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. Constraints and opportunities for enhancing the system, International water Management Institute contributions, Addis Ababa. Journal of Resources Development and Management 62: 10-18. So far, no research has been conducted in this area to determine whether the land is suitable for surface irrigation. A ratio below 1 means the animals produce more edible energy or protein than they consume and implies more efficient land use (meaning that direct feed-food competition is avoided). 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]. Such maps may assist authorities in decision-making regarding the level of land suitability to accept wastes. (2005) tested the weather data generators such as MarkSim and Parched Thirst Simulator of Missing Climate Data (PTSMCD) to generate synthetic missing data. In the Hutton and Clovelly forms, the two main forms in this group, and the Griffin form the latter was split into 3555% and>55% clay. They support planning and management by identifying land resource potentials or problems through the collection, evaluation, and presentation of land resources data [9].

The land may be considered in its present condition or after improvements. 2) is defined as. 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. WebGauge cost considerations. Then to calculate the weight, a normalized comparison matrix was created: each value in the matrix was divided by the sum of its column. It should be noted that for preventing bias thought criteria weighting the Consistency Ratio was used (CR). The suitability of soil for irrigation and agriculture are depend on soil fertility, moisture content, depth, and drainage [ 26 ]. As it was seen from auger observation and profile description of the soils, soil depths at all sampling points were greater than 100 cm (Table 2), rock out crop was no observed. 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). The limiting factors were slop, soil texture and drainage. 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]. This bulletin is written for all concerned with land evaluation for irrigation planning, and is divided into two parts. Table 1: Land suitability classification [5]. Accordingly, Sys, et al. Copyright 2023 Elsevier B.V. or its licensors or contributors. In contrast, the ML-based method is not as much influenced by such limitations and is preferred for conducting the agriculture assessment and monitoring. Also, several scientists have used smart simulation tools to simulate crop performance in Africa. 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. WebAn HCP that individual landowners can join may already exist in a given area. The climate of the area is a hot and humid type. Soil Sci Am Proc 13: 127-129. The dystrophic series are highly leached and highly weathered. Although the California drought has been declared over in early 2017, state regulators continue to impose restrictions on landscape watering. The factors were identified from different relevant sources and data availability. According to Woodroofe et al. Our deepest thanks go to the staff members of Hawassa University, Institute of Technology, Faculty of Biosystems and Water Resource Engineering for their valuable comments and experts suggestion. 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. In order to sustainably develop the area for irrigation development; land leveling operation or soil conservation work has to be incorporated to break surface slope and to make it suitable for surface irrigation. 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). 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]. \15rG"TxQl}{&2Pudi+.L\ WebLand suitability is the fitness of a given type of land for a defined use. VU on WorldCat 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). 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). 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].

These regression models were then used to generate three yield maps where zones were separated according to saffron yield. [9], suggested a parametric evaluation approach for surface irrigation suitability evaluation which is concern on soil physical properties (soil texture, soil depth and drainage), soil chemical properties (salinity/alkalinity status such as calcium carbonate content and gypsum content of the soil), and slop. 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. (2017) and Mourice etal. These represent the amount of energy or protein in animal feed that is potentially edible for humans compared to the amount of energy or protein in that animal product that is edible for humans. GIS has been used in Nigeria to assess rainfall variability impacts on crop yields (Odekunle etal., 2007). Hence, future surface irrigation development is feasible based the land features and river proximity. The northern part of the basin has a number of tributaries from the northeast of which the largest are the Walga and Wabe rivers. The distances were

The distances were The similarities with the clay class limits at family and series levels of the USA's Soil taxonomy are evident. [21] found that these parameters were not limited factors for surface irrigation in Northern Ethiopia. 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. Estimation of potential yield for each agroecological zone or land suitability class is another important problem, which is ignored in the above-mentioned studies. Agriculture is a mainstay of Ethiopian economy. 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.

Most notable is the increasing burden of environmental protection and its consequent impacts on water resources (both supply and allocation) for irrigated agriculture (Knox et al., 2010). This food-based allocation assigns zero environmental impact to byproducts that humans cannot or do not want to consume, whereas the determining (food) product is given full allocation. 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. Hence, future surface irrigation development is feasible.

