Presenting the CARPA project

The ICT4D project CARPA, funded by NWO-WOTRO had its first stakeholder workshop today at the Amsterdam Business School of UvA. From our project proposal: The context for CARPA (Crowdsourcing App for Responsible Production in Africa) lies in sustainable and responsible business. Firms are under increasing pressure to ensure sustainable, responsible production in their supply chains.. Lack of transparency about labour abuses and environmental damages has led some firms to cease purchases from the region

.With an interdisciplinary partnership of local NGOs and universities in DRC, Mali, and South Africa, this project aims to generate new evidence-based knowledge to improve transparency about business impacts on responsible production.

Co-creating a smartphone application, we will use crowdsourcing methods to obtain reports of negative social and environmental business impacts in these regions, and follow them over time to understand access to justice and whether and how remediation of such impacts occurs. Data integration and visualization methods will identify patterns in order to provide context and clarity about business impacts on sustainability over time. A website will be developed to provide ongoing public access to this data, including a mapping function pinpointing impact locations.

The project will be led by Michelle Westermann-Behaylo from UvA, with the research work on the ground being executed by UvA’s Francois Lenfant and Andre Baart. Marcel Worring and myself are involved in supervisory roles.

A Voice Service Development Kit for the Kasadaka platform

[This post is written by André Baart and describes his MSc thesis]

While the internet usage in the developing world is still low, the adoption of simple mobile phones is widespread. A way to offer the advantages of the internet to these populations is voice-based information systems. The KasaDaka voice-services platform is aimed at providing voice-services in the context of ICT for Development (ICT4D). The platform is based on a Raspberry Pi and a GSM modem, which enables affordable voice-service hosting, using the locally available GSM network. The platform takes into account the special requirements of the ICT4D context, such as limited internet connectivity and low literacy rates.

This research focuses on lowering the barrier to entry of voice-service development, by reducing the skill set needed to do so. A Voice Service Development Kit (VSDK) is developed that allows the development of voice-services by deploying and customizing provided building-blocks. These building blocks each represent a type of interaction that is often found in voice-services. (for example a menu, user voice input or the playback of a message) The researcher argues that the simplification of voice-service development is an essential step towards sustainable voice-services in the ICT4D context; As this increases the potential number of local voice-service developers, hremoving the dependency on foreign (and thus expensive) developers and engineers. This simplification should ideally be achieved by providing a graphical interface to voice-service development.

The VSDK was evaluated during the ICT4D course at the Vrije Universiteit Amsterdam, where students built applications for various ICT4D use-cases using the VSDK. Afterwards a survey was conducted, which provided insight on the students’ experiences with voice-service development and the VSDK. From the results of the evaluation is concluded that the building-block approach to voice-service development used in the VSDK, is successful for the development of simple voice-services. It allows newcomers to (voice-service) development, to quickly develop (simple) voice-services from a graphical interface, without requiring programming experience.

The VSDK combined with the existing KasaDaka platform provides a good solution to the hosting and development of voice-services in the ICT4D context.
