Full-sun cocoa farming is currently the most widespread cocoa cultivation system in humid and sub-humid Côte d’Ivoire. Higher short-term yields from increasing surfaces under cultivation in this farming system have contributed to the country being ranked as top cocoa producer in the world.

Climate and weather conditions, such as the North Atlantic Oscillation, precipitation and temperature influence the birth sex ratio (BSR) of various higher latitude species, including deer, elephant seals or northern human populations. Although, tropical regions show only little variation in temperature, climate and weather conditions can fluctuate with consequences for phenology and food resource availability. Here, we evaluate, whether the BSR of chimpanzees, inhabiting African tropical forests, is affected by climate fluctuations as well.

Cocoa production will become increasingly difficult in the key growing regions of West Africa by 2030 because of climate change, according to a new study.

In 2002 CREPA initiated a regional research and demonstration programme on ecological sanitation in seven West African countries. ECOSAN is focused on simultaneously improving sanitation and food production. This is done by making urine and faeces more hygienic and then using them as safe fertilisers.
