UN: Without urgent action, climate change will push millions into hunger

Farmers urgently need help to adapt their methods of growing food if the world is to curb greenhouse gas emissions and prevent climate change pushing millions into hunger and poverty, the UN Food and Agriculture Organization (FAO) said on Monday.

Small farmers who produce the bulk of food in developing countries are some of the most vulnerable to changes in climate and need help adapting to a warming planet, FAO said in a report, Reuters reported.

Climate is expected to hit crop yields and livestock production and make the price of food more volatile, putting poor families at greater risk of hunger, the UN agency said.

"Unless action is taken now to make agriculture more sustainable, productive and resilient, climate change impacts will seriously compromise food production in countries and regions that are already highly food-insecure," FAO Director General Jose Graziano da Silva said in the report.

"Hunger, poverty and climate change need to be tackled together. This is, not least, a moral imperative as those who are now suffering most have contributed least to the changing climate," Graziano da Silva said.

The UN agency estimates that, with climate change, an additional 42 million people will be vulnerable to hunger in 2050. This figure does not include the growing numbers affected by extreme weather events.


El Nino effect


These climate shifts are reinforced by the recurring El Nino weather pattern, which happens when water in the Pacific Ocean becomes abnormally warm, altering global weather patterns.

More than 60 million people – two-thirds of them in east and southern Africa – faced food shortages this year because of droughts linked to El Nino.

Smallholder farmers in Africa and Asia are already affected by rising temperatures, changes in rain patterns, frequency of droughts, and rising sea levels.

"Larger farmers have the means to cope with those temporary threats, whereas small farmers can be totally wiped out because they don't have the savings ... or assets," Stamoulis said.

Climate change is also expected to affect the nutrient content of food. The higher the concentration of CO2 in the atmosphere, the lower the nutritional content of crops like wheat, Stamoulis said.

Agriculture, forestry and changes in land use together produce 21 percent of global greenhouse gas emissions, making them the second largest emitter after the energy sector.

The raising of livestock alone produces nearly two-thirds of agriculture emissions, FAO said on Monday.

The figures do not include emissions produced from farm machinery, or in the transport, processing and storage of food.

"Those emissions come from the way we plough our soil, fertilize our crops, the way we use chemicals and manure, the way we raise our livestock, and the way we ... deforest," said Stamoulis.

"If we don't change the way we do business ... every target ... to stabilize the climate will be missed," he added.

A global agreement to tackle climate change, reached in Paris last year, will take effect on Nov. 4. Work is due to start at UN climate talks in Morocco next month to hammer out the rules for putting the accord into practice.

The need for more sustainable agricultural practices will be an important part of that discussion, Stamoulis said.
