ENVIRONMENT / FORESTS - WORLD II

Involving local groups has been a key factor in halting the loss of forest cover in the Asia-Pacific region, a UN study has concluded.

The report found that low-cost projects offered communities an incentive to protect the habitats in return for job opportunities and income sources.

Such schemes also enhanced ecosystems, restored biodiversity and increase carbon storage, the authors added.

The results were published at the start of the UN Asia-Pacific Forestry Week.

Despite the threats from illegal deforestation, forest fires and climate change, the Forest Beneath the Grass report - produced by the Food and Agriculture Organization (FAO) - said the region had "not only stopped the drastic decline in forest cover of the 1990s", but had actually increased tree cover over the past decade.

"The Asia-Pacific region has accomplished this feat of reversing the trend of forest loss faster than any other region in history," said Eduardo Rojas, assistant director-general of the FAO's Forestry Department.

Helping hand

The report credited "assisted natural regeneration" (ANR) projects as one of the key factors in turning the net loss of tree cover into an annual net gain.

ANR is a forest restoration and rehabilitation technique that converts grass dominated areas into productive forests, based on the natural process of plant succession, encouraging the regeneration and growth of indigenous tree species.

One of the most invasive grass species is Imperata cyclindrica, also known as blady grass. Native to the region, it thrives on disturbed soil - such as roadsides and felled forests. Once established, it quickly forms a monoculture and suppresses other species from becoming established.

As opposed to more resource-intensive programmes, such as agro-forestry schemes or large-scale plantation projects, the authors highlighted how ANR schemes were relatively passive and cheap, allowing local communities to become actively involved.

They added that while the vast grasslands provided grazing sites for cattle and roofing material, there were relatively few other benefits when the potential productivity of the area was taken into account.

The scheme follows a number of stages, including:

  • site selection,
  • modifications to encourage growth of preferred species,
  • possible supplementary planting,
  • site protection and monitoring.

"The success of ANR is dependent on the effective involvement of local residents in its implementation," explained FAO senior forestry officer Patrick Durst, who presented the report's findings at a news conference in Beijing.

"It is important that local communities are given incentives and ultimately benefit from [the] programmes."

The benefits come in a number of guises, such as a diversity in harvestable crops, cost-effective land management, hunting grounds, and improved ecological services.

According to the FAO's Global Forest Resources Assessment, the region recorded an average annual net gain of 1.5m hectares of tree cover over the past decade.

However, deforestation remains a global concern, with 13m hectares - with a large volume being primary, natural forests - being lost each year over the same period.

Mr Rojas observed: "The rate of deforestation is still very high in many countries and the area of primary forest - forests undisturbed by human activity - continues to decrease.

"Countries must further strengthen their efforts to better conserve and manage them."

ENVIRONMENT / FORESTS - WORLD

Healthy forests key for green growth, says UN report

But the report's authors said that nations needed to do more to ensure the right policies are in place if forests are to meet their maximum potential.

In another initiative, an international collaboration has pledged to restore 18 million hectares of wooded landscapes.

The findings were launched at the Rio+20 summit in Brazil.

"Forests and trees on farms are a direct source of food, energy and income for more than a billion of the world's poorest people," said Eduardo Rojas-Briales, assisant director-general for Forestry at the UN Food and Agriculture Organization (FAO).

"At the same time, forests trap carbon and mitigate climate change, maintain water and soil health, and prevent desertification," he added.

"The sustainable management of forests offer multiple benefits - with the right programmes and policies, the sector can lead the way towards more sustainable, greener economies."

The report, The State of the World's Forests 2012, the 10th in the SOFO series, highlighted some of the main avenues in which money could figuratively grow on trees, including:

  • Critical life support systems - can perform a range of "essential ecosystem funtions", such as regulating water supplies and buffering floods and droughts.
  • "Engine of economic development" - SOFO highlights strong link between reforestation and growth, and deforestation and economic decline, hence the anti-poverty role of forests.
  • "Key component of greening other sectors" - wood is still the primary energy source for one-third of the world's population, therefore - with the right policies - it can expanded to provide a global greener, cleaner energy source.

The report, launched at the R+20 summit in Rio De Jainero, concluded that forests and forest products "will not solve the challenges of moving towards greener economies, but they will provide excellent examples and a source of hope".



Rising to the challenge

Also being announced at the summit was a joint pledge between a number of nations and NGOs to restore more than 18 million hectares of forest landscape.

The US and Rwanda goverments teamed up with the Brazilian Mata Atlantica Forest Restoration Pact (made up from government agencies, NGOs, private sector bodies and indigenous groups).

The annoucement forms part of the "Bonn Challenge", which was agreed in September 2011 and commits nations to restore 150 million hectares of forested areas by 2020.

"The largest restoration initiative the world has ever seen is now underway," said Julia Marton-Lefcvre, director-general of the International Union for Conservation of Nature (IUCN).

"[It] will provide huge global benefits in the form of income, food security and addressing climate change," she added.

"We urge other countries and landowners to follow suit."

The IUCN is involved in promoting Plant a Pledge, an online campaign to build public support for the Bonn Challenge.

Organisers hope people will sign a petition, which will be presented by campaign ambassador Bianca Jagger at the UN Climate Change talks in November.
