This paper examines rice as one of the world's most critical staple crops, focusing on its global trade significance, environmental impacts, and evolving production trends. Drawing on agricultural, economic, and cultural sources, the paper addresses how increasing urbanization and population growth are driving demand for high-yield, low-cost rice varieties at the expense of regional diversity. It highlights water scarcity as the most pressing environmental challenge facing rice cultivation, discusses the social and historical dimensions of rice in cultures such as Japan, and considers how modern agricultural technology and market pressures are reshaping the livelihoods of small-scale growers worldwide.
Rice is one of the most important crops grown in the world. Many cultures — especially in Asia — rely on large quantities of rice every day to sustain life, supplemented with vegetables and, in better times, some meat. The cultivation of rice as a commodity is therefore an absolutely essential aspect of human sustenance. Rice becomes one of the most critical crops for the development of technology aimed at improving production, while also ensuring that mass production does not diminish nutritional value to the point that it can no longer sustain the millions of people who depend on it as their primary food source.
Rice can only be grown under specific conditions and often requires extensive acreage, large amounts of water, and a relatively high number of people to plant, maintain, and harvest it. This paper briefly discusses the ways in which technology and demand have changed rice production over the last several years, first by addressing several key case study questions and then by expanding the discussion to cover agricultural technology through topical research (WWF, "Agriculture and Environment: Commodities: Overview Rice," n.p.).
Rice is an essential crop utilized by a large majority of food consumers around the world. Unlike the United States and other Western societies, which subsist mainly on wheat-based products, consumers in Asia, Africa, and South Asia rely on rice as a staple crop that constitutes more than 50% of their diet.
As Smith and Dilday (2003) note: "Rice, Oryza sativa, also called paddy rice, common rice, lowland or upland rice — not including American wild rice, Zizania palustris L. — is the major caloric source for a large portion of the earth's population" (p. vii).
New demands on rice production are vast, making it a highly prized commodity with a rich history that is becoming far more constrained than it has been in the past, as increasingly urbanized cultures demand higher yields at lower prices. It is the demand for rice as a cheap food that is winning out over traditional varieties. Globally, the population of rice consumers is increasing at a rate of 1.7% per year compared to overall population growth of 1.3% (Khush, 2000, as cited in WWF, n.p.). Half of the world's projected population of 8 billion in 2025 will be rice consumers (WWF, n.p.).
Due to rice's increased demand and more limited production variety, it has become a commodity driven by a great deal of agricultural technology, including efforts to decrease labor requirements, increase yields, reduce variety, lower prices, and decrease the amount of water used in cultivation (Worldwatch, December 2007).
One of the most significant environmental impacts of rice production — particularly high-yield production — has been the over-utilization of water supplies. Water is a scarce commodity in many nations, even among some of the world's highest rice producers, such as India, where extensive drought has threatened its position in the global rice production and distribution market (Latham, 1998, p. 11). New technologies and programs are being developed and implemented to support higher yields with reduced water use (Worldwatch, December 2007).
Nearly one-sixth of the world's population — approximately 1.2 billion people — lack access to safe drinking water. Understanding the need for clean water and why it is plentiful or scarce in certain regions are core elements in the study of global health and wealth distribution (Smith, 2005, p. 307).
In a world where clean drinking water is increasingly scarce, and where modern agricultural technology relies heavily on herbicides, pesticides, and soil amendments to develop high-yield crops, water pollution has become an extreme concern (Greenhalgh & Faeth, 2001, p. 71). Changes have been implemented in many nations and agricultural centers, but in areas where agriculture is one of the only available means of livelihood, the issue is often secondary. Higher yields — especially given lower prices and higher demand — become simply an economic matter of supporting a household. Subsistence agricultural economies become trapped in situations where water quality is not the top priority, and the use of as many chemical amendments as can be afforded becomes the norm.
