Scientists sequence potato genome

Scientists sequence potato genome

New potatoes The humble spud provides the world's fourth-largest crop

Related Stories

An international team has uncovered the full DNA sequence of the potato for the first time.

The breakthrough holds out the promise of boosting harvests of one of the world's most important staple crops.

Researchers at the James Hutton Institute in Dundee, which contributed to the work, say it should soon be possible to develop improved varieties of potato much more quickly.

The genome of an organism is a map of how all of its genes are put together.

Each gene controls different aspects of how the organism grows and develops.

Slight changes in these instructions give rise to different varieties.

Each individual has a slightly different version of the DNA sequence for the species.

Professor Iain Gordon, chief executive of the James Hutton Institute, said decoding the potato genome should enable breeders to create varieties which are more nutritious, as well as resistant to pests and diseases.

Colour and flavour

He hopes it will help meet the challenge of feeding the world's soaring population.

The research is far from complete. Analysing the genetic sequence of the plant will take several more years.

At the moment it can take more than 10 years to breed an improved variety.

By locating the genes that control traits like yield, colour, starchiness and flavour, the research should make it possible to develop better spuds much more quickly.

Potatoes provide the world's fourth-largest crop, with an annual, global yield of 330m tonnes.

Auditors criticise EU farm payment system

Auditors criticise EU farm payment system

Farming near Rennes, northern France - file pic A farm near Rennes: France gets the biggest portion of EU agricultural subsidies

Related Stories

The EU's main audit body says agricultural subsidies - the biggest item in the EU budget - often go to people who do little or no farming.

A new report by the European Court of Auditors complains of deficiencies in the Single Payment Scheme (SPS), which distributed about 29bn euros (£26bn) of subsidies in 2009.

It says payments "have become divorced from current farming conditions".

The EU is considering how to reform its Common Agricultural Policy (CAP).

The auditors have made various recommendations to the European Commission aimed at improving the SPS - the biggest area of spending in the CAP.

They say the SPS ought to direct aid to "active" farmers and provide more balanced funding so that a small number of big landowners no longer get the lion's share.

They also call for clearer definitions of land eligible for subsidies and of farming activities.

The report complains that the 17 EU countries applying the SPS use about 20 different variants of the payment scheme, making it too complex.

Absentee farmers

The SPS does not operate in 10 EU countries, which joined the EU in 2004 and 2007. All 10, except Cyprus, are former communist countries and they use a different system of farm support, called SAPS.

The auditors say the SPS has encouraged farmers to respond better to market demand and has benefited EU agriculture as a whole.

But they say the way the scheme's beneficiaries were defined "permitted persons or entities not, or only marginally, engaged in an agricultural activity to benefit from SPS payments".

In some cases landowners have carried on receiving the payments even though their land is worked by tenant farmers who do not get the subsidy.

In the UK the auditors found some individual beneficiaries receiving up to 1m euros annually or even more in SPS aid without having any agricultural activity on their land.

The report also highlights examples of non-agricultural land qualifying for SPS payments in France, Italy and Spain.

The European Commission has said EU farm spending should no longer be based on previous subsidy levels for farmers.

But the commission believes subsidies are still needed to protect Europe's food supplies and rural diversity. The proposals are contained in an EU blueprint for farming beyond 2013.

