“…Fekadu and Negese [47] on the other hand reported that soil pH, AWC, TN, and available P were identifed as the principal limiting factors for wheat and barley crops in Yikalosub watershed, Ethiopia. Another study by Debalke et al [48] identifed soil organic matter, temperature, length of growing season, rainfall, soil depth, and pH to be the primary limiting elements preventing the cultivation of wheat, barley, and tef in the Arsi zone of Ethiopia. Decisions for efective agricultural planning can be benefted more from cropbased land suitability studies for micro land areas, instead of land assessments of macro land areas [46].…”

This study has evaluated suitability of the Sinana Research Site (SRS) (southeastern Ethiopia) for sustainable wheat and barley production to improve local food security. Physical land evaluation was undertaken using data about ten land characteristics. Matching land characteristics with land use requirements was made, first. Decision on the overall level of suitability of the area for wheat and barley farming was conducted using the “maximum limiting factor” technique. Over two-third (70.2%) of SRS was marginally suitable for barley farming, but 29.8% of the area was “not suitable” for it. Only slightly less than three-fifth (57.6%) of the area was marginally suitable for wheat production, and the rest 42.4% was “not suitable” for it. Deficient N and P supply and soil alkalinity were critical constraints of land suitability for both crops. Thus, integrated application of inorganic and organic fertilizers and rotating leguminous crops with wheat and barley are useful to mitigate deficiency of N and P in the soil. Hence, farms under “marginally” and “not” suitable classes could be improved to moderate (S2) or high (S1) level of suitability for the crops studied. This, in turn, improves yield and food security status of households in the study area.

Land suitability analyses are crucial for identifying sustainable areas for agricultural crops and developing appropriate land use strategies. Thus, the present study aims to analyze the current and future land suitability for wheat (Triticum aestivum L.) cultivation in Ethiopia. Twelve variables including soil properties, climate variables, and topographic characteristics were used in the evaluation of land suitability. Statistical methods such as Rotated Empirical Orthogonal Functions (REOF), Coefficient of Variation (CV), correlation, and parametric and non-parametric trend analyses were used to analyze the spatiotemporal variability in current and future climate data and identified significant patterns of variability. For future projections of land suitability and climate, this study employed climate models from the Coupled Model Intercomparison Project Phase 6 (CMIP6) framework, downscaled using regional climate model version 4.7 (RegCM4.7) under two different Shared Socioeconomic Pathway (SSP) climate scenarios: SSP1 (a lower emission scenario) and SSP5 (a higher emission scenario). Under the current condition, during March, April, and May (MAM), 53.4% of the country was suitable for wheat cultivation while 44.4% was not suitable. In 2050, non-suitable areas for wheat cultivation are expected to increase by 1% and 6.9% during MAM under SSP1 and SSP5 climate scenarios, respectively. Our findings highlight that areas currently suitable for wheat may face challenges in the future due to altered temperature and precipitation patterns, potentially leading to shifts in suitable areas or reduced productivity. This study also found that the suitability of land for wheat cultivation was determined by rainfall amount, temperature, soil type, soil pH, soil organic carbon content, soil nitrogen content, and elevation. This research underscores the critical importance of integrating spatiotemporal climate variability with future projections to comprehensively assess wheat suitability. By elucidating the implications of climate change on wheat cultivation, this study lays the groundwork for developing effective adaptation strategies and actionable recommendations to enhance management practices. The findings support the county’s commitment to refining agricultural land use strategies, increasing wheat production through suitability predictions, and advancing self-sufficiency in wheat production. Additionally, these insights can empower Ethiopia’s agricultural extension services to guide farmers in cultivating wheat in areas identified as highly and moderately suitable, thereby bolstering production in a changing climate.
