 note = {Article, Tokar Delta is a name given to a small delta of approximately 161,000 hectares situated in the southern area of the Red Sea in Eastern Sudan. Beginning of 1980, mesquite species (Prosopis chilensis & Prosopis juliflora) were introduced to Tokar area to be planted as a shelterbelt for the city Tokar, but after while; it spread out to the delta area and became an invasive plant to the agricultural lands and along Khor Barak banks. Nowadays mesquite covers more than half of the delta area, decreased the cultivable land in the delta and created risk to the environment and livelihood of the people in the area. Therefore, this research study was an attempt to map and assess mesquite risk in the Tokar Delta and further provide guidance for possible solutions, control and management. The tools and methods used for the study were different multi-temporal satellite imagery, ground field survey and risk assessment models. The results showed that mesquite has increased by more than 50% during the period 1989-2001, while the expansion was about 10% during 2001-2013. Moreover, the assessment indicated that mesquite risk has many aspects ranging from management to environment and socio-economic.},
