Rice Today January-March 2008
C yclone Sidr smashed into the south-ern coastal districts of Bangladesh
on 15 November, killing almost 4,000
people and leaving millions homelessand short of basic staples such as rice.Based on initial estimates, about 1 mil-lion hectares of rice are affected.
The cyclone and two major oodsearlier in 2007 have contributed tomajor food shortages in the South Asiancountry, which was added to a list of 37countries facing a food crisis and re-
quiring external assistance, publishedon 17 December 2007 by the Food and
Agriculture Organization (FAO) of theUnited Nations.
According to the FAO, the liveli-hood of more than 8.5 million peoplehas been adversely affected by the
cyclone damage. Estimates of the riceshortfall caused by the cyclone and
oods range from 1.4 million to 2 mil-lion tons.
The country’s food-grain imports—usually 2 million to 2.4 million tons—are likely to rise to around 3.5 million
tons in 2008. Adding to the burdenfor the millions of aficted people, theincreased imports combined with highglobal grain prices will probably lead to
higher prices for consumers.To see what role IRRI might play
both in response to this disaster andto mitigate the effects of future cy-clones—predicted to occur with greater
frequency and severity due to climatechange—Institute scientists Zainul
Abedin, Abdelbagi Ismail, and DavidJohnson traveled to the affected areasof Bangladesh on 14-16 December.
They were joined by the BangladeshRice Research Institute (BRRI) andseveral nongovernmental organizations
working on the IRRI-coordinated Food
Security for Sustainable HouseholdLivelihoods (FoSHoL) project.
“Farmers in affected areas are inimmediate need of relief efforts to cope
with the current devastation,” said Dr.
Ismail. “Short- and long-term measuresare needed to ensure sufcient seedsupply for these farmers, particularly for 2008. This is because most farmerslost their rice crop and the grain yield
of the remaining crop is expecte d to be very low, and will mostly be c onsumed
within a few months. Besides, seedsare of low quality and cannot be storedfor the next transplanted aman [wet]season.”
Farmers were unsure of how they
would meet their food needs up to theirnext season’s harvest, 4–5 months away at the earliest. Crops that were able to
be harvested tended to produce small
yields of poor-quality grain that, ac-cording to farmers, tastes bitter. Many families lost everything—not only rice but also their houses, personal
belongings, vegetables, poultry, and
livestock. With BRRI and FoSHoL collabo-
rators, the IRRI scientists developedpreliminary recommendations forrestoring farmers’ livelihoods. These
included provision of seeds of suitablerice varieties in the short term and, inthe longer term, the development of new varieties and crop management
and intensification strategies to in-crease the chances of crops survivingfuture severe weather events.
On 17 December, Drs. Abedin,Ismail, and Johnson, along with IRRI
liaison scientist Hamid Miah, discussedtheir observations at a series of meet-ings with the secretary of the Ministry of Agriculture, Md. Abdul Aziz, theBangladesh Agricultural Research
Council, and the Bangladesh Rural Advancement Committee.

ey factor in high yields
onger grain-lling duration in tropicalrigated rice is a major factor in higherelds. This was a key conclusion of
study reported in the 26 November007 issue of Field Crops Research.he paper, Grain-filling duration,crucial determinant of genotypic
riation of grain yield in eld-grownopical irrigated rice, authored by e Korean National Institute of Cropience’s Woonho Yang et al, was based
n research by a team that included
veral IRRI crop scientists. The teamtermined that longer grain-filling
uration provided rice plants with more
cumulative mean temperature andcumulative solar radiation throughoutthe grain-filling period, leading tohigher grain weight per unit area. The
study also found that grain-lling rateand duration were highly genetically
variable traits, that grain weight wasnegatively or not signicantly associated
with grain-lling rate, and that grain-lling rate and duration were negatively correlated with each other.
Rice vaccine for hepatitis? A group of Chinese scientists hasdeveloped a transgenic rice line thatcould offer a hepatitis B virus (HBV)
vaccine. Rice was chosen because it isa staple in many developing countries
where HBV causes severe problemsand large numbers of people do not
have access to existing vaccines. Theresearch team introduced to rice agene known as SS1, which codes for anHBV surface protein. When given to
mice, the SS1 protein stimulated theproduction of antibodies that providedprotection against hepatitis infection.The researchers, who reported thestudy in the 20 September 2007 issue of
Transgenic Research, hope to developan oral vaccine for preventing hepatitisinfection in humans.
Rice diseases as bio-weapons
Microbiologists in the United Statesare, according to a story in the 29November 2007 issue of Nature,
expressing concern about a governmentproposal to limit research on severalplant pathogens because of theirpotential to be used as bio-weapons.
The researchers say that the plan tosubject rice and citrus disease agents tothe same restrictions as Ebolavirus andanthrax are ill conceived and will limitthe response to a natural outbreak. The
U.S. Department of Agriculture plansto add four plant pathogens to thegovernment’s list of “select agents,”
created to keep infectious diseases outof the hands of would-be terrorists.
Slaves brought U.S. rice?
Preliminary research reported in National Geographic News suggeststhat a rice variety grown successfully
by many colonial plantation owners was
brought to the United States from West Africa. If conrmed, the nding suggeststhat African slaves are responsible fornot only working the farms and bringingthe knowledge to grow rice but also for
supplying the variety itself, which wasone of the most lucrative crops in e arly
American history. West Africans grew
varieties of rice for several years before the start of t he s with the colonies.

n the face of growing pressureon one of Asia’s most important
od production systems, experts arearning that farmers must get morelp to make them more efcient.
Irrigated rice production provides
pproximately three-quarters of e world’s rice needs, and has a
articularly important role to play
w, with international rice prices at a-year high and global stocks at a 30-
ar low. However, at the 3rd Steeringommittee meeting of the IRRI-ordinated Irrigated Rice Research
onsortium (IRRC), more than 50 riceientists from 13 countries highlighted
e problems facing farmers of irrigatedce. The meeting, held on 8-9 October007, was hosted in Hanoi by theietnamese Academy of Agricultural
iences.Major issues discussed included
mpetition for land and water fromdustrial development, the increasedigration of farm laborers to cities, t he
emergence of rice pests and diseases,
and the increasing costs of productionand inputs. In Vietnam alone, industrial
development has caused the loss of 300,000 hectares of irrigated rice landin the past 5 years.
On a positive note, research
efforts to help rice farmers boosttheir production efficiency and reinin their costs are being helped by new
scientific knowledge in several key areas, including new technologies
to optimize the use of fertilizers andreduce water use.
The IRRC, with major supportfrom the Swiss Agency for Developmentand Cooperation, promotes and
s u s tai ns p ar tners hi p s betweennational agricultural research andextension systems and IRRI to helpfarmers achieve increased protability,
food security, and environmentalsustainability. The Consortium operatesin the Philippines, Bangladesh, China,Cambodia, India, Indonesia, Laos,Malaysia, Myanmar, Sri Lanka, and
Vietnam.

