WebLand suitability for irrigated agriculture was evaluated by considering the Food and Agriculture Organization (FAO) criteria. Each approach makes assumptions about the nature of the problem and comparing the results of the two different optimization strategies provides a great opportunity to define strategies of sustainable land management. In other words, it does not account for the competition between humans and animals for land. Link. In the 1977 classification system, the soils were classified in two different series on the basis of the clay content of the B21 (1977 term) horizon, one falling in the 615% clay range with fine sand (Bleeksand series) and the other in the 1535% clay range (Soetmelk series). The process of land suitability classification is the appraisal and grouping of specific areas of land in terms of their suitability for defined uses.

Published: In the present study, the soil textural class of the watershed was determined based on the particle size distribution. The Tuljo and Gilgel Gibe rivers are important rivers that drain to the Gibe [14].

(2002) used GIS to analyze technology use and land use among Kenyan enterprises. WebAn HCP that individual landowners can join may already exist in a given area. Soil samples from each profile pit have been taken to analyze each selected soil physical and chemical properties. Analytical Hierarchy Process (AHP) (Figure 3), a well-known Multi-Criteria Decision Analysis method developed by Saaty [23] was used to express the relative importance of each suitability factors.

In overall, most of the study area is suitable for irrigation (71% excluding the national parks; 7% is S1 and 64% is S2) whereas the remaining 29% is not recommended for surface irrigation. Kiobia etal. Soil pH results from the laboratory analysis showed that the average soil pH (H2O) values were found in the ranges of 5.74 to 6.04 (Table 3), which was moderate acidic Sys, et al. Moreover, there was no significant difference in ECe values. Factors used to assess land suitability for irrigation.

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. Van Zanten etal. Since the goal of forest management is to produce retirement and other income, there are cash-flow constraints related to periodic revenue generation.

Way less important/ Experience and judgment strongly favor one over the other. 17-Jun-2020 GrowKudos The, Van Hal, Weijenberg, De Boer, and Van Zanten (2019).

Land having no significant limitations to sustained application for a given land use or only minor limitations. 0000023133 00000 n The eutrophic series are relatively poorly weathered and require different soil fertility management approaches. A scale of importance is broken down from a value of 1 to 9 (Table 3). UC Davis has created an irrigation scheduling worksheet that can help. The criteria used for series differentiation were selected to reflect practical differences related to land suitability and soil management between series. In contrast, the ML-based method is not as much influenced by such limitations and is preferred for conducting the agriculture assessment and monitoring. Neighbors are located near the property boundaries and may be impacted by some management activities, especially smoke from controlled burns. Link: KWZ (Kellem Wollega Zone Agricultural office) (2020) Annual report, unpublished. 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.

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. The wetlands restoration project is funded under the NRCS Wetlands Reserve Program (U.S. Department of Agriculture, 2014) and must follow program requirements. The development of land suitability maps for OMW distribution is strongly recommended. 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). Link: FAO (1985) Guidelines: Land Evaluation for Irrigated agriculture. Similarly, Abraham, et al.

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.

GIS has been used in Nigeria to assess rainfall variability impacts on crop yields (Odekunle etal., 2007). However, David and Asamoah (2011) found videos as an effective tool to educate farmers in Ghana on complex topics in agriculture. McGill The assessment of land suitability for irrigation is critical for designing and implementing worthwhile irrigation projects and increasing agricultural production. The system ranked the extension officers who were the best in providing answers to farmers. 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. Computer Comput Technol Agric 365: 314-325. In shady areas, use less water than the recommended rates. 0000023975 00000 n

