DHAKA, Bangladesh (CIMMYT) — As wheat farmers in Bangladesh struggle to recover from a 2016 outbreak of a mysterious disease called “wheat blast,” the country’s National Seed Board (NSB) released a new, high-yielding, blast-resistant wheat variety, according to a communication from the Wheat Research Centre (WRC) in Bangladesh.

Called “BARI Gom 33,” the variety was developed by WRC using a breeding line from the International Maize and Wheat Improvement Center (CIMMYT), a Mexico-based organization that has collaborated with Bangladeshi research organizations for decades, according to Naresh C. Deb Barma, Director of WRC, who said the variety had passed extensive field and laboratory testing. “Gom” means “wheat grain” in Bangla, the Bengali language used in Bangladesh.

“This represents an incredibly rapid response to blast, which struck in a surprise outbreak on 15,000 hectares of wheat in southwestern Bangladesh just last year, devastating the crop and greatly affecting farmers’ food security and livelihoods, not to mention their confidence in sowing wheat,” Barma said.

Caused by the fungus Magnaporthe oryzae pathotype triticum, wheat blast was first identified in Brazil in 1985 and has constrained wheat farming in South America for decades. Little is known about the genetics or interactions of the fungus with wheat or other hosts. Few resistant varieties have been released in Brazil, Bolivia and Paraguay, the countries most affected by wheat blast.

The Bangladesh outbreak was its first appearance in South Asia, a region where rice-wheat cropping rotations cover 13 million hectares and over a billion inhabitants eat wheat as main staple.

Many blast fungal strains are impervious to fungicides, according to Pawan Singh, a CIMMYT wheat pathologist. “The Bangladesh variant is still sensitive to fungicides, but this may not last forever, so we’re rushing to develop and spread new, blast-resistant wheat varieties for South Asia,” Singh explained.

The urgent global response to blast received a big boost in June from the Australian Centre for International Agricultural Research (ACIAR), which funded an initial four-year research project to breed blast resistant wheat varieties and the Indian Council of Agricultural Research (ICAR), which also provided grant to kick-start the work in South Asia. Led by CIMMYT, the initiative involves researchers from nearly a dozen institutions worldwide.

Chemical controls are costly and potentially harmful to human and environmental health, so protecting crops like wheat with inherent resistance is the smart alternative, but resistance must be genetically complex, combining several genes, to withstand new mutations of the pathogen over time.

Key partners in the new project are the agricultural research organizations of Bangladesh, including the Bangladesh Agricultural Research Institute (BARI), and the Instituto Nacional de Innovación Agropecuaria y Forestal in Bolivia, which will assist with large-scale field experiments to select wheat lines under artificial and natural infections of wheat blast.

Other partners include national and provincial research organizations in India, Nepal and Pakistan, as well as Kansas State University (KSU) and the U.S. Department of Agriculture-Agricultural Research Services (USDA-ARS). The U.S. Agency for International Agricultural Development (USAID) has also supported efforts to kick-start blast control measures, partnerships and upscaling the breeding, testing and seed multiplication of new, high-yielding, disease resistant varieties through its Feed the Future project.

BARI Gom 33 was tested for resistance to wheat blast in field trials in Bolivia and Bangladesh and in greenhouse tests by the USDA-ARS laboratory at Fort Detrick, Maryland. International partnerships are critical for a fast response to wheat blast, according to Hans-Joachim Braun, director of CIMMYT’s Global Wheat Program.

“Worldwide, we’re in the middle of efforts that include blast surveillance and forecasting, studies on the pathogen’s genetics and biology, integrated disease management and seed systems, as well as raising awareness about the disease and training for researchers, extension workers, and farmers,” said Braun.

With over 160 million people, Bangladesh is among the world’s most densely populated countries. Wheat is Bangladesh’s second most important staple food, after rice. The country grows more than 1.3 million tons each year but consumes 4.5 million tons, meaning that imports whose costs exceed $0.7 billion each year comprise more than two-thirds of domestic wheat grain use.

WRC will produce tons of breeder’s seed of BARI Gom 33 each year. This will be used by the Bangladesh Agricultural Development Corporation (BADC) and diverse non-governmental organizations and private companies to produce certified seed for farmers.

“This year WRC will provide seed to BADC for multiplication and the Department of Agricultural Extension will establish on-farm demonstrations of the new variety in blast prone districts during 2017-18,” said Barma.

As an added benefit for the nutrition of wheat consuming households, BARI Gom 33 grain features 30 percent higher levels of zinc than conventional wheat. Zinc is a critical micronutrient missing in the diets of many of the poor throughout South Asia and whose lack particularly harms the health of pregnant women and children under 5 years old.

