	abstract = {Since 1971 there has been a revival of interest in the possibilities for cultivation of the true sago palm, Metroxylon spp. Agronomic and economic research shows that the palm can become an important starch producing crop. Many queries concerning the agronomy of the crop have been solved. The palm is especially suited to humid tropical lowlands. It is fairly salinity tolerant, but less tolerant to swampy conditions than generally thought. Research programmes to solve the remaining problems have been started in Sarawak on peat soils and will be started in Indonesia on mineral soils, both regarding the cultivated crop and exploitation of natural stands. Yields of 5 tons of dry starch per ha and year in the first year, increasing to 15 tons in the tenth, are to be expected in good quality natural stands under cultivation and on mineral soils. In new plantings there will be no yield in the first eight years; after that yields will increase rapidly to 25 tons per ha and year, tapering off slowly to 15 tons. Yields on peat soils under cultivation are expected to remain 25\% lower. In both natural stands and plantings an extensive drainage system is to be provided, which also allows the trunks, the raw material, to be floated out to the factory. Both systems of cultivation are expected to be economically viable with an internal rate of return estimated at 10\%.},

	abstract = {<p>This excerpt deals with specific native trees that can be found in the subdesert zones and their traditional environmental value. The specific species discussed are: Acacia albia, Acacia nilotica, Acacia senegal, Azadicachta indica and Conocarpus lancifolius. All, except for the Acacia senegal, rely on extraneous water supplies for adequate growth. The Acacia senegal relies on rainfall alone for its moisture.</p><p>Uses of these trees vary from conservers of soil to economic sources. One example of this is the Acacia albia, it is used mainly for fodder and refertilization of the soil. The Acacia nilotica is the most important species in the Sudan, because of is drought resistance. Gum extraction and fuel use are the economic functions of the Acacia senegal. This is one of the only trees that can be grown for economic purposes in subdesert zones. Each one fulfills a specific purpose in the Sahel.</p>},
