Coffee is one of the most widely-consumed beverages in the world. But with climate change threatening the world's two main coffee species, will that change? Coffee scientist and researcher Dr. Aaron Davis says even with rising temperatures, and more drought -- that doesn't have to be the case. This week on What About Water? we hear why reintroducing forgotten wild coffee species will be the key to growing enough coffee in the future. In this episode, Jay learns about the professional coffee-tasting process and just how much flavor factors into the equation for coffee farmers' bottom lines.On the Last Word we meet Daniel Sarmu, a coffee development specialist in Sierra Leone who is helping small farmers grow heat-tolerant Stenophylla coffee. He is also searching for more Stenophylla coffee trees in the wild. Aaron Davis Dr. Aaron Davis is the Senior Research Leader of Plant Resources at the Royal Botanic Gardens, Kew (UK). Davis is the leading authority on coffee species and has traveled widely to countries in Africa to study coffee in the wild. His team at Kew is dedicated to the identification and understanding of the beneficial traits of crops and associated organisms, particularly within the context of environmental stress resilience and climate change.Davis' work on coffee spans over 30 years, and includes the naming and classification of coffee species, molecular (DNA) studies, conservation, climate change and resilience, and sustainable development. More recently he has published research on the value of wild coffee species (and diversity) for the sustainability of the global coffee sector. Ongoing and new work includes the development of climate resilience methods and the use of wild coffee species for the development of next-generation coffee crops. Daniel Sarmu Daniel Sarmu is a Coffee Development Specialist from Kenema, Sierra Leone. He has worked in the development world for over 20 years, primarily in agriculture, helping small farmers maximize their profits in the coffee industry. In 2018, Daniel re-discovered the long-forgotten Stenophylla coffee plant in the hills of Sierra Leone alongside Dr. Jeremy Hagar and Aaron Davis. In recent years, Daniel has also written Sierra Leone's coffee policy and is putting finishing touches on it so that small farmers across the country can use it.
