  • Introduction
  • Forests cover a third of our land on the planet earth
    They provide raw materials, maintain
    biodiversity, protect land and water resources, and play a role in climate change mitigation
    Forests are heavily exploited
  • they can be damaged by fire, agricultural and urban expansion, and other disturbances
  • Ten countries with largest forest areas (million ha)
  • How much forest is there on the planet and at what rate is it disappearing?
  • 30% of the global total land area is covered by forests
    Forest area decreased worldwide by 0.22% per year in the period 1990-2000 and 0.18% per year between 2000 and 2005.
    Primary forests account for over a third of global forest area
  • Forest plantations are increasing but make up less than 5% of overall forest area
  • Forest characteristics (%)
  • How can forests affect climate change?
  • by affecting the amount of carbon dioxide
    carbon is removed from the atmosphere and absorbed in wood, leaves and soil
    Forests are known as ‘ carbon sinks ‘
    forest ecosystems store more carbon than the entire atmosphere
  • Growing stock is a measure of the volume of stem wood in a given area of forest or wooded land
    Carbon stock refers to the amount of carbon stored in the world’s forest ecosystem
  • Total Carbon Stock (C) in forests by region
  • What is the biological diversity of the world’sforests?
  • Biological diversity allows forest ecosystems to adapt continuously to changing conditions and to maintain their potential for meeting human needs
    The amount of primary forest provides a basic indication of biodiversity
    Protected areas of forest are important to conserve biological diversity
  • The number of native tree species found in different countries varies greatly
    Rare tree species and those with high economic value are often in danger of becoming locally extinct
  • Ten countries with the largest area of primary forest (%)
  • Number of native forest tree species
  • How healthy are the world’s forests?
  • Forests can be damaged by disturbances such as fires, airborne pollution, storms, invasive species, pests, diseases, and insects
    About 1% of forests (an area roughly the size of New Zealand) are consumed by fire each year
    Problems caused by insects and diseases have increased in recent years
  • Other forest disturbances include climatic factors such as wind, snow, ice, floods, tropical storms and drought, or impacts of animals
  • What products are extracted from forests?
  • Forests provide a wide range of products, not only timber and fuel wood, but also products such as food (berries, mushrooms ,etc.) and fodder
    One third of the world’s forests are used primarily for production of wood
    Growing stock is the amount of stemwood in a given area
  • Volume of timber and fuel wood harvested has remained constant
    Non-wood products provided by forests include food, fodder, and medicinal plants
  • Five countries with greatest total growing stock (%)
  • Ten countries with largest area of productive forest plantations (%)
  • What are the protective effects of forests?
  • conservation of ecosystems
    in maintaining clean water
    in preventing or reducing the severity of floods, avalanches, erosion and drought
    An increasing area of the world’s forests is designated primarily for soil and water conservation
  • Recognizing the important protective role of forests, many countries have planted trees for this purpose
  • Designated functions of forests globally (%)
  • What are the economic and social benefits of forests?
  • Forests provide a wide range of economic and social benefits
    The total value of harvested timber and fuelwood was about US$64 billion
    The total global reported value of non-wood forest products was US$4.7 billion
  • 10 million people are employed in forestry
    Most of the world’s forests are publicly owned (84%), but private ownership is increasing
    Use of forests for recreation and education is increasing
  • Are forests managed in a sustainable way?
  • There are many good signs and positive trends, but also many negative trends
    At the global level, there has been a decrease in the area of forest
    In Africa, overall, there was limited progress
    In Asia, progress has been mixed
  • In Europe, the status of forest has mainly been stable
    Forest management has progressed in North and Central America as a whole
    Progress in South America was mixed
    Within world regions there are local differences
  • Ownership of forests by subregion
  • And what about tribal people?
  • Conclusions
  • Deforestation continues at an alarmingly high rate, but that the net loss of forest area is slowing down
    If managed sustainably, forests also contribute significantly to local and national economies
    Overall, progress towards sustainable forest management has been mixed

  • Any Questions?
  • Thank You
