FORESTRY
What is forestry? Although there are important woodland areas in middle latitudes, such as the Black Forest of Germany, the main forest belts are those of the humid tropics in the equatorial and monsoon regions; and those in the cold temperate high latitudes. The extensive need for paper and other timber products in industrial countries, forested areas are principally seen as sources for such products; this has led to many environmental problems.

Special Interest Groups - Different Perspectives on Tropical Forests Special interest group Forestry perspective environmentalists - concerned about preservation of forests, conservation of biodiversity, and possible negative impacts of development (e.g. flooding, climate change) small farmers - interested in clearing the forests provides land to grow crops and provides family with economic security ranchers - interested in clearing the forests to sow pasture for cattle foresters - interested in managing forests for the sustainable flow of their goods and services and the maintenance of the biological functioning of their ecosystems loggers - interested in cutting commercial timbers to produce wood products communities & indigenous peoples - want more economic benefits from forests, guaranteed access for hunting and harvesting forest products, continued water supply politicians - developing the forests for agriculture or logging creates immediate jobs, prosperity and tax revenues for government; also temporarily relieves the pressures of need for farm land, jobs, and poverty alleviation international community - concerned about sustainable economic growth, the future of a world heritage, preservation of forests and their biodiversity
FUTURE?
Future demand for industrial wood products depends on income growth, population growth, technological change, growth in human capital, changes in tastes and preferences, and institutional and political change Projected consumption of nearly 3 billion cubic meters by 2050 The proportion of global timber from subtropical plantations (presently 10%) may increase to 40% by 2050 Fuelwood harvests will increase by 17% by 2050 under a low-GDP-growth scenario, but only by 4% under a high-growth scenario

How long can it last? No-one knows! ample wood fibre supply and demand would increase by 2010 demand would significantly exceed availability world’s forests are biologically capable of providing industrial wood consistent with consumption Pacific region are adequate to meet future demands, non-crisis future situation though not plentiful supplies.
Alternatives Steel, plastic, cement, stone for building Fossil fuel, nuclear or other sources for energy Can you think of an alternative to paper (technology???) RECYCLE Substituting non-wood products for wood products could increase carbon emissions
