TAHMO

News

Every year on the 3rd March the world commemorates World Wildlife Day. We celebrate the wide diversity of animals and plants across the globe while raising awareness about threats facing them.

This year’s theme, “Life below water: for people and plant” is inspired by goal 14of UN sustainable goals which aims to conserve the oceans while also sustainably extracting resources from within them. TAHMO is one of many initiatives contributing to wildlife and water agenda.

TAHMO has installed 10 stations within 22 km of Kenyan coastline, and distributed along the entire coastline. In all national parks, you will find a TAHMO weather station with close range.  Shimba HillsNational park hosts one of many TAHMO stations in Kenya. There are 9 stations close to Maasai Mara national park, 11 stations circling Mount Kenya national park, 5stations near Aberdare national park, 2 stations near Chyulu national park and the list continues. Initiatives like Maasai Mara citizen observatory and TWIGA, which TAHMO is part of, will contribute to the sustainability of wildlife.

Vulnerability to Blue Tick will likely increase in the coming years in Laikipia County in Kenya unless stakeholders intervene. This is according to Peter Mbugua, a Geospatial Information Science and Remote Sensing student at Dedan Kimathi University in Nyeri, Kenya.

Influences of climate changes in the spatial and temporal variation of tick-borne diseases (TBD) are frequently overlooked by researchers. Consequently, there are no effective control strategies and measures to minimize the spread of TBD’s. This results in the loss of livestock, lower productivity, decrease in human health and reduced income from (agro)tourism.

Peter has identified areas in Kenya for low, middle and high risk of TBD. Through using GIS-based Multi-criteria evaluation – including humidity, rainfall, temperature, wetlands, rivers, and slope of the county – Peter determined that the changing trends in weather patterns in the last 15 years continues to favors parasite survival. 

These results can be used to implement measures to counter the spread. For example, high-risk areas can be sprayed and pastoralists can be informed about farm &-livestock management to prevent the spread of tick-borne diseases.

Commissioning of the ATMOS 41 Automatic Weather Station of TAHMO.
Commissioning of the ATMOS 41 Automatic Weather Station

To keep pace with advancement in sensor design and technology on weather related issues, the Vice-Chancellor of the Federal University of Technology, Akure, Professor Joseph Fuwape has commissioned a newly installed 4th Generation ATMOS 41 Automatic Weather Station (AWS) at the WASCAL Centre, FUTA. This is an upgrade of the 1st Generation Trans-African Hydro-Meteorological Observatory (TAHMO) Automatic Weather Station (AWS) which was installed at the WASCAL Meteorological Observatory at the Federal University of Technology, Akure in 2014 as the first TAHMO Station in Nigeria.

The idea of TAHMO started back in 2010/2011 and was formalized through a foundation in 2014. Since 2014 the organization managed to install over 400+ weather stations across 20 African countries. An amazing achievement. However, this did not go as simple as an ABC. Through this blog we would like to lift the curtain on some of the challenges that we faced throughout the years. Perhaps you – our reader – are able to come up with suggestion or ideas to smoothen the challenges that we face up ahead.

So here come the six challenges that TAHMO faces.

Administrative challenges

Have a partnership agreement with national metrological agencies. Every country has a different administrative structure. Countries differ in the way they do business and set up collaboration programs. How do you share data? Who gets it first? How do you share costs and revenues? Who does the maintenance? All these questions need to be answered before you can operate in the area of a governmental agency.

Find an experienced local host who is available in the case of station maintenance. The training that one has to give a local host depends on the various factors. Like is the host staying in the area for the long term? We create a shared responsibility by providing the local host with access to the weather data. This is how the school2school platform was set up. This resulted that most of the local hosts are teachers. Consequently, with 400+ weather stations, this means that a lot of hosts are needed which puts the strain on good & quality relationship management with each host.