surge of interest in foreign investment in agricultural land

the challenge
The recent surge of interest in foreign investment in agricultural land has aroused substantial international concern. Certainly, complex and controversial economic, political, institutional, legal and ethical issues are raised in relation to property rights, food security, poverty reduction, rural development, technology and access to land and water. On the other hand, lack of investment in agriculture over decades has meant continuing low productivity and stagnant production in many developing countries. Lack of investment has been
identifed as an underlying cause of the recent food crisis and the diffculties
developing countries encountered in dealing with it. FAO estimates that gross annual investments of USD 209 billion are needed in primary agriculture and downstream services in developing countries (this in addition to public investment needs in research, infrastructure and safety nets) to meet global food needs in 2050. Developing countries’ own capacity to
fll that gap is limited. The share of public
spending on agriculture in developing countries has fallen to around 7 percent,
even less in Africa, and the share of offcial
development assistance going to agriculture has fallen to as little as 3.8 percent in 2006. Commercial bank lending going to agriculture in developing countries is also small – less than 10 percent in sub-Saharan
Africa and microfnance loans, while indispensable, have not proved suffcient
to agricultural investment needs. Private
investment funds targeting particularly African agriculture are an interesting recent development but actual investments are
still small. Given the limitations of alternative sources of investment fnance, foreign direct
investment in developing country agriculture could make a contribution to bridging the investment gap and realizing the hunger and poverty eradication goals. The question therefore is not whether foreign direct investment should contribute to meeting investment needs but how its impact can
be optimized to maximize the benefts
and to minimize the inherent risks for all involved. To answer that question we need to understand what is happening in foreign investment and why.
What do We knoW about reCent foreign investments in developing Country agriCulture?
Unfortunately, there are no detailed data on the extent, nature and impacts of these investments: international investment statistics are too aggregated and little is
divulged by those involved in specifc cases.
Much information is anecdotal, probably
exaggerated and diffcult to verify. However,
from what limited information is available, a number of observations can be made:
Foreign direct investment (FDI) in developing country agriculture does appear to have increased in the last two years, although the number of projects actually implemented is less than the number being planned or reported in the
media. Inward FDI stock in agriculture in 2007 stood at some USD 32 billion, four times higher than in 1990.
The infow of FDI into agriculture amounted
to more than USD 3 billion per year by 2007, compared to USD 1 billion in 2000. If food and beverages are included, the
fow rises to USD 7 billion in 2007.
The main form of recent investments is purchase or long-term leasing of agricultural land for food production. The area of land acquired in Africa by foreign interests in the last three years is estimated at up to 20 million hectares.
The major current investors are the Gulf
States but also China and South Korea. The main targets for recent investment are countries in Africa but there are also investments in Southeast Asia and South America.
Investors are primarily private sector but governments and sovereign wealth funds
are also involved in providing fnance and
other support to private investors or directly.
Private sector investors are often investment or holding companies rather than agro-food specialists, which means that necessary expertise for managing complex large-scale agricultural investments needs to be acquired.
In host countries it is governments who are engaged in negotiating investment deals.
foreign direct investment – win-win or land grab?Some baSic factS
Current investments differ from the recent pattern of foreign direct investment in several respects: they are resource-seeking (land and water) rather than
market-seeking; they emphasize
production of basic foods, including for animal feed, for repatriation rather than
tropical crops for commercial export;
they involve acquisition of land and actual production rather than looser forms of joint venture.
Key issues
Why foreign investment?
A major underlying driver of the recent upturn in investments, which perhaps differentiates it from the normal run of foreign investments, is food security. This
refects a fear arising from the recent high
food prices and policy-induced supply shocks, notably the result of export controls, that dependence on world markets for food supplies has become questionable. For those countries facing worsening land and water constraints
but with increasing populations, incomes and urbanization, and hence increasingly dependent on imported food, these fears provoked a serious reassessment of their food security strategies. Investing in producing food in countries where the land, water and labour constraints faced domestically are not present is seen as one viable strategic response. This offered investment opportunities to the private sector that governments have been willing to support. Some developing countries are making strenuous efforts to attract and facilitate foreign investment into their agricultural sectors. For them, foreign direct investment is seen as a
potentially important contributor to flling
the investment gap and stimulating domestic economic growth. However, how far these investments go towards meeting their real investments needs is
uncertain. The fnancial benefts to host
countries of asset transfers appear to be small, but foreign investments are seen as
potentially providing developmental benefts
through, for example, technology transfer,
employment creation, income generation and infrastructural developments. Whether
these potential developmental benefts will
actually be realized is a key concern.
the “land grab”
The much-publicised “land grab” involving the purchase or leasing of agricultural land in developing countries for food production is just one form of investment and one which arguably is least likely to
deliver signifcant developmental benefts
to the host country. Some countries are seeking foreign investments to exploit “surplus” land currently unused or underutilized. One reason land may not be used to its full potential is that the infrastructural investments needed to
bring it into production are so signifcant
as to be beyond the budgetary resources of the country. International investments might bring much needed infrastructural
investments from which all can beneft.
However, selling, leasing or providing concessional access to land raises the questions of how the land concerned was
figure 1: investor and target regions/countries in land investment for agriculture, 2006-2009
Source: UNCTAD
investor country target countrypreviously being utilized, by whom and on what tenurial basis. In many cases,
the situation is unclear due to ill-defned
property rights, with informal land rights based on tradition and local culture. While much land in sub-Saharan Africa may currently not be utilized to its full potential, apparently “surplus” land overall does not mean land is unused, unoccupied or unclaimed. Its exploitation under new investments involves reconciling different claims. Change of use and access may involve potentially negative effects on local food security and raise complex economic,
social and cultural issues. Such diffculties
at least demand consultation with those with traditional rights to land, and favour alternative mutual arrangements for investments.
alternatives to land aCquisition
It is also not clear that land acquisition is necessary or desirable even for investors. Acquisition of land does not necessarily provide immunity to sovereign risk and can provoke political, social and economic
conficts. Other forms of investment
such as contract farming and outgrower schemes can offer just as much security of supply. It is interesting to note that in other contexts, vertical coordination tends to be based much more on such non-equity arrangements than on the traditional acquisition of upstream or downstream stages. The development of East African horticultural production for export by European supermarket chains is a case in point. Such looser arrangements may be more conducive to the interests of the receiving country. However, even here there are likely to be questions as to the compatibility of the needs of investors with smallholder agriculture, and this in turn raises questions about poverty reduction potential. Nevertheless, joint
ventures might offer more spillover benefts
for the host country smallholders. Under contract farming or outgrower schemes,
smallholders can be offered inputs including credit, technical advice and a guaranteed
market, although they do sacrifce some
freedom of choice over crops to be grown. Mixed models are also possible with investments in a large-scale enterprise at the centre but also involving outgrowers under contracts to supplement production. What business model is most appropriate
will depend on the specifc circumstances
and the commodity concerned.
What are the developmental benefits of foreign investment?
The key issue is the extent to which
benefts from foreign investments spill
over into the domestic sector in a synergistic and catalytic relationship with existing smallholder production systems.
Benefts should arise from capital infows,
technology transfer leading to innovation and productivity increases, upgrading domestic production, quality improvement, employment creation, backward and forward linkages and multiplier effects through local sourcing of labour and other inputs and processing of outputs and possibly an increase in food supplies for the domestic market and for export. However,
these benefts will not fow if investment
results in the creation of an enclave of
advanced agriculture in a dualistic system with traditional smallholder agriculture, which smallholders cannot emulate. The historical evidence on the effects of foreign direct investment in agriculture suggests
that the claimed or intended benefts do not
always materialize and catalogue concerns over highly mechanized production technologies with limited employment
creation effects; dependence on imported
inputs and hence limited domestic multiplier
effects; adverse environmental impacts
of production practices such as chemical contamination, land degradation and
depletion of water resources; and limited
labour rights and poor working conditions. At the same time, however, there is also
evidence of longer-run benefts in terms of
improved technology, upgrading of local suppliers, better marketing systems and improved product quality and sanitary and phytosanitary standards, for example.Additional political, social and ethical concerns are raised where the receiving country is itself food insecure. While there is a presumption that investments will increase aggregate food supplies this does not imply that domestic food availability will increase, notably where food produced is exported to the investing country.

