Sustainable farming, ‘key’ to world free of hunger, malnutrition, says UN agriculture chief

Focusing this year on the links between agricultural trade, climate change and food security, Director-General José Graziano da Silva said in the foreword that “ensuring food security for all is both a key function of, and a challenge for agriculture, which faces ever-increasing difficulties.”

“As populations rise, urbanization increases and incomes grow, the agricultural sector will be under mounting pressure to meet the demand for safe and nutritious food,” da Silva explained.

Turning to the warming planet, he underscored that agriculture is pivotal in helping to sustain the world’s natural resources and biodiversity.He sized up that agriculture must generate decent jobs to support billions of rural people globally, especially in developing countries where hunger and poverty are concentrated.

“Climate change will have an increasingly adverse impact on many regions of the world, with those in low latitudes being hit the hardest,” he said.

The report points out that by the middle of this century, higher temperatures, precipitation changes, rising sea levels, extreme weather events and a likely increase in damage due to pests and disease, will all significantly impact agriculture and food security.

Climate change impacts will be affect different places in different ways, with variations across crops and regions. Arid and semi-arid regions will be exposed to even lower rainfall levels and higher temperatures, lowering crop yields.

Countries in Africa, Asia and Latin America will be disproportionately affected, many of which already suffer from poverty, food insecurity and malnutrition.

Conversely, countries in temperate, largely more-developed areas, may benefit from warmer weather during their growing season, further exacerbating existing inequalities and widening the development gap.

“Unless we take urgent action to combat climate change, we can expect to see a very different global picture of agriculture in the future,” the FAO chief stressed.

The relationship between agricultural trade and food security is increasingly important in both trade and development agendas, with developing countries requiring international support to cope with climate change. 

While international trade can potentially stabilize markets and reallocate food from surplus to deficit regions, Mr. Graziano da Silva emphasized: “We must ensure that the evolution and expansion of agricultural trade is equitable and works for the elimination of hunger, food insecurity and malnutrition globally.”

Against the backdrop that the world’s food system overall in 2050 will need to produce almost 50 per cent more, compared to 2012, according to the report, the sector needs to adjust to climate change effects and reduce greenhouse gas emissions, while meeting a growing demand.

Producing more with less, while preserving natural resources and enhancing the livelihoods of small-scale family farmers, will be a key challenge for the future.

“Developing and implementing policies that shift global agricultural production onto a more sustainable path, protect the most vulnerable countries and regions…will be key if we are to see a world free of hunger and malnutrition by 2030,” concluded the Director-General.
