Kisumu turns to GIS in heightened El Niño preparedness

Kisumu, Kenya is turning to Geographic Information System (GIS) technology to bolster the county's readiness for the impending El Niño rains. This move aims to enhance prediction, monitoring, and response capabilities in the face of potential flooding. The GIS system will provide real-time data on flood-prone zones, guiding emergency responders in their efforts.

Kisumu's City Manager, Abala Wanga, highlights that the county is adopting a three-pronged approach to enhance preparedness. These include engaging households, communities, and the national government. GIS plays a pivotal role in identifying vulnerable areas and facilitating early warning systems. The risk mapping exercise has pinpointed several regions within Kisumu City, including Nyamasaria, Dunga, Namthoya, and parts of the Central Business District, among others, as being particularly susceptible to flooding.

To ensure the system remains relevant, the county is in the process of making it more responsive by integrating it with the Emergency Operations Centre. This centre is responsible for coordinating emergency responses and identifying potential risks. Real-time data collection via sensors will enable the county to monitor changing conditions and determine the affected areas.

The GIS system does not merely stop at data collection. Kisumu is also ramping up its emergency response capacity, positioning ambulances, boats, and other essential facilities for rapid rescue operations. The emergency response unit is being reinforced to function 24/7. The GIS system equips emergency teams with vital geographical information, enabling them to efficiently allocate resources during flooding events.

Public health is another critical aspect of flood preparedness in Kisumu. The Emergency Operations Centre collaborates with the Department of Health to monitor sanitation and safety concerns in flood-affected areas. Flooding can exacerbate sanitation issues, especially in regions without sewer systems, thereby posing disease risks. By integrating health and sanitation considerations into the response system, Kisumu aims to address both immediate and secondary threats stemming from flooding.

The data generated by the GIS mapping will also inform physical flood-mitigation projects, such as improving drainage channels and expanding the Nyamasaria River. The latter project, which is supported by World Bank funding, aims to enhance the river's capacity to handle excess water. A GIZ study has been instrumental in informing these proposed improvements.

Given the potential scale of the risk, with an estimated 150,000 to 200,000 residents in vulnerable areas, accurate and timely information becomes crucial. The GIS system aids in locating vulnerable populations, thus aiding decisions on evacuation, emergency response, and the distribution of essential supplies. The Emergency Operations Centre and GIS system are supported by GIZ, UNDP, and the County Government of Kisumu, underscoring the multi-agency effort in this preparedness initiative.
