African seed producers and researchers have called on policymakers to boost production of improved seed varieties and ensure that they are released to farmers more quickly.

At a policy workshop held in Abuja, Nigeria, stakeholders from industry and academia sought to unify the seed laws of different countries within West Africa to narrow the gap between supply and demand.

Recent studies by researchers at the International Institute of Tropical Agriculture (IITA) and the International Maize and Wheat Improvement Center (CIMMYT) show that current demand for improved varieties of maize seeds far exceeds supply in the region.

According to one study, the average supply of drought-tolerant, improved maize seeds in the region accounted for only one third of the total demand- with less than 50 per cent in Nigeria and only 11 per cent in Ghana - from 1997 to 2007.

Tahirou Abdoulaye, an IITA agricultural economist who led the study, said that maize seed production in the region is too low and called for a favourable policy framework to attract the private sector to the seed industry.

According to an IITA press release, maize productivity has been under threat from both climate change-related drought and delays in getting improved seed varieties to farmers.

Solving the latter problem requires a more effective, streamlined seed sector, said Wilfred Mwangi, associate director for Africa in CIMMYT's Global Maize Program.
