Development Problem

During the Consultations and Needs Assessment Workshop conducted in Tanzania in May 2016, water unavailability was identified as one of the major challenges facing the communities in the nine river basins in Tanzania. This problem is being associated with climate change in form of rainfall variability and rising temperatures which in turn leads to receding water levels in reservoirs, rivers, and lakes. The problem is compounded by erratic droughts, resulting in conflicts between competing users. Monitoring water unavailability is worse in basins that do not have river level monitoring stations to allow a continuous monitoring of water in those rivers and effective water resources management measures to be put in place.

Stakeholders in Tanzania

SERVIR E&SA will work with various stakeholders from Tanzania including the Ministry of Water and Irrigation (MoWI), Tanzania Electricity Supply Company (TANESCO), communities in the pilot catchment, Water Users Association, Basin Water Offices (BWO), Zonal Irrigation Office in the catchment, research institutions and urban water supply bodies (pilot catchment).

The problem of flooding has also been flagged as a major issue especially for Kenya and Uganda. For instance, the Nzoia basin in Kenya, L. Kyoga basin in Eastern Uganda and Nyamwamba basin in Kasese area are affected by floods every rainy season. Though there are many on-going initiatives addressing the issue of flooding in Kenya and Uganda, most of them are structural based while others require installation of ground based equipment’s for flood monitoring of which the stakeholders find very expensive to implement. The Ministry of Water and Environment in Uganda requested to be equipped with techniques and methods for processing of satellite data for use in flood monitoring while Kenyan stakeholders, like KMD expressed the need to have the capacity to use satellite information to inform flood issues in Nzoia basin. To address these issues, SERVIR E&SA will work with AST-2 from the University of Oklahoma to implement the Ensemble Framework for Flash Flood Forecasting (EF5) framework for flood monitoring in pilot basins in Kenya and Uganda.

Stakeholders in Kenya and Uganda

Key stakeholders include Kenya Meteorological Department, Water Resources Management Authority (WRMA), and Ministry of Water and Irrigation in Kenya and Ministry of Water and Environment (MWE), Uganda Met Agency (UMA) and Disaster Office in Uganda.

Service Objective

The main objective of the service is to equip the key stakeholders with the skills and capacity to use geospatial data and products developed from the hydrological models in addressing issues on water availability and flood management.
