ALEPPO,
SYRIA. Wheat experts from 26 countries warn that rapidly-moving,
wind-borne transboundary wheat diseases continue to threaten food
security and wheat genetic diversity worldwide - particularly in the
ancient breadbasket stretching from the Middle East to India - as
they vowed new action to isolate and interrupt the steady march of
dangerous wheat rust diseases.
The proposed global rust reference laboratory, which was embraced
in Aleppo at the Borlaug Global Rust Initiative (BGRI) Coordination
Conference, will house a unique collection of all the world's known
races of stem rust and yellow rust in a secure containment facility.
Dr Mahmoud Solh, Director General of the International Center for
Agricultural Research in the Dry Areas (ICARDA) a BGRI partner and
conference host, said such a global reference laboratory will be used
as a repository for identifying new virulent races of the pathogen,
as a site for race identification and analysis, and as an important
location for training scientists from national programs.
Dr Solh said these highly mobile, wind-borne, transboundary wheat
diseases have the potential to endanger global production of a crop
that feeds 2 billion people.
"For example, the black stem rust Ug99 is alarming because 80
percent of the world's wheat varieties are susceptible," said
Dr. Solh. "But other types of wind-borne wheat rust could quickly
affect the food security of millions of households in poor rural areas
where wheat is literally the bread of life."
The Declaration issued at the end of the Aleppo meeting referred to
the increasing danger stem rust now poses to wheat production and
diversity, especially as the mapped trajectory of the destructive
and virulent strain of black stem rust Ug99 shows it moving into the
highly productive wheat belt that stretches from the Middle East to
India. This area includes the land where wheat first emerged as a
domesticated crop.
"The Middle East is the cradle of agriculture - where wheat cultivation
began," the Declaration states. "This area is a great reservoir
of breeding material and wild relatives of wheat that are vital for
developing wheat varieties to combat many threats including drought
(and) climate change
."
The Declaration also cites the need to "develop early warning,
seed production and delivery systems, and collaboration to allow us
to anticipate wheat rust threats in the future as well as manage existing
threats such as Ug99." Discussions at the conference identified
key gaps in the current knowledge of rust diseases, and opportunities
to use biotechnology and modern communications capabilities to track
and combat rust diseases faster and more efficiently.
Dr Ronnie Coffman, vice-Chair of the Borlaug Global Rust Initiative
(BGRI), said the conference is part of a series of coordinated actions
focused on transboundary wheat rust diseases that have flowed from
the BGRI, whose permanent members include ICARDA, CIMMYT (two of the
CGIAR centers), FAO, the Indian Council for Agricultural Research
(ICAR), and Cornell University.
"The BGRI is named after Nobel Prize Laureate Norman Borlaug,
whose work (decades ago) in combating an earlier invasion stem rust
is credited with helping launch the Green Revolution. It is Borlaug's
call to action that has rallied a diverse array of scientists, governments
and international institutions to combat this new generation of wheat
rusts," Dr Coffman said.
BGRI activities are funded by an array of donors including the USAID,
CIDA-Canada, AFESD-Arab Fund, IFAD, the Indian Council for Agricultural
Research (ICAR), FAO and The Bill & Melinda Gates Foundation (supporting
the largest project on Durable Rust Resistance in Wheat) and other
donors. In addition, national programs have been investing significantly
through in-kind contributions to combat wheat rusts.
The BGRI, coordinated by Cornell University, now includes researchers
and government agriculture officials from every wheat-growing region
in the world.
Dr Coffman said that efforts in BGRI started in 2005 and already resistant
material has been identified through the BGRI partnership, and resistant
varieties have been released in Ethiopia and Egypt.
However, he warned: "We are running against time to ensure development
of durable resistant varieties and to fast-track seed production and
delivery systems to reach farmers quickly, and stay ahead of these
fast-moving wind-borne diseases. In addition to our technical work,
strong political support is needed at national, regional and international
levels."

About
ICARDA: Established
in 1977, the International Center for Agricultural Research in the
Dry Areas (ICARDA) is one of 15 centers supported by the CGIAR. ICARDAs
mission is to contribute to the improvement of livelihoods of the
resource-poor in dry areas by enhancing food security and alleviating
poverty through research and partnerships to achieve sustainable increases
in agricultural productivity and income, while ensuring the efficient
and more equitable use and conservation of natural resources.
ICARDA has a global mandate for the improvement of barley, lentil,
barley and faba bean, and serves the non-tropical dry areas for the
improvement of on-farm water use efficiency, rangeland and small-ruminant
production. In the Central and West Asia and North Africa (CWANA)
region, ICARDA contributes to the improvement of bread and durum wheats,
kabuli chickpea, pasture and forage legumes, and associated farming
systems. It also works on improved land management, diversification
of production systems, and value-added crop and livestock products.
Social, economic and policy research is an integral component of ICARDAs
research to better target poverty and to enhance the uptake and maximize
impact of research outputs.
About the CGiAR: The Consultative Group on International Agricultural
Research (CGIAR) (www.cgiar.org) is a strategic alliance of countries,
international and regional organizations, and private foundations
supporting15 international research centers that mobilizes cutting-edge
science to promote sustainable development by reducing hunger and
poverty, improving human nutrition and health, and protecting the
environment. |
