a bread-basket of southern Africa and a major exporter of bananas, coffee and sisal, but three decades of civil war (1975–2002) destroyed fertile countryside, left it littered with landmines and drove millions into the cities. The country now depends on expensive food imports, mainly from South Africa and Portugal, while more than 90% of farming is done at the family and subsistence level. Thousands of Angolan small-scale farmers are trapped in poverty. Transport Transport in Angola consists of: Three separate railway systems totalling of highway of which is paved 1,295 navigable inland waterways five major sea ports 243 airports, of which 32 are paved. Angola centers its port trade in five main ports: Namibe, Lobito, Soyo, Cabinda and Luanda. The port of Luanda is the largest of the five, as well as being one of the busiest on the African continent. Travel on highways outside of towns and cities in Angola (and in some cases within) is often not best advised for those without four-by-four vehicles. While reasonable road infrastructure has existed within Angola, time and war have taken their toll on the road surfaces, leaving many severely potholed, littered with broken asphalt. In many areas drivers have established alternative tracks to avoid the worst parts of the surface, although careful attention must be paid to the presence or absence of landmine warning markers by the side of the road. The Angolan government has contracted the restoration of many of the country's roads. The road between Lubango and Namibe, for example, was completed recently with funding from the European Union, and is comparable to many European main routes. Completing the road infrastructure is likely to take some decades, but substantial efforts are already being made. Telecommunications The telecommunications industry is considered one of the main strategic sectors in Angola. In October 2014, the building of an optic fiber underwater cable was announced. This project aims to turn Angola into a continental hub, thus improving Internet connections both nationally and internationally. On 11 March 2015, the First Angolan Forum of Telecommunications and Information Technology was held in Luanda under the motto "The challenges of telecommunications in the current context of Angola", to promote debate on topical issues on telecommunications in Angola and worldwide. A study of this sector, presented at the forum, said Angola had the first telecommunications operator in Africa to test LTE – with speeds up to 400 Mbit/s
