land suitability for irrigation

Academic Microsoft [12] lacks land suitability evaluation, it is important for surface irrigation development. Each soil form was subdivided into a number of soil series. However, David and Asamoah (2011) found videos as an effective tool to educate farmers in Ghana on complex topics in agriculture. Considering land suitability classes of Table2.9, OMW can be applied without limitations in areas characterized as S1. Link: Pan G, Pan J (2012) Research in crop land suitability analysis based on GIS.

The National Association of REALTORS reports that homeowners spent an average of $2453 in 2015 to install irrigation sprinklers. 0000001340 00000 n The study result could assist policy makers for better decisions during the development of irrigation projects in Omo-Gibe river basin. Lawn size will also be a factor in assessing costs for the installation of irrigation systems. The construction of a suitable model will have advantages as compared to traditional forecasting. Although, the study by Gebre, et al. The system had well-defined diagnostic horizons. Journal of the Dry lands 3: 214-219. Staal etal. Shade . They have some of the problems associated with dystrophic series but to a much more moderate extent. However, investment in advanced precision irrigation technologies still requires consistent and reliable supplies of water. LUR is calculated by defining the maximum amount of human digestible protein (HDP) that could be derived from food-crops on all land used to cultivate the feed required to produce one kilogram ASF, over the amount of human digestible protein in that one kilogram ASF (Eq. Such plans are known as programmatic HCPs and are often county- or even region-wide. The LUR proposed by Van Zanten etal. Soil type. An example of land suitability maps can be seen for the case of pistachio waste landspreading on the web site of another LIFE project, AgroStrat (LIFE-AgroStrat,2016, http://www.agrostrat.gr). Because changes in land use or an increase in arable land for ethanol purposes can have positive or negative environmental impacts (e.g., more greenhouse gases [GHG], indirect emissions, unsustainable harvesting, carbon sequestration, other land-use change effects, depleted soil nutrients, and increased water consumption). 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]. Such maps may assist authorities in decision-making regarding the level of land suitability to accept wastes. According to FAO standard guidelines for the evaluation of slope gradient, slopes which are less than 2%, are very suitable for surface irrigation. The objective of this paper was to determine whether the land in Belessa is suitable for surface irrigation. Adapted FAO (1976) suitability classes, as cited in Van Gool etal. Kellem Wollega zone is bounded by West Wollega Zone in the North, Buno Bedele Zone in the East, Ilu A/Bora Zone in South and Sudan in the West [13]. The Gibe River is called the Omo River in its lower valley south and south westwards from its confluence with the Gojeb River. If you are already a member of our network and need to keep track of any developments regarding a question you have already submitted, click "take me to my Query.". With this respect, the Geographic Information System (GIS) facilities will be extensively used. In order to protect the flooding of lower catchment, watershed management activities including the construction of flood protection ditches is recommended. Link. After all the required data were collected from different data sources, further analysis was carried out for each biophysical factor for a better understanding of their contribution in assessment of land suitability potential for irrigation. Soil Sci Am Proc 13: 127-129. It is drained by two major rivers from the highlands, the Gibe River flowing southwards and Gojeb River flowing eastwards. 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]. One way to measure this competition for land is to compute humanly-edible energy and protein conversion ratios (Wilkinson, 2011). Since the goal of forest management is to produce retirement and other income, there are cash-flow constraints related to periodic revenue generation. Furthermore, the LUR also implicitly assumes that all currently available grassland on marginal lands should be used for grazing. Agricultural land suitability analysis has been done to identify spatially the extents of highly suitable and moderately suitable areas for agriculture. 0000023533 00000 n Further land suitability analysis for sprinkler and drip irrigation should be carried out to increase the land area to be irrigated. N1 and N2 areas must be excluded from landspreading plans due to the high risk of degradation (environmental, economic, and societal), whereas an improvement or remediation plan should be developed and implemented (Doula etal.,2016).

