Food security is highlighted as an immediate concern for humanity, with further threats being added with climate change that has the potential to severely disrupt the existing food system. The digitalisation of agriculture is described as a way out of this impasse. The paper argues that small and marginal farmers face a challenge because they are mostly engaged in production with no linkage with the other components of the agricultural value chain, like processing, marketing or even input procurement. They also remain on the wrong side of the digital divide. It is necessary that they are provided with the digitalisation benefits as a public good through effectively chosen public investments. Moreover, it is imperative to provide them with the required capacity building initiatives so that they can use the benefits of the technology in an efficient manner. The G20 is the right forum to bring these issues forward from a global perspective.
