UN official underlines link between food security and climate change

 

Ensuring global food security while striving to save the Planet from damage are the greatest challenges of this century, a senior United Nations official said today, stressing the need to enable smallholder farmers to become more resilient to climate change and to produce more food in ways that are environmentally sustainable.

“There is no trade-off between feeding people and saving our Planet,” said Kanayo F. Nwanze, the President of the UN International Fund for Agricultural Development (IFAD), who is attending the UN Climate Change Conference in Durban, South Africa.

“It is clear that food security and climate change, humanity’s two greatest challenges in the 21st century, are inextricably linked.”

According to IFAD, the world’s 500 million smallholder farms will have to significantly increase production over the next four decades to keep pace with a growing global population. They are required to do that in the face of more frequent extreme weather events and shifting weather conditions caused by climate change.

Prior to his departure for Durban, Mr. Nwanze stressed that despite the slow pace of climate negotiations, IFAD is observing “significant, tangible changes” in developing countries towards sustainable agriculture.

“Out in their fields, farmers are already adapting to the changing climate and realizing that they must respect and preserve the environment if they are to feed their families and produce a surplus for markets,” he said. “And policymakers at the country level are citing the impact of extreme weather on their crop production and asking for climate change to be addressed in rural development projects.”

Mr. Nwanze noted that global investment in agriculture had dropped by half over the past 30 years, and called for greater efforts towards expanding public investment in research to build farmers’ resilience to climate change and to support their adoption of sustainable agricultural practices.

IFAD-supported initiatives in Burkina Faso, China, Ethiopia, Peru and elsewhere are showing success in helping poor farmers increase their productivity and incomes. The farmers make maximum use of natural processes, thus reducing the need for environmentally harmful external inputs.

“There is already a scaling up of sustainable agricultural practices in many parts of the world,” said Mr. Nwanze. “What we need now is a rapid acceleration of these changes so that smallholder farmers can successfully feed their families, connect to markets and contribute more to global food production,” he added.

Meanwhile, IFAD, the UN Food and Agriculture Organization (FAO) and UN World Food Programme (WFP) have assisted over 22 million people hardest hit by the global food price crisis thanks to generous funding from the European Union’s Food Facility (EUFF), demonstrating that investing in agriculture and nutrition improves global food security.

The combined effects of high food prices in 2007-2008 and the global financial and economic downturn pushed millions of people into poverty and hunger. By the end of 2008, when the number of undernourished people neared one billion, the EU launched the €1 billion facility.

Set up in close collaboration with the UN High-Level Task Force on the Global Food Security Crisis, EUFF channelled some €367 million through FAO, IFAD and WFP to bridge the gap between short-term emergency needs and longer-term development by boosting agricultural production and productivity in countries hardest hit by the crises, the three agencies said in a joint statement.

The reality of adapting to uncertain climate forecasts

   

Imagine spending millions of pounds on a barrier to defend thousands of homes from a river bursting its banks but not being totally sure how high it might rise.

Think of expanding a reservoir to hold more water for a rapidly growing population but without clear advice on how rainfall patterns may shift and affect supplies.

Spare a thought for the wine-maker trying to decide which variety of grape to plant knowing that it might take five years to see if a new one thrives.

These are the challenges faced by everyone planning for projects where the future climate may have potentially serious implications.

In the jargon, this is known as "climate adaptation" - but it is easier talked about than acted upon because the forecasts are so uncertain.

The basic assumption, based on computer models, is that Britain will experience warmer, drier summers and milder, wetter winters in the decades ahead.

But there are large uncertainties about what may happen and translating sweeping generalisations into meaningful reality on the ground is difficult.

Climate scientists admit their models are too coarse to provide a detailed guide, especially given that British weather is so changeable as it on the front-line of different air masses.

So how much faith can be put in these predictions and is it worth spending serious money acting on them?

According to Lord Krebs, who led a study into adaptation for the Climate Change Committee - the official body advising the government, the message is clear:

"I don't think there's a need to panic now," he told me.

"There are many decisions which we can put off for the future.

"But if we look at long term decisions, decisions with a long term impact, if we don't get it right now we could be sleepwalking into a disaster for future generations.

"This is not a panic button but it's saying let's be clear-sighted about the future impacts of climate change."

Going with the flow

In practice, that can mean spending a bit more money now to make it easier to respond more quickly in the years ahead.

One example is in Nottingham, which was severely flooded by the River Trent in 2000, where the Environment Agency is investing in a defence scheme.

I watched pile-drivers hammering huge steel sheets into the mud as part of a 27km-long barrier to protect 16,000 homes.

Climate forecasts suggest that rainfall may increase by 25-30% by 2050 and that the flow of the river could increase by up to 30% in the winter but there is no certainty about this.

If the agency followed this advice to the letter the flood wall would be another 25cm higher - at an extra cost of £5million.

Instead the foundations being laid are slightly stronger than needed so that an extra topping can be added if needed in future.

John Curtin, of the Environment Agency, explained that "we've designed this scheme so we're not wasting money now but we can adapt if we need to.

"We want to make sure we can adapt if climate change materialises, or if it doesn't.

"The threat might not be that bad but we can adapt if it is."

Climate confusion

In Essex, the driest county in the UK, a slightly different approach is taken by the water company, Essex & Suffolk Water.

In one of the country's largest construction projects, Abberton Reservoir is being expanded to hold more water.

It is part of a scheme including a system to channel water from as far away as Norfolk and store it locally.

The main driver is the rapid rise in population in the region rather than any response to climate forecasts.

In the view of Martin Lunn of Essex & Suffolk Water, climate models are "not something that we could plan against - they're not accurate enough, the science isn't there for small areas like Essex or even East Anglia.

"We're not ignoring them, but we're not spending money on them. We are aware of the changes there could be - lower river flows, hotter summers, wetter winters.

"But we have to be careful until the science is more definite or we'd risk wasting money."

In Gloucestershire too, at the Three Choirs Vineyard, the prevailing view is one of confusion about what climate change might mean.

Martin Fowke says that although temperatures have become warmer and it's now possible to make red wine, usually only possible in warm conditions, but "it's almost impossible to understand what could happen next.

"For every report you hear saying global warming happening at a certain rate, the next day there's someone saying something completely different.

"We have to take a fairly sensible route through the middle at the moment. We have to go on gut instinct which tells me we're certainly going to need some new varieties but we're not going to suddenly grub up whole vineyard."

The gamble for wine-makers is whether to plant popular varieties of grape that might not do well if the conditions do not change as forecast, and it might take five years to know.

The government is anxious for companies and organisations to be alert to the risks of climate change and to adapt to them.

But in many cases that is easier said than done - until the forecasts become more certain.
