Reports a concerted interinstitutional attempt to generalize the use of the available draught animal power for the construction of more effective soil surface drainage. The hypothesis is that the relatively high productive potential of the Ethiopian highland vertisols, particularly in high-rainfa...

African animal trypanosomosis constrains agricultural production in areas of Africa that hold the continent's greatest potential for expanded agricultural production. Previous studies indicate that the incidence of trypanosomosis: (i) reduces calving rates by 1-12 percent in tolerant breeds and b...
