With related literature discuss background of coffee growing in Uganda with the latest references in one detailed paragraph

Coffee growing in Uganda has a rich history that dates back to the 19th century. According to the Uganda Coffee Development Authority (UCDA, 2020), coffee was introduced to Uganda from Ethiopia around 1860 by Arab traders. The British colonial government later promoted coffee cultivation in the early 20th century, and by the 1950s, coffee had become a major export crop. The UCDA (2020) also notes that the government of Uganda has since implemented various policies to support the coffee sector, including the liberalization of the coffee industry in the 1990s. Today, Uganda is one of the top coffee-producing countries in the world, with the majority of its coffee grown by smallholder farmers. The country's coffee sector has also been influenced by factors such as climate change and market dynamics (Bunn et al., 2019). Despite these challenges, coffee continues to play a significant role in Uganda's economy and rural livelihoods.