Economic challenges

Weather stations are not free. Funding is needed to buy the stations and put them in the right location. We have to pay for the installation and maintenance of each station. Now, here is a little eye-opener: the larger your infrastructure, the more money you have to pay for your maintenance. And maintenance is not always easy. Some weather stations might be right around the corner. But sometimes you must drive up a full day for a quick fix. And although our weather station is the most robust weather stations out there, that does not guarantee a maintenance-free infrastructure. Leaves can get into the funnel, sensors might stop working, or perhaps a tree has overgrown near our weather station, influencing the data.

Equipment challenges

Everywhere we go, we find a different setting with different conditions. The access to the site might be bad, there are safety concerns of theft of our weather stations and more. Sensors might stop working, a hardware update might deplete the batteries and if the station is not regularly cleaned, it will influence the data and even might stop working. For this reason, we promote the cleaning of our stations through our social media. To create awareness that infrastructure should be regularly maintained.

Data Sharing Challenges

The TAHMO weather stations collect data. But with big data, comes great responsibility. With whom do we share this data? What do our partners want to do with it? Should we give it to other governmental institutions like housing or military? Could our data be used to harm people or minorities? These questions are of major importance which have – most of the time – no clear answers. 

Setting up the infrastructure has not been easy. But with the help of our partners, researchers, enthusiast, volunteers, and our great team, we’ve managed to install 400+ weather stations in 20 countries. A great success.

TAHMO places their weather stations at schools so the instruments and data can be used in the classroom. The goal for this is to enhance the climate change curricula. Our TAHMO Field Engineer Kwame Duah went to the Accra Girls Senior High School in Accra to train them in using the weather station. These sessions are great fun. Students are eager to learn about ” what that weather station in their school playground does” and how it can be used in climate change. Here we show 4 different steps on how students learn about climate change through TAHMO. 

TAHMO explained in the classroom

First is a session on how the teachers and students perceive climate change and how it affect their lives. Students explain how irregularity in rainfall makes it difficult for the farm management on their family farm. Teacher tell how it was 20, 30 or even 40 years ago which is a great example of how our climate has evolved in such a short time period. This session creates a direct involvement of everyone in the class. It excites both students, teachers, as well as the TAHMO representative.  

Second, we go outside, stretch the legs! After discussing it, we are going to see it. Students are brought within the enclosure of the weather station to see it up close. It is explained how the surroundings of the weather station are of great influence. We should not have trees to grow next to it or to allow trucks to park in the vicinity to the weather station since it will affect the data. 

Third, we open the weather station. Every little detail and every sensor is thoroughly discussed. What does it do? How does the sensor work? Students can touch and feel it. It is shown how important maintenance is. That it should be checked every month to see if there are no leaves or insects in it.

TAHMO shown to the classroom.

Fourth, we bring out a laptop and show the students how they can log in and access the data. What they can do with it and how it is used by researchers all over the world. This illustrates the importance of everything we did before. How good maintenance provides accurate data, how the environment affects the weather station, and how the data can be used for the farmers to improve their yield. 

Are you a student, teacher or involved in any other way with a school anywhere in the world. And you want to join the TAHMO school2school program? Then be sure to contact us through info@tahmo.org.

TWIGA partners together in Ghana for the TWIGA days
TWIGA partners together in Ghana!

The first week of the TWIGA days consisted of meetings, workshops, and conferences. The first day (Monday) consisted of updates from all the TWIGA partners about the progress made in the previous period. All updates about the projects that have been completed and are still in the developing stage and problems that have occurred have been included.

The Tuesday consisted mostly of workshops. Here, the TWIGA partners split up into three groups; biosphere; hydrosphere and atmosphere. In these workgroups, the partners discussed various new services that could be developed. They made a feasibility and cost analysis and then chose one of the possible services to discuss further.

Develop business models for TWIGA services.
TU Delft students chair a meeting to develop business models for TWIGA services. 

The resulting services which were derived from this workshop are:

  1. Improved insurance for farmers with weather data
  2. Advice for potatoes and cocoa spray
  3. Solar power generation
  4. Early warning system for flooding

The students will focus their internship on the development of these business models for these services in the upcoming months. 

