It is currently cultivated on 10 million hectares, mainly in Central  and West Africa, but also in India, Australia, North America,  and parts of Europe. It was brought to the Americas on slave ships  and became a favorite of President George Washington, who was looking for a variety of peas\u2014he called them \u201cpease\u201d\u2014that could withst and the warm climates of the southern United States. Cowpeas are treasured for their high protein content (grains contain about 25 percent protein), leaves  and stalks that serve as especially nutritious fodder for cows (hence the name cowpea)  and other farm animals,  and the fact that their roots provide nitrogen to depleted soils. For many in Africa, the crop is a critical source of food during the \u201clean period\u201d\u2013-the end of the wet season when food can become extremely scarce in semi-arid regions of sub-Saharan Africa.\n\nThe many qualities of the cowpea are being discovered anew for a number of reasons. One is the potential of the cowpea\u2019s high protein content to help satisfy dietary requirements in food-challenged developing countries, particularly in Africa, where over 200 million people remain undernourished.\n\nCowpeas provide strong yields, even in hot  and dry conditions,  and scientists are developing ever more resilient varieties. And as climate change turns up the heat in sub-Saharan Africa, there is growing concern that production of current staples such as maize  and rice will fall or even collapse in some areas, requiring so-called \u201cclimate-ready crops\u201d like cowpeas to fill the void.\n\nIn addition, cowpeas can be used as cheap, high-quality animal feed. Today, livestock experts are drawn to the cowpea as they search for sustainable approaches to satisfying the fast-growing dem and for meat  and milk in developing countries. Scientists at IITA  and the International Livestock Research Institute (ILRI) say new \u201cdual use\u201d cowpea varieties bred to satisfy both human  and animal nutrition needs could be generating US$299 million to US$1.1 billion by 2020, given their potential to simultaneously boost livestock production  and reduce hunger.\n\nThe cowpea is also well-known for its ability to infuse soils with nitrogen, which again makes it a crop that could be enormously valuable to Africa, where many farmers struggle with nutrient-poor soils that are among the most challenging in the world.\n\nEven the National Aeronautics  and Space Administration (NASA) is on the cowpea b andwagon. With the plant\u2019s ability to produce nutritious leaves in only about 20 days, NASA scientists are considering sending cowpeas to the international space station, where they could be cultivated to provide food for astronauts.\n\nThis widely ranging  and rapidly intensifying interest will be highlighted at the World Cowpea Conference, where ground-breaking work in all aspects of cowpea production would be showcased.\n\nFor example, new research to be presented at the conference from researchers at IITA  and the University of California-Riverside focuses on the successful use of cutting-edge genome analysis tools  and techniques to probe cowpea DNA for genetic traits associated with prized qualities like drought  and disease resistance.\n\n\u201cWhen we can zero in on a particular place in the genome  and essentially point to the DNA that is providing the traits we want, the time it takes to breed improved cowpea varieties can be shortened from a decade or more to three years or less,\u201d said Fatokun, who specializes in cowpea genomics.\n\nScientists also will report on the latest developments in efforts to use biotechnology to borrow a gene from a soil bacteria, <em>bacillus thuringiensis<\/em> or Bt, to create a transgenic cowpea variety. The goal is to provide farmers with cowpeas that can fend off assaults from a caterpillar known as the <em>Maruca<\/em> or bean pod borer that routinely ruins entire fields. Researchers also will discuss endowing cowpea varieties with a gene from a common bean plant to provide protection infestations during storage.\n\nRelated discussions will focus on fresh research probing the risk of transgenic Bt cowpea spontaneously mating or \u201ccrossing\u201d with wild relatives\u2014wild cowpea is common in West Africa, which is a \u201ccenter or origin\u201d for the crop\u2014 and possibly creating a super weed that would be difficult to control.\n\n<strong>Sacking the Cowpea Beetle<\/strong>\n\nOne reason cowpeas are not as widely cultivated as corn or rice is that storage of dried peas is complicated by a tiny reddish-brown beetle, the cowpea weevil, that rapidly reproduces in traditional grain sacks  and renders the food inedible.\n\nIn Senegal, scientists from Purdue University in the United States  and Niger\u2019s Institute of National Agriculture Research will report on an effort to disseminate a simple storage technology to African farmers, which comprises a three-layer plastic bag that shuts off the oxygen required to fuel a weevil population explosion.\n\n<strong>Frittering Away to Financial Success  and Animating Seed Distribution<\/strong>\n\nOther research to be discussed at the conference focuses on the challenges of translating cowpea production into income  and how to encourage wider adoption of improved cowpea varieties along with better approaches to cultivation  and storage.\n\nFor example, researchers will discuss a new study analyzing the economic fortunes of hundreds of street vendors in Ghana  and Niger who sell a popular, deep-fat fried fritter made from cowpea batter called <em>kossai<\/em> ou <em>akara<\/em>. Most of the vendors are women,  and the researchers found that they tend to earn 4 to 16 times more than the prevailing minimum wage in their countries.\n\nMeanwhile, in another study, researchers will discuss an innovative effort that brings together scientists, linguists,  and 3-D animators to provide cowpea educational materials  and training programs for rural farmers.\n\n###\n\n<strong>About the World Cowpea Research Conference<\/strong> (<a href=\"http:\/\/cowpea2010.iita.org\/\" target=\"_blank\" rel=\"noopener\">http:\/\/cowpea2010.iita.org\/<\/a>)\nThe World Cowpea Research Conference is a gathering of international experts that, through sharing  and exchanging of knowledge  and ideas, aims to identify opportunities for cowpea growers to gain more incomes, enhance food security,  and attain robust health. The event is also targeted at increasing the public\u2019s awareness  and appreciation of cowpea, hopefully leading to more support for the cowpea scientific community to enable researchers to carry out cutting-edge research  and help realize the crop\u2019s potential. The conference is organized by IITA in cooperation the Institut Senegalais de Recherches Agricoles (ISRA), the Dry Grain Pulses Collaborative Research Support Programme (Pulse-CRSP),  and Purdue University.\n\n<strong>\u00c0 propos de l'IITA <\/strong>(<a href=\"https:\/\/iita.org\/fr\/\">www.iita.org<\/a>)\nAfrica has complex problems that plague agriculture  and people&#8217;s lives.
