land suitability for irrigation

. Hence an appropriate drainage provision should be taken into consideration in further development.

The limiting factors were soil texture, slop and drainage. The importance of land evaluation points to opportunities for influencing future developments of land resources in the region using management techniques that are tailored to the characteristics of the landscape elements. In the application of the AHP method it is important that the weights derived from a pairwise comparison matrix are consistent. % Estimation of potential yield for each agroecological zone or land suitability class is another important problem, which is ignored in the above-mentioned studies. Van Zanten etal. Steps used in the AHP method to establish weights as a flow chart [19]. In order to implement the methodology, FAO principles and guidelines should be conformed to the specific area characteristics and to OMW composition, as well as to regional action plans. Characterizing slope of an area is important, which directly controls the balance between runoff response and soil infiltration rates of topography. It is necessary to determine spatially and quantitatively the potential to expand arable land without jeopardizing food and feed production. WebThe term land suitability for agriculture is defined as the lands ability to reach potential yields in a number of crops. For comparative purposes base saturation was expressed as the S value (sum of extractable bases) per unit clay, in that publication as me/100g clay, and not per unit soil. 0000022581 00000 n Lawn size will also be a factor in assessing costs for the installation of irrigation systems. Factors to consider. The diagonal of the matrix contains only values of 1.

Churi etal. [18] Figures 3-5. WebIrrigation suitability land classification investigations are an integral part of multi objective planning for the development and operation of water resource projects with an irrigation component. The evaluation procedure is an essential preliminary to project planning and should be conducted in a manner that will minimize costs, but at a level that is consistent with achieving practicable recommendations. By doing so, the different land classes including their yields are considered which is one of the major differences between the LUR and LCA studies. By combining better weather forecasting techniques to make better use of effective rainfall with, for example, VRI, the negative impacts of agroclimate uncertainty on crop yield and quality could be reduced.

Further details are given in FAO Soils Bulletin No. (2002) used GIS to analyze technology use and land use among Kenyan enterprises. (2016) developed a land use efficiency assessment method called Land Use Ratio (LUR) to deal with feed-food competition. LCA studies assess land use based on the total area needed to produce one unit of a commodity. The denominator is the HDP of one kg ASF. Van Hal, Weijenberg, De Boer, and Van Zanten (2019) therefore presented a novel allocation method that reflects the (un)suitability of feed products for human consumption. Proper use of land depends on the suitability or capability of land and water resources for the development of irrigation facilities could lead to substantial increase in food production [6].

In line with this, the profile pits were geo referenced using Global Positioning System (GPS). Legislative and other generally accepted restrictions for waste landspreading should be taken into consideration, too (MAFF,1989; Soil Science Society of America,1986; LIFE-AgroStrat,2016). The middlemen normally can manipulate farmers because they are well informed of the urban markets prices where the farmers' produce are expected to be transported for sale. Electric conductivity of saturation extract (ECe) was determine by 1:2.5 ratio of soil to water suspension using EC meter, and Percentage of calcium carbonate (% CaCO3) was measured using rapide manometric method meter [14]. World Bank Group (2012) reported about DrumNet system, which is used to bring together agricultural stakeholders and network. Last, assess the amount of HDP in one kg ASF, the denominator (Van Zanten etal., 2016). After categorizing the distance map of the river in to four different classes, the farthest distances were assigned as not suitable and closer distances was classified as highly suitable. Chapter 1 of Part One outlines the role of land evaluation in the development of land and water resources for reconnaissance surveys through to the detailed design of irrigation projects.

The suitability class of a land parcel concerning market access, road and river proximity is determined by its distance about the road network, a large town, and perennial rivers. As a result, percent of clay takes the highest proportion of the soils textural class followed by silt and sand.

Changes in water quality are not consistent throughout the subarea. (2015) developed three separate regression models based on saffron yield and monthly average, monthly minimum, and monthly maximum temperatures in selected districts over Khorasan Razavi province, Iran. Chapter 5 describes procedures for making a land resources inventory. To achieve this, characterization and geo-referencing the biophysical database is required, hence the following datasets were collected and reclassified in to different suitability classes. Distance to the existing river was calculated in ArcGIS tool by projecting the locations to a Mercator (UTM) Zone 37N. In addition, auger observations for soil depth and drainage measurement for soil drainage evaluation on each representative site were made. A = Rating of soil texture; B = Rating of soil depth; C = Rating of CaCO3 status; D = Rating of electro conductivity; E = Rating of soil drainage; F = Slope rating. 32.

