The economy of Lesotho is divided into 3; primary, secondary and tertiary sector. The primary sector comprises of agriculture and mining and quarrying sectors. Activity in the agriculture sector is mainly at the subsistence level and efforts to commercialize the sub sector have been intensified. The mining and quarrying sector, (which is mainly sandstone and diamonds) has shown potential for growth since 2005 and has been increasing significantly until 2011. The limited growth to date has been due to some refurbishment of equipment by one of the three mining companies and a decline in the existing production. The secondary sector comprises of manufacturing, building and construction. Manufacturing sector surpassed the Government as the largest employer in 2012 and its contribution to GDP is significant. Building and construction is one sector that has currently shown potential for better performance. Private sector is actively participating in this sector and it provides a good platform for promoting property development to support industrial development. Lastly, the tertiary sector which comprises of the retail sector, telecommunications, real estate and government is another significant contributor to GDP. In telecommunications, an increase in the number of service providers brought about expansion of products, access to services and better service delivery. The rest of the components have been increasing consistently.
