The latest transformations in technology and digitization have led to a more connected world by facilitating communications, even more so due to the dramatic increase in access to digital technology in all aspects of life—from smartphones to new ways of connecting via social networks and other online platforms.In emergency situations, new technology now allows for real time interactions between all actors involved. Relationships with beneficiaries of humanitarian relief are evolving, as more and more of the exchanges are made via digital tools such as messaging apps and digital cash payments. Meanwhile, technology can be used to allow for an easier and more direct access to humanitarian aid, for example through self-registration.As the use of new technology spreads, digitized information is generated, shared and made available. This new information environment presents both challenges and opportunities for humanitarian organisations interested in using this information for the benefit of those they serve, while questions of privacy and data protection regularly arise. As it is often the case, ethical and legal considerations are being addressed in parallel with the evolution of technology.There are also important risks that must be considered in terms of cyber security and data privacy. Another aspect of the virtual space is so-called cyberwarfare, as subject that was at the forefront in 2017 with the launch of the updated Tallinn Manual on law applicable to cyber warfare in March 2017 and calls by some for a "digital Geneva Convention".This edition of the Review will cover these topics and more. Contributors may choose to write on such topics as digital communication and humanitarian work, the information environment, cyberwarfare and IHL or the impact of new technology on the humanitarian field.Authors are invited to send submissions to the Review's editorial team, preferably in the form of a Word document, at review@icrc.org. The deadline for submissions is 31 January 2018. Additional guidelines for authors available here.