He writes: “I was sittingat my piano, looking at the cover, seeing the rugged landscape rollingdown onto a narrow river, a temple, shoals, and mud; nevertheless, thesame river that later calms down on its voyage through Cambodia andbeyond. So, I began to play an impression of the scene. After an hourI had a piece that runs for nearly 4 1/2 minutes.” He calls it, naturally,River of Rice.

R ice prices will continue to increase,according to participants at the
World Rice Commerce Conference
held in Bali 31 October–1 November2007. According to Randy Barker, headof IRRI’s Social Sciences Division,
who represented the Institute along
with Development Director DuncanMacintosh, “No one was selling and itseemed generally assumed that the new crop was already sold.”
Jeremy Swinger, from Farm and
Trade Inc., in his presentation onGeneral trends in the commoditymarkets, looked at the t ight situation forall food stocks, especially rice, wheat,
and maize. Mr. Swinger sees the currentprice increases as not just a short-termphenomenon but a fundamental shift in
the grains markets.Bob Papanos, who publishes The
Rice Trader , focused on the near term,projecting export supplies for thecoming year. He suggested that prices
would continue to rise steeply, peakingin February to March 2008.
Delegates noted that recentincreases in production have beenhighest in the delta areas of Southand Southeast Asia—particularly
Bangladesh, a major importer, andThailand, Vietnam, and India, whichhave been a source of major exports.Exports have been rising with theincrease in exports to sub-Saharan
Africa coming largely from India and
Pakistan. However, with the exceptionof Cambodia and Myanmar, it appearsthat the production increases in the
deltas have reached a limit.The current trade situation was
brought to a head by India’s 9 Octoberdecision to ban exports, suggesting
a desire to maintain domestic stocksand stable rice prices. Whether and
when India will again become a majorexporter is uncertain.
“The conclusion is that prices will
rise—how far, how fast, and for how long is anyone’s guess,” said Dr. Barker.“Then the question is how the price r ise
will affect supply response in Asia. Sub-
Saharan Africa is likely to experiencethe sharpest reduction in imports. It isdifcult to ship to Africa because of high
freight costs and poor port facilities,and India and Pakistan have been two
of the main suppliers. Adding to the woes of the African importers is the very sharp rise in Pak Irri and Thai A1 Super(see gure) low-quality grades favored
by most African countr ies.”
There was speculation on
the situation could be reverse were to again export in 2008
were to draw down stocks. The was that this may stave off highfor 2008 but not in the long ruclear sign of where future incsupply will come from.

Risotto is a traditional Italian rice dish. This recipeserves 4 as an appetizer.
Ingredients60 ml olive oil 1 onion, nely chopped
2 cloves garlic, thinly sliced200 g risotto rice (e.g., arborio orcarnaroli)1 liter warm vegetable stock120 g rozen baby peas¼ cup loosely packed mint leavesFinely grated parmesan to serve
PreparationHeat olive oil in a large saucepan, addonion and garlic, and sauté over lowheat or 8 minutes or until onion is sotand translucent. Add rice and sauté
over medium heat or 5 minutes, thenadd a little stock and stir until stockis absorbed. Continue to add stock,stirring until rice is al dente (rm butnot hard). Next, add peas and mint andcook or 2 minutes or until peas aretender. Season to taste with salt and
reshly ground black pepper. Sprisotto with parmesan and serveimmediately.
The work of rice researchers receivedmajor encouragement in 2007, with
aff at the International Rice Researchstitute (IRRI) and their colleaguesceiving widespread recognition andveral major awards.
“These awards and the recognition
at comes with them are clearnfirmation of the world-class ricesearch being conducted today insia and elsewhere,” IRRI’s Director
eneral Robert S. Zeigler said. “Moreople rely on rice for their sustenancean any other type of food. Millions,not billions, of these people live in
oor communities throughout the
veloping world. Research that helpsce farmers boost their production andcome, or helps reduce prices to make
ce more affordable, has the capacity pull vast numbers of people out of
verty and, therefore, does nothingort of offering them better lives.”
Outgoing IRRI Board of Trusteeshair Keijiro Otsuka accepted the
e Asia Pacic Culture Prize on behalf IRRI at a 12 October ceremony
uring the Asia Pacic Forum of thewaji Conference in Kobe, Japan. This
estigious award was established
2001 to recognize individuals andganizations pursuing cultural andcial activities within the Asia Pacicgion that have made outstandingntributions to the promotion of
ternational exchange and/or regionalvelopment. According to the Prizeganizers, IRRI has “made many greatntributions to reduce poverty and
lve environmental problems, and,rough your efforts, we expect that ine future you will further lead the way
to a multicultural society in the AsiaPacic region.”
Further validating the Institute’senvironmental credentials, IRRIentomologistK.L. Heongreceived the
Academy of Sciences for the Developing World (TWAS) Prize for Agriculture,
recognizing his pioneering work inecology and integrating biological andsocial sciences to promote integratedpest management, which has helped
millions of rice farmers reduce theirpesticide use. Dr. Heongrecei ved the p r i ze,
which included a plaqueand US$10,000, at the
18th TWAS GeneralMeeting held in Trieste,Italy, 13-14 November2007.

Tantawi A. Badawi, president of the Agricultural Research Center, Cairo,Egypt. They each received 500,000Japanese yen (US$4,630).
IRRI scientists also received several
awards at the 2007 Annual GeneralMeeting (AGM) of the Institute’s parentorganization, the Consultative Group
on International Agricultural Research(CGIAR). At the early December
meeting in Beijing, China, Dr. Brar was honored with the OutstandingSci enti s t Award, whi ch honorsoriginal work by a senior scientist
whose contributions have actual or
potential regional or internationalsignificance that furthers CGIAR goals. Dr. Heong picked up the COM+
Award for Communicating Science
for People and the Planet, honoringthe Environmental Soap Opera forRural Vietnam, an entertainment-education initiative led by Dr. Heongto help farmers improve their crop
management systems. A team of scientists led by IRRI
plant breeder David Mackill, in
collaboration with colleagues from theUniversity of California (Riverside and
Davis), won the Outstanding Scientic Article Award, also presented at the AGM. The winning paper, “ Sub1A isan ethylene response factor-like gene
that confers submergence tolerance torice,” appeared in the10 August 2006 issueof the journal Nature.
Authors K. Xu, X. Xia,
T. Fukao, P. Canlas, R.Maghirang-Rod-riguez, S. Heuer, A. Ismail, J. Bailey-Serres, P.C. Ronald,
an d Dr. Mackill described their dis-covery of a gene( Sub1A) that confers
submergence tole-rance to rice, and theconsequent breed-ing of this gene into apopular commercial
variety. The resultant variety isidentical to the popular cultivar butis able to withstand up to 17 days of severe ooding. Since the paper was
published, the IRRI team has bred Sub1A into several other popular varieties, which have undergonesuccessful on-farm trials and arepoised to make a big impact on ood-
prone farms in countries such asBangladesh and India. See Seeing isbelieving on page 6.

