The impact of the European Novel Food Regulation on trade and food innovation based on traditional plant foods from developing countries

Received 29 January 2009; revised 10 August 2009; accepted 15 August 2009. Available online 9 September 2009.
The stringent food safety assessment for novel foods required by the European Union’s Novel Food Regulation (NFR) places a high burden of proof on those bringing traditional food products to the EU market not consumed in the EU prior 1997. The regulation has emerged as a non-tariff trade barrier for heritage foods from developing countries that are viewed as “exotic” from the EU perspective. We show how the regulation has discouraged investment in supply chains and market development, and how this negatively affects income generation and rural poverty alleviation in developing countries. Focusing on plant-derived foods, this paper proposes to recognize traditional exotic foods in current EU law as a food category sui generis with food safety evidence requirements being proportionate to the risks they may pose. We argue that development activities promoting export food chains must increasingly accommodate legitimate food safety concerns about neglected food species in project design and seek to generate data to enhance regulatory acceptance in target markets.

USDA Highlights Specialty Crop Research and Extension
Source: U.S. Department of Agriculture
Posted on: 19th November 2009
Agriculture Secretary Tom Vilsack today announced that USDA has awarded more than $46 million through the Specialty Crop Research Initiative (SCRI) to solve critical specialty crop agriculture issues, address priorities and solve problems through multifunctional research and extension.
“Specialty crops are an important part of American agriculture, valued at nearly $50 billion every year,” Vilsack said. “This significant investment into research, education and extension will enable specialty crop producers to improve their products and increase their profitability.”
The Specialty Crop Research Initiative was established by the 2008 Farm Bill to support the specialty crop industry by developing and disseminating science-based tools to address the needs of specific crops in five focus areas: 1) improve crop characteristics through plant breeding, genetics and genomics; 2) address threats from pests and diseases; 3) improve production efficiency, productivity and profitability; 4) develop new innovations and technologies and 5) develop methods to improve food safety. Each of the focus areas received at least 10 percent of the available funds. The majority of the funded projects address two or more focus areas.
The projects funded in 2009 address research and extension needs for crops that span the entire spectrum of specialty crops production, from studying invasive mealy bug pests in west coast vineyards to developing biodegradable mulches for specialty crops produced under protective covers. Major projects were also funded to protect important specialty crops from invasive pests and to develop improved varieties.
Although 20 institutions will manage the research/extension grant funds from this program, each award includes an average of 8 principal investigators from three other states who will work together in a multi-disciplinary approach to solve problems. All of the awards required 100 percent matching funds from non-federal sources which will double the impact of the award dollars.

agroBIODIVERSITY A NEW SCIENCE AGENDA FOR BIODIVERSITY IN SUPPORT OF SUSTAINABLE AGROECOSYSTEMS
From : http://www.agrobiodiversity-diversitas.org
Biodiversity loss in agricultural landscapes affects not just the production of food, fuel, and fiber, but also a range of ecological services supporting clean water supplies, habitats for wild species, and human health. The world’s population of 6.3 billion people is projected to grow to 9 billion by 2050. To meet the increased demand for food, more land will be converted to agriculture, and agricultural intensification will increase, thereby increasing the pressure on biodiversity in natural ecosystems. Given the expected growth in human population and predicted environmental change, research is needed predicted effects on environmental change, research is needed that shows how the utilization and conservation of biodiversity can provide ecosystem services to satisfy both current
and future needs. The goal of the agroBIODIVERSITY science plan and implementation strategy is to establish the scientific basis needed to address the trade-offs between food production, biodiversity conservation, ecosystem services,
and human well being in agricultural landscapes. Three key research foci of the agroBIODIVERSITY Science Plan integrate the biological and social sciences:
(1) To assess biodiversity in agricultural landscapes and the anthropogenic drivers of biodiversity change; (2) To identify the goods and services provided by agrobiodiversity at various levels of biological organization, e.g., genes, species, communities, ecosystems, and landscapes; (3) To evaluate the socioeconomic options for the sustainable use of biodiversity in agricultural landscapes. Innovative biodiversity-rich farming systems can potentially be high-yielding and sustainable, and thus support persistence of wild species by limiting the adverse effects
of agriculture on habitats. Adoption of farming practices that utilize and conserve biodiversity may ultimately improve environmental quality and limit agricultural
expansion. Conservation of biodiversity and human knowledge from traditional agroecosystems is an urgent priority, to support human societies that rely on its cultural services, and for its potential for solving agricultural problems, now and in the future. Implementation of the agroBIODIVERSITY Science Plan will involve collaboration between geneticists, ecologists, anthropologists, and economists, to cross ecosystem boundaries to understand the environmental and social drivers of biodiversity change, ecosystem services provided by biodiversity in agricultural landscapes, and how to use this information for policy-relevant strategies to meet
human needs. Innovative methods for data handling and analysis across disciplines are required, as are protocols for integrating formal and informal knowledge. Workshops, publications, and projects by international networks of scientists will result in various scientific products that will increase useful knowledge for a variety of stakeholder groups.
