Wadi Gaza (a priceless god gifted) is considered as one of the most important coastal wetlands located on the Eastern Mediterranean Basin, very rich in biological diversity (both flora and fauna). The wadi is also a station point for the migratory routes from north to south and from south to north. Wadi Gaza covers 3.5km of wetland. It is 7.5km in length and 20-50m in width. The wadi is located some fifty meters off the coastal plain of the shores of Gaza City on the Mediterranean. Wadi Gaza has the following characteristics:1.The largest part of the Wadi is dry. 2.The Wadi is susceptible to floods. 3.The Wadi has been adversely affected by urban growth. 4.Sewage and solid waste disposal has created a serious nature hazard in the Wadi. 5.Hunting birds and overgrazing are rampant. 6.Water drainage from the aquifer. 7.Pollution of the environment and the water source. The Wadi reflects special climatic conditions that make it one of the international centers for winter migration of various bird species along the southern Mediterranean. However, Wadi Gaza is fragmented. Dirt roads have split it; overgrazing has made it fragile, solid waste and wastewater have polluted it; and the effect of pesticide from adjacent agricultural land has destroyed its will life. No steps over the past 35 years were taken to mitigate the adverse effects on its ecosystem and biodiversity; no attempts were made to restore it from damage; no efforts were made to secure the allocation of water for the aquatic ecosystems; and no plans were made to promote its future rehabilitation, development or sustainability. Hopefully, within the course materials and participation, I can be able to improve our land sustainability concept and convey the message behind this e-training course.
