For decades, agriculture is the largest fresh water consumer in Tiquipaya, Bolivia. The ‘remainder’ has been allocated to the city for domestic purposes. This allocation limits in the current situation the city’s development and is gradually resulting in high pressure on the available water sources. This research explores whether it is possible to increase the water productivity in agriculture, without affecting the yields. The objective is to save water that potentially could serve other purposes. Between October and December in 2006, three farmers have been intensively monitored. Each farmer represents the upper-, middle- or lower section of the irrigation system. Unfortunately it was not possible to obtain all the data required for a WP assessment for the farmer in the upper-section. Nevertheless from the analysis it became clear that none of the farmer experienced sever water stress situations, which did not result in a production limitation. However, still a lot of water can be saved by improving the water user efficiency (WUE). Farmers do not seem to distinguish any importance among cultivations and just divided water equally among parcel surfaces. With a different strategy a lot if water could be saved. For example, a water division based on soil depletion and ground coverage.
