The project’s main objective is to identify and analyse fluxes and patterns of internal and transborder human migration induced by climate change. The observational study will take place in the Ganges-Brahmaputra-Meghna (GBM) Delta in India and Bangladesh and the Mekong Delta in Viet Nam and Cambodia. The studies’ outputs will allow us to provide to governments and public actors involved accurate measures in a decision making process. These outputs will be based on the development of innovative analytical methodologies in order to support human migration and displacement and design adaptation solutions for local population. The cross-border aspect of these deltas and the issues they face by the diversity of their political links will allow the project to produce methodological tools and recommendations on migration management useful for the European Agenda on Migration. The project’s outputs will also respond to the objectives of the Paris Agreement in terms of local sustainable development. These two deltas (GBM and Mekong) are highly populated (respectively 1000 and 500 inhabitants/km2) and heavily exposed to monsoon, rainwater floods, flash floods, and cyclones floods as well as to the induced effects of climate change. Human Migration linked to climate change should lead by 2030 to a demographic spatial restructure of areas and territories already highly under pressure in most coastal and metropolitan cities. Access to services and housings for the new-comers are considered challenging for the hosting local authorities, notably in terms of forecasting urban planification and investment, in a precarious context of social and property policies. The project aims at an early stage, to produce tools to evaluate the vulnerability of human population migrating and local population in order to submit recommendations on land use planning on ‘under pressure urban and rural territories. Migration drivers are physical, social, and economic and differ according to the impacted communities. Risk perception is different for these communities, and their mitigation measures are usually traditional in terms of housing construction and adapted solutions. The project MOVINDELTA will include the integration of empirical analysis and computer-based social simulation modelling linking documentary evidence and socio-economic and -political data with model design, including a cognitive architecture, model source code and the outputs from simulation models. For the project considered as a whole, the specificity - and strength - of our consortium is to gather experts from very different fields, ranging from social and human sciences to fundamental environmental sciences. Our consortium has established a long-lasting collaborative framework with local institutes in Third as well as European countries working together on climate change, risks and vulnerability of population. Several projects in the GBM and Mekong deltas have been concluded successfully from this collaboration, leading to a strong network in the field of science, social sciences and sustainable development. Finally, the aim of the project is to broaden the partnership to researchers, lecturers, professors, the civil society (NGO) but also the private sector at an European (Germany, Netherlands and UK) and international level to extend the disciplinarity potential of the project within the call.
