The objective of this thematic paper is to provide the readers with a better understanding of how DTM can contribute to data gathering and analysis on human mobility in the context of environmental degradation, climate change and disasters. The paper formulates recommendations for DTM practitioners to improve tools and explore new analytical approaches to allow IOM to be at the forefront in this growing field.

Through a critical analysis of current DTM practices, the paper proceeds to assess DTM current contributions, strengths and weaknesses in understanding human mobility in the context of environmental degradation, climate change and disasters and draws lessons from previously undertaken surveys and assessments. This introspective process serves to highlight opportunities to improve current tools and practices, as outlined in a set of targeted recommendations. Finally, this paper paves the way for more advanced analyses that could be carried out by taking into consideration external sources of data, such as publicly available meteorological databases, alongside information collected by DTM. The thematic paper thus seeks to assist practitioners in considering more consistently the possible impact and explanatory power of environmental factors in the context of population movements, and to apply an analytical lens focused on this intersection when interpreting data.
