The downstream area of Renggung Watershed is a water conservation zone which is also dominated by rainfed land with dominant vertisol soil-clay fraction. Watershed downstream reaches 40% and is 30% of total area of Renggung Watershed. Rainfed farming is a factor in dry land farming, but the presence of rainfed land in downstream Renggung watershed does not receive intensification treatment as water becomes a limiting factor for plant growth. About 87-90% rainfall events in downstream Renggung watershed happen during the rainy season, from November to April, with 3-4 wet months, while about 10-13% happen during the dry season, from May to October. This means that water is abundant in wet months, but there is a shortage of water during the dry period. Based on zone group, 72% of potential water from rainfall occurs in the downstream zone, 18.3% occurs in the middle zone, and 10.4% in the upstream zone. Three quarters of potential water from rainfall occurs in downstream. Water management on rainfed land in downstream Renggung watershed is still not optimum, which is caused by (a) dependence on supply of water downstream from HLD BR, but discharge has declines in the last six months; (b) poor water management at the farming level, because plants are not cultivated in the right season; and (c) poor management institutions and water user groups, so forums to facilitate and mediate issues in terms of management and use of irrigation water is not optimal.

Erosion is of great concern in the Ethiopian highlands. The objective of this study was to determine the soil erosion rates under actual farming conditions by measuring the dimensions and number of rills in 15 agricultural fields in the Debre Mewi watershed near Lake Tana, and to understand farmers’ attitudes towards land conservation through personal interviews with one-third of the watershed households. The annual rill erosion rate was 8 to 32 t ha-1. Greatest rates of erosion occurred at planting early in the season but became negligible in August. Major factors influencing land conservation decisions were the demand of labor and lack of technical support for implementing new conservation measures from experts.
