Vital crop growth through usage of microalgaebased biostimulants (VIGOROUS).

The ongoing population and consumption growth is rapidly increasing the demand for agricultural food production. At the same time, increasing environmental awareness raises concerns about the choice of agricultural practices in terms of their impact on ecosystem functioning and biodiversity. As the need to satisfy these demands is further exacerbated by the interrelated impact of climate change, the agriculture sector is left with the challenge to meet the growing demand for food through climate-adapted methods that alleviate the environmental impact of agriculture and increase the resilience to climate change. Dealing with this challenge requires a multifaceted global approach, including an optimized use of nutrient input and an increased crop tolerance to environmental stress. To this end, innovative technologies based on bioresources include the use of microalgal biostimulants to improve crop yield while lowering the environmental footprint of agriculture. However, the limited amount of scientific evidence that 1) microalgal biostimulants effectively improve agronomic efficiency, including a lack of understanding on the underlying mode of action, and that 2) microalgal biostimulants do not present a risk to the natural environment hampers the further development and establishment of this technology. Moreover, market success of microalgal biostimulants hinges on an optimized cultivation process to ensure a high yield and a standardized content of microalgal products. The VIGOROUS research consortium will address these knowledge gaps to facilitate evidence-based application of microalgal biostimulants and to support a science-based biostimulants industry to sustainably intensify agricultural production with an enhanced resilience to climate change.
