  1. “Rice” A Cradle to Grave Analysis Erick Mendoza MW 10:10-11:50 Race, Poverty, and the Environment Professor Raquel R. Pinderhughes, Urban Studies Program, SFSU Public has permission to use the material herein, but only if Erick Mendoza, Urban Studies 515, SFSU, and Professor Pinderhughes are credited.

  2. This presentation focuses on Rice. It is designed to describe the cradle to grave lifecycle of Rice, paying particular attention to the social, environmental, and public health impacts of the process associated with the production of Rice. Rice has been promoted as the cure to hunger in these regions, this analysis explores the impacts of such claims to the farmer, consumer, and environment. IRC 2003:1908

  3. Why Rice? • Four-fifths of rice produced is consumed by small-scale farmers in most developing countries. • Alone it supplies over seventy percent of their daily calories/protein intake. • Along with grains such as wheat and maize it is consumed by 5.6 billion people world wide. That is four-fifths of the world population. • Unlike wheat and maize 80 percent of rice is consumed by people. • It contains large amounts of calories, high protein content, it has high utilization process (vitamin digestion and absorption). • It contains vitamin A, zinc and iron. IRRI 2003a:1

  4. IRC 2003:1911 IRC 2003:6323

  5. Other uses for Rice: • Waxy rice are used for desserts and as salad dressings. • As baby food, breakfast cereals, rice breads, beer, wines. • As rice paper. Juliano 1985:14 IRC 2003:2305 IRC 2003:2305

  6. The hulls and excess tillers (stems) are used as feed, compost for the fields, for fuel. Juliano 1985:14 IRC 2003:18433 IRC 2003:18446

  8. Rice Cultivation • Rice is cultivated and eaten mostly in the “rice bowl” region, which consists of Asia and middle/near east countries. Juliano 1985:15 IRC 2003:31222 IRC 2003:154888

  9. Rice has been cultivated in these regions for over nine thousand years, which means that it is highly variable and adaptable. Its been grown in the lowlands of India to as high as three thousand meters in Nepal. Lang 1996:5 IRC 2003:18437

  10. It just needs enough water and solar energy to be cultivated in most places. Lang 1996:5 IRC 2003:2326

  11. Rice has been cultivated mostly in tropical areas because it lives in water. • Every stage of its growth, it is immersed in water. • Most rice are cultivated and consumed by small-scale farmers and local communities. • Their planting season begin in a month before the monsoon season, usually in May. • They plant the seedlings in irrigated paddies, lowland marshes, or near river beds. • After one month or so the seeds germinate and begin to grow, they then transplant them to larger fields, where they are matured. • The process lasts about 100-120 days. Mutters 1998:1

  13. “The Green Revolution” • Leading scientists postulated in the 1950s that the world population will grow exponentially and feeding them will be one of the main issues that will entail the population boom. • The International Rice Research Institute was subsequently founded by the Rockefeller Foundation along with the Ford Foundation. And with their success other research organizations had been spawned: The International Rice Commission, Food and Agricultural Organization, United Nation Development Program to name a few. Lang 1996:xiv

  14. IRC 2003:2321 IRC 2003:2317

  15. Researchers proposed that in order to increase yields as well as the quality of the rice, they needed to: • Cultivate rice that has shorter tillers (stems) to combat the torrential downpour common in these regions. • Be resistant to pests. • Robust enough to handle cultivation. • Have an earlier maturation stage, achieve better irrigation methods. Lang 1996:xi, Juliano 1985:11 IRC 2003:2958

  16. For the most part they were successful in their goals: • They increased the yields annually from 203 million tons to 479 millions tons by the nineties. Lang 1996:9 • They produced rice that has higher nutrient contents such as IR6884 and IR72, which contains higher zinc and iron. IRRI 2003a:4 • They also have been able to introduce direct seeding methods that help reduce the cultivation time from 190-220 days to 100-120 days. Lang 1996:3

  17. They were able to produce hybrid rice that could withstand the monsoon season, have shorter tillers, and be able to yield more grain.Juliano 1985:11 IRC 2003:2384 IRC 2003:25244

  18. The Aftermath: environmental and social effects • With all their accomplishments there have been set backs. • Mono-culturing was emphasized thus depleting the nutrients in the soil. FAO 2003:5 • The crops became very susceptible to pests such as insects, weeds, and fungus. Rola and Pingali 1993:17 • The overuse of pesticides, herbicides to combat these pests. And the misuse of fertilizers. Rola and Pingali 1993:23 • The stagnation of rice production today, along with the marginalization of the local farming community. Mutters: 1998:1

