[en] Regional plans of air quality monitoring are planning tools for the implementation of air quality improvement actions at the regional scale. A first document presents the methodology used to prepare an inventory of all atmospheric pollutants in Provence Alpes Cote d'Azur region (Southern France). A comprehensive identification of all energy consumption sources is made and then applied to each sector of activity (energy, industry, residential, agriculture, transport..) to calculate the amounts of atmospheric emissions. The second document presents the 2017-2021 air quality monitoring plan for Provence Alpes Cote d'Azur region: the air quality challenge, the new working model and the exchange with actors, the challenge guidance (environmental exposure to air pollution, air/energy/climate/health relation, environmental communication, new technologies for expertise improvement), preparing to tomorrow's monitoring activities, changes in the economic model

[en] A first report proposes an overview of the situation and perspectives related to climate change in the Provence-Alpes-Cote-d'Azur region. Based on various publications, it comments climate predictions for this region, proposes an overview of the situation of the water resource and of its necessary protection, describes various disturbances of the environments, effects of climate change on economic sectors and productive areas, and more particularly on town planning and building, discusses the objectives of an energy transition, and also health risks related to climate change. The second report presents some characteristics of the Mediterranean climate and stakes related to climate change (notion of climate-related risks). It proposes an overview of the past and present regional climate (main evolutions of the past climate, refined knowledge of the present climate with instruments and techniques of data spatialization), and proposes prospective elements (understanding of emission scenarios, climate trends for the region, first indicators for four towns of the region, examples of recent thematic studies). The third report proposes a focus on the situation of the regional agriculture in front of climate change (phenology of sustainable plants, risks and opportunities for agriculture, wheat cultivation, innovative practices to improve the sustainability of agricultural systems, scenarios to anticipate the adaptation of Camargue rice production systems, a multidisciplinary initiative for a better assessment of stakes of climate change in mountain pastures), and a discussion of the new constraint on the Mediterranean forest due to climate change (operation of Mediterranean forest systems, adaptive forestry, impact of climate change on forest health and fire risk, the difficult interpretation of signs of climate change in coastal forests, the future of mountain forests, and the impact of ozone on the Mediterranean forest).
