The different research teams supported by the “Adaptation to Climate Change in Agriculture and Forestry” (ACCAF) metaprogramme during its last call for projects (AMI2017) have presented their progress and deliverables.

The LACCAVE 2.21 project has developed a scientific network and interdisciplinary research on climate change adaptation strategies in the French vine and wine sector. Systemic and participatory approaches are favoured. Ten seminars and numerous scientific and technical publications cover different areas and scales of adaptation. Two operations are highlighted: a thesis proposing an approach to the design/evaluation of options at the local level and the construction of a national strategy based on foresight.

The VACCARM project, which brings together a variety of stakeholders and complementary methodologies, has made it possible to co-design a range of maize cropping systems incorporating agroecological practices and to highlight their promising performance. The evaluation tool integrating the concept of vulnerability is still being developed. It will allow the material and structural, as well as cognitive, resources of maize farmers to be taken into account.

The search for food security in India is based on irrigated crops. Over the past 30 years, the increase in irrigated areas has been based mainly on the development of the pumping of groundwater. But this resource is under threat since water taken for irrigation is not replaced. What will happen in an even warmer climate? The AICHA project has modelled the hydrological, economic and agronomic functioning of a watershed in order to identify the most sustainable production systems, as well as possible regulatory measures.

Extreme climatic events pose a challenge to the agriculture of tomorrow. However, their repetition can generate a beneficial memory effect allowing plants and their offspring to acclimatise.

With climate change, there will be significant changes to the forage production used to provide daily feed for cattle and sheep. What changes will farmers have to make on their farms to maintain an economically, environmentally and socially consistent and efficient system? The FARMATCH project has focused on preparing farmers by confronting them with virtual scenarios using computer simulations.

The PopMicroClim project, funded by INRAE, aims to explore whether the tree root microbiome can be used to improve tree resistance to climate change and to identify the microorganisms involved in improving this trait. If so, the results could be used to try to design microbial inocula that could improve the resistance of seedlings and trees to climate change

Ixodes ricinus, the vector of Lyme disease, and Hyalomma marginatum, the vector of Crimean-Congo haemorrhagic fever virus, represent a threat to human health. Living mainly outdoors, they are subject to weather conditions. Through an approach combining observations, experiments, modelling and social sciences, the CLIMATICK project studied the distribution and dynamics of these ticks, under current and future climates, and provided initial tools for the co-construction of prevention and/or adaptation strategies.

The project specifically concerns wheat, a major world food crop. The main objective of Educ.net is to develop a community of scientists to address climate-related emerging plant diseases, using data and models as communication tools.

Drought&Fire aims to gain a better understanding of the determinants and physiological processes of foliage water content dynamics in vegetation under drought conditions, to build a model of these processes and to assess the effects of water content on fire risk. In particular, the project developed the SUREAU-ECOS plant hydraulics model, which predicts desiccation and mortality of tree and shrub foliage under drought conditions. Fire activity in south-eastern France is well correlated with the water content of the foliage, whose summer variations considerably affect fire propagation
