Cocoa Crisis: Study Warns of 50% Land Loss in West, Central Africa by 2050

A new study has revealed that ongoing climate change is likely to significantly impact cocoa production in West and Central Africa, which accounts for over 70% of the world’s cocoa supply. Conducted in Ivory Coast, Ghana, Nigeria, and Cameroon, the research predicts that by 2050, nearly 50% of currently suitable cocoa-growing areas may no longer support cultivation due to rising temperatures and shifting rainfall patterns. The findings highlight the urgent need for adaptive strategies to sustain cocoa production while preventing deforestation.

Key Findings

Study Coverage

• Conducted in four major cocoa-producing nations—Ivory Coast, Ghana, Nigeria, and Cameroon.

Cocoa Dependence

• Ivory Coast and Ghana currently produce over 60% of the world’s cocoa.

Methodology

• Used the CASEJ mechanistic cocoa crop model to simulate climate change effects on yield.

Climate Change Impact

• Temperature and rainfall variations are reducing suitable cocoa-growing regions.
• Northern Ivory Coast and Ghana expected to experience a 12% decline in yield.
• Nigeria and Cameroon likely to see declines of 10% and 2%, respectively.

Shift in Cocoa Production

• Suitable cocoa regions may move from Ghana and Ivory Coast to Nigeria and Cameroon.
• Cameroon’s forests could face deforestation due to cocoa expansion.

Challenges and Uncertainties

• Effect of increased CO2 on cocoa yield remains uncertain.
• Climate change could influence flowering, fruiting, and pest outbreaks.
• Further research is needed to mitigate adverse effects on cocoa and other crops.

About Cocoa

• Cocoa is an important plantation crop grown for chocolate production worldwide.
• It is a crop of humid tropics, native to the Amazon Basin of South America.
• Grows mainly between 20° latitude north and south of the equator.

Required Climatic Conditions

• Can be grown up to 300m above mean sea level.
• Rainfall: Requires an annual rainfall of 1500-2000 mm.
• Temperature: Thrives in 15°-39°C, with an optimum of 25°C.
• Soil: Prefers deep, well-drained soils, particularly clay loam and sandy loam, with a pH of 6.5-7.0.
• Shade Requirement: As an understorey crop, cocoa requires 50% filtered light.

Major Producing Regions

• Global: About 70% of the world’s cocoa beans come from four West African countries: Ivory Coast, Ghana, Nigeria, and Cameroon.
• India: Mainly cultivated in Karnataka, Kerala, and Tamil Nadu as an intercrop with Arecanut and Coconut.
