Descripción: The Montpellier global science conference on CSA: Will address key research issues, gather CSA facts and figures from developing and developed countries and support a collaborative effort with broad social participation. Special attention will be given to vulnerable countries and populations. It will therefore contribute to the strengthening of a CSA scientific community and will provide a further opportunity for developing a global research agenda. Will aim to reduce the science-policy gap. The conference takes place a few months before the 21st Conference of the Parties (COP21) of the United Nations Framework Convention on Climate Change (UNFCCC, Paris, France, December 2015). The COP21 will be a milestone in the international climate negotiations, with the goal that all countries are committed by a universal binding climate agreement. It is hoped that the COP21 will witness a “paradigm shift” where the climate challenge is not any more a necessary "burden sharing" of emissions, but also an opportunity for job creation and wealth, inventing new patterns of production and consumption. Therefore the Montpellier CSA conference will be a unique opportunity for the research community to update knowledge on CSA and to provide recommendations for policymakers. Will pave the road for future cooperation initiatives to be taken in terms of joint and collaborative scientific efforts.
