Agricultural productivity in the region is far below potential. Although productivity has increased in recent years within Southern Africa, most of the growth has come from bringing previously unculti- vated land into production, rather than from inten- sification made possible by technical change. Southern Africa offers attractive opportunities for regional research. Groups of countries within Southern Africa share similar agro-ecological zones and farming systems, suggesting that there is potential for finding shared solutions to common problems. Although technology spillover is already occurring within the sub-region, significant poten- tial remains for expanding spillovers.
