At the request of the Social and Economic Policy Analysis Unit, a three-day workshop on hydrological modelling using the Water Evaluation and Planning System (WEAP) was held in La Paz from 11 to 13 April. The workshop was organized by UNDESA, UNDP and the Social and Economic Policy Analysis Unit, and co-facilitated by a UNDP consultant along with two specialists from the Ministry of Environment and Water. Ten officials from the Social and Economic Policy Analysis Unit and the National Load Dispatch Committee, who are part of the interinstitutional team of government officials being trained in integrated tools, attended the workshop.
Integrated water resource management concepts were introduced, complemented with hands-on exercises and model exploration. Participants became familiar with WEAP's interface and functionalities, and with Bolivia's Surface Water Balance model (BHSB) in WEAP, its components, methodology and main results. The BHSB was developed by the Ministry of Environment and Water in collaboration with the Stockholm Environment Institute. It is the main input for water balance data used in the CLEWs model for Bolivia.