Overall land suitability/weighted overlay: Potential irrigable land was obtained by creating irrigation suitability model analysis which involves weighting of values of all individual data sets. Distance to water sources: It is important to make sure that there will be no lack of irrigation water. In addition to river proximity, electrical conductivity (EC) of the river water was included as an information. 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. The assessment of land suitability for irrigation is critical for designing and implementing worthwhile irrigation projects and increasing agricultural production. Sand grades were classified as fine, medium or coarse (MacVicar et al., 1977; Van Watt and van Rooyen, 1995). FIGURE 5.3. Link: Reddy O, Maji GE, Gajbhiye KS (2002) GIS for morphometric analysis of drainage basins. GIS India 11: 9-14. Therefore, the application of successful methodological frameworks internationally recommended for this purpose is essential, because phenomena, such as soil erosion, loss of nutrients and organic matter, decrease energy efficiency, reduce biodiversity, cultural erosion and excessive use of agrochemicals, are causing this decline in soil quality (Huang etal.,2016). Florence, Italy. Classification of individual factors: According to FAO [5], each factor determining the suitability of the land for irrigation was classified into four classes such as highly suitable (Class S1), moderately suitable (Class S2), marginally suitable (Class S3), currently not suitable (Class N) (Table 2 and Figure 2) and data layers were prepared for further overlay [21,22]. (2017) developed a climate data visualization and interaction tool (http://41.73.194.138/transsecmarket/). Very high risk of negative economic, environmental, and/or social outcomes if not managed. 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. The methodology, therefore, does not account for differences in consumption of humanly-edible products by livestock or differences in suitability of land used for feed production to directly cultivate food crops. 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. HDPj is the maximum amount of human-digestible protein (HDP) that can be produced per m2 yr1 by direct cultivation of food crops in country j. Lawn size will also be a factor in assessing costs for the installation of irrigation systems. The system helps the farmer to solve their real-world problems. Adapted FAO (1976) suitability classes, as cited in Van Gool etal. While the soil chemical properties were highly suited for surface irrigation. The mesotrophic series are moderately leached and moderately weathered.

[13], it is considered as a very significant resource within Ethiopia. Soil type. They are based on the relative proportions of fine, medium and coarse sand. The process of land suitability classification is the appraisal and grouping of specific areas of land in terms of their suitability for defined uses. Groundwater is a viable option for supplementing surface water resources for irrigation in several basins in the country. Link: Kassa T, Van Rompaey A, Poesen J (2010) Land Suitability Assessment for Different Irrigation Methods in Korir Watershed, Northern Ethiopia. % On the other hand, areas of intensively used grasslands with low species diversity and high nutrient inputs and correspondingly low ecological value, could be transformed into croplands. The limiting factors were slop, soil texture and drainage.

This kind of test land suitability analysis is an essential starting point for the development. It is necessary to determine spatially and quantitatively the potential to expand arable land without jeopardizing food and feed production. Irrigation would provide farmers with sustained livelihoods and improve their general well-being. 0000115456 00000 n

The model was then used as a yield prediction tool over the province and the resulting yield was spatially interpolated with GIS for mapping different zones based on saffron yielding ability. 0000027551 00000 n

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. 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). Fue etal. The land suitability parameters such as soil properties, slope, land use and land cover were used to identify the suitable irrigable land. The National Association of REALTORS reports that homeowners spent an average of $2453 in 2015 to install irrigation sprinklers.

Information systems: Use of GIS has been well received and adopted in Africa like in other parts of the world. Very much more important/Far more important. The suitability analysis indicated that, 11.75% and 82.4% of the study area based on slope and soil depth respectively is suited for surface irrigation. 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. Churi etal. General Administration for Development Cooperation Agriculture, Brussels, Belgium 199. More discussions on Soil taxonomy: a binomial system for South Africa (MacVicar et al., 1977) and the classification of series in other soil forms in the system can be found in Laker (2003, 2021). 85 0 obj

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. Link: Briza Y, Dileonardo F, Spisni A (2004) Land evaluation in the province of ben Slimane, Morocco. The suitability class of a land parcel with respect to river proximity is determined by its distance in relation to the perennial rivers. Experimental Agriculture 47: 57-69.

The procedure provides for a sifting out of considerations deserving special emphasis in order to avoid needless investigations and unnecessary expense. ScienceDirect is a registered trademark of Elsevier B.V. ScienceDirect is a registered trademark of Elsevier B.V. The result will recognize to the local government (regional and district land use planners), and it could serve as a base line for researchers and policy makers concerning land use planning and management for irrigation. Moderate to high risk of negative economic, environmental, health, and/or social outcomes if not adequately managed. Challenges in conceiving early-stage development pathways to ensure the food and nutrition security of smallholders and their local, national and transnational consumers are manifold. Comparison of these maps with the maps of actual yields of saffron over the province indicated that yields predicted using monthly average temperatures had the highest accordance with actual yields (Fig. If the CR is >0.1, the comparison matrix should be revised again.

(2016) is based on the LCA framework, as most LCA studies use economic allocation for the LU between the multifunctional processes. Using the MCDMAHP method Rashid Sorkh Abadi et al. Last, assess the amount of HDP in one kg ASF, the denominator (Van Zanten etal., 2016). 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. Such plans are known as programmatic HCPs and are often county- or even region-wide. \15rG"TxQl}{&2Pudi+.L\ This study provides beneficial information that can be useful to measure the implication of agriculture management policies. Every property has area and land suitability constraints.