phone, and called George Harrar[then RF’s director for agricultureand later RF pre sident, 1961-72].He left the door open so I couldhear. He said, “George, I’ve got a
kid here. He set some sort of anacademic record here at Purdueand he wants to work for you and
what are you going to do about it?”
So, I had two phone conversa-tions with George Harrar. Duringthose conversations, he saidsomething I never forgot, “Would
you want to live in the Philippines?”
I said, “Of course!” That night, I hadto look in my atlas to see exactly
where in the Pacic the Philippines were. He said, “Well, we’re going
to do something there. It’s going totake 3 or 4 years to get organized.Meanwhile, we’ll have to ndsomething for you to do [ultimately,
brief stints in Mex ico and Colombia].”
I have a profound belief inpredestination, fate, and luck. Had I
been 5 minutes earlier or later that
morning at Purdue in the dean’sofce, I would not have crossed paths
with Dean Young, there would have been no phone conversations withHarrar, and I would have had a careeras a forage pathologist in the U.S.
George Harrar—hewas magnifcent!So, I got a job with the RockefellerFoundation in 1957. Terric! What’sthe signicance of this? Bob [IRRI’s
rst director general, Robert F.]Chandler’s book [ An Adventurein Applied Science] cites the year1958—about a year and a half a fter my
telephone calls with Harrar—as thetime when the Rockefeller a nd FordFoundations rst connected to thrashout the concept of IRRI. Harrar had“IRRI” on his mind when he talked to
me much earlier on the phone aboutrice and t he Philippines. You don’t seethat in Chandler’s book. The drivingforce behind IRRI was George Harrar.
He was magnicent, a giant! Getting germplasmin the early days
When I nally got to IRRI in October
1961—as a breeder, not a patholog ist—the rst challenge was to assemblea comprehensive world collection of
rice varieties. For germplasm, IRRIhad only some 300 odd varieties. Ispent a lot of time wandering back and forth in the mud trying to look
at these plants. I wrote a letter, co-signed by T.T. Chang [IRRI geneticist,1961-91], requesting any germplasmin small seed samples, and sent it torice workers or experiment stations
in some 60 countries. These werethe days when it was pretty easy tomove germplasm from one country toanother. The response was wonderful.
Within months, boxes and boxesof seed packages were coming in.I guess within 2 or 3 years we hadseveral thousand accessions.
Increasing rice yields Another challenge was more com-plicated. Chandler kept preaching:
increase yield! Okay, that’s easy tosay, but how do you do it? I spent a lot
of time talking with Akira Tanaka,head of IRRI’s Plant Physiology Department [1962-66]. We tried todevelop a mental image in our minds
of what the leaves, stems, culms, andgeneral architecture would look likeon an ideal rice plant that would yieldmore. We determined that, if we weregoing to make any progress, we had to
dramatically change the plant type.The rst seminar I gave at IRRI
was on what an ideal plant type hadto look like if we were going to gethigher yield. I wrote that up and
sent it to Crop Science [Plant typeas a rice breeding objective, 4:13-15,1964]. There were no data, it was
just philosophy. For some reason,
Crop Science published it. Yearslater, I reread that paper, long afterIR8 came out [in late 1966]. And it
just seems to me that IR8 looks very much like what we were theorizing.
An epiphany Well, the rest is history and just sheerluck. And it goes back to that rst set
of 38 crosses [that ultimately led toIR8] we made in late 1962. About half of them involved the three famousTaiwan short-statured varieties [Dee-geo-woo-gen, Taichung Native 1, and
I-geo-tze]. They looked terrible underPhilippine conditions. They wereriddled with bacterial leaf blight.
They were shaded by tall things. They were sterile and miserable, but short!
We grew out the F 1s [rstgeneration]—38 combinations,
which is ridiculous by today’sstandards. Thirty-eight crosses ina year—absurd! But that’s what wehad. So, we grew out the F 1s; they
were terrible. They were worse
than the parents themselves. They were gigantic—6–7 feet tall. Weharvested the seed from each of thesingle crosses—38 populations. And
for not having anything else, wehad a large F2 [second generation]population—4,000–6,000plants from each single cross.
Maybe a month after trans-
planting, one day we looked outthere. The plants from the rst cross
were tall—terrible. It was a jungle.
It was bad. Then, we came onto theplants from one of the crosses that
involved one of the three Taiwanshort-statured varieties. We lookeddown the rows. Something hadhappened! It was an epiphany! I never
had an experience like that in my life—before or since. There were tallplants and there were short plants,
but there were no intermediateplants! The short ones were erect,
darker green, and had sturdy stemsand a high number of tillers. Wecounted the tall plants and short
plants. Essentially, the ratio short was 3 to 1—obviously agene recessive for shortness!sound something like arroga

These maps show how rice
production is concentrated inSouth, Southeast, and East Asia.Maize production is particularly high in North America and China,
but it is relatively evenly spreadacross countries. Wheat is a crop
of temperate and subtropicalclimates, including being a wintercrop in northern India, but it ismostly absent in tropical countries.
Root and tuber crops are relatively important in sub-Saharan Africa(particularly cassava), China (sweetpotato), and Central Europe (potato).
The amounts produced in a
country in part reect the number of people living there. To some extent,that explains why China, the world’smost populous country, is a large
producer of all crops mapped.The maps of Figure 2 show
cartograms of daily per personconsumption of these crops.

maps account for the number of people in a country, but they are also
inuenced by international tradeand the degree to which the cropis used for (direct) consumption.
Rice consumption per person in West and East Africa is higher than
you would expect from the productioncartograms. This is in part becauseof rice imports. Particularly strikingis the importance of maize in Africa,

ticle. This undoubtedly leads tovery important question: Whatservations does Dr. Conklin make
om the photographs and, apart
om being a magazine editor’seam, what is their signicance,
culturally and scientically?Dr. Conklin, now professor
emeritus at Yale University,Connecticut, began his research
on the Ifugao people in 1961 andhas since devoted half a lifetimeto studying these architects of thefamous Banaue rice terraces. Inaddition to the Ifugao’s well-known
magnicent skills in agriculturalterracing, he has observed andexamined their intricate ritualand legal systems; their distinctive
patterns of social organization, sex,and warfare; their rich oral literature;and their artistic achievementsin wood carving and basketry.For more about the Ifugao, see
Contours of change, on pages 8-13 of Rice Today Vol. 3, No. 1).
“I took my rst aerial photo-
graphs of the Ifugao area from asmall plane in the summer of 1961,”
says Dr. Conklin. “I also arrangedfor concentrated photographicefforts in 1962, 1963, 1968, and 1969.
Additionally, I had vertical aerial
pictures taken, which facilitatedthe photogrammetric plotting and

mapping of a signicant part of the region. During those years, I
also took many photos of Ifugaorice agriculture at ground level (seepage 22).” Many of these photos
and resulting maps appear in his Ethnographic atlas of Ifugao (see
box on the next page) published in1980, some of which are reproducedin this article with permission from
Yale University Press for comparison
with those taken during the March2006 Conklin-Javellana foray.
“Unfortunately,” says Dr. Conklin,“during the 1960s, I never had thechance to survey the whole areafrom the air at the same time. But,thanks to the unusual break in the
often dense cloud cover, Biggs and I were able to do this over most of the140+ traditional Ifugao agriculturaldistricts (within 9 of the province’s 11municipalities; see map on page 14)
spread across a vast area of ruggedterrain.” Up until then, he had walkedthrough some of the valleys only onceor knew of them only from reputation.

