Know more about the Agricultural Project.
The agricultural sector is dominant in Uganda's economy. Whilst this sector grew at an annual average of only 3.7 percent over 1990-99 compared to the far more impressive growth of the industrial and service sectors, the importance of agriculture in Uganda's economy outweighs all other sectors put together. The agricultural sector employs 82 percent of the workforce, accounts for 90 percent of export earnings, and provided 44 percent of GDP in 1999. Moreover, the farmers in Uganda's 2.5 million smallholdings and scattered large commercial farms provide the majority of their own and the rest of the country's staple food requirements. Uganda is able to rely on agriculture due to the country's excellent access to waterways, fertile soils, and, (relative to many other African nations) its regular rainfall, although it does still suffer from intermittent droughts such as in 1993-94.
