Vegetable Crops - definition Webster s definition of vegetable A herbaceous plant cultivated for food, the edible part or parts of such plants Vegetable Crops - definition Are Not: Cereal crops Sugar crops Pulse crops Woody fruit crops Are: Almost everything else 90+ economically important crops of various types and species 7

8 Vegetable Crops other features Generally cultured as annuals Mostly propagated from seed Many are insect pollinated Highly variable in climate and environment Most require intensive management Production acreage is usually small All are very important in the human diet Vegetable Crops PlSc 451/551 WHY are we studying vegetable crops? Nutrition Diet diversification Food security Because they are critical to betterment of the human condition Questions for Discussion What is projected for human population in the future? How will we feed all of these people? 8

9 Human Population Growth Thomas Malthus, An Essay on the Principle of Population: Geometric expansion of people 1x 2x 4x 8x 16x etc Linear increase in food supply Human Population Feeding the hungry masses North Korea (2 million deaths) Many areas of Africa Afghanistan One person in seven is chronically underfed Human Population Growth - Factors Dependable food production, transportation Rising incomes Improved housing and hygiene Medical advances Life expectancy in 1900: 47 years in 1998: 75 years 9

Human Population Growth UN Population Division predicts: Fertility will continue to decline to replacement in 2050 Life expectancy will continue to improve (HIV?) Overall population will level off at 10.5 billion people by

12 Human Population Growth Migration: The U.S. receives over 1 million immigrants a year Europe migrants from North Africa and Middle East From southern and eastern Europe to the western European nations Human Population Growth Migration: within countries common In developing nations in 1850, 11% of the population lived in the cities Currently, 84% of the population lives in urban areas Human Population Growth How do we increase food supply to match increasing populations? Increase amount of land in production. Increase the productivity of land already in use. Sustainability issues (Earth Summit II) 12

13 Human Population Growth Importance to a class in Vegetable Crops? Caloric needs versus Nutritional needs There is a shortage of food materials There is a shortage of food materials (fruits and veggies, tubers, root crops, nuts), which are the most important plant foods to supply humans with many of their nutritional needs: minerals, vitamins, proteins, starches, fats, and sugars. 13

14 Human Population Growth If the global community continues to work together to find ways to increase agricultural productivity and income sustainability, it will be able to meet the challenges of a growing world population while providing better, healthier life for all the world's citizens. Better agriculture unleashes economic growth, raises incomes and leads to smaller families. Lisa Rao Calypso Log 14
