I am doing a literature review on cocoa demand and supply. The norm is cocoa demand is going up slightly. However, I was reading an article stating:
Demand for cocoa is predicted to rise by 30% by 2020 but without empowering and investing in small-scale farmers, the industry will struggle to provide sufficient supply.
Is it appropriate to say
The demand for cocoa was predicted to increase by 30% by 2020 as claimed by .... (2020).
I have used 'according to' several times now and thought to change it.
