African countries will suffer significant economic loss after 2050 if global warming is not limited to below 2°C, a new study by the Center for Global Development has found.

Environment and energy economist Philip Kofi Adom is the author of the report. He synchronised many years of research by climate change scientists and researchers and found that west and east Africa will fare worst. We asked him about his findings.

You found climate change will reduce Africa’s crop earnings by 30%. How will this affect people?

If climate change continues on its current trend, crop production in Africa will decline by 2.9% in 2030 and by 18% by 2050. About 200 million people risk suffering from extreme hunger by 2050. The crop revenue loss of approximately 30% will cause a rise in poverty of between 20% and 30% compared to a no-climate-change scenario.

How this will happen is that climate change will drive agricultural production down, so crop sales will suffer although scarcity will raise prices.

In Africa, 42.5% of the working class is employed in the agricultural sector. The incomes of those, mostly rural, workers will decline. Already, a higher share of people living in rural areas are poor and most impoverished people in Africa are concentrated in the rural areas. The decline of the agricultural sector is likely to push more people into severe poverty.

We will also face food security issues and those who work in the agricultural sector will face the risk of losing jobs. Rural farmers who rely only on rain and have no irrigation systems to grow their crops will suffer the most.
