MALNUTRITION: Famine response needs better science communication

Poor communication of drought predictions prevents policymakers from taking action

The Horn of Africa drought exposes the continuing gap between our ability to predict disaster and to take effective humanitarian action.
Earlier this week, the UN declared the drought in southern Somalia had become so bad that it could be officially declared a famine — the first time the word had been applied to this region in almost 20 years.
The news came as little surprise to agencies that had been monitoring the lack of rainfall over the past year, which is partly linked to the La Niña event in the Pacific Ocean. They had predicted that a widescale shortage of food was highly likely to occur.
Despite these warnings, and the efforts of international agencies such as UNICEF to take pre-emptive action, the overall humanitarian response has so far been severely inadequate, and unable to prevent further deterioration in living conditions in the region.
The situation emphasises the gap between our rapidly increasing ability to predict disasters, thanks largely to advances in science and technology, and our capacity to generate the political will to carry out effective mitigation strategies.
One important obstacle is that politicians often feel uncomfortable taking decisions when the science is uncertain. So the way that scientific evidence is communicated by researchers and journalists can make a big difference.
But scientists desperately need better communication techniques to ensure that politicians are alerted to credible evidence of a looming humanitarian disaster. This must include ways of reassuring policymakers that, if predictions do not come true, they will not be rebuked for taking unnecessary (and potentially expensive) action.
And journalists too need to engage politicians much better when reporting the scientific aspects of disasters to help ensure that timely action is taken.

Satellites improve prediction
The good news is that modern technology, and in particular the widespread use of remote sensing satellites, has given us the power to predict disasters with far greater accuracy than ever before.
Admittedly there is some way to go before many African governments — with some notable exceptions, such as Nigeria and South Africa — are convinced of the need to make their own substantial investments in this technology.
But this failure has been more than compensated for by the commitments of international and developed-country organisations. Indeed, our ability to predict disasters is one of the major social benefits from investment in space technology over the past 50 years.
Weather prediction is not alone — advances have also been made in predicting volcanic eruptions, widespread flooding, and earthquakes and related tsunamis. In each case, monitoring now has the capacity to save thousands of lives.

Lost opportunities
Too often, however, advanced technical skills outstrip the humanitarian community's ability to make full use of the information that these technologies generate, leading inevitably to lost opportunities.
As Chris Funk, a climatologist with the USAID-funded Famine Early Warning Systems Network (FEWS NET), told SciDev.Net last week, the organisation's experts were frustrated that their early warnings of the drought in Somalia went largely unheeded.
Not enough had been done to ensure that the information was put to good use: "The technology has outpaced the response systems," said Funk.
The problem is not simply one of communication. For example, FEWS NET's food security alerts, one-page briefing documents, are a model of precise, authoritative information directed at decision-makers.
Rather, the challenges are to get decision-makers to take this type of information on board, and to develop timely and effective response mechanisms.

Reaching the policymakers
Considerable research is already being carried out into the ways that policymakers assimilate and use scientific evidence in the decision-making process. [1] But it is clear that much more remains to be done, particularly where such evidence is uncertain (as is frequently the case when it is based on modelling).
In particular, we need to focus on the way that the political process handles statistical evidence, given that this is seldom definitive and can often be interpreted in different ways.
For example, the public in countries likely to be affected can be encouraged to accept that the costs of inaction (such as not taking steps to mitigate the impacts of a predicted drought) can far outweigh the costs of taking action that later proves to be unnecessary. But the fact that the costs can fall on different populations complicates matters further.
More research is also needed into the most effective ways of linking warning signals to recommendations for action. Policymakers frequently turn to scientists to ask for guidance when faced with uncertain evidence, and the scientific community has a responsibility to explore and lay out the options — and their implications — even if the final decision must rest in the hands of politicians.
Journalists have a key role to play in all of these processes. One of their tasks is to raise the alarm among policymakers and the public about impending disasters — providing that this is done in a responsible, evidence-based manner.
Another is to find out from scientists and other stakeholders what the policy options are, and ensure that politicians are aware of them. Journalists are also in a good position to monitor whether politicians are taking action, and to expose those who fail to do so.
Each of these tasks requires confidence in reporting on evidence that may lack certainty. But a lack of responsible reporting, or of effective communication about impending disasters, may translate into a lack of mitigating action by politicians, with potentially devastating consequences.

