" At risk are vital genetic resources for resisting drought, pests
ROME, ITALY (22 May 2007) -- Wild relatives of plants such as the potato and the peanut are at risk of extinction, threatening a valuable source of genes that are necessary to boost the ability of cultivated crops to resist pests and tolerate drought, according to a new study released today by scientists of the Consultative Group on International Agricultural Research (CGIAR). The culprit is climate change, the researchers said.
According to the study, in the next 50 years as many as 61 percent of the 51 wild peanut species analyzed and 12 percent of the 108 wild potato species analyzed could become extinct as the result of climate change. Most of those that remained would be confined to much smaller areas, further eroding their capacity to survive. The study also examined wild relatives of cowpea, a nutritious legume farmed widely in Africa. It found that only two of 48 species might disappear. However, the authors predict that most wild cowpeas will decline in numbers because climatic changes will push them out of many areas they currently inhabit. "