In regard to water resource proximity, majority of the study area (80.85%) is currently suitable (S1). In other words, it does not account for the competition between humans and animals for land. This consistency index was then compared to a random index (RI). 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. Thus, for n=3 and n=4, conventionally it is required that CR0.05 and 0.08, respectively to be acceptable. Citation: Rediet Girma, Eshetu Gebre and Teshale Tadesse. Copyright 2023 Elsevier B.V. or its licensors or contributors. Factors, such as type and degree of macro-structure, degree of wetness, soil color (both in terms of Munsell color definition and homogeneity of color), etc., were used in the definitions of diagnostic horizons. 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. UC Davis has created an irrigation scheduling worksheet that can help. Considering land suitability classes of Table2.9, OMW can be applied without limitations in areas characterized as S1. 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. 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. Semantic Scholar In regions where rainfed agriculture is dominant, changes in the timing, distribution, and reliability of rainfall may force a gradual switch to irrigated production, to maintain crop yields. Land having limitations, which may be insurmountable. Dagnenet S (2013) Assessment of Irrigation Land Suitability and Development of Map for the Fogera Catchment Using GIS, South Gondar. The land suitability parameters such as soil properties, slope, land use and land cover were used to identify the suitable irrigable land. Figure 9.18. The middlemen are also known as market masters. For n5, a consistency ratio of 0.10 or less is acceptable. Soil depth refers to the thickness of the soil materials which provide structural support, nutrients and water for plants [14]. The results showed that the LMU-1, 2 and 4, with a total area of 3064 ha (72.6%), were slightly suitable (S3) (Figure 7) for surface irrigation. Hedley, R. Smith, in Encyclopedia of Agriculture and Food Systems, 2014. 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. Google Scholar Biplab M, Gour D, Sujan S (2017) Land suitability assessment for potential surface irrigation of river catchment for irrigation development in Kansai watershed, Purulia, West Bengal, India. The assessment of land suitability for irrigation is critical for designing and implementing worthwhile irrigation projects and increasing agricultural production. Due to the moderately acidic nature of the soils of the study area, the ECe values were negligible. van Zanten, A. Frehner, in Food Systems Modelling, 2022. Except for the streamside hardwood areas, all of the property is suitable for loblolly pine plantations. Far more important to extremely more important, Far less important to extremely far less important, Absolutely more important / Extremely more important. Based on soil depth, 82.4% of the study area is potential suitable for the intended uses; the drainage class scores 70% suitability; 80% the soil texture was clay dominant hence it was moderately suitable for surface irrigation. HCPs can also include conservation measures for vulnerable plant and animal species that are not listed federally as endangered or threatened. 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. 0000133056 00000 n Limitations are so severe as to preclude successful sustained use of the land. 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). Sound information on watershed characteristics such as soils, slop and other land characteristics provide a basis for decision making on proper utilization and management of natural resources. For agriculture and land suitability assessment frameworks, various ML-based methods are commonly used. 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]. Eight factors/parameters such as soil type, soil depth, soil texture, soil drainage, slope, distance from a water supply, and land cover were used to evaluate the suitability of the area for surface irrigation. In addition, land cover/land use types are considered as limiting factors in evaluating suitability of land for irrigation [8].

Useful checklists are included for soils, climatic and socio-economic data to be compiled. To increase biodiversity, we recommend, to identify which grasslands can be considered available for animals, which for crop production, and which should be left for rewilding or other conservation strategies (Van Zanten etal., 2018). Communication was effective because farmers, extension officers, fertilizer advisors, etc., knew the names of the series and the management requirements of each. Such plans are known as programmatic HCPs and are often county- or even region-wide.

Igbadun etal. No Aguilar-Rivera, Armn Trujillo-Mata, in Bioethanol Production from Food Crops, 2019. The weight of each parameter was calculated using an 88 pairwise comparison matrix. The eutrophic series are relatively poorly weathered and require different soil fertility management approaches. 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. Copyright: 2020 Girma R, et al. The process of land suitability classification is the appraisal and grouping of specific areas of land in terms of their suitability for defined uses. /Contents 87 0 R Weldeabzgi GG, Ketema T, Gashu G, Deressa S (2021) Land suitability evaluation for surface irrigation development using parametric evaluation approach: The case of Gudina Wacho watershed, Western Ethiopia. Classification of sandy series according to sand grade has very large practical significance. Chapter 7 describes the economic evaluation of land suitability for irrigated agriculture. Factors considered included physical land features (land use/land cover, soil and slope), and proximity to water sources. Link: Gee GW, Bauder JW (1986) Particle Size Analysis. The criteria used for series differentiation were selected to reflect practical differences related to land suitability and soil management between series. 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). Factors to consider.

