly productive, requiring only simple management practices to maintain economic production, with minimal degradation to the land . And then, re-classification and mapping according to suitability classification, identification of irrigable land, and estimation of surface water potential and irrigation water requirements were followed. For example, in irrigation water at Carnarvon, only about half . Budgets are usually prepared in detail to show the net income for a farm, a unit of area, or an enterprise. The interest rate is 8% p.a. 7.2 Budgeting 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 . For the sake of illustration, assume that the crop yield is depressed because of a coarser textured soil and excessive permeability. Some of the feasible solutions such as intensification of cultivation with double cropping in suitable environment, proper nutrients, water, pest and post-harvest management practices must be pursued on war footings. Group I Soils with no serious disabilities for irrigation except, in some cases, situation above gravity supply level. Improving irrigation facilities is considered as a key strategy to enhance agricultural productivity. Corner of Ave 18 and . 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. Using graph paper, the vertical scales are positioned equidistant from each other. 2007. - Incorporate organic matter in the soil. These are of little inferior quality than class A soils because they are moderately limited to be permanently irrigated for crops on sustained basis. Copyright 10. for market needs, to even out labour peaks, to improve seasonal cash flow, or to lessen overdependence on a given crop, etc. 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. 1.
