The current mainstream of cultivation methods, food systems and related industries are in urgent need of innovation and large-scale transformation.
Their expensive chemical inputs depend on petroleum products, their fluctuating prices and unpredictable availability. They are responsible for 85% of biodiversity loss, use 70% of the world’s freshwater and emit 35% of global GHG, while challenging the health of billions of consumers, farmers and foresters. Chemical farming has not solved hunger and malnutrition. 800 million people remain food insecure, even as conventional agriculture occupies 50% of habitable land, causing massive deforestation and gradually degenerating farmland. In Brazil alone, experts estimate that around 100 million hectares of farmland, much of it former forests, have become unusable – more than the combined size of Kenya and Germany.
Even after centuries of trial and error, conventional agriculture has also not yet resolved the economic challenges of most of the 550 million family farmers that produce 80% of global food supply. Yet, according to the World Bank, the vast majority live in financially precarious situations, earning less than US$2 a day. Especially in the Southern Hemisphere, countless farmers are financially trapped by ever more expensive chemical inputs and copyright protected seeds, combined with high interest rates and rising debt that has led to many suicides. Therefore, unsurprisingly, the average age of farmers has grown to around 55 years because youth leave the land due to limited economic opportunities. For these and other reasons the current mainstream of agriculture is a system in urgent need of innovation and large-scale transformation.
Chemical agriculture will be a key aspect of food systems for many more years and will benefit from its own innovations. But like the combustion engine and carbon-based energy sources, carbon-based chemical agriculture is fundamentally a technology of the past with too many negative side effects. In fact, the United Nations and research institutions using ‘true cost accounting’ estimate that the combined direct and indirect financial cost of the current food system already exceeds the total market value of global agricultural production.
