  4. Why Rice?

  5. Rice as Universal Food Rice isthemostimportantdishfor more than a half of theworld’spopulation. UnitedNationsOrganizationdeclared 2004 as the International Year of Rice.

  6. National and International Rice Production In theyear 2009, 678 milliontons of rice wereproduced in theworld (FAO). Mexicoproduced 224 thousandtons of rice just in 2008 (SAGARPA).

  7. World’s Rice Consumption Per Person

  8. Rice Husk 100 g 20 g

  9. World Rice Production 170 millontons of rice husk in theworld (FAO) 56 thousandtons of rice huskproduced in Mexico (SAGARPA)