On Wednesday the group participated in a user needs assessment workshop with local farmer-& agribusiness representatives. For this workshop, the team split up again and gave advice about how a user needs can be identified with the Business Model Development method. This workshop was held to identify the farmer’s needs and the agribusinesses needs, with these needs, the corresponding services that TWIGA could deliver were identified. The user needs assessment revealed that services are required, but that facilitating these services is very expensive and might not provide the desired result that the farmers would want. Also, the needs of farmers and agribusinesses match quite well, both would benefit from a lot of services. Interesting was that the users mentioned that they need education and capacity building in farm management knowledge. For example, it is greatly beneficial if a user knows when and how much fertilizers or pesticides needs to be applied. This need can go hand-in-hand with the weather services that TWIGA provides. Since the leaching of fertilizers or pesticides correlates with the weather.

Visiting farmers, weather stations and flooded areas in and around Kumasi

On Thursday the TWIGA partners stretched their legs on a field trip. The weather station was right on the campus of KNUST (Kumasi University). Continuing to the next weather station at a palm oil plantation where a soil moisture sensors were included. 

After these visits were made, all the partners visited a flood site, a bridge over a river in the neighborhood of Aboabo, were many floods take place on a yearly basis. In this situation, the risks and health hazards of floods could also be identified. The floods and blocked drains in the neighborhood made many houses be filled with water on the bottom, like in the picture below. This has made numerous houses uninhabitable and the stagnating water in the area becomes a breeding spot for mosquitos and vector-borne diseases. 

Flooding affected a local mosque in Kumasi.

Lastly,  the group visited a farm, to inspect it for possible placement of a soil moisture sensor (a cable covering the entire field). This sensor can measure which parts of the farmland are in need of moisture of fertilizers, aiding in the efficiency of farming. A great additional benefit to the TWIGA services.

All in all, the TWIGA days illustrated the great need there is for weather services. Looking forward to the next partner meeting!

The TWIGA Kumasi Hardware Hackathon

**Written by Nick van de Giesen
TAHMO has been working with the TWIGA project since the start of 2018. An important output of the TWIGA project will be new geo-services (twenty!) based on the application of innovative sensors. In order to speed up the development of these services, a Hackathon was organized from 19 through 23 November 2018 at the Kwame Nkrumah University of Science and Technology in Kumasi Ghana. The objective was to build complete value chains, from observation to internet storage to service delivery. We aimed high on purpose to see what can and cannot be done in such a short time. The results are very promising! Continue reading on the TWIGA website…

Today, more African universities are taking active roles in the weather industry than before. In the past 2 years, TAHMO East Africa has established relations with 7 leading Kenyan universities, 4 Rwanda universities and a handful of Uganda and Tanzania universities. The activities in the last month point to a growing trend where universities are seeking more pro-active roles in the weather industry.

Mid-November this year, Maasai Mara University in Kenya hosted a workshop on citizen science. Researchers, students, local community and stakeholders co-designed and validated weather solutions for Mara region. Young students are involved in various aspects of research, including co-designing of the apps and mapping baseline data.

Early December this year, the University of Rwanda in Musanze, hosted a weather workshop for its staff and students. Also participating were representatives from 3 nearby universities. TAHMO and Severe Weather Consult facilitated the workshop. 

But why do we have a surge of interest in the weather industry? Here are 3 reasons why universities have an interest in this sector. 

  1. Research:  The primary component for any research is data. Weather data is one variable component. A university will want to be in a position where they tap this valuable asset. 
  2. Dynamic industry: There is a lot of technological changes in the weather industry than before.  The industry has evolved from the conventional meteorological industry to now capturing interests of fields like Engineering, computing, education among others. You could think of this as new ways of measurement, or management of data, generating predictions and disseminating information. The whole industry is evolving rapidly, and there are limitless roles that anyone can contribute in this space.   

  3. Partnership: Because of the many functions and players in the weather industry, universities are seeking ways through which they can complement and share their roles.  

Are you working at an university and curious about working with TAHMO’s weather data? Then contact us through info@tahmo.org and we will be sure to make weather data available at your university.
