Guban
Guban, meaning "burnt" or "burned," is a vast coastal plain in the Republic of Somaliland, stretching between the Awdal and Sahil. It runs parallel to the Gulf of Aden for about 240 km, from Seylac in the west to Berbera in the east. The plain narrows gradually from approximately 56 km in the west to about 6 km in the east. Guban is sandy, low-lying, and lies mostly under 100 meters above sea level. The region experiences high temperatures, humid conditions, and minimal rainfall, averaging around 50 mm per year. Vegetation is sparse, mainly consisting of steppe plants. Seasonal rivers cross the plain, which gradually rises toward the Galgodon Highlands to the south, reaching approximately 1,980 meters in elevation. Ecologically, Guban lies within the Djibouti xeric shrublands, a semi-desert ecoregion along the southern Red Sea and northern Gulf of Aden coasts.
Etymology
The term Guban derives from the Somali root gub, meaning "to burn" or "to scorch," a reference to the region's extreme heaClimate and Hydrology
Climatically, the Guban is a dry and sparsely vegetated zone that receives limited and irregular rainfall, mainly during the relatively cooler months between October and March. Despite its aridity, the landscape is crossed by numerous tugs, which indicate occasional flooding caused by heavy rains in the adjacent highlands. These episodic floods recharge subsurface water reserves, making groundwater accessible through shallow wells dug beneath the sandy soil, and allowing limited human and animal habitation in the region.Geography
Northwestern Somalia is geographically divided into three main regions: Guban, Ogo , and the Haud. Guban forms the coastal lowlands in the northwest, the Ogo constitutes the central plateau to the south of Guban, and the Haud forms the southern tip of northern Somalia near the Ethiopia-Somalia border in the northwest.The Ogo highlands rise as a series of mountain ranges extending from the escarpments that border the Guban to the Ogaden frontier, and running roughly parallel to the northern Somali coast as far as Cape Guardafui. The highest elevations occur along the escarpment edge, reaching approximately 2,400 metres in the Erigavo area. Rainfall increases with altitude and, particularly in the western highlands, is sufficient to support limited agriculture. Overall, the Ogo highlands are relatively well watered throughout much of the year. Further south, the highlands gradually descend into the Haud Plateau, an extensive semi-arid region that forms one of the principal grazing zones of northern Somalia. The Haud is characterized by red soils and the absence of permanent surface water; however, following the rainy seasons, it becomes covered with tall grasses that provide valuable pasture, especially for camels. The plateau is intersected by shallow valleys and natural depressions which temporarily hold rainwater, forming seasonal pools that persist for several months before drying out.
