Urban flood warning for Dire Dawa, Ethiopia

Early Warning and Anticipatory Actions receive increasing attention recently. Of the many hazards subject of early warning, we note that urban flooding is simultaneously one of the more challenging and impactful issues especially in developing countries and Africa in particular. HKV, Deltares, the Netherlands Red Cross, TAHMO and ICPAC have united to take up this challenge.

 

Rapid urbanization across Africa results in crowded, poorly planned cities. Many of these cities face floods several times a year, usually in lower-income, vulnerable and informal areas. Large damages and loss of lives are common impacts. While flood mitigation measures are expensive and require complex urban planning processes, early warning and early actions can mitigate impacts effectively.  

 

Early warning for urban areas is challenging in multiple ways. Urban floods typically occur within a few hours after severe rainfall and occur suddenly and very locally. This makes them hard to predict, with a need for timely, precise and accurate information. It also provides a challenge in warning dissemination and anticipatory actions, once floods are predicted, to ensure the right actions are taken and people are informed timely and effectively.

 

Our consortium brings together expertise on monitoring and short term forecasting of extreme rainfall in Africa, super-fast flood models and carefully designed warning dissemination and anticipatory action protocols. This is combined into an early warning system for urban floods. Specifically, we will work on research into and the application of: 

  1. Merging satellite-based rainfall estimates and TAHMO sensors for nowcasting to provide

precipitation forecasts for short lead times, 

  1. A coupling between a distributed hydrological model and an innovative rapid flood

inundation model to calculate urban flood impacts at high computational speed, and 

  1. Integration of the rainfall forecast and flood impact model for urban flooding in impact

based forecasting platforms to enable anticipatory action.

With support of the Dutch Partners For Water program, we will pilot this solution in Dire Dawa in Ethiopia. This is a city of almost half a million citizens, which suffered many flood induced casualties over past decades. After this pilot, the concept is ready for application to other urban areas in Africa.

The project is aligned with the Water at the Heart of Climate Action partnership.


TAHMO Attended GSMA MWC Meeting

In October, representatives from TAHMO in Rwanda and Tanzania embarked on a transformative journey to the GSMA MWC Kigali Series. The GSMA, a global organization dedicated to unifying the mobile ecosystem and driving innovation for positive change in both business and society, set the stage for an inspiring gathering.

As a climate and weather observatory institution, TAHMO found itself uniquely positioned to leverage the opportunities presented at this event. The theme of a “new chapter for climate action” resonated deeply with the organization’s mission. However, the real game-changer was TAHMO’s selection by the GSMA Mobile for Development Foundation, Inc. for an Innovation Fund Grant Agreement. This recognition was more than just an accolade; it was a chance to further their noble cause.

The vibrant setting of the KIGALI M Hotel hosted a startup boot camp on the 15th and 16th of October, attended by Lisa from Tanzania. The connections made during this event would prove to be pivotal in the days to come.

On the first day of the meeting, attendees were treated to insights from notable speakers, including the esteemed President of Rwanda, Paul Kagame. His emphasis on “making digital life cheap and inclusive” set the tone for a gathering aimed at breaking barriers and driving positive change.

The second day of the meeting maintained the momentum, focusing on “unleashing tomorrow’s technology today.” Sessions were dedicated to building a connected Africa, with distinguished speakers like Lacine Kone sharing their perspectives and expertise.

The overarching theme of the GSMA MWC Kigali Series was crystal clear: the mobile industry had the potential to be a force for good in the realm of climate action. Climate change is an existential threat that humanity must address, and the mobile industry is poised to play a significant role in this global battle.

The mobile sector has made significant strides by collectively developing an industry-wide climate action roadmap with the ambitious goal of achieving net-zero greenhouse gas emissions by 2050, aligning with the Paris Agreement. The commitment of around 80% of the global mobile industry by revenue to disclose their climate impacts, energy consumption, and GHG emissions through the CDP global disclosure system was a testament to their dedication. Moreover, over 60% of the industry had committed to science-based targets, a pledge to rapidly reduce carbon emissions over the next decade.

The mobile industry’s proactive approach to addressing climate change didn’t go unnoticed. It was recognized as one of the first breakthrough industries, with the GSMA serving as an accelerator for the UN Race to Zero initiative. The Mobile for Development’s ClimateTech program was furthering these efforts, aiming to foster greater integration between digital technology and climate mitigation, adaptation, and resilience strategies, particularly in low and middle-income countries.

TAHMO’s mission aligned seamlessly with these global efforts. The Trans-African Hydro-Meteorological Observatory (TAHMO) was on a mission to develop an extensive network of weather stations across Africa. These stations would provide critical current and historical weather data essential for various applications, including agriculture, climate monitoring, and hydro-meteorology. TAHMO’s presence at the GSMA MWC Kigali Series was a testament to their commitment to harnessing the power of mobile technology for the betterment of Africa and the planet.

In Kigali, a shared vision for climate action, innovation, and a more connected world brought people and organizations together. It was a glimpse into a brighter, more sustainable future where mobile technology played a pivotal role in the fight against climate change. As the event concluded, attendees departed with renewed determination and a sense of purpose, ready to continue their collective journey towards a more sustainable and climate-resilient world.

