It is vital that Africa has a clear and cohesive vision in place for how it plans to use its gas reserves, says New Partnership for Africa’s Development Business Foundation senior project manager John Rocha. Speaking at the Africa Gas Forum, on Monday, he pointed out that African countries have proven natural gas reserves of around 503-trillion cubic feet, while African gas consumption is set to rise by 3.1% a year, or a combined 150-billion cubic metres, up to 2022.