Examples of activities will include:
Assemble and synthesize current knowledge,
Develop new approaches, methods, and models for
assessing biodiversity in agricultural landscapes, and for
determining issues that affect the sustainable use and
conservation of biodiversity in agriculture
Establish international networks that promote research
and capacity building among researchers involved in biodiversity
science in agricultural landscapes
Conduct research linking the biophysical and socioeconomic
sciences to develop new knowledge that will support
decisions for biodiversity utilization and conservation
in agricultural landscapes
Produce synthetic outcomes of research activities and
promote the development of policy-relevant materials related
to sustainable use of biodiversity
Lead outreach efforts to show the successful outcomes
of approaches that link biophysical and socioeconomic
sciences for sustainable use of biodiversity in

Managing genetic variation in tropical trees: linking knowledge with action in agroforestry ecosystems for improved conservation and enhanced livelihoods
Ian K. Dawson • Ard Lengkeek • John C. Weber •Ramni Jamnadass
From : CropWildRelativesGroup@yahoogroups.com
Tree species in agroforestry ecosystems contribute to the livelihoods of rural
communities and play an important role in the conservation of biodiversity. Unless agroforestry landscapes are productive, however, farmers will not maintain or enhance the range and quality of tree species in them, and both income opportunities and biodiversity will be lost.
Productivity depends on both tree species diversity and genetic (intra-speciWc) variation, but research on the latter has until recently not received the recognition it deserves. Worse, when knowledge on tree genetic variation in agroforestry systems has become available, it has not generally been linked in any systematic way with management, indicating a disjunction between research and Weld-level practice. In this essay, we attempt to bridge this gap by considering three questions: why is genetic diversity important in tree species? What is our current state of knowledge about intra-speciWc variation in trees in agroforestry systems? And, Wnally, what practical interventions are possible to support the conservation of this diversity in agricultural landscapes, while enhancing farmers’ livelihoods? A wide genetic base in agroforestry trees is essential to prevent inbreeding depression and allow adaptation to changing environmental conditions and to altering markets for tree products. Recent evidence shows, however, that many species are subject to poor germplasm collection practice, occur at low densities in farmland, and are found in highly aggregated distributions, all of which observations raise concerns about productivity and sustainability. A range of germplasmaccess
based interventions is necessary to improve current management, including the
enhancement of community seed- and seedling-exchange networks, and the development of locally based tree domestication activities. Equally necessary, but more diYcult to address, isthe development of markets that support genetic diversity in tropical tree species; we discuss approaches by which this may be undertaken.

Clean technology as a public good
From : SciDev Net
Clean technology to meet poor communities' needs must lie at the heart of any sustainable strategy to combat climate change.
A widely-held myth among climate change activists is that discussing the need for improved technology to mitigate or adapt to climate change detracts from political debates on who is to blame for unsustainable lifestyles — and who should pay for their consequences.
