The ambition of 510 is making humanitarian aid faster, more effective and more personal through the use of big data. 510 million square kilometer is the total surface of the earth.


Community Risk Assessments & Typhoon Nina in the Philippines

The open-source Community Risk Assessment and Prioritization
toolbox collates open data on vulnerability and coping capacity
indicators. Combined with hazard risk data (pre-disaster) or
predicted damage data (post-disaster), this allows us to identify
priority areas for humanitarian intervention much faster.
Recently, the Priority Index prediction model has been tested a
second time on typhoon Nina, one day after it struck the
Philippines. In addition, we have tested the perception of our
model by decision makers and refined its visual design with help
of Development Gateway. Currently, further roll out of the
model to Mali and Zambia is being prepared.

Missing Maps in Malawi

Malawi is a country prone to humanitarian disaster, and
510 is working with the Malawi Red Cross to identify the
country’s most vulnerable areas. A team of twenty Malawi
Red Cross Society (MRCS) volunteers, in cooperation with
510, have developed and successfully tested a new
method to determine vulnerability based on a remoteness
indicator. After a training on the use of digital surveying
tools, volunteers from 510 and the MRCS validated the
remoteness indicator in the remote areas of Malawi’s
Thyolo district. Through this validation, remotely sensed
data has proven to be an efficient and cost-effective
source of analysis for remoteness indicators. The method
now has potential to be applied to vulnerable regions

SIMS Support for Africa Food security crisis

510 continues to assist the IFRC regional office of Africa in response to the ongoing food security crisis in the region. As of April 19th 2017 a team member has been deployed to assist at the IFRC regional office in Nairobi. The delegate’s work is focused on facilitating the flow of information from the field to the regional office and helping the Red Cross National Societies improve their mobile data collection methods. In coming weeks the SIMS support coordination role will be also transferred from the 510 office to Nairobi, to provide more effective support.

Data preparedness in Malawi

In February 2017 three 510 team members joined the Malawi Red Cross in a first of its kind data preparedness mission, consisting of a.o. a data workshop, meetings with key data providers for disaster management and mapping with Red Cross volunteers. In Malawi, we learned about local data preparedness capabilities, increased awareness of its importance and ignited corresponding capability building. This has proven especially important after the 2015 Malawi floods which led to a severe food crisis. Several new projects will start in coming months and the Malawi Red Cross is assessing how they can build up within their organization a structure similar to the one of the 510 team: a unique and powerful mix of data savvy volunteers, professional staff and students.  [Link to blog]

Peer to peer CTP

In the humanitarian aid sector, cash transfer programming (CTP) is increasingly used for providing in-kind assistance to those in need. Also, peer-to-peer CTP is becoming increasingly accessible thanks to recent data-driven & technological innovation. As a result, the Netherlands, British and Irish Red Cross national societies are assessing whether and to what extent peer-to-peer CTP is a viable option in the field of humanitarian aid. At 510 we are researching the Red Cross’ social interface role with beneficiaries in the field, potential for peer-to-peer CTP and cooperation with the private sector.