Extensive control of land by other countries can also raise questions of political
interference and infuence.
Code of ConduCt
Fears that local concerns are not emphasized in investment contracts and international investment agreements, that foreign investments in land acquisition do not always lead to local long-term
developmental benefts and that domestic
law is inadequate have prompted calls for an international code of conduct or guidelines to promote responsible investment in agriculture. In fact many countries lack the necessary legal or procedural mechanisms to protect local rights and take account of local interests, livelihoods and welfare.FAO, UNCTAD, IFAD and the World Bank are collaborating to develop a voluntary code of conduct highlighting the need for transparency, predictability, sustainability and stakeholder involvement and including domestic food security and rural development concerns. Such a code of conduct, based on detailed joint research concerning the nature, extent and impacts of foreign investment and best practices in law and policy, could provide a framework to which national regulations, international investment agreements, global corporate social responsibility initiatives and individual investment contracts might refer.
FAO is also developing voluntary guidelines on responsible governance of tenure of land and other natural resources in collaboration with other international organizations including UN-Habitat and the World Bank. The rationale for a code of conduct includes the considerations that: foreign investment has a great potential to help meet the investment needs of developing countries and provide
broader long-term developmental benefts;
international concern has been raised over the impacts on small farmers and food security of recent large-scale foreign land
acquisitions and leasing; there are fears that local concerns may not be suffciently
taken into account in investment contracts and international investment agreements, and that sometimes domestic law provides
inadequate safeguards; and international
guidelines might promote responsible
agriculture investments that would beneft
all stakeholders.
Questions for policy consideration
for developing Countries:
What policy and legal frameworks are
needed to maximize benefts, particularly
for local populations?
How can targeted inward investment be encouraged? How can a receptive domestic sector be created?
How can a positive investment climate be created?
How can consistency be achieved between encouraging inward investment
and existing food security and rural development strategies?
What safeguards are required regarding land-use rights and the involvement and compensation of stakeholders?
for investors:
Why focus on acquisition? What alternatives are there to equity investment?
How can outward investment be encouraged? What information and incentives are required?
How can private sector fnance be
mobilized?
What kind of national code of conduct is needed?
for the international Community:
How can investment programmes be devised to meet investment needs – matching capital to opportunities?
Is there a need for an international mechanism to cover covering investment agreements and dispute settlement?
How can global corporate social responsibility initiatives be brought into the process?

Food needs 'fundamental rethink'

Food needs 'fundamental rethink'

Food crops, agriculture and biodiversity cannot be separated from one another
A sustainable global food system in the 21st Century needs to be built on a series of "new fundamentals", according to a leading food expert.
Tim Lang warned that the current system, designed in the 1940s, was showing "structural failures", such as "astronomic" environmental costs.
The new approach needed to address key fundamentals like biodiversity, energy, water and urbanisation, he added.
Professor Lang is a member of the UK government's newly formed Food Council.
"Essentially, what we are dealing with at the moment is a food system that was laid down in the 1940s," he told BBC News.
"It followed on from the dust bowl in the US, the collapse of food production in Europe and starvation in Asia.
"At the time, there was clear evidence showing that there was a mismatch between producers and the need of consumers."
Professor Lang, from City University, London, added that during the post-war period, food scientists and policymakers also thought increasing production would reduce the cost of food, while improving people's diets and public health.

Raymond Blanc,
Chef and food campaigner
"But by the 1970s, evidence was beginning to emerge that the public health outcomes were not quite as expected," he explained.
"Secondly, there were a whole new set of problems associated with the environment."
Thirty years on and the world was now facing an even more complex situation, he added.
"The level of growth in food production per capita is dropping off, even dropping, and we have got huge problems ahead with an explosion in human population."
Fussy eaters
Professor Lang lists a series of "new fundamentals", which he outlined during a speech he made as the president-elect of charity Garden Organic, which will shape future food production, including:
  • Oil and energy: "We have an entirely oil-based food economy, and yet oil is running out. The impact of that on agriculture is one of the drivers of the volatility in the world food commodity markets."
  • Water scarcity: "One of the key things that I have been pushing is to get the UK government to start auditing food by water," Professor Lang said, adding that 50% of the UK's vegetables are imported, many from water-stressed nations.
  • Biodiversity: "Biodiversity must not just be protected, it must be replaced and enhanced; but that is going to require a very different way growing food and using the land."
  • Urbanisation: "Probably the most important thing within the social sphere. More people now live in towns than in the countryside. In which case, where do they get their food?"
Professor Lang said that in order to feed a projected nine billion people by 2050, policymakers and scientists face a fundamental challenge: how can food systems work with the planet and biodiversity, rather than raiding and pillaging it?
The UK's Environment Secretary, Hilary Benn, recently set up a Council of Food Policy Advisers in order to address the growing concern of food security and rising prices.

The 21st Century is going to have to produce a new diet for people, more sustainably, and in a way that feeds more people more equitably using less land
Professor Tim Lang
Mr Benn, speaking at the council's launch, warned: "Global food production will need to double just to meet demand.
"We have the knowledge and the technology to do this, as things stand, but the perfect storm of climate change, environmental degradation and water and oil scarcity, threatens our ability to succeed."
Professor Lang, who is a member of the council, offered a suggestion: "We are going to have to get biodiversity into gardens and fields, and then eat it.
"We have to do this rather than saying that biodiversity is what is on the edge of the field or just outside my garden."
Michelin-starred chef and long-time food campaigner Raymond Blanc agrees with Professor Lang, adding that there is a need for people, especially in the UK, to reconnect with their food.
He is heading a campaign called Dig for Your Dinner, which he hopes will help people reconnect with their food and how, where and when it is grown.
"Food culture is a whole series of steps," he told BBC News.
"Whatever amount of space you have in your backyard, it is possible to create a fantastic little garden that will allow you to reconnect with the real value of gardening, which is knowing how to grow food.
"And once you know how to grow food, it would be very nice to be able to cook it. If you are growing food, then it only makes sense that you know how to cook it as well.
"And cooking food will introduce you to the basic knowledge of nutrition. So you can see how this can slowly reintroduce food back into our culture."
Waste not...
Mr Blanc warned that food prices were likely to continue to rise in the future, which was likely to prompt more people to start growing their own food.

