Study finds half of UN projects do not engage local communities in monitoring, argues REDD+ projects that integrate community participation are more likely to save forests



OSLO, NORWAY (29 October 2013)As global forest and climate experts gather at the Oslo REDD Exchange 2013 to ramp up international efforts to protect carbon-storing forests in the developing world, a recent study by researchers at the Nairobi-based World Agroforestry Centre (ICRAF) and European and Southeast Asian institutions finds that local communitiesusing simple tools like ropes and stickscan produce forest carbon data on par with results by professional foresters using high-tech devices.


At the same time, the study found that nearly half of official REDD+ (Reducing Emissions from Deforestation and Forest Degradation) projects, which pivot on the accurate measurement of carbon trapped in forests, do not engage communities in this data gathering, despite assertions by the United Nations that these projects must ensure communities' "full and effective participation." The authors of the paperthe first-ever quantitative study of REDD+ community participationargue that locally-gathered data is not only accurate but also more legitimate and cost-effective in the long run. It also improves trust in REDD+ among local communities.


"Saving the world's forests requires us to close the massive gulf between international promises and realities on the ground," said Finn Danielsen, the study's lead author and senior ecologist at the Nordic Foundation for Environment and Development in Copenhagen, Denmark. "Our research shows that if more REDD+ projects were to include community monitoring, we would see a more just global effort to fight climate change that meaningfully incorporates insight from people who depend on forests for everything from their incomes to their foodand are eager to protect these precious natural resources as a result."


The studyCommunity Monitoring for REDD+: International Promises and Field Realitieswas authored by 22 scientists and was based on a study conducted in Southeast Asia's most complex, carbon-rich forests: lowland forest in Indonesia, mountain rain forest in China and monsoon forest in Laos and Vietnam. It was published in a special issue of the journal Ecology and Society. The study is part of the EU-funded project Impacts of Reducing Emissions from Deforestation and Forest Degradation and Enhancing Carbon Stocks (I-REDD+).


To determine if communities can provide accurate monitoring of above-ground forest-carbon stocks, researchers trained community members in simple measuring tactics and sent them to 289 pre-selected forest plots to measure the number of trees, tree girth and biomass per hectare. Researchers then compared their measurements to those gathered by professional foresters using handheld computers.


The results showed strikingly similar results between community members and professional foresters across countries and forest types. This corroborates a small but growing body of research suggesting that, when armed with the simplest of techniques and equipment, community members with limited education can accurately monitor forest biomasspreviously thought to be the domain of highly-trained professionals. The authors also state that data gathered by communities meet the high standards of the United Nations Intergovernmental Panel on Climate Change's (IPCC).


The study is the most comprehensive assessment undertaken to date of the ability of community members to accurately monitor forest resources.


Community forest monitoring is also cheaper in the long run. Researchers compared costs per plot, finding that while professional monitoring can be less expensive in the short-termUS$22-$53 as opposed to US$39-$82 for community-led effortsmodest investments in training could, over time, make community-led monitoring a cheaper alternative.


"We're convinced that engaging communities is ultimately the most cost-effective approach. The small extra cost would be largely offset by its benefits to both local peoplewho would earn wages and gain training from these activitiesand larger global efforts to address climate change," said Subekti Rahayu, an analyst at ICRAF who conducted fieldwork for the study.


The study argues that community-gathered data would strengthen current REDD+ projects. It can be used, for example, to double-check remote sensing or modeling data gathered by researchers from afar. It can also be used to earn "buy-in" from local people, who, according to researchers, would be more likely to trust and participate in REDD+ activities if they are treated as equals in the process and are ensured continued access to the forests they rely on for their incomes.


Despite agreement among all parties that REDD+ must include local communities, local engagement is lagging, said the study's authors.


"The legitimacy of international efforts to reduce emissions from deforestation rests on community involvement," said Meine van Noordwijk, Chief Science Advisor at ICRAF. "Yet international promises to engage local people have gone largely unfulfilled."


