Unless global policymakers redouble their efforts to properly support a strategy to ensure a future food supply, the current hunger crisis threatens only to get worse.
A gathering of more than 500 scientists at the 2015 International Wheat Conference in Australia, provides an opportunity to revisit these matters.
Already almost 800 million people worldwide — about 1 in 9 people — are undernourished and do not get enough food to eat to lead a healthy active life, according to the U.N. Food and Agriculture Organization.
By 2050, the current global population of 7.3 billion is projected to grow 33 percent to almost 10 billion, according to the United Nations.
Agriculture and food security experts have an appeal to governments, nongovernmental organizations, the private sector, research institutes and consumers: work together to deliver sustainable food security solutions for the world.
The majority of hungry people live in developing countries where almost 14 percent of the population is undernourished, FAO reports in its 2015 “State of Food Insecurity in the World” report. The current refugee crisis in Europe provides dramatic evidence that wealthy countries must increase investments that will help promote food security and political stability in poor countries.
Bolstering food security
Investments in agricultural science must be at the top of the list. Wheat currently provides 20 percent of calories and 20 percent of protein to the global human diet. In order to keep up with population growth, we must increase wheat production from the current annual 700 million metric tons a year to 1 billion. We also face the threat of climate change-related global warming.
To date, however, scientists have been unable to sufficiently increase yields to meet demand through hybridization. Production must grow 70 percent over the next 35 years — an achievable goal if annual wheat yields are increased from a current level of below 1 percent to at least 1.7 percent. It is time to invest in biotechnology to ensure yields can provide nourishment for an ever-hungrier planet.
Simultaneously, we must maintain balance in the food chain and restore depleted carbon in the soil. Such concerns as disease resilience, seed diversity, water management and micronutrient imbalance must be tackled.
Governments and the private sector must more fully support research efforts to accelerate the development of new wheat varieties or face the risk of further global insecurity related to price instability, hunger riots, related conflict and refugee crises.
We must be guaranteed research funding to solve the puzzle of how to achieve higher yield gain. Combining biotechnology with conventional breeding methods may be the only means of helping smallholder farmers and large corporate farm systems avert global famine.

Sanjaya Rajaram is the 2014 World Food Prize laureate for scientific research that led to an increase in world wheat production by more than 200 million tons. He worked at the International Maize and Wheat Improvement Center for 33 years and International Center for Agricultural Research in the Dry Areas for eight years. The wheat varieties he developed are now grown on 58 million hectares worldwide. It is estimated that these varieties provide wheat to more than 1 billion people a year.
