into the Haud, an important grazing area for livestock. Somalia has only two permanent rivers, the Jubba and Shabele, both of which begin in the Ethiopian Highlands. These rivers mainly flow southwards, with the Jubba River entering the Indian Ocean at Kismayo. The Shabele River at one time apparently used to enter the sea near Merca, but now reaches a point just southwest of Mogadishu. After that, it consists of swamps and dry reaches before finally disappearing in the desert terrain east of Jilib, near the Jubba River. Environment Somalia is a semi-arid country with about 1.64% arable land. The first local environmental organizations were Ecoterra Somalia and the Somali Ecological Society, both of which helped promote awareness about ecological concerns and mobilized environmental programs in all governmental sectors as well as in civil society. From 1971 onward, a massive tree-planting campaign on a nationwide scale was introduced by the Siad Barre government to halt the advance of thousands of acres of wind-driven sand dunes that threatened to engulf towns, roads and farm land. By 1988, 265 hectares of a projected 336 hectares had been treated, with 39 range reserve sites and 36 forestry plantation sites established. In 1986, the Wildlife Rescue, Research and Monitoring Centre was established by Ecoterra International, with the goal of sensitizing the public to ecological issues. This educational effort led in 1989 to the so-called "Somalia proposal" and a decision by the Somali government to adhere to the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES), which established for the first time a worldwide ban on the trade of elephant ivory. Later, Fatima Jibrell, a prominent Somali environmental activist, mounted a successful campaign to conserve old-growth forests of acacia trees in the northeastern part of Somalia. These trees, which can live for 500 years, were being cut down to make charcoal which was highly in demand in the Arabian Peninsula, where the region's Bedouin tribes believe the acacia to be sacred. However, while being a relatively inexpensive fuel that meets a user's needs, the production of charcoal often leads to deforestation and desertification. As a way of addressing this problem, Jibrell and the Horn of Africa Relief and Development Organization (Horn Relief; now Adeso), an organization of which she was the founder and executive director, trained a group of teens to educate the public on the permanent damage that producing