The study finds that obstacles to effective community engagement stem from a lack of awareness; foresters who train local people are simply not aware of low-tech methods and their accuracy. In addition, skills among local people vary, as do monitoring methods. The authors call for the development of, and better training in, simple, standardized monitoring methods that can be deployed across the world's forest nations.


"The roadblocks are ultimately surmountable," said Peter Minang, a scientist at ICRAF and an expert on community forestry in developing countries. "With the accuracy of community-gathered data now confirmed, the international community has little excuse to exclude local people from participating in knowledge gathering to better understand and fight climate change."

Storm with hurricane-force winds kills 13 in Europe


LONDON (AP) — A savage coastal storm powered by hurricane-force gusts slashed its way through Britain and western Europe on Monday, felling trees, flooding lowlands and snarling traffic in the air, at sea and on land. At least 13 people were reported killed.

It was one of the worst storms to hit the region in years. The deadly tempest had no formal name — and wasn't officially classified as a hurricane due to a meteorological standard — but it was dubbed the St. Jude storm (after the patron saint of lost causes) and stormageddon on social networks.

Gusts of 99 miles per hour (160 kph) were reported on the Isle of Wight in southern England, while gusts up to 80 mph hit the British mainland. Later in the day, the Danish capital of Copenhagen saw record gusts up of to 120 mph (194 kph) and an autobahn in central Germany was shut down by gusts up to 62 mph (100 kph).

All across the region, people were warned to stay indoors. Hundreds of trees were uprooted or split, blocking roads and crushing cars. The Dutch were told to leave their beloved bicycles at home for safety's sake.

At least thirteen storm-related deaths were reported, most victims crushed by falling trees. Germany had six deaths, Britain had five and the Netherlands and Denmark had one each. One woman was also missing after being swept into the surf in France.

Two people were killed in London by a gas explosion and a British teen who played in the storm-driven surf was swept out to sea. A man in Denmark was killed when a brick flew off and hit him in the head.

Despite the strength of its gusts, the storm was not considered a hurricane because it didn't form over warm expanses of open ocean like the hurricanes that batter the Caribbean and the United States. Britain's national weather service, the Met Office, said Britain does not get hurricanes because those are "warm latitude" storms that draw their energy from seas far warmer than the North Atlantic. Monday's storm also did not have an "eye" at its center like most hurricanes.

London's Heathrow Airport, Europe's busiest, cancelled at least 130 flights and giant waves prompted the major English port of Dover to close, cutting off ferry services to France.

Nearly 1,100 passengers had to ride out the storm on a heaving ferry from Newcastle in Britain to the Dutch port of Ijmuiden after strong winds and heavy seas blocked it from docking in the morning. The ship returned to the North Sea to wait for the wind to die down rather than risk being smashed against the harbor's walls, Teun-Wim Leene of DFDS Seaways told national broadcaster NOS.

In central London, a huge building crane near the prime minister's office crumpled in the gusts. The city's overburdened transit system faced major delays and cancellations and did not recover even once the weather swept to the east.

A nuclear power station in Kent, southern England, automatically shut its two reactors after storm debris reduced its incoming power supply. Officials at the Dungeness B plant said the reactors had shut down safely and would be brought back once power was restored.

The storm left Britain in the early afternoon and roared across the English Channel, leaving up to 270,000 U.K. homes without power.

Trains were canceled in southern Sweden and Denmark. Winds blew off roofs, with debris reportedly breaking the legs of one man. Near the Danish capital of Copenhagen, the storm ripped down the scaffolding from a five-story apartment building.

Copenhagen's Kastrup Airport saw delays as strong gusts prevented passengers from using boarding bridges to disembark from planes to the terminals.

In Germany, the death toll hit six, with four people killed in three separate accidents Monday involving trees falling on cars, the dpa news agency reported. A sailor near Cologne was killed Sunday when his boat capsized and a fisherman drowned northeast of the city.

In addition to widespread rail disruptions, both Duesseldorf and Hamburg airports saw many flights cancelled, stranding more than 1,000 passengers.

