A more efficient, cost-effective approach would be an internationally coordinated, secure system that holds a base collection and one or two duplicates at key sites. This should not be a disincentive for any country to manage its germplasm properly, but is an acknowledgement of the practical reality of many countries’ financial and technical difficulties in developing secure systems. Varietal development New cultivars have long benefited both large and small growers. Specifically targeting benefits to small and medium resource-poor farmers, however, is a possible option for cassava programmes.

0%. Land use is also low with only about 25% of the total area in agriculture. vp Monday, February 04, 2002 11:21:41 AM Color profile: Disabled Composite Default screen 22 G. Henry and C. Hershey Nevertheless, the area planted to cassava and production have been relatively stable in the past 35 years. This reflects the fact that most farmers who rely on cassava do not have many other options for income. Most of the growing areas are drought-prone (coastal) or have acid, low-fertility soils (savannah and rainforest).

Despite this emphasis on technology, yield levels have been disappointing – some of the lowest in the region. This is partly because cassava is being grown on the poorer soils, and there is a shortage of inputs. Fertilizers and herbicides are increasingly diverted to higher value crops. Cuba’s research and extension system has been among the most consistently productive in the region, with a long-term, well-balanced interdisciplinary effort. The programme has developed packages of agronomic practices, new cultivars and pest control systems.
