Libya made no secret of its expansionist aims in an official road map published in 1970 by Studi Cartofici, Milano, via Sidoli 7, and distributed by Fergila Book­ shop. The legend of this map states that the interna­ tional frontiers as shown are not to be regarded as definitive, being liable to change. Moreover, in addition to the inclusion in this map of what is commonly known as the· "Aouzou Strip" in Libyan territory, there was in 1971 the actual ·military presence of Libya in Chad territory. This became par­ ticularly marked from 1973 onwards and has increased continuously since that time. The part occupied by Libyan troops before the inva­ sion of the whole of northern Chad constituted an area of 114,000 square kilometres. Now, in 1983, Libya occupies more than 150,000 square kilometres. It must therefore be emphasized that the term "Aouzou Strip" denotes a much smaller area than is· occupied by Libya. Libya is actually occupying the entire sub­ prefecture of Tibesti. JI. UNACKNOWLEDGED REASONS FOR THE OCCUPATION OF TiBESTI A glance at· the first part of Tibesti occupied by Libyan troops would show that it corresponded exactly to the line drawn by the stillborn Laval­ Mussolini Treaty of 7 January 1935 (annex VII, below), which clearly has no legal existence. Libya has now nibbled away more territory, following the with­ drawal of its troops from N'Djamena in 1981. As though by chance, this zone, which lies between the 20th and 24th degrees of latitude north, harbours vast strategic mineral resources: uranium, wolframite, copper, zinc, lead, silver, tin, graphite, cassiterite, beryl, mispickel, gold, tungsten. Everyone knows the strategic, scientific and eco­ nomic importance of these resources. The question is why a country as rich as Libya should covet the re­ sources of another, notoriously poor country like 
**Analysis**
The text appears to be discussing the territorial expansion of Libya, its military presence in Chad, and the strategic mineral resources in the occupied region. The author is questioning the motivations behind Libya's actions, suggesting that it may be driven by a desire to access these resources. The text does not mention economic development, agriculture, forestry, fishing, industry, transport, communication, health, education, employment, humanitarian aid, or culture. It seems to focus primarily on natural resources and international relations.
