One of the great challenges of agriculture in SUDOE is to deal with the consequences of climate change, in particular the increasingly early droughts. Freshwater availability will continue to decline, making the agricultural sector, highly dependent on water resources, particularly vulnerable. Therefore, conditions must be created to promote the resilience of agriculture by improving the use of an increasingly scarce resource. To meet this challenge, the digital transformation of agriculture is essential. In support of this transition, SMART GREEN WATER project partners will promote the implementation of smart specialisation strategies (S3) for a more sustainable agricultural sector based on increasing the sectors digital capacities, thus strengthening the socio-economic fabric of rural areas. Thanks to transnational cooperation, the project partners will take advantage of the wealth of diverse contexts: regions of Spain and Portugal where historical water shortages have favored their collective management, while, in southwestern France, irrigation is more recent and individual. The proposed solutions, tested through pilot and transferable actions, to the different contexts, will allow to identify the best tools to meet the needs of farmers. Innovative irrigation optimisation technologies will be consolidated and disseminated through experimentation in partner regions. In short, digital tools will be made more accessible through a transnational training programme and the link between innovative companies and the agricultural sector. The transnational strategy developed and validated thanks to proven solutions will connect innovation ecosystems and public administrations with the agricultural sector as an end user. Support for digitalisation will ensure a more water-efficient agricultural sector and rural territories that are more resilient to the effects of climate change.