On the other hand, the fine sandy soils are extremely vulnerable to subsurface soil compaction (development of traffic pans under intensive cultivation) and require special soil management systems, like rip-on-row and controlled in-field traffic (Laker and Nortj, 2020). Experimental Agriculture 47: 57-69. Information systems: Use of GIS has been well received and adopted in Africa like in other parts of the world. WebKey factors considered to evaluate the suitability of the land for irrigation include biophysical features (such as climate, land use, soil, and slope) and socioeconomic factors (such as proximity to roads and population density).

Accounting for feed-food competition with food-based allocation further reduced impacts per kg egg by 96 percent for LU to 0.11 m2, and by 88 percent for LUR to 0.30. Consequently, most of the area of the watershed come under gentle(51.5%) and flat(27%) slopes, and can be classified as good category for surface irrigation [20]. Abraham M, Daniel H, Abeba N, Tigabu D, Temesgen G, et al. (2016) found increased soil stability with increasing degree of weathering. Distinguishing of series on the basis of sand grade in sandy soils, usually those with 06% or 615% clay, is, from practical considerations, very important. Adapted FAO (1976) suitability classes, as cited in Van Gool etal.

ERX%Y>1][mIv|K The worksheet generates an annual x{qH To compute the LUR of one kg ASF from a specific livestock system, four steps are required. The process of land suitability classification is the appraisal and grouping of specific areas of land in terms of their suitability for defined uses [5]. Land having no significant limitations to sustained application for a given land use or only minor limitations. The chapter explains how to verify both the economic and financial viability of a project from the national and farmers' viewpoints. To evaluate the impact of accounting for feed-food competition on LCA results, Van Hal etal. While agroecological zoning and land suitability assessment are extensively used in different countries and for different crop species, application of these methods for saffron and other spices is overlooked and existing published reports suffer from lack of standard methodology. The authors confirm and declared that there is no conflict of interest in this paper. Clay soils hold water longer than loamy or sandy soils do, but it also takes longer for water to absorb. In general, we see that most current monogastric systems in the EU have an LUR >1 as their diets consist of large amounts of small grains, maize, and meals such as soybean meal or rapeseed meal and pulses. Abraham M, Azalu A (2013) Land Suitability Evaluation for Irrigation in Dejen District, Ethiopia. Farmers also face a range of nonclimate risks that potentially represent a more immediate threat to sustainable food production than climate change. The aim of this study was to evaluate the suitability of the land for surface irrigation using GIS based weighted overlay analysis of individual parameters for better utilization of land resources. WebThe main goal of these guidelines is to provide a methodology for implementing in irrigated agricultural systems the key principles of the Framework for Land Evaluation (FLE): (1) matching the requirements of the land use against the qualities of the land, (2) comparing alternative sustainable uses, and (3) multidisciplinary approach. The construction of a suitable model will have advantages as compared to traditional forecasting. Very high risk of negative economic, environmental, and/or social outcomes if not managed. GIS is used to assess irrigation systems (Fue and Sanga, 2015).

Aker (2011) reviewed several ICT-based systems, including radio-based, phone callbased and SMS-based systems to deliver general and customized advice and knowledge to farmer's devices. WebResults 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). %%EOF The dystrophic series are highly leached and highly weathered. In the present study, slop was generated from Digital elevation Model (DEM) by means of spatial analyst tool in Arc GIS, and the slop results were rated according to FAO [15] guide line. International Journal of Emerging Trends in Science and Technology 2: 2803-2814. Crop land has different quality conditions, which are reflected in different land suitability for agriculture. Copyright 2023 Elsevier B.V. or its licensors or contributors. It is useful to transform the rain-fed agricultural system which depends on rainfall into the combined rain-fed and irrigation agricultural system. On the other hand, land suitability has also been defined as the fitness of a given type of land for a specified kind of land use (FAO, 1976), which in analogy is the degree of fitness of a given type of cropland for production of a given crop species.

