With rising coverage figures and the advent of the Sustainable Development Goals, there is increasing attention given to assessing and monitoring the sustainability of water services. Previous efforts in the rural water supply sector have included the development of sustainability checks, while in the urban water supply sector, benchmarking of water services and the performance of utilities has become common practice. This paper argues that neither rural sustainability checks, nor urban benchmarking frameworks, are entirely suitable for monitoring small town water services. It presents a framework specifically developed and applied for assessing and monitoring small town water services. Application of the framework in seven small towns in Ethiopia shows significant discrepancies between the ideal and actual situations. It reveals specific challenges related to sustainable small town water service provision, including capacity at service provider (utility) level, asset management and regulation. The costs of sustainability checks and prospects for uptake as project and wider sector tools are discussed.

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.
