초록

고구마는 21세기 인류가 당면한 식량, 에너지, 환경, 보건문제 등을 해결하는 21세기 구원투수로 등장하고 있다. 고구마는 식량자원 뿐만 아니라 바이오에탄올, 기능성 사료, 항산화물질 등 고부가가치소재를 생산하는 생체반응기로 평가된다. 미국 공익과학단체(The nonprofit Center for Science in the Public Interest, CSPI)는 고구마가 저분자항산화물질, 식이섬유, 칼륨 등을 고함유하고 있는 고구마를 몸에 좋은 10대 슈퍼식품 가운데 하나로 선정하였다. 미국 농무부는 고구마를 전분작물 가운데 식량수급에 영향을 최소화하는 척박한 토양에 가장 적합한 바이오에너지작물로 평가하였다. UN 식량농업기구는 2050년에 세계인구가 97억 명이 될 것이며 지금 추세로 식량을 사용하면 2050년에는 지금의 1.7배의 식량이 필요하다고 전망했다. 어떻게 미래 식량위기를 극복할 것인가? 이러한 측면에서 척박한 토양에서도 어느 정도 수량을 보장하는 고구마가 지구가 당면한 제반 문제를 해결할 수 있을 것으로 기대된다. 본 논문에서는 세계 고구마 유전자원과 생산현황을 살펴보고, 글로벌 식량자원 및 고부가가치 바이오소재 측면에서 새로운 고구마의 북방로드 개척 및 상업적 대량재배를 위한 선결과제를 기술하고자 한다.

Sweetpotato [Ipomoea batatas (L.) Lam] represents an attractive starch crop that can be used to facilitate solving global food and environmental problems in the $21^{st}$ century. It can be used as industrial bioreactors to produce various high value-added materials, including bio-ethanol, functional feed, antioxidants, as well as food resources. The non-profit Center for Science in the Public Interest (CSPI) announced sweetpotato as one of the ten 'super foods' for better health, since it contains high levels of low molecular weight antioxidants such as vitamin-C, vitamin-E and carotenoids, as well as dietary fiber and potassium. The United States Department of Agriculture (USDA) also reported that sweetpotato is the best bioenergy crop among starch crops on marginal lands, that does not affect food security. The Food and Agriculture Organization (FAO) estimated that world population in 2050 will be 9.7 billion, and require approximately 1.7 times more food than today. In this respect, sweetpotato will be a solution to solving problems such as food, energy, health, and environment facing the globe in the $21^{st}$ century. In this paper, the current status of resources, and cultivation of sweetpotato in the world was first described. Development of a new northern route of the sweetpotato and its prior tasks of large scale cultivation of sweetpotato, were also described in terms of global food security, and production of high-value added biomaterials.