Modeling of land suitability for surface irrigation using analytical hierarchy process method in Belessa Districts, northwestern Ethiopia, https://doi.org/10.1016/j.heliyon.2023.e13937. The similarities with the clay class limits at family and series levels of the USA's Soil taxonomy are evident. The country is endowed with ample water resources with 12 river basins. The weather data were simulated by PhD students at the Sokoine University of Agriculture. The slope map of the study watershed was grouped in to five classes in percent for surface irrigation; flat or almost flat (0 3 %), gentle (3.1 - 5%), moderately steep (5.1 - 8%), steep (8.1-16%) and very steep (>16%) (Figure 6). Using Digital elevation Model (DEM) of the study area, the watershed was classified in to four slop classes (land mapping units). The suitability of soil for irrigation and agriculture are depend on soil fertility, moisture content, depth, and drainage [ 26 ]. The results showed that climate is the most important growth-limiting factor in the region; nonetheless, almost 40% of agricultural lands over the province are highly suitable for saffron production. 1). Nowadays, smart farming communities use the Internet to buy and sell their farming products like the systems developed by Juma etal. UW Libraries The LUR proposed by Van Zanten etal.

There are no unusual constraints on forest management for this property. Similar guidelines have been prepared by FAO for rainfed agriculture, extensive grazing and forestry. For example, 100 percent of the environmental impact of producing one kg of sunflower seed is now allocated to the sunflower oil as this is the only edible end-product (Fig. National, Sub-national/Province/District, Watershed/Basin/Landscape, Regional Office for Europe and Central Asia, Regional Office for Latin America and the Caribbean, Regional Office for the Near East and North Africa.

PTZ: We're glad you're here. SJSU King Library The factors were identified from different relevant sources and data availability. This meant that if soils with diagnostic horizon sequences not catered for in the system were found in nature, these could be added as new soil forms without disrupting the system. Soil parameters analysis and rating for surface irrigation: The selected physical and chemical soil prosperities (soil texture, electrical conductivity and calcium carbonate content) of the watershed were analyzed in laboratory; while soil depth and drainage were measured on fields based on the standards [14]. 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.

Fue etal. ICT-enabled learning and knowledge exchange: The introduction of the agro-advisory system in agriculture has improved the way farmers make their decisions and hence it has improved agricultural production through the dissemination of the knowledge to farmers (Barakabitze etal., 2017a,b; Fue etal., 2015). The pair-wise comparison matrix is a rating of the relative importance of the two factors regarding the suitability of the land.

Therefore, the area is potential for irrigation production with some limitations and under proper management it can benefit the local community to meet the food demand. xref Published by Elsevier Ltd. Nowadays, there has been an increase in the number of applications of ML techniques in the agriculture sector, mainly due to the analysis of big data from agricultural resources. Land having limitations, which appear so severe as to, preclude any possibilities of successful sustained use of the land in the given manner. 0000047884 00000 n Mourice etal. Hence, the soil in the present study area could be considered as deep soil which is highly suitable for surface irrigation [17]. Figured derived from Van Hal etal., 2019. Soil samples from each profile pit have been taken to analyze each selected soil physical and chemical properties. Analyzing climatic and edaphic information of the place in question and contrasting it with the environmental needs of the crop of interest has been used to improve the production and competitive advantages of various species worldwide. 21stCourse Professional Master, Remote Sensing and Natural Resources Evaluation 10 Nov 2000-22 June 2001-IAO. Shade . Second, assess the suitability of each land area currently occupied to produce feed to directly grow human food crops, using a crop suitability index (such as the Global Agro-Ecological Zones) to estimate the percentage of feed crop land that is also suitable for growing food crops. 85 0 obj Availability of irrigation leads to land use change as well as intensive cropping system. Scilit Williams DE (1949) A rapide manometric method for determination of calcium carbonate in soil. Land use land cover parameters While the soil chemical properties were highly suited for surface irrigation. Similar results were reported by Ibrahim, et al. This was due to the fact that knowledge about the soils was very poor when the system was constructed. According to the United Nations Food and Agriculture OrganizationFAO (1976): Land evaluation is the process of estimating the potential of land for alternative kinds of land use so that the consequences of change can be predicted.
