Abstract/Description: | The world's population has more than doubled in the last half century, reaching 6 billion in 1999, and is projected to grow to 9.3 billion by the Year 2050. As a consequence of more people on this earth that need to be fed, in addition to rising incomes in some countries, the demand for food is expected to increase by 50% by 2015 and to more than double by 2050.1t is this grim reality that agriculture as a profession faces-the challenge has to be met by everyone involved in the food production chain, from researchers to farmers, and all in between. Today, the world's population is better nourished than any time in history. The advances in global food production in the 20th century have dispelled, at least temporarily, the dire predictions of Malthus. Yet, despite such achievements, poverty and malnutrition, and their associated societal consequences, are the lot of numerous people in developing countries, especially in Africa and Asia. In assessing modem agricultural practices and technology, it is important to distill both the limits and potential for sustaining global food supplies without degrading the resource base. Over the past three decades, expansion of irrigation, highyielding varieties, and fertilizer input have been the major factors in achieving selfsufficiency in food grain production. On a worldwide basis, agriculture accounts for about 70% of all annual water withdrawals, and significant areas of irrigated lands are degraded to some extent by waterlogging and salinization. Another major pressure that leads to declining irrigation is high energy costs associated with delivering water to crops. With burgeoning populations, renewable fresh water resources are subject to severe competition between agriculture, industrial, and residential uses. Demand is increasing for all these uses. The shift of water from agriculture to urbanized societies and industry may hinder future global food production. Given the pressure on the world's ecosystems, dryland agriculture, a sector that has been neglected in the past, will be increasingly important in meeting food requirements in the future. Globally, 90% of cropland is classified as dry land, and these lands provide 67% of all crop production and about half of the economic value of all crops. However, it is estimated that more than two-thirds of the potentially productive drylands are threatened by various forms of degradation. Therefore, it is essential that appropriate production technology be developed in the future to protect the fragile dry lands in the process of meeting the needs of world's future population. |