Sustainable food helps protect rare breeds and varieties
Raymond Blanc on good food
He was also hopeful that the food sector would become less wasteful.
"We all know that waste is everywhere; it is immoral what is happening in the world of food.
"In Europe, 30% of the food grown did not appear on the shelves of the retailers because it was a funny shape or odd colour.
"At least the amendment to European rules means that we can now have some odd-shaped carrots on our shelves. This is fantastic news, but why was it not done before?"
He suggested that the problem was down to people choosing food based on sight alone, not smell and touch.
"The way that seeds are selected is about immunity to any known disease; they have also got to grow big and fast, and have a fantastic shelf life.
"Never mind taste, texture or nutrition, it is all about how it looks.
"The British consumer today has got to understand that when they make a choice, let's say an apple - either Chinese, French or English one - they are making a political choice, a socio-economic choice, as well as an environmental one.
"They are making a statement about what sort of society and farming they are supporting."
Growing appetite
The latest estimates from the UN Food and Agriculture Organization (FAO) show that another 40 million people have been pushed into hunger in 2008 as a result of higher food prices.
This brings the overall number of undernourished people in the world to 963 million, compared to 923 million in 2007.
The FAO warned that the ongoing financial and economic crisis could tip even more people into hunger and poverty.
"World food prices have dropped since early 2008, but lower prices have not ended the food crisis in many poor countries," said FAO assistant director-general Hafez Ghanem at the launch of the agency's State of Food Insecurity in the World 2008 report.
"The structural problems of hunger, like the lack of access to land, credit and employment, combined with high food prices remain a dire reality," he added.
Professor Lang outlined the challenges facing the global food supply system: "The 21st Century is going to have to produce a new diet for people, more sustainably, and in a way that feeds more people more equitably using less land."

Food figures need a pinch of salt

VIEWPOINT
Isobel Tomlinson
The idea that the world needs to double its food production by 2050 in order to feed a growing population is wrong, says Isobel Tomlinson from the Soil Association. In this week's Green Room, she says the misuse of data could be used to allow even greater intensification of the global agricultural industry.
Vegetables (Getty Images)
It is important that scientific research is now done to show how a better future is possible
In the last couple of years, scientists, politicians and agricultural industry representatives around the globe have been using two statistics: the need to increase global food production by 50% by 2030, and for food production to double by 2050 to meet future demand.
These figures have come to play a significant role in framing current international policy debates about the future direction of global agriculture.
These apparently scientific statistics have been dominating the policy and media discourse about food and farming, leading almost everyone to assume we need vast increases in agricultural production to feed a population of nine billion people by the middle of this century.
While ensuring an equitable and sufficient future food supply is of critical importance, many commentators are using this to justify the need for more intensive agricultural practices and, in particular, the need for further expansion of GM crops.
Cooking the books
When the Soil Association, in its report Telling Porkies, looked into the reported sources for these figures, none of the sources actually stated that global food production needs to increase by 50% by 2030, or to double by 2050.
Spider's web covered in frost
The food web is complex and tough to break down into simple soundbites
What the reports on which the claims are based do say is that certain sectors, in certain parts of the world, may have to increase food production by significant amounts.
For example, for cereals, there is a projected increase of one billion tonnes annually beyond the two billion tonnes produced in 2005.
For meat, in developing countries only (except China), the reports say that some of the growth potential (for increased per capita meat consumption) will materialise as effective demand, and their per capita consumption could double by 2050.
So this is a projected doubling of meat consumption in some developing countries - not a doubling of global food production.
Indeed, recent calculations show that the key source for the "doubling" claim - a 2006 report from the UN Food and Agriculture Organization (FAO) - implies that global food production for 2006-2050 would need to increase by around 70%, not 100%; a difference that is equivalent to the entire food production of the continent of America.
But while a re-evaluation of the veracity of the claim that food production needs to double by 2050 is to be welcomed, simply switching to the figure of 70% does not solve the problem.
Food for thought
The statistic of a 70% increase is still predicted on the same "business as usual" model as the "doubling" figure and that is problematic for several reasons:
Rice cultivation
Some region will have to produce considerably more food
Food push urged to avoid hunger
First of all, the projections reflect a continuing pattern of structural change in the diets of people in developing countries with a rapid increase in livestock products (meat, milk, eggs) as a source of food calories.
However, the continuation of dietary transition in developing countries, as assumed by the modelling work, is likely to cause worsening health problems as such diets are a leading cause of non-communicable diseases including cardiovascular disease, some cancers and Type 2 diabetes.
Secondly, the data used to measure food security focuses attention on the level of agricultural production without considering access to food, distribution, and affordability which are all important in ensuring that people do not go hungry.
Thirdly, the projections assume that the developing world continues to import growing quantities of staple food stuffs when, in fact, increasing local production of staple foods is vital in ensuring food security.
Finally, according to these scientists, meeting these projected food demand targets will not solve food insecurity anyway. Indeed it is predicted that there will still be 290 million under-nourished people worldwide in 2050.
The assumptions and projections in this modelling reflect the authors' vision of the "most likely future" but not necessarily the most desirable one.
At the Soil Association, we now want to have an honest debate about how we can feed the world in 2050 in a way that doesn't lead to the further increases in obesity and diet related diseases, ensures that the global environment is protected, and that puts an end to hunger and starvation.
The misuse of the doubling statistic, based as it supposedly is on just one particular forecast of future demand for food, has prevented alternative visions of food and farming in 2050, which do not rely on the further intensification of farming and use of GM technologies, from being taken seriously in food security policy circles.
It is important that scientific research is now done to show how a better future is possible.
One recent scientific study has examined how we can feed and fuel the world sustainably, fairly and humanely. It explored the feasibility of feeding nine billion people in 2050 under different diet scenarios and agricultural systems.
The study showed that for a Western high-meat-diet to be "probably feasible" would require a combination of massive land use change, intensive livestock production and intensive use of arable land.
This would have negative impacts for animal welfare and lead to further destruction of natural habitats like rainforests.
However, the study also provides evidence "that organic agriculture can probably feed the world population of 9.2 billion in 2050, if relatively modest diets are adopted, where a low level of inequality in food distribution is required to avoid malnutrition".

