- Library Collection RecordDrought is a normal experience for rangelands of the United States and poses one of the primary risks faced by managers and producers. Drought planning is therefore an important tool for minimizing…Publication Date 2018
- Library Collection RecordThe importance of rangeland basically comes from its environmental, economic and social importance. The secession of Sudan into two countries has remarkably reduced rangelands areas and shortened…Publication Date 2018
