The work of FAO is built on an overarching goal of eradicating hunger, which can be
achieved by accelerating the shift toward sustainable food consumption and production
systems, promoting greater fairness in the global and national management of food
systems, expanding South-South Cooperation and speeding the Organization’s decentralization so FAO can bring its expertise closer to the field. Together, these objectives
underpin FAO’s work with governments and public and private sector partner organizations, which develops national capacity to leverage public goods.
To meet the demands posed by major global trends in agricultural development and
challenges faced by member nations, FAO has identified key priorities on which it is
best placed to intervene. A comprehensive review of the Organization’s comparative
advantages was undertaken which enabled strategic objectives to be set, representing
the main areas of work on which FAO will concentrate its efforts in striving to achieve
its vision and global goals. Those strategic objectives can be summarized as follows:
•
Help eliminate hunger, food insecurity and malnutrition
•
Make agriculture, forestry and fisheries more productive and sustainable
•
Reduce rural poverty
•
Enable inclusive and efficient agricultural and food systems
•
Increase the resilience of livelihoods from disasters
In implementing this strategy rice remains a high priority for FAO. Rice is not only important for food security, but is also an important economic commodity. Rice diversity is
furthermore important for plant breeding and nutritional security, and rice fields host a
wide range of terrestrial and aquatic biodiversity. This places rice as an important crop
in many ways.
FAO has always supported its member nations’ efforts to increase rice production. FAO
has been leading and partnering in global, regional and national efforts to promote action in matters relating to the production, conservation, distribution and consumption of
rice.
The recent progress, including the release of new high yielding varieties of rice, has allowed from 2007-2012 an increase by about 30% of the rice production in Sub-Saharan
Africa. This shows the Africa potential for bridging the production gap, a potential which
is currently largely untapped. FAO and partners are determined to play a key role in
realizing the promise of an efficient and competitive rice sector for Africa.

Bill & Melinda Gates Foundation
Guided by the belief that every life has equal value, the Bill & Melinda Gates
Foundation works to help all people lead healthy, productive lives. In developing
countries, it focuses on improving people’s health and giving them the chance to
lift themselves out of hunger and extreme poverty. In the United States, it seeks
to ensure that all people—especially those with the fewest resources—have access
to the opportunities they need to succeed in school and life.
Based in Seattle, Washington, the foundation is led by CEO Jeff Raikes
and Co-chair William H. Gates Sr., under the direction of
Bill and Melinda Gates and Warren Buffett.

The Global Rice Science Partnership (GRiSP), a research program of the CGIAR, represents
for the first time ever a single strategic and work plan for global rice research. GRiSP brings
together hundreds of scientists to embark on the most comprehensive attempt ever to harness
the power of science to solve the pressing development challenges of the 21st century. Cuttingedge science is deployed to develop new rice varieties with high yield potential and tolerance
to a variety of stresses such as flooding, salinity, drought, soil problems, pests, weeds, and
diseases. Improved natural resources management practices will allow farmers to fully realize
the benefits of such new varieties on a sustainable basis while protecting the environment. Future
rice production systems are designed to adapt to climate change and to mitigate the impacts
on global warming. Policies conducive to adoption of new varieties and cropping systems will
be designed to facilitate the realization of development outcomes. GRiSP will train future rice
scientists and strengthen the capacity of advisory systems to reach millions of farmers. For
impact at scale, GRiSP scientists collaborate with hundreds of development partners from public
and private sectors across the globe.
GRiSP was launched in 2010 and is coordinated by the International Rice Research Institute
(IRRI; the lead institute), Africa Rice Center (Africa Rice), International Center for Tropical
Agriculture (CIAT), Centre de Cooperation lnternationale en Recherche Agronomique pour le
Développement (Cirad), L’lnstitut de Recherche pour le Développement (IRD), and the Japan
International Research Center for Agricultural Sciences (JIRCAS). Together, they align and bring
to the table consortia, networks, platforms, programs, and collaborative projects with over 900
partners from the governmental, nongovernmental, public, private, and civil society sectors.
During the Africa Rice Congress and the Global GRiSP Forum 2013 in Yaoundé, Cameroon,
GRiSP scientists will share and discuss the progress made in the African rice sector to date.
I look forward to sharing in these debates that will surely be exciting!
Bas Bouman
Director, GRiSP
