Global agricultural production is growing steadily across most commodities, reaching record levels in 2017 for most cereals, meat types, dairy products and fish, while cereal stock levels have climbed to all-time highs, according to an annual report from the Organisation for Economic Cooperation and Development and the UN's Food and Agriculture Organisation.

The report stresses that agricultural trade plays an important role in promoting food security, underscoring the need for an enabling trade policy environment.

OECD-FAO Agricultural Outlook 2018-2027 sees weakening growth in global demand for agricultural commodities and food, while anticipating continuing productivity improvements in the sector. As a result prices of main agricultural commodities are expected to remain low for the coming decade.

The report, presented in Paris by OECD Secretary-General Angel Gurría and FAO Director General José Graziano da Silva, attributes the demand slowdown to a deceleration of demand growth in major emerging economies, stagnating per capita consumption of staple foods, and a further gradual decline in global population growth rates. 

The Outlook finds that global agricultural and fish production is projected to grow by around 20% over the coming decade, but with considerable variation across regions. Strong growth is expected in developing regions with more rapid population growth, including Sub-Saharan Africa, South and East Asia, and the Middle East and North Africa. By contrast, production growth is expected to be much lower in developed countries, especially in Western Europe.

The Outlook projects that the weakening of global demand will persist over the coming decade, sapped by declining population growth, flat levels of per capita consumption for staple foods and slowing demand growth for meat products. Declining demand growth for meat products will put a brake on the demand for cereals and protein meal used in animal feed. 

With slower consumption and production growth, agricultural and fish trade are projected to grow at about half the rate of the previous decade. Net exports are expected to increase from land-abundant countries and regions, notably the Americas. Countries with high population growth, in particular in the Middle East and North Africa, Sub-Saharan Africa and in Asia, will see rising net imports.

"While overall exports from countries and regions abundant in land are set to increase, notably in the Americas, many poorer countries with rising populations and limited land resources will be increasingly dependent on food imports to feed their people," said Mr Gurría. "It will be essential that exporters and importers alike have access to an open and predictable trade policy environment."

"The Green Revolution of the last century largely increased hte world's capacity to feed itself but now we need a sustainability revolution," said FAO Director-General José Graziano da Silva. "This includes tackling high-input and resource-intensive farming systems that impose a high cost to the environment. Soil, forests, water, air quality and biodiversity continue to degrade. We need to adopt sustainable and productive food systems that offer healthy and nutritious food, while also preserving the environment and biodiversity."

Demand for cereals and vegetable oil  for the production of biofuels is expected to be largely unchanged over the forecast period, in contrast with the past decade, when biofuels expansion led to more than 120 million tonnes of additional cereals demand, predominantly maize. With existing policies in developed countries unlikely to support biofuels expansion, most demand growth will come from developing countries that have introduced policies favouring biofuel use.  In particular, the use of sugarcane for biofuel production is expected to increase.