The distances were Changes in water quality are not consistent throughout the subarea. 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. Visual interpretation of satellite images was made by using ERDAS IMAGINE and ArcGIS software package for satellite image processing and LU/LC analysis. DTU 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. The limiting factors were soil texture, slop and drainage. In contrast, coarse sandy series have very low water storage capacities per unit soil depth (Laker, 2021). Kiobia etal. Hydrology 8: 86-95. 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. In addition to river proximity, electrical conductivity (EC) of the river water was included as an information. Swati Singh, Shivani Singh, in Visualization Techniques for Climate Change with Machine Learning and Artificial Intelligence, 2023. 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). Fue etal. (2014) were able to quantify the maize production variability due to climate change at the farm level, which is crucial for precision decision support to maize production using decision support system for agrotechnology transfer (DSSAT). Within each of these forms, series were differentiated according to (i) base saturation and (ii) texture parameters, both determined in the B21 horizon (the term used in that publication), i.e., in the upper subsoil. In consideration to river proximity, almost 4% of the river basin is not suited for surface irrigation therefore looking for other sources of water in the nearby is recommended.

The National Association of REALTORS reports that homeowners spent an average of $2453 in 2015 to install irrigation sprinklers. The intensity of importance and their explanation is given in table 3. 0000023133 00000 n Laker (2003) attributed this to: Its emphasis mainly on morphological features, making it easy to identify and classify soils; The fact that only a few simple routine laboratory analyses are required. DET KGL BIBLiOTEK The data are currently for studying purposes only. They, for example, respond well to even low P fertilizer applications, especially the sandy ones, and care must be taken not to over-fertilize them with P (Laker, 2004b, 2021; Nortj and Laker, 2021). Good drainage of the site is essential to allow the continuous movement of water and salt through the profile [14]. Third, for each area of land suitable for direct cultivation of food crops (LOij), the maximum HDPj from cultivation of food crops need to be determined by combining information about crop yield per ha for each suitable crop, with its protein content, and human digestibility. 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). In the application of the AHP method it is important that the weights derived from a pairwise comparison matrix are consistent. Link: FAO (1985) Guidelines: Land Evaluation for Irrigated agriculture. For this study, physical soil factors (soil type, soil drainage, soil depth, and texture classes) are considered as the primary soil factors. JCU Discovery Excluding the national parks, 71% (7% is S1 and 64% is S2) is suitable for the intended use. HCPs can also include conservation measures for vulnerable plant and animal species that are not listed federally as endangered or threatened. Computer Comput Technol Agric 365: 314-325. Guido Fastellini, Eiji Morimoto, in Agricultural Internet of Things and Decision Support for Precision Smart Farming, 2020. To get the weights of the individual criteria, the mean of each row of this second matrix was determined.

Groundwater is a viable option for supplementing surface water resources for irrigation in several basins in the country. The study result could assist policy makers for better decisions during the development of irrigation projects in Omo-Gibe river basin. After classified the whole watershed like that each land mapping unite (LMU) was grouped as flat (LMU-4), gentle (LMU-1&2,) and moderately steep (LMU-3) (Table 5). Part: III. These were classified as follows: These have practical significance. Evaluation of yield and identifying potential regions for saffron (, McPhail Tree Farm, South Carolina, United States of America, There are no unusual constraints on forest management for this property. . Further assessment of the threat type and its potential extent is strongly recommended in order to decide the conditions of landspreading or the design and implementation of improvement/remediation actions. A large proportion of this land, however, was previously covered by forests and to reach biodiversity conservation targets it is probable that grazing would need to cease in some places. These texture differentiations have important practical significance, for example in regard to the plant-available water content of soils. stream Texture parameters consisted of clay percentage classes and for sandy soils also sand grade classes (MacVicar et al., 1977). Maize is the main staple food in sub-Saharan Africa. 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). What education and other capacity-building activities can be given to small farmers to help them better know the players, rules and relationships within new commercialized food systems? 0000021489 00000 n 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. 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]. Their correct identification and management are thus very important in ensuring the country's food security. 0000131532 00000 n 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) illustrates the importance of accounting for feed-food competition. Changes in water quality are not consistent throughout the subarea. (2014) describe how the greedy and informed traders or intermediaries can manipulate the local markets in the villages and hence seek more profit from the rural farmers. The purpose of weighting in land suitability analysis is to determine the importance of each factor relative to other factors. Not all biomass from grasslands can be considered free, without or with merely low opportunity costs for livestock production. The economic value, however, does not represent the suitability of a product for human consumption.

It is often simply stated that sandy soils have low plant-available water capacities. Feed produced on land suitable for human food production, therefore, may result in competition for land between feed and food. 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. Moreover, there was no significant difference in ECe values. Chapter 5 describes procedures for making a land resources inventory. Food security will be sustainable if models to predict and monitor food supply are placed to work and perform well. The system helps the farmer to solve their real-world problems. In other words, the opportunity costs of land for human food production are not considered (Van Zanten et al., 2016). 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). A reminder that in the latter these are 018% (15%), 1835% and >55%, with some change at 60% (55%). 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.
