Innovations play a significant role in the primary sector (i.e., agriculture, fisheries and forestry), ensuring a greater performance towards bioeconomy and sustainability. Innovation is being progressively applied to examining the organization of joint technological, social, and institutional modernizations in the primary sector. Exploring the governance of actor relations, potential policies, and support structures is crucial in the phase of innovation, e.g., during research activities, often applied at the national or sectorial scale. However, when opposing normative guidelines for alternative systems of agriculture arise (e.g., the industrial agriculture paradigm), modernizations in agricultural and forestry may contribute to outlining more sustainable systems. To date, innovations in the primary sector do not seem as advanced as in other sectors, apart from industrial agriculture, which sometimes appears to be the most encouraged. The present review aims to shed light on innovations that have been identified and promoted in recent years in the primary sector, including agriculture and forestry. The need to pursue sustainable development in this sector requires the inclusion of a fourth dimension, namely energy. In fact, energy sustainability is an issue that has been much discussed in recent years. However, the need for progressive technological progress is indispensable to ensure long-lasting energy efficiency. The aim is to understand what innovations have been implemented recently, highlighting opportunities and limitations for the primary sector.
