A Comprehensive Economic Examination and Prospects on Innovation in New Grapevine Varieties Dealing with Global Warming and Fungal Diseases

Abstract

The present study focuses on the assessment of the development perspectives of the new grape varieties that are resistant to fungal diseases and thus promote the reduction or the suppression of phytosanitary treatments. The study also discusses new grape varieties dealing with global warming. Our methods rely on direct surveys with researchers and stakeholders completed with a synthesis of the scientific literature and edited research programs. This approach proposes an explanatory and a comprehensive investigation. It includes an overview of the current state of the art of the supply of technology, the presentation of the strategies of the main actors and stakeholders involved in the innovation chain, a synthesis of the current scientific and technical controversies, and an analysis of the influence of the institutions and legislation. Furthermore, we provide an evaluation of the previous research program on new grape varieties of the French National Institute for Research in Agronomy (INRA) and of the outcome of the diffusion of new grape varieties implemented in the south of France. This analysis will allow us to discuss the conditions for the success of this innovation as a competitiveness factor.
