With crisis mapping’s increasing profile, other organizations have joined the fray. Just this month, Facebook announced that it was partnering with UNICEF, the World Food Programme, and other partners to “share real-time data to help respond after natural disasters,” and the United Nations has also contributed to the field with its Office for the Coordination of Humanitarian Affairs (OCHA) founding MicroMappers along with Meier, as well as creating UNOSAT, the UN Operational Satellite Applications Programme of the United Nations Institute for Training and Research.

In a 2013 interview, UNOSAT Manager Dr. Einar Bjorgo described the work of his office.

“When a disaster strikes, the humanitarian community typically calls on UNOSAT to provide analysis of satellite imagery over the affected area… to have an updated global view of the situation on the ground. How many buildings have been destroyed after an earthquake and what access roads are available for providing emergency relief to the affected population? We get these answers by requiring the satellites to take new pictures and comparing them to pre-disaster imagery held in the archives to assess the situation objectively and efficiently.”

Four years later, UNOSAT’s work seems to have become even more important and has evolved from the early days when the group used mostly freely available imagery and only did maps.

The word “disruption” is frequently used to describe technology’s impact on every facet of human existence, including how people travel, learn, and even speak.

Now a growing cadre of digital humanitarians and technology enthusiasts are applying this disruption to the way humanitarian aid and disaster response are administered and monitored.

Humanitarian, or crisis, mapping refers to the real-time gathering and analysis of data during a crisis. Mapping projects allows people directly affected by humanitarian crises or physically located on the other side of the world to contribute information utilizing ICTs as diverse as mobile and web-based applications, aggregated data from social media, aerial and satellite imagery, and geospatial platforms such as geographic information systems (GIS).

How does political context shape education reforms and their success? Lessons from the Development Progress project
ODI

Achieving Sustainable Development Goal 4 – ‘Ensure inclusive and equitable quality education and promote lifelong learning opportunities for all’ – is one of the most important and challenging tasks in international development. In order to fulfil it, we require a better understanding of why progress and the impact of interventions varies so widely by context. One striking gap in our knowledge here is a lack of analysis as to how education systems interact with political contexts that they operate in. This report addresses this gap by drawing on evidence from eight education-focused country case studies conducted by ODI’s Development Progress project and applying political settlements analysis to explore how political context can shape opportunities and barriers for achieving progress in education access and learning outcomes.

Combining satellite imagery and machine learning to predict poverty
Science

Reliable data on economic livelihoods remain scarce in the developing world, hampering efforts to study these outcomes and to design policies that improve them. Here we demonstrate an accurate, inexpensive, and scalable method for estimating consumption expenditure and asset wealth from high-resolution satellite imagery. Using survey and satellite data from five African countries—Nigeria, Tanzania, Uganda, Malawi, and Rwanda—we show how a convolutional neural network can be trained to identify image features that can explain up to 75% of the variation in local-level economic outcomes. Our method, which requires only publicly available data, could transform efforts to track and target poverty in developing countries. It also demonstrates how powerful machine learning techniques can be applied in a setting with limited training data, suggesting broad potential application across many scientific domains. Data imagery of the report is available on the project website.
 

How satellites and social media help us anticipate the needs of conflict-affected countries

The World Bank Group plays a major role in recovery and reconstruction efforts in conflict-affected countries. Therefore, it is important for us, in collaboration with international partners, to engage in assessing the needs and planning for recovery and reconstruction as much ahead of time as possible. In recent times, we have been conducting broad-brush damage assessments in active conflict situations using innovative remote-based techniques like satellite imagery or social media analytics to provide not only damage numbers and trends but also qualitative information on the status of various services. These new approaches have helped us maintain situational awareness of and be ready for recovery when the situation allows.

During the initial stages of recovery efforts, supporting local-level recovery initiatives can serve as a springboard for large-scale reconstruction programs, which remains our biggest comparative advantage. Therefore, there is a need to expand these assessments to include other elements of recovery, which would inform preparation of multi-sectoral local level recovery interventions in the short-term, and major reconstruction programs in the medium- to long-term.

Digital technology means development is now happening outside the system
The Guardian
I recently spent an evening at the University of Sussex talking to students interested in a career in the international development and non-profit sectors. That might not sound particularly interesting at first, except that I've never had a job in either. There's a general assumption – and not an unreasonable one – that if you want a career helping solve some of the bigger challenges facing people and the planet that you reach out and volunteer, intern and work at some of the largest institutions taking on those problems. But there is another way. A few decades ago, if you wanted a career in development you'd have to be a teacher, doctor or build dams. The spread of the internet and the march of the mobile phone have changed all that. Now, anyone with a computer and internet connection can build an app in their bedroom that helps to improve the lives of millions of people around the world, or develop an idea which goes viral. And I speak from experience, developing text messaging platform FrontlineSMS a few years ago with little funding or resources, which now is driving thousands of social change projects in more than 170 countries.

Studies Show: People Want Democracy to Deliver the Goods
Foreign Policy
Does the average person consider governance when they think about the things that affect their everyday lives? In a new Overseas Development Institute (ODI) paper that assesses views on governance based on survey data from around the world, we find that they do. But governance has many aspects, and there are some that are more important to people than others. In general, people seem to be concerned first and foremost about state performance and the ability of governments to deliver on key needs and expectations in areas including economic management, growth stimulation, job creation, health, education, or a more equitable distribution of goods and services. Corruption is a central part of this story, since it has such a big impact on people's satisfaction with their governments and their perceptions of its performance overall.

Tracking light from space: Innovative ways to measure economic development

One of the most common challenges in economic development is collecting comparable data. The information age is changing that as the diffusion of information technology meets changes in institutional attitudes toward data sharing. New capabilities are meeting old capabilities on our desktop computers and it is leading to some bright ideas in how to measure and evaluate economic development.

The first that comes to mind is nighttime lights imagery – colloquially referred to as nightlight data. Nightlight refers to light resulting from human activity visible from outer space at night.  Astronomers call it light pollution. This is pretty accurate since nightlight is the waste by-product when humans use of energy that is emitted or reflected straight up into the sky – these could be city lights, car headlights, fires, etc.
