Global Forest Fragmentation Global Forest Fragmentation
Forest fragmentation can jeopardize the long-term health and vitality of the forest ecosystem. Forest fragmentation can also result in species loss as the size of a forest becomes too small to support a viable population of a certain plant or animal species, or if migratory routes and corridors cease to exist.

Wildlife Smuggling to in and from Nepal Wildlife Smuggling to in and from Nepal
Animals living in the forest are also at risk from poaching and bush-meat hunting. Intelligence gathering, regular mo - n itoring and strict enforcement are effective ways of curtailing both illegal logging and poaching activities in forests. The participation of local communities in these activities can facilitate implementation of laws and regulations and secure sustainability. Customs enforcement also plays a critical role in contro...

Forest Cover in Relation to Poverty Madagascar Forest Cover in Relation to Poverty Madagascar
Even though forests are often very important to households, there is surprisingly little knowledge on the actual level of household forest income and the role of such income in maintaining livelihoods. The evidence regarding the role of forests in allowing households to move out of poverty is scant and mixed; there are examples indicating that income from forests allows households to accumulate assets and escape poverty. However, by wa...

According to the Food and Agriculture Organization of the United Nations (FAO) there are at present just under 4 billion hectares of forest in the world, covering in all about 30 per cent of the world’s land area (FAO 2006a).

Forest Carbon Stock per Region Forest Carbon Stock per Region
Carbon stocks in land based ecosystems are distributed irregularly between tropical and northern latitudes but are mostly concentrated in forest ecosystems and wetlands. Recent research suggests tropical forests play an even more important role in absorbing carbon than previously thought, taking up 1 Gt of carbon every year, or about 40 per cent of the total for land based absorption (Britton et al. 2007).

Annual Net Change in Forest Area Annual Net Change in Forest Area
The net change in forest area (loss and gain) describes the sum of all changes in forest area over a specific period of time (including reductions due to deforestation and disasters, and increases due to afforestation and expansion of forests during the period).

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.

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).

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.

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).
