What is importance of tree plantation in sustainable agriculture?
Tree Plantation drives combat many environmental issues like deforestation, erosion of soil, desertification in semi-arid areas, global warming and hence enhancing the beauty and balance of the environment. Trees absorb harmful gases and emit oxygen resulting in an increase in oxygen supply.
Are plantation forest harming the natural forest?
However, these slow-growing forests are unable to meet current demand, resulting in the loss and degradation of forest. Plantation forests have the potential to supply the bulk of humanity’s wood needs on a long-term basis, and so reduce to acceptable limits the harvest pressures on natural forests.
How does plantation timber impact on the environment?
Farm forestry can perform many different functions besides just providing another revenue source. The trees can serve as a windbreak, help fight soil erosion, provide shelter and shade for livestock, protect the soil by improving its nutrients, help prevent flooding and help promote biodiversity.
