its by 0.2 MT per ha during the same period. These changes in yields in Nigeria may be explained by<br />

the limited adoption <strong>of</strong> newly released varieties although this has happened only on a small scale.<br />

Although yields in Europe have shown some fluctuation, they have generally been much higher than<br />

those in Nigeria, Niger <strong>and</strong> other regions <strong>of</strong> the world. The yields in Asia <strong>and</strong> North America have<br />

also been higher than those in Nigeria <strong>and</strong> Niger for many decades. This may be an indication <strong>of</strong> an<br />

opportunity to increase yields to levels closer to what is obtained on other continents.<br />

Figure 5- 3: Trends in cowpea yields across the world 1970-2009<br />

Production<br />

Figure 5-4 shows that global cowpea production has steadily increased from an average <strong>of</strong> 1.3 million<br />

MT in the 1970s to about 4.5 million MT in the 2000s representing an annual average production<br />

growth rate <strong>of</strong> around 4.7%. With a production growth rate <strong>of</strong> 28.9%, North America saw the highest<br />

growth rate while the Caribbean recorded the lowest growth rate <strong>of</strong> about 0% with the 2009 production<br />

level being 60% <strong>of</strong> the 1970 level. West Africa recorded a growth rate <strong>of</strong> 4.9% while Asia <strong>and</strong> Europe<br />

recorded 5.9% <strong>and</strong> 7.9%, respectively. Since the 1970s cowpea production never exceeded 2% <strong>of</strong><br />

production <strong>of</strong> major legumes. Figure 5-4 indicates that soybeans, groundnut <strong>and</strong> thirdly beans have<br />

been the dominant legumes in terms <strong>of</strong> production levels. Soybean in particular has experienced very<br />

large increases in production since 1970 with an increase from about 40 million MT to about 220<br />

million MT by 2009.<br />

Of the 4.5 million MT average global production in the 2000s, Africa accounted for 95% (4.3 million<br />

MT). Asia <strong>and</strong> Europe accounted for 3% <strong>and</strong> 1%, respectively, while the rest <strong>of</strong> the world accounted for<br />

about 1%. Although North America has had the highest growth in cowpea production, its production<br />

share was not up to 1% in the 2000s.<br />

Although, Niger had the largest area under cultivation <strong>of</strong> 4 million hectares in the 2000s compared<br />

to the 3.8 million hectares cultivated in Nigeria, Niger’s production was much lower at just about<br />

770,000 MT compared to the 2.6 million MT <strong>of</strong> Nigeria. Among the factors that determine cowpea<br />

production at national level in West Africa are the level <strong>of</strong> technology, cost <strong>of</strong> input (price/unit) for<br />

cowpea production, prices <strong>of</strong> alternative crops, agro-ecological adaptations, <strong>and</strong> government policies<br />

(especially with regard to incentives aimed at promoting cowpea production).<br />