The average soil Calcium carbonate status( CaCO3) values, were found in the ranges of 3.2-5.1 percent. They are infertile and strongly acidic, characterized by aluminum toxicities and have serious plant nutrient management problems, such as extremely high P fixing capacities into non-available forms. The capability index and its suitability class for surface irrigation of each land mapping unit(LMU) is presented in Table 6. The greater the relative economic value of the main product, sugar, or a co-product, the greater the portion of LU related to the cultivation of the underlying primary product allocated to this main or co-product. The AEZ, as a tool, and novel technologies, such as Maximum Entropy Modeling (MaxEnt), the Soil and Water Assessment Tool, remote sensing, GIS, and precision agriculture, may contribute to achieving sustainability goals, supporting major strategic decisions to improve crop yields and the ethanol production value chain, and adding value through bioproducts, without affecting the production of food and feed (Dufoss etal.,2016). 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. It then lists the factors that may affect a crop, its irrigation and management (in the form of land use requirements or limitations) and the land qualities or land characteristics, inputs and land improvements that should be evaluated. Table 2.9. Churi etal. In addition to river proximity, electrical conductivity (EC) of the river water was included as an information. International Journal of Emerging Trends in Science and Technology 2: 2803-2814. The similarities with the clay class limits at family and series levels of the USA's Soil taxonomy are evident. Evaluating land suitability of a given watershed is vital to predict potential and limitation of the land for surface irrigation. Published by Elsevier Ltd. This requires implementing a measure expressing a nutritional value that includes multiple nutritional aspects, and not only protein or calorie contents such as the nutrient density score (Van Kernebeek et al., 2014). Distance to water sources: It is important to make sure that there will be no lack of irrigation water. 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. , DOI: 10.37421/idse.2020.9.245 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. In other words, it does not account for the competition between humans and animals for land.

Link: Briza Y, Dileonardo F, Spisni A (2004) Land evaluation in the province of ben Slimane, Morocco. Environmental impact allocation of the co-products resulting from the multifunctional process sunflower seed crushing under economic and circular allocation. In the current situation, feed-food competition is therefore higher in monogastric production systems compared to the ruminant systems.
Fue etal. (2014) and Fue (2015) developed and deployed a wireless-based system for controlling water during irrigation by sensing the soil moisture, and he used proximal wireless valve control to open and close water supply systems. How do you ensure access to agricultural input, technology, market knowledge and capital to smallholders and micro-businesses in order to reduce constraints to diversification, including market availability and size, land suitability and rights, irrigation infrastructure and labor supply? [9] and the average salinity ranges from 0.03 to 0.04 dS/m (Table 3). 0000027661 00000 n

