Present status of rice production in Asia and the Pacific
In 2001-2012, in Asia:oRice area increased 0.8 million ha per year (0.57% per year)oYield increased 45.4 kg/ha per year (1.08% per year)oProduction increased 9.8 million tons per year (1.66% per year)
Based on FAOSTAT
Area (million ha) of irrigated rice, rainfed lowland rice and upland rice and their percentage of total rice area
Challenges of rice production in Asia and the Pacific
oExisting prevalence of hunger and poverty: 600 million in poverty and 500 million in hunger and malnutrition. Among the poor, rice farmers are predominated. oPopulation continues increasing (from 4.3 million in 2013 to 4.9 million in 2030)oEnvironmental degradation occurred in most rice ecosystemsoGlobal climate change affects rice production (extremes events, raised sea water level, increased temperature, …), and rice cultivation contributes to increased global warming (methane and NO2 emissions, …)
Challenges of rice production in Asia and the Pacific(cont.)
oFour “reductions” in:1. Rice productivity growth (around 1% per year at
present period compared to 2% in the early green revolution era);
2. Rice area due to economy transformation 3. Water resources (competition by other sector, climate
change)4. Labor for rice farming due to change labor profile in
rural areas (aging farmers, shortage of skilled labor)oChange in diet requirement (more demand of high quality rice)oPrice of rice affected by other unpredictable factors
Annual growth rate (%) of rice area, yield and production in Asia in 1971-1991 and 1991-2011
(Based on FAOSTAT)
Future opportunities of rice production in Asia and the Pacific (cont.)
oDrive of increase rice production/supply to meet increased demand of populationoHunger and poverty reduction is still on top of development agenda of the world and in each country (Zero Hunger Challenge advocated by UN)oThe world commitment to tackle the problems of global climate change (Climate Smart Agriculture advocated by UN) oNew technologies (biotechnology, ICT. …) provides opportunities to increase rice productivity and to help produce more with less (inputs and labor) oRice transformation facilitates modernization of rice production, reduction of postharvest loss and improvement of rice value chain.oTrends of promoting global rice trade
FAO formulated A Regional Rice Strategy for sustainable food security in Asia and the Pacific with Vision:
Food-secure, better nourished and prosperous rice farmers and consumers in the Asia/Pacific region who benefit equitably from a vibrant, innovative and transformed rice sector that is more productive, efficient and environmentally sustainable by 2030.(FAORAP, 2014)
Present status of hybrid rice production in Asia and the Pacific
oTotal hybrid rice area: 20 million ha oIncreased rice productivity (averaged 15-20%) and increased rice production facilitating the conversion of the rice land to other agricultural and non agricultural activitiesoIncreased incomes of rice farmers growing HR and HR seed growers as farmersoGenerated additional rural labor involving HR seed production

Trends of HR area, yield and production in some countries
Constraints of hybrid rice development: Technology (cont.)
Limitation of hybrid varietiesoStagnant and inconsistent yields of HR varieties:, low heterosis magnitudeoHR varieties lack other desirable traits to suit to local conditions in term of:
- grain quality- growth duration- tolerance to abiotic and biotic stresses (narrow genetic diversity of male
sterile sources resulted in more susceptibility to pests like BPH, WBPH, BLB, SB…) - ecosystem adaptability (rainfed conditions)
oMany hybrids released but very few hybrids are superior. Lack of desirable japonica hybridsoSignificant improvement of inbred varieties (yield and quality, pest resistance, abiotic tolerance,…)
Constraints of hybrid rice development: Technology (cont.)
Limitations of HR seed production and supplyo Lack of suitable land specialized for hybrid seed production.o Low seed yields due to low outcrossing capability of parents, lack of skilled workers/seed growers, low purity of parental seeds, improper techniques (for example, to synchronize flowering of parents), fluctuation in temperature /rainfall affecting outcrossingo Lack of facilities for seed processing and storageo Domestic production is not sufficient and import dependence.o High seed costoSeed quality problems

Constraints of hybrid rice development: Technology (cont.)
Limitations of grain qualityoPoor grain quality compared to inbred varietiesoNot suited to consumers preference: (for example, low amylose HR in Bangladesh, chalkiness in China, bold grains in Vietnam…) oProcessing preference: low head rice recoveryoNot suited to market demand (more demand of high quality rice, aromatic rice, japonica type,…)Limitations in cultural practicesoImproper crop management required for HR, particularly nutrient and pest management oLarge yield gap between demonstration yields and farmers’ yield of HR oCultivation of HR rice requires additional external inputsoRice ecosystem degradation
Constraints of hybrid rice development: Socioeconomics
oLow paddy price but high input price (rice farmers are not encouraged to invest in rice farming)oLow market price of HR as compared to normal rice
- Poor quality, lack of product brands- Low profits of HR farmers
oFarmers tendency to use their own seeds (seed availability)oLabor profile in the countryside change (high labor cost, labor shortage)oFarmers’ poverty resulted in low response to intensive technologies
Constraints of hybrid rice development: Policy
oIn adequate investment for:- Research and Extension for HR development- Human resources capability building (Education and
Training)- Infrastructure for rice production (irrigation, mechanization,
post harvest…)
oLack of supportive mechanisms for: - Mobilization of private sector and all stakeholders involved- Public and private partnership (Week private sector
participation and public-private partnership) - Encouragement of domestic seed production - Facilitation of technology transfer and germplasm exchange among countries
Constraints of hybrid rice development: Policy (cont.)
oInconstant and inefficient subsidy leading to unsustainable adoption of HR; different level of subsidy by local government within a country
oDifferent treatment between notified HR varieties (Public) and truthfully labelled hybrids from private sector (Indian case)
oLack of consistent and long term HR program
Future opportunities of hybrid rice development
