How agriculture benefits from research through extension and engagement Different sectors benefit from science in different ways. In the case of agriculture, innovations based on science often originate from providers of farmers, for example in the form of seeds or machinery. However, the diffusion or uptake of innovations is difficult, in particular for small farmers.

European and global science policy have been restructured around ‘global challenges’ and ‘research excellence’ to commit to societal impact. Our current global challenges, including climate change, destruction of nature, and increasing global inequality, require critical interrogation of the contributions and consequences of science.

Universities in the Leiden Ranking 2023 As Figure 1 shows, the number of universities in the Leiden Ranking keeps increasing. Like in the last three editions of the ranking, a university needs to have at least 800 fractionally counted publications in the most recent four-year time window to be included in the ranking. This year 1411 universities meet this criterion, 93 more than last year and 235 more than in 2020.

Imagine academic publishing that is fast, transparent, and free. Is that a pipe dream or something within reach? We already have preprint publishing (fast), open peer review (transparent), and diamond/overlay journals (free). If we could connect these disparate initiatives, would that make our dream come true? And how could this best be done? These are questions that are currently being discussed by us and others at Leiden University.

Academic research has become increasingly complex, multidisciplinary, collaborative, and transnational. The institutions that underpin research - including communication and evaluation systems - are trying to keep up, with varying levels of success. At the same time, our society is facing major challenges, including existential global health, welfare, and sustainability issues.

The scientific community is moving towards a more transparent way of conducting and reporting research. Scientific publications are becoming more and more openly accessible but openness should also extend to peer review, preprinting, preregistration, data sharing, metadata availability, and related issues.Research funders and other stakeholders are putting a significant effort into promoting open science practices in scholarly communication.
