Food security is one of the main global challenges for the coming decades. Climate change and commercial exploitation of seed technology are its biggest threats. We are all interconnected and depending on a global food system. This system relies on our planets’ biodiversity. More than ever, our food system requires not only a wide range of plant varieties resistant to pests and diseases, but also varieties that are capable of adapting to shifting conditions of increased salinity, drought and flooding. The Sowing Diversity=Harvesting Security program aims to improve this diversity and to change the current unsustainable and unequal food production systems.
