Vital Forest GraphicsVital Forest Graphics
Forests are not only important for the 1.6 billion people who depend on them for their livelihoods, but for the world's population at large. Forests play a critical role in the Earth's life support system, including global carbon and hydrological cycles. To help communicate the value of forests to policy/makers and the wider public, three United Nations organizations / entities UNEP, FAO and UNFF joined efforts to analyse, synthsize and illustrate tropical forest issues. The Vital Forest Graphics provides an overview of the global trends in forest cover and looks specifically at the four largest forest ecosystems and analyses the trends and challenges in their conservation and management. It scrutinizes some of the key drivers behind forest loss, including the increasing demand for commodities and energy. Finally, it reviews some of the best practices for sustainable management of forest, including management of forest, including regulatory regimes, participatory management and economic incentives.

Historical Forest Carbon Balance 1855-1995 Historical Forest Carbon Balance 1855-1995
Through processes of respiration and through the decay of organic matter or burning of biomass, forests release carbon. A carbon ‘sink’ is formed in the forest when the uptake of carbon is higher than the release. The conversion of forested to nonforested areas in developing countries has had a significant impact on the accumulation of greenhouse gases in the tmosphere, as has forest degradation caused by over-exploitation of forests for timber ...

Global Biofuel Production Global Biofuel Production
Demand for land for production of biomass for energy is putting increasing pressure on forests. Energy security concerns, high oil prices and climate mitigation policies aimed at replacing fossil fuels with renewable energy, have all led to a greater interest in biofuels. The transport sector is using increasing quantities of ethanol, mainly produced from sugar cane, corn and cassava, as a substitute for petrol (gasoline), and biodiese...

The Routes of African Ivory and Rhino Horns to Asia The Routes of African Ivory and Rhino Horns to Asia
In Central Africa, species under threat from poaching include elephants and rhinos. Rhinoceros horn is used in traditional Asian medicine, believed to reduce fevers and even prevent loss of life. Other parts of the rhino, including the skin and bones, are also used for their supposed medicinal qualities. Demand for rhino horn has increased substantially in recent years.

Solid Biomass Consumption Including Woodfuel Solid Biomass Consumption Including Woodfuel
Fuelwood and charcoal from forests have long provided energy for heating, cooking and industry. Almost 90 per cent of the wood harvested in Africa, and 40 per cent in Asia and the Pacific, is used for fuel (FAO 2006a). Wood pellets, typically produced in North America and Europe from sawdust and other timber by-products, are increasingly used in stoves, boilers and power stations (Peksa-Blanchard et al. 2007)

Trends in Area of Productive Forest Plantations Trends in Area of Productive Forest Plantations
In 2005, 2.8 per cent of total global forest cover was made up of productive forest plantations, amounting to an area of approximately 110 million hectares (FAO 2006a). According to the FAO, there was an increase of approximately 40 per cent in the area of the world’s forests plantations with productive functions in the 15 years from 1990. Studies indicate that this growth – a marked trend in recent years – is set to continue (e.g., MA...

Forests Regulate Groundwater Level Forests Regulate Groundwater Level
Forests can regulate groundwater levels and increase drainage of soils where the water table is close to the surface. If there are salts in the upper soil layers, then removal of forests can result in raised groundwater levels and the movement of salts into the rooting zone of plants (FAO 2008c).

The Amazon is now part of a national and international economy which, through globalization, is responding to market demands, accelerating the rate at which agricultural crops and cattle ranching are replacing or impoverishing native forests.

Tea Production Areas and Forest Distribution in Kenya Tea Production Areas and Forest Distribution in Kenya
The micro-climate associated with forest areas is often a critical factor in growing cash crops. In East Africa, tea is grown in areas adjacent to montane forests where conditions for tea production are optimal due to constant moisture levels, air temperatures between 10° and 30° C and soil temperatures between 16° and 25° C. The high moisture levels in these montane forests combined with the high heat capacity of water reduces the day...

Forests Affected as Hideouts and Refuges Forests Affected as Hideouts and Refuges
Around the world, conflicts and wars are, directly and indirectly, taking a toll on forests and the communities that rely on them for their livelihood. Dense forests in remote areas provide safe haven for refugees fleeing from conflict, which can result in overexploitation of forest resources.

Carbon Stocks Trends and Projections Compared to 1860 Carbon Stocks Trends and Projections Compared to 1860
Carbon stocks in forest areas comprise carbon in living and dead organic matter both above and below ground including trees, the understorey, dead wood, litter and soil. According to the latest projections, changes in climate will mean that by 2050 the world’s ecosystems, including all its important forests, will be releasing more carbon than they are capable of absorbing.

Major Producers of Palm Oil and Beef Major Producers of Palm Oil and Beef
Indonesia and Malaysia are major producers of palm oil: in 2006 these two countries accounted for 85 per cent of total world production and 88 per cent of global exports (FAO 2008). Over the past decade, the area covered by oil palms in Indonesia has quadrupled, covering 4.1 million hectares in 2006 (FAO 2008). In Latin America, cattle ranches are expanding rapidly (FAO 2007a) and, according to one study, accounted for an estimated 70 pe...

The World is Losing its Mangroves The World is Losing its Mangroves
Mangrove forests occur naturally in intertidal zones along sheltered shorelines and in deltas in tropical regions. They are vital breeding grounds for fish and shrimp and also provide a buffer against coastal hazards such as storms, cyclones, wind and salt spray by reducing wind and wave action (Braatz et al. 2007).

In Latin America, cattle ranches are expanding rapidly (FAO 2007a) and, according to one study, accounted for an estimated 70 per cent of deforestation in Brazil in 2007 (Malhi et al. 2008). In the Brazilian Amazon region, ranches cover an area of at least 8.4 million hectares in total.

Amazonian Deforestation in the Global Context Amazonian Deforestation in the Global Context
Growing global demand for land for the production of agricultural commodities has resulted in sometimes irreversible changes to the world’s forest cover. The Amazon is now part of a national and international economy which, through globalization, is responding to market demands, accelerating the rate at which agricultural crops and cattle ranching are replacing or impoverishing native forests (Nepstad et al. 2006).

Forests and Conflicts Forests and Conflicts
Around the world, conflicts and wars are taking a toll on forests and on the communities that rely on them for their livelihood. Dense forests can serve as hideouts for insurgent groups or can be as a vital source of revenue for warring parties to sustain conflict.

Forest Cover and Definition Forest Cover and Definition
Forest cover varies depending on how it is defined. The crown cover threshold and the land use criterion are, in most cases, the most critical factors defining forests.

Deforestation in Brazil Compared with the Area of Turkey Deforestation in Brazil Compared with the Area of Turkey
Over the past 40 years, about a fifth of Brazil’s Amazon rainforest has been deforested (Reuters 2008). Official statistics show that annual deforestation has been close to 20 000 square kilometres over the last 10 years, reaching a peak of 27 429 square kilometers in 2004, and then being reduced annually to 11 224 square kilometers in 2007 (INPE 2008).