MALNUTRITION: Argentine farmers halt grain sales

17 Jan 2011 Strike over export curbs rekindles a dispute that helped drive global grains prices to record highs three years ago.

Argentine farmers have halted sales of wheat, corn and soy in a strike over export curbs, rekindling a dispute that helped drive global grains prices to record highs three years ago.
The seven-day protest by growers, which started on Monday, could fuel supply concerns just as dry weather linked to the weather phenomena La Nina worsens the outlook for soy and corn production.
Farmers in Argentina, one of the world's biggest food suppliers, have been at odds with the government for years over export curbs aimed at taming inflation and guaranteeing affordable supplies of everyday staples.
They say the system of wheat and corn export quotas lets millers and exporters pay farmers low prices, and have urged the government to scrap the caps.
"These distortive, interventionist measures have been repeated for several harvests in recent years," Hugo Biolcati, leader of the Argentine Rural Society, said when the country's four farming groups announced the strike last week.
The protest is bad news for Christina Fernandez, the president, nine months from the October election in which she is widely expected to seek re-election.
The wave of farmer strikes that began in March 2008 over a tax hike on soy exports battered her popularity, hit Argentine asset prices and disrupted grains shipments at the height of the soy harvest.
However, the impact of this week's protest on grains prices will likely be muted because soy and corn harvesting has yet to begin.

La Nina effect
Government officials condemned the farmers for calling another strike, even warning of possible flour shortages, although Julian Dominguez, the agriculture minister, acknowledged wheat farmers' problems.
The government is taking steps to ensure mills and exporters paid fixed local wheat prices to farmers and punish those that did not.
Dominguez advocated an even stronger state role in the country's multibillion-dollar grains trade during a weekend newspaper interview.

La Nina
La Nina is a weather phenomena causing abnormal cooling of the central and eastern Pacific.
Generally, La Nina will mean that parts of the world that normally experience dry weather will be drier and parts with wet weather will be wetter.
La Nina translates from Spanish as "The Little Girl" and is meteorologically the opposite of the El Nino.
La Ninas occur on average every three to five years and will typically last for up to 12 months.
"What the grains trade needs in Argentina is the presence of the state in the market - going back to the model of the Federal Grains Agency or National Grains Board, a body made up of the grains exchanges, the state, the co-operatives, that can ensure the market works for farmers," he was quoted as telling Tiempo Argentino newspaper.
Low rainfalls began worrying the agriculture industry in December in response to La Nina diminishing rain over Argentina. Weather fluctuations have helped lift corn and soy prices close to their record highs of 2008 in recent weeks.
Soaring prices are good news for farmers, but the parched soils are worrying farmers across Argentina's famous Pampa plains.
Argentina is the world's leading exporter of soyoil and soymeal and the third-largest global supplier of soybeans. It is also a major wheat supplier and the second-largest corn provider.
Soy exports brought in $12.98bn in 2009, accounting for 23 per cent of total export earnings.
But this year, soybean group Acsoja has estimated that production would fall by 13 per cent as a result of water shortages.
La Nina, which affects weather patterns across the Asia-Pacific region and in particular the amount of rainfall, is threatening to expand drought in the Americas while bringing more devastating rains to Australia, according to the US Climate Prediction Centre.
La Nina-inspired rainfall has pushed Australia into recording its third wettest year on record in 2010 while causing drought in grain-growing areas of the southern US as well as in Brazil and Argentina.