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. Both maps show three different zones with high spatial similarity. 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). By continuing you agree to the use of cookies. Bear in mind, however, such land use change would lead to adverse effects such as soil carbon and biodiversity losses, Therefore, this possible alternative use of grassland is often undesirable from a more holistic perspective that addresses environmental indicators beyond cropland use. The northern part of the basin has a number of tributaries from the northeast of which the largest are the Walga and Wabe rivers. Lawn size will also be a factor in assessing costs for the installation of irrigation systems. Here precision irrigation could become important, particularly for supplemental irrigation. Factors to consider. In contrast, coarse sandy series have very low water storage capacities per unit soil depth (Laker, 2021). CrossMark Online commerce tools: The spread of the Internet brought e-commerce. International Journal of Scientific and Research Publications 3. 0000022386 00000 n The watershed was classified in to four lands mapping units, based on three soil profile pits were opened at each land mapping unit. In other words, the opportunity costs of land for human food production are not considered (Van Zanten et al., 2016). The purpose of weighting in land suitability analysis is to determine the importance of each factor relative to other factors. It is often simply stated that sandy soils have low plant-available water capacities. Avalon is one of the most important soils for rainfed cropping in the maize quadrangle, especially in the marginal rainfall western parts where mainly white maize is produced. The matching process consists itself of different steps: (i) matching the class-determining factors individually, (ii) evaluating the interactions between individual factors, and (iii) evaluating the importance of each individual factor in its impact on land productivity or the benefit/cost balance. WorldCat So, to endeavor this gap, the present study was evaluated the suitability of Gudina Wacho watershed for surface irrigation development using its soil and slop parameters of the watershed. 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). This bulletin is written for all concerned with land evaluation for irrigation planning, and is divided into two parts. Monogastric systems only derive a value below 1 if they are fed with food waste or co-products of a low value for other use. Appreciably inferior to S1 land. Google Scholar It explains economic criteria for separating land which is 'Suitable' from land which is 'Not Suitable' first In 'provisionally - irrigable' and later in 'irrigable' classifications. Received: 20-Aug-2019 Irrigation in Ethiopia is considered as a basic strategy to alleviate poverty and hence to achieve food security and improve the economy of the farming community through generating additional income during the dry season. With this tool, models to predict the environmental conditions such as humidity, temperature, rainfall and wind up to the year 2050 are available for educational use. Based on the finding of this study, for the area which have slope above 8% (76.16% of the total area), land leveling operation and/or soil conservation work have to be incorporated to break surface slope and to make it suitable for surface irrigation. Last, assess the amount of HDP in one kg ASF, the denominator (Van Zanten etal., 2016). 84 33 The soil data (physical property; texture, drainage class and soil depth) covering the study area was accessed from the FAO website Harmonized World Soil Database, in Environmental System Research Institute (ESRI) shape file format (version 1.21) [15]. The principal categories of data required are dealt with under the headings: general characteristics of the project area, topography, soils, climate, water resources, drainage, land use, vegetation and fauna, environmental health, social and economic data. Land suitability evaluation: After rated the soil and slop parameters, capability index (Ci) for surface irrigation was calculated using parametric evaluation approach (equation below) [9]. Land Suitability Classes (FAO,1976). Rashid Sorkh Abadi et al. [13] and Kassa, et al. 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. In terms of global food supply, however, livestock systems with an LUR lower than 1 are more efficient than crops because they produce more HDP per m2 than crops. Despite there are various scales to rate the related stakeholders judgments, the 1-9 point scale has strongly been recommended to be used as an acceptable scale in the AHP and it was implemented in this study too. These new restrictions may cause confusion on the part of landscapers and homeowners. Webland suitability for surface irrigation development are river proximity, road proximity, and market access. Moderately severe limitations which reduce productivity or benefits or increase required inputs. Estimation of potential yield for each agroecological zone or land suitability class is another important problem, which is ignored in the above-mentioned studies. A scale of importance is broken down from a value of 1 to 9 (Table 3). Soil texture is important factor of soil physical analysis for surface irrigation suitability evaluation as it determines pore spaces of the soil which influence the soil permeability and infiltration rate [15]. Caution must be used on portions of the property located on steep slopes, but no slope is so steep as to exclude intensive forest management. The process of land suitability classification is the appraisal and grouping of specific areas of land in terms of their suitability for defined uses. The rate of the suitability is the function of characterization and alignment of land quality in to orders and classes in the framework of its fitness for irrigation [11,12]. The worksheet generates an annual Appropriate management and selection of applicable irrigation method is a prerequisite for better utilization of land resources which help to optimize and sustain the productivity of these land resources [10]. Abraham M, Daniel H, Abeba N, Tigabu D, Temesgen G, et al. Link: KWZ (Kellem Wollega Zone Agricultural office) (2020) Annual report, unpublished. Distance to the existing river was calculated in ArcGIS tool by projecting the locations to a Mercator (UTM) Zone 37N. WebSuitability of the water for irrigation is variable and is dependent principally on "potential salinity" of the water, soil permeability, and type of crop. So far, no research has been conducted in this area to determine whether the land is suitable for surface irrigation. 21stCourse Professional Master, Remote Sensing and Natural Resources Evaluation 10 Nov 2000-22 June 2001-IAO. It is necessary to determine spatially and quantitatively the potential to expand arable land without jeopardizing food and feed production. Also, modelling tools require well-designed systems to visualize data. Igbadun etal. 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).

Nowadays, smart farming communities use the Internet to buy and sell their farming products like the systems developed by Juma etal. 0000027551 00000 n Several researchers in Africa have conducted research to get integrated methods and frameworks of monitoring food supply and security (Dempewolf etal., 2015; Dempewolf etal., 2016; Omran, etal., 2010; Tadesse etal., 2008; Barakabitze etal., 2017a,b). WebGauge cost considerations. Publons (2016) found increased soil stability with increasing degree of weathering. Also, GIS has been used in Nigeria and Egypt to evaluate land and soil suitability for crop production decision support (Joshua etal., 2013; Kawy and El-Magd, 2013). Hydrology 8: 86-95.

