farms. The skills they brought, combined with general economic liberalisation under the late Zambian president Levy Mwanawasa, has been credited with stimulating an agricultural boom in Zambia. In 2004, for the first time in 26 years, Zambia exported more corn than it imported. In December 2019, the Zambian government unanimously decided to legalize cannabis for medicinal and export purposes only. Energy In 2009, Zambia generated 10.3 TWh of electricity and has been rated high in use of both solar power and hydroelectricity. However, , Zambia began experiencing a serious energy shortage due to the poor 2014/2015 rain season, which resulted in low water levels at the Kariba dam and other major dams. In September 2019, African Green Resources (AGR) announced that it would invest $150 million in a 50 megawatt (MW) solar farm, along with an irrigation dam and expanding the existing grain silo capacity by 80,000 tonnes. Culture Prior to the establishment of modern Zambia, the inhabitants lived in independent tribes, each with its own way of life. One of the results of the colonial era was the growth of urbanisation. Different ethnic groups started living together in towns and cities, influencing each other's way of life. They also started adopting aspects of global or universal culture, especially in terms of dressing and mannerisms. Much of the original cultures of Zambia have largely survived in rural areas, with some outside influences such as Christianity. Cultures that are specific to certain ethnic groups within Zambia are known as 'Zambian cultures' while those lifestyles that are common across ethnic groups are labelled "Zambian culture" because they are practiced by almost every Zambian. In the urban setting, there is a continuous integration and evolution of these cultures to produce what is called "Zambian culture". Zambia practices several ceremonies and rituals ranging from nationally recognised traditional ceremonies to unrecognised yet important ceremonies. Many of the ceremonies and rituals are performed on special occasions celebrating or marking achievements, anniversaries, the passage of time, coronations and presidential occasions, atonement and purification, graduation, dedication, oaths of allegiance, initiation, marriage, funeral, birth ceremonies and others. Like most African countries, Zambia practices both disclosed and undisclosed ceremonies and rituals. Among the disclosed ceremonies and rituals include calendrical or seasonal, contingent, affliction, divination, initiation and regular or daily ceremonies. Undisclosed ceremonies include those practiced in secret such by spiritual groups like Nyau and Nakisha dancers and traditional marriage counsellors