  19. The most important environmental issue that concern rice production today is the improper use of pesticides, herbicides and fertilizers to help increase yields. IRRI 2003a:4 • The pesticides used in combating rice pests are some of the most toxic in agrochemicals; most are banned in the U.S. Rola and Pingali:199338 IRC 2003:24777 IRC 2003:2387

  20. Insecticides such as Methyl parathion are commonly used because they are cheaper but are classified as one of the most toxic by the WHO. • It interferes with the normal functioning of the brain and nerve cells. • Exposure to very high levels of methyl parathion for a short period in air or water may cause death, loss of consciousness, dizziness, confusion, headaches, difficult breathing, chest tightness, wheezing, vomiting, diarrhea, cramps, tremors, blurred vision, and sweating. USDHS 2001:2,3

  21. Farmers are commonly unaware of the effects of these chemicals on themselves as well as others they come into contact with. • They normally wear minimal protective gear when spraying. • They lack the knowledge of proper interval time before reentering the sprayed areas. Rola and Pingali 1993:38 • They store the chemicals improperly: in their homes near food, areas where anyone has access to them, and they dispose the containers in piles near their farms where they leach into the ground and affect the water base. FAO 2003:3,4, Maranan and Rapusas 2000:2,3

  22. Further the overuse of pesticides, herbicides, and artificial fertilizers leaches into the ground water effectively contaminating it. • High levels of nitrates in drinking water can cause health problems such as stomach pains, cholera, and hepatitis. • High nutrient content in water are toxic to aquatic life by encouraging rapid growth of algae, which depletes the oxygen in the water thus suffocating fish and other aquatic life. FAO 2003:2,3 • The arability of the land is also affected. • Soil salinity is affected by mono-cropping and depletes the soil fertility • Makes the soil too acidic for crops. • The soil structures are altered and are susceptible to erosion. FAO 2003:5,6

  23. Contemporary Issues: • Development in production methods to help curtail the stagnation on current yields: • The re-introduction of crop rotation in order to increase yields. • Methods in reducing the lost of yields in the post production process. FAO 2002:1 • Research in genetic development of rice to increase yields as well as their nutrient contents. ISS 2003:2 IRC 2003:3022 IRC 2003:1917

  24. Data today shows that mono-culturing of rice has stagnated the production of rice. Further, along with pesticide use, it has increased rice’s susceptibility to insects due growing resistance against the pesticides by the insects through mutation and the “survival of the fittest” of the insects. Rola and Pingali 1993:17 • Researchers are now trying to incorporate crop rotation in order to decrease these effects, which were overlooked at the genesis of the “green revolution.” Maranan and Rapusas 2000:6, FAO 2002:1

  25. IRC 2003:2319 IRC 2003:2421

  26. Although the possible losses are tremendous in the cultivation of rice due to the unpredictable impact of nature, the majority of losses are actually at the postproduction level process. • The losses are about 30 percent and are attributed to operational, technical, socioeconomic, cultural, political and environmental factors. Maranan and Rapusas 2000:5 • Dealing with these issues are now part of the discourse in improving the yields of rice for the future.

  27. IRC 2003:2737

  28. The most volatile issue that concern rice production and research today is the genetic alteration of the composition of rice in order to add nutrients and resistance to pests. • Instead of hybridizing different kinds of rice, researchers now are attempting to genetically alter their composition, which has had its success but ultimately have been mired in problems with such rice. ISSI 2003:2 • It is also very costly: financially as well as environmentally. • The concentration of research and development by bio tech industries. ISS 2003:1

  29. Bio tech firms are funding these research projects and are monopolizing the outcomes. • They patent the seeds, making them inaccessible to those who really need them. • By the time they are at the finished stage they are very costly, billions of dollars are funded into their research. FAO 2002:1,2 • The potential environmental effects are grave according to data on the research so far. • They contaminate other crops. • Have been proven to be toxic in humans. • High contents of vitamin A can cause abdominal pains, nausea, vomiting, hair loss, weight loss. • Herbicides infused with rice are harmful; glufosinate was added to rice and was found that it caused birth defects, behavioral changes, cleft lips and skeletal defects, and miscarriages. Jack 2003a:3

  30. Rice is the most important crop cultivated in the “rice belt” region. For that reason, I feel that current research on developing and altering the composition of rice by genetic modification be hindered and the development and improvements in traditional ways of integrated farming be put at the forefront of discussion. Because there are evidence that the current methods and applications are not surpassing the advancements achieved during the “green revolution.” Further, the mishaps of the revolution should be addressed. • I also want to add that there are aspects of the production process that I did not cover in detail because of the magnitude of the research.