Clay soils hold water longer than loamy or sandy soils do, but it also takes longer for water to absorb.

%PDF-1.5 Good drainage of the site is essential to allow the continuous movement of water and salt through the profile [14]. Steps used in the AHP method to establish weights as a flow chart [19]. This was due to the fact that knowledge about the soils was very poor when the system was constructed. In the present study, the soil drainage of the watershed (all land units) was classified as moderately drained (Table 2), which is considered as moderately suitable for surface irrigation [18]. 0000131532 00000 n Ambient temperature of the Zone ranges from 12 320C. WebLand suitability for irrigated agriculture was evaluated by considering the Food and Agriculture Organization (FAO) criteria. The northern part of the basin has a number of tributaries from the northeast of which the largest are the Walga and Wabe rivers. Maria K. Doula, Konstantinos Komnitsas, in Olive Mill Waste, 2017. 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. For a "less important" relationship, the fractions 1/1 to 1/9 are available: if X is much less important than Y, the rating is 1/9. Far more important to extremely more important, Far less important to extremely far less important, Absolutely more important / Extremely more important. 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).

(2016) developed a land use efficiency assessment method called Land Use Ratio (LUR) to deal with feed-food competition. The concepts of 'provisionally-irrigable' and 'irrigable' land at successive levels of detail, and the use of productivity and economic indices to evaluate land suitability classes are introduced in this chapter. Before turf is removed, initial steps include: assessing your current irrigation system and identifying needed modification, finding the plants that work best in your climate, characterizing your soil, and assessing sun conditions in your yard. If factor X is exactly as important as Y, this pair receives an index of 1. Based on the classified slops, three soil profile pits were opened at each land mapping unit (LMU) (Figure 2). WebGauge cost considerations. 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, Precision farming and IoT case studies across the world, Agricultural Internet of Things and Decision Support for Precision Smart Farming, Joshua etal., 2013; Kawy and El-Magd, 2013, Dempewolf etal., 2015; Dempewolf etal., 2016, Tadesse etal., 2008; Barakabitze etal., 2017a,b, Barakabitze etal., 2017a,b; Fue etal., 2015, Land use modeling: from farm to food systems, =1,m) needed to produce one kg ASF. In addition, auger observations for soil depth and drainage measurement for soil drainage evaluation on each representative site were made. 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. (2017) called market access information system (http://41.73.194.138/transsecmarket/). (2013) used a simulation model for irrigation known as Irrigation Scheduling Impact Assessment Model (ISIAMOD) to simulate leaf area index, cumulative biomass production, final biomass yield at harvest and grain yield of a maize crop and obtain good results (parameters simulated were above 80%), which is good to be adopted by the growers. Crop land has different quality conditions, which are reflected in different land suitability for agriculture. Link: Awulachew SB, Ayana M (2011) Performance of irrigation: An assessment at different scales in Ethiopia. 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. [12] lacks land suitability evaluation, it is important for surface irrigation development. Sustain.

Irrigat Drainage Sys Eng 9(2020): 245 doi: 10.37421/IDSE.2020.9.245 It is also important to note that the part of the soil profile in which these were determined in the South African system corresponded closely with the soil texture control section in Soil taxonomy. In the application of the AHP method it is important that the weights derived from a pairwise comparison matrix are consistent. This paper has, unfortunately, never been published.

Potential negative economic, environmental, health, and/or social outcomes if not adequately managed. Sand grade classes are identified by using a sand grade triangle. In shady areas, use less water than the recommended rates. Overall severe limitations; given land use is only marginally justifiable, Limitations not currently overcome with existing knowledge within acceptable cost limits, clay loam/ sandy clay loam/clay (light)/silty clay loam, Constraints (Forest, built-up, water, wetland). The assessment of land suitability for irrigation is critical for designing and implementing worthwhile irrigation projects and increasing agricultural production. The major problem associated with this rainfed agriculture is the high degree of rainfall variability. It was found that LMU-3, covering an area of 1154 ha (27.4%) was currently not suitable (N1) (Figure 6) for surface irrigation due to the high slop gradient. Factors to consider. Land use/Land cover (LULC): The 2018 LULC of the Omo-Gibe river basin was assessed and mapped using Landsat-8 satellite images. CrossMark This method is relatively cost-effective and compatible with African settings. All gradations are possible in between. 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. [13] and Kassa, et al. HCPs can also include conservation measures for vulnerable plant and animal species that are not listed federally as endangered or threatened.

