Digital Humanitarians! We need you! – HOT Tasking Manager

Don’t have time to volunteer at your local relief center? Can’t commit to emergency deployment for days, weeks, or months? Do you have access to the internet? Do you have an eye for detail, and the patience of a mantis? If your answer is mostly yes, maybe being a digital humanitarian is just right for you.

A new type of humanitarian is needed in the fast paced world of information technology and global disaster management. The Digital Humanitarian is this new breed of humanitarian actor that provides important all volunteer services to field based agents in areas of digital mapping, and remote sensing technology.

Maps are essential in a rapid deployment humanitarian environment. Identifying passable road networks, or locating damaged infrastructure are just a few of the important outcomes that digital maps provide humanitarian relief agents and disaster managers need.


Through Open Street Map, the opensource and community led mapping platform, people with access to the internet and basic knowledge of digital tracing can be valuable contributors in creating map data from free satellite imagery or from other aerial imagery sources. The Humanitarian OpenStreetMap Team or HOT as it is known by relief and disaster risk reduction agencies; is led by volunteer contributors known as “Activators”. These activators specialize in a variety of fields and could be your neighbors that are capable of mapping kilometers of road networks and building outlines in another country.

Volunteering in the 21st century has become digital. People can go to http://learnosm.org/en/ to find out more about how to contribute to Open Street Map and eventually volunteer for HOT. In addition to learning about OSM, HOT volunteers should also learn about HOT-OSM activation protocols at http://courses.hotosm.org/ . Learners can earn trainee badges from accomplishing different areas of HOT activation. OSM_Data_Trainee.pngImagery_Trainee.pngValidation_Trainee.pngUsability_Trainee.pngPublic_Relations_Trainee.pngCommunity_Care_Trainee.pngPartner_Liaison_Trainee.pngReporting_Trainee.pngTasking_Trainee.png

If you already have experience in contributing to OSM, head on to http://tasks.hotosm.org/

In lieu of the recent Earthquakes in Ecuador and Japan, there are several “Projects” that you can sign up for to trace buildings, road networks, and other important features assigned by the Project’s lead. Locally, there are many projects led by the Philippine Red Cross and ICRC to map areas in the Philippines for disaster risk reduction management planning. Also, if you want to assist the government in its effort to create more accurate hazard impact assessments, start mapping in this project.

Happy Mapping!!!


The Green Lantern C…err The Climate Reality Leadership Corps

Climate Reality PH logo

In brightest day, in blackest night, no evil shall escape my sight. Let those who worship evil’s might Beware my power–Green Lantern’s light!” – Green Lantern Oath

The Climate Reality Project recently conducted last March 14 to 16 the 31st Climate Reality Leadership Corps Training for at least 400 people from more than 50 countries to become heralds of truth about Climate Change and the Anthropocene influence on burning dirty fossil fuels. I was one of the few who was privileged to attend this event that was presented by leaders and renowned experts in the field of climate science and education. Plus, former U.S. Vice President and Nobel Laureate Al Gore was the main presenter and trainer for three days.

The training would have been a Green Lantern Corps convention less the green rings; if not for everything that can be classified as Green from ensuring that sustainability and waste reduction principles are followed in food and beverages served (vegan meals for three days), energy use, training kits to its noble mission of advocating for climate change reality leaders in a world that is confused or misdirected by organizations that have a high stake of maintaining the status quo in the fossil fuel industry. I am reminded of the Green Lantern Oath for we are in the days that the effects of climate change to weather related phenomena has caused destruction on human settlements and disruptions in the food supply chain. The Philippines is no stranger to these hazards. If there will be no one to take the mantle of communicating the problems that humans have caused to our ecosystem; then it is inevitable that future generations will suffer more than we have experienced to date.  Continue reading “The Green Lantern C…err The Climate Reality Leadership Corps”

Pasig City Hazard Impact Assessment

Pasig City was one of the worst hit areas during Typhoon Ondoy. Using WebSAFE, we can now estimate number of affected population based on 25 year and 100 year flood hazard models. Refer to the image for more information:




WebSafe is an online tool adapted by Project NOAH (Nationwide Operational Assessment of Hazards) from InaSafe, the innovative open source plug-in tool jointly developed by the Indonesian Government, Australian Government, and World Bank.