In September 2018 TAHMO was invited by Winrock International to participate in a workshop in Dakar, Senegal on: ‘‘Sustainable Climate Information Services (CIS): Expanding CIS delivery through innovative financial and business arrangements’’.
After the welcome speeches done by Julia Bradley-Cook (USAID); Filipe Lucio (GFCS Director, WMO); and Robert O’Sullivan (Winrock International) who also gave a brief introduction of the Sustainable CIS project and a review of the agenda.
The workshop was divided into two sessions: A review of metrics to assess the National Meteorological and Hydrological Services (NMHS) capacity and a review of the NMHS financial planning tool. In summary, the workshop allowed the organizers to present both Global Framework for Climate Services (GFCS) metrics:

1. Observations and Monitoring; 2. Research, Modeling, and Prediction; 3. Climate Service Information System; 4. User Interface Platform; and, 5. Capacity Development.) and the WMO NMHS Categories (1. Basic Climate Services; 2. Essential Climate Services; 3. Full Climate Services; and 4. Advanced Climate) Services. These two schemas were combined by WMO to create a new framework to guide the NMHS enterprise in identifying their needs and finding resources through either donor, private or PPP.

Dr Theophile MANDE, the representative of TAHMO in the workshop contributed to the discussion by sharing TAHMO’s experience in working with NMHSs reporting on both positive elements and challenges.
In terms of challenges four groups could be identified:
Administrative challenges
Having MoU signed with NMHSs (which is sometimes really difficult and it can take several years);
Having NMHSs staff involved in the station installation, monitoring

and

maintenance;
Have experienced localhost (Not enough skills or

overexploited

competences);
Need a lot of

localhost

(at least one per village where we have stations installed).
Economic challenges
Acquire the stations
The cost of the installation and maintenance
Paid field staff (Engineer; Directors; local Host)
Equipment challenges
Local conditions (access to sites; safety etc.)
Sensors breaking; dust and batteries
Software update
Station cleaning (rain gauge)
Data sharing challenges
On this particular challenge, several questions arise: How to share data? With who? Under which conditions (free, sell)?
For TAHMO these data have to be free at least for scientific needs but deep exchanges with NMHSs are necessarily knowing that data production is their first activity and source of income.
Success
TAHMO achieved building strong relationships with several NMHSs with around 25 MoU signed and a network of more than 500 stations installed from which more than 90% are running. The data collected is frequently checked by TAHMO QA/QC team which ensures good quality data. These data are also easily available through the network.
TAHMO’s participation and contribution at the workshop were very much appreciated by the organizer and an appointment was made for the next workshop.
On behalf of TAHMO, Dr. MANDE thanked WINROCK and its partners for inviting TAHMO to this workshop which appears to be very rich and relevant for both NMHS and Private structures such as TAHMO. A details study of these approaches will be done by TAHMO aiming to adapt them to their needs; the representative of TAHMO believes that this tool (if accepted and used by NMHS after validation) will help improve both (administrative and financial) relationships between NMHSs and Private Sectors which will be clear and win-win.


On March 15, Kenya was put on partial lockdown after 2 COVID cases were reported in the country.  Alongside the government-imposed dusk-to-dawn curfew, schools were closed and movement restricted. Within a week, the lockdown wave had spread to most East African countries. It created a sense of panic, fear and uncertainty. This hit our team hard because our work involves traveling, meetings and working with schools. I wondered how we would carry on with field activities.

At TAHMO East Africa, we have an elaborate guideline for field work that ensures we provide high-quality data. If a weather station is faulty for instance, our first point of contact is the host who checks if the issue is minor and where possible resolves the issue. But if the issue is more complicated, one of our technicians/meteorologists/engineers visits the site. Additionally, we have put up structures for preventing station failures. One way is by yearly preventive maintenance where we visit all the stations to identify any potential future problems and resolve them beforehand.

When lockdown came along, we were at the peak of our yearly stations maintenance. I also had scheduled travels, clients to meet, projects to initiate and projects to push forward. All this put me in a limbo. Top on my list of attention was how our team would carry along repairs. There are no two ways with weather stations. If it is not working, data not captured will never be recovered. But how then would we carry on with the activities with COVID challenges?

In Kenya, most stations are hosted in schools. When schools shut a big number of teachers relocated. We did not have effective communication with the hosts anymore. Traveling to the sites was a challenge too. You would be comforted with several fears – caught out of time due to delays in screenings mounted in roadblocks, or at worst, being put on government quarantine.

By mid-April, we had put up a structure where more people would help with field activities. In Kenya for instance Victor (TAHMO Engineer) involved former interns and volunteers living in areas where we could not travel to assist with some of the work. In Rwanda, Honore (TAHMO Engineer), trained new technicians via zoom that would take work in areas in regions he was unable to travel.

At the time of this writing (mid-July 2020) countries are easing restrictions. There is less fear – we have probably learned to carry on with our work amidst the challenges. TAHMO East Africa Network improved tremendously in the last two months. Not everything is working right, and we do not expect everything to be smooth soon. There is still a sense of uncertainty about how the future will look after COVID.  But we will keep the hope and develop more ways of keeping our work going.


With climate change increasing its mark on all aspects of the hydrological cycle, societies all over the world living in flood-prone areas are increasingly exposed to flood hazards. In many parts of the world,
especially in less developed areas, societies lack knowledge and data to predict future flood events.

By predicting a future flood event, an organization creates a time frame to implement a mitigating action that reduces the financial damage inflicted. In recent years, the development of new measuring techniques has significantly lowered the cost of collecting data and information on different aspects of the hydrological cycle.

These developments enable organizations in regions restrained of knowledge and data to establish methods to analyze aspects of the hydrological cycle, thereby predicting the probability of a flood hazard several hours or days in advance. This thesis explores various possibilities for designing and implementing an Early Warning System (EWS) for the Bus Rapid Transport System (BRT) in Dar es Salaam.

The EWS design is based on the forecasting requirements, investigated with the BRT-system. Several operational forecasting methods are available. The EWS designed in this thesis makes use of rainfall data obtained from rainfall stations located in the Dar es Salaam region, installed and managed by the Trans-African Hydro-Meteorological Observatory (TAHMO).MoreFinal_Thesis_Markus_Pleij_4238001