With funding from HarvestPlus and the CGIAR Research Program on Agriculture for Nutrition, CIMMYT is leading global efforts to breed biofortified wheat with better agronomic and nutritional quality traits. The wheat line used in BARI Gom 33 was developed at CIMMYT, Mexico, through traditional cross-breeding and shared with Bangladesh and other cooperators in South Asia through the Center’s International Wheat Improvement Network, which celebrates 50 years in 2018.

Stable window 1 and 2 (W1W2) funding from CGIAR enabled CIMMYT and partners to react quickly and screen breeding lines in Bolivia, as well as working with KSU to identify sources of wheat blast resistance. The following W1 funders have made wheat blast resistance breeding possible: Australia, the Bill & Melinda Gates Foundation, Canada, France, India, Japan, Korea, New Zeland, Norway, Sweden, Switzerland, the United Kingdom and the World Bank. The following funders also contributed vital W2 funding: Australia, China, the United Kingdom (DFID) and USAID.

Bangladesh Reduced Number of Poor by 16 million in a Decade

PRESS RELEASE

Bangladesh Reduced Number of Poor by 16 million in a Decade

June 20, 2013

 

DHAKA, June 20, 2013: Bangladesh has made remarkable progress in reducing poverty from 2000 to 2010. The country witnessed steady and continuous decline in the number of poor people over the decade—from nearly 63 million in 2000 to 47 million in 2010. Despite a growing population, the number of poor people declined by 26 percent in 10 years. Poverty declined by 1.7 percentage points per year. The series of external shocks that affected Bangladesh in 2007 and 2008 did not significantly slow down the speed of poverty reduction.

A new World Bank report ‘Bangladesh Poverty Assessment: Assessing a Decade of Progress in Reducing Poverty, 2000-2010’ launched today says during the period 2000-2010 poverty reduction was closely linked to the growth in labor income and changes in demographics. Labor income, both formal and informal, was the dominant factor in higher incomes and lower poverty rates. Fertility rates have been steadily dropping over the last several decades which have resulted in lower dependency ratios and more income per-capita.  The second half of the 2000s saw an escalation of real rural wages but the growth of urban real wages was lackluster.

Against the odds, Bangladesh lifted 16 million people out of poverty in the last 10 years and also reduced inequality; that is a rare and remarkable achievement.’ said Johannes Zutt, World Bank Country Director for Bangladesh.Bangladesh now needs to help a growing population of young adults to obtain the skills and education needed to find productive work and to participate fully in Bangladesh’s social and political life. The World Bank remains committed to working with the Government to help all Bangladeshis escape poverty and share in the country’s growing prosperity.”

The living conditions of the poor also improved in the first decade of 2000. Between 2000 and 2005, a large number of households saw an improvement in terms of the materials used in the constructions of their homes and access to services. Between 2005 and 2010, while the poor continued to improve the quality of their homes, the largest improvements for all households were in terms of the amenities households owned such as television sets and cellular phones.

While overall improvement in wellbeing can seen across all regions, poverty continues to be a daunting problem with about 47 million people still living in poverty and 26 million people in extreme poverty. Poverty in rural areas continues to be more pervasive and extreme than in urban areas, whereas urban areas remain relatively more unequal.

For sustained poverty reduction, Bangladesh needs coordinated multi-sectoral action. To maintain steady growth in income, it will be necessary to promote investments to raise agricultural productivity and also to promote more jobs in manufacturing and service sector.” said Dean Jolliffe, Senior Economist, World Bank and co-author of the report.

From 2000 to 2005, the East (Chittagong, Dhaka and Sylhet) was rapidly improving, while the West (Barisal, Khulna and Rajshahi) had been lagging behind. The poverty pattern changed in the next five years. Between 2005 and 2010, Western divisions experienced larger reductions in poverty and also managed to reach levels of poverty that are closer to those of their Eastern counterparts.

A growing share of women in the labor force contributed to poverty reduction, but further increasing their participation remains a challenge. The labor force participation rate of women, though increased from 25 percent to about 35 percent over the decade, still remains low by international standards.

Bangladesh spends over 2 percent of its GDP on safety net programs but reaches only a third of the poor. Bangladesh needs to focus on improving the linkage between safety nets and poverty reduction through improved design, targeting and timing of safety net responses. For example, the large number of cash allowances could be linked to human capital formation and targeted to the poor. ” said Iffath Sharif, Senior Economist, World Bank and co-author of the report.