Do you agree with Isobel Tomlinson? Is it wrong to suggest that the world needs to double its food production by 2050? Will it lead to the intensification of the globe's agricultural industry? Or do we just have to accept that there is never going to be universal food security, and develop ways to help as many people has possible with the resources we have?
We have to plan infinite things to satisfy one unplanned thing i.e. Growth of human population. Either, there are 'without power' powerful leaders, who can not speak on the most basic issue or there are 'genuine' powerful leaders who are wasting their power in neutralizing the frivolous issues raised by their opposition and media. Most of the places, we are handling the results of the problem. Why do not we hit at the source? Why do not we raise the most basic issue? Why not this issue is getting importance in my own country? Not a single political leader is realizing the abnormal growth of human population.

The FAO was very quick to adjust their projection to a 70 per cent increase after the initial quote got out and most commentators adjusted accordingly long ago, so it's a bit disingenuous to extend the critique of an estimate that has already been refined and will continue to be. To quibble about how big an increase will be required diminishes the matter at stake, but of course that's the objective of the article. To sum it up: FAO has made a credible forecast; we'll never know for certain until it's all over and we certainly can't wait till then to do something about it. It's our food supply after all. Whether we need to increase production by 50 or 70 or 100 percent is not the point. What's really important is that the population of Europe and the world will continue to increase and food supplies will have to be boosted in the face of critical challenges (climate change, availability of water, environmental protection, biodiversity, distribution, affordability etc). The big question is whether we are going to increase the agricultural land base (and cut down more forests to grow food) or become more productive in a sustainable way on existing farmland. Deforestation is agriculture's single biggest contribution to greenhouse gas emissions and the destruction of biodiversity. It's a fact that organic methods require more land to grow the same amount of food (up to three times) and the crops are by far more susceptible to the pests and disease that have plagued food production throughout human history when the whole of agriculture was "organic". Organic is fine in some circumstances and not in others, but it's not the answer to the food supply challenge, which is very likely the biggest we face. It would be very helpful if every stakeholder in the agricultural and food policy community accepted this cold, hard fact as soon as possible. It's not a matter of the right or wrong ideology of farming. It's about resisting the age-old human solution to hunger which is to expand farmland. It's about efficiency and productivity, quality and affordability, and the full and rational application of science and technology to sustaining the our food supply sustainably.

One would hope that long before 2050 or even 2030, we in the so-called Developed World will have realised that we are eating far too much. I was born in 1969, and everyone I grew up with was slim during the 1970s and 80s. Now 1 in 3 are overweight or obese. And guess what, our calorie intake is much higher. The answer is to drop back down to a more reasonable level of personal consumption - which will also overcome many of the diseases of excess such as heart disease and tumours. Then make projections on what is likely. The fact is that, much as advertisers would like us to, we don't need to all eat a burger and chips and chocolate diet.

You can't believe anything when it comes to food. We're all on a healthy eating kick now. Due to the large number of centenarians in the Mediterranean countries, we've been coerced and bullied into changing our diet. Now we find that most of these 104 year olds have been dead for decades while their families continued to claim their pensions.

Food equality is the key issue. Global production of food in vegetable form is twice what is needed to feed the world's population - 4,200 calories per person per day. But it's not so unequally distributed, and much is wasted. E.g. about 40% of global food production is fed to animals not people, and the meat produced contains less than a third of the calories of the animal feed. So I think we urgently need an open debate on alternatives to "business as usual". We don't need high-tech, but we do need high-ethic.

Nobody should take any prediction that far into the future seriously. On the other hand, the Soil Association wants to move the world backwards in agriculture, not forwards. They and the rest of the anti-technology anti-GM comfortable middle class (i.e. rich) are part of the problem, not part of the solution.
W Boucher, Cambridge, UK
It's certainly a question of how food is produced, rather than just focusing on how much is produced. As mentioned recently on BBC News - looking at bees shows a clear indication of increasing broad scale mono-culture is unhealthy, and ultimately unsustainable. Here in Australia, there are many examples of farmers applying ecological perspectives in land management, utilising natural services and producing greater yields more "naturally".I also agree that much of the western diet and food management creates both needless health problems and excessive waste. Isobel is correct in saying that we need to "have an honest debate about how we can feed the world in 2050 in a way that doesn't lead to the further increases in obesity and diet related diseases, ensures that the global environment is protected, and that puts an end to hunger and starvation." There is great potential for improvement which should lead to greater efficiency (and ultimately reduction in cost of food, plus health related issues). However, the problem is as much social - where it's cheaper to grow (often with transport being cheap, this leads to what seems odd choices), what is culturally desired etc. Eventually you'll find that you're no longer looking at food production, but how we choose to live. Asking questions here will lead to even greater resistance. But again - real debate and discussion, based on solid evidence, is the only way forward. I also feel it premature to rule out GM as playing any role - not that I'm advocating GM over all else, but I do feel that it must play an important role in some way.

I think the most important thing is to tell some countries and people stopping produce more human beings, slowing down the depletion our limited resources, recycling everthing as much as we can. Don't chase the luxury life, have a comfortable and happy life.

