The Yemen Arab Republic (YAR) is a contrasting land of cool, rainfed highlands and hot, dry slopes and lowlands. This report profiles the environment of the YAR, highlighting water pollution and scarcity, as well as soil erosion and salinization. Contamination of drinking water is a serious problem in both urban and rural areas. Inadequate sewerage systems pollute aquifers beneath city areas, while in rural areas, much of the wellwater contains unacceptable levels of dissolved nitrates, chlorides, and salts. Water scarcity is a related concern. There is little surface water in Yemen and groundwater is being depleted by increased irrigation pumping. Water demand in the cities of Sana'a and Ta'izz is expected to outstrip aquifer supply by the end of the century. Soil erosion is a problem in Wadi areas, which historically have been subject to heavy flooding which damages irrigation systems and erodes soils. Abandoned terraces are eroding in the highlands, while overexploitation of vegetation in woodland and range areas has made soil erosion of concern even in nonagricultural areas. The use of saline surface and well water for irrigation has led to mounting soil salinization, espec
