How mobile phones are improving irrigation in Niger
Issued on: Modified:
An entrepreneur from Niger has created an irrigation system that allows farmers to control the watering of their crops from afar by simply using their cell phones. The system uses water more effectively and pollutes less than methods traditionally used by local farmers for irrigation.
Abdou Maman Kané is the man behind this “remote irrigation system”. He’s been selling the system in Niger since 2013, through his business Tech-Innov. About 200 farms – both individual and collective – currently use the system.

"The remote irrigation system allows farmers to irrigate larger surface areas"
I dreamed up this irrigation system because the way that we currently irrigate our crops in Niger is not effective.
Firstly, it’s estimated that farmers in Niger spend two-thirds of their working time just watering because most don’t have machines to irrigate their crops.
Secondly, farmers can lose up to 50% to 60% of water before it reaches the crops just through leaky buckets and pipes. Water is often lost if it is channeled through canals to reach the crops because the ground absorbs a large percentage of the water before it reaches the fields.
Finally, most of the water used for irrigating crops is pumped up from underground sources. The fuel used to operate these pumps is expensive and also pollutes.
Moreover, these pumps have to be started and stopped manually-- even if they are 70 metres down. This is a very dangerous process and people die doing it. Often, workers are lowered down with a rope and some people have fallen to their deaths. Others die after inhaling poisonous gases released by the underground water tables.
"We use solar power to fuel the pump"
Our remote irrigation system involves four different components.
We give farmers a pump, which can be used both above and below ground, depending on where the water is located. For 95% of the installations that we do, the pump is powered by solar panels, which we also install. We make sure to adapt the irrigation system according to which crops the farmer is cultivating. For example, we use a drip system if plants only need to be hydrated through their roots. If the plants also need to have their leaves watered, we alter the system. Finally, we install a box between the pump and the solar panel that contains a SIM card, which makes it possible to control the whole system remotely.
Each time that we install this system, we do a careful study of how much water each plot of land needs.

"All you have to do to start up the irrigation system is dial a number on your cell phone"
Once the entire system is installed, when a farmer wants to irrigate his farm remotely, all he has to do is dial the numbers "142" on his cell phone. That free call connects him with the system.
If he happens to be illiterate -- which is the case for many farmers in Niger -- then the server automatically sends a signal to start up the pump for a set amount of time.
If the farmer does know how to read, then he can indicate how long he wants the pump to run. These calls cost 200 CFA francs [Editor’s note: or 30 euro cents].
The system is controlled remotely using a cell phone.
"We can collect meteorological and hydrologic information in real time"
The “remote irrigation” system also includes an optional component, which collects meteorological and hydrologic information in real time. It records information like the temperature, the humidity percentages in the soil, the levels of solar radiation, wind speed and rainfall -- all for the farmer’s use.

Thanks to this system, farmers use water more effectively and waste less. They can use the saved water to irrigate larger surface areas, thus producing a larger crop yield. Because the pumps are fueled by renewable energy, they pollute less and are cheaper. Because they can irrigate their fields remotely, farmers also lose less time watering their fields. They can spend the time saved on other activities!
"It’s possible to earn back your investment after a year"
The main problem with our system is the price tag, because it still costs a million CFA francs [Editor’s note: equal to 1,524 euros]. Most farmers aren’t able to buy it without help from an NGO or a loan from our partner banks. But it’s possible to earn back your investment after a year. In fact, all of the components of our system are produced in Europe. They’d be cheaper if they were produced locally.
There are about 200 farms – both privately-owned and collective – that use the remote irrigation system in Niger.
