The objective of this study was to analyze rainfall variability and its impact on rice production in the Fogera Plain. The analysis used historical rainfall and yield data from four stations. Historical daily rainfall and yield data were obtained from the National Meteorology Agency (NMA) and Amhara Regional State Bureau of Agriculture, respectively. The rainfall data were subjected to trend and variability analysis. Partial correlation and multiple regression analyses were used to determine the relationship and impact of rainfall characteristics on rice yield. Results showed a decreasing trend of rainfall amount, shortening of the length of the growing period (LGP), increased the variability of rainfall onset date and dry spell length in the study area. The analysis revealed that dry spell lengths of 5 days (sp5), 7 days (sp7), 10 days (sp10) and 15 days (sp15) varied over the study areas with dry spells getting more prevalent in Woreta and Maksegnit compared to Bahir Dar and Gondar stations. Rice yield was positively and significantly correlated with annual rainfall amount (0.69**), LGP (0.61**), and a number of rainy days (0.59*). On the other hand, rice yield was negatively and significantly correlated with rainfall onset date (-0.693**) and length of a dry spell (-0.62**). Rainfall parameters explained 69% of the rice yield variability. The study indicated the need for managing rainfall variability to increase the productivity of rice in the Fogera Plain.

Irrigation enhances resilience to the negative impacts of climate change through sustainable food production and environmental health. However, water is a scarce resource that needs efficient utilization. This study explored (1) farmers’ perceptions about the roles of irrigation in climate change adaptation and (2) determinants of the choices to selected WUE-improving soil and water management practices in southern Ethiopia. A multistage sampling technique was used to survey 373 households. The results indicated that the majority of surveyed households were male-headed: 90.6%, above 40 years old: 56.8%, and uneducated: 73.5%. They perceived that irrigation improved their net income (INCOM): 88%, acted as insurance against decreased rainfall (IADR): 44.8%, and insurance against increased temperature (IAIT): 70%; though the water was not available in all dry seasons: 55%. The choice to tightly close water-diversion points after use is significantly positively (p < .05) affected by education level (EDUC) and perceptions about irrigation water as IADR and IAIT. However, the farmers’ perceptions about INCOM significantly negatively affected their choice to not irrigate at peak sunshine hours. The choice of mulching is significantly positively affected by the perception of INCOM and IAIT. Similarly, the choice of using compost is significantly positively affected by EDUC and their perceptions of IADR and IAIT, and significantly negatively affected by INCOM. The choice of not practicing conventional tillage is strongly negatively affected by the farmers’ perceptions about equitable water distribution (EWD) and INCOM. Therefore, it can be concluded that the farmers’ understanding of the roles of irrigation in climate change adaptation is good but their understanding of WUE-improving practices is poor due to poor water distribution systems and low education levels. So, improving water distribution systems and farmers’ awareness about WUE-improving practices are suggested to the study area and other countries under related conditions.
