Climate change is one of the greatest threats to food security, poverty reduction and sustainable development across the world. To cope with the consequences of climate change, innovative solutions are needed. Blockchain technology is one of them – but what is it and how can it be used?. The United Nations recognizes innovation as a driving force in helping the world to achieve food security and the Sustainable Development Goals (SDGs). While innovation is not only about technology, digital solutions are becoming increasingly important. According to a new report on Applying blockchain for climate action in agriculture: state of play and outlook from the Food and Agriculture Organization of the UN (FAO) and Wageningen University & Research (WUR), blockchain technology has a lot of potential to support effective climate policy in the agriculture sectors and to measure the effectiveness of climate action. The report outlines the limitations and potential applications of blockchains in agriculture and how it may be used in the context of climate change.
