Exploring Farmers’ Perception and Constraints on the Adoption of Small‐Scale Irrigation in Hulet Eju Enesie District, North‐Western Ethiopia

“…Furthermore, the key informant interview participants also assured that irrigation reduced the fertility of their farming land, and as a result, the output obtained from that land was low during the rainfed production season. The result of this study is consistent with the empirical study by [55]. This indicates that, despiteits positive role, irrigation can cause to soil fertility deterioration through water logging and increases soil acidification, which causes declining production and productivity.…”

“…However, some farmers list increasing land degradation, reducing soil fertility, increasing water contamination, and reducing grazing land as the negative impacts of irrigation on the environment. This result is similar to the finding that, in addition to its positive effect, irrigation enhances the soil salinity of farming land [55]. Figure 4 indicates the overall RII score on a graphical display for negative attributes of SSI.…”

“…Moreover, poor water distribution systems and inappropriate use of water resources were common problems in SSI practices in the study area. This result is likely with the result reported by Eshete et al [29] and Yohannes et al [55] that found a shortage of water, caused a decline in the production and productivity of irrigated crops. This implies that, the application of SSI consumes huge amount of water that emerges from the various sources, thus improving the efficiency of water utilization and management are the main concerns of the country to boost irrigation agriculture.…”

Determination of Optimum Irrigation Scheduling for Onion (Allium Cepa L.) at Bena Tsemay District, Southern Ethiopia

“…According to several reports, Ethiopia is currently planning to use its water resources to cultivate, develop, and irrigate numerous hectares of land in low-lying regions of the nation to combat poverty and provide food security. Furthermore, to solve the problem of water scarcity and achieve food self-sufficiency, the Ethiopian government has given priority to agricultural growth through the promotion of small-scale irrigation (Yohannes, 2020). In Ethiopia's semi-arid and desert regions, the primary obstacles to agricultural growth include inadequate infrastructure and market institutions, a scarcity of technology and inputs, and a high degree of rainfall variability (Bekabil, 2014).…”
