    Global review of forest pests and diseases
    A thematic study prepared in the framework of the Global Forest Resources Assessment 2005
    2009
    Also available in:

    Insect pests, diseases and other biotic agents have considerable impacts on forests and the forest sector. They can adversely affect tree growth and the yield of wood and non-wood products. Damage caused by forest pests can significantly reduce wildlife habitat thereby reducing local biodiversity and species richness. They can alter natural forest landscapes by decimating one or more tree species as has been observed in eastern American forests as a result of chestnut blight and throughout the Northern Hemisphere because of Dutch elm disease. Some pests have necessitated changes in management regimes often forcing forest managers to switch to alternative tree species in plantations; for example, the failed attempts in many parts of the world to establish mahogany plantations because of the presence of mahogany shoot borers ( Hypsipyla spp.). Pathogens may also limit the sites on which species can be gro wn successfully outside their natural range as has been experienced with red band needle blight (Mycosphaerella pini) and western gall rust (Endocronartium harknessii)infecting Pinus radiata.

    Climate change impacts on twenty major crop pests in Central Asia, the Caucasus and Southeastern Europe 2021
    Also available in:

    This research report for a regional study on the impacts of climate change on the spread of pests contributes to FAO’s normative work, as a milestone for 2020–2021 under the Regular Programme. The year 2020 was designated by the United Nations as the as the International Year of Plant Health (IYPH), with the aim of reducing crop loss from pests, which is estimated at 40 percent. In the current report, agricultural pests as any organism harmful to plants, including viruses, bacteria, fungi, nematodes, insects, etc are defined by the authors. We include those that cause direct damage as well as disease-causing organisms. Climate change is projected to worsen crop losses by another 10–25 percent, which in some regions would emanate from associated pests. Central Asia, the Caucasus and Southeastern Europe are under the research area.

    Forest threats 2004
    Also available in:

    Forests have long been threatened by a variety of destructive agents. Today, the frequency, intensity and timing of fire events, hurricanes, droughts, ice storms and insect outbreaks are shifting as a result of human activities and global climate change, making forest ecosystems even more prone to damage. This issue of Unasylva examines the threats posed by a number of biotic and abiotic agents and some of the measures for overcoming them.
