The Intergovernmental Panel on Climate Change stresses the urgency of adapting to Climate Change, relayed by the ‘Take urgent action’ injunction of the 13th goal of United Nations. States efforts consist mainly in climate plans. But climate risk is amplified by a governance risk. The more the implementation of climate plans and policies and their change capacity are incremental, the more their failures and ‘myopia’ are proven, and the more the ‘climate super wicked problem’ becomes a ‘tragedy’, because time is dramatically running out. Climate governance is confronted to two major challenges that deals with political and policy temporalities : how to integrate long term climate impact into today’s policy ? How to accelerate the implementation of climate plans? Literature identify two pathways to end this 'tragedy': institutional innovation and reinforcement of authority, even noting that authoritarian environmentalism is more efficient than democracy. From the case of adaptation of agriculture, the main assumption of the project is that institutional innovation in the procedural instruments for climate governance is one of the main ways to end the ‘tragedy’. However, there is a scientific weakness that prevents answering the APIICC project issues : i) the literature on institutional innovation in climate governance is scarce ii) or it states broad principles with little empirical knowledge ... iii) ... especially on procedural instruments (rarely observed, monographs) iv) or the themes on institutional innovation, procedural instruments, and political and policy temporalities are disconnected. The project has three objectives: i) To ameliorate this weakness by producing first-hand empirical knowledge on innovative procedural instruments, by focusing in particular on their links with political and policy temporalities (capacity of accelerating implemention and integrating long term) and with authority, and by studying them on a large comparative scale (11 countries, 11 national and 11 local plans) ii) To produce a model for assessing institutional innovation iii) to develop sets of recommendations for innovative governance for agricultural transformational adaptation, collaboratively with stakeholders (approach of social responsibility of science). The project has three original features: i) unlocking knowledge on climate governance ii) comparing large-scale data in the North and South and iii) producing solutions for climate action with stakeholders themselves. To achieve this goals, the variables mobilized are: i) objectives of innovation (horizontal policy integration, quality of governance, adaptive governance, that allow acceleration of implementation and integration of long term objectives) ii) types and structure of the procedural instruments iii) their positioning on the authority/innovation cursor iv) origin of the instruments (politics, administration, international…) v) origin of the innovators (expertise, production chain, administration…) vi) their innovation capacity (analytic, navigating complexity, learning collaboratively…) vii) political regimes, policy styles. A first work package (WP1) will refine these variables. WP2 deals with variables i) to iii) (‘Product innovations’, types and structures of innovative procedural instruments). WP3 deals with variables iv) to vii) (‘process innovations’, institutional innovation policy process and innovation capacity). WP4 will elaborate recommendations and guidelines for institutional innovation for transitional governance for adaptation. The WP0 will : i) manage the progress of the project tasks ii) harmonize the implementation of the research protocol and the challenge of data collection and treatment for 11 countries. An international and interdisciplinary team (political scientists, sociologists, economists, agronomists and ecologist) of 17 researchers, specialized in climate issues, will develop the project and supervise 24 young researchers (master, PhD, post-do