I have mixed feelings,it is very essential to explore how globalization, broadly conceived to include international human rights norms, humanitarianism, and alternative trade, might influence peaceful and food secure outlooks and outcomes. It should review studies on the relationships between (1) conflict and food insecurity, (2) conflict and globalization, and (3) globalization and food insecurity. Next, it would be analyzed country level, historical contexts where export crops, such as coffee and cotton, have been implicated in triggering and perpetuating conflict. It suggest that it is not export cropping per Se, but production and trade structures and food and financial policy contexts that determine peaceful or belligerent outcomes. Export cropping appears to contribute to conflict when fluctuating prices destabilize household and national incomes and when revenues fund hostilities.

animal feed has been contaminated by dioxins

German dioxin contamination eggs exported to UK

German eggs Contaminated animal feed was sent to poultry and pig farms in Germany

Related stories

Eggs from German farms where animal feed has been contaminated by dioxins have found their way into processed products destined for British food.

The EU executive said 14 tonnes of the liquid food had been exported to the UK but stressed there was a very low risk to human health.

The UK's Food Standards Agency agreed, saying the eggs would have become diluted with other products.

The FSA said it was trying to trace the shipment in the UK.

It said that following the distribution of affected eggs to the Netherlands they were mixed with non-contaminated eggs to make pasteurised liquid egg.

This product has been distributed to the UK.

'Product for consumption'

The FSA said in a statement: "The mixing of the eggs will have diluted the levels of dioxins and they are not thought to be a risk to health.

"The FSA is currently liaising with the industry and will provide further updates as information becomes available."

Dioxins

  • Dioxins are a group of chemicals commonly formed as by-products of industrial combustion and chemical processes, such as manufacturing of chemicals, pesticides, steel and paints, pulp and paper bleaching, exhaust emissions and incineration
  • The main source of dioxin contamination of food for human consumption is contaminated animal feed
  • Dioxins are absorbed by fatty tissue of cattle, poultry, pork and seafood. Foods high in animal fat, such as milk, meat, fish and eggs (and foods produced with them) are the main source of dioxins although all foods contains some
  • Dioxins are found throughout the industrialised world, in air, water and soil, as well as in food
  • Dioxins can cause problems for people if they are absorbed at high levels for long periods
  • They have been shown in lab tests to cause a wide range of effects in certain animals, such as cancer and damage to the immune and reproductive systems, including low sperm count and learning difficulties

The alert began when it was discovered thousands of tonnes of animal feed contaminated by highly toxic dioxins had been sent to more than 1,000 poultry and pig farms in Germany.

Eggs from those farms were sent to the Netherlands for processing and then on to the UK where they are likely to have been used in the production of a variety of foodstuffs including mayonnaise and pastries.

European Commission health spokesman Frederic Vincent told a news conference how the problem had now reached the UK.

"Those eggs were then processed and then exported to the United Kingdom... as a 14-tonne consignment of pasteurised product for consumption," he said.

"Whether it went into mayonnaise, pastries, I don't know. So we will probably take a look at this with the UK authorities and see what was done with these eggs."

Farms closed

The problem has been traced to oils intended for bio-fuel becoming mixed with oil destined for animal feed.

The dioxin was discovered in late December but the extent of the problem was only revealed earlier this week when German officials said 3,000 tonnes of feed had been affected.

Germany has closed more than 4,700 farms, mostly in the Lower Saxony region in north-west Germany.

German officials will brief their EU counterparts next week and the incident could lead to new rules on animal feed.

Dioxins are toxins formed by industrial processes and waste burning.

They have been shown to contribute to higher cancer rates and to affect pregnant women.