Thousands of homes in northwestern France also lost electricity, while in the Netherlands several rail lines shut down and airports faced delays. Amsterdam's central railway station was closed due to storm damage.

In France, maritime officials were searching for a woman who was swept into the turbulent Atlantic by a big wave Monday as she walked on Belle Isle, a small island off the coast of Brittany.

"We are focused on the search," Yann Bouvart, of the Atlantic Maritime Prefecture told BFM-TV. He said a helicopter, a boat and an inflatable Zodiac were looking for the woman.

Amsterdam was one of the hardest-hit cities as the storm surged up the Dutch coast. Powerful wind gusts toppled trees into canals in the capital's historic center and sent branches tumbling onto rail and tram lines, halting almost all public transport. Commuters faced long struggles to get home.

Ferries in the Baltic Sea, including between Denmark and Sweden, were canceled after the Swedish Meteorological Institute upgraded its storm warning to the highest possible level, class 3, which indicates "very extreme weather that could pose great danger."

Trains were canceled in southern Sweden, and many bridges were closed between the islands in Denmark.

London Mayor Boris Johnson praised emergency workers for doing an "amazing job" trying to keep London moving. He said his thoughts, along with those of all Londoners, were with the victims and their loved ones.

Findings could help define new vaccination applications



MINNEAPOLIS/ST. PAUL (October 27, 2013) New research from the Masonic Cancer Center, University of Minnesota, and the University of Minnesota Center for Immunology has identified key proteins that influence immune response strategies, a finding that could influence new vaccination approaches.


The study, published in the latest edition of Nature Immunology, looked closely at the KLF2 and S1P1 genes, and how their expression impacted the immune strategy of a cell.


The immune system has two main strategies to empower white blood cells, or lymphocytes, to resist infections of the body.


The first strategy, called recirculation, is a process where white blood cells are carried around in circulating blood, allowing rapid access to organs once an immune response has begun.


The second major strategy allows lymphocytes to migrate into tissues and remain there long-term, creating a kind of rapid response team to any infectious organism that enters the body. These cells are called resident memory T-cells or Trm, and they play a dominant role in initiating immune responses that control infections.


"A key question we had was how lymphocytes make the choice to be a recirculator or a resident," said Stephen Jameson, Ph.D., a professor in the Center for Immunology and Department of Laboratory Medicine and Pathology in the University of Minnesota Medical School. "We already knew the protein KLF2 regulates the expression of genes. One of those genes, called S1P1, allows lymphocytes to leave tissues and begin recirculating."


Intrigued by the impact of KLF2 and S1P1 on lymphocytes' ability to move out of tissues, Jameson and colleagues wanted to compare resident and recirculating cells and the KLF2 and S1P1 levels. They found that resident T-cells had lost expression of the KLF2 and S1P1 genes.


The next step was finding what controlled the expression of KLF1 and S1P1. Jameson's team was able to pinpoint cytokines as playing a major role in this cell decision-making process.


"Cytokines are soluble proteins that act similar to hormones for the immune system," said Jameson. "We found the cytokines can instruct cells to become resident memory cells, thereby may be useful for bolstering local immunity."


Though further research is needed to define the biochemical signals dictating how recirculation versus residency is chosen, learning more about these key signals instructing T-cells to determine their strategic immunity role could significantly improve vaccination approaches. Researchers may be able to use the knowledge and develop technology to focus memory T-cells to form a barrier to infections.

Apple: The iPhone 5c is our 'mid-tier' model



Just in case Apple's pricing scheme didn't make things crystal clear, CEO Tim Cook may have just set one thing to rest during today's earnings call: The iPhone 4s is the company's entry level model, and the 5c -- once said to be tailored for emerging markets and targeting more price-sensitive consumers -- is officially Apple's mid-tier model.


Responding to a question about iPhone pricing strategy, Cook was adamant that claims that the 5c was ever intended as an entry-level model were strictly rumors, and that it "was never our intent." The 4s, he said, is the entry-level model, and is a "fantastic product," with access to the entire iOS ecosystem.