According to Dr. Conklin, hisry preliminary inspection of the
hotos has yielded some fantasticd perhaps surprising ndings.
Of course, the greatest changesross Ifugao have been in the vast
mprovement and expansion of
roadway networks and populationgrowth, especially along theseroutes,” he says. “The town centersof Banaue (photo at top of page 19)
and Lagawe are now tremendouslittle cities instead of small crossroadhamlets.” However, when ying overmost of the districts, they found thatthe agricultural centers—the places
where the largest pond elds arelocated—have not been affected by theurban sprawl or the roadway system.
The photos show that no valleys
where agricultural activities wereunder way in the early 1960s have
been abandoned since then. Dr.Conklin pointed out that IfugaoProvince is blessed with abundant
rainfall and irrigated elds are keptinundated during all seasons.
“Cement has been the greatest
additional ‘concrete’ input,” he says with a smile. “It did not exist before—
at all. The cement does not go intothe pond elds or into agriculturallandscape. It stays along the roads,
which are usually above the terraces
and the agricultural land below.”
One thing that truly surprisedand impressed Dr. Conklin is theamount of forest land in Ifugaotoday. “Looking at any early picture
of an Ifugao agricultural district (asa whole) will show considerably lessforest cover than was revealed by ourrecent survey,” he says. “In terms of luxuriousness, density, and height,
the forest landscape is remarkable,a situation not at all the case in mostof the rest of the Philippines.”
Why is this? Dr. Conklin surmises
that, as in many other parts of thePhilippines, Ifugao overseas workersare sending back remittances, whichhave allowed many Ifugao remainingat home to buy imported food and be
able to eat rice more than once a day.“Certainly, the amount of rice
being produced on the terraces has
also increased tremendously,” he says,“but unquestionably the Ifugao diet is
now less dependent on sweet potatothan before. Previously, most Ifugaodidn’t eat rice two or three times aday throughout the year. They often
depended on sweet potato tubers

cultivated in temporary slopelandelds that did not have access tosufcient water for rice eld terracing.
The area devoted to these shiftingcultivation plots has very greatly diminished and has grown back assecond growth forest and woodlots.”
Dr. Conklin speculates why there
are so many Ifugao overseas workers who have directly made it possiblefor local forests in the province toourish by putting less pressure on
the land. “The Ifugao were among therst Cordilleran pioneers to venturefar from home, initially in-country and then around the world,” he says.
One unique cultural quirk
contributing to so much out-migration from the province is theIfugao custom of primogeniture,that is, inherited elds are not split
up. Explains Dr. Conklin: “If thereare seven children in a family (andeven today, there often are), only the oldest will get the ‘lion’s share’of the landholdings. The rest of the
siblings have to seek their livelihoodselsewhere.” Also, there are noabsentee landlords. Very little land
is in the hands of others outside of Ifugao. Land tenure and land usage inIfugao have traditionally been tightly
managed and integrated culturally.Some other ecological obser-
vations that can be made fromcomparing photos from the 1960s
with those taken in 2006 show
that many partially terraced areashave expanded a little. However,signicant new terraces can bedetected in only about three or four
districts, such as shown in Hu’yu(see photo at left). “They are very important for these people who havenot had much land before,” says Dr.Conklin, “but I don’t think these
new terraces are very economic.” At the spry age of 82, Dr. Conklin
is working on yet another book tocomplement his ethnographic atlas.
Featuring Ifugao rice specically, it will show the staple from a traditionalIfugao view. “I am tapping into a large
body of information that is shared by the people living in the agricultural
districts and doing the agricultural work in the pond elds all year long,”he says. “What do they know about
rice? How do they feel it, tast with it, use it, classify it, samand use all of its by-products

the 26th session of the Councilof Ministers of the Africa RiceCenter (WARDA), held in Abuja,
Nigeria, 27-28 September 2007,signaled a historic change for rice
research in sub-Saharan Africa.The expansion of the geographic
mandate of WARDA, which is
primarily based in West Africa, wasformally approved and four East
and Central African countries wereadmitted as WARDA members.
The new member states areUganda—the rst East African
country to be admitted to WARDA—the Central African Republic, theDemocratic Republic of Congo,and the Republic of Congo. Theseadditions take the number of WARDA
member states from 17 to 21.“This is the rst time since
1987 that new members have joined WARDA,” stated WARDA DirectorGeneral Papa Abdoulaye Seck. “But
what is more important is thatthe new member states are fromEast and Central Africa—regionsthat, unlike West Africa, were not
traditionally knownfor rice cultivation.”
“With the succe ss of WARDA’stechnologies, particularly theNew Rice for Africa (NERICA
®),
Central and East African countriesare seeing for themselves the
benets of investing in rice
research,” Dr. Seck said.In his opening address, His
Excellency Umaru Musa Yar’Adua,president of the Federal Republicof Nigeria (represented by the vice-president, Dr. Jonathan Goodluck,
who delivered the message) men-tioned that, aside from NERICA,another major contribution from
WARDA to Nigeria was in thearea of rice policy research.
The Council of Ministersthanked Dr. Seck for his strongadvocacy for rice research anddevelopment, which has ledto tangible improvements in
contributions from member states—including Nigeria, which hasfullled its nancial obligationsto WARDA to date.
“The contribution receivedfrom member states in 2007 isequivalent to that of the last 10
years,” the Council afrmed.The Council strongly backed
a new pan-African Rice Initiativethat will be launched in 2008 by Benin President Yayi Boni with
WARDA, as part of advocacy efforts
to support Africa’s rice sector.Dr. Seck’s vision and strategy
for a more competitive, diversied,and sustainable Africa RiceCenter were fully endorsed by the