However, capturing the complete nutritional values within the allocation methods is complex. And, pH (soil reaction) was measured using a glass electrode pH-meter [14]. Land use land cover parameters Thus, increased degree of weathering is associated with decreased problems with soil compaction, soil crusting, erosion, etc. These new restrictions may cause confusion on the part of landscapers and homeowners. PTSMCD showed a very high consistent and of better quality (R2 ranged from 0.98 to 0.99) for monthly data while MarkSim showed relatively low from 0.64 to 0.91. Water Resour Manag. The climate of the area is a hot and humid type. Hence, future surface irrigation development is feasible based the land features and river proximity. We also thank to the peasants and Agricultural experts in the study area. If factor X is exactly as important as Y, this pair receives an index of 1. Every property has area and, Perspectives on soil series classification based on comparison of two contrasting scenarios, Each soil form was subdivided into a number of soil series. Feed-food competition can occur directly or indirectly. The factors were identified from different relevant sources and data availability. Where, Ci = Capability index for surface irrigation. Table 3: The AHP Pair-wise comparison scale and definition [20]. Land having limitations, which may be insurmountable. Link: Gebre G (2020) Impact of Small Scale Irrigation Development on Farmers Livelihood Improvement in Ethiopia: A Review. Where a landscape characteristic does not meet the requirements for a particular land use, it constitutes a potential limitation or constraint. Constraints are commonly rated to express the degree of severity to which they may impair land use. Thus, to bring food security in the national as well as in house hold level, improvement and expansion of irrigated agriculture must be enhanced as noted by Negash [11]. This is an open-access article distributed under the terms of the Creative Commons Attribution License, which permits Also, several scientists have used smart simulation tools to simulate crop performance in Africa. 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. Land suitability is the fitness of a given area for a land utilization type (or land use), or the degree to which it satisfies the land user. Changes in water quality are not consistent throughout the subarea. 0000027485 00000 n 0000021699 00000 n The 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. It encompasses parts of two National Regional States; Oromia which occupies the north-eastern part of the basin and the rest of the basin, this study focused, is situated in the Southern Peoples Regional States (SNNPRS). These texture differentiations have important practical significance, for example in regard to the plant-available water content of soils. 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]. However, the practice of using ICT like phones for advice has been common among men compared with women farmers (Isaya etal., 2018). The reader is advised to use these Guidelines selectively, as not all the factors listed will be relevant in a given evaluation. Creative Commons Attribution 4.0 International License. The National Association of REALTORS reports that homeowners spent an average of $2453 in 2015 to install irrigation sprinklers. Clay soils hold water longer than loamy or sandy soils do, but it also takes longer for water to absorb. WebThe term land suitability for agriculture is defined as the lands ability to reach potential yields in a number of crops. To conclude, the LCA approach provides insights in strategies to minimize the land-footprint while the LUR provides insights in strategies to minimize feed-food competition. ICT-based (social) networking solutions: Through social media, such as Facebook, twitter, blogs, WhatsApp and others, the smart farming communities have been exchanging knowledge (Cox and Sseguya, 2015). The weight of each parameter was calculated using an 88 pairwise comparison matrix. The system quickly found wide acceptance in the country, both among soil scientists in general (not only pedologists), although there were a few critics (MacVicar, 1978), and the users of soil information. (2016) developed a land use efficiency assessment method called Land Use Ratio (LUR) to deal with feed-food competition. Land use land cover parameters The assessment of land suitability for irrigation is critical for designing and implementing worthwhile irrigation projects and increasing agricultural production.

/Contents 87 0 R endobj 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). (2019) compared economic and food-based allocation in an LCA of a novel egg production system - called Kipster - that only feeds chickens with products unsuitable or undesired for human consumption. 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. First, quantify the land area occupied (LOij) to cultivate the amount of each feed ingredient (i=1,n) in the different countries of origin of the feed (j=1,m) needed to produce one kg ASF. This kind of test land suitability analysis is an essential starting point for the development. J Agric Sc Food Technol 7(3): 302-309. Strongly more important / Much more important. Chapter 9 outlines the role of land suitability classification in the appraisal of irrigation development projects for the purposes of either feasibility appriasal or project implementation and monitoring. In the application of the AHP method it is important that the weights derived from a pairwise comparison matrix are consistent. `k>AYbeUOrUtR VvnUW o"qV@:2Q!zc4 Similar guidelines have been prepared by FAO for rainfed agriculture, extensive grazing and forestry. Outdoor rainfed and irrigated crops are particularly sensitive, both directly from changes in rainfall and temperature and also indirectly, as any change in climate will also impact on the agricultural potential of soils by modifying soil water balances and changing land suitability for production (Daccache et al., 2012). If X is much more important than Y, the index is 9. Moderately/Slightly less important/ Experience and judgment slightly favor one over the other.