Like many myths, this one contains an element of truth. Purely technological responses to climate change have, on occasion, been proposed to avoid difficult political choices.
The United States' approach to the Asia-Pacific Partnership on Clean Development and Climate four years ago (see Asia-Pacific climate pact launched) is a notable example.
But the myth is also a dangerous one. It ignores the fact that any effort to combat climate change will only succeed if it can draw on technologies that do not, in the long run, add to the global burden of carbon emissions (see Climate change's technology transfer challenge).
The first political challenge — due to emerge at next month's UN Climate Change Convention (COP-15) in Copenhagen — is to ensure sufficient funding to urgently develop clean technologies.
The second is to guarantee that equal effort is devoted to ensuring that such technologies do not hinder the world's poorest communities from improving their standards of living through economic development.
The good news is that the first of these challenges seems to have been taken seriously. Climate negotiators have long realised that developing clean technology and transferring it to developing nations are fundamentals of any global strategy to combat climate change.
But some assessments of the technological challenge ahead are sobering. A European Commission report emerging from pre-Copenhagen discussions, for example, estimates that the developing world will need up to US$150 billion over the next decade to cope with climate change.
One of the more ambitious, yet convincing solutions on the table next month is the G-77 plus China's idea of a UN-operated multilateral climate technology fund (MCTF).
Using a multilateral system to identify technological needs and priorities avoids the type of political trading that too frequently accompanies bilateral funding programmes, where donor's interests can be as influential as those of the recipient.
A free resource
But neither more money alone, nor an international mechanism to collect and distribute such funding, will be sufficient.
It is equally important to guarantee that a large part of the funded projects are directed at meeting the needs of the poor who are the most vulnerable to the impacts of climate change.
This will require political concessions from the developed world that are unlikely to be easily conceded at Copenhagen. In particular, the idea that clean technology should be a 'public good' — a resource free for everyone.
Such a commitment would significantly improve access to clean technology by those who need it most but are least able to pay. Similar to the thinking behind 'open access' to scientific research, the idea is that the easier it is to access clean technologies, the more widely the benefits will be felt.
But patents increasingly cover clean technologies — whether developed in the public or the private sector. And, despite calls for loosening patent protection, in practice the reverse is likely to happen as corporations and countries view the sale and export of green technology as a path to economic growth.
Markets not the answer
This is true for the developed and developing world alike. Countries such as China and India are already producing new technologies within a market perspective, developing them as a major future source of revenue rather than a free gift.
But, as long-argued by economists such as Nicholas Stern and increasingly accepted by governments around the world, climate change represents one of the biggest market failures of all time.
If, as with the financial crisis, it was the failure of global markets to stem excessive greed (in this case for energy) that triggered the current climate crisis, markets are unlikely to get us out of it. We need a massive public bail-out of precisely the type that the proposed MCTF represents and that governments have already provided for their financial institutions.
But those excluded from markets in the first place, including most of the world's poorest communities, need a different approach. It is here that the 'public good' approach to clean technology is most urgent.
If next month's climate talks in Copenhagen can enshrine such a commitment, it would be one of its most significant and long-lasting achievements.

Extinction crisis continues apace
From : Birdlife International
BirdLife International is the Red List Authority for birds and released the 2009 update for birds earlier in the year, listing 192 species of bird as Critically Endangered, the highest threat category, a total of two more than in the 2008 update. But the update did highlight some successes, including the downlisting of Lear's Macaw Anodorhynchus leari, from Critically Endangered to Endangered, as a direct result of targeted conservation action.
"In global terms, things continue to get worse – but there are some real conservation success stories this year to give us hope and point the way forward", said Dr Leon Bennun, BirdLife's Director of Science and Policy.
Of the world's 9,998 birds, 137 are Extinct or Extinct in the Wild, with 192 Critically Endangered, 362 Endangered and 669 Vulnerable.
The results of the full Red List update reveal 21% of mammals, 30% of amphibians, 12% of birds, and 28% of reptiles, 37% of freshwater fishes, 70% of plants, 35% of invertebrates assessed so far are under threat.