Ganakabari is a small village
with 87 households inJorhat District of the Indianstate of Assam. Every year,
e low-lying area is subject to deepoding due to monsoons that causee overow of the Brahmaputrad Bhogdai rivers. For centuries,
ce has been the major crop of
e area, the staple of the localpulation. During the kharif (wet)ason, farmers monocrop sali rice;eir next crop consists of seasonalgetables, oilseeds, and pulses.
ost farmers in the village arether marginal, having less than 1ctare of farmland, or small, with
farm size of 1–2 hectares. Most
rmers have a primary education.The average yield of sali rice
only about 2 tons per hectare.he combination of small farmsd poor yields is a formula for
verty in this area. Compoundingis, the Brahmaputra and Bhogdaiten cause ood damage to the sali ce, contributing further to food
security and poverty for the localrmers. To improve livelihoods inch areas, farmers wanted to grow
ce during the dry (boro) season.Monsoons bring too much
ater but the dry season bringso little. Therefore, irrigation is aust for boro rice. To encourage
boro rice cropping, the Assamstate government started providingsubsidies for low-lift pumps in the
year 2000. Five farms began boro
rice cropping for the rst time duringthe 2002-03 season, irrigating about2.5 hectares of land using the pumpsto lift water from the Bhogdai River.
Although they had water for
irrigation, the farmers lacked anappropriate variety of boro rice. Intheir rst boro season, they grew an unknown variety, the so-calledNo. 9, and two sali varieties— Luit
and Lachit . No. 9 yielded about 5tons per hectare; the sali varieties
yielded about half that.From 2003 to 2004, Assam
Most farmers have not aban-doned sali rice; rather, they haveadopted a boro–sali system. Boro rice is currently grown on about 30%
of rice lands in Ganakabari. About70% of the land is now under thesali–boro system; the other 30% isplanted to boro only. Among the threeintroduced boro varieties, Kanaklata
has become the most popular.Rajib Neog is a young farmer
from Ganakabari village. With asecondary education, he has more
schooling than many farmers.His brother, a school teacher, hassettled with his family in the nearby suburban town of Dergaon. Histhree sisters are all married and
have settled in other villages withtheir families. Rajib, the youngestsibling, remained at the family
house in Ganakabari village tolook after his elderly parents and
their 2-hectare farm. Cultivatingmostly rice and seasonal vegetables,his family’s life was difcult.
A receptive and technology-savvy
farmer, Rajib saw the potential of boro cropping. In 2002-03, he wasone of ve farmers who cultivatedboro rice for the rst time in the
village. In 2003-04, he adopted the
Kanaklata and Joymati varieties,and BINM, on 1.2 hectares. Later,he increased the coverage to 1.5hectares—75% of his land.
In the 2004-05 season, Rajib
had stunning success with his rstattempt at growing Kanaklata. Hereaped 6.25 tons per hectare, while
yields of the sali varieties averaged
2.3 tons per hectare. Rajib’s yield was the highest in his village. In the2005-06 season, Rajib also harvestedan excellent crop that yielded 6.3tons per hectare. In 2004-05, his
total harvest was 8.5 tons; in 2005-06, his total harvest was 9.95 tons.
Rajib expected another bumpercrop in the 2006-07 boro season.
In addition to the higher yields of Kanaklata, Rajib grows the variety for its ner grain quality, goodeating quality, and high marketprice. Currently, he is growing
mostly Kanaklata and No. 9.By adopting the new technology
package, Rajib has been able to grow
more rice thanhe needs andhe has becomea relatively
wealthy farmer.Occasionally, his
brother collectsrice from Rajibfor his family’s
consumption.Higher yieldsalso mean thatRajib has become
a grower of Kanaklata seeds.He stores most of his product until
just before the next planting seasonand then sells it at a good price.
In 2005, Rajib earned about24,000 rupees (US$600) by selling4 tons of rice seeds, and in 2006
he earned 36,000 rupees ($900) by selling 6 tons. In addition
to income from rice farming,Rajib earns supplementary income by growing vegetablesand raising goats and ducks.
People who know Rajib cansee physical proof of his improvedlivelihood. In 2005, in preparation forstarting his own family, Rajib usedthe additional income to construct an
improved mud-walled tin-roof house.In July 2006, he married Pranita(Munu), who has become his constantcompanion. Rajib also bought asingle-burner gas stove for cooking,
which saves his family the time andlabor of nding rewood for cooking.
In Ganakabari and beyond,people quickly gure out who the
prosperous farmers are. Successfulboro cropping with record high
yields has brought a degree of fameto Rajib. Many seek his counsel:neighbors in his farming community,
scientists at development agenciesand nongovernmental organizations,and agricultural extensionspecialists at the state government’s
Department of Agriculture.In April 2006, Rajib achieved
formal recognition as a successfulfarmer. Participating in a trainingcourse on seed selection and storage,
presented at AAU by experts from theInternational Rice Research Instituteand Bangladesh, Rajib received
Agricultural University (AAU) atJorhat initiated efforts to intensify boro cropping at Ganakabari, incooperation with the International
Fund for Agricultural Development(IFAD)-funded project TAG 634:
Accelerating technology adoptionto improve rural livelihoods in therainfed eastern Gangetic Plains. The
AAU research team provided farmers with modern boro varieties developed by AAU— Kanaklata, Joymati,and Jyotiprasad —and offeredinformation and technical support.
In the 2003-04 season, 24farmers cropped boro rice in a27.5-hectare area. The AAU teampromoted biofertilizer-based
integrated nutrient management(BINM), which reduces the use of inorganic fertilizers and thus lowersproduction costs and water pollution.
In the 2004-05 season, 33
farmers grew boro rice on 39 hectaresand, in the 2005-06 season, 25farmers cropped boro rice on 20hectares. The decrease in 2005-
06 was caused by severe drought, which raised the cost of fuel and,consequently, irrigation. Mostfarmers who grew these modern
varieties harvested more than 5

Bright oranges, rich
yellows, piles of husks in
wheat-colored hues—allmaize, no rice.
This was the scene in late August2007 throughout towns on the
Philippine island of Luzon in theCentral Region, Cagayan Valley, andthe Ilocos Region (see brown-shadedarea of map). Drought hit these areas
in July, forcing most rice farmers toplant maize, vegetables, and otherdry-season crops instead of rice.
Venturing north from its LosBaños headquarters, Rice Today
expected to see parched land studded with dry rice plants, but there werenone. Our rst reaction was relief
for the farmers mixed with fearsthat our attempt to document the
effects of drought would be futile.Fortunately—or unfortunately—afterseveral interviews with farmers andfarm workers, we discovered that
the absence of dry rice elds wasnot because the reports of droughthad been exaggerated, but becausemany farmers had simply ceasedtheir planting operations altogether
due to the absence of rain.“Most of the farmers here did
not plant rice anymore when we
knew there was a drought,” explainsMarlon Ortilla, 34, a rice farmer in
Sinait, Ilocos Sur. “I planted riceseeds on 24 June but was able totransplant the seedlings only on 25
August due to drought. The 2-month
delay caused yellowing of the riceseedlings, which is no good.”
Like many other rice farmersin the area, Marlon Cabato, 42,from Amulog, Cagayan, planted
maize instead of rice. “We shouldhave started planting rice inJune,” he laments, “but because

cause of the drought,” relatesolando Diego, 52, of Allacapan,
agayan. “Our planting waslayed for 4 months, but I planted
some maize. It hardly rains
here. This October, I’m hopingfor a good harvest, because my
last harvest was in 2006!” According to the Philippine
Department of Agriculture (DA), when the dry spell struck, farmers
had already planted rice on 1.071million hectares of land, with
maize planted on another 288,311
hectares. The DA noted that, of thetotal area planted, 85,741 hectaresof land planted to rice and 128,543hectares of land planted to maize
were affected by the dry spell.
In early August, the DA startedgiving aid to small farmers reelingfrom the dry spell, in efforts to boost
yields and help put agriculturalgrowth on track despite the adverse
climate. Aid provided several meansof assistance including cloud-seeding, shallow tube wells, seeds,and water-impounding projects.
But, for most farmers, help cametoo late to save their crops. “Because of the drought, planting
was delayed for 2 months, and, when we were nally able to plant, atyphoon hit us,” says Angel Parayo,
68, who lives in Candaba, Pampanga.“All my seedlings were submergedin water for 5 days; the seedlingsrecovered but the palay [rice] becamesoft, which could cause losses.”
The weather has meant that,
for many rice farmers, this yearhas been disappointing in termsof harvest and income. This, inturn, had a negative impact on
business in general in this region.“Business is suffering,” says
a gas station owner in Tumawini,Isabela. “All the businesses hereare dependent on farmers’ produce.

