Different research outputs of SATIDA are currently advanced in collaboration with different humanitarian aid organizations and the International Research Institute for Climate and Society (IRI) at Columbia University in New York.
We’ll keep you updated. Stay tuned.
You’ll find the publications related to the SATIDA project here:
– A Combined Satellite-Derived Drought Indicator to Support Humanitarian Aid Organizations (Remote Sensing)
Food Security Monitoring via Mobile Data Collection and Remote Sensing: Results from the Central African Republic (PLOS ONE)
Combining satellite observations to develop a global soil moisture product for near real-time applications (Hydrology and Earth Systems Sciences)
We recently completed the deliverables about:
Two more deliverables about the field test and the forecasting component are on their way.
We just uploaded the first file to Outernet. Also the hardware is ready. Ideally, we’ll be able to receive this file via Outernet’s lighthouse this week.
We just received a Lighthouse (receiver) from Outernet. Updating the firmware via MicroSD was easy. Now we just need a satellite dish and a koax cable to run the first test. If the test is successful we’ll be able to deliver information about drought conditions to virtually any place on earth, independent from any network.
Supported by the Spanish Section of Doctors without Borders, we tested our mobile app “SATIDA COLLECT”. The collaboration with local community health workers worked fine. They were trained for one day and finally managed to visit more than 100 households, representing more than 900 family members. All assessments were uploaded to a database that also allows visualizing the GPS location of each dwelling. Despite a very poor bandwidth the upload of one completed assessment took between 5 and 10 seconds. Knowing the current coverage based on the GPS information gives users a good overview of regions that have/have not been covered by surveys.
Our findings indicate that the food insecurity in our region of interest, which will currently not be disclosure on this blog due to its unstable political condition, that was observed last year was not related to a climatic shock, but to the violent conflict. Based on our satellite-derived data we could proof that there was not a significant deficit in rainfall or soil moisture. However, people were afraid of farming due to the presence of armed groups. Finally, we identified several other applications that SATIDA COLLECT could be used for, such as evaluating the success of vaccination campaigns by a quick digitization of the assessments. Out of these preliminary results, a final report/publication is now available here.
The nice guys from a company named Parrot, which produces devices that measure variables such as soil moisture, just agreed to provide us with one of their probes.
They connect to smartphones via Bluetooth, making it possible to validate our satellite-derived measurements of soil moisture on the ground.
The field tests were finally confirmed for 5-21 May 2015.
One of the 100 first Outernet receivers (“Pillars”) will arrive soon. Then we can finally upload the first pieces of info to Outernet! Exciting days!
Difficult security conditions require the postponement of our field test to May 2015.