"The scientific evidence of a serious extinction crisis is mounting", says Jane Smart, Director of IUCN's Biodiversity Conservation Group. "January sees the launch of the International Year of Biodiversity. The latest analysis of the IUCN Red List shows the 2010 target to reduce biodiversity loss will not be met. It's time for governments to start getting serious about saving species and make sure it’s high on their agendas for next year, as we're rapidly running out of time."
Of the world's 5,490 mammals, 79 are Extinct or Extinct in the Wild, with 188 Critically Endangered, 449 Endangered and 505 Vulnerable. Eastern Voalavo Voalavo antsahabensis appears on the IUCN Red List for the first time in the Endangered category. This rodent, endemic to Madagascar, is confined to montane tropical forest and is under threat from slash-and-burn farming.
There are now 1,677 reptiles on the IUCN Red List, with 293 added this year. In total, 469 are threatened with extinction and 22 are already Extinct or Extinct in the Wild. The 165 endemic Philippine species new to the IUCN Red List include Panay Monitor Lizard Varanus mabitang, which is Endangered. This highly-specialized monitor lizard is threatened by habitat loss due to agriculture and logging and is hunted by humans for food. Sail-fin Water Lizard Hydrosaurus pustulatus enters in the Vulnerable category and is also threatened by habitat loss. Hatchlings are heavily collected both for the pet trade and for local consumption.
"The world's reptiles are undoubtedly suffering, but the picture may be much worse than it currently looks", says Simon Stuart, Chair of IUCN’s Species Survival Commission. "We need an assessment of all reptiles to understand the severity of the situation but we don’t have the $2-3 million to carry it out."
The IUCN Red List shows that 1,895 of the planet's 6,285 amphibians are in danger of extinction, making them the most threatened group of species known to date. Of these, 39 are already Extinct or Extinct in the Wild, 484 are Critically Endangered, 754 are Endangered and 657 are Vulnerable.
Kihansi Spray Toad Nectophrynoides asperginis has moved from Critically Endangered to Extinct in the Wild. The species was only known from the Kihansi Falls in Tanzania, where it was formerly abundant with a population of at least 17,000. Its decline is due to the construction of a dam upstream of the Kihansi Falls that removed 90 percent of the original water flow to the gorge. The fungal disease chytridiomycosis was probably responsible for the toad’s final population crash.
The fungus also affected Rabb's Fringe-limbed Treefrog Ecnomiohyla rabborum, which enters the Red List as Critically Endangered. It is known only from central Panama. In 2006, the chytrid fungus Batrachochytrium dendrobatidis was reported in its habitat and only a single male has been heard calling since. This species has been collected for captive breeding efforts but all attempts have so far failed.
Of the 12,151 plants on the IUCN Red List, 8,500 are threatened with extinction, with 114 already Extinct or Extinct in the Wild. The Queen of the Andes Puya raimondii has been reassessed and remains in the Endangered category. Found in the Andes of Peru and Bolivia, it only produces seeds once in 80 years before dying. Climate change may already be impairing its ability to flower and cattle roam freely among many colonies, trampling or eating young plants.
But it's not all doom and gloom, conservation does work and there are some great examples in this year's Red List. In Brazil, Lear's Macaw Anodorhynchus leari has been downlisted from Critically Endangered. Named after the English poet, this spectacular blue parrot has increased four-fold in numbers as a result of a joint effort of many national and international non-governmental organisations, the Brazilian government and local landowners.

Woody plants adapted to past climate change more slowly than herbs
Source: ScienceDaily, 27 September 2009
Can we predict which species will be most vulnerable to climate change by studying how they responded in the past? A new study of flowering plants provides a clue. An analysis of more than 5000 plant species reveals that woody plants — such as trees and shrubs — adapted to past climate change much more slowly than herbaceous plants did. If the past is any indicator of the future, woody plants may have a harder time than other plants keeping pace with global warming, researchers say.
