By 2050 it is estimated that the global population will surpass nine billion. Food production must be sufficient to equitably feed such a growing population. With productive arable land and freshwater resources severely constrained in many parts of world and unsustainable agricultural practices and climate change, it is imperative that we transform our agrifood systems to make them more sustainable. Here are 4 ways science, technology and innovation can help transform agrifood systems 1. Enhancing access to services through the internet and digital applications Thanks to the narrowing of the ‘digital divide’ and the spread of digital technologies, farmers can use mobile devices to access market information, weather data or connect with buyers. 2. Upgrading value chains FAO’s Sustainable Food Value Chains Knowledge Platform looks at value chains holistically and connects producers to consumers. This tool also helps key players in value chains identify areas of underperformance and intervene accordingly. 3. Using innovation to reclaim underutilized spaces for urban agriculture Through its Green Cities Initiative, FAO supports decision-makers in advancing urban agriculture and ensuring that appropriate technologies are available to all. 4. Developing irradiated vaccines for animals Irradiation technology allows development of safe vaccines for animals, which in turn helps to bolster the livestock industry in countries where disease represents a barrier to sustainable production. By harnessing science, technology and innovation, we can transform our agrifood systems and build a sustainable future of food for all.