rising food prices re-emerging as a threat to global growth and stability


G20 Must Act To Stabilize Food Prices. “With, the G20 industrial and developing nations should prioritize the provision of food for the poor, World Bank President Robert Zoellick says. In an opinion piece in Thursday's FT, Zoellick sets out nine action points to ensure the poor have access to food. …
French President Nicholas Sarkozy has identified food price volatility as a priority for his country as it takes the presidency of the G20 in 2011. …Zoellick called for more efforts to understand the relationship between international prices and local prices in poor countries. And he said food aid should be exempted from export bans. …” [Dow Jones/Factiva]
Reuters reports that “… ‘The answer to food price volatility is not to prosecute or block markets, but to use them better,’ Zoellick wrote in an opinion piece in Thursday's FT urging G20 leaders to put access to food at the top of its agenda. ‘By empowering the poor the G20 can take practical steps towards ensuring the availability of nutritious food,’ he wrote. …
He also called for an international code of conduct to exempt humanitarian food aid from export bans. …Other steps include improving supply transparency and long-weather forecasting, creating small humanitarian reserves in disaster-prone regions and providing alternatives to export bans and price fixing. Risk management products, such as weather insurance or a hedge on energy prices to keep transport and input costs low, should also be considered, he said.” [Reuters/Factiva]
The opinion by Zoellick published in the FT also writes that “…Increase public access to information on the quality and quantity of grain stocks. Better information reassures markets and helps calm panic-induced price spikes. Multilateral institutions could help identify ways to improve transparency.
Improve long-range weather forecasting and monitoring, especially in Africa. Accurate long-range weather forecasting is taken for granted by farmers and purchasers in the developed world; in poor countries where yields depend on rainfall, poor crop projections amplify price swings. Better weather forecasting would enable people to plan ahead, and help anticipate needs for assistance. The World Meteorological Organisation and the World Bank are already helping, but more is needed. …
Ensure effective social safety nets. It is vital that we protect the most vulnerable populations, such as pregnant and lactating women and children under two. We need to connect agriculture and nutrition, and help countries target those most in need at reasonable cost.
Give countries access to fast-disbursing support as an alternative to export bans or price fixing. To help countries avoid policies that harm their own farmers and neighbors, we need to provide reliable, fast alternatives customized to local needs. The World Bank has created a crisis response window under the International Development Association (IDA), its $49bn fund for the poorest countries, and launched a rapid-response Food Security Fund, but we could also explore credit lines or loans with repayment suspension and extension during price shocks. …
The answer to food price volatility is not to prosecute or block markets, but to use them better. By empowering the poor, the G20 can take practical steps towards ensuring the availability of nutritious food. Mr Sarkozy has shown leadership in putting this issue on the G20 agenda; the G20 must now act to put food first.” [The Financial Times/Factiva]
Food Prices Surge, Lifting Unrest Fears. “A prominent indicator of international food prices hit a record high in December, sounding a warning about looming threats to the world's poor and to global growth. The UN Food and Agriculture Organization's monthly food price index rose for the sixth consecutive month to 214.7, topping the previous peak, 213.5, reached in June 2008.
The index doesn't measure domestic retail prices, which can be affected by a wide range of factors, including government subsidies. Instead, the index tracks export prices and can still serve as a barometer of what consumers may pay. The prior record was set months after violent food riots struck several nations, an experience that is heightening concerns about potential consequences from the current rise. …” [The Wall Street Journal/Factiva]
FT notes that “…The warning from the UN body comes as inflation is becoming an increasing economic and political challenge in developing countries, including China and India, and is starting to emerge as a potential problem even in developed countries, including the UK and the eurozone.
Abdolreza Abbassian, senior economist at the FAO in Rome, said the spike was ‘alarming’, but added the situation was not yet a crisis similar to 2007-08, when food riots broke out in more than 30 poor countries, from Bangladesh to Haiti. …Abbassian painted a sombre outlook, warning that agricultural commodities prices were likely to rise further. ‘It will be foolish to assume this is the peak,’ he said. …” [The Financial Times/Factiva]
Dow Jones reports that Abbassian “… said poorer countries will at some point have to tap the international markets for foodstuffs. ‘That is the worrisome development...We consider the [current] prices quite punitive for the poorer countries.’ Abbassian said there is more likelihood that prices will rise in 2011 than fall. Any potential price correction is unlikely until the middle of the summer when the next harvests are due to begin.” [Dow Jones/Factiva]

"We need to double food production,

Enviropig™

The Enviropig™ is a genetically enhanced line of Yorkshire pigs with the capability of digesting plant phosphorus more efficiently than conventional Yorkshire pigs. These pigs produce the enzyme phytase in the salivary glands that is secreted in the saliva. When cereal grains are consumed, the phytase mixes with the feed as the pig chews. Once the food is swallowed, the phytase enzyme is active in the acidic environment of the stomach, degrading indigestible phytate in the feed that accounts for 50 to 75% of the grain phosphorus.

Phytase produced in the salivary glands and secreted in the saliva increases the digestion of phosphorus contained in feed grains

Figure 1. Phytase produced in the salivary glands and secreted in the saliva increases the digestion of phosphorus contained in feed grains.

Since the Enviropig™ is able to digest cereal grain phosphorus there is no need to supplement the diet with either mineral phosphate or commercially produced phytase, and there is less phosphorus in the manure. When the phosphorus depleted manure is spread on land in areas of intense swine production there is less potential of phosphorus to leach into freshwater ponds, streams and rivers. Because phosphorus is the major nutrient enabling algal growth that is the leading cause of fish kills resulting from anoxic conditions, and reduced water quality, the low phosphorus manure from Enviropigs has a reduced environmental impact in areas where soil phosphorus exceeds desirable levels. Therefore the enviropig biotechnology has two beneficial attributes, it reduces feed cost and reduces the potential of water pollution. Furthermore, the technology is simple, if you know how to raise pigs, you know how to raise EnviropigsThe BBC's Jeremy Cooke has had rare access to some genetically modified Enviropigs in Canada

In a small complex of nondescript barns set in the flat, snow-covered fields of Ontario is a scientific project which, some argue, represents the new frontier of a technology that could benefit millions of people around the world.

For others what is happening here is weird, dangerous science.

The pigs they are breeding could be among the first genetically modified farm animal to be approved for human consumption.

The huge controversy over the introduction of genetically modified crops is well documented, but this seems to take that debate a step further, and into even more troubled waters.

The project here is called Enviropig. The animals inside the clean, warm barns look like normal pigs and behave like normal pigs, but they are living, breathing wonders of modern science.

Each one contains genes from mice and E.coli bacteria, which have been inserted into their DNA with absolute precision.

Those genes make a small but important difference to the way these pigs process their food.

Ordinarily, pigs cannot easily digest chemicals called phosphates. That means that the stuff that comes out of the back end can be toxic and damaging to the environment. The phosphates are easily washed into waterways, where they can produce a hugely fertile environment for plants. But the plants grow so rapidly that they choke the stream or river and cause huge damage to the ecosystem.

THE ENVIROPIG

Between 50% and 75% of the phosphorus present in cereal grains including corn, soybeans, barley and wheat is present in an indigestible compound called phytate that passes through the pig's digestive tract. The Enviropig is a genetically enhanced line of Yorkshire pigs with the capability of digesting plant phosphorus more efficiently than conventional Yorkshire pigs.

The genetic modification enables these pigs to digest phosphates, which means they are less polluting and cheaper to feed.

Controversial

Professor Rich Moccia of the University of Guelph is proud of what has been achieved.

"It's the forefront of discovery in the scientific community. It's one of only two animals right now using this kind of technology. It really is mind-boggling when you think of it."

But it is controversial. To those who have campaigned so long and hard against the introduction of Genetically Modified (GM) crops, the notion of genetically engineered animals, such as Enviropig and fast-growing GM salmon, is a new front in a long war.

In Toronto, the Big Carrot supermarket is among the few GM-free outposts in North America. They have been fighting for years to hold back the tidal wave of genetically modified produce.

