Future food security is one of the key global challenges facing society. Climate change presents significant threats to our ability to produce staple food crops – particularly in regions already vulnerable to droughts. Dr Kahiu Ngugi and his research team from the University of Nairobi and other institutions in Kenya investigated numerous varieties of sorghum – one of the world’s most important cereal crops. Their aim was to find new genes that would allow the crop to withstand both drought and a common parasitic weed.

Methane is one of the most potent greenhouse gases that contributes to the global climate crisis. As this gas is produced in the digestive systems of cattle, methane represents one of the greatest problems faced by the farming industry. Dr Robert Bryant, Dr Langdon Martin and their team at Warren Wilson College, North Carolina, propose an innovative feed supplement for cattle that helps to significantly reduce methane emissions: waste yeast from craft breweries. If used on a large scale, this new supplement could significantly decrease emissions associated with cattle farming, while also creating a new use for a waste product of the craft beer industry.