Based on the LULC, 54.42% is highly suited for surface irrigation. 0000000015 00000 n 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. By continuing you agree to the use of cookies.

Therefore, this result will be important to increase crop production in the study area, by implement surface irrigation in highly and moderately suitable lands.

The limiting factors were slop, soil texture and drainage. For our future food supply, it might be better not to use highly productive croplands to produce animal feed because, regardless of how efficiently animals are raised, using these land resources to produce biomass streams for direct human consumption is always more land use efficient (Foley etal., 2011). Strongly more important / Much more important. Due to shallow water table depth and fine textured soil of the study area has poor drainage and workability problems under excessive moisture regimes. Strategies for convergence that relate to best-practice, innovation and collaborative action in methods and technologies embodied in seeds, breeds and feeds as well as in business processes and market institutions along the agriculture and agri-food chains, need to be examined. <> Nil to minor negative economic, environmental, health, and/or social outcomes. Omo-Gibe River Basin is situated in the South-West part of Ethiopia, between 430 and 930 N latitude, and between 35 and 38 E longitude (Figure 1). . Except for the streamside hardwood areas, all of the property is suitable for loblolly pine plantations. For this study, physical soil factors (soil type, soil drainage, soil depth, and texture classes) are considered as the primary soil factors. trailer The process of land suitability classification is the appraisal and grouping of specific areas of land in terms of their suitability for defined uses. Although the California drought has been declared over in early 2017, state regulators continue to impose restrictions on landscape watering. DOI: 2021 Weldeabzgi GG, et al. 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. /Contents 87 0 R

Performing a agroecological zoning scheme at large scale (e.g., province) is the best method for separating homogeneous arable lands. Each soil form had a specific sequence of diagnostic horizons (Laker, 2021; MacVicar et al., 1977). Soil texture was determined by the hydrometer method [16]. Land use land cover parameters

Several countries including Egypt researchers have developed decision support systems for food security tools (Omran etal., 2010). Part Two provides guidelines for developing the specifications and critical limits of class-determining factors, which include agronomic factors, management, land development and improvements, conservation and the environment, and socio-economic factors.

0000022386 00000 n 5.3). 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. Some research studies related to the successful use of ML techniques for crop monitoring under various climatic conditions are presented in Table15.2. 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.

ERX%Y>1][mIv|K To improve classification accuracy and reduction of misclassifications, post-classification refinement was therefore used for simplicity and effectiveness of the method [17-20]. The dystrophic series are highly leached and highly weathered. Soil samples from each profile pit have been taken to analysis each selected soil physical and chemical properties such as texture, CaCO3 status, Electric conductivity (ECe) and pH. The fact that most of the parameters used in the classification can be directly related to some practical land use implication; The fact that no difficult terminology was used. endobj In reference to soil drainage class 70% of Omo-Gibe river basin is accounted for suitable class (S1 and S2) at present condition and 17.5% is classed under marginal suitability class. Chapter 2 explains the basic principles and terminology, and provides a summary of the procedures to evaluate and classify land for a specific use. It should be noted that for preventing bias thought criteria weighting the Consistency Ratio was used (CR). Link: Sys C, Vanranst E, Debvay J (1991) Land evaluation. Lawn size will also be a factor in assessing costs for the installation of irrigation systems. Similar guidelines have been prepared by FAO for rainfed agriculture, extensive grazing and forestry. Estimating the potential yield of saffron in homogeneous zones using simulation models is required to provide a quantitative measure for the qualitative land suitability classes.

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). If water is in short supply during some part of the irrigation season, crop production will suffer, returns will decline and part of the scheme's investment will lay idle [7]. 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]. These new restrictions may cause confusion on the part of landscapers and homeowners. 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.

After going through a series of unpublished changes and refinements it was eventually published as Soil classification: a binomial system for South Africa (MacVicar et al., 1977). Staal etal. They recommended using PTSMCD for historical data ranged from 10 to 15 years. Part Two provides further technical guidance on developing the specifications and critical limits of factors that are commonly used to determine land suitability class. The chapter explains how to verify both the economic and financial viability of a project from the national and farmers' viewpoints. 0000132334 00000 n A consistency ratio (CR) of 0.10 or less indicates a reasonable level of consistency [23].