For anti-GM campaigner Lucy Sharratt, the very notion of transgenic animals is a nightmare.

Lucy Sharratt, of the Canadian Biotechnology Action Network, discusses her concerns

"This is an absolutely critical time when North America is at the very centre of the global conflict over genetically engineered animals - to break open a whole new area of application of this technology, which we had never imagined would be possible.

"I am very worried and I think people around the world should be worried about what's happening in North America," she says.

Clearly the debate remains deeply polarised. But there are also some indications that the debate may be slowly shifting.

Dr Mart Gross, of the University of Toronto, used to oppose the idea of GM crops and animals. Now he has changed his mind. Feeding the human population, he says, must come first, and GM animals and plants may help.

"We need to double food production," he says. "We currently have a global population of almost seven billion and we are looking at nine, 10 or 11 billion by 2050.

"Where is that food going to come from? We have to produce more from less."

The inventors of Enviropig know that it is by no means certain that government regulators will ever approve GM animals for human consumption.

But the massive challenge of feeding a rocketing global population, and doing it in a sustainable way, could shift the debate and ultimately dictate whether Enviropigs end up on our dinner plates.

Cloned cattle food safe to eat, say scientists

The BBC's Pallab Ghosh looks at how cloned meat reaches the dinner table

Meat and milk from cloned cattle and their offspring are safe to consume, independent scientists have said.

The Advisory Committee on Novel Foods and Processes said it believed the food was unlikely to present any risk.

The Food Standards Agency will discuss the conclusions in December before providing further advice to ministers.

Questions raised by reports over the summer that meat from cloned animals' offspring was sold to consumers "remain unanswered", the Soil Association says.

However, the committee's scientists said there was no substantial difference between meat and milk from cloned animals and produce from conventional livestock, in line with a number of other scientific assessments.

Three cases had emerged of meat linked to a cloned cow being sold in the UK, according to the Food Standards Agency (FSA).

Two involved Highlands farm bulls grown from embryos of a cow cloned in the US, while the third involved meat from a male calf being sent to a London butcher's shop.

Disadvantage claim

The FSA said the calf was the offspring of one of eight animals born in the UK from embryos produced by the US cloned cow.

FSA chief scientist Andrew Wadge said: "The Advisory Committee on Novel Foods and Processes has confirmed that meat and milk from cloned cattle and their offspring shows no substantial difference to conventionally produced meat and milk, and therefore is unlikely to present a food safety risk."

Not only does cloning have a negative impact on animal welfare, we also have no long-term evidence for the impacts on health”

In the US, South America and Asia, farmers can breed from cloned cows, sheep and pigs in order to increase milk and meat production.

However, farmers in Europe who want to introduce the products of cloned animals into the food chain require specific authorisation because they are considered "novel foods".

BBC science correspondent Pallab Ghosh says this is in effect a ban. Breaches of the Novel Food Regulations can attract a fine of up to £5,000.

Some European farmers believe they are being put at a disadvantage by being denied the option of using the technology, our correspondent adds.

Critics say there are strong ethical and animal welfare reasons to ban its use in European agriculture.

"There are many unanswered questions on the issue of cloning animals - both ethical and practical - and insufficient regulation," said a Soil Association spokeswoman.

"Not only does cloning have a negative impact on animal welfare, we also have no long-term evidence for the impacts on health."

The European Commission proposes to ban meat and milk from clones and their offspring. The FSA board will discuss this at its December meeting, with the outcome influencing Britain's negotiations on the issue in Europe.

A spokesman said the board had asked for clarity from Europe but that any change in position was unlikely to come in the short term.

"It is for individual member states to interpret European law but, obviously, we differ from the commission on this," he said.

Why garlic is good for the heart

Why garlic is good for the heart
Garlic
The smell may be a healthy sign
Researchers have cracked the mystery of why eating garlic can help keep the heart healthy.

The key is allicin, which is broken down into the foul-smelling sulphur compounds which taint breath.

These compounds react with red blood cells and produce hydrogen sulphide which relaxes the blood vessels, and keeps blood flowing easily.

The University of Alabama at Birmingham research appears in Proceedings of the National Academy of Sciences.

Our results suggest garlic in the diet is a very good thing
Dr David Kraus
University of Alabama

However, UK experts warned taking garlic supplements could lead to side effects.

Hydrogen sulphide generates a smell of rotten eggs and is used to make stink bombs.

But at low concentrations it plays a vital role in helping cells to communicate with each other.

And within the blood vessels it stimulates the cells that form the lining to relax, causing the vessels to dilate.

This, in turn, reduces blood pressure, allowing the blood to carry more oxygen to essential organs, and reducing pressure on the heart.

The Alabama team bathed rat blood vessels in a bath containing juice from crushed garlic.

Striking results

This produced striking results - with tension within the vessels reduced by 72%.

The researchers also found that red blood cells exposed to minute amounts of juice extracted from supermarket garlic immediately began emitting hydrogen sulphide.

Further experiments showed that the chemical reaction took place mainly on the surface of the blood cells.

The researchers suggest that hydrogen sulphide production in red blood cells could be used to standardise dietary garlic supplements.

Lead researcher Dr David Kraus said: "Our results suggest garlic in the diet is a very good thing.

"Certainly in areas where garlic consumption is high, such as the Mediterranean and the Far East, there is a low incidence of cardiovascular disease."

Judy O'Sullivan, a cardiac nurse at the British Heart Foundation, said: "This interesting study suggests that garlic may provide some heart health benefits.

"However, there remains insufficient evidence to support the notion of eating garlic as medicine in order to reduce the risk of developing coronary heart disease.

"Having garlic as part of a varied diet is a matter of personal choice.

"It is important to note that large amounts in supplement form may interact with blood thinning drugs and could increase the risk of bleeding.