his highly effective pest controlmuch greater than that of most
mperate agroecosystems, andce agroecosytems are arguably me of the most diverse in the
orld. Both the diversity and
mplexity of species interactionsntribute to the robustness of tural pest control—a free serviceovided by the ecosystem.
Why is the biological control
irrigated rice so unique amongroecosystems? Early in theopping season, ooding of the eldmulates the activity of aquatic
sects, such as midge larvae, whiched on decaying plant material.hese species are harmless to theop, but have a benecial role forst control. When the aquatic insects
merge out of the water to y away,ey are consumed by hungry spidersd predatory insects. The predator
populations mostly feed on the
emerging aquatic insects early in theseason, and then switch to feed on theterrestrial insect pests as the canopy closes and aquatic insect populationsfall. Thus, the predators benet from
an early ush of food that helps to build up their populations beforeinsect pests become abundant.
Many modern rice productionpractices actually favor pest
outbreaks. For instance, populationsof sucking insect pests such as the
brown planthopper (BPH), greenleafhopper, and aphids are actually
limited by the amount of availableprotein. When too much nitrogenousfertilizer is added, plants havean excess of amino acids in theirsap, which favors the buildup of
sucking pest populations. Leaffolder
moth damage also increases whenfertilizer is overused. Therefore,excess fertilizer makes the entiresystem more vulnerable to pests.
If biological control is so
effective, what causes insect pestoutbreaks? The two most importantinsect pests of rice throughout Asiaare the yellow stem borer and theBPH. Found every season throughout
the rice-growing regions of Asia, the yellow stem borer’s ubiquity has givenit a reputation as a major pest—yetit causes only 2–5% yield loss. Stem
borer damage during the vegetativestage of rice plant growth does notcause yield loss because the plantcan compensate by growing more
vigorously. Only stem borer moth
damage during the reproductive stageresults in yield loss, and research hasdocumented that there is a strongtendency to overestimate such loss
because the white, unlled panicleslook particularly bad to farmers.In truth, the yellow stem borer isnot really a signicant pest that
warrants serious interventions.
The BPH, however, wasresponsible for huge and devastatingoutbreaks throughout Asia in
the 1970s, and is considered thepreeminent pest of the GreenRevolution. Some of the key factorsthat facilitated BPH outbreaks
during the 1970s were year-roundcropping of rice, increased use of nitrogenous fertilizer, and the useof insecticides known as syntheticpyrethroids. These pesticides kill
off the natural enemies (known aspredators and parasitoids) of BPH,allowing subsequent cohorts of BPHa predator-free period to develop.
Because their populations developmore quickly than the predators, BPHpopulations can result in an outbreak,causing devastating losses. Repeatedpesticide overuse over large areas can
reduce the ability of natural enemiesto recolonize and establish natural
biological control (see The pesticide
paradox on pages 32-33). In areasthroughout Asia where pesticide
subsidies have been terminated, BPHoutbreaks have largely stopped. Butin countries where there has beenan increase in pesticide production
and pesticides are cheap, there have been sizable BPH outbreaks. In 2005,
about 2.7 million tons of rice werelost in China alone. In 2006, Vietnam
suffered enough rice crop losses dueto BPH and secondary viral outbreaksto threaten the country’s rice exports.
Are there ways to boost and

William Settle and colleaguesreported that adding manure to
rice elds boosts natural control. At the International Rice ResearchInstitute, my team is studying therelationship between manure inputsand rice variety on natural biological
control. We have found that 2 tonsof composted manure added at the
beginning of the season signicantly lowers stem borer damage during
the reproductive phase—the period when pest damage is the mostdifcult to manage. It also appearsthat some plant varieties show slightly higher levels of damage than
others. Currently, we are evaluatingmanure as a pest-management tool by determining whether more manurefurther increases pest control. This
will allow us to make simple pest-management recommendations for
boosting natural control in farmers’elds. So far, we are encouraged
by these positive pest contromeasures, which appear to b