In a new study, biologists at the National Evolutionary Synthesis Center (USA) and Yale University (USA) teamed up to find out how flowering plants adapted to new climates over the course of their evolution. By integrating previously published genealogies for several plant groups with temperature and rainfall data for each species, they were able to measure how fast each lineage filled new climate niches over time.
When they compared woody and herbaceous groups, they found that woody plants adapted to new climates two to ten times slower than herbs. "Woody plants eventually evolved to occupy about the same range of climates that herbaceous plants did, but woody plants took a lot longer to get there," said lead author Stephen Smith, a postdoctoral researcher at the National Evolutionary Synthesis Center in Durham, NC.
The researchers trace the disparity to differences in generation time between the two groups. Longer-lived plants like trees and shrubs typically take longer to reach reproductive age than fast-growing herbaceous plants, they explained. "Some woody plants take many years to produce their first flower, whereas for herbs it could take just a couple months," said co-author Jeremy Beaulieu, a graduate student at Yale University.
Because woody plants have longer reproductive cycles, they also tend to accumulate genetic changes at slower rates, prior research shows. "If genetic mutations build up every generation, then in 1000 years you would expect plants with longer generation times to accumulate fewer mutations per unit time," said Smith. This could explain why woody plants were slower to adapt to new environments. If genetic mutations provide the raw material for evolution, then woody plants simply didn't accumulate mutations fast enough to keep up. "If woody and herbaceous plants were running a race, the herbs would be the hares and the woody plants would be the tortoises," said Beaulieu.
By understanding how plants responded to climate change in the past, scientists may be better able to predict which groups will be hardest hit by global warming in the future. Unlike the tortoise and the hare, however, in this case slow and steady may not win the race. "Woody groups are obviously at a disadvantage as the climate changes," Beaulieu explained.
Does this mean that ecosystems dominated by trees — such as rainforests — will be more likely to disappear? Possibly, "If we look to the past for our clues, chances are trees will continue to respond much slower than herbs — as much as 10 times slower," Smith said. "But if the rate of climate change is 100 times faster, then they could all be in trouble. The kind of change we're experiencing now is so unprecedented," he added. While this study focused on long-term change over the last 100 million years, most climate models predict significant warming in the next century, the researchers explained. "That time frame may be too quick for any plant," Beaulieu said.

Study on plant breeding education to be conducted at the University of California, Davis
From : Danny Hunter (Crop Wild Relative Group)
Plant breeding is currently under stress – the global demand for breeders is greater than the current educational system has been producing. Companies are having difficulty finding well trained plant breeders, slowing the progress of
agricultural research. The need to strengthen public plant breeding programs and educate more professional plant breeders is critical if we are to continue producing improved crop varieties to provide food for an increasing population.
Researchers at UC Davis are initiating a study aimed at gaining consensus on the most essential curriculum components for educating plant breeders. Through an iterative process, a diverse group of experts with highly specialized knowledge of plant breeding will be surveyed to elicit ideas and suggestions for educational program content. Over 250 participants from all over the world will be asked to complete the three rounds of this survey, with each round building on the responses gleaned through the prior round. This consensus-based approach will lead to a comprehensive analysis of content and practical experiences that will guide the design of modern plant breeding curricula. Following conclusion of the analysis, all results will be publically available to the international community.
"Plant breeders continually provide the world with necessary advances in crop varieties; however, their numbers are diminishing due to retirements and fewer educational programs offering plant breeding degrees," says Dr. Allen Van Deynze, Director of Research at the Seed Biotechnology Center and co-founder of the Plant Breeding Academysm. "The scope of this study provides every participant an equal voice to help improve the training experiences of future breeders and will result in a clear understanding of how to focus educational programs to get the best results."
Dr. Cary Trexler, a professor in the College of Education at UC Davis will lead this study in cooperation with the Seed Biotechnology Center. Funding for this study is being provided through the generous support of private companies, university departments, and individual contributors.
