Trees are cut down for use as building material, timber or sold as fuel (sometimes in the form of charcoal or timber), while cleared land is used as pasture for livestock and agricultural crops. The vast majority of agricultural activity resulting in deforestation is subsidized by government tax revenue . [ 89 ]
The planting of trees on marginal crop and pasture lands helps to incorporate carbon from atmospheric CO 2 into biomass. [53] [54] For this carbon sequestration process to succeed the carbon must not return to the atmosphere from biomass burning or rotting when the trees die. [55] To this end, land allotted to the trees must not be converted to ...
Cutting trees with the highest value and leaving those with lower value, often diseased or malformed trees, is referred to as high grading. It is sometimes called selective logging, and confused with selection cutting, the practice of managing stands by harvesting a proportion of trees. [9] Logging usually refers to above-ground forestry logging.
The trees that are no longer there can’t continue to convert carbon dioxide into oxygen, and the forests that grow back won’t capture enough carbon to break even for decades or centuries, if ...
Tree felling: The selected trees are cut down using chainsaws, harvesters, or other mechanized equipment. The felled trees are then prepared for further processing. Timber extraction: Once the trees are felled, loggers extract the timber from the forest by removing branches and cutting the tree trunks into logs of appropriate sizes for transport.
Clearcutting, clearfelling or clearcut logging is a forestry/logging practice in which most or all trees in an area are uniformly cut down. Along with shelterwood and seed tree harvests , it is used by foresters to create certain types of forest ecosystems and to promote select species [ 1 ] that require an abundance of sunlight or grow in ...
Carbon emissions from deforestation is an important issue to look at with the increasing problem of global warming.Currently, about 4% of B.C.′s total green house gas (GHG) yearly emissions are from deforestation, which is quite a low percentage compared to B.C.'s total GHG emissions, and works out to be about 6,200 hectares of forest land is converted to non-forest use per year.

Environmental legislation is administered by various Government Departments in various ministries. The Ministry of Environment, Water and Climate, however, administers most of those acts that deal with the environment directly. Zimbabwe is different from most Southern African countries in that its environmental legislation is comprehensive, and ...
