  • Erosion after wildfires affect forest rehabilitation

    Wildfires greatly increase hillslope- and watershed-scale runoff and sediment yields, according to research conducted by a group from Colorado State University and published in the Soil Science Society of America Journal. Land use and climate change have increased, or are projected to increase, the size and frequency of fires in many wildland environments. These issues are of concern because ...

  • All for forests, forests for all!

    An unprecedented large group of governments, companies, NGOs and indigenous peoples groups called for action to protect and restore the world’s forests. In a declaration launched at this week’s UN climate talks in New York, targets ...

  • Erosion of forests and grasslands triggers alarm bells in Asia and the Pacific

    Forest loss and degradation remain major problems confronting the Asia-Pacific region which, if not addressed, will leave future generations a legacy of damaged ecosystems and irrecoverable losses of biodiversity, FAO is warning. Forest and grasslands cover 57.5 percent of Asia-Pacific’s massive land surface and provide vital ecosystems that support agriculture and livelihoods, which in ...

  • Protecting against erosion after wildfire

    Soil erosion after wildfire can be substantially reduced by using a combination of sowing grass seeds and protecting the soil with a layer of straw, a Spanish study suggests. The authors of the research found that, although seeding alone made little difference, the combination of straw mulch and seeding reduced soil erosion by 93%. The European countries that are worst affected by wildfires are ...

  • Role of forests in climate change

    A three-day meeting of Directors-General for Forestry began on Tuesday in Slovenia. The main topics of the meeting concern forests and climate change, and the question of what role forests should play in adapting to and mitigating climate change. The Directors-General will also discuss the initiative for concluding a legally binding agreement on forests in Europe which was previously ...

  • Restoring forests: an opportunity for Africa

    New research shows that Africa offers some of the greatest opportunities globally for restoring forests. This post originally appeared on Mongabay. Tropical forest news last week was dominated by Indonesia and Brazil. Forest clearing has surged over the past year in parts of ...

  • Putting People at the Centre of Forest Policies - The State of the World`s Forests (SOFO)

    Countries should put more policy emphasis on maintaining and enhancing the vital contributions of forests to livelihoods, food, health and energy, the UN Food and Agriculture Organization (FAO) said today. FAO's flagship publication The State of the World's Forests(SOFO), presented today at the opening of the 22nd Session of the  ...

  • Mangroves declining faster than forests

    The first global assessment of mangroves in over a decade reveals that rare and critically important mangrove forests continue to be lost at a rate three to four times higher than land-based global forests, despite positive restoration efforts by some countries. About one fifth of all mangroves are thought to have been lost since 1980. Although losses are slowing at 0.7% a year, the authors warn ...


  • Impact of climate change on forests requires early action

    Early action and more investments are needed to respond to the threats of climate change on the world's forests. It will probably cost less to adjust forest management strategies immediately to the impacts of climate change than to react to the aftermath of climate-inflicted damage, FAO said in its new Climate change guidelines for forest ...

  • Restoring the world`s forests while feeding the poor

    “We are one shock away from a full-blown crisis,” stated Robert Zoellick, the president of the World Bank, at a recent meeting of the bank and the IMF. He was referring to a critical increase in poverty, resulting from the escalating cost of food. The UN’s food price index has risen 37% since March ...

  • Property tax incentives for forest conservation in the U.S. South

    Development pressure on the outskirts of cities throughout the southern United States drives up land values and makes it more difficult for private landowners to keep their forestland. On average, in the South, short term returns for development can be $36,000 per acre. And for private landowners who want to keep their ...

  • Growth-oriented logging: a new concept in forest management

    Deforestation in the tropics has both local and global effects, but conservation remains a major challenge. New research describes a method for measuring tree growth and timber harvesting, which can lead to sustainable management of tropical timber resources. The method tailors cutting cycles according to accurate growth rates of different tree species. Research explored the Mamirauá Sustainable ...

  • Global well-being: rooted in the world`s forests

    This piece originally appeared in the Washington Post Environmental Leadership supplement on April 20, 2011, and is reposted with permission. This year, 2011, has been declared the International Year of Forests, and while a few bright spots exist, forests today face a host of challenges. Mounting pressures from agricultural expansion, rapid economic development, and growing demand for products ...

  • Improving livelihoods for poorer forest dwellers in Nepal

    Community forestry in Nepal claims to be a successful model of participatory, community-based forest management, and there is considerable evidence that it is improving forest protection and regeneration. However, community forestry makes only a limited contribution to improving rural livelihoods. New research suggests that social factors may be limiting the access of poorer households to ...

  • Preventing rangeland erosion: Developing better management practices in Iran

    The rangelands of Iran have one of the world’s longest history of agriculture development, with a deep tradition of technological developments and knowledge of the soil that has produced centuries of fertile crops. Currently, however, new pressures to feed an increasing population of humans and livestock in the region has taken its toll on the land, as evidence now suggests that the soil is ...

  • Rejuvenating arid badlands: from barren slopes to living forest in 80 years

    A reforestation project has revitalised its surroundings just 80 years after its inception. In the late 1920s, the Saldaña badlands in northern Spain were a barren region, with a thin layer of intensely weathered soil, and only 5% vegetation cover. Now that cover has increased dramatically to 87%, the soil quality is improving, and the water flow in the area has stabilised, bringing ...

  • High gold prices drive expansion of mining activity in the Amazon forest of Peru

    Gold mining areas in the Peruvian Amazon rainforest expanded from under 10 000 hectares in 1999 to over 50 000 hectares by 2012, and now destroys more forest than agriculture and logging combined, new research has shown. Using high-resolution satellite imaging, researchers estimated gold mining areas to be twice as large as estimated by previous studies, which did not include the combined effects ...

  • Forest fires in Southern Europe destroy much more than trees

    Forest fires in Spain, France, Italy and Greece burned more than 50 000 hectares in the last four days. The economic and environmental damage caused by such fires extends well beyond the affected areas. Damage to biodiversity and livelihoods may take decades to reverse. Fires rank among the top causes of damage to Europe's forests. Every year forest fires burn, on average, about 500 000 hectares ...

  • Pine plantations provide optimum conditions for natural forests to develop underneath them

    If there is any native forest in the vicinity, tree, fern and herbaceous species typical of these forests penetrate under the pine plantations without any need for action. That way it is possible, to a certain extent, for native forests to be restored, thanks to the process known as ecological succession. This is the conclusion reached by the UPV/EHU’s Landscape, Biodiversity and Ecosystem ...

  • Multifunctional forests - balancing timber, water and carbon sink needs air

    Traditionally, forests have needed different management programmes depending on their purpose, for example, whether the priority is to maximise their value in terms of timber, water or as a carbon sink. However, the integration of these values in management strategies has become increasingly important. A new study has explored one means of achieving this, by placing an economic value on fresh ...