If pesticides are supposed tocontrol pests, why does an
enormous reduction in useactually lower their numbers?Tests performed on the
search farm at the Philippines-
sed International Rice Researchstitute (IRRI) have shown that,pesticides are used less and less,en nature itself, in the forms of edators and parasitoids, will join
e ght on the farmers’ side.The research, performed by a
am led by IRRI entomologist K.L.eong,
1describes how, when IRRI
rm operations were centralized1993, a new scheme for sprayingsticides was introduced. Insteadroutine spraying once a week,sticides would be sprayed only
when pest densities in a eld reacheda certain level. Dr. Heong writesthat “in most seasons, insect pestpopulations did not reach thresholdlevels and thus no insecticides
were used.” After 14 years of theprogram, pesticide use on the farmhas decreased by a staggering87.5%. Insecticides, which are the
main type of pesticides used on thefarm, have fallen in use by 95.8%.
The study focuses on arthropods:invertebrates with a tough externalprotective layer (called a chitinous
exoskeleton) and segmented bodies,and which make up more than80% of all living animal species.For the paper, the arthropods were
separated into four functional groups:herbivores, predators, detritivores,and parasitoids. Herbivores attack rice plants. Predators and parasitoidsattack herbivores and detritivores.
Detritivores eat detritus in the eld. Arthropods on the farm were
surveyed in 1989, well before theintroduction of the spraying schemein 1993, and in 2005, well after it.
Comparing those two surveys revealssome telling gures. In 1989, 46.2%of the arthropod population on thefarm was herbivores. In 2005, when
arthropods were next counted, only 11.2% was herbivores. The number of predators had risen from 40% in 1989to 58% in 2005. Detritivores in 2005formed 26.1% of the total arthropod
density, up from 8.1% in 1989.Parasitoids experienced a smallerchange: 5.6% in 1989 to 4.3% in 2005.
The reason for these swings
is the unintended effects of pesticides. Pesticides can affect allcreatures. Predators, parasitoids,and detritivores can be killedalong with herbivores. In fact,
because of their superior mobility,predators are more likely to comeinto contact with the poison and
thus are often more exposed tothe toxins than herbivores. And, if predators are killed off, they can’thelp suppress herbivore numbers.
As well as killing nontargetarthropods, heavy pesticide use canhelp “secondary pests”—which arefavored when predator numbersare lowered—to rise to power. In a
balanced ecosystem, the numbers of secondary pests stay relatively low.But, if large numbers of predatorshave been killed, secondary
pests face less competition fromprimary pests and can thrive.
Reducing pesticide use lets both the predator and parasitoidpopulations recover, thereby keeping
secondary pest populations low. Also, because fewer predators are beingkilled through pesticides, their food
sources—pests and detritivores—remain abundant and their numbers
can swell. This is natural pest control.Dr. Heong’s team also compared
the arthropod diversity before andafter the introduction of the low-
pesticide regime. Sure enough, the2005 survey showed that the diversity of all four types of arthropods hasincreased signicantly. Accordingto the paper, “there were twice as
many species of herbivores, about48 more species of predators andparasitoids, and greater than 5 timesmore species of detrit ivores.”
More species of herbivores may
not seem good for rice, but such anacross-the-board increase in diversity is a sign of a healthy ecosystem,especially as many of the species
that survive under low-pesticideconditions are unimportant pests.For an ecosystem to thrive, theorganisms in it must be diverse andadaptable. In particular, a diverse
range of predators helps preventpest invasions or outbreaks, whichcan often be caused by abnormalclimatic conditions. Thus, a
balanced ecosystem with adequatefunctional biodiversity will alsohave reduced vulnerability toadverse effects of climate change.
For poor farmers, the key part in
the question of pesticide use remainsthe debate of “y ield versus prot.”
With intelligent and focused use of
pesticides, yield can be increased.However, Dr. Heong suggests thatmany poor farmers do not benetnancially from using pesticides. For
example, a study in the Philippinesshowed that farmers overestimatedtheir potential loss of prot due tostem borer infestation by ten times(see The unsung heroes of the rice
feld on pages 30-31). The money they were spending on pesticides
was more than double their actualloss. On top of that, the low-quality
sprayers that poor farmers useoften result in less than 10% of the pesticide reaching its target.
For poor farmers, then, the costof spraying pesticides can outweigh
the benet. To lower pest numbers,improve diversity, and increaseprots, many farmers should steadily
cut down on the pesticide they use.The challenge is to persuade them to
reduce their pesticide use in the rstplace. Poor farmers, who have toonarrow a prot margin to experiment
with production techniques to
improve yield, tend to be loss-averse—if the crop fails, they go hungry.
This is where advertising andnational governments can play a
key role. In Vietnam, for instthe national government andIRRI cooperated on a large-sinformation campaign called
Giam Ba Tang (Three ReducThree Gains). One of thosereductions was in pesticide uThe campaign has contributeto decreasing pesticide use in

Rice Today January-March 2008 Rice Today January-March 2008
When I learned that
I had been selectedto travel to thePhilippines andBangladesh to work
the International Rice Research
stitute (IRRI) as a World Foodize Foundation intern, I was bothstatic and apprehensive. My closestcounter with rice farming haden the steaming bowl of rice that
me with my orange chicken ate local Chinese restaurant in my metown of Iowa City. I had neveren to Asia or seen a rice eld.
The Foundation, like the Worldood Prize, was founded by Normanorlaug, who received the 1970obel Peace Prize for his work to
boost agricultural production in
the 1950s and 1960s, thus spurringthe Green Revolution and helpingto avert mass starvation at a timeof dramatic population growthand stagnating crop yields.
Based in IRRI’s Social SciencesDivision under the supervision of Mahabub Hossain (then divisionhead, now executive director of theBangladesh Rural Advancement
Committee), I spent the rst few weeks of my internship reading booksand articles relating to the SeedHealth Improvement Project (SHIP).
SHIP was conducted inBangladesh in 1999–2004 underthe Poverty Elimination ThroughRice Research Assistance project
funded by the
UK Departmentfor InternationalDevelopment.Coordinated by IRRI
plant pathologist TomMew, SHIP involvedcollaboration betweenthe Bangladesh RiceResearch Institute,
IRRI, and CABIBioscience (UK).Several local and
international nongovernmental
organizations also played signi-cant roles.
With around 150 million peopleand one of the highest populationdensities in the world, Bangladesh
must overcome a lot of obstacles tofeed its people. The population of Bangladesh increases by about 2million people each year, meaningrice production must increase
around 300,000 tons annually if everybody is to be fed. SHIP taughtfarmers improved seed selectionand storage practices designed to
increase rice yield and prevent losses.More than 90% of the seeds
planted each year in Bangladeshare retained from the farmers’ ownharvest, and most are of poor quality.
Many farmers simply save some of their harvest, dry it on the ground,and store it in open containers or
bags. This means that the seed they
plant each year is often infested with insects and contaminated with soil and other plant matter.Planting good-quality seed canincrease yield up to 12%; SHIP
technologies and training sought tohelp farmers achieve this increase.
SHIP introduced several
simple methods for improving
seed health, including roguing(removing undesirable plants fromthe eld) before harvest, selectinggood panicles for seed, dryingseed, and storing seed in airtight
containers with additives suchas naphthalene and neem leavesto prevent insect infestation.
One unique aspect of SHIP was its participatory approach to
training women from resource-poorhouseholds. Farmers’ knowledgeand input were used at each step,and this had a profound impact
on the success of the project.Having equipped myself with as
much knowledge about seed healthas I could gather, I nervously boardedthe plane that would take me to
Dhaka, the capital of Bangladesh.I had read that Bangladeshis neversmile, that they eat only withtheir right hand, and that women
were hardly ever seen in public. Adding to my disquiet, massive
oods had swept the Chittagongregion of Bangladesh, causingmudslides that killed more than
90 people, only days before. Allof this raced through my mind asI sat on the tarmac of the Manila
airport. “What have I gotten myself
into?” I wondered nervously asthe Philippines became a speck in the ocean behind me.
The answer, it turned out, wasthat I had gotten myself into the
experience of a lifetime. While it istrue that Bangladeshis eat only withtheir right hand, almost all of my preconceptions about the country
were completely vanquished. I spent
a lot of time with very bold women,and even more time listening to theBangla language oat around my headas the room broke out in laughter.
Although we had very differentcultural practices and understand-ings, my Bangladeshi friends andco-workers graciously overlookedmy clumsiness in their culture.
From my supervisors in the IRRIofce to the vendors on the street,everyone I met tried to make meas comfortable as possible.
After the incredible hospitality, what struck me most was thepoverty. From the beggars on thestreets of Dhaka to the farmerstoiling to eke a living out of
their land, extreme poverty wasevident throughout the country.

