It's Not Too Late for Coral Reefs, Experts Say

ScienceDaily 3 Oct 12;

Coral reefs -- ecosystems of incredible environmental and economic value -- are showing evidence of significant degradation, but do not have to be doomed. We can make a difference.

Once plentiful, coral reefs worldwide and locally have been ravaged by a number of stresses, including global threats like rising sea temperatures and ocean acidification, and local threats like pollution, overfishing and coastal development. An estimated 25-30 percent of the world's coral reefs are already severely degraded or lost, and another very high percentage are in danger of greater impact or worse. Some even predict reefs could be essentially wiped out within a human generation unless action is taken.

The coral reef issue is not only an environmental problem, but an economic one. The United Nations estimates globally, coral reefs generate over $172 billion per year from the services they provide including tourism, recreation and fisheries. In South Florida alone, where 84 percent of the nation's reefs are located, reef ecosystems have been shown to generate over $6 billion in annual economic contributions and more than 71,000 jobs.

In July, hundreds of scientists joined in a consensus statement written at the recently held 12th International Coral Reef Symposium in Cairns Australia, stating: "Across the globe, these problems cause a loss of reef resources of enormous economic and cultural value. A concerted effort to preserve reefs for the future demands action at global levels, but also will benefit hugely from continued local protection."

Is there good news for the posterity of reefs? There can be. Research is allowing greater understanding about how reefs response to threats. Consequently, there are clear steps that must be taken to ameliorate stresses. Some of these are easy fixes that include stopping overfishing, controlling pollution and establishing marine protected areas. Others, like the rising ocean temperatures that are causing coral bleaching or the increasing acidity in our oceans, are more complex.

Research can also help us learn how to restore these valuable reefs. This includes raising corals in places where larvae and juveniles are nurtured in a relatively safe environment before being moved to a location where we can hope to restore a coral population.

Offshore coral nurseries are showing tremendous potential for restoration. A corollary, and less studied technique, is to grow corals under more controlled conditions in on-land nurseries where they are less subject to stress and variation. These specimens can then be transplanted back to degraded reefs that need a kick start. It's a fairly new idea -- and one among others that we hope will lead to increasing the tools for restoring coral reefs.

Because coral nurseries can play a significant role in restoration, we are expanding our grow-out facilities. With our new reef research facility, the Center of Excellence for Coral Reef Ecosystems Research in Hollywood, Fla., we will triple the size of our land-based coral nursery operation. Our offshore nursery research area with thousands of corals will continue its efforts. We'll use state-of-the-art facilities to study coral stressors in a controlled environment in order to better understand the impacts of these threats and how to better take corrective actions.

There are many unanswered research questions: What size of coral best survives transplantation? When is the optimum time to conduct the transplantation? What genetic strains and mix of a single species will have greatest survivorship? How are the most appropriate species for restoration? How long does it take to restore a reef?

Coral reefs are the rainforests of the sea. And like the Amazonian rainforest that's facing extreme degradation, reefs are disappearing at an alarming rate. We are embarking on a critical mission to understand and restore reef ecosystems. It's a mission that must be accomplished.

Land acquired over past decade could have produced food for a billion people

Oxfam calls on World Bank to stop backing foreign investors who acquire land for biofuels that could produce food
John Vidal The Guardian 4 Oct 12;

International land investors and biofuel producers have taken over land around the world that could feed nearly 1bn people.

Analysis by Oxfam of several thousand land deals completed in the last decade shows that an area eight times the size of the UK has been left idle by speculators or is being used largely to grow biofuels for US or European vehicles.

In a report, published on Thursday, Oxfam says the global land rush is out of control and urges the World Bank to freeze its investments in large-scale land acquisitions to send a strong signal to global investors to stop "land grabs".

"More than 60% of investments in agricultural land by foreign investors between 2000 and 2010 were in developing countries with serious hunger problems. But two-thirds of those investors plan to export everything they produce on the land. Nearly 60% of the deals have been to grow crops that can be used for biofuels," says the report.

Very few, if any, of these land investments benefit local people or help to fight hunger, says Oxfam. "Instead, the land is either being left idle, as speculators wait for its value to increase … or it is predominantly used to grow crops for export, often for use as biofuels."

The bank has tripled its support for land projects to $6bn-$8bn (£3.7bn-£5bn) a year in the last decade, but no data is available on how much goes to acquisitions, or any links between its lending and conflict.

Since 2008, says Oxfam, 21 formal complaints have been brought by communities affected by World Bank investments, in which they claim that these have violated their land rights.

Oxfam's chief executive, Barbara Stocking, said: "The rush for land is out of control and some of the world's poorest people are suffering hunger, violence and greater poverty as a result. The World Bank is in a unique position to help stop land grabs becoming one of the biggest scandals of the century."

She added: "Investment should be good news for developing countries – not lead to greater poverty, hunger and hardship."

According to the International Land Coalition, 106m hectares (261m acres) of land in developing countries were acquired by foreign investors between 2000 and 2010, sometimes with disastrous results.

Nearly 30% of Liberia has been handed out in large-scale concessions in the past five years, and up to 63% of all arable land in Cambodia has been passed over to private companies.

Oxfam dismisses the claim made by the World Bank and others that lots of available land is unused and waiting for development. "It is simply a myth. Most agricultural land deals target quality farmland, particularly land that is irrigated and offers good access to markets.

"It is clear that much of this land was already being used for small-scale farming, pastoralism and other types of natural resource use."

A 2010 study by the Independent Evaluation Group (IEG) – the World Bank's official monitoring and evaluation body – stated that about 30% of bank projects involved involuntary resettlement. The IEG estimated that at any one time, more than 1 million people are affected by involuntary resettlement in active World Bank-financed projects.

Oxfam urged the UK government, one of the bank's largest shareholders, to use its influence to persuade it to implement the freeze. "It can also play a crucial role as president of the G8 next year by putting food and hunger at the heart of the agenda, and addressing land grabs as part of this. Critically, it can also press the EU to reverse biofuels targets – a key driver of land grabs."

Stocking said: "The UK should also show leadership in reversing flawed biofuels targets, which are a main driver for land and are diverting food into fuel."

In a statement to the Guardian, the International Finance Corporation, the World Bank's private lending arm, said: "IFC does not finance land acquisitions for speculative purposes. We invest in productive agricultural and forestry enterprises that can be land intensive to help provide the food and fibre the world needs. IFC has roughly a $4.85bn portfolio of agri-related investments. Of that, roughly $600m has a land component. Total land holding related to those investments total 0.7m hectares.

"Competition for scarce land resources has spurred rising investment in land. This competition can fuel conflict with existing users. Inevitably, bank group involvement in forestry and agriculture is not without risk, particularly given the fact we are operating in imperfect governance environments. But the total number of complaints received gives no explanation as to their validity."