RICE FACTS
Of the world’s 1.1 billion poorpeople, almost 700 millionpeople with income of lessthan a dollar a day reside in
ce-growing countries of Asia. Ricea staple food in Asia and accountsr more than 40% of the caloriensumption of most Asians. Poorople spend a large proportion of
eir income for buying rice. The levelrice production and prices is thusimportant factor in determining
e progress that can be made inducing poverty in Asia. Keeping
e price of rice low and affordablethe poor is crucial to poverty duction. Given this, the currentstained upward trend in rice
ice is a major cause for concern.The Green Revolution in Asia
d to a rapid rise in rice yield andoduction. This contributed toverty reduction directly through
creased income of rice farmers anddirectly through a lower price of ce, which beneted poor consumersboth rural and urban areas (FigureThis long-term decline in rice
ice, however, seems to have comean end in 2001, with the rice price
king a sustained upward turn overe past six years. The rice price
ntinued to increase during 2007d this upward trend seems unlikely reverse anytime soon (Figure. Although a part of the increaseprice can be explained by the
ntinued depreciation of the U.S.llar, there are other fundamental
nderlying causes of this rise in price. A rise in the price of rice

e stock. In fact, rice stocks areing rapidly depleted, with therrent stock being the lowest since

production, which will ultimately contribute to a price reduction.This traditional solution, however,is morally and economically
unacceptable in the case of rice because any rise in price will affectthe poor disproportionately and
will lead to an increase in hungerand poverty. Indonesia provides a
case in point: the number of poorpeople increased by several millionas a result of a steep rise in the priceof rice that occurred in the wake of
the Asian nancial crisis of 1997.There is no doubt that the economicand political turmoil Indonesia
went through was compounded by the dramatic jump in rice price.
Demand for rice in Asia isexpected to continue to rise in thefuture as its population expands.
Even after allowing for some decreasein per capita consumption in Asian
countries that have higher incomelevels, the projected demand for
Asia is an additional 38 million tonsof rough rice by 2015. Additional
demand is likely to arise from Africa, where rice is becoming anincreasingly important food crop.The worldwide increase in demand
by 2015 is estimated to be 50
million tons of rough rice per year.The best strategy for keeping
the price of rice low is to increase itsproduction at a higher rate than theincrease in demand. Rice production
can be increased by expanding thearea, by increasing the yield perunit area, or by a combination of the two. The opportunity for further
increasing the rice area in Asia isnow quite limited. Rice productionis facing increasing competition forland, labor, and water from othereconomic activities and the recent
growth in biofuel production islikely to exert additional pressure.China provides an example—ricearea decreased by almost 3 million
ha between 1997 and 2006 becauseof this economic pressure. Althoughthere may be some potential forexpansion of rice area in othercountries, the total rice area in Asia
will unlikely increase much beyondthe current estimate of 136 million ha.
Given this, the main source of
additional production will have to be yield growth. Unfortunately, thecurrent rate of yield growth is toolow to generate the required supply.In the major rice-growing countries
of Asia, yield growth during thepast 5–6 years has been almost nil(Figure 4). The problem is likely to becompounded by increased production
risks arising from global warming by adversely affecting rice yieldand by increasing the frequency of events such as drought and ood.
Productivity growth through
the development and disseminationof improved technologies is theonly long-term viable solution for
preventing rapid increases inprices. A second Green Revolto reverse the rising trend inprices and to keep prices lowneeded now as much as the
Green Revolution was needeearlier to avoid famine and mstarvation. The task is equallchallenging but not insurmo
provided a substantial boostgiven to agricultural research
which continues to remain hunderinvested. Increased resinvestments together with po
reforms that make rice markefcient will ultimately help rice prices low and reduce po

otherwise. A current low level of stock, however, compromises theability to have such a moderating
inuence in the future and increasesthe risk of a sharp rise in price.
There is a saying in economics
that “the solution to a high price isa high price.” High prices provideincentives to producers to increase

grain of truth

Balancing ertilizeruse and proft
Less ertilizer
use can mean
lower crop yield
and less proft
As fertilizer prices increase, research and extensionoften send farmers a message of “reduce fertilizeruse to save money.” But, crop yield is directly
related to the amount of nutrient taken up by theop. At some point, less fertilizer use means lower cropeld and less prot for farmers. How much fertilizer use isst right for high prot?
The answer can come from site-specific nutrient
anagement (SSNM). This approach to farming enablesrmers to optimize their use of fertilizer by matchinge amount and timing of each added
utrient (nitrogen, phosphorus, andtassium) with the needs of the crop
r each nutrient.Nitrogen (N) is typically the
utrient that most limits rice yieldsd hence the nutrient needed in largest
uantity from fertilizer. Much of the Na mature rice plant comes from theil. On a typical rice soil in the Asianopics, the yield of irrigated rice oftenaches about 4 tons per hectare w ithout
plication of N fertilizer, as long as cropanagement uses best practices and
ater is sufcient. But, markedly higherelds of irrigated rice are required toeet food needs and achieve higher
ot for farmers.How much N is needed from fertilizer to increase rice
eld from a baseline—in which the crop obtains its entirefrom soil—to a yield that provides the highest prot for a
rmer? Based on SSNM, about 40 kg N from fertiliz er muste added to increase grain yield by 1 ton per hectare in agh-yielding season (typically the dry season) and about to 60 kg N is needed to increase grain yield by 1 ton in a
w-yielding season (typically the wet season).
Assume, for example, that a farmer can typically hieve a rice grain yield of 5 tons per hectare in the lowerelding season during the year. Achieving this yield woulden require sufcient N from fertilizer to increase yield by
out 1 ton from the baseline of about 4 tons per hectare.his requires about 50 to 60 kg fertilizer N per hectare.
sume that the farmer can typically achieve a rice yield of ons per hectare in the higher-yielding season. Achievingis yield would require sufficient N from fertilizer to
crease yield by about 3 tons from the baseline of about 4ns per hectare. This corresponds to three times 40 kg orout 120 kg fertilizer N per hectare. Through the use of
such simple guidelines, extension workers and farmers canquickly evaluate current practices, thereby determining
whether more or less N fertilizer is required. The required
N fertilizer should be split into about three applicationsduring the growing season based on SSNM principles foroptimally “feeding” the needs of the crop for N at criticalgrowth stages.
The needs of rice for phosphorus (P) and potassium (K)
are directly related to grain yield.P in fertilizer is expressed on the basis of its oxide
form—P2O5. For each ton of grain yield,
a mature crop of modern high-yieldingrice typically contains the equivalent
of about 6 kg P2O5 within its biomass.Hence, a 6-tons-per-hectare cropcontains about 36 kg P2O5 at maturity.Two-thirds of this P is in the grain.
Therefore, with the harvest of grainand removal of some straw, about 5 kgP2O5 per hectare is removed from a riceeld for each ton of grain yield. Hence,for a 6-tons-per-hectare crop, about
30 kg P2O5 must be replaced using Pfertilizer.
As a general principle, irrigated rice with a history of P fertil izer use requiresabout 4 to 5 kg P2O5 per hectare from
fertilizer—depending on the amount of straw retained—for each ton of grain yield to maintain soilfertility and achieve high prot.
The need for K fertilizer depends upon the management
of rice straw—which contains most of the K in a rice crop.It also depends on K contained in irrigation water and theK-supplying capacity of the soil, which are typically notknown by farmers. SSNM provides farmers with a simpleeld plot technique for tailoring K fertilization to eld-
specic needs.The capacity of soil to supply nutrients and promote yield
can vary markedly among elds of rice farmers. The SSNMapproach helps farmers determine the needs for nutrients in
their specic elds based on simple observations.
